  • INVESTIGATION INTO A COMPLETE EARTH TO WATER HEAT PUMP SYSTEM IN A SINGLE FAMILY DWELLING FOCUSSING ON THE APPLICATION OF A VERTICAL SUBSOIL HEAT EXCHANGER

Abstract

Vertical subsoil heat exchangers for heat pumps have been studied to establish the state of the art. With the purpose of designing the subsoil heat exchanger the finite element simulation model has been used to handle the characteristic features of the system, comprising heat exchanger, residence, heat pump and climate. The system comprises an electrical heat pump and a floor heating - radiator system; it was monitored during the season 1982 - 1983 and has operated so far in a monovalent mode only. Comparison of calculated and measured data shows satisfactory agreement for the complete system. The research study shows that vertical earth heat pump systems can be applied successfully for the heating of private residences. Directives are given regarding the design and application of vertical subsoil heat exchangers. Information on heat extraction, pipe temperature, COP and single tube length for different soils is presented. Heat pump cycling and moisture migration effects are not accounted for. Furthermore a cost indication is given of installation work and complete practical installations.
