The Study Ane Application Of Ground-source Heat Pump System In The Dong Fang Hong Jun Project

Ground-source heat pump system through the use of natural renewable energy for free, enabling the heating and cooling of buildings, is the true meaning of green environmental protection and energy saving systems. Soil source heat pump system as a type of ground source heat pump system, it takes the soil as a heat source, through the tubes buried in the soil and exchange heat with the soil, the supply of indoor heating or cooling. The paper combines the research of ground-source heat pump system at home and abroad, take the soil source heat pump technology as a topic, the main contents are as follows.1. The paper base the analysis of characteristics and application for source heat pump system in three forms:surface water, groundwater and soil source ground source heat pump system, Combined with geography geology and hydrology conditions in Wuhu.That the surface water and groundwater resources are not appropriate for hot and cold source in Wuhu, but the soil source heat pump system in the region is suitable for application.2. Combined with air conditioning engineering of Dong Fang Hong Jun in Wuhu, Through the analysis and calculation, Obtains the air conditioning project the summer air conditioning cold load, the winter air conditioning heat load, and domestic hot water load all the year round3. Paper takes air conditioning projects of soil source heat pump system for the study, technically and economically, make soil source heat pump system are analyzed and compared with conventional air conditioning systems. Research results show that soil source heat pump system energy saving effects and environmental benefits are significant.(1) Soil source heat pump system in the COP of cooling and heating has significant improvement,compared with traditional air conditioning systems, the system in winter and summer seasons,the system efficiency is increased by116%and72.1%.(2) Ground source heat pump system compared with conventional air conditioning system annual savings of electricity significantly. Thereby reducing the primary energy consumption and pollutant emissions, reduce the stress of environment, has the huge social efficiency and economic benefits.
