Fisher, S

A building heating and cooling system for using waste heat to thermally energize thermal storage media to control the temperature of a relatively large pool of water is described comprising: conduit means for circulating the water in the pool; a heat pump having a single refrigeration fluid compressor with a suction inlet and a pressure discharge outlet; a refrigerant fluid for use in the compressor; a first fluid-to-fluid heat exchange means in fluid communication with the pressure discharge of the compressor; a first refrigerant fluid reversing valve means in fluid communication with the first fluid-to-fluid heat exchange means; a second fluid-to-fluid heat exchange means in fluid communication with the first reversing valve means, the second fluid-to-fluid heat exchange means having a first input and output and a second input and output, the second heat exchange means for indirect heat exchange with the water in the pool or spa; a fluid-to-air heat exchange means for indirect heat exchange between the refrigerant fluid in the fluid-to-air heat exchange means and an airspace, the fluid-to-air heat exchange means being fluidly connected to the first output of the second heat exchange means and directly to the first refrigerant fluid reversing valve means without passing through the second reversing valve means; a second refrigerant fluid reversing valve means in fluid communication with the suction inlet of the refrigerant fluid compressor; refrigerant fluid conduit means associated with each of the heat exchange means; valve means operably defining a refrigerant fluid conduit pathway together with the first and second reversing valve means for directing fluid flow direction through the refrigerant fluid conduit pathway wherein the second fluid to fluid heat exchange means operates as a condenser in indirect heat exchange with the conduit means for circulating pool water.
