A refrigerant expansion device for expanding refrigerant flowing within a refrigerant line from a condenser to an evaporator in a refrigeration system. The refrigerant expansion device includes a tubular restrictor having a cylindrical main portion and a tapered nozzle portion wherein the nozzle portion includes an outlet end having an orifice. A solder ring is disposed about the tapered nozzle portion and may be press fit onto the restrictor for secure engagement therewith. During the expansion device fabrication, the tubular restrictor is inserted into the refrigerant line to a predetermined position. The exterior of the refrigerant line is then heated at the predetermined position such that heat is transferred through the refrigerant line and melts the solder ring thereby brazing the restrictor to the refrigerant line at the predetermined position.

Method of assembling an expansion device for a refrigeration system

A room air conditioner in which a blower housing is formed of a foamed insulation material. The foamed insulation material is formed in three separate pieces with each of the pieces fitting together to form a single structural unit forming the blower housing and wall portions of two separate air conduits. The pieces are configured and apertured to fit snugly together and to provide various passages for diverse components of the air conditioner.

A room air conditioner in which separate lateral air outlets are provided for returning chilled air to the room. A blower wheel is used to draw air into the air conditioner through the evaporator and a housing for the blower wheel has two volute openings that lead to separate connecting passages to the outlet openings. An easily removable filter is provided at the front panel of the air conditioner which does not require removal of the front panel for its removal. Also a highly effective exhaust air door is provided in at least one of the connecting passages for use in exhausting air from the room.
