In case no one has noticed, it has been quite warm in the Northern Hemisphere these past couple of months!
Colour matters! Coldwind deals with containers and trucks as well as all types of coldstore.
Scientifically, varying reflectance as a function of surface colour is described under the phenomenon known as albedo factor. Over the total exposed surface area
of a standard 40' refrigerated freight container reflectance differences due to colour can account for as much as 20% of the refrigeration load. In the tropics this
difference can amount to more than 1kW. Not much perhaps. Until an organisation is supplying equipment and power for 40,000 of them!
Mistral's legendary 'Coldwind Pro' multi-task program.
Completing tasks highly accurately in less than two minutes that can take even experienced engineers more than a couple of hours to do manually!
Reduce costs! At the same time improve your competitiveness to WIN more orders!
Bugs happen! Any developer pretending they don't is only deluding themselves. However this wasn't so much a bug we just dealt with but more a programming anomaly.
An anomaly caused by Microsoft making unnecessary Windows, 'Critical Upgrade', so called 'improvements'. Without warning and without thinking through the consequences! It needed overcoming and improving by us nonetheless.
In common with virtually all user operable PC software, Mistral's programs are launched from a Desktop icon. In Mistral's case clicking on this opens a form on the desktop known as a Program Group.
Larger software systems, or Apps as nerds and children like to refer to them these days need them. Again in Mistral's case, we try and make our Program Group forms comprehensive, informative and even entertaining.
"All work and no play makes Jack a dull boy" as the saying goes!
In Mistral's larger program compendium the Program Group also includes an 'Always on Top' feature.
Activating 'Always on Top' makes the Mistral Program Group form dominant such that it will always appear visible over the top of any other App running and visible on the Desktop at the same time.
Mistral's Program Group form is intentionally kept compact so as to make this feasible; And useful!
It is not unusual for an engineer to be working with many programs at the same time and being able to see a Program Group allowing App launches instantly at all times,
and without having to contend with the frequent idiosyncrasies of Microsoft Windows unexpectedly hiding things when you least want it to, is certainly useful.
However, up until now, using 'Always on Top' in some Mistral default Program Group forms meant that the launched App gets concealed behind the Program Group form.
Windows had aggravated seeing the simple solution to this by discontinuing showing the App is open on the bottom Tool bar, when the App is running.
This following yet another Microsoft unnecessary improvement which did nothing of the sort.
If the small icon indicating that the App is actually running as it should then the user would realise all they had to do is slide the Program Group away to left or to right, so as to reveal the open App.
One of Windows' improvements defeated this!
To overcome the problem Mistral now forces an App form to appear slightly to the right of and below the Program Group form. Thereby making it obvious the App has opened as it should.
Users then have options of sliding the Program Group form away to one side, or toggling off 'Always on Top', or even closing the Program Group, leaving the selected App still running.
A simple and effective solution? Yes, simple to say it but one which took over a week of program coding work, testing, re-compiling thousands of system files, and server uploading to achieve. At a four figure cost!

Finally, don't forget that all Mistral's larger systems feature switching between its larger, illustrated Program Forms and the ultra compact 'Menu Strip'.
This can be dragged and dropped with the Mouse to either the top or bottom of the screen, and thus well clear of any other currently running Apps.
Click!Air Infiltration Latent loads in cold rooms and freezers.
For reasons that the technical reality of accurate Air Infiltration Latent heat gains into cold rooms, especially freezers, is often not as simple as the basic science might otherwise suggest, Mistral has up until now only ever shown the Total Air Infiltration Load for cold rooms and freezers. In other words the sum of Sensible plus Latent.
A policy applied only to the Coldwind group of programs and not those in the Airwind and Cellwind Groups.
However, following requests from a couple of highly respected, leading RAC contracting companies, Mistral has agreed to reverse this policy, which had been in place for over 30 years. Air Infiltration 'best estimate' of Latent gains will now be shown for both cold rooms (chillers) and freezers, as a separate item.
The coding change is, as always with Mistral, 'backwardly compatible'. Meaning refrigeration calculation load results files, created as far back as the first Windows version release in 1995, can still be opened, edited and re-saved. Even though first releases were 16 bit programs and currently they are 32 bit.
The new release, version 5.2r, will automatically recompute reopened #.cwc files and adjust results accordingly.

Mistral has ditched its escrow partner (on-line commercial bank) after 27 years.
In favour of switching to PayPal.
Although starting off well enough, serving us from 1995, following various take-overs our escrow partner's performance had steadily gone downhill. With ever more frequent yet avoidable outages, clueless and indifferent staff,
slow response times, ludicrous new bureaucratic rules, deceptive tax handling and illogical, counter intuitive interfaces, finally forcing our hand.
Distributing sophisticated, large and security controlled Expert Software Systems on-line, throughout the entire world 24/7, is no easy task. Simply purging Mistral's 3,300+ page, multilingual website of deeply entrenched, secure links and support pages to effectively a bank, actually took us over a week. In the meantime we are pleased to say we managed to keep disruption to our customers to an absolute minimum.
We are also pleased to report that switching to PayPal was actually much easier and quicker than we had anticipated. PayPal appear to understand our marketplace role well and were extremely helpful. PayPal also have the advantage that there can be only very few people in the world who have not heard of them, and trust them. Whereas our outgoing escrow partner, although claiming to be the largest of their genre in the world, we now very much doubt.
Mistral's 'Ex' escrow partner management team appeared to us at least to be bearing a grudge against their employers, and thus determined to destroy them! We won't mention their name on these pages but if you wish to know, and are considering signing up an escrow partner for on-line trading yourselves, then please don't hesitate in contacting us to ask. We will be happy to provide you with 'Chapter and Verse' of their shortcomings and failings.
Mistral Associates - News June 2022
Mistral is pleased to announce that by popular request industry renowned Hemsec insulated panel data has been added to 'Airwind Pro' A/C load calculation, 'Cellwind Pro' Beer & Wine Cellar load calculation,
'Coldwind Pro' Coldroom & Freezer load calculation and 'Prepwind' Food Preparation load calculation program's interactive databases.

Especially for all our friends in the Azores, Bermuda, Canaries, Gibraltar, Hawaii, Maldives, La Réunion Island, Singapore and not forgetting others whose countries weren't easy to find on Mistral's interactive program download locator* map.
Now you will find it much easier!
There are now an astonishing 4,740,768 pre-engineered, Quick Selection calculation files in Mistral's 'Coldwind Pro' multi-lingual, refrigeration load calculation program.
It looks more impressive to write this in words rather than figures. Four million, seven hundred and forty thousand, seven hundred and sixty eight.
Yet these are so neatly 'nested', in tiered menus, that a seasoned program user can quickly 'zero in' and open one in around seven seconds. And the calculation files are all still fully user editable.

Back in 1984, thirty eight years ago, when the urgent need for intelligent, logical and intuitive 'Expert System' software for our industry became blindingly apparent, Mistral was formed
by a small group of industry peers to meet that need.
Mistral's 'Mission Statement' at that time, now described as 'Mistral's Commitment', to use a much hackneyed expression but nonetheless still as relevant today as it was then, is:-
"Bringing the benefits of computerisation to our industry - without the historically associated problems."
What was not immediately apparent then, not even to the founding partners, was just how vast that objective would turn out to be. Saying "Heat load calculation." Takes but a second.
However it took another five years intensive research, input and effort, more often than not totally unpaid, before the founders were satisfied they had a viable, safe and marketable software product.
No one can deny it was an instant success. The fact that more engineering professionals across the entire globe rely upon Mistral's RAC Application Engineering systems than all other systems since
offered (and disappeared!) than any other, even when all others are added together, is testament to that!
However, complacency is not a state of mind that exists amongst Mistral's highly qualified and experienced team members. Many of whom have been part of that team from the very beginning.
All past our 'use by date' as is gleefully bandied around our offices.
As founding Director I cannot recall one single day, 365 days of the year, vacations or not (usually not!), when someone, somewhere in Mistral's team hasn't been working around the
clock improving something or adding something so as to make our friends in our industry's lives that little bit better. Notone, single, day!
If you've got this far then maybe you are wondering what it is we are about to say. Thank you for waiting patiently!
Mistral's programs are so vast they often practically run themselves. Frequently doing so in seconds, completing tasks with razor sharp accuracy that used to
take seasoned RAC engineers hours, or even days, of repetitively boring but essential number crunching work. Many features, functions and capabilities though are missed or go unnoticed.
Particularly those features that are rarely needed. Mistral are therefore addressing that situation. Simply by enhancing the existing focused, multi-thousand page Help system,
the automated cue card advice system and last but not least the essential 'dynamic, Error Trapping' systems.
Just because an experienced engineer can do it manually, with tables
and a calculator, does not mean they wish to spend hundreds of times more of that amount of time doing it!
From April users will see simple, plain language automatic hints which relate to whatever or wherever they are in a Mistral program at that time.
In whatever language the user has chosen for their current session. Not in the form of drop down forms that annoyingly require closing just so as to continue,
as happens in so much appallingly badly produced software, and particularly in web pages, today.
Even 38 years later, sadly still so few software developers can even scratch the surface of Mistral's achievement in producing easy to use, intuitive, fast and totally reliable software!
Cost to Mistral of creating 120 new, multi-lingual, program cue cards. Coding, compiling, proving, incorporating and uploading to servers: 620 Euros.

This might come as a surprise to many but in order to meet the demands of Mistral's more than 25,000 registered users across the entire planet the company distributes over 200 versions or tailored variants.
These are needed to meet a plethora of challenges Expert System software developers serving a global market have to face. From computer Operating System (Windows) variants to language and national region
differences, keyboard and monitor types, meteorology, local legislative requirements, even which decimal point deliminator is in use, comma or period.
Most of these variations, around 170, can be controlled through the 24 character alpha-numeric Access Registration Code. Even with Mistral's courtesy of omitting potentially confusing characters such as
O and 0 and 1, I and l for example, the permutations run into trillions. Infinity for all practical purposes. Therefore a Mistral program will already be set to use decimal commas in Spain for example,
instead of period or full stop as in the United Kingdom. All without installers having to make further adjustments.
However around 30 out of Mistral's more than 200 'products' do require completely separate program file compendium.
Why is this important to mention here? Well apart from reminding hopeful but naive imitators and plagiarists they will be facing over three decades of research and development by highly qualified engineers and programmers
working together as a team just to reach Mistral's standards this explains why Mistral urges downloaders to ensure they select the right download and Access Code form on Mistral's website.
Mistral tries to make this exercise as simple and trouble free as possible. By use of interactive 'clickable' world maps for example. Downloaders are urged to click on these maps on the region corresponding
with their location. The web page which follows should then be the right one for taking them to their download button.

A problem arises though where a licensee from say Cambridge, UK clicks on the world map over the USA, aware that English language form completion and program operation will be offered, yet unaware English USA is not the same
as English International.
Furthermore, Mistral's multi-lingual and language switchable programs, switchable even after installation may be offered in the same language for many world regions. English, French, Spanish and Portuguese, often in conjunction with other
languages are offered throughout the world for example. But this does not mean the programs and interactive databases are identical.
Finally, Mistral tries to answer every licensee who contacts by Email within minutes. However Mistral as an international provider naturally receives hundreds of Emails every day. Sometimes delays are
inevitable and also can be aggravated by inexplicable international routing delays, over which Mistral obviously has no control. Mistral's staff therefore do not find it amusing when someone runs into problems
installing and after spending twenty minutes or so trying to sort the problem out only to discover that a person in Harrogate, United Kingdom thought it 'funny' to click first upon Sweden and then upon English as
preferred language. Swedes speak English too! The program variant Swedes receive though when downloading will have been tailored to operate in Norrköping, Sweden and not Harrogate in North Yorkshire!
Mistral's staff are not noted for becoming violent but such antics do increase the risk!
