Abstract
A packaged terminal air conditioner unit is provided. The packaged terminal air conditioner unit includes a casing. A compressor, an interior coil, an exterior coil and a reversing valve are positioned within the casing. The reversing valve is configured for selectively reversing a flow direction of compressed refrigerant from the compressor. The packaged terminal air conditioner also includes at least one ejector for combining a stream of refrigerant from a primary loop with a stream of refrigerant from an auxiliary cooling loop, thereby improving system efficiency.
Claims20
A packaged terminal air conditioner unit, comprising:
- a casing extending between an exterior side portion and an interior side portion;
- a compressor positioned within the casing, the compressor operable to compress a refrigerant;
- an exterior coil positioned within the casing at the exterior side portion of the casing;
- a primary interior coil positioned within the casing at the interior side portion of the casing;
- a secondary interior coil positioned within the casing at the interior side portion of the casing;
- a reversing valve positioned within the casing, the reversing valve being in fluid communication with the compressor in order to receive compressed refrigerant from the compressor and selectively direct the compressed refrigerant from the compressor;
- an ejector configured for combining two or more streams of refrigerant;
- a primary loop having a first portion extending between the reversing valve and the exterior coil, a second portion extending between the exterior coil and the ejector, a third portion extending between the ejector and the primary interior coil, and a fourth portion extending between the primary interior coil and the reversing valve;
- and
- an auxiliary loop conduit having a first portion extending between the third portion of the primary loop and the secondary interior coil, a second portion extending between the secondary interior coil and the second portion of the primary loop, and a third portion extending between the secondary interior coil and the ejector.
