Modern air conditioner may not only cool the air in the room. It also has a lot of features, so this is multifunctional device, but not a simple household appliance that can only cool air. In particular, we are now talking about the functions such as Heat and Dry.
What does the dry mode on an air conditioner do?
Dry mode assumes dehumidification in the room. While this mode is ON, condensation of water occurs on the heat exchanger. It leads to a decrease in air humidity. If you feel more moisture in the room, then activate this mode. The air conditioner will draw moist air, remove moisture from it and transform to a condensate. Then, excessive moisture discharged through the water discharge pipe.
Dry mode is similar to a Cool mode, but there are differences. First of all in dry mode the fan of the indoor unit rotates more slowly. Does dry mode use less electricity? Hard to tell, but during dry mode the temperature in the room doesn’t change due to compressor is off. So power consumption is lower. Compressor will turn-on only if temperature in the room will be changed and then electricity usage will be standard of higher.
Heat function in AC unit
This function is appropriate when the room is cold. Turning-on Heat, the user activates the work mode for heating and if the room temperature falls below a user has defined, the air conditioner starts to heat the air. But there is one important point: in the specifications always written a parameter of minimum air temperature on the street at which user is able to turn-on the device.
Most models can work until the temperature outdoor is -5 C, and if the device will be activated at a temperature of -10 C, for example, there is a great probability of its failure.
