摘要： Exemplary embodiments of a cooling apparatus cool a charger for charging a storage battery upon reception of a supply of power from a power supply. Exemplary embodiments include a compressor that circulates a refrigerant, a cooling unit provided on a path along which the refrigerant flows between the heat exchanger and the expansion valve to cool the charger using the refrigerant, a refrigerant passage through which the refrigerant flows between the compressor and the heat exchanger, a refrigerant passage through which the refrigerant flows between the cooling unit and the expansion valve, and a connecting passage connecting the refrigerant passage and the refrigerant passage. When heating occurs, frost formation can be suppressed without increasing configuration complexity and power consumption.

摘要： A cooling system includes: a compressor; a first condenser; a cooling portion; a heat exchanger; a first line; a second line; a switching device; and an ejector. The first line forms a vapor compression refrigeration cycle by flowing refrigerant in order of the heat exchanger, the compressor, the first condenser and the cooling portion. The second line forms a heat pipe by circulating refrigerant between the first condenser and the cooling portion. The switching device flows refrigerant through the first line when air conditioning is performed, and flows refrigerant through the second line when air conditioning is stopped. The ejector is configured to, when refrigerant flows from the compressor to the first condenser via the ejector, draw refrigerant from the second line and join the drawn refrigerant into refrigerant from the compressor.

摘要： A scroll compressor providing a ring-shaped groove in an end plate of a movable scroll to form a backpressure chamber with a surface of a middle housing supporting the end plate and introducing a high-pressure fluid through the same so as to cancel out a thrust load generated by the compression reaction force. Inner and outer seal rings are provided to prevent leakage of the high-pressure fluid from the backpressure chamber. In this case, the seal rings are designed to be able to incline in the ring-shaped groove or O-rings are made joint use of to form a ring-shaped region of a higher contact pressure at a portion contacting the opposing surface, so a high sealing effect is obtained while suppressing mechanical loss.

A pressure at the outlet of the heat emitter 2 is controlled to a target value in accordance with the temperature of the refrigerant at the outlet of the heat emitter for obtaining an operation of the refrigerating system along the optimum control line .eta..sub.max. A pressure reducer 4 and a cooler 5 are provided on a branched passageway 28 branched from a refrigerant recirculating passageway 27 for injection.
