PURPOSE:To reduce the number of ducts by connecting cold and hot water sources to the room requiring both of heating and cooling via a main pipe and connecting the main pipe to a room requiring either one of heating and cooling via subsidiary pipe with a valve controlled in response to water temperature. CONSTITUTION:A room A requiring heating and cooling is equipped with an air conditioner 1A to which hot or cold water is selectively supplied from a hot or cold water source 2, 3 through a valve 5, 6, for heating the room A. On the other hand, hot or cold water is supplied to the air conditioner 1B of the room B requiring either heating or cooling from the main pipe 4 through the subsidiary pipe 7 with the control valve 9. With this construction, the valve 9 is opened or closed depending on cooling or heating and on the water temperature within the subsidiary pipe, controlling the air conditioner 1B, thereby reducing the number of ducts. |
