摘要： In a hot gas heating mode of an ejector cycle system, hot gas refrigerant discharged from a compressor is introduced to an interior heat exchanger while bypassing an exterior heat exchanger. The refrigerant discharged from the interior heat exchanger can flow into an ejector from at least an inlet of a nozzle of the ejector, and flows into the gas-liquid separator, in the heating mode. Alternatively, refrigerant discharged from the compressor can be supplied to the interior heat exchanger through a clearance between an outer wall of the nozzle and an inner wall of a nozzle housing portion, while bypassing the exterior heat exchanger in the heating mode. Here, the nozzle is disposed in the nozzle housing portion, and a part of pressurizing portion is defined by the nozzle housing portion. Thus, the heating mode can be readily performed in the ejector cycle system.

摘要： In a vapor-compression refrigerant cycle system, a switching device is provided to switch one of a first mode where high-pressure refrigerant discharged from a compressor is directly introduced to an exterior heat exchanger and a second mode where the high-pressure refrigerant is directly introduced to an interior heat exchanger. When the second mode is set, the pressure of the high-pressure refrigerant is set higher than a predetermined pressure by a constant-pressure control valve. Accordingly, it can prevent heating capacity of the interior heat exchanger from being greatly changed even when thermal load of the vapor-compression refrigerant cycle system is changed, and heating capacity of the interior heat exchanger can be improved in the second mode.

摘要： A vapor-compression refrigerant cycle system includes a first evaporator in which refrigerant is evaporated, a second evaporator in which refrigerant is evaporated at a pressure lower than that in the first evaporator, and a switching device for switching between a first circulation where the refrigerant is circulated to the first evaporator and a second circulation where the refrigerant is circulated to the second evaporator. When the switching device switches to the second circulation from the first circulation, a refrigerant circulation into the second evaporator is stopped until the refrigerant pressure in the second evaporator becomes equal to or lower than a predetermined pressure. Therefore, the pressure in the second evaporator can be rapidly reduced. Further, when carbon dioxide is used as the refrigerant, the pressure in the second evaporator can be further rapidly reduced.

摘要： In an ejector cycle having an ejector, a throttle is provided inside a passenger compartment adjacent to an evaporator so that a length of a refrigerant passage between the throttle and the evaporator is shortened. Therefore, it can restrict a part of liquid refrigerant after being decompressed in the throttle from being evaporated in the refrigerant passage, before being introduced into the evaporator. In addition, a refrigerant inlet is provided at a lower header tank of an evaporator. Therefore, a gas-liquid refrigerant distribution difference due to the density difference between gas refrigerant and liquid refrigerant can be effectively restricted. Thus, refrigerant distributed into the plural tubes from the lower header tank can be made uniform, even if the refrigerant flow speed is low in the ejector cycle.
摘要翻译：在具有喷射器的喷射器循环中，在与蒸发器相邻的乘客室内设置有节气门，使得在节气门和蒸发器之间的制冷剂通道的长度被缩短。因此，在将节气门减压后的液体制冷剂的一部分在制冷剂通路中蒸发之前，可以将其引入蒸发器中。此外，制冷剂入口设置在蒸发器的下集水箱处。因此，可以有效地限制由于气体制冷剂和液体制冷剂之间的密度差引起的气液制冷剂分配差异。因此，即使在喷射器循环中制冷剂流速低，也可以使从下集水箱分配到多个管中的制冷剂均匀。

摘要： A supercritical cycle comprises an evaporator, a compressor, a gas cooler and a main valve portion of an expansion valve arranged in that order. An internal heat exchanger is arranged for exchanging heat between the high-pressure side refrigerant flowing toward the main valve portion of the expansion valve from the gas cooler and the low-pressure side refrigerant flowing toward the compressor from the evaporator. The expansion valve is formed integrally with a temperature sensing portion for controlling the main valve portion, and includes a bypass for supplying the refrigerant to the temperature sensing portion from the upstream side of the internal heat exchanger in which the high-pressure side refrigerant flows and an orifice for supplying the refrigerant from the temperature sensing portion to the refrigerant circuit downstream of the main valve portion.

摘要： In a vapor compression refrigerant cycle using refrigerant having a critical temperature equal to or less than sixty degrees Celsius, when refrigerant temperature detected by a sensor as a parameter of a low-pressure side refrigerant pressure is higher than a saturation temperature corresponding to a predetermined pressure that is equal to or less than a critical pressure, a volume of air passing through an evaporator is controlled smaller than a predetermined volume by controlling operation of a blower unit. Because heat exchange rate (heat absorbing rate) in the evaporator is controlled, the pressure of the low-pressure side refrigerant is maintained below the critical pressure. Alternatively, the heat exchange rate is controlled by reducing a flow rate of the refrigerant in the evaporator.

摘要： A pressure control valve includes a valve portion disposed in a passage from a refrigerant radiator to a suction port of a refrigerant compressor in a vapor-compression refrigerant cycle system. The valve portion controls a refrigerant pressure at an outlet of the refrigerant radiator in accordance with a refrigerant temperature at the outlet of the refrigerant radiator, and the valve portion has a control pressure characteristic in which a pressure change relative to a temperature is smaller than that of the refrigerant. Furthermore, the valve portion may have a fluid passage through which refrigerant flows even when a valve port of the valve portion is closed by a valve body. Accordingly, when the refrigerant radiator is used for heating a fluid, heating capacity for heating the fluid can be rapidly increased at a heating start time.
