Apparatus for tensioning pliable airducts while supporting internal HVAC components are disclosed. An airduct system includes an airduct having a tubular wall of a pliable material. The airduct is elongate in a longitudinal direction. The airduct system further includes a frame including a hoop disposable inside the airduct to support the tubular wall in a radial direction that is perpendicular to the longitudinal direction. The hoop is less flexible than the pliable material. The airduct system also includes a sensor to be attached to the frame to be in fluid communication with a current of air within the airduct. The sensor is to provide a feedback signal that varies in response to a changing condition of the current of air.

A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a moving unit configured to move the air conditioner main body, a control unit configured to control the air conditioning unit and the moving unit, and a human body recognition unit configured to recognize a person existing in a specific space. The control unit is configured to control the moving unit so that the air conditioner main body is moved toward the person recognized by the human body recognition unit so as to supply the cold air or the warm air from the air conditioning unit to the person recognized by the human body recognition unit.

The invention relates to the air environmental control technology field and discloses an environmental control unit including a shell, cooling device, a water pipe, a heating device, a control device, a sensor, a safety protection device, an air purification device and a humidifying device set in the shell. The invention combines the efficient circulation heating supply system with the air purification device. During the rapid heating of air, the cold-hot air convection is used to accelerate the air circulation purification and humidification treatment process. The sensor detects the real-time indoor air quality and adjusts the temperature, humidity and air quality by further control of the system according to the environmental parameters. The invention uses the air convection circulation to effectively improve the air purification and humidification efficiency with very high practical value. And it is of important positive significance for the development of water heating industry.

An air conditioner includes a housing, an outdoor heat exchanger assembly including an outdoor heat exchanger and an outdoor fan, an indoor heat exchanger assembly including an indoor heat exchanger and an indoor fan, an intake conduit defining a make-up air (MUA) air flow path, a MUA fan provided in the MUA air flow path, and a heater bank. A method of operating an air conditioner includes determining that a heating function of the air conditioner is inactive; activating the MUA fan to supply MUA to the indoor heat exchanger while the heating function is inactive; determining a supplemental heating condition after activating the MUA fan; and activating the heater bank to heat the MUA within the MUA air flow path in response to determining the supplemental heating condition.
