What determines ceiling fan airflow? [4 crucial parameters]

What determines ceiling fan airflow? [4 crucial parameters]

The primary use of ceiling fans is to offer the desired thermal comfort by delivering sufficient airflow. There is a misconception of relating airflow to only the speed of a fan (RPM). Though, it is true that when the speed (RPM) of a fan increases by 10%, the airflow increases by 10%. Explore fan laws.  But the speed of a fan is not the only parameter that influences the airflow, and it is wrong to compare two fans by their…

How can you use ceiling fans in winter?

How can you use ceiling fans in winter?

In a closed space like a room with still air, the cooler air stays at the bottom, and the warm air rises to the ceiling. This segmentation of air happens due to the difference in the densities, and this phenomenon is called stratification. This becomes a problem in winters as the much-needed warm air recedes to the ceiling leaving the space close to the floor cooler. When heating elements are used to warm the space, it requires more heat generation…

ECO-FRIENDLINESS IS A WAY OF LIFE AT SUPERFAN

ECO-FRIENDLINESS IS A WAY OF LIFE AT SUPERFAN

Many BLDC ceiling fans are marketed as eco-friendly, as they save about 1 kg of CO2 emissions and 2 liters of water every day by conserving electricity. While claiming eco-friendliness in advertisements, they seem to continue to use plastics in packaging, not utilizing ROHS electronic components, not avoiding processes that impact the environment. Their claim of eco-friendliness tends to be empty especially when those manufacturers began making BLDC ceiling fans because of the government mandates. Is postponing bee star rating…

CAN WE USE AC AND CEILING FAN TOGETHER?

CAN WE USE AC AND CEILING FAN TOGETHER?

Yes! Using AC and ceiling fan together is bound to give advantages to us in power savings and eco-friendliness. Air conditioning (AC) is currently the most effective method of cooling indoor space. However, its growing global use is problematic for a variety of reasons.   Typically, a 1-ton AC consumes more than 800 W per hour. Widespread use of air conditioning puts a strain on the electricity distribution system and raises the risk of power shortages.    Through heat ejection, air conditioning contributes to the Urban…

THERMAL ADAPTABILITY AND CEILING FANS

THERMAL ADAPTABILITY AND CEILING FANS

Thermal adaptation is the ability of the human body to adjust to temperatures. The human body works to maintain the core body temperature at 37° celsius. The loss or gain of heat from the environment activates the thermal regulators in the body to warm or cool respectively. The thermal regulation system in our body functions intending to keep ourselves at a comfortable temperature. The core of our body passes on heat to the skin to maintain comfort during cold climates,…

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…
