Performance Testing (Physicochemical Scores)

This includes following Tests: Air Delivery | Service Value | Power Input | Starting and Running | Speed | Power Factor

Air Delivery 13.85

Air delivery essentially defines the amount of air a fan delivers – a crucial parameter since it translates into how comfortable you feel sitting under a running fan. As per Indian Standards, the air delivery of a 1,200 mm ceiling fan should be a minimum 200 m3/ min; however, for a BEE star-rated fan, air delivery should not be less than 210 m3/min.

Power Input 11.37

The power input defines the energy consumption of a fan. Maximum power input for fans of 1,200 mm size shall be 50 watts as per Indian Standards.

Service Value 12.9

‘Service value’ denotes the air delivery in metre cube/min, divided by electrical power input to the fan in watts (W) at test voltage and at full speed. In simpler terms, service value means the amount of air delivered per minute per wattage of electricity. As per Indian Standards, the service value of 1,200 mm fans should be a minimum 4.0 m3/min/W.

Starting and Running 5

The fan shall be capable of starting from rest when 85 per cent of test voltage or lower limit of voltage range is applied with regulator at lowest speed step.

Speed 3.24

Fan speed shall not exceed +_ 10% of marked value.

Power Factor 2.98

In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power factor can get values in the range of 0 to 1. It shall not be less than 0.90 for ceiling fans.
