AI Technical Summary

Technical Problem

Existing fresh air devices have limited temperature adjustment capabilities and cannot simultaneously consider dehumidification and energy saving, with total heat recovery devices being prone to blockages and seasonal inefficiencies.

Method used

A dual-stage heat exchange system for fresh air devices that includes a first heat exchange system for outdoor environment and a second for exhaust air, with independent operation modes determined by comparing fresh air moisture and temperature to adjust humidity and temperature dynamically, using compressors, four-way valves, and throttling elements to optimize energy efficiency.

Benefits of technology

The system effectively adjusts temperature and humidity independently, reducing excessive treatment and ensuring high-efficiency, energy-saving operation throughout the year, addressing the limitations of single-cycle systems.

Abstract

The present application discloses a method for controlling a fresh air device, an apparatus for controlling a fresh air device, a fresh air device and a storage medium, which involve the technical field of air treatment devices. The fresh air device is provided with a two-stage heat exchange system, and includes a first heat exchange system and a second heat exchange system. By comparing the fresh air moisture content with the target moisture content, and comparing the fresh air temperature with the target temperature; determining the target operation mode of the first heat exchange system and the target operation mode of the second heat exchange system according to the moisture content comparison result and the temperature comparison result, and driving the fresh air device to operate according to the target operation mode of the first heat exchange system and the target operation mode of the second heat exchange system.
