摘要： In a vehicle air conditioner, an interior heat exchanger of a heat pump refrigerant cycle is disposed in an air conditioning case to heat and cool air passing therethrough. The air conditioning case has therein a bypass passage through which air flows to a downstream side while bypassing the interior heat exchanger. In a defogging mode, air mainly passing through the bypass passage is blown toward a windshield of the passenger compartment, and air mainly passing through the interior heat exchanger is blown toward a lower side in the passenger compartment. Accordingly, even by setting the heating capacity of the interior heat exchanger at a maximum degree, it can restrict a windshield from being fogged in the defogging mode.

摘要： In a refrigerant cycle system, refrigerant compressed in a first compressor is cooled and condensed in a radiator, and refrigerant from the radiator branches into main-flow refrigerant and supplementary-flow refrigerant. The main-flow refrigerant is decompressed in an expansion unit while expansion energy of the main-flow refrigerant is converted to mechanical energy. Thus, the enthalpy of the main-flow refrigerant is reduced along an isentropic curve. Therefore, even when the pressure within the evaporator increases, refrigerating effect is prevented from being greatly reduced in the refrigerant cycle system. Further, refrigerant flowing into the radiator is compressed using the converted mechanical energy. Thus, coefficient of performance of the refrigerant cycle system is improved.

摘要： A heat pump cycle system which can switches cooling operation and heating operation for a compartment includes a first inside heat exchanger and a second inside heat exchanger disposed in an air conditioning case. The first inside heat exchanger is disposed in the air conditioning case at a downstream air side of the second inside heat exchanger, while being arranged in line in a flow direction of refrigerant. The first inside heat exchanger is upstream from the second inside heat exchanger in the flow direction of refrigerant during the heating operation. In the heat pump cycle system, an expansion valve is controlled so that coefficient of performance in each operation becomes approximately maximum. Thus, during the heating operation of the heat pump cycle system, a lower limit temperature of air blown from the inside heat exchangers can be increased so that temperature of air blown into the compartment is increased, while the coefficient of performance is improved.

摘要： A refrigerating system of vapor compression type operating at a super critical area, while obtaining an increased efficiency. The refrigerating system includes a pressure control means for controlling the temperature and the pressure at the outlet of a heat emitter. The pressure control valve responds to a pressure difference between the inlet pressure of the refrigerant to the pressure control valve and the pressure in an outwardly sealed chamber in which the refrigerant is filled such that, with respect to the volume of the chamber under closed condition of the pressure control valve, a density of the refrigerant is in a range between a density of a saturated liquid at a temperature of 0.degree. C. and a density at the critical point of the refrigerant. As a result, the pressure and the temperature at the outlet of the heat emitter is controlled substantially along the optimum control line .eta.max, resulting in an effective execution of a refrigerating cycle at the critical area.

摘要： In a refrigeration cycle device for a vehicle, a weak-inflammability refrigerant that does not ignite at a high-temperature heat source mounted in an engine compartment of the vehicle in a refrigerant single state is circulated in a refrigerant cycle. The refrigerant cycle includes a compressor for compressing and discharging the refrigerant. The compressor includes an oil separator that is located at a refrigerant discharge side of the compressor to separate a lubrication oil from the refrigerant and to return the separated lubrication oil to an interior of the compressor, a shutting portion configured to shut a reverse flow of the refrigerant at a refrigerant suction side of the compressor, and a driving portion located to drive the shutting portion. Furthermore, the driving portion causes the shutting portion to shut the reverse flow of the refrigerant when the refrigerant cycle is damaged.
