摘要： PURPOSE:To reduce oil spill to recovery device caused by the foaming of accumulated oil in compressor, by delaying the action of switch valve of refrigerant recovery passage connecting the recovery device and refrigerating cycle. CONSTITUTION:Refrigerant recovery device 12 which is used to recover refrigerant from refrigerating cycle 11, is connected with high pressure charging valve 9 and low pressure charging valve 10 through pipings 13 and 14. In pipings 13 and 14 valves 15 and 16 are equipped respectively. When recovery compressor 19 works, electromagnetic valve 15 is opened and after Tmin passed, electromagnetic valve 16 opens. At the moment of delayed Tmin, because the electromagnetic valve 16 is closed, oil in compressor 1 can not spill out through piping 14. Even if foaming of oil in the low pressure side of compressor 1 happens because of decompression, the oil flows out only to evaporator 5 through piping 7 and can not flow out to the recovery device 12.

摘要： PURPOSE:To enable instant heating, by a providing an automobile cooler-heater with an indoor heat exchanger air supply quantity controller exclusive for a heat pump, so that the quantity of supplied air is regulated to be low and the pressure at the high pressure side of the cycle and the temperature of blown-off air are heightened. CONSTITUTION:When a compressor 1 is driven, a coolant flows, as shown by arrows in the drawing, in heating operation and the pressure at the high pressure side of the cycle rises. If the quantity of blown-off air from an indoor heat exchanger 8 is a low value G1, the pressure at the high pressure side rises further and the temperature of the blown-off air can be made higher. However, the pressure at the high pressure side cannot exceed a limit level P1 for the protection of the coolant and component appliances. When the pressure has reached a level (a), a high pressure switch 11 acts so that an indoor heat exchanger air supply quantity controller 14 is operated by the output of the switch to change the quantity of the air to a high value G2. As a result, the pressure drops to a level (b). When the temperature of the air falls to such a level as to give no feeling of uncomfortableness and the pressure becomes the low level P2, a low pressure switch 12 acts to operate the controller 14 so that the quantity of the blown-off air becomes the value G1 again and its temperature is heightened.

摘要： PURPOSE:To obtain a high reliable check valve to perform its maintenance work further in small size, by utilizing the joint part of a piping line in a refrigerating cycle and mounting the check valve. CONSTITUTION:When a check valve 14 is built in a joint part 21, elastic members 28a, 28b made of rubber material or the like are firstly fitted to two root parts 16g, 16h of a crest part 16g in the check valve 14, and then there are internally peripherally fitted one side of an outer cylinder 16 of the check valve 14 to a pipe 10e while the other side to a union 22. Thereafter, a flared nut 23 is tightened to the union 22 to complete the joint part 21. The check valve is fixed to a piping by holding the crest part 16g together with a flange part 10i between the flared nut 23 and the union 22, further air-tightness processing means for the above is performed by arranging the elastic members 28a, 28b in a deformed state respectively with screw tightening force.
