If the temperatures are low but the air is humid running an air conditioner in the cool mode will not be of much help.
Air conditioner humidity mode.
Instead air passes through the device humidity condenses on the unit s evaporator and drier air exits the device.
The fan runs at low speed and compressor is on for short duration in large cycles just to remove extra humidity.
Some benefits of aircon dry mode include.
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.
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.
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.
For humidity removal a faster rate is not ideal.
Dry mode doesn t really cool the room and the cooling effect comes from the removal of excess moisture from the 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.
In this case the dry mode is useful.
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.
The drier air fills the room or area where the air conditioner is located.
In hot humid climates like ours you want your air conditioner to move air at a rate at or near 350 cfm per ton.
