Description

Air conditioning duct system having a device for measuring pollution level

The present invention relates to an air conditioning duct system capable of measuring the degree of air pollution, and more particularly, in the process of discharging and sucking indoor air or outdoor air (outdoor air), the operation according to the degree of pollution causes the rapid discharge of polluted indoor air and fresh outdoor air. It relates to an air conditioning duct system capable of measuring air pollution to enable inflow.

In general, a duct having a supply/exhaust function for providing a comfortable environment by filtering indoor polluted air is installed in a multi-family house such as an apartment.

On the other hand, these ducts are formed so that outdoor air is introduced from the outdoors, and are connected by a duct that communicates indoors and outdoors with a ventilation device formed so that indoor air is discharged to the outside, so that indoor air is discharged to the outside and outdoor air is discharged to the outside. It is formed to be introduced into the room.

However, the conventional duct as described above implements a simple circulation method of discharging indoor air to the outside or introducing outdoor air into the room. There was a serious problem of influx into the room.

Normally, it has an air conditioning system that forcibly discharges polluted indoor air to the outside through a duct and introduces fresh air from the outside into the room. There was a problem that could be worse than the air in the room.

And if the indoor air is heavily polluted, it should be discharged to the outside in a short time, but the blower formed in the duct was insufficient. Therefore, there was a need for a forced blowing means that can be used whenever necessary.

The present invention was devised to solve the above problems, and in discharging indoor polluted air to the outside or introducing outdoor outdoor air into the room, it always provides smooth indoor air quality in response to the pollution degree of the air. It is an object of the present invention to provide an air conditioning duct system capable of measuring the air pollution level to enable the improvement of a comfortable indoor environment according to the improvement of the duct function, such as enabling circulation.

When introducing air from outside, if air with a high degree of pollution enters, the filter automatically operates to filter the outside air.

By conveniently displaying the pollution level of the air discharged from the indoor and the pollution level of the air coming in from the outside, the user can choose to block the inflow of the outdoor air or let it pass through the filter. If the degree of pollution is severe, it is intended to be configured to be discharged within a short period of time.

As a specific means for achieving the above object, in the duct system,

a first measurement sensor installed inside the indoor side of the duct to measure indoor air pollution;

a second measuring sensor installed inside the outdoor side of the duct to measure the pollution level of the incoming outside air;

a forward/reverse type ventilation fan installed inside the duct to enable forced exhaust of indoor air and forced inflow of outside air;

a variable device that is formed on the outside from the ventilation fan inside the duct to control and filter the amount of air discharged from the room and forcibly introduced into the outside air; and

This can be achieved by configuring the display panel to include a control unit having a switch for controlling the formation and operation of the ventilation fan and the variable device so as to display the air pollution level measured by the first and second measurement sensors.

As described above, in the air conditioning duct system capable of measuring air pollution according to the present invention, a first measuring sensor capable of measuring indoor air pollution is formed on the indoor side of the duct, and a second measuring sensor capable of measuring the pollution degree of outdoor air is formed and measured on the outdoor side. It is possible to quickly respond according to the level of air pollution, such as the display of the level of pollution. In particular, it is possible to quickly discharge contaminated air through a ventilation fan and supply fresh outdoor air. It is possible to obtain the effect of improving the performance and improving the always comfortable indoor environment.

When outside air is introduced, the filter is automatically operated when the concentration of fine dust and the amount of ultra-fine dust are at dangerous levels, purifying the outside air and introducing it into the room, so effective ventilation is possible.
