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 reheating element, and the control method of the fresh air system includes: acquiring a temperature change rate of a coil of the reheating element; rate, and control the fresh air system for drainage. Based on the detection of the temperature change rate of the coil of the reheating element, the invention judges whether there is liquid accumulation inside the coil, and controls the fresh air system to discharge the liquid when there is liquid accumulation in the coil, which can effectively avoid the accumulation of liquid refrigerant in the Reheat the inside of the coil and ensure that more refrigerants participate in the work of the fresh air system to improve the reliability and comfort of the fresh air system.

Description

Technical field [0001] The present invention involves the field of fresh air gas exchange technology. Specifically, it involves a new air system control method, fresh air system, and computer readable storage medium. Background technique [0002] With the changes of the times and the rapid development of the economy, users' requirements for air -conditioning systems have increased, especially for indoor air quality. The fresh air system came into being. However, the indoor machine of the fresh air system is very different from the ordinary duct or other types of internal machines. The return air temperature is the same as the outer environment. Even if the indoor machine is running, the return temperature will not change, which will greatly affect the adjustment of the indoor temperature of the indoor machine. , Increase indoor comfort. [0003] However, when the hot parts are not turned on, the internal hot parts are easy to accumulate refrigerant, causing the oil depository to ...
