    摘要: A Rankine cycle system has a condenser, a heat pump connected to the condenser, a heat collecting device connected to the heat pump, and an expansion turbine connected to the heat collecting device and the condenser. The heat pump includes an expansion tank or closed vessel, a refrigerant supply conduit connected to the lower part of the expansion tank and to the condenser, and a refrigerant discharge conduit connected to the upper part of the expansion tank. An open/close valve is installed in the refrigerant supply conduit. A pressure regulating valve installed in the refrigerant discharge pipe opens when a pressure reaches a specified value or higher. A temperature regulating device can heat the refrigerant in the expansion tank to produce a refrigerant vapor of saturated temperature or higher, which vapor can be introduced into the heat collecting device.

    摘要: A CO2 cooling and heating apparatus and method permit simultaneous production of high-temperature heat source and low-temperature heat source having a temperature difference therebetween. The apparatus/method uses CO2 (carbon dioxide) as a refrigerant, and has a first refrigerating cycle circuit where the refrigerant is compressed to a supercritical zone and then decompressed via an expansion device to a pressure/temperature level of the CO2 triple point or below to thereby attain evaporation. The apparatus can include multistage compressors, intermediate cooler disposed in a first refrigerant flow path between a condenser and the expansion device. A second refrigerating cycle circuit having a second refrigerant flow path, which can branch off from the first refrigerant flow path or provided in an independent closed circuit, can be provided to carry out absorption of evaporation latent heat with the first refrigerant flow path to thereby maintain the pressure/temperature level of the CO2 triple point (Ptr) or above. A third refrigerating cycle circuit having a third refrigerant flow path also can be provided to carry out heat exchange with the second refrigerant flow path.

    摘要: A method of controlling a regulating hole for regulating an amount of light, a flow rate of fluid, a pressure of fluid passing through a tubular passage is provided.A partition wall 5 formed by a viscoelastic solid containing magnetic particles is transversely disposed in the tubular passage 3 through which light or fluid passes. The partition wall 5 is provided with a regulating hole 6 for regulating an amount of the light, a flow rate of the fluid, or a pressure of the fluid so that the regulating hole 6 penetrates in an axial direction. Magnetic field gradient is generated the partition wall 5 in a radial direction in the tubular passage 3 to thereby change an opening degree of the regulating hole 6.
