Title:
AIR CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/142352
Kind Code:
A1
Abstract:
The adsorption performance of an adsorption refrigerating machine is ameliorated regardless of the engine load when the cooling capacity of a steam compression refrigerating machine is improved by concurrently using an adsorption refrigerating machine. An adsorption refrigerating machine (11) is equipped with an adsorber (12), which adsorbs/desorbs a medium by cooling/heating, and has: a cold storage mode in which a medium adsorbed to the adsorber (12) is desorbed by heating the adsorber (12), is condensed and liquefied in a condenser (14), and is retained in an evaporator (15); and a cold releasing mode in which a medium is adsorbed to the adsorber (12) by cooling the adsorber (12) resulting in the medium to evaporate in the evaporator (15). The evaporator (15) of the adsorption refrigerating machine (11) is incorporated into the refrigerant circuit (compressor (6), condenser (7), expansion valve (8), and evaporator (9)) of a steam compression refrigerating machine (5), and is configured to cool the refrigerant when the medium evaporates. The adsorber (12) is heated by introducing the cooling water of an engine (1) to a heat exchanging pipe (12b) by means of a valve (19), and the adsorber (12) is cooled by means of a cooling fan (17).
