Abstract

Ondol heating is a heating method that circulates hot heating water heated by a boiler directly through a heating pipe under the floor. Above all, the heating temperature is higher than the room temperature (= indoor air temperature) because the heat source is on the floor.

However, if the level is excessive due to problems in construction and changes in the internal and external environment, fuel is wasted as a fuel, causing inconvenience to life. This will lower the cost or burden unnecessary unnecessary board purchase costs.

The basic reason that the existing Ondol heating thermostat is not suitable for the floor temperature control is that the temperature control for the ondol heating should be adjusted based on the floor, but in reality, the room temperature (= indoor air temperature) is adjusted more than the floor temperature. Because it is done.

This method can be interpreted as a sure performance when the construction environment required for heating is perfect, but it can be interpreted as a side effect, and the overheat phenomenon of the floor here is a representative example.

In addition, the current heating temperature control is installed only in one room of the room temperature controller (with a built-in temperature sensor). If the room is not heated, the other rooms will not be able to control the temperature and waste a lot of fuel. It was a reality.

This floor temperature control device is connected to the existing temperature control device, and additionally installed a temperature sensor (6) in the heating water mixer (4) to operate the circulating pump (2) in detail, and to control the floor temperature freely. It prevents in advance, improves hot water supply capacity by adjusting room temperature and room temperature in parallel, and features an even temperature control effect in each room regardless of the installation position of the room temperature controller 9.

Description

Floor thermostat. {.}

Nowadays, the boiler automatically adjusts the room temperature with a single temperature setting.

However, unlike Western society, the heating system in Korea has developed an ondol culture, so the current temperature control method needs to be supplemented to the reality.

In other words, the existing temperature sensor is part of the room, while the heat source is located on the floor.

In other words, the indoor temperature controller (with a built-in temperature sensor) is mounted only on the wall to exclude the insulation, the size of the room, and the installation environment of the heating pipe. The boiler and circulation pump will continue to run.

In particular, if the heating pipe is thinly buried, some of the light brown burn marks can be seen, and if the room temperature controller is installed at one place, the other rooms are not connected to the sensor. Not only did not see the effect of temperature control, but also a large amount of fuel was wasted was a reality.

The purpose of the present invention is to change the current ondol heating temperature control device centered on the indoor temperature (= indoor air temperature) to a combined control of the room temperature and the floor temperature, to prevent overheating of the floor according to the heating construction environment, and to install the room temperature controller. The range of options was extended to meet the necessary needs, such as related temperature control, problem solving of fuel waste, and enhanced hot water supply.

In particular, some changes in the wiring and additional installation of the temperature sensor in the heating water mixer (= or boiler return area) can achieve all of these effects, including simple configuration and easy installation without damaging the existing heating equipment. Equipped with convenience.

FIG. 1 is an overall configuration diagram of a floor temperature control device including a controller 1, a temperature sensor 6, a circulation pump 2, and the like.

Here, (7) power input terminal can be directly connected to AC220V, but is connected to boiler (5) circulating pump output for combined control with existing temperature controller.

Therefore, in this case, only when the present temperature is lower than the set temperature of the room temperature controller 9, the apparatus operates and the room temperature can be adjusted within the room temperature setting range. (At this time, if the room temperature setting range is increased, the hot water supply function can be improved while heating (floor temperature control). Especially, when the use of hot water in spring / autumn / winter is low, a sufficient amount of hot water can always be supplied. )

[Reference] Current domestic boiler (oil, gas) temperature control structure description-Domestic company standard-

Indoor temperature controller ▶ Built-in temperature sensor. Send temperature setting and control signal to boiler.

Room temperature button: For heating purposes. Set the room temperature with the dial. (Hot water can be supplied depending on set temperature and boiler storage temperature)

Bath Button: For hot water supply. At this time, since the circulation pump does not operate, heating does not occur.

Burner ▶ The temperature range is set according to the boiler's seasonal selection switch, and the burner is controlled at the hot water and heating water temperature below 100 ℃.

Circulation Pump ▶ It operates only when the heating water in the boiler is over a certain temperature. When the current temperature exceeds the room temperature setting value, the operation is turned off.

First, the flow of ondol heating is circulating pump (2) → heating water distributor (3) → living room and room → heating water mixer (4) → boiler (5) Form. [Reference] The circulation pump (2) may have a position change to the boiler (5) return port side.

Therefore, the structure of the floor temperature control device is installed by additionally installing the temperature sensor 6 in the heating water mixer 4 (although it may be installed in the water outlet part of the boiler 5 in addition to the heating water mixer 4). The temperature of the heating water can be sensed comprehensively, and as a result, the temperature of the heating water can be freely controlled by precisely turning on / off and controlling the number of circulation of the heating water to the floor heating area without continuously operating the circulation pump 2 for a long time. It is adjustable.

FIG. 2 is an electronic circuit of a floor temperature control apparatus including a power supply circuit, a comparison circuit of an OP amplifier, a monostable multivibrator (MONOSTABLE M / V), and a counter (timer) circuit.

What is unusual here is that the circulating pump 2 is operated not only by the temperature sensor 6 but also at regular time intervals, because the temperature and actual temperature of the heating water mixer 4 with the temperature sensor 6 is installed. This is to compensate for the floor heating water temperature, which may be different depending on the environment and time.

However, the operating time of the circulation pump (2) at this time is adjusted as short as possible within the allowable range for measuring the heating water temperature of the floor. To some extent, the monostable multivibrator and the counter-related peripheral circuits may be omitted. (Representative IC: IC4011, IC555, IC4040)

The floor temperature control device can freely adjust the floor temperature, thereby preventing the floor from overheating in advance.

In addition, the hot water supply ability is superior to the existing temperature controller, and the floor temperature of each room is sensed by the heating water mixer 4 so that each room has an even temperature control effect regardless of the installation position of the room temperature controller 9. It is characteristic to be able to see.
