WebFeb 18, 2024 · The liquid receiver stores refrigerant when the system is operating at less than maximum heat load. It is generally designed so that the receiver can hold all of the system charges and still be no more than 80% full. How does a refrigeration receiver work? It is basically a storage vessel designed to hold excess refrigerant not in circulation. Webh = heat of compression (Btu/lb) q = refrigerant circulated (lb/min) Compression Horsepower. Compression horsepower can be expressed as. P = W / 42.4 (2) where. P = compression power (hp) W = compression work (Btu min) Alternatively.
