Condensing apparatus for use in a refrigeration cycle and receiver-dryer used for said condensing apparatus

摘要

The condensing apparatus in a refrigeration cycle includes a condenser having a condensing portion and a receiver-dryer. The receiver-dryer includes a tank main body, a desiccant-filled-portion arranged so that an upper space is formed at an upper part in the tank main body, a refrigerant-introducing-passage for introducing the condensed refrigerant into the tank main body from the condenser, and a refrigerant-discharging-passage for discharging the liquefied refrigerant in the tank main portion. The refrigerant-introducing-passage has an outlet which opens toward an inner bottom of the tank main body. The refrigerant-discharging-passage penetrates the desiccant-filled-portion and has an inlet formed so as to open toward the upper space at an upper end of the desiccant-filled-portion and an outlet formed at a bottom portion of the tank main body. The condensed refrigerant is introduced into the inner bottom of the tank main body through the refrigerant-introducing-passage from the condensing portion of the condenser and passes through the desiccant-filled-portion upward to be accumulated in the upper space. The accumulated liquefied refrigerant is introduced into the inlet of the refrigerant-discharging-passage and flows out of the tank main body via the outlet.
