1。 Fresh air system also has a magic function of heat exchange! For example, in winter, outdoor temperature is - 10 degrees, while indoor temperature is 20 degrees, the difference between indoor and outdoor temperature is comparatively large。 In order to ventilate, you may open the windows directly, and the outdoor cold air enters the room directly。 This will reduce the indoor temperature, increase the energy consumption of the air, and make people feel uncomfortable。
2. If you have a fresh air system installed in your home, you can open the fresh air system directly without opening windows. When fresh air is used, the outdoor cold air is sucked into the room and the turbid heat in the room is discharged out of the room. These two air streams will penetrate through the hot exchange core of the fresh air system and pass through it contactlessly. The turbid heat flow discharged from the room will automatically heat the cold flow into the room and complete the energy exchange. This not only replaces indoor air, but also recovers heat energy. The indoor temperature will decrease slightly, but it can still be maintained at about 18 degrees. The opposite is true in summer. It improves the air quality of living environment.
3. Therefore, central air conditioning and fresh air system are two indispensable indoor systems. One is to give you warm and cold, the other is to improve indoor air quality, which is two concepts, respectively, to deal with two problems in our residential environment. Unfortunately, nowadays, many people do not know the difference between the two, often mistakenly assume that air conditioning will be fully processed.
