Analyze Influence Of Villa Layout On Soil Temperature Field Of GSHP System

In this paper,from the relationship between energy and environment,this paper illustrates the importance of development and application of renewable and clean energy,and puts forward the feasibility of saving energy from the perspective of HVAC.Secondly,in the field of renewable energy,selecting the soil source heat pump system to simulate.This article first carries on the theoretical analysis to the heat transfer between soil and underground pipe,introduces the theory of heat transfer and heat transfer process,then according to the calculation formula of the code and regulations calculate buried pipe parameters and design them,finally established the soil-pipe model in Fluent,analyze the situation of the soil temperature field after buried pipe absorbed the heat from it.In this paper,by using the DeST simulation software,make the simulation of thermal load on villa buildings in Shenyang in winter heating conditions by the time,from November 1st to March 31st of the following year getting hourly heat load,meanwhile outputting meteorological conditions of typical meteorological year.Research from single villa construction application of ground source heat pump system and heat transfer of soil,considering the degree of influence factors of hole spacing and depth of drilling and drilling number of effects on soil temperature field.Using the calculation formula of the code,calculate the number of holes required under the conditions of the simulation model is 4,and the use of TRNSYS simulation software that,under the same heating condition,effects of hole spacing on the average temperature of the soil is less than the change of the drilling depth.After using the Fluent simulation software to analyze the different thermal range of holes spacing under the condition of single group of heat pipe buried.On this basis,according to the layout of the villa in the actual situation,summed up three kinds of typical tube group arrangement there are the line,around the island and double-line,analysis of action of multiple tube group together,the change of soil temperature field,and simulation results show that the layout view should be carried out by heating in winter ground source heat pump system of the villa area.
