A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. A PTAC controller is operably coupled to a compressor and an indoor fan for performing a cooling cycle. The compressor is stopped after the indoor temperature drops below a target temperature, but the indoor fan continues to circulate air through an indoor portion of the PTAC until a fan stop condition occurs. The fan stop condition occurs when the discharge temperature is at or above the dew point temperature to prevent condensation on components within the indoor portion of the PTAC.

A dehumidifier drainage system includes a primary drain pan and a secondary drain pan. The primary drain pan is disposed at least partially below an evaporator. The primary drain pan includes one or more raised ribs that are configured to at least partially block air flowing across the primary drain pan as the air flows into the evaporator. The secondary drain pan is disposed at least partially between the evaporator and the primary drain pan. The secondary drain pan includes one or more downspouts. Each downspout is configured to funnel water condensed from the evaporator into an area of the primary drain pan that is at least partially surrounded by one of the raised ribs.

A self-contained pre-manufactured air unit for installation on a roof of a building and method of operation thereof has a relief passage for connection to a building to receive relief air from the building when air pressure within the building exceeds a pressure of ambient air. The relief passage is independent of an air circulation system and is located to exhaust relief air over the condenser coil to ambient air through at least one condenser fan, thereby decreasing a temperature of a refrigerant in the condenser coil.

A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. A PTAC controller is operably coupled to a proximity indication device for detecting that a proximity trigger condition exists and is configured for adjusting an operating parameter of the PTAC to adjust an outlet temperature of a flow of discharge air in response to determining that the proximity trigger condition exists. The proximity trigger condition may exist when a proximity sensor detects an occupant close to the PTAC, when a user input button is activated, or when a voice command is received.

Provided is an air conditioner. The air conditioner includes a water tank to store water, a visual body disposed over the water tank and formed of a transparent material, a watering housing to draw water stored in the water tank and to spray the drawn water to the visual body, a water level sensor to measure a water level of the water tank in a multi-stage, a top cover assembly disposed over the visual body and having a water supply hole to supply water to the water tank, and a water level display unit disposed beside the water supply hole of the top cover assembly to display a water level measured by the water level sensor in a multi-stage.

A mount unit for mounting a decorative panel on an underside of an air-conditioning apparatus main body includes a decorative panel mount fitting having a screw engagement hole that communicates with the screw insertion hole of the decorative panel and a claw that is fitted into the claw engagement hole formed on each side of the screw insertion hole of the decorative panel and a decorative panel mount screw, and is configured to be held by the decorative panel without being dropped off when the claw is fitted into the claw engagement hole and the decorative panel mount screw is engaged with the screw engagement hole with a head being oriented downward, and the decorative panel is mounted on the air-conditioning apparatus main body when the decorative panel mount screw held on the decorative panel is screwed into the screw fastening hole of the air-conditioning apparatus main body via the screw insertion hole.

A sealed heat exchange system and air conditioner are provided herein. The sealed heat exchange system may include a compressor, a heat exchanger, a line filter, a variable electronic expansion device, a primary fluid path, and an alternate fluid path. The compressor may generally increase a pressure of a flowed refrigerant within the sealed heat exchange system. The heat exchanger may be in fluid communication with the compressor and the line filter may be in fluid communication with the heat exchanger. The primary fluid path may define a fluid inlet to receive the flowed refrigerant downstream of the heat exchanger and upstream of the expansion device. The alternate fluid path may define a fluid inlet to receive the flowed refrigerant downstream of the variable electronic expansion device and upstream of the heat exchanger.
