What ChatGPT says about Mistral.
Mistral Associates - News October 2025
Mistral has ditched its Escrow partner Paypal. Due to escalating charges, dubious behaviour and constant changes of rules imposed upon clients. Always in favour of Paypal, so 'Moving the goalposts after the game has started!'
For 25 years Mistral relied upon financial Credit Card and Debit Card transaction Escrow services through then internationally renowned Digital River. Until Digital River's sudden and chaotic demise around five years ago. From our experience through what could only be described as grossly incompetent management. Thus leaving Mistral with no choice but to embark upon expensive legal action to recover funds owed to us.
Our decision then was to open a new account with Paypal. The decision has proven less than satisfactory. At the same time Mistral opened an Escrow fund transfer account with Wise, then named 'Transfer Wise'. Wise performance has been exemplary, with faultless fund transfers between Mistral's valued, loyal clients and Mistral's bankers. Providing always prompt, clear and courteous service and advice.
More recently Wise has introduced an albeit limited Credit Card and Debit Card fee collection service. Via their Secure Server and utilising Maestro, Master Card and Visa cards. Very simple for users to operate and with charges to Mistral a mere fraction of PayPal's exorbitant fees. Therby negating any need for Mistral to increase access Licence fees.
Links to Wise payment routines Credit and Debit Card service are provided on around 1,500 of Mistral's 5,250 on-line Web pages. Including this page.
Mistral customers choosing to remit payments by ITT (International Telegraphic Transfer) and BACS may of course continue to do so. No changes have been made and clear details are always provided on Mistral invoices.

In four decades and with over half a million installations across 140 nations we cannot recall anyone ever contacting us to ask how our Expert System software works. Even from users in countries where none of the 10 languages Mistral's programs simultaneously run in is their native language. Graphical and icon support is so strong that providing a user understands just a few key RAC industry, international measurement units, such as kW or Btu/hr and °C or °F then all the rest only requires 'Following the Pictures' to run the programs successfully. However there can be some non-essential, peripheral functions or features that users are unaware of. Unaware because Mistral software is so easy and intuitive to use users are often blissfully unaware the total system is supported by over 2,500 illustrated, 'dynamically linked' and 'focused' Help pages.
One such 'non-essential' feature did though slip through the net as far as having a very comprehensive explanation of how it works. So last month we set about correcting that.
All Mistral's load calculation programs automatically communicate seamlessly with independent RAC equipment selection programs and associated interactive databases. Allowing faultless selection of refrigeration Unit Coolers, Condensers, Condensing Units, Compressors, Split System A/C and more besides. Whilst not essential wouldn't it be nice if a Unit Cooler, or multiples of them, could be added to a Coldroom floor plan drawing and included in the presentation quality automatically generated and instant printout?" Condensing units too. Even better! Something incidentally that AI does not stand a chance of doing, and never will!). Well you can. It's always been possible. No other developer that we are aware of can achieve this but Mistral has done it for the past four decades!
Hence we have added a better explanation in the programs' interactive Help pages.

A M Mouran 1901 - 1968, under his nom de plume Cassandre, was a highly talented and pioneering commercial artist of the early 20c. Designing celebrated posters and wall painting advertisements for explosive growth in express rail travel, luxury cruise liners and popular beverages. Originating his own now classical, post Cubism, Art Deco style his works once adorned seemingly almost every street corner, rail trackside and commercial building in France. Creator of unique, charming, unmistakably French icons. Sadly now few remain and of those that do then as they are no longer maintained, also a now proscribed advertising medium, their days are numbered as they inexorably crumble away. A huge loss to one of France's unique, iconic charms.
Sadly Cassandre committed suicide in June 1968, following a bout of depression which many now recognise was aggravated by wholly unwarranted, ignorant criticism of much of his admirable, stimulating work.
Unnoticed by many but all designed for a serious purpose. Mistral's heavy reliance upon simple but meaningful imagery and icons adopts much of the ethos created by Cassandre. Cassandre strongly believed commercial images had to quickly make unambiguous impressions upon their target audience. Particularly those passengers sitting comfortably in an express train passing one of his creations at nigh on 150 kilometres per hour!
Mistral's thousands of program icons have also all been painstakingly created to make instant impressions upon program users. These images are very effective. Enabling around 25% of users, not fluent in any of Mistral's ten
published languages, to nonetheless operate programs successfully.
So what is the connection with Cassandre's legacy? Well Mistral's HQ visitor reception area presented a six metre long blank wall. An ideal site for creating a tribute to one of our heroes. The subtle 'reverse' perspective of the text practically shouts at the observer. Little chance of misunderstanding as it flashed past on the trackside at nearly a hundred miles per hour! Two days this July for artisans to create the 'Shiplap' wall façade and two weeks to research and then create the mural. At least one iconic example to be saved for France.

For 25 years Mistral's website featured a 'Search' tool.
Visitors to Mistral's vast website could search for anything, for example, from Altitude to Apple Juice or Pipe Sizing to Psychrometrics etc., etc.
This tool was provided through a service offered by well known Google. However, there were problems with it. Firstly it was slow. Sometimes painfully so. Secondly it was unreliable; frequently failing to find and lead users to information Mistral knew for certain is included in the website. Finally, it was confusing. Offering to help a visitor to Mistral's website the facility to search globally, across the entire planet. Hardly helpful. Either to our visitors or of course to us! Anyway, who needs Google to boast over "175,000 'results' in 15 seconds" when barely any of them contain the information the visitor sought?
Who needs so called Artificial Intelligence when it is frequently wrong?
Our mantra - "Mistral doesn't use Artificial Intelligence. All Mistral's intelligence is real!"
So five years ago Mistral abandoned this Search tool. It was deleted from our website. Despite its shortcomings it was missed by some, and they kindly informed us so. Happily, rather late than never, Mistral has developed its own dedicated Search Engine. It is now active. It is accessible directly and immediately from all core site web pages. It is extremely accurate and importantly, it is fast. Actually faster than fast. Mistral 'Search' finds results practically instantly.

Mistral is experiencing its best year ever, since inception in 1984, 41 years ago, and then actually starting to trade in ernest six years later in 1990. Following six years of concentrated largley unpaid R & D work, with additional largely funded input from another nine highy qualified and experienced professionals.
We put this exceptional and frankly, unexpected growth down to AI actually pushing more prospects towards us. Rather than robbing us of clients. Mistral's year on year sales are around 20% up on previous best.
Mistral's first major setback was Brexit. It threatened to finish us. For lots and lots of reasons, too long to list and explain here. We still suffer a new post Brexit French Draconian tax regime but every one of our valued clients accepted us having to apply above inflation price increases to cover the losses. That or we go under!
Having recovered from that near crisis we faced the Pandemic. This Chinese weaponised Covid 19 virus practically suspended a major part of Mistral's global market place for up to 18 months. Finally cutting revenue by 40%. With no 'Cost of Sales' to speak of Mistral was not in a position to reduce operating costs without letting go of loyal staff. And that we were not prepared to do. So once again, since foundation in 1984, the (surviving) founding Directors forwent their salaries.

Two adjustments made to recently launched 'Coldwind Pro' add-on module 'Borawind'.
'Borawind' shares its main design data input form with it's host program 'Coldwind Pro'. Access to the main form 'Personnel' input dialog is now blocked when running in 'Borawind' mode. Blast Freezer operators are generally not in the habit of including members of their staff inside 90 minute Blast Freezing operations!
In full agreement with a number of 'Borawind' users there can be valid reasons for discounting or nulifying product Sensible heat loads from the final calculation (for more advice see:- borawind_cautions.html. However the use of the tool to do this for Blast Chillers has now been blocked. For obvious reasons. It is therefore retained for optional use in Blast Freezing design projects only.

Mistral completed calculation files don't simply save the project results, but also contain a record of every procedure and critically relevant key press that was used to create that result.
Why is this significant? Why is this important? Well it means a calculation result file can be opened as a fully functioning active procedure and which allows full input editing, then re-saved, thus over-writing the penultimate result,
or even more advantageously if wished, saving
So what? Cynics might argue. The 'what' meant the task of both creating and continuously maintaining Mistral's Microsoft Code Signed software code was and is at least ten times more complicated (AND three times more expensive!) than it might otherwise be.
Mistral Expert System Software provides licensed users with enormous advantages over users of lesser systems. Scores of numerous features that AI (Artificial Intelligence) cannot get even close to matching. Mistral is of the opinion that software unable to match these abilities isn't up to the job, and thus should be avoided!
Importantly too, from Mistral's earliest days following the company's foundation in 1984 the founders adopted a policy that ensured the constantly evolving and improving total array of RAC Application Engineering software would always be made to be 'backwardly compatible'. Even following countless new computer Operating System introductions and upgrades. For example, a refrigerated Coldroom load calculation file result saved in the year 1995 can still be opened, edited and re-saved, using Mistral's dynamically error trapped load calculation software issued in 2025. Thirty years and over 780 new program 'compilations' on! Quite simply, unassailable in the world of IT. That, friends, is both what, and why you get what you pay for with Mistral!

Mistral's 'Expert System Software' is a Managed Software System.
No matter how good software is, no matter how well designed and how thoroughly proven, 'Expert System Software' can never be considered to be
finished. Any software developer thinking otherwise is only deluding themselves! There is always room for improvement; by streamlining functions or adding new features for example. Also of course there are the
massive quantity of proprietary databases, containing tens of thousands of interactively selectable RAC equipment. Unit Coolers, Condensers, Condensing Units, Compressors, Packaged A/C and Refrigeration Systems etc.
These must be kept up to date, especially to meet constant advances in refrigeration technology. Therefore Mistral operates its 'Expert System Software' as an annually renewable 'Managed' Software System. Sparing business managers of an essential but very onerous task.
Annual renewal is not though performed automatically. Mistral never presumes that its valued Licenced users throughout the world will always wish to renew their licences. Even though around 99% always do! Mistral also never automatically bills Licensees by Direct Debit and only invites licence renewal, leaving this decision totally under the control of its Licensees. But when to renew?
The answer is that licenced users can freely renew at ANY time during an active licence period, if they wish. So as to always have access to the very latest data and also to ensure compatibility with unrelenting advances in computer Operating System technology. However, towards the end of an annual licenced access period a notice will automatically appear advising how many days of access are remaining. Actually at the 28 days point. From that point repeat reminders occur at 7 day intervals. During the last 7 days reminders appear daily. This system has been in place for the past three decades, and now there is a further enhancement.
What if a company wishes to know precisely when renewal will be essentially required, even months before it is due? For annual budgeting purposes for example. Mistral has therefore introduced an additional function to its
Registration dialog and which is accessed through the 'Master' Program Group illustrated program launch forms.
Click HERE for an example.
At bottom left of each 'Master' Program Group illustrated program launch form there is this icon button:- 
Clicking on the icon produces Mistral's familiar, standard program installation Registration & Activation form. This form now displays the current installation access expiry date.

New Year - Mistral launches a new product
for students, self employed and Start-ups.
Listening to our valued customers - As always!
For 3 month access when you need it.
Don't pay when you don't need to.
français
Mistral does not offer discounts. Why not? Because Mistral doesn't need to! Discounts must be funded, and that means paid for by long standing, loyal customers.
Mistral believes this to be unfair treatment of the very people our highly ethical organisation depends upon for its survival.
Mistral does not offer so called Demos. Why not? Because Mistral doesn't need to! As the world's indisputable leader of the Expert System software genre it alone created over four decades ago, Mistral's reputation for infallible reliability, accuracy, ease and speed of use, speaks for itself. Demos must be funded, and that means paid for. Again, loyal customers are not expected to fund Sales and Marketing campaigns.
However, Mistral recognises that not every RAC engineer needs to access Mistral's software products upon a daily basis. So what is the solution? Mistral's popular Subscription Licence, created specifically for Start-ups and cash strapped students, has been around for a long while now. For twenty years actually. At just UK £165 per annum for the single user licence fee, it rates as one of the lowest annual access licence fees for any Expert System software system in the world. Even this price though, the cost of a decent meal for two in any popular quality pub or restaurant, can be too much if likely to be used maybe only two or three times a year.
Mistral introduces - 'Fourthwind'. Offering access for three months only, for just a quarter of the usual fee.
No penalties. Certainly no hidden charges (Mistral never does that, unlike many IT companies and service providers in the world!). Exactly one quarter of the annual fee, for exactly one quarter of the access period.
No requirement to re-order at the end of an access term. No limit to the amount of times access can be purchased. Even if long periods of time, that is gaps, exist between licence periods.
Fee
'Fixed in Perpetuity'.
All previously saved calculation results still accessible in subsequent re-installations. For re-opening, editing if necessary, and re-saved. Even years later! So pay for access when needed and don't pay when you don't!
No automatic billing and certainly no Direct Debit Mandate requirement. Mistral has never asked its valued customers to enter into such agreements, and never will. No convoluted cancellation procedures.

"Every Little Helps!" Sorry Tesco, but we didn't think you would mind!
After all, our two companies have supported each other for decades now!
Mistral's Coldwind Pro refrigeration load calculation Expert System Software is quick. Very, very quick! The fastest such software in the world (probably! 
). Considering that with 'Coldwind's 'Quick Selection' routine regular users can complete unique new Coldroom Design projects, highly accurately, in under 10 seconds.
However, creating a Dual Compartment Chiller/Freezer from scratch can take a little time, 10 minutes or so, and also requires a little ingenuity. So Mistral has made this operation even simpler and faster too! By creating a couple of fully customizeable pre-engineered, design 'Templates'.
Dual_Compartment_General_Purpose_2x14.5m³.cwc
and
Dual_Compartment_General_Purpose_2x17.6m³.cwc
Room sizes are typical for Dual Compartment applications and fully editable (customizable). Both spaces are for General Purpose food products. These can both be changed in an instant, using Mistral's
huge array of icon illustrated, Food and Miscellaneous Products, interactive databases.
Just two #.cwc files ('Coldwind' calculation files) at present but if these prove popular then Mistral will create more.
Mistral would be delighted to hear your suggestions, so please don't hesitate to contact us with your ideas.

With Mistral even the little things count!
As computer monitors have become larger over the years, and at the same time pixels which make up images have become smaller, then Mistral's original program form designs appeared to become smaller. This has meant Mistral programs have to be constantly re-written. To keep up with these and other technological advances. Not an inexpensive task!
The most recent changes have been in the GUI (active Graphical User Interface) called the Room Designer. Mistral has increased the size of what are called Wall Nodes so as to make them easier to accept Mouse point tip focus.
How does this help? Wall Nodes allow for rooms, both for A/C projects and for Refrigeration Coldrooms, to be increased or reduced in size for example. Simply by focusing the Mouse cursor over them, then while holding down the left Mouse button, Dragging & Dropping the wall node into a new position on the Design Form. Even to create rooms with walls set at angles and also to merge two rooms together to create Dual Compartment Cold Rooms and suites of linked Coldrooms. The same nodes are also used to rotate Unit coolers to match angled wall positions too.
All are highly practical program features which quite frankly are not provided for professional RAC engineers by Mistral imitators or plagiarists!
Mistral's 'COLDWIND' series of coldroom and freezer Refrigeration Load calculation programs have always included the facility to add product containers, racking, stillages and trolleys etc., in the Food Product data selection procedure.
However, it is recognised that such additional data is not always neccessary. As storage items inside the room are generally static and thus already down to Design Operation Temperature. Also the thermal properties, along with the relatively much smaller mass of these items does not make a substantial difference to the overall Primary Refrigeration Load. However, this is not always the case, and trolleys and containers, often made from stainless steel and aluminium, are sometimes introduced into the refrigerated space simultaneously with the food product. Also at the same entry temperature of course.
Mistral has therefore introduced a simple 'Prompt' form, reminding users of the possible need to add additional items to the Product Load procedure. If not required then a single button click being all that is necessary to clear the message.

Morrisons takes the initiative to challenge a century old food storage safety standard.
For more than a hundred years the internationally accepted Design Operating Temperature standard for food freezer rooms has been -18°C, -0.4°F (actually in practice 0°F).
Frequently -21°C and even -25°C for longer term storage of meat.
Mistral applauds the initiative taken by one of its hundreds of household name 'Specifiers' in trialing an increase in food product storage temperatures in its freezer stores, in its vast distribution centres and even in supermarket retail display cases. Planned, we are told, for eventual roll out across the entire nation.
A bold break from a century old established, universally accepted and previously never before challenged food storage safety standard.
Mistral would though argue that the energy savings, even if adopted and imitated globally, are unlikely to 'Save the Planet'. Certainly not by the 8.6% global energy saving recently appearing in related, uncorroborated publicity. Unlikely to 'Save the Planet'! If indeed it needs saving at all and which, as one of the world's undisputed leading authorities in global energy management, Mistral anyway disputes.
Yes, Morrisons' recent announcement of declaring that it plans to increase food freezer store temperatures by 3 Kelvin (3 degrees Celsius to the layman), from -18°C to -15°C is credit worthy. But not for all the reasons Morrisons, one of the UKs leading and justifiably most populer food retailers, actually claims. It would take too long to explain in this short bulletin all of the technical reasons. Suffice to say the technicalities of reduction of dangerous to human health pathogens, in the nations's food supply 'Cold Chain', are complicated. Mistral does though agree it will be safe for the consumer to have the proposed specification changes made. And yes, it will save a considerable amount of energy.
To that end Mistral is currently working to add Morrisons' latest design standards specification to the millions of similar data items it constantly makes available to professional Refrigeration Engineers, Consultants and Specifiers, throughout the entire civilised world.

'Demo' software. Never say never again! Mistral changes policy.

Mistral always maintained that it would not create free so called 'Demo' versions of its Expert System Software products. Apart from the costs associated with doing so, and which would have to be recovered from loyal, fee paying customers, there is a well known saying prevalent in the IT industry:- "People asking for Demos rarely have any intention of going through to making any purchase." Generally plagiarists, hackers and freeloaders, or simply time wasters. Another fact is that no one (other than companies amalgamating, a few that ceased trading or sadly, the deceased) has ever closed a Mistral account after signing up. Many of whom signed up over three decades ago. All the proof we need that Mistral unfailingly meets customer requirements. And some! Always at fair and equitable prices. Customer testimonials
Neither Mistral nor our loyal customers wish to subsidise competitors happy to profit from decades of our arduous hard work and huge, ongoing financial investment. Gaining orders at our expense, but without ever considering it only fair to contribute towards our costs. For this reason Mistral has offered short term, usually 30 day access of its products at a very low, break even fee. Recently however Mistral has been asked, not unreasonably, for a demo version with just 24 hours access. More than sufficient time for a serious prospect to see for themselves how good Mistral's products are and to confirm that these 'Do what it says on the tin.'
To offer this against a nominal fee would likely not recover Mistral's costs in administering the charge. Yes! Collecting and accounting for revenue costs money too! So Mistral is offering this service for free. Contrary to previously declared policy. Naturally downloaders are monitored and will be unable to make repeated requests, as this would be grossly unfair to Mistral's thousands of fee paying licensees across the entire planet.
Click here Free 24 hour Licence if you have never before installed any Mistral Expert System software product. But ONLY if you have never installed any Mistral product before, as that may 'over-rule' access to currently licenced installations which may then need reinstalling.

What if I don't know the size of room that is needed?
Can Mistral's Coldwind refrigeration load calculation program actually advise what the size of a room should be in the first place?
The answer is yes. Whilst Coldwind normally 'presumes' room dimensions are already known, what if they aren't? What if a client approaches you and asks for example "What size of chiller room do I need to store 17.5 tonnes of fresh meat?
Mistral's carefully researched 'Quick Selection' room sizing logic revolves around established industry standards and operating conditions. As laid down by a consensus of leading 'End User' specifiers. Such as major supermarket groups, 'Fast Food' franchises, food wholesalers and distributors, and government bodies.
A wealth of information which took years of diligent, arduous research work and consulting to assemble and then prove. Before the complex task of coding could even begin. Although largely unseen this vast amount of data works in the background and has been responsible for the successful design of tens, probably even hundreds of thousands of coldstores and freezers, throughout the entire world over the past four decades. From small restaurant 'Walk-ins' to the world's largest, in some cases multi-story coldstores. The results that this interactive data creates have never been challenged, have never been argued as defective in any way, and have never been questioned as to total reliability.
So how can it help work 'in reverse' so to speak, and work out what is the best size for a room in the first place? Even before dimensions have been decided.
Simple. A little bit of common sense is required.
Any competent refrigeration engineer would or should be sufficiently experienced to have some idea, even if not yet sure of the precise dimensions needed. To both fit the available space and the all important client's budget. Mistral Expert System software will come up with the most COMPETITIVE, and importantly safe and efficient, professionally engineered solution.
Start off by using Mistral's Coldwind 'Quick Selection' procedure and make an educated guess as to dimensions. This takes no more than 7 to 10 seconds!
With a solution now presented on screen, hover the Mouse cursor over the food category icon that was selected. This will display additional information about what design parameters, based upon established industry best practices, that were used for the project calculation. Naturally these will vary from the thousands of data items for product type to type, along with all other considerations such as ambient, design operation temperature, product entry temperature, recommended pull down times, machinery, lighting, personnel and other possible load items.
If the first 'intelligent guess' over or under estimated the required room size then with Mistral's unique, 'Dynamically Error Trapped' and Parallel Mode Operation, only a matter of seconds is needed to return to the graphical room design user interface to make adjustments. 'Drag & Drop' wall nodes to either reduce or increase the room size. Every calculation needed to accurately recalculate the refigeration load will be automatically made, practically instantly! Mistral knows of no other load calculation software in the world that can do this. Let alone do this instantly!
In four decades Mistral has never seen any other software capable of achieving this, AND importantly, to do so with total reliability and accuracy.

You get what you pay for!
The original King James Bible was created in the year 1611. It contained 784,137 words.
The New King James Bible modernised English version was published in 1982. It contains 770,430 words and some versions include up to around 200 illustrations.
Mistral commenced research and development of its RAC Application Engineering Expert System software in 1984. The current version was last edited around an hour ago,
and will likely be edited or added to again within the next hour. It currently contains approximately fifteen and a half million legible* words, in 10 languages.
twenty times more than the New King James Bible. The system also contains around 17,500 hyperlinked photographic images, dimensioned line drawings, and thousands of 'linguistics beating' guide icons.
Very few people have ever or will ever read the Bible from end to end. Similarly Mistral would not expect any single person to ever see more than around 5% of its Expert System software. Furthermore, two engineers in adjacent offices may never see the same 5% as each other, but the system has to provide for both, along with everyone else.
