Abstract An air conditioning system and method of the type wherein streams of hot water and chilled water are supplied from a central station to air treating units and the water returns to the central station from each of the units through a common return line. A storage tank in connected to receive both chilled water and heated water depending upon the operating conditions, and provides a "flywheel effect," i.e., heat is removed from the tank during periods of dominant heating load conditions by passing chilled water to the tank where it is stored in anticipation of a need for increased cooling, and heat is delivered to the tank during periods of dominant cooling load conditions by passing heated water to the tank where it is stored in anticipation of a need for increased heating.
