    摘要: The invention relates to a refrigeration device comprising at least one first and one second storage chamber (26, 27) and a refrigerant circuit in which a first throttle point (9), a first heat exchanger (10) for regulating the temperature of the first storage chamber (26), a second throttle point (13), and a second heat exchanger (14) for cooling the second storage chamber (27) are connected in series. A high pressure pipe section (18) upstream of the first throttle point (9) and a low pressure pipe section (16) downstream of the second heat exchanger (14) form a first inner heat exchanger (8). A bypass pipe (11) extends parallel to the high pressure pipe section (18) to the first heat exchanger (10), and a control valve (7, 32) is provided in order to control the distribution of the refrigerant to the high pressure pipe section (18) and the bypass pipe (11).

    摘要: To provide a refrigeration cycle apparatus with improved heating capacity and improved efficiency under a low-outdoor-air-temperature condition. In the refrigeration cycle apparatus according to the present invention, a compressor, a condenser, an ejector, and a gas-liquid separator are connected in series with a refrigerant pipe; a liquid refrigerant outlet of the gas-liquid separator, an evaporator, and a refrigerant suction port of the ejector are connected in series; an internal heat exchanger and a first flow control valve are connected in series between the condenser and a refrigerant inlet of the ejector; a gas refrigerant outlet of the gas-liquid separator is connected to a suction port of the compressor; a first bypass circuit is formed that connects a refrigerant outlet of the condenser to an intermediate pressure portion of the compressor via a second flow control valve and the internal heat exchanger; and a second bypass circuit is formed that connects a refrigerant outlet of the internal heat exchanger to the liquid refrigerant outlet of the gas-liquid separator via a third flow control valve. While the second flow control valve is opened such that the refrigerant flows through the first bypass circuit, the fourth flow control valve is switched to be opened or closed, and the third flow control valve is switched to be closed or opened.

    摘要: An air conditioning system (100) for a vehicle and a vehicle having same are provided. The air conditioning system (100) includes: a compressor (1), including a compressor inlet (12) and a compressor outlet (12); a first plate heat exchanger (2), including a pair of first inlet (21) and first outlet (22), and a pair of second inlet (23) and second outlet (24); a heat radiator (3), connected between the second inlet (23) and the second outlet (24), disposed inside the vehicle; a second plate heat exchanger (71), including a pair of third inlet (711) and third outlet (712), and a pair of fourth inlet (713) and fourth outlet (714), and disposed downstream of the first plate heat exchanger (2); an external air heat exchanger (72), disposed outside of the vehicle, connected between the fourth inlet (713) and the fourth outlet (714); a first throttle control assembly (5), disposed between the first outlet (22) and the third inlet (711); and an internal refrigeration assembly (9), disposed between the compressor inlet (11) and the third outlet (712). And provided a vehicle comprising the air conditioning system (100). The air conditioning system (100) for the vehicle solves some problems existing in the prior art and caused by the direction switching of the refrigerant, such as a cooling or heating delay of, and a poor comfort, and also, the air conditioning system (100) for the vehicle shows a low power consumption.

    摘要: A chilling machine includes a refrigerant circuit through which refrigerant circulates; a compressor, a condenser, a first expander, an evaporator and an accumulator that are provided on the refrigerant circuit; a coolant circuit including a first supply path and a second supply path to which coolant is supplied at different temperatures; and a chiller that cools the coolant. The coolant circuit includes a first supply path through which low temperature coolant is supplied to the first supply destination, and a second supply path through which high temperature coolant is supplied to the second supply destination. The refrigerant circuit includes a first reheater that increases temperature of the coolant supplied through the second supply path by heats of the refrigerant discharged from the compressor, a first selective path that supplies the refrigerant discharged from the compressor to the condenser by bypassing the first reheater, a second selective path that supplies the refrigerant discharged from the compressor to the condenser through the first reheater, and a controller that adjusts quantity of the refrigerant passing through the first selective path and quantity of the refrigerant passing through the second selective path.
