    摘要: When a temperature of feed air blown into a space for air conditioning cannot be increased up to the target temperature in an indoor condenser of a heat pump cycle included in a gas injection cycle, the volume of the feed air flowing into the indoor condenser is decreased. Thus, the temperature of the refrigerant condensed by the indoor condenser is increased, while the amount of a compression work in a high-pressure side compression stage of the compressor is increased, which suppresses the lack of the heating capacity of the feed air blown into the space for air conditioning.

    摘要: A decompression device includes an upstream throttle portion, a middle passage portion and a downstream throttle portion, which are arranged within a body portion. The upstream throttle portion is a variable throttle including an upstream throttle passage in which the refrigerant is decompressed and expanded, and a valve body having an open degree adjusting portion configured to adjust an open degree of the upstream throttle passage. The downstream throttle portion is a fixed throttle for decompressing and expanding refrigerant flowing from the middle passage portion. Furthermore, a refrigerant passage defined from the upstream throttle portion to the downstream throttle portion through the middle passage portion is provided in the body portion, and is bent at least at a bent portion in which the refrigerant flow is bent in the body portion.

    摘要: A pipe joint structure capable of reducing the joint height (H) and fabrication costs has a connection flange member provided with a through hole piercing the thickness of the flange member. A polygonal enlarged recess greater than the inner diameter of the through hole is formed at one end of the through hole. Meanwhile, an annular protrusion protruding radially outward is formed near an end of a pipe having an outer diameter capable of insertion into the through hole. This annular protrusion has an outer diameter greater than the incircle diameter of the polygonal enlarged recess. The annular protrusion is press-fitted and fixed to the polygonal enlarged recess.

    摘要: A vapor-compression refrigerant cycle system with a refrigeration cycle and a Rankine cycle includes a compressor, a radiator, a gas-liquid separator, a decompression device and an evaporator. In the vapor-compression refrigerant cycle system, a liquid pump is disposed for supplying the liquid refrigerant in the gas-liquid separator to a heater for heating the refrigerant, a cooling means is provided for cooling the liquid refrigerant to be sucked into the liquid pump, and an energy recovery unit for expanding the refrigerant flowing out of the heater is disposed to recover thermal energy in the refrigerant from the heater. When the Rankine cycle is set so that the energy recovery unit recovers the thermal energy, the cooling means cools the liquid refrigerant to be sucked into the liquid pump. Therefore, pumping efficiency of the liquid pump can be effectively improved.

    摘要: The waste heat recovering operation mode (a Rankine cycle) is started and operated for a predetermined period of time T1 (s) (S430 to S450). In the case where the difference (P2−P1) between the upstream pressure P1 and the downstream pressure P2 of the liquid pump is higher than the predetermined pressure P, the waste heat recovering operation mode is continued. In the case where the difference (P2−P1) is not more than the predetermined pressure P, after the air conditioning mode is started (S480 to S500), the waste heat recovering operation mode is started again (S430 to S450). Due to the foregoing, it is possible to provide a heat cycle, which is provided with a refrigerating cycle and a Rankine cycle which are changeable each other, in which an incomplete start at the time of Rankine cycle can be reduced and a deterioration of the cycle efficiency can be reduced.
