“Bring back Windy!”

We hear you protest.


Sorry. Truly. We really are!

Windy, Mistral’s servile, nerdy, lovable (steady on!) little windswept, ginger friend is almost 25 now. We had thought to retire him. Following his illustrious, if somewhat drafty career, obedienly proffering advice to our tens of thousands of RAC friends from every corner of the globe. OK, we weren’t planning on removing the familiar program feature completely. Just to replace Windy with someone more, dare we say? Sexy!

monroeChris, our veteran last surviving founder, thought someone 'sexy' would go down well. Until some of the saner amongst our team persuaded him that with F1 ‘Grid Girls’ recently consigned to the PC annals of history, along with cheerleaders, miniskirts and even scantily clad weather forecasters all about to go the same way, then maybe 'sexy' wasn't a good idea.

Apart from which Windy does represent one of the bastion icons in Mistral’s armoury. Despite core programs such as 'Airwind' and 'Coldwind' now well over their 750th issue since launch, the programs intentionally remain familiar so that users always feel comfortable and confident when operating them. So familiar indeed that a handful of the less observant have even accused Mistral of not doing very much over the past quarter century! A scurrilous and wholly unwarranted accusation. The original 'Airwind, Cellwind' and 'Coldwind' wouldn’t even run under Microsoft’s latest Windows Operating Systems! And yet the programs are all still capable of opening a calculation file created in say 1994, allowing it to be edited and then resaved again. What we call ‘backward compatibility’ and something almost unprecedented in the viciously fast moving world of software development.

So, in response to protests, Mistral promises Windy will stay. Just as his hypothermic little self has done for the past quarter century!

For those of you so familiar with all of Mistral’s more advanced features, and it should be said, features totally lacking in every one of Mistral’s imitators’ offerings that you've long since forgotten Windy's sage suggestions here's the full list:-

AIRWIND and AIRWIND Pro tips (scroll down for COLDWIND tips)

No. 1 "If you select Ventilation and enter a figure you are introducing air into the room." Unless you have a powered extract system as well then you have got 'positive air pressure' in your room. In this situation it isn't wise to select Infiltration as well or you might risk 'over-engineering' the job.


No. 2 "Complicated room with lots of walls but some of them share common features?" Save time selecting the features that are common to each wall by holding down the Ctrl key at the same time as left Mouse clicking on the wall labels. You can then go on to choose materials, doors, windows etc. for all of the walls you have selected, all in one go! (See Tip of the Day No. 11 as well about another and similar shortcut involving 'dragging and dropping' with your Mouse cursor)


No. 3 "Got two or three jobs that are all similar?" Do the first one. Save it. Save it again with another file name and then edit it, reflecting any minor differences between the last job and the current one. You can keep using this method indefinitely of course and sometimes it will be quicker than using the 'multiple room facility'. You can even create your own 'Quick selection' file collection.


No. 4 "Need to create a new 'compound material'?" The quickest way may be to 'clone' an existing one and then edit it. Don't forget to make sure the description accurately reflects the changes though.


No. 5 "Can't find your city or town on the world maps?" Simple! Find out the latitude and longitude co-ordinates (maybe from a road map or an atlas), click on the database edit button and just type them in. Alternatively, if you can visualise the location precisely by looking at the maps (zooming in will help), simply 'right click' your Mouse cursor over your chosen location. If you don't know the precise meteorological data applicable to your new geographic location then look for the nearest city to your chosen location. If it isn't too far away and it is similarly located relative to the coast and has a similar altitude then its weather data is unlikely to be very different. You can always improve accuracy later after doing some more research.


No. 6 "You've made some database edits and now can't find them?" Maybe they're left behind on another computer (Mistral doesn't mind how many computers you install its programs to providing they all belong to the same individual, firm or branch of a firm [only multi-branch firms need multiple licences and even these are greatly discounted]).

If you want to copy modified databases from one computer's hard drive to another then make sure you copy all of the files that were changed at the same time. Use Windows Explorer or a similar file management program to check for precise file 'save' times. Files that were saved within seconds of each other were saved automatically as sets and must be copied as sets otherwise they won't work properly. You might even have to re-install your Mistral program(s) if this happens but don't worry, the worst that can happen is you might lose some of your database edits.


No. 7 "You weren't expecting the 'Peak Load' to be so early or late in the day?" Are you sure you've got the building's 'Orientation' correctly set? It can make a very large difference - particularly when a low, early morning and mid-season sun is shining straight through an east facing window for example. If the building isn't built yet - persuade the architect to move the windows, shade them or even to 'rotate' the entire building if feasible.


No. 8 "My client is an architect and he wants to see results for his building design in several cities all over the world. It's going to take ages!" No it isn't! Simply do the project once, save it and then save it again with a new file name. Relocate the project and then re-save it. You can do that as many times as you want. The program will automatically re-compute everything that it needs to! Make sure you match your client's 'Orientation' requirements for each new location though!


No. 9 "My heating load looks a bit low!" Have you temporarily checked out the 'Personnel' and Miscellaneous Loads? Possibly the 'Lighting' Load as well? You need to find 'worst case' conditions for heating and that means with as many 'unreliable' sources of energy excluded as possible. Switching back to A/C calculation mode will automatically switch these temporarily excluded loads back in; so don't worry about making any mistakes.


No. 10 "Why is there a facility for changing the colour of my building? What difference could it possibly make?" On a relatively small building of say under 750 cubic metres (26,500 cubic feet) then admittedly, not much. See the difference though between a dark colour painted rendered wall and a white wall 25 metres long by 5 metres high. The difference might cost you the job at quotation time, or worse, if the problem was the other way around - get you the job when you'd have been better off not getting it!


No. 11 "It takes too long to keep clicking on 'wall labels'!" Then 'draw' a 'frame' around all of them at once by clicking and holding down your left Mouse button whilst 'dragging and dropping' the cursor. Now ALL the wall labels will be set for materials and features selections in one go! (See Tip of the Day No. 2 as well about another and similar shortcut using the Ctrl key.)


No. 12 "I don't want to tell my client everything about the calculation right now because I suspect he'll 'feed' the information to my competitor. However I still want to impress him with a report with some details." Simple! Click on 'Print' and then on 'Print to File'. This will send what is known as a RTF (Rich Text File) to any directory location of your choice. From there you can retrieve (open it) using any Windows based word processor and make any edits you want. (Don't distort any mathematical results though. That would be dishonest!).


No. 13 "Why not add colour and interest to your quotations by inserting drawings of the RAC equipment you've selected or Bar Graphs and photographs?" It could win you the order! It's easy to do. Just click on 'Save Current Chart to File' when the image you want is open. This will send the graphical image to any directory location of your choice. From there you can retrieve (open it) using any Windows based word processor and include it in the body of your text.


No. 14 "Mistral is very strict about who gets to use its software." That means you, as an authorised and licenced user, get to use the best researched and highest quality tools for your job at the lowest possible prices. Your existing Mistral software licence also entitles you to substantial discounts off additional programs and program upgrades (program updates are free of charge). Keep in touch with Mistral frequently to see what's new. After all, Mistral only succeeds because it saves time and money for people like you!


No. 15 "Can't find the cooler or condenser or compressor etc. in Mistral's product selection systems?" Please don't grumble at us! We have very strict rules and will not publish manufacturers' data:- 1) without their permission and 2) unless they check and approve it for release. That way you can be certain it is right. If the product you would like to see isn't there then call that manufacturer or their distributor or tell their representative and recommend that they contact us straight away. That way, everyone helps each other and everyone gets what they need.


No. 16 "Trawling through 'Help' pages is an irksome task. You search for ages and then never find what you're looking for!" Here's a real jewel of a tip! Press the F1 key whilst the form you're having difficulty with is still displayed on your screen. Mistral's programs are usually smart enough to do the searching for you and find the right help page for you.

If that doesn't work, simply hit the 'Enter' (or 'Return' key as it's sometimes called). Mistral has built in lots of 'intelligent logic' routines that work behind the scenes and actually try to figure out what it is you want to do next. Try it! It's often always right!


No. 17 "Clearly most world locations (with the possible exception of places like Singapore) don't have almost constant temperature and humidity conditions through night and day and for every day of the year. I know we should design for 'worst cases' and Mistral's programs reveal these but how can I find out how much energy my client might need at say 3am on the 10th September?" Simple! Just reset the clock to the desired time and the program will instantly re-compute, everything! Also, try clicking on the 'Review' button (on the top menu bar) and then on 'Annual Energy Profiles'. Lots of options will be displayed and these will tell you practically everything there is to know about the project's hourly, daily, weekly and monthly energy requirements. Be careful though, large projects involve many BILLIONS of automatic calculations before distilling the results into simple 'plain English' and understandable results. Therefore some computers might require a few minutes to do the job.


No. 18 "Why does my program always start with the time and date for a new project set at mid-day on the 21st June?" Your program copy might, but in Australia and other countries in the Southern Hemisphere the program 'defaults' to mid-day on the 21st December. The reason is that at these times and dates results are most likely to be for the highest cooling load requirements in their respective regions. Try clicking though on the 'Search for highest month' and then on the 'Search for highest hour' buttons on the top menu bar. Even the most innocuous looking structures can sometimes reveal quite unexpected results at different times of the day.


No. 19 "Mistral seems to launch program Upgrades about every 30 months or so. Will I save money by skipping the next one?" No! You won't and why should you get the benefit of missed Upgrades that your contemporaries (or even your competitors!) are paying for? Mistral produces Upgrades because they are necessary; usually to take advantage of relentlessly changing computing technology but Mistral only offers Upgrade discounts to Registered Licencees that have previously Upgraded. Mistral runs a business just like you do. Salaries, taxes, equipment and running costs have to be funded just the same as in your business.


No. 20 "I find it difficult drawing walls accurately on the screen" Try zooming in by clicking the magnifying glass at top left of the room design form. Also try right Mouse Button clicking with your cursor focused over a wall node (end point). A form pops up which allows you to enter a wall length to an accuracy of 1 millimetre!


No. 21 "I can't join a wall halfway along the adjacent room's wall length!" You need a node on the wall of the adjacent room at the point you want the new wall to join it. Come out of the room design form by cancelling, return to the adjacent room by clicking in the rooms list menu then open the rooms design form again. Click on the 'Add Node' button at top left of the room design form and click on the wall of the adjacent room where you want the wall of the other room to join it.


No. 22 "My wall material changes within the same length and part of it is internal as well" Simply add wall nodes (by clicking on the 'Add Wall' node button at top left of the room design form). You can then treat each section totally separately with different materials, colours and ambient and solar exposure.


No. 23 "I want to put a half circular wall plan at the end of my room. How do I do that?" Currently this facility doesn't exist in the program but you can draw a series of short walls arranged like the old British 'Thruppenny Bit' 12 sided coin. Easy to do by first drawing a single straight wall and then introducing as many additional wall nodes roughly equally spaced along the length of the wall. Then 'drag & drop' them into finer position using the Mouse Cursor and left Mouse Button. Presumably each section will be of the same construction material so click each node whilst holding down the Ctrl key then you can enter material details for all of the sections simultaneously. With enough sections it is possible to achieve sufficient accuracy for all practical purposes as a true curve.


No. 24 "Multiple room project with lots of similarly constructed rooms?" Save time by completing the first room and then copying it. You can then 'drag and drop' each copied room into position by holding down the 'Shift' key at the same time as the left Mouse button. Don't forget though! Each copied room will include ALL of the features of the original room; including construction materials, doors, windows etc., although these rooms can each of course be individually edited later.


No. 25 Don't forget to 'Right Click' with your mouse to reveal more options.

No. 26 Hitting the F1 key will bring up dynamically linked and 'focused' Help pages.

No. 27 Stuck? Then hit 'Return'. Mistral's programs 'auto-navigate' to the next logical procedure.

COLDWIND and COLDWIND Pro tips (scroll up for AIRWIND tips)

No. 1 "Need a simple room design fast?" Instead of starting from scratch, click on
'Quick Selection' when starting a new session. Choose a grid size coldroom, select the temperatures and product and let 'COLDWIND' make all the rest of the decisions for you.
If the room dimensions aren't right it's simple to edit them and everything else will automatically be adjusted accordingly.


No. 2 "Complicated room with lots of walls but some of them share common features?" Save time selecting the features that are common to each wall by holding down the Ctrl key at the same time as left Mouse clicking on the wall labels. You can then go on to choose materials, doors, windows etc. for all of the walls you have selected, all in one go! (See Tip of the Day No. 11 as well about another and similar shortcut involving 'dragging and dropping' with your Mouse cursor)


No. 3 "If you select Ventilation and enter a figure you are introducing air into the room." Unless you have a powered extract system as well then you have got 'positive air pressure' in your room. In this situation it isn't wise to select Infiltration as well or you might risk 'over-engineering' the job.


No. 4 "Got two or three jobs that are all similar?" Do the first one. Save it. Save it again with another file name and then edit it, reflecting any minor differences between the last job and the current one. You can keep using this method indefinitely of course and sometimes it will be quicker than using the 'multiple room facility'. You can even create your own 'Quick selection' file collection.

You might even have to re-install your Mistral program(s) if this happens but don't worry, the worst that can happen is you might lose some of your database edits.


No. 8 "Getting an unexpectedly large product load in your 'COLDWIND' calculation?" Perhaps you were only planning to design a chill room but have entered the room design temperature below the freezing temperature of the product. This will substantially increase the product load (sometimes by ten times or more) due to the introduction of latent energy exchanges. Try increasing the room design temperature slightly or use the 'higher product exit temperature' facility. But only if you are certain this is what you really want to do.


No. 9 "Want to add a food product to the program's database but the program keeps asking you for 'Respiration Heat', even when you know it doesn't apply in this case?" The reason is that you're trying to put your new food product data in the wrong product group. Only Fruit and Vegetable food categories need Respiration Heat data so if you're adding data for meat or fish for example then make sure you put it under the correct heading. It's good housekeeping anyway!


No. 10 "You weren't expecting the 'Peak Load' to be so early or late in the day?" Are you sure you've got the building's 'Orientation' correctly set? It can make a very large difference - particularly when a low, early morning and mid-season sun is shining straight through an east facing window for example. If the building isn't built yet - persuade the architect to move the windows, shade them or even to 'rotate' the entire building if feasible.

Then 'draw' a 'frame' around all of them at once by clicking and holding down your left Mouse button whilst 'dragging and dropping' the cursor. Now ALL the wall labels will be set for materials and features selections in one go! (See Tip of the Day No. 2 as well about another and similar shortcut using the Ctrl key.)


No. 12 "My client is an architect and he wants to see results for his building design in several cities all over the world. It's going to take ages!" No it isn't! Simply do the project once, save it and then save it again with a new file name. Relocate the project and then re-save it. You can do that as many times as you want. The program will automatically re-compute everything that it needs to! Make sure you match your client's 'Orientation' requirements for each new location though!

You need to find 'worst case' conditions for heating and that means with as many 'unreliable' sources of energy excluded as possible. Switching back to A/C calculation mode will automatically switch these temporarily excluded loads back in; so don't worry about making any mistakes.


No. 14 "I've put product in to my cold room at lower than room design temperature but the program doesn't return a 'negative' cooling load. Why not?" Think about it. If Mistral didn't 'cancel' such negative cooling loads you might end up selecting refrigeration equipment that was undersized because part of its load was being taken by the product acting as a 'heat sink'. What would happen when the product reached design temperature? The 'heat sink' would no longer be there to cope with other sources of energy such as through the structure and from air changes! There are ways to over-ride this safety feature though. For 'Tempering Rooms' for example. You'll need to contact us to obtain a 'Special Feature Code'.


No. 15 "Why is there a facility for changing the colour of my building? What difference could it possibly make?" On a relatively small building of say under 750 cubic metres (26,500 cubic feet) then admittedly, not much. See the difference though between a dark colour painted rendered wall and a white wall 25 metres long by 5 metres high. The difference might cost you the job at quotation time, or worse, if the problem was the other way around - get you the job when you'd have been better off not getting it!

Just click on 'Save Current Chart to File' when the image you want is open. This will send the graphical image to any directory location of your choice. From there you can retrieve (open it) using any Windows based word processor and include it in the body of your text.


No. 18 "Unless you're 'Blast Chilling' or 'Blast Freezing' don't try to reduce the temperature of food products faster than necessary." If food product, which is already at a safe temperature, is to be introduced into a storage or holding room for longer term storage then don't enter temperature reduction times that are too fast (say under 24 hours for a further 5 Kelvin or 9 Rankine reduction). Unless your customer has good reason and is aware of the implications or a consultant is insisting upon it, unnecessarily short temperature reduction times add enormously to the energy requirements of the cooling equipment (both capital costs and power requirements) without adding anything to food safety. Also, unless temperature differentials between cooler air off temperature and product design temperature are carefully chosen and air distribution systems scientifically well managed the product will not give up all its energy in extremely reduced times anyway.


No. 19 "Mistral is very strict about who gets to use its software." That means you, as an authorised and licenced user, get to use the best researched and highest quality tools for your job at the lowest possible prices. Your existing Mistral software licence also entitles you to substantial discounts off additional programs and program upgrades (program updates are free of charge).

No. 22 "I entered all my food product details but then I had to change the room size because I'd made a mistake. The program forced me to enter some of the details again. Why?" Well, the program didn't know quite how many mistakes you had made or, simply, might have made! To be on the safe side it didn't assume that you wanted the same product turnover, for example, as in the original room size you chose. Most programs wouldn't be so refined but then Mistral has a reputation for protecting its users' interests. Absolutely no one is immune from mistakes and the consequences can be much more expensive than just a few extra key presses!


No. 23 "Clearly most world locations (with the possible exception of places like Singapore) don't have almost constant temperature and humidity conditions through night and day and for every day of the year. I know we should design for 'worst cases' and Mistral's programs reveal these but how can I find out how much energy my client might need at say 3am on the 10th September?" Simple!

Easy to do by first drawing a single straight wall and then introducing as many additional wall nodes roughly equally spaced along the length of the wall.

With enough sections it is possible to achieve sufficient accuracy for all practical purposes as a true curve.


No. 30 "The refrigeration load for the chiller in my dual compartment coldroom should be reduced because it is next to a freezer. Can I calculate with the partition wall at a different temperature to ambient." Yes, you can. Simply click on the 'Wall Exposure' button and then check 'Other Temperature'. Be careful though. What would happen to product in the Chiller if the Freezer system fails?


No. 31 "I've put a fork lift truck into my coldroom and the load has gone up enormously!" Make sure you apply a realistic 'Power Factor'. It isn't possible to either create or destroy energy, only to move it or change its state, so theoretically every Watt of power the batteries on an electric fork lift truck are capable of producing must end up as heat and if the machine is in the coldroom all of the time then this heat will also be in the coldroom. However, does the machine spend all of its time in the coldroom? Unlikely if it is used for moving product in and out. Also the rated power of the machine only applies when it is working at maximum output. That is when it is lifting at its maximum capacity. Most of the time it isn't operating in this mode (travelling or lowering loads use significantly less power). A power factor of from 15% to 20% is therefore usually quite sufficient for a fork lift truck.


No. 32 "Why when I enter a fruit or vegetable into a chill room does the program require me to enter 'Total weight stored' in addition to turnover?" Fruit & Vegetables are live products (unless they've been boiled or frozen) so they 'breathe' and in the process of breaking down carbon dioxide generates heat. The heat from the total amount of product stored ends up in the chill room. With other products such as meat or fish 'Respiration Heat doesn't apply.


No. 33 "Multiple room project with lots of similarly constructed rooms?" Save time by completing the first room and then copying it. You can then ‘drag and drop’ each copied room into position by holding down the ‘Shift’ key at the same time as the left Mouse button. Don’t forget though! Each copied room will include ALL of the features of the original room; including construction materials, doors, windows etc., although these rooms can each of course be individually edited later.
