Product

Problem

  1. Samcon Industrial Controls Private Limited is a manufacturer & supplier of Electrical Control Panels required for HVAC, Engineering, Power Distribution and Process Industries.

  2. The climate in Asangaon is tropical. The tropical climate is characterized by its humidity, which reinforces the feeling of warmth. Hence cooling system is needed.

  3. These hot and humid working conditions, especially in the summer days, affects the health of workers but also reduce the productivity and quality of their work.

  4. There are floor-mounted fans in the spot cooling in a limited area of the factory. But the difficulty arises in their speed, noisy operating levels creates Stressful work environments, and they consume large amounts of electricity.

Solution

  • Epoch 2.0, 16-ft Fan 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: 90 Ft X 40 Ft = 3,600‬ 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 310, 530, 650, 840, 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 1.2, 2.1, 2.6, 3.9, and 4.4 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 30-ft from the center of the fan. The values were respectively, 270, 390, 420, 470, 540, 460, 410, 320, 260, and 240 ft/min at distances of 3,6,9,12,15,18,21, 24, 27, and 30-ft respectively.
