Design performance description:
a.Exhaust system installed in a large space.
b.The power supply of the negative pressure exhaust fan is designed to use photovoltaic power DC288V as the main power supply.If the sunshine is insufficient or there is no sunshine, the system can be manually switched to a dual power supply configuration of AC220V power supply, and the system does not need to install a battery pack.
c. The power of the photovoltaic panel configured in the system is 120% of the disc motor of the shaft power of the device's motor.
d. The system requires that the weak sunlight in the early morning can start to exhaust the air at a low speed to avoid heat accumulation in the space. When the sun is sufficient, the system can run at full speed and automatically exhaust the air at high speed.
e. When the system is powered by photovoltaic panels, the speed and exhaust volume of the system all depend on the intensity of sunlight.
