Fonctionnement

Vapor-compression refrigeration with R22: scroll compressor draws low-T low-P vapor from evaporator, compresses to high-T high-P, condenser rejects heat (10,000 m3/h cooling air), TXV expands liquid into evaporator, where ambient air (4,500 m3/h, 3,000 Pa) is chilled to set-point and delivered to load.
