Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating control system and a heating control method,

The present invention relates to a heating control system and a heating control method, and more particularly, to a heating control system and a heating control method which detect an actual temperature of a returned water through a return pipe, Based on the actual temperature of the return water and the target temperature of the return water, while continuously controlling the flow rate of the return water returned through the return pipe, the heating using the temperature of the return water that enables proper heating according to the set room temperature A control system and a heating control method.

In buildings such as apartments, villas, apartment houses, and single-family houses where people live, when the outside temperature is lower than the living temperature, a heating system is installed so as to maintain a suitable room temperature in order to secure the warm comfort of the living space have.

Classification of conventional heating systems can be divided into individual heating, central heating, and district heating, which supplies heat sources through wide area heat supply.

The individual heating is a system in which a boiler is independently provided for each household so that each household can freely use heating or hot water supply. The central heating is installed in a machine room in a specific industrial complex, It is a facility to supply heat source through public pipes, etc. The district heating supplies hot water or steam generated from a heat production facility such as a cogeneration plant or a waste incinerator to a boiler room provided in a building, So that heating and hot water supply can be used.

On the other hand, in the case of the central heating and the district heating, it is possible to actively respond to the decrease in the efficiency of the equipment over the years compared to the individual heating, by using a heat source device having a relatively high efficiency and using specialized technology It has the advantage of reducing the total capacity of the equipment by applying the concurrent usage rate and collecting the fire power etc. in one place, so that it is easy to respond to emergency such as fire.

The central heating and district heating system includes a hot water supply pipe extending to each household to supply hot water to each household, a heating pipe connected to the hot water distributor and heating using hot water supplied to the hot water distributor, And a return pipe for returning the hot water used in the heating pipe to the boiler room through the hot water distributor.

Since the central heating system and the district heating system always supply hot water of a certain temperature range to each household, the control of the heating temperature controls the flow rate of the hot water supplied to the heating pipe installed in the room according to the heating load of each household or each room .

For this purpose, in the past, a method of controlling the heating temperature by opening or closing the flow path connected to the heating pipe according to the room temperature or controlling the heating temperature by installing the temperature sensing device or the electronic temperature control device in the hot water distributor has been used. In the case of knowledge, it is difficult to avoid over shoot due to excessive temperature deviation, and when the room temperature and the water temperature deviation are small, hot water flows to increase the temperature of the water return pipe, resulting in energy loss.

Alternatively, a non-electric liquid expansion type return water temperature regulator or memo valve may be installed in the return pipe to cause the sealed liquid to shrink or expand according to the temperature of the return water flowing through the return pipe, or the expansion / contraction expansion of the spring of the shape memory, The water temperature regulator or the memo valve is installed in a place which is difficult to be operated by a user, which is very inconvenient to operate, it is difficult to detect the defective operation, it is difficult to accurately control the temperature of the water, There is a problem in that the valve operation may not be normally performed when it occurs.

On the other hand, Japanese Laid-Open Patent Publication No. 10-2015-0047737 discloses a control system for controlling the indoor temperature by controlling the flow of return water according to the water temperature and the room temperature.

The control system disclosed in the above patent document includes a first temperature measurement unit for measuring the temperature of the return water, a second temperature measurement unit for measuring the temperature of the room, a control valve for controlling the flow of the return water, and a controller.

The control system receives the upper limit value, the lower limit value, and the target value for the room temperature from the user, and closes the control valve when the temperature of the return water measured through the first temperature measurement unit coincides with the upper limit value, The operation of opening the control valve when the temperature reaches the lower limit value is performed so that the room temperature measured through the second temperature measurement unit reaches the target value.

According to such a control system, since the heating water flows only within the set range, unnecessary waste of the heat source can be suppressed and the heating cost can be reduced.

In order to use the heating control system, the user must directly set the upper limit value and the lower limit value of the recirculation temperature as well as the target value of the room temperature. However, the user who is only accustomed to the room temperature setting sets the upper limit value and the lower limit value Not only is it not easy, but also if the upper limit value and the lower limit value are not properly inputted, there is a problem that unnecessary energy loss is caused.

Also, the heating control system continuously changes the temperature of the return water between the upper limit value and the lower limit value in such a manner that the control valve is repeatedly opened and closed in accordance with the upper limit value and the lower limit value of the water return temperature. There is a problem that the return of the temperature is discharged as it is and the energy loss is caused.

In addition, the water temperature set at the time of the temperature change of the heating supply water also automatically changes, so that the surface temperature of the floor is kept constant and heat exchange with the room air can be achieved to ensure the comfort of the indoor heat environment. There is a problem that it is difficult to realize a pleasant thermal environment by performing control irrespective of the supply water temperature.
