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.
