Title: Applicability Analysis on Absorption Ground Source Heat Pump System Assisted by Air Source Heat Pump
Abstract: In the present study, regarding the low energy efficiency of traditional central heating system in cold regions, and combining with the endothermic/reject heat unbalance of soil for application of ground source heat pump, the ground source heat pump system was proposed by using high temperature steam/water from primary network as the generator heat source and using air source heat pump to ensure the thermal balance of underground heat exchange system. The operation modes of the coupled system were introduced; the control strategy of the system operation was determined and the annual operation performance was analyzed on an office building in Harbin. The results showed that, the system average coefficient of overall performance was calculated to be 2.1, and the energy saving of the proposed system was 33.1% comparing with the traditional central heating way. The soil endothermic/reject heat unbalance rate of the system was 3.8%, which can ensure thermal balance of the soil temperature filed over one year cycle. The long-run effects of the system tended to be stable.
