ABSTRACT:
An air conditioning system furnishing temperature conditioned air to a plurality of zones each of which has its own zone damper controlled by its own space thermostat. The system has an air discharge temperature sensor downstream of the temperature conditioning heat exchanger which is connected to a microprocessor controller for controlling a plurality of stages of temperature conditioning apparatus such as heating or cooling apparatus and a damper motor control for controlling the entry of outdoor air into the system. A reset thermal comfort sensor located in a representative zone or area is connected to the microprocessor controller for varying the controlled temperature of the supplied discharge air by operating the outdoor air damper motor and the multi-stage temperature conditioning apparatus to maintain the best use of outdoor air for cooling and the most efficient operation of refrigeration cooling apparatus by ensuring maximum air delivery to the heat exchangers during the operation of the mechanical cooling apparatus.
