Description

four

The invention relates to heating technology and can be used to automate the operation of heating systems in buildings to maintain a predetermined temperature. The application of the proposed device is most effective in terms of frontal control of heat supply.

Control devices for supplying heat to a building are known, including positional air temperature sensors and an adder. However, they are hardware cumbersome and have a staggering control circuit.

The proposed device is characterized in that, in order to simplify the design, temperature sensors are installed in the upper and lower parts of the building and section} 1y into groups of overheating and underheating of air, and the adder is made on four electro-electric relays. The overheating sensors of the upper part of the building are connected to the first pair of n. about. contacts of the first relay and with the control input of the second relay. The overheating sensors of the lower part of the building are connected with the control input of the first relay and the first pair. about. contacts of the fourth relay. The underheating sensors of the upper part of the building are connected to the first pair of n. about. contacts of the third relay and with the control input of the fourth relay. The underheating sensors of the lower part of the building are connected with the first pair. about. contacts of the second relay and with the control input of the third relay, and the second pairs of n. about. The contacts of all relays are connected to the outputs of the control device. The drawing schematically shows the proposed device.

The measuring part of the device contains sensors (in this case, three-position) located at the top and bottom of the building. The contacts of the sensors (or individual sensors) are combined into groups I, 2 and 3, 4 overheating and underheating, respectively, of the upper and lower parts of the building and are connected to the control inputs and the first pairs of i.e. contacts of electroelectromanometric first, second, third and fourth relay 5-8. The second pair, n. relay contacts 9 are connected to the output of the control device.

When the deviation of air temperature throughout the building overheating sensors send their

signals to relay 5, which is triggered and sends a comaid pulse to the output of the device. Similarly, the adder circuit works in other modes.
