Abstract

PURPOSE:To attain a fully automatic floor heating system in response to the external movement like the open air temperature, etc., by using the data on the weather conditions and open air temperature measured before heating after comparing them with the open air temperatures measured before heating. CONSTITUTION:The open air temperatures are periodically detected by a open air temperature sensor 4 and measured by a temperature measuring circuit 5. These measured temperatures are stored in the temperature memories 31-3n via an A/D converter 7. The data stored in the memories 31-3n are integrated by an arithmetic circuit 9 with each addition of new data. This integrated value is sent to an open air temperature mode deciding part 10 and the part 10 decides the specific one of those open air temperature modes stored in an open air temperature memory 1 that corresponds to said integrated value. Then the decided temperature mode is sent to an application time point deciding circuit 11 and compared with the temperature increase characteristics stored in a temperature increase memory 2. The application of power supply is controlled so that the temperature reaches a desired level at a target time point.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for determining power-on time of a floor heating system, and is particularly suitable for determining power-on time of a heat storage type floor heating system.

The present invention determines when to turn on the power in order to raise the room temperature to a predetermined temperature by the time the room starts to be used, based on the climate and outside temperature, and automatically turns on the power when the time to turn on comes. It was designed so that

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

Since this type of heat storage floor heating system takes time to store heat, it is usually necessary to predict how long it will take for the floor to reach a specified temperature, and then wait for that amount of time before starting to use the room. The power is turned on to the heater to start storing heat a few minutes in advance. In this case, the power is turned ON and OFF by a timer using a preset floor temperature set value as an index.

(Problems with the Prior Art) 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 severe winter to early spring. Even if the climate is the same, there are cold days and warm days. Moreover, the temperature rise characteristics of floor heating are affected by the climate and outside temperature, so it is difficult to obtain comfortable heating by measuring only the indoor temperature and controlling the time to turn on the power switch based on that.

However, conventional power-on time control methods only uniformly advance the power-on start time by a certain amount of time, making it difficult to raise the temperature appropriately in response to changes in outside temperature due to climate changes. The temperature may rise to a predetermined temperature earlier than the time when the room starts to be used, or conversely, the temperature may not rise to the predetermined temperature even after the time when the room starts to be used. In the former case, the start of energization is too early (b < b), which is uneconomical because extra heating energy (electricity) is used, and in the latter case, the heating temperature is too slow, causing the problem of having to endure the cold until the room warms up. be.

(Objective of the Invention) The object of the present invention is to automatically set the heating start time according to changes in the climate and outside temperature, so that the indoor heating condition is comfortable at the start of use, and to use the The goal is to reduce running costs by reducing wasted energy.

(Means for Solving the Problems) The power-on time determination method of the floor heating system of the present invention measures the past outside air temperature at a constant cycle within a specific time, and integrates the measured temperature value for each meter. Then, the relationship between the integrated value and the outside temperature mode (Fig. 2) is stored in the outside temperature memory l (Fig. 1).
In addition, the temperature increase characteristics of the floor temperature in each outside temperature mode are stored in the temperature increase memory 2 (Fig. 1), and the outside temperature of the heating song is set under the same conditions as the past outside temperature measurement conditions. The measured temperature is stored in the temperature memory 31 as a temperature value.
~3n, the stored temperature value is 'm'A, the outside temperature mode is determined from this product and the past outside temperature data stored in the outside temperature memory l, and the outside temperature mode that has been determined is The temperature increase characteristics in the outside temperature mode are determined from the temperature mode and the temperature increase data stored in the temperature increase memory 2, and the target time is determined from the temperature increase characteristics and the predetermined reached floor temperature. The power-on time is determined so that the temperature reaches .

(Operation of the invention) The operation of the power-on time determination method of the invention will be explained based on FIGS. 1 to 4.

The outside temperature sensor 4 shown in FIG. 1 detects the outside air temperature at a certain period (once every 6 minutes) within a specific time (for example, one day)
The outside air temperature is measured by the temperature measuring circuit 5.

This measurement is performed every time a specific periodic signal is transmitted from the timer circuit 6.The measured outside temperature is converted from analog to digital by the A/D conversion circuit 7 and stored in the temperature memory (RAM).
) 3X to 3n. This memory 31-3Q is 2
It is possible to store 40 pieces of data (10 minutes of data once every 6 minutes), and when 240 pieces of data are stored and new data is input from the outside temperature detection unit 8, it will shift sequentially. The oldest data will be discarded.

The 240 data (temperature values) stored in the temperature memories 31 to 3n are processed by the arithmetic circuit 9 every time new data is added.
This integrated value is sent to the outside temperature mode determination section 10, and the calculated a value is compared with the outside temperature data stored in the outside temperature memory 1. It is determined which outside temperature mode the device corresponds to, and the determined outside temperature mode is output. In this case, which outside temperature mode corresponds to is determined by comparing the integrated value with the lower limit of the integrated value of the outside temperature memory l (Figure 2).For example, if the integrated value is 1800, the B It is determined that the mode is outside temperature mode.

The output outside temperature mode B is sent to the input time determination circuit 11, where it is compared with the temperature rise characteristics stored in the temperature rise memory 2, and the temperature rise characteristics in outside temperature mode B are determined. , the input time is determined so that the temperature reaches the target time based on the temperature increase characteristics and the predetermined reached temperature of the bed.

At the determined power-on time, power is automatically turned on to the heater of the floor heating system.

Note that each block in FIGS. 1 and 2 operates according to instructions from the timer circuit 6.

(Embodiment of the invention) FIG. 1 shows an embodiment of the invention. 8 in FIG. 1 is an outside temperature detection section, which includes an outside temperature sensor 4 and a temperature measurement circuit 5.
．． It is composed of an A/D converter 7, and measures when a specific periodic signal is transmitted from the timer circuit 6.

31 to 3n are temperature memories, for example, RAM is used as this memory. This memory has a large number of memories, and is designed to sequentially store new information input from 31 in synchronization with the timer circuit 6, and discard old information.

Reference numeral 9 denotes an arithmetic circuit which integrates each time new information is stored in the memories 31 to 3n (FIGS. 2 and 4).

3 is an outside temperature memory, which stores the relationship between the outside temperature mode and the lower limit value of the integrated value as shown in FIG.

This data is obtained as follows. The outside air temperature is detected at regular intervals (for example, every 6 minutes) within a particular time (for example, one day before the start of heat storage), and the detected temperature value is calculated by ii for each cycle.

Each integrated value is classified into five outside temperature modes, for example A to H, and the relationship between each outside temperature mode and the lower limit of the integrated value is stored.

The outside temperature mode in Figure 2 is divided into 5 ranks from A to H.
When the total value is large, that is, when the overall climate is high, it is determined to be ranked high, and when it is low, it is determined to be ranked low.

IO is an outside temperature mode determination unit, which compares the @1 calculation value integrated by the arithmetic circuit 9 with the lower limit value of the a calculation stored in the outside temperature memory 1, and determines which outside temperature mode it corresponds to. That's what I do.

Reference numeral 2 denotes a temperature increase memory, which stores 5tl relationships (FIG. 3) between each of the outside temperature modes A to E in FIG. 2 and the corresponding temperature increase characteristics.

ll is a turn-on time determination circuit, and outside temperature mode determination section 1
New outside temperature mode input from 0 and temperature increase memory 2
By comparison with the temperature rise characteristics stored in the input time determination circuit 11, the temperature rise characteristics in the outside temperature mode input to the input time determination circuit 11 are determined, and the relationship between the predetermined floor temperature and the reached temperature is determined. The power-on time is determined so that the temperature reaches the target time from .

The timer circuit 6 is programmed with a program for operating each block shown in FIG.

(Experimental Example) Figures 5 and 6 are examples of controlling floor heating using late-night electricity using the youngest son method. Figure 5 is for January, and Figure 6 is for March.In both figures, the floor temperature has risen to the set value by the time the room is used; It can be seen that the method of the present invention is effective because there are differences in the degree of power-on and the time at which the power is turned on.

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

(1) Fully automatic that adapts to external dynamics such as the climate and outside temperature during heating, as it uses data such as the climate conditions and outside temperature before heating and compares it with the outside temperature during heating. Underfloor heating is possible. This reduces overheating and underheating, making it possible to provide comfortable heating.

(2) Fully automatic floor heating that adapts to the dynamics of the climate and outside temperature becomes possible, reducing wasted energy used for heating, contributing to energy conservation and significantly reducing running costs (3) Not only is it effective for determining the start time of energization in general floor heating, but it is also particularly effective when using a time-limited power supply system such as late-night electricity, for example, when using a power supply from 0:00 to 8,200, because the heating time is long. .
