Simulation and Analysis of Air-soil Dual Source Heat Pump Energy Consumption in Cold Regions

Abstract

INTRODUCTIONThis paper mainly researches the practical engineering about Simulation of air-soil heat pump system in an office building of Shenyang, China. This system in the winter uses the air source as the main heat source and soil source as the auxiliary heat source for heating, in the summer only uses the soil source heat pump to refrigerate. METHODSThis paper mainly applies DEST software and TRNSYS software to study engineering air simulated analysis of soil heat pump system and compare with a single heat source. Analyzing the energy consumption of the dual heat sources pump system and its results were compared with the single soil source heat pump system to draw a conclusion. RESULTSAnalysis of energy consumption of dual-source heat pump system in summer and winter. And energy consumption analysis of single soil source heat pump system in summer and winter. CONCLUSIONSIn terms of energy consumption, the annual energy consumption of dual heat source heat pump system is 25962.23 kWh. The annual energy consumption of single soil source heat pump system is 45573.78 kWh, saving about 43.03% of energy consumption. The superiority and development prospects of the dual heat source heat pump system is obvious and promising, in the operating cost and conservation area.
