Abstract

PURPOSE:To enable the controlling of an air conditioner having a function of purification. ventilation or the like by setting at least one kind out of an NOX gas sensor and an SOX gas sensor to gain a specified concentration based on information obtained. CONSTITUTION:An NOX gas or an SOX gas generated within a space 11 to be air-conditioned is detected with a gas detecting section 13a made up of at least of one kind out of an NOX gas sensor and an SOX gas sensor. An output value obtained is sent to an air conditioning controller 16a. The air conditioning controller 16a is made up of a circuit section to compare the output value of the gas detecting section 13a with a reference value set to a certain value and a circuit section to control an external load. When the output value of the gas detecting section 13a exceeds the reference value, a ventilator 12 or a cleaner 14 is operated singly or simultaneously to gain a specified concentration in air conditioning.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning method using a gas sensor.

[0002]

BACKGROUND ART conditioning method using a conventional semiconductor gas sensor, there is a variety of proposals, but both H ₂ or C
The reducing gas such as O is detected by the gas sensor, and the air conditioner is controlled based on the signal from the sensor.
On the other hand, NO recently specified by the Air Pollution Control Law
_Although there is an increasing need for air conditioning control methods based on the concentration of _X gas or SO _X gas, small and inexpensive NO _X gas,
This has not been achieved because there is no means for detecting SO _X gas.

[0003]

DISCLOSURE OF THE INVENTION The present invention uses a semiconductor gas sensor capable of detecting the NO _x gas concentration and the SO _x gas concentration determined by the Air Pollution Control Act, and uses the pollutants NO _x gas and SO _x gas. We propose a method to detect air conditioner and to air-condition a predetermined space, for example, a moving space such as a car and a fixed space where animals and plants such as houses live.

[0004]

In order to solve the above problems, the present invention provides NO _X inside or outside a predetermined space.
At least one type of gas sensor is installed between the gas sensor and the SO _X gas sensor, and based on the information obtained from the sensor, a predetermined concentration is set, so that it is possible to control an air conditioner having a function such as purification or ventilation. Further in a given space and each installed at least one gas sensor among of the NO _X gas sensor and SO _X gas sensor outside the predetermined space, as an information source output signals of the installed gas sensor, performs the appropriate algorithm processing, purification, It is possible to control an air conditioner that has functions such as ventilation or sealing.

[0005]

In the present invention, N determined by the Air Pollution Control Law
At least one type of semiconductor gas sensor capable of detecting the O _X gas concentration or the SO _X gas concentration is used to detect the NO _X gas and SO _X gas, which are pollutants generated inside and outside the predetermined space, and to detect the predetermined space at the predetermined concentration. It became possible to use the air conditioning method.

EXAMPLES Examples of the present invention will be described in detail. 1, 2 and 3 show the concept of the present invention.

Embodiment 1 In FIG. 1, the NO _x gas or SO _x gas generated in the air-conditioned space 11 is detected by a gas detector 13a which is composed of at least one type of gas sensor of NO _x gas sensor and SO _x gas sensor. The obtained output value is sent to the air conditioning controller 16a. The air conditioning controller 16a includes a circuit unit that compares a reference value set to a certain value with the output value of the gas detection unit 13a and a circuit unit that controls an external load,
When the output value of the gas detection unit 13a exceeds the reference value,
The ventilation device 12 or the purification device 14 is operated individually or simultaneously to perform air conditioning so as to achieve a predetermined concentration.

Embodiment 2 In FIG. 2, the NO _X gas or SO _X gas generated outside the air-conditioned space 11 is detected by the gas detection unit 13b composed of at least one kind of gas sensor of NO _X gas sensor and SO _X gas sensor. The obtained output value is sent to the air conditioning controller 16b. The air conditioning controller 16b includes a circuit unit that compares a reference value set to a certain value with the output value of the gas detection unit 13b and a circuit unit that controls an external load,
When the output value of the gas detection unit 13b exceeds the reference value,
Ventilation device 12, purification device 14 or outside air introduction device 15
Are operated individually or simultaneously to perform air conditioning to a predetermined concentration.

Embodiment 3 In FIG. 3, a gas detector 13a and an air conditioning controller 16a are installed in the air-conditioned space 11, and a gas detector 13b is installed outside the air-conditioned space 11. Here, the output value of the gas detection unit 13a,
The output value of the gas detection unit 13b and the reference value set to a certain value are subjected to an appropriate algorithm processing by the air conditioning controller 16a, and the ventilation fan 12, the purifying device 14 or the outside air introducing device 15 is operated alone or simultaneously according to the result.

Further, the ventilation fan 12, the purifying device 14 or the outside air introducing device 15 shown in this embodiment can be wirelessly controlled without being connected to the air conditioning controller 16a and the air conditioning controller 16b.
