SU672448A1 - Subscriber's inlet of building heating system - Google Patents

Description

The invention relates to heating engineering and heat supply engineering and is intended for D.LIA of use in heating systems that feed heating systems that have a predominantly façade orientation.

Subscriber inputs are known that are equipped with temperature controllers that regulate the temperature of the air in the control rooms 1.

Such regulation is not effective enough, since the heat load of these premises may be random.

The closest technical solution to the invention is the subscriber input of the building heat supply system, containing a controller with a sensing element mounted on the supply line 2 connected to the heat source and to the heating system by supply and return pipes.

This input has complex electronic control devices with program control, which excludes the possibility of its use in mass construction.

The purpose of the invention is to increase efficiency.

This goal is achieved by the fact that the subscriber input of the heat supply system

A building containing a heat source connected to the heat source and to the supply and return pipelines with a sensitive element mounted on the supply line is equipped with a heat pipe, the evaporative part of which

mounted in the return pipeline, and the condenser part is located outside the building, with the sensing element mounted on the heat pipe.

By a certain ratio of the pipe surfaces in contact with the heating and cooling medium, it is possible to provide a temperature inside the pipe equal to half the sum of the temperatures of the return water and the outside air. The estimated value of this half-sum remains almost constant during the heating season.

The drawing shows the scheme of subscriber input.

The subscriber input of the building's heat supply system contains supply and return pipelines 1 and 2 connected to a heat source, for example, a heating network 3, and water heating system 4. A regulator 5 is installed on the supply pipe, connected to a temperature sensor 6 mounted on a heat pipe 7, the lower end of which is mounted in the return pipe, and the upper one is brought out through the outer fence 8 outside the building where it is exposed to wind 9 and solar radiation 10.

During normal operation of the thermal system in windless, non-solar weather, controller 5 maintains the design flow rate, ensuring the return water temperature required by the schedule, corresponding to a constant value of half the sum of this temperature and the outdoor air temperature.

When exposed to wind 9, the heat transfer coefficient of the surface of the heat pipe will increase, and the temperature in its vapor space will decrease. In order to maintain a constant value of this temperature, the sensor 6 commands the opening of the regulator 5, after which the heat output of the heating devices increases according to the wind effect, and the return water temperature rises, which will ensure the restoration of a constant temperature value of the heat pipe 7.

When exposed to solar radiation 10, the temperature of the heat pipe 7 will increase. To maintain a constant value

At this temperature, the sensor 6 gives the command to close the valve of the regulator 5, and the heat output of the heating devices decreases, respectively, due to heat input from solar radiation.
