Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a humidity control signal output device that generates a start/stop control signal for humidity control equipment such as a humidifier, a humidifier, and a heat exchanger.

BACKGROUND OF THE INVENTION In recent years, there has been increasing interest in health and comfort, and as a result, emphasis has been placed on suppressing the growth of mold on surfaces such as walls and ceilings.

The conventional humidity control signal output device used to suppress the growth of mold is a humidifier that detects the humidity in the indoor space and removes it.

It controlled the on/off of humidity control devices such as heat exchangers and ventilation fans.

In this case, even if humidity is controlled during heating during the winter, condensation may form on the walls and ceilings of buildings, which can lead to mold growth. As a result, there may be adverse effects such as generation of bad odor and asthma, so there has been a demand for an appropriate humidity control signal output device for controlling humidity control equipment.

Hereinafter, a conventional humidity control signal output bag device as described above will be described with reference to the drawings. FIG. 5 shows a conventional humidity control signal output device. The humidity control signal output device is composed of an indoor humidity detection means 2 and a control means 4a, and controls the operation of the humidity adjustment device 6. The indoor humidity detection means 2 detects the indoor relative humidity Hr.
is detected and converted into an electrical signal, and the output signal is transmitted to the control means 4a.

The control means 4a compares the indoor humidity Hr with the set value and turns on/off the power supply of the dehumidifier, which is the humidity adjusting device 5 (not shown), to maintain the indoor humidity Hr at the set value. Figure 6 shows the relationship between the dehumidifier's on/off operation and the indoor relative humidity. The indoor relative humidity is the first set value L1
When the temperature rises, the humidity control signal turns ON, and the dehumidifier starts to operate and dehumidify.

Furthermore, when the indoor relative humidity becomes lower than the second set value L2, the dehumidifier stops operating. In this way, the relative humidity in the room was maintained at a constant value near the set value.

Problems to be Solved by the Invention However, with the above configuration, it is difficult to set humidity values in a continuous manner. If you set the humidity value too low, you are more likely to catch the flu, and if you set it too high, the surface temperature of parts of the heated room that are easily affected by the outside temperature, such as walls and ceilings, will decrease due to the drop in outdoor temperature in winter. The problem is that the relative humidity of the air that comes into contact with those areas decreases and the relative humidity of the air that comes into contact with those areas increases, resulting in the growth of mold in those areas and the resulting mold odor and increased susceptibility to asthma. Ta.

The present invention takes into consideration the above-mentioned conventional problems, and provides a humidity control signal that outputs a humidity control signal to control the start/stop of a humidity control device in order to prevent dew condensation on walls, ceilings, etc. and suppress the growth of mold. The purpose is to provide an output device.

That is.

Operation In the above configuration, the three detection means detect and output outdoor temperature, indoor temperature, and indoor humidity, respectively. The signals of the outdoor temperature and the indoor temperature are input to a surface temperature calculation means to calculate and output the surface temperature of walls, ceilings, etc., and the signals of the indoor temperature, indoor humidity, and surface temperature are input to the surface temperature calculation means It is input to a calculation means, and the surface humidity of walls, ceilings, etc. is calculated and output. Next, the determination means inputted with the surface temperature and surface humidity signals determines whether the surface environment such as walls and ceilings satisfies the growth conditions for mold, and based on the determined results, sends an operation control signal to the humidity adjustment device. It will be issued.

and the signal of the surface temperature calculation means 6 are input, and the output signal of the first logical product calculation means 1o is 1, that is, the surface temperature T of the wall, ceiling, etc. is the first comparison temperature value T1 and the second comparison temperature value T1. When the temperature is between the comparison temperature value T2, the humidity value at the limit of the mold growth area is calculated from the signal from the surface temperature calculation means 6 using equation (2).

The first humidity determining means 13 receives the signal from the surface humidity calculating means 12, compares this signal with a first comparison humidity value H1 set internally, and outputs the result.

The second logical product calculating means 14 calculates the logical product of the positive signal of the first temperature determining means 8 and the signal of the first humidity determining means 13. If the result of the calculation is 1, it is a wall.

It can be seen that the surface temperature T8 of the ceiling, etc. is higher than the first comparison temperature value T1, and the surface humidity H8 of the walls, ceiling, etc. is also higher than the first comparison humidity value H1, which indicates that it is in the mold growth area. .

If the condition of T1 is not satisfied, output the result as 1 and proceed to the next step. If the conditions are met, jump to the 12th S step. In the 78th step, the surface temperature of walls, ceilings, etc. T8
and the second comparison temperature T2 are compared and determined by the second temperature determining means 9, and if the condition TB>T2 is satisfied, the result is output as 1,
Proceed to next step. If the conditions are not met, hatch first. In the 88th step, the output signal of the 68th step and the signal of the 78th step are logically multiplied by the first logical product calculation means 10, and if it is 1, the surface temperature TB of the wall, ceiling, etc. is the first comparison temperature T1. and the second comparison temperature T2.

In the 98th step, using the signal of the surface temperature T8 of the wall, ceiling, etc., the comparison standard humidity calculation means 11 calculates the equation (2).
Determine the comparison standard humidity HC. In the first OS step, the surface relative humidity H8 of walls, ceilings, etc. and the comparative reference humidity H
The second humidity determination means 15 compares and determines H,
)H, the result is output as 1. This means that the conditions are such that mold can grow. If the conditions are not met, return to the first step. In the 129th step, the first humidity determining means 13 compares and determines the surface relative humidity H8 of walls, ceilings, etc. and the first comparison humidity value H1, and outputs the result as 1 if the condition H8>H1 is satisfied. In the 133rd step, the second logical product calculating means 14 performs a logical product of the signal of the sixth step and the signal of the 123rd step. If it is 1, the surface temperature T of walls, ceilings, etc. is the first
The comparison temperature T1 is higher than that, and the surface relative humidity H8 of the walls, ceiling, etc. is also higher than the comparison reference humidity H0.

This also means that there are conditions where mold can grow. In the 118th step, the 1st oS step and the 138th
The logical sum calculation means 16 calculates the logical sum of the step signals and outputs the result as a control signal.
