Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor temperature control method for a floor heating system, and is suitable for controlling a heat storage type floor heating system among floor heating systems.

(Prior Art) A heat storage type floor heating system stores heat in the floor before the room is used, and heats the room using the heat stored in the floor when the room is used.

Since it takes time for this R4I type floor heating system to store heat, it is usually necessary to predict how long it will take for the floor to reach a specified temperature, and then determine the time when the room will be used. The power is turned on to the heater to start storing heat for that amount of time earlier. In this case, the power is turned ON/OFF by a timer using a preset floor temperature set value as an index.

However, the heating period is generally a long period of 4 to 6 months or more, during which the climate changes from late autumn to early winter, and from harsh winter to early spring. Therefore, in order to achieve comfortable heating, it is necessary to adjust the temperature setting value of the temperature controller once or twice per month or season depending on each climate.In this case, the floor temperature should be adjusted to the standard heating value. It is set based on calculations or based on experience in heating operations over the past several years.

However, since the climatic conditions during actual heating operation are usually different from past experience values, it is necessary to change the set temperature in a timely manner to achieve comfortable heating.However, in general, the daily temperature Overheating or underheating occurs because heating is not carried out frequently. Overheating causes heating energy to be wasted and is uneconomical, while underheating means having to endure the cold, so the temperature settings are changed every day. In order to avoid the trouble of heating and to prevent insufficient heating, the temperature is usually set at a high temperature, which increases electricity consumption and is uneconomical. Temperature characteristics and heating time are affected by the outside temperature, so it is difficult to obtain comfortable heating by measuring only the indoor temperature and controlling the temperature.Therefore, conventional methods have been to measure the outside temperature instantaneously during heating. However, it is also being considered to change the set value of the floor g degree based on the measurement results.

(Problems with conventional technology) However, in a floor heating system, it takes time for the temperature to change, so even if you change the floor temperature setting every time the outside temperature changes, the floor temperature will not follow the change and change the setting. There is a time delay in reaching the temperature, making it impossible to obtain comfortable heating.This time delay is especially noticeable in floor heating systems with large heat storage capacities.

(Objective of the Invention) An object of the present invention is to predict the climate and external temperature during heating by using data on the climate and external temperature before heating, and furthermore, to predict the climate and external temperature during heating, and to use the data based on the actual climate and external temperature during heat storage. We provide a floor temperature control method that allows optimal heating to be achieved even when the climate and outside temperature change, and that also reduces wasted energy used in floor heating and reduces running costs. It's about doing.

(Means for Solving the Problems) The floor temperature control method of the floor heating system of the present invention measures the outside air temperature at a certain time in the past at regular intervals within a specific time, and Classified by predetermined temperature range (
Figure 4), the frequency of classification into each category is counted for each category, and the relationship between this counted value and the outside temperature mode is stored in several ways in the outside temperature memory l (Figure 1). In addition, several relationships between each outside temperature mode and the optimal floor temperature for each outside temperature mode are stored in the floor temperature memory 2 (Fig. 1), and the outside air temperature during or before heating can be stored in the past. The temperature is measured under the same conditions as the outside temperature detection conditions and classified into temperature categories, and the frequency of classification into each category is counted by counters 31 to 3n for each category.
The outside temperature mode at the time of the counted value is determined from the total (a) and the past outside temperature data stored in the outside temperature memory 1, and the determined outside temperature mode and the past outside temperature data stored in the floor temperature memory 2 are determined. The optimum bed temperature in the outside temperature mode is determined from the bed temperature data, and the temperature is set to 31 based on that temperature.
This is a list of the following items.

(Operation of the invention) The operation of the bed temperature control method for unreleased IJ1 will be explained based on FIGS. 1 to 5.

The outside temperature is measured by measuring the outside temperature, and it is classified into temperature categories (outside temperature ranks) divided into predetermined temperature ranges (for example, every 5 degrees Celsius) as shown in Figure 3. It is always outputted through the encoder 6 and inputted into the counters 31 to 3n through the decoder 7, and each counter 31 to 3n counts the frequency of input to each category (classification frequency) every time it is input.

When the measurement within the measurement time is completed, all data reading is completed, and the total count up to that point is counted for each temperature category. This counted value is sent to the outside temperature mode determination circuit 8, where the outside air temperature mode corresponding to the counted value is set to I.

(Rank 2) twice indicates the climate of November or April, and the outside temperature mode is determined to be B. The determined outside temperature mode is transmitted through the encoder 9 to the floor temperature determination circuit as shown in Figure 3. Sent to 10. Therefore, the optimum bed temperature for the outside temperature mode is determined from the outside temperature mode and the floor temperature data (FIG. 2) stored in the floor temperature memory 2.

The bed temperature W[11 is adjusted according to this determined temperature, and the bed temperature is automatically controlled.

The bed temperature in FIG. 6 shows the change when the engine is operated at the bed temperature set value determined based on the results of measuring the outside air temperature. The room temperature is the change when the floor temperature is reached.

Figure 7 shows an example of the experiment in March. 6 and 7, the room temperature during the hours of use of the room is almost the same, but there is a difference in the changes in floor temperature. That is, by selecting the optimum value for the floor temperature, stable indoor conditions can be maintained during different periods of climate.

(Effect of the invention) The present invention has the following effects.

Fully automatic floor heating is now possible. This reduces overheating and underheating, making it possible to provide comfortable floor heating.

(2) Fully automatic floor heating that adapts to the dynamics of the climate and outside temperature becomes possible, so there is almost no wastage of energy used for heating, contributing to energy conservation and significantly reducing running costs.
