ABSTRACT:
Constant volume multizone heating/air conditioning systems are converted to variable volume air conditioning systems. Energy conservation is achieved by converting the fan drive from one requiring constant volume air flow. Instead, the volume of air flow is governed by relative heating or cooling needs. Further, mixture of heated and cooled air to achieve the desired temperature is no longer required. Temperature sensors in a zone being heated/cooled detect actual temperature there. When the actual temperature indicates a need for cooling, the vent vanes of the system are opened and the heating vent vanes are closed. The fan speed and volume of air flow are then controlled to provide the required amounts of cooled air. Conversely, when heating is sensed to be needed, the heating and cooling air vent vanes positions are reversed and the fan speed regulated to supply the requisite amount of heated air.
