(54) HEATING HOLIDAY ROOM DEVICE

I

This invention relates to a device for controlling heat consumption, which can be used in the field. heat supply of residential buildings and other objects and is designed to automatically feed signals to the control room in case of a temperature deviation of the heat carrier in installations (heat point, heating boiler, heat network, etc.), operating according to the heating schedule.

A device for controlling the heat supply is known, which contains temperature sensors of the heat transfer medium and the outside air, converters, controllers "and control devices GO

The drawbacks of such a device are the availability of special autonomous MULTIPLARKSHT communication lines between the objects of control, the use of complex converters, and the use of manual operations to measure the current values of the coolant temperature performed by the dispatcher on duty.

Closest to the present invention is a device for controlling heat supply, which contains outdoor temperature and heat transfer sensors, setters, a measuring unit, an amplifier, a signal separation tree and a display unit, with temperature sensors and setters connected to the corresponding inputs of the measuring unit, the output of which is through the amplifier connected to the input of the C2 signal separation unit.

The disadvantage of this device is that it does not provide for dispatching separate signals (warning and emergency) about the violation of a given temperature parameter at the facility, which significantly limits the actions of the on-duty dispatcher to take the necessary measures. The purpose of the invention is to increase the efficiency of control and heat saving. The goal is achieved by the fact that the device controls the heat supply, which contains sensors for temperature of outdoor air and heat carrier, setters, measuring unit, amplifier, signal separation unit and display unit, with temperature sensors and setters connected to the corresponding inputs of the measuring unit, output which, through an amplifier, is connected to the input of a signal separation unit, two warning and alarm generation units are introduced, a limit setting unit, and a display unit There are not two warning indicators and two alarm indicators, the outputs of the signal separation unit are connected, respectively, to the first inputs of the warning and alarm generation units, the second inputs of which are connected to the corresponding outputs of the limit setting unit, the first outputs of the warning generation units and alarms are connected to the warning indicators and the second outputs of the warning and ava iynoy alarm connected to respective alarm indicators. FIG. 1 shows a block diagram of the proposed device; in fig. 2 - heating schedule. The device contains a sensor .1 ambient air temperature, a heat transfer temperature sensor 2, 3 angle controls, a heating schedule inclination predetermined displacement 4 parallel from the heating graph, a measuring unit 5, an amplifier 6, for example, a phase-sensitive device, a signal section 7. Low heat and Lots of heat, warning and alarm generation unit 8 Low heat, warning and alarm generating unit 9 Many tel, warning alarm indicator 10 Low heat, P alarm indicator Low heat, warning indicator 12 Many heat, Alarm 13 indicator 13 of a lot of heat and block 14 for setting limit values. The device works as follows. The measuring unit 5 is adjusted using the setters 3 of the slope of the heating schedule and 4 parallel transfer of the heating schedule to the desired mode of heat supply according to the heating schedule. 0tcl the view of the temperature of the coolant from a given heating schedule. accompanied by the appearance on the diagonal of the bridge of the measuring unit 5 an imbalance signal, which is fed to the phase-sensitive amplifier, and then to the device 7 of the signal separation section, Low Heat and Lots of Heat. Depending on the phase of the signal entering the separation device 7, the corresponding block 8 or 9 of forming the warning and alarm signals includes the corresponding indication (warning or alarm) at the distribution center 10 (11) Low heat or 12. 13) Lots of heat. With a slight deviation of the current value of the coolant temperature from a given heating schedule (for example, on), a warning signal is triggered on the dispatcher station, and if the deviation is greater (for example, by 5-7 ° C or more), the alarm (Fig. 2) turns on. The size of the precautionary and alarm zone is not enough and a lot of heat when the temperature of the heat carrier is disconnected from the heating schedule is set using block 14. According to the information received, the dispatcher on duty takes the necessary measures. The use of the proposed dispatching control device makes it possible to transfer two types of controls to the control room at the control center: CAL - warning and emergency, which allows the dispatcher to more correctly assess compliance with the heating schedule and more quickly react to emergency situations. In addition, the device improves the quality of the heat supply to the consumer and provides heat savings.
