Abstract
Abstract:In regard to an actual railway station,based on its design circumstance of air-condition heating system and its testing report of ground heat transfer characteristics,the ground source heat pump system was adopted as its cold and heat source.Considering the need for heat balance of the ground source heat pump system,this thesis analyzes the two different schemes used in railway station buildings:the one is a ground source heat pump system assisted by boiler,and the other is a coupled system of solar energy with ground source heat pump.And then respectively for both schemes,this thesis calculates the required capacity of ground source heat pump unit and the required design scale of ground heat exchanger.This thesis also discusses how to achieve the cold and heat balance for the two different schemes,and analyzes each characteristics and applicability in actual projects.Finally this thesis points out:it is necessary to use suitable and customized heat balance modes for different projects on the basis of local conditions.关键词
