Abstract:
A heat exchanging apparatus in cooperation with a refrigeration system including a compressor, a condenser, an expansion valve, and an evaporator being interconnected by a refrigerant line, the apparatus comprising:a first water line;a second water line;a thermos tank for storing water made of a material capable of keeping the temperature of the water at a constant level, one end of the thermos tank being an inlet in fluid communication with the first water line;a thermostat;a plurality of first heat collecting tanks;a plurality of second heat collecting tanks;a pump for pumping water to the first heat collecting tanks through the first water line; anda drive controller;wherein one of the first heat collecting tanks adjacent to the compressor has the refrigerant line passing therethrough, two ports, at opposite ends of the first heat collecting tank are in fluid communication with the first water line which connects the pump through the thermos tank for forming a loop, one of the second heat collecting tanks adjacent to the condenser has the refrigerant line passing therethrough, one end of each of the second heat collecting tanks is provided as a cold water inlet, and the other end of each of the second heat collecting tanks is provided as an outlet for feeding water to the first water line through the second water line, and the drive controller is electrically connected to the compressor and the thermostat which is electrically connected to the thermos tank so as to measure the temperature of the water for determining whether to stop operation of the pump as compared to a predetermined temperature.
