Why should air conditioners be installed at higher level?
Air conditioners are fitted at higher levels on the walls of a room in order to produce quick cooling in the room. This is because the cooled air from the AC comes down and the warm air from below rises up and a convection current is set up.
Which dB is best for AC?
So, if you’re looking for a quiet AC, make sure it’s within 50 to 60 dB.
What is the maximum degree of AC?
That’s because your air conditioner is designed to cool a maximum of 15-20 degrees from the temperature outside. Pretty simple math. If it’s 100 outside, and you’re not getting below 80 inside, your A/C is probably still doing it’s job.
Why does an air conditioning unit in a room have to be placed close to the ceiling?
Because cooler air falls, and warmer air rises. Inside the room, the A/C needs to be where it can gather the warm air, and where the cool air discharged can fall through the entire room instead of building up from the floor.
Why are the air conditioners placed near the ceiling?
The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. So it is placed near the ceiling so that the whole room cools down.
