| Abstract: | To improve the average coefficient of heating performance (COHP),a solar-assisted ground source heat pump (SAGSHP) heating system with latent heat energy storage tank (LHEST) is proposed. The transient operation characteristic of this system in Harbin was simulated numerically,and the influence of latent heat energy storage on the performance of SAGSHP was analyzed. Simulation results indicate that LHEST plays a very important role in operation of the system and it can make the system operate more flexibly,effectively and stably. The average COHP of the heating system is 3.82 in the whole heating period,the COHP is usually high in the initial and latter heating periods,and the highest value can reach 12.89. |
