PACKAGED TERMINAL AIR CONDITIONER UNIT

摘要

A packaged terminal air conditioner unit includes a casing. A compressor, a reversing valve and an ejector of the packaged terminal air conditioner unit are positioned within the casing. The ejector is configured for drawing vapor refrigerant into a flow of liquid refrigerant. An exterior heat exchanger and an interior heat exchanger are also positioned within the casing. The interior heat exchanger has a first stage and a second stage.

1. A packaged terminal air conditioner unit, comprising:
a casing; a compressor positioned within the casing, the compressor operable to increase a pressure of a refrigerant; an interior heat exchanger positioned within the casing, the interior heat exchanger having a first stage and a second stage; an exterior heat exchanger positioned within the casing opposite the interior heat exchanger; a phase separator positioned within the casing, the phase separator configured for separating liquid refrigerant from vapor refrigerant; a reversing valve positioned within the casing, the reversing valve in fluid communication with the compressor in order to receive compressed refrigerant from the compressor, the reversing valve configured for selectively directing the compressed refrigerant from the compressor to the exterior heat exchanger or the second stage of the interior heat exchanger; a supply conduit extending between the exterior heat exchanger and the phase separator; an ejector coupled to the supply conduit; a first distribution conduit extending between the first stage of the interior heat exchanger and the ejector; a second distribution conduit extending between the exterior heat exchanger and the first stage of the interior heat exchanger; a connection conduit extending between the phase separator and the second stage of the interior heat exchanger; and a bypass conduit extending from the phase separator around the second stage of the interior heat exchanger.
