China) Abstract :The ai r condi tioning system using a ground source heat p ump (GSHP) combined wi th a ra dia nt floor inte grates the adva ntages of both types , giving suc h a system large potent ial for popula rizat io n. Aft er experiment ing with one ho use’s hybrid syst em , t he design proce sses and const ruction methods for suc h a system can be summarized. In the experiment , different terminal device s we re used to a dopt varying winter and summer climatic co nditions. It i s sugge sted that the const ructor s should ma ke good use of reso urce s and wast e water during the const ruction phase. The experime ntal resul t s show that thi s hybrid syst em r uns st eadily and it support s a bet te r t emperature fi eld to meet the requirement for the huma n comfort . Finally , a hybrid syst em managment st rat egy is suggest ed. Key wor ds :ground source heat p ump (GSHP) ; radia nt floor air conditioning syst em ; design a nd const ruction 　　?????????????????? ,?? ?????? ,???????????????? ? ,????????/ ?????????。??? ??????????? ,??????????? ????? ,????????????????? ???????????。 1 　?????????????????? ????????????????????? ????? ,????????? ,???????? ? ,??????、?????、?????、???? ? ,?????、???、????????。??? ????????????????????? ,? ????????、?????、????????? ?? ,?????????? ,?????????? ????????????? ,????????? ??。 : 200 01 21 : 200 AJ 02A02 0 200 AJ 01A0 0 04 : 19 el 02 12 777 E mail l u un vip . sina. com 2 　??????????? 2 . 1　?????????????? ????????????????????? ?????? ,??????????????。? ???? ,?????????????? ,???? ??????。????????。??????? ?????????? ,???????????? ? ,?? ,?????????????[ 1 ] 。 2 . 2　?????? ??????????????????
