ABSTRACT:
A method and apparatus is disclosed for controlling the temperature in a building having a heat transfer load, a temperature control circuit containing a temperature control fluid for transferring heat energy to or from the building load, and a heat energy storage reservoir for storing heat energy. Energy is transferred between the storage reservoir and the fluid in the control circuit at optimum times to reduce the external energy required to control the temperature of the building. The amount of heat energy required to be transferred to or from the building load during a predetermined interval is predicted from load profiles. The amount of energy in the reservoir is measured to determine the amount of existing available energy to be transferred between the building load and the reservoir. A transfer unit is coupled to the control circuit to vary the heat energy in the field over the predetermined interval, so that the total energy available to be transferred is at least equal to the energy required to be transferred. Finally, the existing available energy to be transferred to or from the reservoir is dissipated by controlling the flow of fluid in the reservoir, so that the energy storage capacity is used at a rate proportional to the difference between the building heat transfer load and the rate of variation by the transfer unit. Heat energy or cooling capacity not immediately required is stored in the reservoir for later use during the predetermined interval.
