It is aired.

As such, as the air conditioner discharges contaminated indoor air to the outside and supplies fresh air to the room, the performance of the air conditioner can be said to be an important factor in determining indoor air quality and environment. Accordingly, it is very important to measure the performance of the air conditioner in real time and provide the results to the user in advance so that the risk factors can be recognized.

Check the performance of the air conditioner, for example, whether the ventilation volume of the air conditioner satisfies the legal standard (over 0.5 times per hour), what is the heat exchange rate, whether the performance and replacement cycle of the filter has arrived, whether the concentration of fine dust and the indoor air quality are in real time, etc. In doing so, it is most important to determine the risk factors and diagnose the performance degradation of the air conditioner to find solutions such as replacement of parts such as filters or repair of the air conditioner.

However, there has been no difficulty in recognizing a potential risk factor since there is no means to determine the performance degradation of the air conditioner.
