Meckler, M

A multi-zone thermal energy storage variable air volume heating and cooling air conditioning system for capacity effective averaging in the selection of a multiplicity of continuously operable refrigeration cooling units that may vary in capacity and each operable at its optimum capacity and assigned to a separate zone space is described including: a zone space heating and cooling units and each comprising a heating means and a refrigeration means between common supply and return air ducts. The refrigeration means directs refrigerant through a condenser and through an air conditioning coil, an air intake duct from the assigned zone space delivering return air from the zone space and through the air conditioning coil, a supply air duct delivering conditioned air into the zone space from the air conditioning coil, and blower means driving air through the ducts. A variable air volume by-pass duct from the supply air duct to the intake air duct and with air volume damper means responsive to air pressure in the supply air duct, a zone space damper means at the discharge of the supply air duct into the zone space, a chilled water storage tank with pump means circulating the chilled water through a closed circuit, a charging coil in the supply air duct downstream from the air conditioning coil and a recooling coil in the supply air duct upstream from the air conditioning coil and each selectively in closed circuit by valve means through the chilled water storage tank, control means responsive to zone space temperature to operate the heating means below a selected temperature, and control means responsive to duct air temperature to open the valve means from the chilled water storage tank are included.
