摘要： PROBLEM TO BE SOLVED: To provide an expansion valve in which there is no error in the detection of a temperature of a low-pressure refrigerant, which has an appropriate time constant, and does not cause hunting without using activated carbon which is costly and takes a lot of man-hours in filling. SOLUTION: The expansion valve includes: an upper pressure working chamber 35 which is formed at an upper part of a diaphragm 32 in a power element 30, and in which the refrigerant is sealed; a lower pressure working chamber 36 formed at a lower part of the diaphragm 32, and communicating with a passage 9 of the low-pressure refrigerant; and a temperature sensitive bar 50 displaced together with the diaphragm 32 to drive a valve element 14, and having a tubular space 55 therein. The tubular space 55 communicates with the upper pressure working chamber 35 by passing through the diaphragm 32, and there is a gas-liquid interface 56 of the sealed refrigerant in the tubular space 55. By the existence of the gas-liquid interface 56, a temperature in the temperature sensitive bar 50 communicating with the upper pressure working chamber 35 is hardly raised, and the detection error is reduced. Furthermore, the time constant of apparent heat transfer becomes large. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To stably operate an ejector type refrigeration cycle even with a change in the flow rate of a driving flow that passes through a nozzle of an ejector. SOLUTION: A second compression mechanism 21a is provided for sucking and compressing a refrigerant flowing out of a utilization side heat exchanger 51 functioning as an evaporator and discharging the refrigerant to the refrigerant suction port 13b side of the ejector 13 in a cooling operation mode while sucking and compressing a refrigerant discharged from a first compression mechanism 11a and discharging the refrigerant to the utilization side heat exchanger 51 side in a heating operation mode. Consequently, even under such operating conditions that the suction capacity of the ejector 13 is degraded accompanied by a fall in the flow rate of driving flow of the ejector 13 in the cooling operation mode, the suction capacity of the ejector 13 is assisted by the second compression mechanism 21a, and a refrigeration cycle can be constituted without using the ejector 13 as a refrigerant pressure reducing means in the heating operation mode. The cycle can thereby be stably operated in any operation mode. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a refrigerant cycle with an ejector capable of improving COP and properly air-conditioning an air-conditioned space in both of a cooling operation mode and a heating operation mode.
SOLUTION: First and second four-way valves 12a, 12b switching a refrigerant flow channel, switches the flow channel to branch the refrigerant flowing out from an outdoor heat exchanger 13 to supply one of the refrigerants to a nozzle portion 18a of the ejector 18, and supply the other refrigerant to a using-side heat exchanger 14 while decompressing and expanding the refrigerant, and sucking the refrigerant from a refrigerant suction opening 19b of the ejector 18 in the cooling operation mode. As the liquid-phase refrigerant can be surely supplied to the using-side heat exchanger 14 by utilizing refrigerant sucking/discharging capacity of a compressor 11 even in a cycle constituted in such manner that the liquid-phase refrigerant is hardly supplied to the heat exchanger acting as an evaporator in the cooling operation mode with respect to the heating operation mode, the air-conditioning of the air-conditioned space can be properly performed in both operation modes.

摘要： PROBLEM TO BE SOLVED: To allow a refrigerant to easily flow to a second evaporator by increasing the pressure rise by an ejector, and easily form different temperature zones in the first and the second evaporators 4, 7, respectively.
SOLUTION: Hydrocarbon isobutane, ammonia, or carbon dioxide is used as the refrigerant. The relatively conventional ejector cycle uses, as the refrigerant, hydrocarbon isobutane, ammonia, or carbon dioxide having greater expansion loss. These refrigerants have an enthalpy difference, as an input of the ejector 3, which is greater than that of a refrigerant used in the conventional refrigerator. Since the refrigerator which is greater in the input of the ejector 3 is used, it is possible to increase the pressure rise by the ejector 3, which allows the refrigerant to easily flow to the second evaporator 4. This facilitates forming different temperature zones in the first and the second evaporators 4, 7, respectively, and the more effective operaton is practicable.
