Air-conditioner is suitable for humid days

The air-conditioning drying mode does not directly cool but works with a moisture reduction mechanism thereby indirectly lowering the air temperature.

The cooling mode (snowflake symbol) blows out cold air to remain at the set temperature.

Cooling mode (Cool) is the main feature of the air conditioner but under certain conditions of use, the drying mode can also provide cooling efficiency and a number of advantages in energy saving, less make noise. Users should therefore understand the mechanism of action of both modes for proper use.

Cooling mode (Cool) uses condenser to cool the air passing continuously. For example, if the temperature is set at 26 degrees Celsius, the air conditioner always tends to cool until the room temperature reaches this threshold. Meanwhile, the drying mode (Dry) works towards maintaining a humidity of about 60% for the room.

When the air conditioner operates in the drying mode, the fan and internal components are still running. However, the indoor unit will not blow out cold air like in Cool mode. The air with water vapor in the room passing through the device will condense. Operating in this mode is similar to a dehumidifier. However, dehumidifiers operate more efficiently and have greater capacity, allowing the humidity threshold to be set to as low as about 30%.

The drying mode (water droplet symbol) condenses steam, reducing the humidity to make the air feel cooler.

Cooling in the dry mode (Dry) is only effective for the sky or in the wet season. Users feel that the air is cooler because the room's humidity is reduced instead of the actual cooling air as in the Cool mode. For example, when it is set to Dry mode at a temperature of 25 degrees C and the humidity in the room is about 90% high, the air conditioner will perform air drying until the temperature drops to about 25 degrees C and stops. When the humidity rises, the temperature rises again, the machine will continue to operate to maintain low humidity.

Due to the drying mode, the compressor only works to condense moisture, so the air conditioner makes less noise and consumes less electricity than the Cool mode. However, when the days are too hot or the humidity is low, the Dry mode does not provide a significant cooling effect. The abuse of this regime in hot and dry days even harms human health such as respiratory diseases, skin dryness, chapped limbs .

Users should have an additional humidity meter in the room.

To make sure whether or not to use Dry mode, users should have a room humidity meter. If the humidity is higher than 70%, this mode should be used, in the case of less than 60%, the air conditioner should be turned on in the normal cooling mode (Cool) in combination with using a humidifier or leaving a basin Small water in the room.

In Vietnam, users can use the Dry mode in the wet season in the North (February, March every year) or the rainy season in both regions. In the early winter in the North, some hot, humid days can also use this mode to make the atmosphere more comfortable.
