초록 ▼

A direct expansion geothermal heating/cooling system wherein the interior air handler is sized via 100 cubic inches of interior heat exchange tube volume per 12,000 BTUs of maximum design capacity; wherein the thermal expansion valves are sized to the tonnage capacity of the air handler's design; wherein the subterranean heat exchange tubing consists of 1/8 inch to 3/16 inch outside diameter tubing with outside diameter to tube length ratios of between 1/6,400 and 1/9,600, and where the interior diameter to length ratios are between 1/9,411 and 1/18,462; wherein the interior volume of the subterranean heat exchange tubing is within 1% of the interior volume of the interior air handler's heat exchange tubing; wherein at least 40 square feet of subterranean heat exchange tubing is proportionately exposed to a 500 square foot area of earth per 12,000 BTUs of system design capacity; wherein one or more of the subterranean heat exchange tubes are finned, with fins spaced at least 1/4 inch apart; wherein the compressor's design capacity is between 20% and 33.33% less than the interior air handler's design; where the receiver and accumulator are about 20% to 50% smaller than conventionally sized; and where the geothermal heat exchange tubing is accessed via dual, or multiple, distributors and/or is installed in a vertical or angled slot from 1 inch to 1 foot wide, which is backfilled with powdered stone, heat conductive fill, flowable fill, concrete or the like.

대표청구항 ▼

[ I claim:] [13.] A direct expansion geothermal heat exchange system, comprising:subterranean heat exchange tubing;an air handler constructed with conventional air handler finned tubing in fluid connection with said subterranean heat exchange tubing, wherein said air handler finned tubing has a combined interior volume of 100 cubic inches per 12,000 BTU's of the greater of the system's heating or cooling design capacity in tonnage;a self-adjusting thermal expansion valve in fluid connection with said subterranean heat exchange tubing, wherein said valve is sized to match the greater of the system's heating or cooling design capacity in tonnage; andan accumulator in fluid connection with said subterranean heat exchange tubing, wherein said accumulator has a maximum design capacity equal to the design capacity of said air handler.
