Abstract: According to the present invention, a capacity for storing a refrigerant can be controlled according to changes in operating conditions such as outdoor air temperature or temperature at a load so that an optimal operation can be performed all the time regardless of change in the outdoor air temperature or the temperature at a load by securing the proper degree of supercooling even if operating conditions are changed. In addition, according to the present invention, a bellows storing a refrigerant therein is controlled to be compressed or stretched so that the refrigerant storage amount of a receiver can be easily controlled. Furthermore, according to the present invention, a volume control plate compressing or stretching the bellows and a reciprocation part moving the volume control plate up and down are formed into a gear structure and a motor so that the volume control plate can be more stably moved.
