The present invention relates to fluoroolefin compositions. The fluoroolefin compositions of the present invention are useful as refrigerants or heat transfer fluids and in processes for producing cooling or heat. Additionally, the fluoroolefin composition...

A first check valve 620 for allowing refrigerant to flow only from a compressor 100 to an evaporator 300 (a refrigerant passage 510) is provided in a hot-gas passage 600 that conducts refrigerant discharged from the compressor 100 into the evaporator 300 w...

In an ejector cycle system, a variable throttle (450) is disposed at an upstream side of an ejector (400). When high-pressure side refrigerant pressure in the ejector cycle system is approximately equal to or higher than critical pressure of the refrigeran...

This air conditioning unit for vehicles dispenses with the coolant collector/drier and uses a hygroscopic dry coolant in the form of refrigerating machine oil with a low damp content. The unit has only one evaporator and one condenser. This allows a reduct...
