摘要： An air conditioner has a refrigeration circuit formed by sequentially connecting a compressor 1, a condenser 2, an electronic expansion valve 4 and an evaporator 7 by pipes (6, 10). A compressor bypass pipe 12 is provided to connect an outlet of the evaporator 7 with an inlet of the condenser 2. A first on-off valve 11 is located in the bypass pipe 12. The air conditioner is controlled to switch to either a forced circulation operation or a natural circulation operation. In the forced circulation operation, the first on-off valve 11 is closed, the expansion valve 4 is opened to a first degree to allow refrigerant to pass therethrough, and the compressor 1 is operated in a running state. In the natural circulation operation, the first on-off valve 11 is opened, the expansion valve 4 is opened to a second degree, different from the first degree, to allow refrigerant to pass therethrough, and the compressor 1 is stopped.

摘要： A ventilation and air conditioning apparatus for a vehicle includes: a ventilator that sucks air from outside the vehicle; an air conditioner that conditions air inside the vehicle; a duct for fresh outside air that connects the ventilator with the air conditioner so as to supply the air that the ventilator has sucked from outside the vehicle to the air conditioner; and a duct for conditioned air that supplies the conditioned air blown out from the air conditioner to inside the vehicle. The duct for fresh outside air is branched so as to be connected to the duct for conditioned air. With this configuration, even if the operation of the air conditioner is stopped due to, e.g., a leakage of a flammable refrigerant, an amount of ventilation can be secured in the vehicle.

To overcome these drawbacks, the refrigerating and air-conditioning apparatus comprises at least a compressor, a condenser, a pressure reducing device, and an evaporator, and in a refrigerant cycle which uses as a working refrigerant a non-azeotropic refrigerant composed of N kinds (N≧3) of refrigerants and is provided with composition detecting means for detecting the circulating compositions of the non-azeotropic refrigerant, circulating compositions are determined by using (N−2) relations on compositions among a first component to a j-th (2≦j≦N−1) component of the non-azeotropic refrigerant.
