Title:
TWO-STAGE COMPRESSOR HEAT PUMP CYCLING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/023737
Kind Code:
A1
Abstract:
A two-stage compressor heat pump cycling apparatus using the NH3 heat media, wherein three kinds of heat media including high-temperature, medium-temperature and low-temperature media can be extracted at the same time while stabilizing extraction of the high-temperature heat media. The following configuration is employed for the apparatus. A first heat transfer media flow path (14) is provided in a condenser (13) to generate the high-temperature heat transfer media through latent heat exchange of first heat transfer media a with gas heat media n1 in the condenser, while a second heat transfer media flow path (16) is provided in an evaporator (23) to generate the low-temperature heat transfer media through latent heat exchange of second heat transfer media c with liquid heat media n2 in the evaporator. Further, a first subcooler (15) is interposed between the condenser (13) and an intermediate cooler (18), while a second subcooler (21) is interposed between the intermediate cooler and the evaporator (23), and a third heat transfer media flow path (16) is provided in series with the first subcooler (15) via the second subcooler (21) to generate the medium-temperature heat transfer media through sensible heat exchange of third heat transfer media b with the liquid heat media in the first and second subcoolers.
