Damper actuator controls for air conditioning systems

Abstract

Abstract A MULTIPLE ZONE AIR CONDITIONING SYSTEM IS DISCLOSED WHICH EMPLOYS ZONE TEMPERATURE SENSING UNITS FOR PRODUCING ANALOG ELECTRIC SIGNALS RELATED TO SENSED TEMPERATURES. DAMPERS ARE ASSOCIATED WITH DUCTING LEADING TO EACH ZONE TO REGULATE THE PROPORTIONS OF HEATED AND/OR COOLED AIR SUPPLIED TO THE RESPECTIVE ZONES IN RESPONSE TO THE SENSING UNIT SIGNAL FROM THE RESPECTIVE ZONE. A DAMPER UNIT IS ALSO PROVIDED FOR REGULATING THE PROPORTIONS OF VENTILATION AND RETURN AIR CIRCULATING WITHIN THE SYSTEM AS A FUNCTION OF THE TEMPERATURE OF THE WARMEST ZONE. THE ACTUATOR FOR EACH DAMPER IS ASSOCIATED WITH A RESPECTIVE CONTROL FOR GOVERNING THE POSITION OF THE DAMPER IN RESPONSE TO THE ZONE SENSING UNIT SIGNALS.
