This patent describes a multi-zone thermal energy storage variable air volume heat pump system for capacity effective averaging in and selection of a multiplicity of continuously operable heat pumps that may vary in capacity and each operable at its optimum capacity and assigned to a separate zone space, and including: heat pumps comprising a refrigerant compressor with a reversing valve directing refrigerant in alternate directions through an air conditioning coil and a water 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 hot water storage tank with pump; a charging coil in the supply air duct downstream from the air conditioning coil and air-cooling coil in the supply air duct upstream from the air conditioning and each selectively in closed circuit by valve means through the chilled water storage tank, and the re-cooling coil selectively in closed circuit by the valve means through the hot water storage tank; and control means responsive to duct air temperature to open the valve means from the chilled water storage tank and its closed circuit through the charging coil for chilled water storage when excess cooling is available downstream of the air conditioning.
