Air-conditioner with refrigerator

Abstract

Abstract PURPOSE:To devise to drive a refrigerator independently as well as to keep its refrigerating effect free from the influence of the driving state of a car in a titled unit for automobile by switching over electromagnetic valves provided on a refrigerator entrance pipe and a bypass valve properly and selectively. CONSTITUTION:A refrigerator entrance pipe 7 is connected with the preceding stage of an expannsion valve 3 on the side of an air-conditioner, and on the way of this entrance pipe 7, a bypass pipe 13 is provided to return refrigerant to a compressor 1. On the preceding stage of an expansion valve 3 of an air-conditioning circuit, the bypass pipe 13, and the rfrigerator entrance pipe 7, electromagnetic valves 15, 16, and 17 are respectively provided to be selectively switched over. For operating an air-conditioner and a refrigerator simultaneously, swithes 19 and 21 are put to ON to release electromagnetic valves 15 and 17, and refrigerant is given to sides of the expansion valve 3 and a throttle 8. Meanwhile, for refrigerating the contents of the refrigerator quickly, only the electromagnetic valve 17 is put to OFF, and electomagnetic valves 16 and 17 are put to ON for operating the bypass pipe 13.
