RECEIVER TANK FOR REFRIGERATION CYCLE, HEAT EXCHANGER WITH THE RECEIVER TANK, AND CONDENSATION DEVICE FOR REFRIGERATION CYCLE

摘要

A receiver tank has a tubular tank body (30) with a refrigerant inlet hole (3a) and a refrigerant outlet hole (3b) that are formed in its lower wall (321). The upper end of the opening of the refrigerant inlet hole (3a) is positioned lower than the upper end of the opening of the refrigerant outlet hole (3b). At the upper end of the opening of the refrigerant inlet hole (3a) is provided a resistance layer (335) at which the speed of flow of a refrigerant is reduced by permeation of the refrigerant. The refrigerant flowing in from the refrigerant inlet hole (3a) permeates upward the resistance layer (335) to form a collection (R) of liquid in a space in the tank. A liquid refrigerant in the collection (R) is discharged through the refrigerant outlet hole (3b). Because of the structure above, the refrigerant can be saved, the structure can be simplified, and costs can be reduced.
