COMPUTER SOFTWARE for REFRIGERATION and AIR CONDITIONING PROFESSIONALS from MISTRAL.

Mistral software is designed to be as simple to use as is possible with a computer. Programs follow very closely the process that an engineer will use when doing the job manually. In other words programs that operate in the same way we were all taught and thus learned to think. The advantage with Mistral though is that when inevitable mistakes are made (and very few of us can claim not to have suddenly included an Imperial factor or unit whilst in the middle of an SI based calculation!) then the program will spot them and even recommend appropriate corrections. Rich with colourful graphics, totally error trapped, menu and icon driven wherever possible, Mistral software is both intuitive and a pleasure to use.

All programs have built-in 'intelligent logic' whereby they will not ask unnecessary questions. They even propose solutions whilst running by anticipating what you are going to do next! No need for refrigeration manuals and tables; all the factors and data needed are already built in. The collection of books and manuals alone containing this data would cost far more than the programs. Presentation quality printed reports, essential these days for securing orders, are automatically produced. All this takes place without inhibiting the seasoned engineer or daunting the novice. But just because Mistral's superior programs are the easiest to operate doesn't limit their usefulness. These are the most complete, powerful and professional programs you will ever find for the job - anywhere!

Mistral Freeware

As an introduction to showing just how Mistral's easy to use software can help every refrigeration or air conditioning business listed below are some powerful programs that are available entirely free! There inclusion here paid for by Mistral itself along with a group of Mistral's leading Sponsors and whose names or products are featured in the programs.

Please be aware that all MISTRAL software is dedicated to specific territorial areas of the world. Although all western and most other countries are supported, due to unacceptable political copyright and intellectual property rights issues, certain countries, such as India and The People's Republic of China, are not supported.

Mistral may choose to not send you free code!
It is a sad fact but a few people do not understand that the production plus the need for constant maintenance of computer software involves time, equipment, plus overheads and therefore money. Mistral's FREEWARE programs are offered for bona-fide and deserving individuals and organisations as a gesture of goodwill and of course as a promotion or 'shop window' of other products that Mistral markets for sale. FREEWARE, as its name suggests is offered freely but this does not mean that it did not cost money to develop and continues costing money to maintain, it just means that someone else met those costs. Mistral maintains a database of past abusers of any of its products and therefore reserves the right to not forward the computer code that is its copyrighted intellectual property to some applicants. No correspondence will be entered into in this event.

'Metwind' is a cutting edge program that automatically finds and retrieves meteorological data for tens of thousands of principal world locations. For practically every country in the world! Many companies charge a small fortune for this data and Mistral is now not only offering it to everyone in the refrigeration & air conditioning industry for free, but also with an astonishingly easy to use and imaginative user interface. Also, for those looking for evidence of Global Warming, this program will help provide research or comment with authority!

Although a stand alone program providing indispensable data when run independently, 'Metwind' also automatically loads weather data to other software, plus insolation factors and solar azimuth and declination angles at 15 minute intervals for the entire year for any world location within a 500 metre radius! Thus when used with Airwind or Cellwind for example, providing automatic solar primary and secondary radiation and shading calculations for any construction of any shape or complexity.

'RAC Product Selector' Hundreds of thousands of refrigeration and air conditioning products, from the majority of Europe's leading manufacturers*, available for instant, accurate and automatic selection. Duties properly and precisely corrected to entered design conditions. Cooler duties for example properly corrected and balanced against selected and matched condensing units, even from different manufacturers or suppliers! Selected products automatically link to individual photographs and in most cases, individually created, scale and dimensioned line drawings. Importantly and uniquely, every one of literally millions of database fields have been checked and approved for release by either the manufacturers themselves or by their qualified official agents.

Please appreciate, no one RAC product manufacturer from anywhere in the world either would or could offer you anything even remotely like this program. The advantages it provides for professional RAC users are boundless. The culmination of more than 90 man years of research and programming work. Continuously maintained and updated by a team of qualified, professional engineers - and as all this work is funded by others, access is offered to you absolutely free of charge!

* If you are unable to find your preferred manufacturer's products in this system please contact them and not Mistral. We will not publish proprietary data without both the agreement and approval of the owners of that data. Failing that we suggest you purchase the RAC products your business requires from an alternative manufacturer!

Mistral program manuals, fully colour illustrated, in both Adobe pdf and MS Word doc file format. It must be said that Mistral's strict policy of good programming practice and the celebrated ease with which the intuitive and uniquely 'dynamically error trapped' programs run, make these manuals almost redundant. However the speed and simplicity of operation can disguise the sheer scope of what can be achieved with Mistral programs. These manuals demonstrate features and many 'fast track' routes that sometimes experience alone does not always reveal.
