For humidity removal a faster rate is not ideal.
Air conditioner humidity mode.
The drier air fills the room or area where the air conditioner is located.
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.
In this case the dry mode is useful.
Some benefits of aircon dry mode include.
Instead air passes through the device humidity condenses on the unit s evaporator and drier air exits the device.
Say your system moves air at around 400 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.
If the temperatures are low but the air is humid running an air conditioner in the cool mode will not be of much help.
Many systems are set up to move air at a rate faster than that.
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.
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.
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.
Greatly dehumidifying the room.
Your air conditioner will be effective at controlling humidity only if it is correctly sized for the amount of work it needs to do.
Running the air conditioner in dry mode helps as it removes the extra humidity in the air.
