ABSTRACT:
A refrigeration apparatus is constructed by connecting a sight glass via a refrigerant pipe at a downstream side of a supercooling unit of an integrated type condenser-receiver. A required capacity VR of a receiver is obtained by subtracting a required capacity V3 for making the sight glass bubble-free from a total of a refrigerant fluctuation buffer amount V1 for accounting differences in the operating conditions of the refrigeration cycle, and an extra capacity to account for leakage of refrigerant from the refrigeration cycle. Therefore, even when the capacity of receiver is reduced by the required capacity V3 for making the sight glass bubble free, gaseous refrigerant containing bubbles flowing from the receiver are all liquified at the supercooling unit and gaseous refrigerant will never reach the sight glass as long as the refrigeration cycle is filled with the sufficient quantity of refrigerant.
