Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. ;

The control circuit in a household HVAC installation. The wires connecting to the blue terminal block on the upper-right of the board lead to the thermostat. The fan enclosure is directly behind the board, and the filters can be seen at the top. The safety interlock switch is at the bottom left. In the lower middle is the capacitor.

HVAC vent is an important part of residential structures such as single-family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

Double Deflection Bluetooth Control HVAC Vent

Double deflection Bluetooth control HVAC vent, the front part is AV (H) tuyere, the rear part is OHD electric regulating valve, is a relatively common air supply outlet (pipe air supply and indoor central air conditioning). OHD electric regulator can be used with ASD, suitable for high space. It is suitable for underground air supply air conditioning and a rainproof louver. It can be opened freely, (ventilated at ordinary times) and closed freely (cold air is prevented from entering the room in winter).

The outer frame and blade of the double deflection Bluetooth control HVAC vent and the blade are closely connected with the gear. The motor gear and blade gear bite to drive the blade to open and close. It overcomes the shortcoming that the torque of opening and closing points should be large when the old products move in parallel. It has the characteristics of a smooth switch, low noise, large air output, and can be adjusted at will.
