The present invention relates to a composite freezer, and more particularly, to a composite freezer in which an absorption-type freezer and a vapor compression-type freezer are combined, and which has improved performance and reduced energy consumption. The composite freezer of the present invention is provided with: an absorption-type freezer (10) constituted by a regenerator (11), a condenser (13) having a refrigerant pipe (14') installed thereon, an evaporator (15), an absorber (17) having a refrigerant pipe (14) installed thereon, and a condensing means (18) connecting the refrigerant pipes (14, 14') by means of a refrigerant circulating pipe 20; and a vapor compression-type freezer (40) in which a compressor (41), a condenser (42), a liquid receiver (43), an expansion valve (44), and an evaporator (45) are connected by a refrigerant pipe (46). The condenser (42) is installed within the regenerator (11), a second condenser (47) is installed between the condenser (42) and the liquid receiver (43) of the refrigerant pipe (46), a refrigerant circulating bypass pipe (51) is connected to, and a heat radiating heat exchanger (52) is installed at, the outlet of the refrigerant pipe (14') of the refrigerant circulating pipe (20) and the inlet of the refrigerant pipe (14), a second refrigerant pipe (53) in which a second expansion valve (54) is installed is connected between the liquid receiver (43) and the compressor (41) of the refrigerant pipe (46), a heat absorbing heat exchanger (55) maintaining a heat exchanging relationship with the heat radiating heat exchanger (52) is installed on the second refrigerant pipe (53), a cold water heat exchanger (56) is installed on the evaporator (45), and an evaporating heat exchanger (16) and a cold water circulating pipe (58) are connected. |
