Problems solved by technology

[0003] In related technologies, the fresh air system is usually a full heat exchanger type, which uses the waste cold / waste heat exhausted to the outdoor air to cool / heat the fresh air, but this type of fresh air system has a complex structure and high cost
The fresh air system without a full heat exchanger cannot cool the fresh air entering the room
In addition, when the humidity in the ventilation duct of the fresh air system is high, mildew is prone to occur in the ventilation duct of the fresh air system

Abstract

The present invention proposes a fresh air system control method, device, and fresh air system. The control method of the fresh air system includes: judging whether the concentration of indoor carbon dioxide is less than a preset concentration threshold; if so, the first humidity is equal to or greater than the second humidity and The sum of the preset difference humidity will control the ultrasonic atomizer to close, turn on the fan, and set the gear when the fan is turned on to the set gear; if not, turn on the fan, and determine the fan according to the concentration of carbon dioxide. The gear when it is turned on; according to the gear when the fan is turned on, the cooling load required for the fresh air cooling of the fresh air system is obtained; the gear of the ultrasonic atomizer is controlled according to the cooling load and the temperature of the cooling water. The control method and device of the fresh air system and the fresh air system of the present invention can accurately control the opening of the fresh air system and the gear position when it is turned on, can prevent mildew in the ventilation pipe; can accurately reduce the temperature of the fresh air supply; at the same time, the method also The invention has the advantages of simple realization and low cost.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a control method and device for a fresh air system and the fresh air system. Background technique [0002] With the improvement of people's living standards, the demand for fresh air is becoming stronger and stronger. [0003] In the related art, the fresh air system is usually a total heat exchanger type, which cools / heats the fresh air by using the residual cold / heat discharged to the outdoor air, but this type of fresh air system has a complex structure and high cost. The fresh air system that does not include a full heat exchanger cannot cool the fresh air entering the room. In addition, when the humidity in the ventilation duct of the fresh air system is high, mildew is prone to occur in the ventilation duct of the fresh air system. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at lea...
