Experimental Study And Economy Analysis Of Gound Source Heat Pump

GSHP system has advantages as high efficiency , little environment pollution , stable running and low running cost , but it still hard to be accept by consumer because the initial investment is large and its adventage of low running cost is not obvious . so it is necessary to compare it with orther heat pump and establish its energy-saving character .At the beginning of the text , the development process and sort of heat pump were introduced and then gone to the background of the reseach , gave a reasonable analysis of the prospect of GSHP application . As a new concept , GSHP's boom can't be true without the political and technical support of government . now government and scientific research institution have made a lot of progress in these area . took full advantage of the existing experimental condition of our lab , at the base of summer experiment and winter experiment , we analyzed the running character of GSHP and temperature change rule and indicated that the temperature of soil down to 10 meter of wuhan city steady at 16 centigrade about . we also explained the problems appearin the experiment and gave the emphase of design and runing of GSHP .Took the exiting building of the lab as the example , considering with the heatpump running fact, the text carried out the economy comparation about GSHP,ASHP and WSHP in initial investment , running cost , and environment protecting aspects using heat economy analysis method.due to energy consumption relate to the proformance of air conditioning system , the text adopt Qinghua's software-DeST to simulate the time-to-time load of the building . based on the load , using different heatpump equipment , and caculate each initial investment and running cost , then dicide which one is the best . The result show that though the initial investment of GSHP is the highest,its economy characteris better than ASHP .In the last part of the text , the text bring forward a new GSHP energy consumption analysis programming notion based on database . The most character is that it can auto select the biggest load according to the GSHP information user provided and early time-to-time load simulation sheet , then scan the database and find out corresponding equipment for user choose . it can also rechon the real-time electricity-consumption according to the real-time load change and get a relative accurate result compare with other routine guesstimate mathod .
