Title:
HEAT PUMP HOT WATER SUPPLIER
Document Type and Number:
WIPO Patent Application WO/2007/114187
Kind Code:
A1
Abstract:
A heat pump hot water supplier where surplus refrigerant is not produced in a refrigerant circuit, thereby a shortage of suction gas in a rotary compressor is prevented, and where an occurrence of noise near the compressor is suppressed. A refrigerating apparatus (1) has the compressor (21), a first heat exchanger (22), an expansion mechanism (23), a second heat exchanger (24), and a muffler (26). The compressor is of a rotary type and is used to compress the refrigerant. The first heat exchanger exchanges heat between a first fluid and the high-temperature high-pressure refrigerant compressed by the compressor. The expansion mechanism reduces the pressure of the refrigerant condensed in the first heat exchanger. The second heat exchanger exchanges heat between a second fluid and the refrigerant reduced in pressure by the expansion mechanism. The muffler is disposed between the second heat exchanger and the compressor and reduces the pulsation of the flow of the refrigerant.
