摘要： A CO2 cycle system having a variable capacity compressor is controlled even when the refrigerant delivery capacity of the variable capacity compressor changes. When the refrigerant delivery capacity of the variable capacity compressor decreases, the aperture of an electric expansion valve is fixed for a predetermined time To. When the refrigerant delivery capacity has not changed, the aperture of the electric expansion valve is controlled so that the refrigerant temperature and pressure on the outlet side of a system heat exchanger change along an optimal control line. As a result, because the refrigerant delivery capacity Qd of the compressor is controlled in correspondence with the intake pressure Ps, i.e., the pressure on the side of the evaporator, without being influenced by control of the expansion valve side, the CO2 cycle system can be adequately controlled.

摘要： A modulator in a coolant recirculation line for a refrigerating apparatus. The modulator is used for storing an excess amount of the coolant recirculated in the system. The modulator has a space extending vertically, upward and a bottom end connected to the recirculating line at a position downstream of a condenser, in such a manner that only a part of the coolant passed through the condenser is introduced into the modulator to compensate for variations in the amount of coolant needed for recirculation in the system. The modulator can be arranged in the middle of the heat exchanger, and defines therein a boundary between the liquid phase and the gas phase, for a separation of the gas from the coolant, so that the portion of the heat exchanger downstream of the modulator can operate as a super cooler.

摘要： In an ejector refrigerant cycle, even if refrigerant is super-heated in an evaporator, super-heated gas refrigerant does not directly flow into a gas-liquid separator, so that boiling of refrigerant does not occur in the gas-liquid separator due to evaporation of refrigerant in the gas-liquid separator. When an equivalent inner diameter (D) of a tank body of the gas-liquid separator is set in a range of 2 cm–6 cm, and when a ratio of a vertical dimension (H) of the tank body to the equivalent inner diameter (D) thereof is larger than 1, a wall thickness of the tank body can be reduced while gas-liquid separation performance in the gas-liquid separator can be improved.

摘要： In a vehicle air conditioner with a heat pump refrigerant cycle, an interior heat exchanger of the refrigerant cycle is disposed in an air conditioning case to heat air in a heating operation and to cool air in a cooling operation. Further, a cooling heat exchanger for cooling air by evaporating the refrigerant is disposed so that a part of refrigerant circulating in the refrigerant cycle flows into the cooling heat exchanger at least in the heating operation. In addition, a decompression unit for decompressing refrigerant flowing to the cooling heat exchanger is disposed, and the decompression unit is opened even in the cooling operation. Accordingly, dehumidifying capacity of the air conditioner can be improved while the refrigerant cycle has a simple structure.

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 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.
