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…

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,…

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…

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….

How do you know Superfan saves energy?

How do you know Superfan saves energy?

Government of India through the Ministry of Power operates an agency called Bureau of Energy Efficiency (BEE) that assigns energy efficiency rating to appliances that are participating.  The efficiency is rated in a star-based system, with ‘5 stars’ indicating the most efficient and ‘1 star’ the least efficient. BEE formulates an efficiency parameter and its required value for each appliance. Many of us are familiar with the star rating in ACs & refrigerators. Recently, it was ruled that from Jan…

Consumer Asks 1: Brand distinction

Consumer Asks 1: Brand distinction

This is blog is based on a comment from one of our older blog, How to differentiate between true manufacturers and marketers in the ceiling fan industry? What’s the difference between 28W & 35W ceiling fans? Does the lesser wattage mean more energy efficiency? How natural breeze mode in Super A1 work?  The distinctions between brands are not just manufacturing and marketing, there is an addition – designers, manufacturers, marketers. Designers – Develop their own technology (Own the technology). Manufacturers…
