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.
