A Case Study : Epoch HVLS 24-ft Fan By Falco eMotors Inc.
Report No. 040720-01

                                            

Problem:

1. In the summer, there is a problem with air movement in the warehouse shop sheds of the Hiveloop technology.

2. Summer temperatures make the warehouse environment hot and humid. Workers were unable to work in such environmental conditions.

3. Workers at Hivelop Technologies warehouse are disturbed by physical and mental comfort. Workers are upset because there is no movement of air in the warehouse.

4. In order to get the best output of the workers, the Hiveloop Officials decided to install the HVLS fans in the warehouse.

                                            

                                            

 

Solution:

• Epoch 3.0, 24-ft 05 Fans was installed with the following specifications ;
• Motor: Epoch 3.0;
• Coverage Area: 30000 Sq. Ft. (2787 Sq. m);
• Speed: 62 RPM;
• Peak Power: 1.5kW/2 hp;

• Epoch 3.0, 24 ft fans are most popular with amazing airflow and airflow efficiency.

                                            

Site Survey:

A site survey is mandatory before any HVLS fan recommendation. The survey revealed the following dimensions:

• Total Area: 501 ft X 167 ft = 83,667‬ Sq.ft.
• Floor to Ceiling Distance: 35 to 40 ft,
• By a rule of thumb distance/1.5 gives us the approximate fan diameter. 
• In this case, we chose to go with a 24-ft fan.

                                            

Fan and Coverage Area:

                      

Test Reports:

Three test reports are collected for each fan installation as follows:

1. Power Consumption Report;
2. Input Current Report;
3. Air Flow Report.

Those reports are shown for this site:

                                            

Power consumption report captures the real as well as apparent power. Epoch HVLS fans are the only fans in the world to have active power factor correction and unity power factor. Therefore the Watts (Real Power) and VARs (the apparent power) are almost the same. The power has been captured at 22, 32, 42, 52 and 62 RPM. Power drawn at those speeds are 118, 118, 389, 720, 1080W respectively. The chart above also shows trend lines generated using Excel for real and apparent power to take into account any measurement errors as fan power consumption can be modeled by well known equations.

                                             

The input current is also measured at 22, 32, 42, 52 and 62 RPM. Input current is recorded as 0.57, 0.92, 1.8, 3.1, and 5.09A respectively. The input voltage varied from 230 to 240V during the measurement. 

                                            

The airflow is measured from the center of the fan and is recorded at every 3-ft distance. Values were recorded upto 30-ft from the center of the fan. The values were respectively, 180, 220, 339, 460, 494, 417, 450, 390, 330, 310 ft/min at distances of 3,6,9,12,15,18,21,24,27 and 30-ft respectively.

 

Estimated Yearly Savings while Using Epoch HVLS Fans

                                            

Epoch 24-ft fan was compared against Indian HVLS fan Manufacturer. Based on their data sheet, daily, monthly and yearly power consumption and costs were calculated. An Epoch HVLS fan will save the end user anywhere from $2,393 to $10,932 per year over any competitive brands because of its unique technology.
