For example a window unit that s designed for a small room such as a home office will not function properly in a large master bedroom or great room.
Air conditioner humidity mode.
If the temperatures are low but the air is humid running an air conditioner in the cool mode will not be of much help.
The fan operates at a low speed while the compressor runs for shorter periods of time to ensure that humidity from the air is completely removed.
The drier air fills the room or area where the air conditioner is located.
Cool mode is the regular mode of most air conditioners and does not decrease the humidity in the air but the temperature of the room.
Instead air passes through the device humidity condenses on the unit s evaporator and drier air exits the device.
Many systems are set up to move air at a rate faster than that.
Some benefits of aircon dry mode include.
Say your system moves air at around 400 cfm per ton.
When your air conditioner is in dry mode the device s fan and inner components are running but the unit is not blowing out cold air.
Your air conditioner will be effective at controlling humidity only if it is correctly sized for the amount of work it needs to do.
In hot humid climates like ours you want your air conditioner to move air at a rate at or near 350 cfm per ton.
Dry mode doesn t really cool the room and the cooling effect comes from the removal of excess moisture from the air.
Running the air conditioner in dry mode helps as it removes the extra humidity in the air.
This surely is an electricity saving option during high humidity days as even the fan motor is running at a slow speed and even the compressor.
For humidity removal a faster rate is not ideal.
