US Patent:

52612511, Nov 16, 1993

Filed:

Feb 11, 1992

Appl. No.:

7/833955

Inventors:

Mark Galiyano - Sinking Spring PA

Assignee:

United States Power Corporation - Allentown PA

International Classification:

F25B 4900

US Classification:

621766

Abstract:

A temperature control device cools the air in a space bounded by a thermally conductive structure such as a floor structure having embedded coolant pipes. Liquid coolant is provided at a temperature lower than a temperature of the air space, for example using a heat pump to lower the temperature of a coolant in a circulating path or by circulating the coolant through a ground based heat exchanger. Proportionately controllable valves or variably coupled heat exchangers allow regulation of the temperature of the liquid coolant passed through the embedded coolant pipes. A controller such as a microprocessor has outputs coupled to the valves or variable heat exchangers for regulating temperature, and inputs coupled to sensors providing sufficient data to establish the dew point of the air in the room. The controller repetitively establishes the dew point by sensing, for example, air temperature, pressure and relative humidity. The controller adjusts the temperature of the liquid coolant for maintaining the temperature of the thermally conductive structure below the temperature in the room, but at least slightly above the dew point, thereby cooling the room or at least supplementing the output of a forced air cooling system.

Abstract:

A geothermal heat exchanger having modular tube bundles is provided in a novel heat pump system. The modular tube bundles are particularly adapted to be placed within a narrow excavation in the ground, such as a trench excavated using a backhoe bucket, which trench can be V-shaped. A heat resistant soaker hose is disposed above or about the rectangular tube bundles. The soaker hose is coupled to a water source and has a number of apertures for leaching water to the soil surrounding the tube bundles for dampening the soil around the tubes and providing better thermal heat transfer and compaction. Individual tubes of the tube bundles can be made rifled or finned for better heat transfer. A scroll compressor with relatively orbiting spiral scroll fins is provided rather than a reciprocating piston compressor. The scroll compressor, unlike a reciprocating compressor, can efficiently pump fluid in a liquid state, will start against a high differential pressure, and provides more suction for oil return from the ground coils to the compressor.
