    摘要： A refrigeration unit applied, for example, to an air conditioning system for a car has a condenser, an expansion valve, and an evaporator interposed in a refrigerant circulation passage in the order named. The circulation passage includes a fluid-flowing area for a liquid refrigerant from the condenser to the expansion valve, and a gas-flowing area mainly for a gaseous refrigerant from the evaporator to the compressor. The refrigeration unit is provided with a detector for detecting the presence of the gaseous refrigerant in the liquid-flowing area. If the detector detects the gaseous refrigerant, a warning light indicative of a refrigerant leak is turned on.

    摘要： A resin material for a refrigeration circuit comprising a compressor for a refrigerant, a condenser, a depressurizing/expanding means, and an evaporator, the resin material being disposed in the refrigeration circuit at such a position that the resin part comes into direct contact with the refrigerant. The resin material is characterized in that when R1234yf is used as the refrigerant, the resin material has chemical resistance at least to the refrigerant itself or ingredients generated by the decomposition of the refrigerant. This resin material is prevented from undergoing a chemical reaction with the refrigerant R1234yf itself or ingredients generated by the decomposition thereof. Consequently, refrigerant leakage caused by the decomposition of the resin material is prevented. Furthermore, clogging and a decrease in refrigerating performance, which are caused by the circulation of an undesirable compound through the circuit, are prevented. Even in a refrigeration circuit employing R1234yf, the same refrigerating performance and operation stability as in conventional refrigeration circuits can be realized.

    摘要： Disclosed is a refrigeration circuit for a vehicle air-conditioning system provided with a compressor, a condenser, a pressure-reduction/expansion means and an evaporator in this order, wherein R1234yf is used as the refrigerant and a shut-off valve for shutting off the circuit based on an excessive acceleration signal of the vehicle is provided in the circuit each of upstream and downstream of the condenser. When the refrigerant used is changed to R1234yf, which is a new-type refrigerant, it is possible to instantaneously minimize refrigerant leakage from the circuit in the event applied with an excessive impact, and to reduce the possibility of a fire starting or the like.
