Abstract

The invention provides a fresh air system, a control method of the fresh air system and a computer readable storage medium. The fresh air system comprises a valve body and a reheating part, wherein the valve body communicates with a coil pipe of the reheating part; and the control method of the fresh air system comprises the following steps of acquiring operating parameters of the fresh air systemand outdoor environment temperature; and controlling the opening degree of the valve body to adjust the temperature of the reheating part based on fresh air system operation refrigeration mode and under the condition that the operation parameters and the outdoor environment temperature meet the first execution condition. According to the control method of the fresh air system, the opening degreeof the valve body is controlled to adjust the temperature of the reheating part, it is guaranteed that the air outlet temperature of the fresh air system is proper, the air outlet temperature of the fresh air system is guaranteed while the requirement of an indoor user for fresh air replacement is met, the indoor environment temperature is controlled to be within a reasonable range, high-pressureviolent fluctuation of the fresh air system is avoided, and the air outlet stability and comfort of the fresh air system are effectively improved.

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 economic development, users have increasing requirements for air-conditioning systems, especially for indoor air quality. The fresh air system came into being, but the indoor unit of the fresh air system is very different from the ordinary ducted unit or other types of indoor units. The return air of the indoor unit of the fresh air system is the fresh air outside, which also leads to the The return air temperature is consistent with the external environment. Even if the indoor unit is running, the return air temperature will not change, which will greatly affect the multi-connected system to adjust the indoor temperature of the indoor unit. Therefore, it is necessary to turn on the reheat...
