RECEIVER-DRYER FOR IMPROVING REFRIGERATION CYCLE EFFICIENCY

摘要

A receiver-dryer of an integrated receiver-dryer-condenser for an air-conditioning system that maximizes a liquid phase of refrigerant therein for return to a sub-cooling stage of a condenser. A receiver-dryer vessel includes a base wall, a side wall extending from the base wall, and a concave end wall terminating the si de wall. A refrigerant inlet pipe extends into the interior of the vessel and terminates in an exit end that faces the concave end wall of the vessel. The refrigerant inlet pip e is adapted for directing refrigerant into contact with the concave end wall such that t he refrigerant impinges on the concave end wall for improved dispersion into a gaseous phase that accumulates in the upper portion of the vessel and a liquid phase that flows down the walls of the vessel to accumulate in the lower portion of the vesse l and for improved separation of the liquid phase and to return to the sub-cooling sta ge of the condenser for improved sub-cooling of the liquid phase of the refrigerant.
