Temperature Control and Dehumidification Solution
Mushroom cultivation requires precise control of temperature, humidity, and air quality throughout different growth stages. Continuous ventilation is essential to remove excess moisture and carbon dioxide, but traditional direct air exchange often causes large temperature fluctuations and high energy consumption. Integrating an air-to-air heat exchanger into the fresh air system provides an effective solution for simultaneous temperature control and dehumidification in mushroom growing rooms.
Challenges in Mushroom Room Ventilation
Mushroom growing facilities typically face the following issues:
Continuous demand for fresh air supply
High humidity exhaust air with significant moisture content
Direct ventilation leading to unstable indoor temperatures
High heating demand in winter and increased cooling load in summer
Difficulty maintaining stable humidity levels, affecting yield and quality
An energy-efficient ventilation solution is required to balance fresh air supply, moisture removal, and thermal stability.
Working Principle of the Air-to-Air Heat Exchanger
The air-to-air heat exchanger enables energy transfer between exhaust air and incoming fresh air without air mixing:
-
Warm, humid air is extracted from the mushroom room
-
Exhaust air and outdoor fresh air pass through the heat exchanger core
-
Thermal energy is transferred through the heat exchange surfaces
-
The two air streams remain completely separated, preventing contamination
-
Preheated or precooled fresh air enters the growing room with reduced thermal and moisture load
This process allows ventilation, temperature regulation, and dehumidification to operate simultaneously.
Temperature Control and Dehumidification Performance
Temperature Regulation
During winter operation, heat from the exhaust air is recovered to preheat incoming fresh air, significantly reducing heating demand.
During summer operation, incoming air is precooled, lowering the cooling load of the system.
Moisture Removal
Continuous exhaust of high-humidity air effectively reduces indoor moisture levels while maintaining stable room temperature, preventing excessive condensation and environmental stress on mushroom growth.
