The gas air conditioner feed water temperature control unit null compressor of the CO2

摘要

PROBLEM TO BE SOLVED: To provide a heat pump system that can be operated in a wide range of conditions by executing heat exchange via an antifreeze solution and controlling the temperature of water fed to a gas cooler by the fresh air and cooling water when the water supply temperature rises as a method for lowering the temperature of cooling water supplied to the gas cooler.;SOLUTION: A heat pump composes a refrigeration cycle by equipping a compressor 2, the gas cooler 3, an expansion valve 4, and an air heat exchanger (evaporator) 5, and supplies cooling water to the gas cooler 3 for cooling the refrigerant. In the heat pump, water supply piping (cooling water line) (q) for supplying water to the gas cooler 3 has a water supply cooler 9 that indirectly exchanges heat with an antifreeze solution with the antifreeze solution as a refrigerant and cools supplied water (w), integrally provides an antifreeze solution cooler 10 for cooling the antifreeze solution with the air heat exchanger 5, thus adjusting the amount of heat exchange between the supplied water (w) and the antifreeze solution.;COPYRIGHT: (C)2006,JPO&NCIPI
