Abstract

This paper, MATALAB was used to simulate series-connecting of the ground-source heat pump and the solar collector. Firstly, the simulation models of heat pump unit, ground heat-exchanger and solar collector were established. Secondly, the dynamic simulation model of combined heating system under series-connecting mode was obtained through the established sub-models and mutual coupling relations. Finally, the relation between the length of ground heat-exchanger and the area of solar collector was simulated by the dynamic simulation model of combined heating system under series-connecting mode. This simulation was undertaken under the conditions of heating in winter and the same inlet water temperature for heat pump. It was found that the function equation of L=484.6-5.329S can exhibit the numerical relation between the length of ground heat-exchanger (L) and the area of solar collector (S).
