摘要： In a cooling system for cooling a heating element mounted in a vehicle, a radiator is located at a position higher than a heat sink, which absorbs heat from the heating element. When the amount of heat generated from the heating element, which is detected by a sensor, is greater than a predetermined first value, a blower is operated. Further, when the detected amount of heat is greater than a predetermined second value that is higher than the predetermined first value, a pump is operated. When the detected amount of heat is equal to or less than the predetermined first value, the pump is stopped and the cooling water is circulated by a principle of heat siphon. Accordingly, power consumption of the pump is reduced. Further, power consumption of the cooling system is reduced or an increase in power consumption of the cooling system is restricted.

摘要： In an ejector cycle having an ejector, a decompression amount of refrigerant between a gas-liquid separator and an evaporator is adjusted by a differential pressure control valve, so that a pressure increasing amount in a pressure increasing portion of the ejector is controlled to be equal to or lower than a predetermined amount. Therefore, a suction pressure of refrigerant to be sucked to the compressor can be restricted from being excessively increased in accordance with the increase of the pressure increasing amount in the ejector, and it can prevent heat radiating capacity of a radiator from being decreased. Thus, a sufficient cooling capacity can be always obtained in the ejector cycle.

摘要： A cooling system for a vehicle has a refrigeration system with an ejector pump for ejecting fluid heated by a first heating element. The fluid is ejected at high speed to circulate the refrigerant and induce an entrainment effect. A radiator cools the refrigerant ejected from said ejector pump and an evaporator evaporates the refrigerant to generate refrigerating capacity. A first refrigerant circuit has a heat recovery circuit for exchanging heat between the first heating element and the refrigerant, ejecting the refrigerant and taking heat from the first heating element into the radiator via the heat recovery circuit with the use of the ejector pump, making the radiator dissipate the heat of the refrigerant, separating the refrigerant into gas-phase refrigerant and liquid-phase refrigerant by a gas-liquid separator, and making the gas-phase refrigerant return to the heat recovery circuit. A second refrigerant circuit decompresses the liquid-phase refrigerant.

摘要： In an ejector cycle having an ejector for decompressing refrigerant, a check valve is disposed in an oil return passage through which refrigerant including a lubrication oil is introduced from a refrigerant outlet side of an evaporator to a refrigerant suction side of a compressor while bypassing the ejector. When the lubrication oil amount staying in the evaporator reduces, the check valve is automatically closed, and a normal operation mode of the ejector cycle is automatically set. On the contrary, when a large amount of lubrication oil stays in the evaporator, the check valve is automatically opened, and an oil return mode is automatically set. Therefore, the lubrication oil staying in the evaporator can be controlled equal to or lower than a predetermined amount, thereby effectively returning the lubrication oil to the compressor.

摘要： An air conditioner includes a compressor for compressing refrigerant, an exterior heat exchanger for performing heat exchange between refrigerant and outside air, an interior heat exchanger for performing heat exchange between the refrigerant and air to be blown into the compartment, a decompression unit for decompressing high-pressure refrigerant, and a heater that heats air using high-temperature refrigerant discharged from the compressor as a heating source. In a dehumidifying and heating operation, refrigerant in the interior heat exchanger absorbs heat from air so that the air is cooled and dehumidified, and the heater heats air having been dehumidified and cooled by using the heating source, so that low-humidity and high-temperature air is supplied into the compartment. The heater can be disposed to indirectly heat air by heating a fluid flowing through a heater core for heating air, or to directly heat air to be blown into the compartment.

摘要： A first check valve 620 for allowing refrigerant to flow only from a compressor 100 to an evaporator 300 (a refrigerant passage 510) is provided in a hot-gas passage 600 that conducts refrigerant discharged from the compressor 100 into the evaporator 300 without passing through a radiator 200 and an ejector 400. Therefore, the refrigerant can be prevented from flowing into the hot-gas passage 600 during normal operation. In normal operation, the refrigerant in the hot gas passage 600 from the low pressure side (on the side of the evaporator 300) can be prevented from being retained in the hot-gas passage 600, so that the required amount of refrigerant can be reduced and the cost of producing the ejector circuit can be also reduced.

摘要： The present invention provides a cryogenic refrigerating system for achieving ultra low temperature by sequentially obtaining low temperature through repetition of expansion and evaporation of a mixed-refrigerant in multiple stages. The refrigerating system includes a heat exchanger and a compressor between a final evaporator and a compressor. The heat exchanger causes evaporated refrigerant vapor in a suction tube for the compressor to be heated and to be drawn into the compressor, and causes the refrigerant condensed by a condenser to be supercooled. The refrigerating system includes a plurality of expansion/suction apparatuses connected with one another between the gas/liquid separator and the final evaporator.

摘要： A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that is exposed to atmospheric pressure in the embodiment being described. The venturi, when used with a pressure switch, can operate to determine a flow rate which can be used to generate a signal which in turn is used to activate or deactivate one or more of the components, such as the heat-generating component, in the system. Also shown is another embodiment wherein a circular venturi is provided to permit a venturi passageway to be defined about an axis of the pump in order to shorten the overall length of the pump and venturi combination.

摘要： A gas-liquid separator (accumulator) is arranged at a refrigerant suction side of a compressor of a refrigerant cycle system mounted in a vehicle. The gas-liquid separator includes a gas-liquid separation portion for separating refrigerant into gas refrigerant and liquid refrigerant, and a liquid refrigerant storage portion for storing therein the separated liquid refrigerant. In the gas-liquid separator, the gas-liquid separation portion is arranged approximately vertically, and the liquid refrigerant storage portion is arranged approximately horizontally with respect to the approximately vertically arranged gas-liquid separation portion. Therefore, mounting performance of the gas-liquid separator in the vehicle can be effectively improved while gas-liquid separation can be accurately performed.
