摘要： A refrigeration device includes a compression mechanism, a radiator, a first expansion mechanism, a liquid receiver, a second expansion mechanism, an evaporator, a pressure detector, a temperature detector, and a control unit. The pressure detector is provided between the refrigerant discharge side of the compression mechanism and the refrigerant inflow side of the first expansion mechanism. The temperature detector is provided between the exit side of the radiator and the refrigerant inflow side of the first expansion mechanism. The control unit controls the first expansion mechanism using the pressure detected by the pressure detector and the temperature detected by the temperature detector so that the refrigerant flowing out from the first expansion mechanism reaches a saturated state.

摘要： In a vehicle air conditioner, a variable displacement compressor has a control valve for continuously changing a discharge capacity of the compressor, and a control unit calculates an electrical value DT to be applied to the control valve based on the following formula of DT=DT(n−1)+Kp[(En−En−1)+C/(Ti×En)]. In this formula, En=Te−Teo, Kp=Kp′/(Ph×Ph′), Ti=Ti′/(Ph×Ph″), C is a sampling cycle, n is a positive number, Kp′, Ti′, Ph′ and Ph″ are constants, Ph is a refrigerant pressure at a high pressure side, Te is a detected air temperature at an air outlet of the evaporator, and Teo is a target evaporator air temperature that is calculated based on an outside air temperature Tam. Accordingly, the compressor can be stably controlled in a wide thermal load range.

摘要： The object of the present Invention is to provide an expansion valve including a pressure sensor which enables reduction of parts cost. A pressure sensor is screwed into an opening of a body block, which communicates with a space accommodating a valve element and a compression coil spring for urging the valve element toward a valve seat. A set value for an expansion valve is adjusted by changing the amount of screwing of the pressure sensor to thereby change the load of the compression coil spring. An adjusting screw for adjusting the set value for the expansion valve can be dispensed with, which makes it possible to reduce the manufacturing costs of the expansion valve.

摘要： A bypass line is described that is capable of equalizing pressure within an HVAC system. The bypass line can also cause less noise than other solutions. A bypass line under the present disclosure can comprise a line from a high pressure side to a low pressure side of an HVAC system. Valves and orifices can be disposed within the bypass line. The valves and orifices help to slow the speed of fluid from high pressure to low pressure locations, thus reducing noise during pressure equalization.

摘要： A method of operating a refrigeration and heating system (2a, 2b) comprises: circulating a refrigerant through a refrigeration circuit (4) which comprises in the direction of flow of the circulating refrigerant: at least one compressor (6a, 6b, 6c); a refrigeration circuit side (8a) of a coupling heat exchanger (8); at least one gas cooler (10); at least one expansion device (12, 14); and at least one evaporator (16); circulating a heating fluid through a heating circuit (20) which comprises a heating circuit side (8b) of the coupling heat exchanger (8) and at least one heat consumer (22); wherein the coupling heat exchanger (8) is configured for transferring heat from the circulating refrigerant to the circulating heating fluid. The method further includes increasing the temperature of the refrigerant entering the at least one gas cooler (10) in order to meet increased heating demands by allowing at least a portion of the heating fluid to flow directly from an outlet to an inlet of the heating circuit side (8b) of the coupling heat exchanger (8) bypassing the at least one heat consumer (22) or by allowing at least a portion of the refrigerant circulating through the refrigeration circuit (4) to bypass the coupling heat exchanger (8).

摘要： A control valve of an embodiment includes a disc coaxially in contact with a diaphragm, and a shaft configured to transmit a drive force in an axial direction caused by displacement of the diaphragm to a valve element. The diaphragm has a corrugated portion between a flat portion and the outer peripheral portion, the flat portion having a contact surface with which the disc is in contact. The corrugated portion includes substantially N+0.5 corrugations (N being a natural number) each protruding relative to a reference surface, the corrugations being formed between the outer peripheral portion and the flat portion, the reference surface being one surface of the outer peripheral portion. A height of each of the N corrugations of the corrugated portion is smaller than a height of the flat portion, the heights each being a height relative to the reference surface in an unloaded condition.

摘要： When a fully-closable expansion valve is used, there is a possibility that the expansion valve is fully closed thereby to block a refrigerant circuit. In an air conditioner 1 of the present invention, an indoor heat exchanger 14 includes an auxiliary heat exchanger 20 and a main heat exchanger 21 disposed leeward from the auxiliary heat exchanger 20. In an operation in a predetermined dehumidification operation mode, a liquid refrigerant supplied to the auxiliary heat exchanger 20 all evaporates midway in the auxiliary heat exchanger 20, i.e., before reaching the outlet. Therefore, only an upstream partial area in the auxiliary heat exchanger 20 is an evaporation region, while an area downstream of the evaporation region in the auxiliary heat exchanger 20 is a superheat region. Further, an evaporation temperature sensor 30 which detects an evaporation temperature is disposed downstream of an expansion valve 13 in an outdoor unit 3.
