摘要： A subcool condenser having a condensation heat exchange portion, a receive portion and a supercool heat exchange portion is used as an outdoor heat exchanger that functions as a radiator in a cooling operation mode so that COP in the cooling operation mode is increased. In contrast, in a heating operation mode, a refrigerant bypass device that causes the refrigerant to flow so as to bypass the supercool heat exchange portion is provided so that pressure loss generated in the refrigerant flowing through the outdoor heat exchanger is decreased. Thereby, driving force of a compressor can be decreased and COP in the heating operation mode can be improved.

摘要： An ejector-type air-conditioning and refrigerating system according to the present invention is mounted on an automotive vehicle. The system includes a first evaporator for cooling a passenger compartment and a second evaporator for cooling a refrigerator mounted on the vehicle. Refrigerant is supplied to the first evaporator through an ejector, while the refrigerant is supplied to the second evaporator through a restrictor disposed in a branch passage. Refrigerant evaporated in the second evaporator is sucked by a sucking portion provided in the ejector through a sucking passage. A noise dissipater for suppressing noises caused by pulsating vibrations generated in the ejector is disposed in the sucking passage at a position close to the sucking portion of the ejector. The noise dissipater is postured in the sucking passage so that liquid components in the refrigerant including oil contained in the refrigerant are prevented from being retained in the dissipater.

摘要： An ejector type refrigerating cycle comprises a compressor, a heat radiating device, an ejector, and a first vaporizing device, which are connected in a circuit to form a refrigerating cycle. A bypass passage is provided between an inlet port and a suction port of the ejector, so that a part of the refrigerant is bifurcated to flow through the bypass passage. A second vaporizing device is provided in the bypass passage. An internal heat exchanger is further provided between an outlet side of the heat radiating device and the inlet side of the ejector, so that the enthalpy of the high-pressure refrigerant from the heat radiating device is reduced, to thereby increase an enthalpy difference between the inlet side and outlet side of the first and second vaporizing devices. As a result, the cooling capability by the both vaporizing devices can be improved.

摘要： A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be readially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.
