Air to water Heat pump Energy ventilation system with bypass
Short Description:
This ERV with heating and cooling is suitable for cold area buildings
• By pass function, when the temperature difference between day and night is large in summer, cool air can be quickly introduced into the room.
• The air to water pump water pipe can be connected, and the ERV ventilation temperature can be precooled and preheated by the energy of the air to water pump to improve the fresh air comfort.
• It provides healthy and comfortable fresh air while achieving maximum energy savings, heat recovery efficiency is up to 80%.

1, test site coil water inlet temperature: 32.3℃, outlet temperature: 22.1℃;
2. According to the enthalpy difference of the inlet and outlet air of the coil, the heat load of the coil is calculated.
3. Inquire the standard Yinchuan atmospheric pressure value: 88390pa
Conclusion
When the municipal hot water heating is not lower than 30℃, the preheating capacity of the three-pipe new fan (with preheating coil) at high/medium/low speed is:
High speed 1797W, medium speed 1637W, low speed 1347W
Meet the preheating requirements of fresh air.
