Title : Assessment of operaton of heat exchangers placed in various configurations feeding a heat pump
Key words : heat pump, exchanger, lower heat source, ground
Summary :

Abstract. The paper presents the energy analysis of horizontal ground exchangers of a heat pump. Three types of exchangers made of polyethylene pipes, placed in the ground single U, double U and spirally shaped were analysed. Exchangers were placed in the depth from 1.5 to 2.3 m. Thermal capacity of exchangers at varied energy demand was determined. For the existing research conditions, it was proved that the highest amount of energy is obtained in the horizontal exchanger placed in the double U configuration, the average unit thermal power capacity of which was 21.5 W from 1 current meter of a pipe. The unit power obtained from the remaining two exchangers was at the average by 40% lower and was within the range 8 to 17 W from 1 current meter of a pipe.
