An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, a sterilization light assembly, and a flow sensor. The housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air therefrom. The sterilization light assembly may be disposed within the indoor portion to transmit an ultraviolet light emission thereto. The flow sensor may be disposed within the indoor portion upstream from the exhaust outlet. The flow sensor may be operably coupled to the sterilization light assembly and configured to activation of sterilization light assembly in response to detecting a predetermined airflow within the indoor portion.

A lift mechanism and air supply device with lift mechanism, the lift mechanism includes a cylinder, a threaded rod rotationally arranged in the cylinder, a power source for driving the threaded rod to rotate and a threaded holder in threaded connection with the threaded rod, the threaded holder is configured to install the air supply mechanism, a space is formed between the support bracket and the threaded holder, one end of the threaded rod extends between the support bracket and the threaded holder, and a guiding element for preventing the threaded holder from rotating is arranged between the cylinder and the threaded holder.

The window air conditioning and heating unit controls the environmental conditions within a room of a building. The window air conditioning and heating unit mounts in a window of the room. The window air conditioning and heating unit measures and monitors the temperature of and the humidity in the air in the room. The window air conditioning and heating unit comprises an environmental control structure, a control circuit, and a housing. The environmental control structure provides the heat and mass transfer capabilities required to control the temperature and humidity within the room. The control circuit controls and powers the operation of the environmental control structure. The environmental control structure and the control circuit are contained in the housing.

An air conditioning unit configured to introduce outdoor makeup air to a conditioned space includes sensors to determine the characteristics of the indoor air and the outdoor makeup air. Input from the sensors is used to determine characteristics of a mixed flow of indoor air and outdoor makeup air prior to discharge of the mixed flow to the conditioned space. The air conditioning unit modifies one or more of the indoor fan speed, outdoor fan speed, compressor speed, and electronically controlled expansion device to adjust the characteristics of the mixed flow to avoid condensation.

The invention provides an induced draft fan and an air conditioning system. The induced draft fan includes a fan main body, a first temperature sensor, and a second temperature sensor. The fan main body includes an adapter connection line extending from the same for supplying power to the fan main body. The first temperature sensor is mounted on the adapter connection line, electrically connected to the control circuit board inside the fan main body and is capable of detecting an indoor temperature at a location remote from the fan main body. The second temperature sensor is disposed inside the fan main body and faces towards an air inlet end of the fan main body.
