Ventilation system, control method thereof and computer readable storage medium

Abstract

The invention provides a ventilation system, a control method thereof and a computer readable storage medium. The ventilation system involves a plurality of indoor units, an outdoor unit and a plurality of reheating parts, wherein the indoor units communicate with the outdoor unit, and coil pipes of the reheating parts communicates with an outdoor heat exchanger of the outdoor unit. The control method for the ventilation system comprises the following steps that the outlet air temperature of the plurality of reheating parts is obtained, and the output capacity of the reheating parts is determined; the opening degrees of valve bodies of the plurality of indoor units are obtained, and the output capacity of the indoor units is determined; and according to the output capacity of the reheatingparts and the output capacity of the indoor units, the opening degree of a valve body of the outdoor unit is controlled to adjust the temperature of the reheating parts. According to the control method of the ventilation system, the opening degree of the valve body of the outdoor unit is adjusted according to the output capacity of the indoor units, then the temperature of the reheating parts ischanged to ensure that the ventilation system outputs the appropriate temperature, and the reliability and the stability of the ventilation system are 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...

AI Technical Summary

Problems solved by technology

At this time, when the reheating element has no adjustable valve body, when the medium pressure cannot be controlled, it will often cause insufficient or excess capacity of the reheating element, which will cause the outlet air temperature of the fresh air system to fail to meet the user's requirements. demand, which seriously affects the reliability and product stability of the fresh air system
