<P>PROBLEM TO BE SOLVED: To prevent the drift of a heat medium flowing to each underground heat exchanger. <P>SOLUTION: An air conditioning system (1) including a refrigerant circuit (10) with a compressor (50), an indoor heat exchanger (60), an expansion valve (70) and a heat source side heat exchanger (80) connected in sequence, includes a plurality of underground heat exchangers (20). Each underground heat exchanger (20) is filled with the heat medium inside and formed to absorb heat by the heat medium from soil. The heat source side heat exchanger (80) includes a refrigerant tube (81) and a plurality of heat medium tubes (82). The plurality of heat medium tubes (82) are connected to the underground heat exchangers (20) so that heat media in the plurality of underground heat exchangers (20) circulate independently to exchange heat with the refrigerant in the refrigerant tube (81). <P>COPYRIGHT: (C)2013,JPO&INPIT |
