PURPOSE: To effectively use the hot air of the west side for heating the east side and save energy by providing a temperature controller for controlling a second ventilator and a second electric damper so as to make the air of a high temperature chamber blown to a low temperature chamber based on temperature signals output from first and second room temperature detectors. CONSTITUTION: During an ordinary time, electric dampers 1 and 3 are opened, an electric damper 2 is closed and control signals are sent to control valves 7 and 9 by a controller 6 depending on the temperature of a room temperature detector 4 so that a heating is proportionally controlled. Then, during an indoor heating, the electric dampers 1 and 3 are closed, the electric damper 2 is opened and the ventilator 13 of the east side is operated so that the hot air of the west side is guided into the west side. Whether the indoor heating is controlled or not is decided by comparing signals from the room temperature detectors 4 and 5 with the set value of a temperature controller 6 by itself. At this time, a control valve 7 is completely closed. Thus, the excessive hot air of the west side is blown to the east side so that a heating can be carried out and energy can be saved. |
