WHAT IS THE EFFECTIVENESS OF A CEILING FAN?

WHAT IS THE EFFECTIVENESS OF A CEILING FAN?

The primary objective of a ceiling fan is to offer thermal comfort to the occupant. The effectiveness of a ceiling fan is the measure of its thermal comfort and its other aspects like efficiency, durability, noise limit, wellness, local influence, value, environmental impact.  Thermal comfort  The condition of people’s minds that expresses satisfaction with the thermal environment is called thermal comfort.    For many years, humans have been using fans to regulate thermal comfort. Ceiling fans regulate their occupants’ thermal comfort…

SUPERFAN AND BANNISTER EFFECT

SUPERFAN AND BANNISTER EFFECT

Bannister effect   For decades in the first half of the twentieth century, running a sub-4-minute mile was considered a barrier in athletics. Breaking the barrier, according to experts, required peak performance in ideal weather and track conditions.  Roger Bannister, a full-time student with no formal training, devised a strategy to break through the elusive barrier. He was considered an outsider and un-conventional. On May 6th, 1954, in a small meet at Oxford, England, attended by few thousand, he breached…

HOW TO INSTALL YOUR CEILING FAN SAFELY FOR BEST PERFORMANCE?

HOW TO INSTALL YOUR CEILING FAN SAFELY FOR BEST PERFORMANCE?

The installation location and space of a ceiling fan are as important as choosing the right ceiling fan. The appropriate location and space determine the effectiveness of the ceiling fan. The effectiveness of a ceiling fan is the required thermal comfort, efficiency, quietness. To get optimal effectiveness from a ceiling fan the following clearances must be taken into account: Mounting height – distance above the floor level to fan blades tip Side clearance – distance from the walls/obstructions to fan…

Can a BLDC ceiling fan consume 28W or lesser?

Can a BLDC ceiling fan consume 28W or lesser?

BLDC ceiling fans are marketed based only on their power consumption. But the power consumption depends on various other parameters, size, airflow, speed to name a few. Especially the ’28 W‘ is being used in the market a lot, is it true? Can a BLDC ceiling fan consume 28W or lesser? There could be two possibilities: 1. It could be a marketing gimmick of expressing the specification of the BLDC ceiling fan in a clever way to deceive. One step…

Superfan: FAIR FAN that offers FAIR FLOW

Superfan: FAIR FAN that offers FAIR FLOW

Is the ceiling fan you buy, fair to you and everybody else? Superfan makes ceiling fans that strive to be fair to the consumers, the nation, and the environment. CUSTOMERS Sensible Innovation Ceiling fans earlier were negligent about power consumption, contributing to expensive electricity bills and pollution due to electricity generation, Superfan broke this stereotype in 2012 by inventing India’s first super energy efficient ceiling fans. This innovation replaced the inefficient AC induction motor of ceiling fans with Brush-Less Direct…

FAN LAWS

FAN LAWS

Formulae 1 to 4 can be applied to any fan provided the diameter does not change. If the diameter does not change the fans must be geometrically similar. The units of density, fan rotational speed and diameter are not important as long as both are the same. In formulae 5 to 8 the units shown in the nomenclature must be used to satisfy the formulae Volume Flow Pressure Absorbed Power Sound Power Level Density Fan Total Efficiency % Fan Total…

High flow ceiling fans & High speed ceiling fans

High flow ceiling fans & High speed ceiling fans

How ceiling fans move air? A ceiling fan is a simple electrical appliance with blades mounted on a motor which rotates the blades to push the air and create airflow. The airflow from ceiling fans is measured in Cubic Meter Per Minute (CMM). The airflow has two components, the volume of air moved and the speed at which that volume of air moves. Fan designers vary the two components to make fans suitable for different applications with the same airflow….

Regulator BLDC ceiling fans

Regulator BLDC ceiling fans

The function of a regulator is to provide the user with control over the fan. This control comes with a loss of power. Therefore, it is good to choose the type of regulator that minimizes this loss (To know more read: What does a fan regulator do? ). Regulators also save energy as the user can operate the fan at the desired RPM, which may be lower than the highest RPM in many instances. Currently, capacitive-based regulators are the best…

What does a fan regulator do?

What does a fan regulator do?

Regulators, as the name suggests, regulate or control the speed of the fan motor. They have been around since the 1950s, and there are a few types of them. Resistive regulator   These are the box type regulators, found in many old building and homes. It has a wire wound resistor with different contact points as the speed positions, with each contact point corresponding to a resistance value. The presence of resistance reduces the voltage supplied to the fan. In an AC induction motor,…
