FSS3 - FRASCOLD SELECTION SOFTWARE v1.6


Find hereinafter the details of the last FSS3 Frascold Selection Software release.

ALL SOFTWARE:
· COP now it’s COP/EER and it’s calculated as cooling capacity at the evaporator / power consumption, for USA [BTU/h / W]
· Modified standard IP unit for volume (oil charge) from in3 to fl.oz

RECIPROCATING COMPRESSORS:
· RSH: added RSH unloader calculation for all available models.
· C6: added the new open reciprocating compressors C6 for H(C)FC and Ammonia
