Description

The invention allows to improve the quality of temperature control (T) of air in the building. This is achieved by measuring T of the coolant at the outlet of the central heat source supplying the building, generating a signal proportional to the measured value T, normalizing the signal and introducing it to correct the regulation system T in each facade of the building. 1 il.

The invention relates to the automatic regulation of heating systems in buildings, the facades of which are subjected to various environmental influences.

The purpose of the invention is to improve the quality of regulation.

The drawing shows the functional diagram of the device for pap — garden automatic temperature control.

The device contains heaters 1 and 2 installed in rooms 3 and 4 of the north and south facades and connected by a direct pipeline 5 to the outlet of the central heat supply source 6, sensors 7 and 8, and air temperature controllers 9 and 10 in the rooms of the north and south facades II and 12 installed on the return pipelines 13 and 14 of the north and south facades

buildings connected to the entrance of the central source of heat 6.

I The device further comprises a sensor 15 of the temperature of the coolant at the output of the central heat supply source 6, normalizing the converter 16 of the signal from sensor 15, two comparison circuits 17 and 18 and two stabilizing regulators 19 and 20, while the output of the normalizing converter 16 is connected to one of the inputs of the circuits 17 and 18 comparison, the other input of which is connected respectively to the outputs of the regulators 9 and 10 of the temperature, and the outputs are connected to the inputs of the stabilizing regulators 19 and 20, the outputs of which are connected to the regulating bodies 11 and 12.

The device works as follows.

The rooms 3 and 4 of the north and south facades of the building, from sensors 7 and 8, are fed to the input of temperature regulators 9 and 10. With the release of the last $

the unbalance signal, proportional to the deviation of the averaged current value of the air temperature in rooms 3 and 4 from its target value, through the comparison circuits 17 and 18, respectively, goes to the input of the stabilizing regulator 19 or 20 and is the driver for it. Depending on the magnitude and sign of the signal imbalance regulators 19 and 20 15

affect the regulators 11 and 12, increasing or decreasing the amount of coolant passing through the heaters I and 2, and thus resulting in the averaged current value of 20 temperature in rooms 3 and 4 of the northern or southern facades to its specified value.

When the outside air temperature changes in accordance with the temperature schedule, the temperature of the return heat carrier at the outlet from the central source 6 of the heat supply also changes. This change is instantly perceived by the sensor 15, a signal from which via the normalizing converter 16 is fed to the inputs of the comparison circuits 17 and 18, in which it is compared with the master signal from the temperature regulators 9 and 10. From the outputs of the circuits 17 and 18, the regulating signal enters the inputs of the regulators 19 and 20, which form it according to the selected control law and in accordance with this law begin to affect the regulators 111 and 12 earlier than the change in the coolant temperature at the heat supply source 6 reaches heaters 1 and 2.

Thus, the device has two control loops: inertial with the regulator 9 (10), which directly executes the reference signal, and low-inertia with

„Stabilizing regulator 19 (20),

reacting to relatively high frequency impacts from the output of the central heat source.
