SU385143A1 - DEVICE FOR AUTOMATIC REGULATION OF THE TEMPERATURE OF THE PREMISES - Google Patents

Description

one

Devices are known for automatically controlling the temperature of rooms serviced by an air conditioner with an executive regulator, made with temperature sensors installed in each room, setting devices, reference units and individual temperature controllers for each room.

The disadvantage of these devices is their complexity.

The object of the present invention is to simplify the device.

This is achieved by connecting a multichannel electoral unit to the temperature sensors, the output of which is connected to a blocking unit connected to the executive regulator of the air conditioner.

On (Fig. 1, a functional diagram of the device is shown; FIG. 2 is a schematic diagram.

The device consists of temperature sensors 1 installed in each room 2 and setters 3. Each sensor is through a multichannel electoral unit 4 made of an electronic bridge 5, a circulating device 6 and a three-position output device 7, and the blocking unit 8 is connected to a single temperature regulator 9 The latter is connected to the executive regulator 10 of the air conditioner 11. The output of the multichannel electoral unit has contacts 12 and 13 for each room.

Block 8 consists of two relays RB and RM.

The thermostat 9 is made, for example, in the form of a synchronous pulse chopper, which allows adjusting the operation impulse time ("Open or Close") and the pause time of the executive regulator.

The switches Bi and B are designed to disconnect the corresponding room from the control device.

The device works as follows.

When the temperature in one room 2 changes, the temperature measured by sensor 1 becomes higher than the norm determined by unit 3 of this room. The imbalance signal through the multi-channel electoral unit 4 causes the closure of the contact 12. The relay RB becomes energized, as a result of which it turns on. In this case, the normally closed contact / PB opens to prevent the opening of the actuator 10 and the normally open contact is closed.

In this case, the executive regulator, depending on the closure (opening) of the contact of the pulse interrupter, starts to cover up with pulses until the room temperature returns to normal. When the contact 12 is opened and the executive regulator 10 stops, the relay RB de-energizes, the device returns to its original position.

If the temperature is below normal, then contact 13 is closed, the PM relay turns on 1s and. closes its normally open contact PM. In this case, the executive regulator starts to open up with pulses, bringing the room temperature to the norm.

By adjusting the air temperature in the room in question, in other rooms the temperature may change. At the same time, it will not be able to deviate from the norm below permissible limits, since the minimum inlet air temperature was determined when calculating the air conditioner // in a room with minimal thermal loads. When abnormal higher

the permissible limits of the device works as described above.

The danger of a system buildup is absent, as the process of changing and regulating the air temperature of the rooms is slow.
