Data center heat recovery: With the rapid development of data centers, their energy consumption and heat dissipation issues are becoming increasingly prominent. Recovering the waste heat generated by data center servers and other equipment for heating, hot water supply, or preheating of other industrial processes in surrounding buildings, achieving green and energy-saving operation of data centers.
Thermal management of electric vehicle batteries: During the charging and discharging process of electric vehicle batteries, a large amount of heat is generated. Developing an efficient battery thermal management system to recover the waste heat generated by the battery for energy supply to in car heating or other auxiliary equipment can not only improve the performance and lifespan of the battery, but also enhance the overall energy utilization efficiency of electric vehicles.
Industrial waste heat driven refrigeration system: Utilizing industrial waste heat to drive absorption refrigeration, adsorption refrigeration and other systems, providing cooling capacity for the cooling needs in industrial production processes. This method can reduce the energy consumption of traditional electric refrigeration systems, achieve cascade utilization of waste heat, and improve the comprehensive utilization efficiency of energy.
Typical Application Environments
Heat recovery is valuable wherever a building or process expels warm, stale air while drawing in cold or hot fresh air. Common sites include factory make-up air systems, commercial kitchens, paint booths, drying rooms, laboratories, and cleanrooms. In each case the exhausted air still holds usable thermal energy, and capturing it reduces the heating or cooling demand placed on the primary plant.
Matching the Unit to the Duty
The right selection starts with the air volume, the temperature difference between streams, and the cleanliness of the exhaust. Clean, steady flows suit plate exchangers; humid or dusty exhaust may need a rotary wheel with purge or a unit arranged for easy wash-down. Pressure drop must stay within the fan curve, and the core material must resist any contaminants present in the airstream.
Integration Tips
For the New application areas of waste heat recovery duty, position the exchanger so the exhaust is filtered before it reaches the core, and provide condensate drainage where the supply side may drop below the dew point. Balanced supply and exhaust fans keep the building neutral in pressure, which protects indoor air quality and process control. A bypass damper lets the system free-cool in mild weather.
Frequently Asked Questions
Can it handle greasy kitchen air? Yes, with a rotary wheel and a wash cycle, though the exhaust should first pass a grease filter. Will it cause condensation? Some condensate is normal in winter; provide a drain or a defrost strategy on the supply side.
