Intelligent clean room energy saving technology
1. Low section wind speed design
The new surface wind speed is the speed of air passing through the filter or heating/cooling coil in the air external management component. Larger air external management, larger filter and coil area consumes less fan energy, and smaller fans and motors can be used. The small fan adds less heat to the air, reducing the difficulty of cooling. Small thickness coils are easier to clean and more efficient, so the temperature of the frozen water can be higher. The filter works better and has a longer life at low cross section wind speed.
2. Number of air changes
Under the premise of maintaining cleanliness, the reduction of air flow rate can reduce construction and energy consumption costs, and the size of the fan can be reduced by 50% if the number of air changes is reduced by 20%. Clean air is more important than energy savings, but recent research has shown that cleaning costs can be reduced. There is no consensus on the number of air changes, many principles are outdated, are based on old concepts, and use inefficient air filters. The survey showed that the recommended number of air changes for clean rooms under ISO Level 5 standards ranged from 250 to more than 700.
3. Motor efficiency
The motor consumes most of the electricity in the clean room, and the continuous operation of the motor consumes a lot of electricity per eye, which can improve efficiency and adjust the size locally. After renovation, the economic effect is mostly good. A few percentage points increase in efficiency can increase profits. Using a high-quality and efficient motor doesn't have to cost too much. High efficiency means minimum, minimizing the load before changing the size of the motor. Variable speed drive (VSD) can improve the efficiency of operation when the output changes.
