Abstract (en)
An expansion device 3 containing a differential pressure control valve has a temperature-sensing actuator like a shape-memory alloy spring 21 disposed at an outlet 14. When an air conditioner is started under a high-load condition in which the outlet temperature is high, the shape-memory alloy spring 21 senses the high temperature, to urge a spring 18 determining a valve-opening point of the differential pressure control valve, whereby the differential pressure control valve is opened in advance or placed in a state capable of opening in response to a very low differential pressure, thereby making it possible to cause refrigerant to flow at a large flow rate until the outlet temperature is lowered to a certain temperature.
