Title:
TWO-STAGE PRESSURE BUILDUP REFRIGERATION CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/004987
Kind Code:
A1
Abstract:
Disclosed is a two-stage pressure buildup refrigeration cycle system which includes a higher-stage compressor mechanism (11a) and a lower-stage compressor mechanism (12a), the refrigerant delivery capacities of which are independently controllable. The refrigerant delivery capacity of the lower-stage compressor mechanism (12a) is determined on the basis of an outside air temperature (Tam), an air temperature (Tfr), and a temperature setting (Tset). The refrigerant delivery capacity of the higher-stage compressor mechanism (11a) is determined based on the determined refrigerant delivery capacity of the lower-stage compressor mechanism (12a) so that the effective capacity ratio is equal to or greater than one and equal to or less than three. This simplified construction and control can provide an improved COP for the two-stage pressure buildup refrigeration cycle system.
