摘要： The present invention discloses a novel packaged terminal air conditioner (PTAC) system that is compact, leakless, and power-efficient and integrates an evaporating element that heats and evaporates the meltwater collected within a drain pan disposed of in the outdoor portion. The proposed PTAC system includes an air sealing frame configurable within the sleeve of the PTAC system to completely seal off air infiltration from the sidewalls of the sleeve. The air sealing frame configurable within the sleeve further provides sufficient insulation and prevents any thermal bridge creation and also insulates the sound that usually gets transmitted from the outdoor portion to the indoor portion of the PTAC system or sound that’s experienced in the room. The proposed PTAC has a decreased protruding length of the indoor portion within the interior of the room due to the presence of the air sealing frame.

摘要： A fan assembly includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A stator assembly (28) is located downstream of the fan rotor (18), relative to an airflow (14) direction through the fan assembly. The stator assembly (28) includes a plurality of stator vanes (30) extending between a stator hub (32) and a stator shroud (34). A flow control ring (36) is positioned between the fan rotor (18) and the stator assembly (28) to block radial flow migration in an axial spacing between the fan rotor and the stator assembly resulting from a radial flow component of an airflow (14) exiting the fan rotor (18).

摘要： An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a sterilization light assembly. The housing may define an indoor portion and outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air. The outdoor heat exchanger assembly may be disposed in the outdoor portion and include an outdoor heat exchanger. The indoor heat exchanger assembly may be disposed in the indoor portion and include an indoor heat exchanger and an indoor fan. The compressor may be in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant between the outdoor heat exchanger and the indoor heat exchanger. The sterilization light assembly may be disposed within the indoor portion below the indoor fan and directed forward to transmit an ultraviolet light emission within the indoor portion.

摘要： An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.
