The Designing Software’s Development Of The Heat Storage System Of Ground Coupled Heat Pump System With Seasonal Heat Storage

In China, nearly70percent of the regions need heating in winter, and most of theseareas use coal and other other traditional energy sources as their main fuel of heating.This not only exacerbated the traditional fossil energy consumption, but also brings theenvironment pollution. In this context, This paper studies the designing of the heatstorage system of ground coupled heat pump system with seasonal heat storage, whichis a new energy-saving and environmental protection heating system. The solar seasonalheat storage system consists of two parts: first is the solar collector system, second isthe soil heat storage system. Its role is to collect the non-heating solar energy stored insoil as the heat source of heat pump when heating in winter. The solar seasonal heatstorage system implements solar energy transfer season use.Firstly, This paper studies the calculation method of the solar radiation intensity,solar seasonal storage method, soil thermal properties and the heat transfer mechanismsof U-shaped pipe heat exchanger in the regenertor and take the heat. Then create themathematical model of the U-shaped pipe heat exchanger length calculation andverification and the mathematical model of solar collector area.Then, on the basis of the mathematical models, use the VB6.0developed thedesigning software of the heat storage system of ground coupled heat pump system withseasonal heat storage. Then use this software to design a seasonal heat storage systemfor a three-storey office building in Harbin. The building heating-area is1100m2,building heat load is38.9kW. The length of the required drilling is1125m. The numberof drilling is20and the drilling depth is56m. The outdoor area of pipes needs500m2and the area of solar panels is112m2.In order to verify the compiled software reliability, use Trnsys16dynamicsimulation software to establish a computer model of ground coupled heat pump systemwith seasonal heat storage. Then use the design results of compiled software as theparameters of Trnsys16simulation software to simulate. The simulation result showsthat the heat stored in soil in the non-heating season is greater than that the heat pumpremoved from the soil in heating season. The whole system can be long-running, theheat storage system designed by the self-software is reliable.
