PROGRAMS for REFRIGERATION & AIR CONDITIONING PROFESSIONALS by MISTRAL

Mistral program customisation options through 'Special Feature Codes'

Occasionally an unusual application might arise. For example: Exceptionally low room design temperatures or extraordinarily high coldrooms. Extreme and rare design conditions may be beyond the scope of the programs' inherent 'error trap' limits. They will inevitably call upon special knowledge and engineering skills in order to complete a totally successful design. As a safety measure Mistral therefore excludes various extreme inputs when programs are used in their 'default' setting. However, when an engineer is required to work on an unusual design a conscious decision may be made to enter 'Special Feature Codes' that will relax or even bypass certain of the programs' inherent 'dynamic error traps'. The procedure for accessing these 'Special Feature Codes' is described below and also appears under the 'Utils' folder of every Mistral program CD-ROM.

Program users are though warned to use these features with caution and are reminded that Mistral Associates cannot and will not accept liability for the consequences of any design produced using Mistral's intellectual property (software) whether or not the 'Special Feature Codes' were activated.

Special Feature Codes:-

Program		Code		Feature


AIRWIND		MZPP		Relax door and window error trapping on grid
				(permits rooms to have no doors or windows).


AIRWIND		CIWM		Allow very high ambient (above 50ºC/122ºF)


COLDWIND	MZPP		Relax door and window error trapping on grid 		
				(permits rooms to have no doors or windows).


COLDWIND	PATX		Allow large room dimensions (above 100 metres/330’)


COLDWIND	DEKK		Allow ‘negative’ Product gains. 
                                Useful for 'tempering rooms' for example.


COLDWIND	MIRF		Allow room design temperatures down to -99ºC/-146ºF.
 

COLDWIND	EGYH	 	Allow very high room temps (20ºC/68ºF)
 

COLDWIND	WYKX	 	Allow very high coldrooms (50m/164')


COLDWIND	TPWS	 	Allow very low Total Product Weight Stored
                                (applies to Fruit & Vegetable and GP chill rooms only)


COLDWIND	ARCH	        Override Product volume displacement in infiltration rate calculation.
