摘要:
In a vehicle air-conditioning system, an evaporator (9) is disposed in an air-conditioning case (10) to form a bypass passage (16) through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door (17). When a vehicle engine (4) operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.
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.

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.
