Condensing exhaust heat recovery(Often used in heat pump fresh air/air conditioning integrated machines), the core isAt the same time, recover indoor exhaust energy + air conditioning condensation waste heat, realizeDual energy conservation, accurate temperature and humidity, no cross-pollution, and strong integrationtechnical advantages.

1. Core technical principles

• exhaust air energy recovery: The relatively stable indoor exhaust air (warm in winter and cool in summer) exchanges heat with outdoor fresh air in the heat exchanger,Pre-cooling/preheating fresh air。
• Condensation heat recovery (heat pump cycle)：
  • summer cooling: UseLow-temperature exhaust cooling condenser, reduce the condensation temperature,Improve refrigeration energy efficiency and reduce compressor power consumption。
  • winter heating: UseHigh-temperature exhaust air supplies heat to the evaporator，Increase evaporation temperature, strengthen heating, and reduce frosting。
• air isolation: Fresh air and exhaust airCompletely separated, not mixed，Eliminate cross-pollution。

2. Main technical characteristics

1. Double efficient energy saving, extremely high energy efficiency ratio
   • Recovering exhaust sensible heat/latent heat + condensation waste heat,Significant improvement in comprehensive energy efficiency ratio (COP/EER)。
   • Lower condensation temperatures in summer,Compressor power consumption reduced by 15% to 30%; Reduce defrosting in winter,Heating efficiency increased by 20% to 40%。
2. Stable working conditions in winter and summer and strong environmental adaptability
   • summer: Exhaust cooling condenser,Avoid overheating and high-voltage protection。
   • winter: Exhaust air provides a level heat source,-15 ℃~43 ℃ stable operation, greatly reducing frosting。
   • Fresh air temperature fluctuations are small,More stable air supply。
3. Health safety, no cross-contamination
   • Three channels for fresh air, exhaust air and refrigerantcompletely independent。
   • No core for pollution storage and no penetration,Suitable for hospitals, hotels, and clean places。
4. Integrated structure, simplified system
   • Integrate fresh air, heat exchange, heat pump and exhaust air into one，No outdoor units, no cooling towers, no complex water pipes。
   • The site is only connected to air duct and power supply,Fast installation, small footprint, and few changes。
5. Independent and precise control of temperature and humidity
   • Refrigeration canDeep dehumidification, heating canreheat, realizeconstant temperature and humidity。
   • Xinfengkeindependent processing, not affected by indoor units,Meet high-tech style and high comfort needs。
6. Low noise, reliable operation, long life
   • The condensation pressure is more stable,Compressor load is smoother。
   • Reduce frosting and defrosting cycles,Lower component loss。
7. Run all year round, with a wide range of application
   • Hotels, residences, offices, hospitals, schools, shopping malls, etc.Need a lot of fresh air + energy conservationplace.

3. Comparison with traditional total heat/sensible heat exchange

• total heat exchanger: Only recover exhaust energy,Cannot deeply control and dehumidify, and the fresh air temperature fluctuates greatly。
• Condensing exhaust heat recovery：Recovery of exhaust air + condensation heat, active temperature adjustment by heat pump, constant temperature and humidity, no cross-pollution, efficient and stable in winter and summer。
