Patent ID: 10724769

Abstract:
A system and method for providing useable source fluid from a thermal exchange unit and/or one or more thermal exchange and storage units is disclosed. Topologies described allow operation in an air source, a ground source, a preconditioning, a parallel and a simultaneous mode. In the air source mode conditioned source fluid is obtained exclusively from an air-to-liquid heat exchanger. In the ground source mode source fluid is obtained exclusively from a ground heat exchanger. In the preconditioning mode source fluid from the air-to-liquid heat exchanger is used to condition a ground heat exchanger. In the parallel mode source fluid is obtained from both the air-to-liquid heat exchanger and a ground heat exchangers. In the simultaneous mode, source fluid from the air-to-liquid heat exchanger is used to improve the thermal condition of a ground heat exchanger while source fluid for the heat pump is obtained from another ground heat exchanger.
