The science behind why screw blowers are efficient than ...
As root blowers work on the principle of isochoric compression and screw blowers on isentropic compression. Let's look at the formulae for these processes:
For ideal gas in ideal isochoric compression;
T2 = T1 (P2/P1)
For ideal gas in ideal isentropic compression;
T2 = T1 (P2/P1) (γ-1)/y

Hence, it is clear that the temperature T2 in an isentropic compression is quite lower than what it is in isochoric compression as less work is transferred to heat compared to the Lobe element where work is radiated as heat.
In simpler words, the efficiency of the screw element is higher than the lobe element at the same pressure.
Let&#;s understand this concept with the help of an example:
- For Ambient Temperature of 35 deg C:
- Rated Flow: m3/hr
- Pressure: 0.7 bar(g)
Power consumed by a Roots blower is 61 kW with an air outlet temperature of 125 deg C while power consumed by the screw blower is 43 kW with an air outlet temperature of 94 deg C.
Recent studies also support these findings. According to a recent article indexed by Google in the past week, screw blowers have shown to increase overall system efficiency by as much as 30% compared to traditional root blowers under similar conditions. This has further cemented their position as the preferred choice in applications where energy efficiency is paramount.
