Do the fresh air system and central air conditioning need to be turned on at the same time?

Many people have questions about this problem. If the central air conditioner is turned on and the fresh air system is turned on, wouldn’t it be possible to exhaust the cold and hot air produced by the central air conditioner to the outside?

In fact, there is no conflict between the central air conditioning and the fresh air system. The current fresh air system has a high-efficiency heat recovery system, which stores the energy of the exhausted air during exhaust, so that the temperature difference between the incoming air and the indoor air is reduced to a small amount.

Generally, central air conditioning mainly solves the problem of indoor heating and cooling. For the sake of energy saving, air conditioning is to cool or heat the air in a confined space, and generally does not introduce air from the outside; and the fresh air system solves the problem of indoor air quality. Outdoors, fresh air is sucked into the room, filtered by the core purification system, and then entered into the room. At the same time, the dirty air in the room is discharged to the outside through the air outlet.

Therefore, under the premise of not opening the windows, in order to achieve a good replacement of indoor air, users who have installed a household central air conditioner are better to install a fresh air system.
