Demand for purification fans in energy storage laboratories

Do semiconductor cleanrooms consume a lot of fan power?

The semiconductor cleanrooms consume lots of fan power energy for the demand of indoor thermal and cleanliness environment. Therefore, this study focuses on the performance of the ventilation system in semiconductor cleanrooms and its relationship with the heating/cooling process, filtration process, and indoor cleanliness conditions.

Can a ventilation system reduce fan power consumption in a semiconductor cleanroom?

The proposed ventilation system can reduce a large amount of fan power consumption by decreasing airflow and energy redundancy of the clean HVAC system, and can also serve as a guide for a proper design of air treatment and supply system in semiconductor cleanrooms.

What causes high energy consumption of a fan filter unit (FFU)?

The results indicate that the pressure drop of the make-up unit (MAU) system often exceeds 1000 Pa, and the cooling, heating and humidification coils account for 31.0%–41.9% of the resistance. Large airflow rates are the main factor that leads to high energy consumption of the fan filter unit (FFU) system.

How do you calculate fan power consumption in a cleanroom?

The fan power consumption (W, kW) of the cleanroom is determined as follows: (1a) W = Δ P f a n ⋅ G 3600 ⋅ η f a n where Δ P f a n is the total pressure rise of the fan (kPa); G is the volumetric airflow rate (m 3 /h) and η f a n is the fan efficiency (dimensionless).

Are fans energy efficient?

Energy Efficiency—Fan Operation the energy efficiency of fans. Fans are among the most significant single energy consumers and therefore represent an essential energy-saving area to reduce CO emissions. The lit- motors, of which about 15% is consumed by receivers driving fans. In the USA, fans op- drives [13,14].

Why do FFU systems consume a lot of energy?

Large recirculation airflow rates are the main factor that leads to the high energy consumption of the FFU system. On the other hand, the indoor cleanliness environment is often over-guaranteed, indicating the potential to reduce the supply airflow rate.
