    摘要: In a heat storage tank (100), first and second valve bodies (119, 120) are disposed to open and close first and second valve ports (119a, 120a), respectively. A density of the first valve body is made larger than that of cooling water, and a density of the second valve body is made smaller than that of cooling water. When the dynamical pressure due to cooling water is applied to the first and second valve bodies, the first and second valve ports are opened by the first and second valve bodies. On the other hand, when the dynamical pressure is not applied to the first and second valve bodies, the first valve body closes the first valve port by the weight of the first valve body, and the second valve body closes the second valve port by the buoyancy.

    摘要: A vapor-compression refrigerant cycle system with a refrigeration cycle and a Rankine cycle includes a compressor (10), a radiator (11), a gas-liquid separator (12), a decompression device (13) and an evaporator (14). In the vapor-compression refrigerant cycle system, a liquid pump (32) is disposed for supplying the liquid refrigerant in the gas-liquid separator to a heater (30) for heating the refrigerant, a cooling means (136, 39, 15, 38) is provided for cooling the liquid refrigerant to be sucked into the liquid pump, and an energy recovery unit (33) 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.
