<p>PURPOSE: An air-conditioning device is provided to mechanically control the flow rate of cool water and warm water which circulates a heat exchanger and a chiller according to the temperature of the exit of the heat exchanger. CONSTITUTION: An air-conditioner comprises a main body, a heat exchanger, a chiller, an opening and closing valve part(100). The heat exchanger is arranged in the internal space of the main body and the air inside the internal space is heat-exchanged. The chiller is arranged outside the main body. It is connected through the heat exchanger and the connection pipe and the cold water or the warm water is circulated by the heat exchanger. The opening and closing valve part is connected to the connection pipe and varies the opening degree of the connection pipe according to the temperature of the cooling water or the warm water. The opening and closing valve part includes a case(101), a piston valve(105), and a pressure transfer part(109). The case comprises an entrance(102), an exit(103), and a connecting flow line(104).</p> |
