摘要： An air-conditioner includes a compressor, a radiator, an evaporator, an ejector, and a separator. The compressor compresses refrigerant and variably controls an amount of the refrigerant. The radiator cools high-pressure refrigerant. The evaporator cools air blowing into a passenger compartment of a vehicle. The ejector having a nozzle jets the refrigerant at high speed. The separator separates the refrigerant into gas refrigerant and liquid refrigerant. An opening degree of a throttle of the nozzle in the ejector becomes larger so as to increase a cooling performance of the air-conditioner when the amount of the refrigerant discharged from the compressor is smaller than a maximum amount of the refrigerant.

摘要： The present invention relates to a refrigerating system and a method of operating a refrigerating system. The refrigerating system includes a compressor, a gas cooler used as a heat-dissipation type heat exchanger, an expansion valve used as a throttling means, an evaporator used as a heat-absorption type heat exchanger and an accumulator, which are connected in series with each other to form a closed circuit. The closed circuit is adapted so that the higher pressure of the closed circuit becomes the supercritical pressure of a refrigerant circulating the closed circuit. This has a control characteristic property wherein the lower evaporating pressure increases as the higher pressure increases. The lower evaporating pressure and the higher pressure are detected, respectively, and if the detected value of the lower evaporating pressure is lower than a target value for the lower evaporating pressure determined based on the above control characteristic property in correspondence to the detected value of the higher pressure, the discharge capacity of the compressor is reduced so that the lower evaporating pressure coincides with the target value.

摘要： In a CO.sub.2 refrigerant cycle, a lubricating oil for a compressor has a compatibility relative to CO.sub.2 refrigerant, and the compatibility of the lubricating oil relative to the CO.sub.2 refrigerant at a pressure lower than a critical pressure of the CO.sub.2 refrigerant is lower than that at a pressure higher than the critical pressure of the CO.sub.2 refrigerant. Thus, in a low-pressure side such as an accumulator of the CO.sub.2 refrigerant cycle, because a liquid lubricating oil is separated with a liquid CO.sub.2 refrigerant, only the lubricating oil can be readily introduced into a suction side of the compressor, and it can prevent the liquid CO.sub.2 refrigerant from being sucked into the compressor. As a result, it can prevent a damage to the compressor while preventing deterioration of coefficient of performance of the CO.sub.2 refrigerant cycle.

摘要： In a heat exchanging apparatus for a vapor compression refrigerant cycle, an internal heat exchanger is attached to an end of a radiator. The internal heat exchanger is arranged such that high-pressure refrigerant passages are closer to the radiator than low-pressure refrigerant passages. The heat exchanging apparatus can be mounted on a vehicle such that the radiator receives cooling air more than the internal heat exchanger. Because the internal heat exchanger performs heat exchange between high-pressure refrigerant and low-pressure refrigerant, performance of the internal heat exchanger is not degraded even if it is located at a part receiving less cooling air. Thus, the heat exchanging apparatus is easily mounted on a vehicle by integrating the internal heat exchanger with the radiator, without reducing a cooling capacity of the radiator.

摘要： An ejector cycle device includes a compressor that draws and compresses refrigerant, a radiator that radiates heat of high-pressure refrigerant discharged from the compressor, an ejector, a branch passage branched from a refrigerant passage between the radiator and a nozzle portion of the ejector and coupled to a suction port of the ejector, a throttle unit that is arranged in the branch passage and decompresses refrigerant, and an evaporator that is arranged on a downstream side of refrigerant flow of the throttle unit in the branch passage and evaporates refrigerant. Accordingly, even when a suction performance of the ejector is lowered, refrigerant can flow through the evaporator.

摘要： If a refrigerant leaks from an interior heat exchanger, an outside air mode is switched ON, and a first bypass channel is opened to supply air, not having passed through the interior heat exchanger, to a passenger compartment through a defroster opening portion, while also supplying air, having passed through the internal heat exchanger, to the passenger compartment through a foot opening portion. Consequently, air having passed through the first bypass channel and thereby containing a considerable quantity of outside air free from the leaked refrigerant is supplied to the upper side of the passenger compartment, while air having passed through the interior heat exchanger and thereby containing the leaked refrigerant is supplied to the lower side of the passenger compartment, which makes it possible to prevent driver inhalation of the refrigerant.

摘要： A hot water supply system wherein a flow of a refrigerant on a high-pressure side of a supercritical heat pump cycle and a flow of hot water are oppositely directed, and wherein water heated by the refrigerant on the high-pressure side is stored in heat insulating tanks of a vacuous and double structure. Water is heated with heat absorbed from the atmosphere and by the supercritical heat pump cycle having a high heat exchange efficiency &eegr;, to reduce the power required to heat the water. Therefore, hot water can be generated even in the daytime during peak power rates. Accordingly, because it is unnecessary to store hot water for daytime use in insulated tanks, system space requirements are reduced.

摘要： A modulator in a coolant recirculation line for a refrigerating apparatus. The modulator is used for storing an excess amount of the coolant recirculated in the system.

The modulator can be arranged in the middle of the heat exchanger, and defines therein a boundary between the liquid phase and the gas phase, for a separation of the gas from the coolant, so that the portion of the heat exchanger downstream of the modulator can operate as a super cooler.
