Title:
AIR-CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP3219107
Kind Code:
B2
Abstract:
PURPOSE: To improve the operating efficiency of a absorption type refrigerating machine by cooling the cleaning coil of an outer air-conditioning machine by a heat pump.
CONSTITUTION: Cold water, coming from a main supply tube 15 which supplies the cold water from an absorption type refrigerating machine 11 into a main air-conditioning machine 13, passes through a first pipeline 45 to enter the evaporator 21 of an outer air-conditioning machine 27 and is cooled by heat exchange, then, enters a cleaning coil 35 through a second pipeline 47. Then, heat exchange is effected in the cleaning coil 35 and, thereafter, is circulated again into the main supply tube 15 through a third pipeline 149. On the other hand, hot-water, coming from a main returning pipe 17, connecting the main air-conditioning machine 13 to the absorption type refrigerating machine 11, enters the condenser 25 of the outer air-conditioning machine 27 and is heated, then, enters a heating coil 33 through a fifth pipeline 53. Thereafter, heat exchange is effected in the returning pipeline 17 through a sixth pipeline 55. According to this method, the operating efficiency of the absorption type refrigerating machine 11 is improved.
