ABSTRACT:
A forced air heating and/or cooling system in a building is provided with the usual main supply conduits or duct which have various branch ducts leading to different areas of the building. Pressure sensitive instruments at spaced locations in the main supply duct are connected by electrical wiring or pneumatic tubing to a comparing instrument which senses pressure signals from the different zones determining the maximum required pressure that must be supplied to the system. Zone thermostats sense increases in room temperature and operate conventional variable volume boxes to increase the supply of air thereby lowering the air pressure. The comparing instrument sends a signal to a variable speed drive comprising a motor having a spring loaded pulley connected by a drive belt to a fan pulley and the motor is electrically driven by a separate drive means to adjust the tension on the spring loaded pulley thereby changing the speed of the fan for a more economical operation.
