Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner that uses an adsorbent to improve air quality.

BACKGROUND OF THE INVENTION In recent years, air conditioners that dehumidify moisture and remove odors from the air emitted indoors have come into use.

Conventionally, as shown in FIG. 4, this type of air conditioner dehumidifies indoor air by passing the indoor air through an adsorbent 20 and supplying dry air from which watermelon has been removed indoors. (For example, Japanese Unexamined Patent Publication No. 63287532) There are also some systems in which outside air is brought into contact with the adsorbent 20 to remove odor molecules and then supplied indoors.

(For example, Japanese Unexamined Patent Publication No. 55-121336) Problems to be Solved by the Invention However, in such conventional devices, the heat of adsorption generated during adsorption directly enters the room, so the indoor temperature varies depending on the amount of heat. There is an inconvenience in that the temperature rises, causing discomfort.

The present invention solves the above-mentioned problems. By cooling the air supplied indoors by exchanging heat with outdoor air and changing the cooling capacity, the present invention provides air with dehumidifying and heating functions suitable for the season and region. The purpose is to provide a harmonizing device.

Means for Solving the Problems In order to achieve the above object, the present invention includes an adsorbent that selectively adsorbs at least one type of gas molecule in the air, and a method in which indoor air to be treated is brought into contact with the adsorbent. Equipped with an air conveying means such as a blower for supplying air indoors, a cooling means for exchanging adsorption heat generated during adsorption with outdoor air for cooling, and a temperature sensor for detecting the indoor air temperature,
and a control device that controls the cooling capacity of the cooling means in accordance with the output of the temperature sensor.

Effect The present invention has the above-described configuration, and by controlling the degree of heat exchange of adsorption heat with outdoor air according to the indoor temperature, for example, when the room temperature is low and heating is required, the adsorption heat is transferred indoors. supply At this time, the capacity of the cooling means is controlled to appropriately adjust the room temperature. Conversely, if the room temperature is high, heat is exchanged with outdoor air and the adsorption heat is discharged outdoors. Therefore, in addition to the function of improving indoor air quality, it also has the function of controlling room temperature.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. As shown in the figure, 1 is the main body of the air conditioner, with an indoor air inlet 2 and an indoor air outlet 3 on the indoor side.
An outdoor air suction port 4 and an outdoor air discharge port 5 are provided on the outdoor side, and the main body l is arranged so that the air sucked from the indoor air suction port 2 passes through the outdoor side and is discharged from the indoor air discharge port 3.
A partition wall 6 is provided inside to form an air flow path. In the indoor air flow path of the main body 1, there is an adsorbent 7 made of zeolite or the like, an air conveying means consisting of a first blower 8 that supplies indoor air to the adsorbent 7, and a thermistor that detects the temperature of the indoor air. A temperature sensor 9 consisting of, etc. is provided. On the other hand, in the outdoor air flow path from the outdoor air inlet 4 to the outdoor air outlet 5, a cooling means is provided which is cooled by a second blower 10 and a heat exchanger 11 that exchanges heat between indoor air and outdoor air. It is set up. The control device 1 controls the rotation speed of the second blower [110] according to the output of the temperature sensor 9, and controls the cooling capacity of the heat exchanger 11.
2 are provided.

In the above configuration, when the air conditioner is operated, the air to be treated A is sucked in from the indoor air suction port 2 by the first blower 8, passes through the adsorbent 7, and pollutants such as water vapor and carbon dioxide in the air are adsorbed. , clean, dehumidified air is created.

At this time, heat of adsorption is generated in the adsorbent 7, and the heated air passes through the heat exchanger II. On the other hand, the second blower 1
0, the air sucked in from the outdoor air suction port 4 is blown to the heat exchanger 11 and heat exchanged with the heated indoor air, and the indoor air is cooled and purified from the indoor air discharge port 3. The air B is diffused into the room.

Then, the room temperature is detected by a temperature sensor 9 provided on the indoor side, and the rotation speed of the second blower 10 is controlled by the control device 12 according to the detected value, and the degree of heat exchange in the heat exchanger 11 is adjusted. It is something that

In other words, when the room temperature is low, the second
The rotation speed of the blower 10 is lowered to lower the degree of cooling of the indoor air whose temperature has increased due to heat of adsorption in the heat exchanger 11, and the indoor air whose temperature has increased is discharged from the indoor air outlet 3 to cool the indoor air. When the room temperature is high, the rotation speed of the second blower 10 is increased to increase the degree of cooling in the heat exchanger 11 of the indoor air whose temperature has further increased due to the heat of adsorption, and the heat of adsorption is released to the outside. , the air with an excessively elevated temperature is controlled so as not to be discharged from the indoor air outlet 3.

Note that the rotation speed control of the second blower 10 is performed at a certain set room temperature 1. as shown in FIG. and off-on control with a differential at t2.

As described above, according to the air conditioner according to the embodiment of the present invention,
By detecting the room temperature with the temperature sensor 8, the degree to which the adsorption heat of the adsorbent 6 is supplied into the room is controlled by the capacity of the cooling means, so in addition to the function of improving the indoor air quality, the room temperature can also be controlled. This contributes to heating, especially in winter, resulting in high energy savings.

In addition, if the room is airtight and has a small heating load, the room temperature can be controlled, dehumidified and air purified at the same time without the use of heating equipment, making it possible to achieve healthy and energy-saving air conditioning with small equipment.

Effects of the Invention As described above, according to the present invention, the adsorption heat generated when the adsorbent adsorbs air pollutants such as water vapor and carbon dioxide in the indoor air to be treated is transferred to the outdoor air by the cooling means. The degree of adsorption heat supplied indoors during heat exchange is controlled according to the indoor temperature, so in addition to dehumidification and air purification functions, it also has a heating function that allows control of indoor temperature.

Therefore, the heat of adsorption is effectively utilized depending on the season, contributing to heating and achieving energy savings.

In addition, in recent years, housing performance has improved and the number of houses with high airtightness and low heating load is increasing.With the air quality improvement function and room temperature control MS function, a single unit can achieve a healthy and comfortable air effect. be able to.
