Republicans on the House Small Business Committee pressed Energy Secretary Jennifer Granholm on Thursday for answers on proposed energy-efficiency standards for ceiling fans.

 

The proposed standards were first published in the Federal Register in June, and the comment period closed earlier this week. According to the Energy Department, the rule as applied to standard residential ceiling fans would cut fan-related electricity costs by about 40 percent relative to the least efficient fans currently available.

Here in Thailand I would recommend Mr Ken Fans as they have DC motors which are more energy efficient than AC motor fans

Always wondered....which way should they rotate?.....in a hot climate do they try to draw lower, cooler air upwards???

Some have a switch on the top to change the direction.

And so the great debate of 2023 begins. 

The question is are you trying to cool the room incrementally. ot yourself substantially? 

If you are drawing the lower cool air up the best you can achieve would be ambient temperatures. 

But if you are blowing the air on you , through skin evaporation you cool down substantially/

Bard AI Says:-

 

Summer:

During the summer, ceiling fans should rotate counterclockwise. This creates a downdraft that pushes cooler air down to the floor, where people are most likely to be. The wind chill effect created by the downdraft can make you feel up to 4 degrees Fahrenheit cooler.

Winter:

During the winter, ceiling fans should rotate clockwise. This creates an updraft that draws cooler air from the floor up towards the ceiling. This helps to distribute the warm air that tends to accumulate near the ceiling more evenly throughout the room. This can help you to feel warmer and reduce your heating costs.

Tips:

• In the summer, run your ceiling fan at a higher speed to create a stronger downdraft.
• In the winter, run your ceiling fan at a lower speed to create a gentler updraft.
• If you have a high ceiling, you may want to run your ceiling fan at a higher speed in both the summer and winter to help circulate the air more effectively.
• Many ceiling fans have a reverse switch that allows you to easily change the direction of rotation.

Exceptions:

There are a few exceptions to the general rule of thumb for ceiling fan direction. For example, if you have a fireplace, you may want to run your ceiling fan clockwise in the winter to help draw smoke up the chimney. Additionally, if you have a cathedral ceiling, you may want to run your ceiling fan counterclockwise in the summer to help circulate the cooler air that is trapped at the top of the room.

Overall, the best way to determine the best direction for your ceiling fan is to experiment and see what works best for you and your home.

So I conducted an experiment. 

I stood in front of the fan . Ahhhhh

then I stood behind the fan . sad but no joy. 

Conclusion. standing in front of the fan with a cold Leo in your hand  is preferable to cutting the grass in the hot sun. 😎

Just finished a Contractor meeting (moan), a cold Leo, even with no fan, sounds very inviting 🙂
