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.
