The Forecast Of Soil Temperature In Ground Source Heat Pump System In Anhui Region

With environment problem is becoming more and more prominent in our country inrecent years, so the energy conservation and environmental protection technology is moreand more attention. Ground source heat pump system is the use of shallow ground torefrigeration and heating energy conservation and environmental protection technology,thus it is favorable to promote the ground source heat pump system in the market. With thepromotion of ground source heat pump system, the underground heat accumulationproblem is also stand out, to a large extent limited long-term stable operation of groundsource heat pump system. In Anhui area as an example, the establishment of a typical hotsummer and cold winter construction model, simulating a building to run after50years ofunderground soil temperature changes, so as to design value to improve the relevantreference, as to optimize the operation mode of ground source heat pump system.This paper selected the Anhui region an office building as an example, using theDeST-C to simulate this building of all-year hourly cold and hot load. The usingsimulation software to simulate run after50years of the ground source heat pumpunderground soil temperature changes, then according to the results of simulation analysisand optimization of the structure of construction load, so as to make the ground sourceheat pump system can long-term and stable operation. And analyzing the differentbuilding cooling and heat load imbalance rate, find out suitable for office buildings in thisarea of minimum cold and hot load imbalance rate, providing reference for design ofground source heat pump system. According to simulation results, provided optimalauxiliary measures, to balance the building cooling and heat load imbalance rateFirst simulation to predict soil temperature, and taking soil temperature stability ofthe corresponding measures, can effective to optimize the design of the building plan andoperation plan, so as to achieve the long-term stable operation of the ground source heatpump, and show the energy conservation and environmental protection characteristics ofground source heat pump system...
