Abstract

The present invention provides a fresh air system, a control method thereof, and a computer-readable storage medium, wherein the fresh air system includes a valve body and a reheating element, the valve body is communicated with a coil of the reheating element, and the control method of the fresh air system includes: obtaining The operating parameters of the fresh air system and the outdoor ambient temperature; when the fresh air system operates in the cooling mode, and the operating parameters and the outdoor ambient temperature satisfy the first execution condition, the opening of the valve body is controlled to adjust the temperature of the reheating element. The control method of the fresh air system proposed by the present invention controls the opening of the valve body to adjust the temperature of the reheating element, so as to ensure that the outlet air temperature of the fresh air system is suitable. The outlet air temperature should be controlled within a reasonable range to prevent the high pressure fluctuation of the fresh air system, and effectively improve the air outlet stability and comfort of the fresh air system.

Description

technical field [0001] The present invention relates to the technical field of fresh air ventilation, in particular, to a control method of a fresh air system, a fresh air system and a computer-readable storage medium. Background technique [0002] With the change of the times and the rapid development of the economy, the requirements of users for air conditioning systems are increasing, especially the requirements for indoor air quality are getting higher and higher. The fresh air system came into being. However, the indoor unit of the fresh air system is very different from the ordinary duct unit or other types of indoor units. The return air of the indoor unit of the fresh air system is the outdoor fresh air, which also leads to the The return air temperature is the same as the outside environment. Even if the indoor unit is running, the return air temperature will not change, which will greatly affect the indoor temperature adjustment of the indoor unit by the multi-conn...
