ABSTRACT:
An economized refrigerant vapor compression system (10) for water heating includes a refrigerant compression device (20), a refrigerant-to-water heat exchanger (30), an economizer heat exchanger (60), an evaporator (40) and a refrigerant circuit (70) providing a first flow path (OA,70B,70C,70D) connecting the compression device (20), the refrigerant-to-liquid heat exchanger (30), the economizer heat exchanger (60) and the evaporator (40) in refrigerant circulation flow communication and a second flow path (70E) connecting the first flow path (62) through the economizer heat exchanger (60) to the compression device (20). The economizer heat exchanger (60) has a first pass (62) for receiving a first portion of the refrigerant having traversed the refrigerant-to-liquid heat exchanger and a second pass (64) for receiving a second portion of the refrigerant having traversed the refrigerant-to-liquid heat exchanger. The refrigerant system (10) has a bypass unloading branch (70F) with a c pass flow control device (92) connecting economizer (70E) and suction (OD) refrigerant lines for providing additional capacity adjustment.
