    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： In an ejector, a nozzle includes a nozzle tapered section having an inner passage with a radial dimension reduced toward a nozzle outlet port, and a needle having a needle tapered section disposed in the inner passage. The needle tapered section has a cross sectional area reduced toward a downstream end of the needle, and the downstream end of the needle is positioned at a downstream side with respect to the nozzle outlet port. In addition, the nozzle tapered section has a taper angle (φ1) which is equal to or greater than a taper angle (φ2) of the needle tapered section. Therefore, a boundary face on the outside of a nozzle jet flow becomes in a balanced natural shape, and is controlled in accordance with an operating condition. Thus, the ejector cycle can be operated while keeping high efficiency, regardless of the thermal load of the ejector cycle.

    摘要： An oil content measuring device measures the oil content of a refrigerant in a supercritical or a vapor phase state. A refrigeration system uses the oil content measuring device. The oil content measuring device has an electrostatic capacity measuring device for measuring an electrostatic capacity of the refrigerant containing a refrigerating machine oil, a density measuring device for measuring a density of at least one of the refrigerant and the refrigerating machine oil, a computing device for performing a computation on correlation characteristics between the electrostatic capacity and an oil content which indicates the ratio of the amount of the refrigerating machine oil to the amount of the refrigerant containing the refrigerating machine oil, using the density measured by the density measuring device. An oil content determining device determines an oil content at the measuring time from an electrostatic capacity using the correlation characteristics obtained by the computing device.

    摘要： According to the present invention, in a gas injection type heat pump apparatus, the high-pressure side pressure of refrigeration cycle is detected in a heating operation, and an upper limit value of an amount of air passing through an inside heat exchanger is determined based on the detection value. The upper limit value and a set air amount set by an air amount switching lever are compared. When the set air amount is larger than the upper limit value, the amount of the air passing through the inside heat exchanger is restricted within the upper limit value. In this way, the high-pressure side pressure increases, and an intermediate pressure in a gas-liquid separator also increases. Therefore, the gas injection amount can be increased, and a heating capacity can be effectively improved.
