Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes a vent aperture defined in a bulkhead of the PTAC through which make-up air may flow. An indoor fan urges a flow of primary make-up air at a primary flow rate and an auxiliary fan urges a flow of auxiliary make-up air at an auxiliary flow rate. A controller determines a target make-up air flow rate, e.g., based on a user setting which is determined from building code calculations factoring in expected room occupancy, room size, and other factors. The controller then operates the auxiliary fan to urge the flow of auxiliary make-up air at the auxiliary flow rate which is substantially equivalent to the target make-up air flow rate minus the primary flow rate.

Abstract: A water heater tank has several components formed of a one-piece seamless construction. The water heater tank includes a cylindrical wall with inner and outer surfaces. A helical condenser channel may be formed in the outer surface of the cylindrical wall. The water heater includes a cold water inlet. A cold water channel may be formed in the inner surface of the cylindrical wall in fluid communication with the cold water inlet and the interior volume of the tank.

Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes an auxiliary fan configured for urging a flow of make-up air from the outdoor portion into the indoor portion through a vent aperture defined by a bulkhead. A vent door is positioned proximate the vent aperture and is operatively coupled with a reed switch assembly. A controller is configured for stopping the operation of the auxiliary fan when the reed switch assembly detects that the vent door is in the closed position.

Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes an auxiliary fan positioned adjacent a vent aperture defined in a bulkhead of the PTAC. A control system includes an occupancy identification source including data indicative of a room occupancy status, such as the number of room occupants. An occupancy reader is configured for reading the occupancy identification source to determine the room occupancy status and a controller selectively operates the auxiliary fan based at least in part on the room occupancy status determined by the occupancy reader.

Abstract: The present subject matter provides a heat pump water heater appliance with a mounting assembly for coupling a compressor to a plate within a casing of the heat pump water heater appliance. The mounting assembly includes a post that extends through a foot of the compressor and a fastener that extends through the bracket and the plate into the post in order to secure the bracket and the post together. An attachment mechanism secures the post and the foot of the compressor together.

Abstract: The present subject matter provides chiller apparatus including a storage tank for storing the liquid and a refrigerant cooling system. The refrigerant cooling system includes a compressor attached to the storage tank, a condenser positioned downstream from the compressor to condense a refrigerant received therefrom, and at least one evaporator positioned downstream of the condenser and wrapped about the outer surface of the storage tank. The evaporator includes a negative pitch coil configured to direct refrigerant flow from a position near a top of the storage tank to a position near a bottom of the storage tank.

Abstract: A water heater is provided that includes a centering ring or thermal barrier that facilitates centering or alignment of a tank of the water heater while also diminishing heat loss through the bottom of the tank. Features are provided with centering ring that keep the centering ring in place and help prevent insulation from intruding under the centering ring and the tank of the water heater.

Abstract: A water heater appliance includes a support pad positioned on an outer shell of the water heater appliance. A pair of inserts is disposed within the support pad. Each insert of the pair of inserts is positioned on a respective one of an inlet conduit and an outlet conduit of the water heater appliance. The inserts have a density greater than the support pad.

Abstract: Casings for water heater appliance and methods for assembling such casings are provided. In one embodiment, a casing includes a wrapper extending generally along a vertical direction between a top edge and a bottom edge, the wrapper including an inner surface and an outer surface and defining an interior of the casing. The casing further includes a channel defined in the outer surface of the wrapper and extending generally peripherally about the wrapper adjacent to one of the top edge or the bottom edge. The casing further includes a cover coupled to the wrapper at one of the top edge or the bottom edge, the cover including a sidewall, the sidewall generally surrounding the channel. The casing further includes a fastener extending through the sidewall and the channel, the fastener coupling the wrapper and the cover together.
