地源热泵系统在独栋别墅中的设计+CAD图纸

摘要:地源热泵是以地表能为热源，通过输入少量的高品位能源（如电能），实现低品位热能向高品位热能转移的热泵系统。本文首先讲述了地源热泵的发展历程，工作原理和主要的优缺点。然后介绍了地源热泵空调系统在独栋别墅中的设计，包括别墅的基本设计参数，别墅的冷热负荷计算，室内空调末端设备及地源热泵机组的选型，和室外地埋管系统的设计计算。最后和传统空调系统的比较分析，得出地源热泵系统的应用前景。着重介绍了室外地埋管换热系统的设计，包括理论的地埋管传热公式，实际工程项目设计的依据，地埋管相关知识等。通过对别墅地源热泵系统的设计和分析比较，获得了地源热泵的初投资较大，与传统的空调相比，其运行费用相对较低，从长远看，地源热泵有很好的应用和推广前景的结论。7196

Ground source heat pump system in the design and comparative analysis of application single-family villas
Abstract: The Ground-Source heat pump(GSHP) takes the surface as a heat source, through input few high grades energy (for example electrical energy), and realizes the low-grades heat energy to the high grades heat energy system. This paper is tells development history, working principle, main advantages and disadvantages of the Ground-Source heat pump at the first. The following,introduces the design air conditioning system of Ground-Source heat pump in the single-family villas, including basic parameters of design single-family villas, calculate of cold and hot loads, choose indoor air conditioning terminal equipment and Ground-Source heat pump unit, and design and calculate of outdoor buried pipe. At last,analysis and comparison with traditional air conditioning, come to conclusion about the application prospect of Ground-Source heat pump. Introduces focus on design of outdoor buried pipe, including theory of buried tube heat transfer equation, the basis of a practical engineering project design, relevant knowledge of buried pipe and so on. Through design and analysis comparison of Ground-source heat pump system, obtain a result, compare with traditional air conditioning initial investment of GSHP is large, but the operating cost is low,i n the long run, round-Source heat pump have a good prospects.
