TECH House I horizontal coil ground coupled heat pump: 1982-1983 heating season performance
Technical Report
·
OSTI ID:5279292
A ground-coupled heat pump (GCHP) system having a 200 m (675 ft) horizontal serpentine ground coil was installed at the Tennessee Energy Conservation in Housing (TECH) facility. Experimental results for the 1982-1983 heating season showed a heating seasonal performance factor (SPF) of 2.60. Had the system been located outside the conditioned space the SPF would have been 2.04. No auxiliary electric heat was required. Soil temperature measurements indicate that the ground near the pipe never went below 0/sup 0/C. A discussion of soil moisture measurement techniques and devices is included. Moisture sensors have been installed near the coil and will be used to determine drying trends during the 1983 cooling season.
