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： 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 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： 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： In an accumulator cycle, lubricating oil containing polyalkylene glycol (PAG) as a main component is used for a hermetic electric compressor. Lubricating oil mixed with refrigerant (carbon dioxide) can exhibit electric insulation resistance that causes no problems on a practical use. Since PAG has low compatibility with respect to carbon dioxide, a large amount of liquid phase refrigerant is difficult to be sucked into the compressor while being dissolved in lubricating oil. Therefore, the efficiency of the compressor is not lessened.

摘要： A silencer for a refrigeration cycle system is disclosed. The silencer includes a silencing chamber 15a formed in a housing 16, an inlet pipe 20 connected to the housing 16 to allow the refrigerant to flow into the silencing chamber 15a, and an outlet pipe 21 connected to the housing 16 to allow the refrigerant to flow out of the silencing chamber 15a. The direction in which the inlet pipe 20 is connected to the housing 16 and the direction in which the outlet pipe 21 is connected to the housing 16 cross each other. A bend 21c projected into the silencing chamber 15a and curved toward the upstream end 20b of the inlet pipe 20 is formed at the upstream end 21b portion of the outlet pipe 21. The bend 21c is formed with an opening 21d to open the inside part thereof. As a result, the refrigerant that has flowed into the silencing chamber 15a can be guided smoothly to the outlet pipe 21 while at the same time avoiding a case in which the bend 21c suppresses the interference of the pressure wave.
