Windage controller for centralized air conditioner facility

Abstract

Abstract PURPOSE:To associate a simple and high accuracy air speed sensor having a small size with a control unit and to control windage with reliability by providing an air temperature sensor for detecting the temperature of supplying air and a temperature corrector in the unit, and correcting a signal from an air speed sensor according to the signal from the temperature sensor by a temperature corrector as a supply windage signal. CONSTITUTION:Mixed air of the atmospheric air and circulated air is introduced into an air conditioner 1 having an air filter 2, a cooler 3, a humidifier 4, a heater 5 and a blower 6 to be cooled or heated. Control units 11 are installed in branch ducts 9. Each unit 11 has a unit duct 12 and a housing 13. An air speed sensor 14, an air temperature sensor 15 and a damper 16 are installed in the duct 12, and a damper opening/closing motor 17 and an electronic controller 18 are provided in the housing 13. A current responsive to the air speed and temperature of supplying air detected by the sensors 14, 15 is sent to a temperature corrector 21 in the controller 18 as air speed signal and air temperature signal to correct a current value of the air speed signal having a difference generated according to the temperature, thereby obtaining an accurate air speed.
