AI Technical Summary

Benefits of technology

The present invention provides a packaged terminal air conditioner unit with a casing and a reversing valve. The unit has an interior heat exchanger with a first stage and a second stage, an exterior heat exchanger, and a phase separator. The reversing valve is in fluid communication with the compressor and is selectively directing compressed refrigerant to either the exterior heat exchanger or the second stage of the interior heat exchanger. The unit also has an ejector and distribution conduits for directing the flow of refrigerant. The invention allows for efficient cooling and heating modes of the air conditioner unit.

Problems solved by technology

Due to space constraints within the casing, selection of sealed system components for packaged terminal air conditioner units can be limited to relatively small components.
However, high efficiency compressors are typically very expensive, and large heat exchangers may not fit within the limited space available in the casing of a packaged terminal air conditioner unit.

Abstract

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.

Description

FIELD OF THE INVENTION[0001]The present subject matter relates generally to heat pump systems, such as packaged terminal air conditioner units, and sealed systems for the same.BACKGROUND OF THE INVENTION[0002]Certain packaged terminal air conditioner units include a sealed system for chilling and / or heating air. The sealed systems include various components for treating a refrigerant in order to cool or heat air. The sealed system components are generally positioned within a casing that can be mounted within a wall or window of an associated building. Due to space constraints within the casing, selection of sealed system components for packaged terminal air conditioner units can be limited to relatively small components.[0003]Packaged terminal air conditioner units are frequently classified and sold by efficiency. Customers generally prefer efficient packaged terminal air conditioner units because small improvements in heating and cooling efficiency can provide a significant reducti...
