EARTH AS STORAGE MEDIUM AND HEAT SOURCE FOR HEAT PUMPS
A heating and cooling system with a 6 kW heat pump has been investigated with a solar collector and storage with vertical pipes in the ground. A solar collector of 14.4m**2 seems to be a little underdimensioned. Eight vertical pipes of 14 m length have been adequate and a simple calculation method has been developed and tested with good results. A seasonal performance factor, SPR, of 3.6 has been achieved for a period of two heating seasons. The savings in primary energy are approximately 40% compared with traditional boilers. The good result is mainly achieved by an efficient construction of the heat pump itself.
