'BORAWIND' Grid sized Blast Chiller/Freezer design selections are 'dynamic' in that they may be edited to precisely match individual 'End User' project requirements.
Whilst Mistral can guarantee that 'BORAWIND' calculation resultant Refrigeration Loads are accurate, great care should nonetheless be taken to ensure that input design parameters match the sometimes onerous conditions or expectations from the End User. Heeding the following short list of recommendations is therefore strenuously advised. Mistral cannot and does not accept any responsibility for the consequences of design failure due to inexperienced engineers' mistakes.
1) Ensure Mistral's accepted industry Design Standard of 90 minute product temperature pulldown time is what is required. The program does provide the opportunity to adjust this. Much below 90 minutes though and can you be sure the product will give up its energy in the time allowed?
2) 'BORAWIND' 'Pre-engineered' project designs open with Ambient Air temperature set at 32°C (89.6°F). Ensure this matches the requirement for your region. Ambient Air temperature can easily be changed for an individual project.
3) 'BORAWIND' 'Pre-engineered' project designs can be opened with chamber (room) floor plans set to default to either interior or exterior dimensions. The option to switch 'BORAWIND' floor plan default is simple to change via this button 
found in 'BORAWIND''s 'Settings' Program Group Form.
Ensure the correct dimensioning method for the project is set. The difference this can make for Blast Freezers in particular can be very large!
4) Cooler defrost cycle (Running Loads) are NOT included. It is not normal to run a defrost operation during Blast Chiller or Blast Freezer operating time.
5) There can be a valid case for claiming that if the Primary Refrigeration Load can meet the Latent duty requirement then Product Sensible gains can safely be ignored. Particularly if Latent load exceeds Sensible load by a
considerable margin, more than double for example. However consideration must also be given to the amount of time taken for Sensible loads to be met, before remaining time available for the refrigeration system to remove Latent energy.
Another consideration is that where Blast Freezing operations are repeated 'end to end' throughout a daily production period then structural exposure to ambient temperature can safely be at least partially mitigated.
Removing Sensible Product gains from the calculation from operations following the first of the day, although not directly related can nonetheless be reasonably expected to achieve this.
If you are comfortable with this hypothesis then simply select the Remove Sensible Heat Gains
option displayed in the
Product Selection menus.
6) 'BORAWIND' makes no provision for Evaporator (Cooler) Air Off temperatures or Air Velocities. It is expected that 'BORAWIND' users will already have sufficient experience in this area so as to make practical choices.
Remember:- Food products such as mashed potato are notoriously difficult to Blast Chill effectively, due to this products' self insulating properties.
CAUTION! Care should be taken when opening a 'Grid Size' design and then making changes to it, to remember to also edit the Reference description to match any changed design parameters.
