<p><P>PROBLEM TO BE SOLVED: To provide an air-conditioning system capable of improving blowout temperature controllability by suppressing excessive rising of a pressure during small capacity operation of a heating middle period. <P>SOLUTION: The air-conditioning system 100 is equipped with a main coolant circuit sequentially connecting a compressor 16, an outdoor heat exchanger 15, a first throttling device 2, and an indoor heat exchanger 1 by a cooling piping, and a bypass coolant circuit branched off from between the compressor 16 and the indoor heat exchanger 1 and connected between the first throttling device 2 and the outdoor heat exchanger 15 via a coolant bypass solenoid valve 10, an auxiliary heat exchanger 9, and a second throttling device 11. A water supply bypass pipe (a water pipe) 73 is connected to the auxiliary heat exchanger 9, and the auxiliary heat exchanger 9 carries out heat exchange between a coolant passed through the bypass coolant circuit and water passed through the water supply pipe bypass pipe 73. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
