摘要： PURPOSE:To produce cold water efficiently using waste heat and prevent environmental pollution by operating adsorption type freezer with the use of the hot water coming from a waste heat recovery hot water system via the waste heat recoverer of a internal combustion engine and the condenser of a compression type freezer, as a regenerative heat source. CONSTITUTION:The waste heat generated by the operation of an internal combustion engine 1 is recovered in the hot water in a waste heat recovery hot water system H by way of the path in a waste heat recoverer 6 consisting of a jacket heat exchanger 3 and an exhaust gas heating exchanger 5. Also by the operation of a compression type freezer C, the heat generated in a condenser 8 is collected by the hot water in the waste heat recovery hot water system H by way of the path in the heat exchanger part 15 in the condenser 8 and is supplied to an adsorption type freezer A. If the heat generated in the condenser 8 cannot be removed only by the water in the heat exchanger 15, the heat supplied to a cooling tower 17a. The hot water in the waste heat recovery hot water system H flows to the adsorption type freezer A and in a regeneration pot to regenerate the adsorbent. The cool water in a cool water path Wb flows to a heat exchanger 34 in a cool water system W together with the cool water produced in the evaporator 10 in the compression type freezer C, and is utilized for air conditioning.
