Know what air conditioner dry mode does?

As suggested by the title above, not everyone’s aware what the function of the dry mode is on an air conditioner. The ‘Dry’ mode has the symbol of a drop of water on the remote control as opposed to the normal ‘Cool’ mode which has a symbol shaped like a snow flake. Operating the air conditioner in dry mode could lead to saving on power bill and yet having the cool benefit at the same time.


Understanding dry mode, what exactly is dry mode?

Dry mode is often compared and confused with the cool mode. On the remote, the dry mode is shown by a symbol which is a water drop; on the other hand the cool mode symbol is frequently a snow flake. Main purpose of the dry mode is to reduce humidity. An increase in humidity translates into an increase in temperature. When it is humid, temperatures even those that are relatively low tend to be a bit too uncomfortable.

So, basically the dry function reduces the temperature in a room by lowering the humidity. This function is most convenient during those times of the year when it is humid for instance during the rainy season. During this season the temperatures might not be hot enough for the need for cold air. The humidity however, is high and quite irritating. One point worth noting is that the dry mode is not meant to remove all the moisture in the room.

Notice there is different types of mode


Working principle of dry mode

When the air conditioner is functioning in dry mode, the fan and other inner components of the device will be running. However, the unit does not blow out any cold air. The air in the room passes through the air conditioner and the water vapor condenses on the evaporator. Dry air will then exit the unit and flow back into the room.

Assuming that the thermostat is set to 25 degrees C and that the humidity in the room is about 90%, the air conditioner will reduce humidity till the temperature reaches 25 degrees C. When the air conditioner is switched on, the fan will start running to suck in the air and the compressor cuts in to facilitate the condensation of the humidity. Once the room temperature has dropped to 25 degrees C then both the fan and compressor will stop. Humidity rises steadily again and so does the temperature. When the temperature rises above 25 degrees C the unit starts running again and the cycle repeats itself.


Benefits of dry mode:

  • Energy saving
  • Maintaining comfortable temperatures without really cooling
  • Lowering moisture in the room significantly thus lowering temperature
