PURPOSE:To eliminate unnecessary energy loss of the air conditioner and make the same convenient in use by providing a control circuit consisting of two kinds of thermostats having different characteristics, in each of radiators, and controlling the heat source by connecting the aboce described control circuit to a heat source control circuit. CONSTITUTION:The control circuit IC for controlling the heat source 1 is connected to control circuits 2AC-2NC provided in respective radiators 2A-2N by means of signal lines 4A-4N. Furthermore, the control circuit 2AC is composed of an ON-OFF switch 2AC1 of the radiater itself, a first resistor 2AC2 and a first thermostat 2AC3, in series connection, and a second thermostat 2AC4 connected in parallel to the above series connection, and the characteristic of the thermostat 2AC3 differs from that of the thermostat 2AC4. The control circuits 2BC...2NC have constructions similar to the construction of the control circuit 2AC. The outputs of these control circuits are applied to the comparators IC5 and IC6 of the control circuit IC, and the heat source 1 is controlled from the sides of radiators 2A-2N, whereby unnecessary energy loss is not produced but convenience to use is improved. |
