Problem

  1. Jaya Marriage Hall is a convention hall for big wedding ceremonies, entertainment events, social events, formal meetings, and corporate gatherings.
  2. Since the hall is in the middle of the city, there was a problem of air movement therefore guests feels uncomfortable during summer season.
  3. The deep plan space of the hall need a large air circulation so that adequate fresh air would reach all occupants.

Solution

    • Epoch 2.0, 16-ft 03 Fans were installed with the following specifications ;
    • Motor: Epoch 2.0;
    • Coverage Area: 12,000 Sq. Ft. (1,114 Sq. m);
    • Speed: 95 RPM;
    • Peak Power: 1.1 kW/1.5 hp;
  • Epoch 2.0, 16 ft diameter five-bladed fan is cost effective and provide massive air movement.

Site Survey

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

  • Total Area: 250 Ft X 85 Ft = 21,250‬ Sq. Ft.
  • Floor to Ceiling Distance: 24 to 27 ft,
  • By a rule of thumb distance/1.5 gives us the approximate fan diameter.
  • In this case, we chose to go with a 16-ft fan.

Test Reports

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

Power Consumption Report

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 55, 65, 75, 85, and 95 RPM. Power drawn at those speeds are 440, 590, 710, 860, and 980 W 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.

Input Current Report

The input current is also measured at 55, 65, 75, 85, and 95 RPM. Input current is recorded as 1.9, 2.6, 3.0, 3.9, and 4.7 A respectively. The input voltage varied from 230 to 240V during the measurement.

Air Flow Report.

The airflow is measured from the center of the fan and is recorded at every 3-ft distance. Values were recorded upto 36-ft from the center of the fan. The values were respectively, 310, 344, 394, 551, 531, 511, 492, 472, 413, 351, 320, and 260 ft/min at distances of 3,6,9,12,15,18,21, 24, 27, 30, 33, and 36-ft respectively.
