Multi-zone thermal energy storage variable air volume hydronic heat pump system

摘要

A multi-zone thermal energy storage variable air volume heat pump system for capacity effective averaging of continuously operable heat pumps of varied capacity and each operable at its optimum capacity and assigned to a separate zone space, wherein variable air volume by- pass ducts and zone space dampers operate in response to zone space temperature, and characterized by a chilled water storage tank and pump circulating chilled water through one closed circuit, and a hot water storage tank and pump circulating hot water through another closed circuit and through a water conditioning coil, there being a downstream charging coil and a re-cooling coil in the supply air duct upstream from the air conditioning coil and each selectively in closed circuit through the chilled water storage tank, and the re-cooling coil selectively in closed circuit through the hot water storage tank, and control means therefor.
