Benefits of technology

[0006]In a first exemplary embodiment, a packaged terminal air conditioner unit is provided. The packaged terminal air conditioner unit includes a casing. A compressor is positioned within the casing. The compressor is operable to increase a pressure of a refrigerant. An interior heat exchanger is positioned within the casing. The interior heat exchanger has a first stage and a second stage that are separate from each other. An exterior heat exchanger is positioned within the casing opposite the interior heat exchanger. A phase separator is positioned within the casing. The phase separator is configured for separating liquid refrigerant from vapor refrigerant. A reversing valve is positioned within the casing. The reversing valve is in fluid communication with the compressor in order to receive comp

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

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...
