I live in Indonesia and I have an apartment with a 6.7 x 5m room, which contains a dining table and a couch. In this room are two 1.5PK (13,000 BTU) AC units on the same side of room nearer to the couch. If I turn on both ACs I think it's cool enough when I'm sitting on the couch because it's quite near the AC, but not at the dining table. I can barely feel any breeze at the dining table and so it's unpleasant sitting there. This is when only I am in the room. I can't imagine what it's like when I'm having guests.. I was suggested to install stronger ACs, but I fear that's gonna be costly and also it'll be freezing cold near the couch but so-so cold at the dining table.
I think the two AC units are cool enough, but perhaps the cool air is not circulating to all corners of the room. What is your suggestion to keep the whole room evenly cool?
Thank you very much
Best Answer
A common method of equalizing the temperature across a room is to add a ceiling fan.
Cool air tends to stay near the floor, and a fan can be set to pull the air upwards. As it hits the ceiling, the air is pushed outwards to the edges of the room. Because cool air is heavier than warm air, it then moves downward, better distributing the temperature.
A very low setting can be used to avoid noise and strong air currents. This is easier with fans that have variable speeds, which is common with remote control types.
This technique is also used to circulate warm air for heating systems that need help with temperature distribution.
SUPPLEMENT
The ceiling fan should be placed near the center of the room. Most fans are reversible. The fan should be set to blow upward, if possible.
Floor fans can also be used.
Similarly, a pedestal fan.
If using a floor or pedestal fan, place near the air conditioning flow and direct the fan upward and toward the other end of the room.
