Abstract
An environmental control system has an evaporator section comprising an evaporator for extracting heat from (and dehumidifying) air destined for the controlled space or for exhaust--this air may be a controlled mixture of fresh and recycled air--and a chiller for extracting heat from a source such as well water and from a thermal store. The heat pump condenser section comprises a condenser for rejecting heat to air entering the space and a condenser receiver for rejecting heat to the store. The system includes a system controller (not shown) programmed to control operation in a manner tending to minimize the prime energy requirement.
Claims5
An environmental control system comprising in combination:
- a non-reverse cycle heat pump, said heat pump including means for selectively extracting heat from a plurality of different heat sources, at least one of said sources being an airstream, said means including an evaporator for extracting heat energy from an air stream through which recirculated space air, fresh air, or mixtures thereof may be circulated;
- means for selectively rejecting the extracted heat into an air stream to provide heated environmental space air;
- means for recovering at least a portion of the rejected heat and utilizing the same to increase the heat content of at least one of said heat sources;
- and control means for selecting the heat sources and uses of the extracted heat in accordance with prevailing conditions and arranged so that, when available, heat is preferentially extracted from said air-stream source, said control means including means for selecting fresh air, recirculated space air, or a
