Air conditioners with heating function are presented in a wide variety of price categories. The ability to use not only in the heat, but also during the off-season makes such models very popular and attractive to the user.
Heating function for air conditioners
- electric heater;
- Heat pump.
Electric heaters are more energy intensive. But heated air conditioners of this design are cheaper. With the help of fans, the air stream is driven through the heating element and supplied to the room.
The heat pump is the best modern development in the field of creating warm air conditioners.
The principle of its operation is based on the ability to remove heat from the atmosphere, transferring it to the air in the room. Even when it's freezing outside, the pump is able to extract heat.
For clarity, we will give an example of the operation of an air conditioner for heat. If you moisten the skin with alcohol, the body becomes cold. This means that the alcohol evaporates and draws heat away from the skin. Now let's imagine that the alcohol does not evaporate, but the heat taken from the body is accumulated. Nature has not created a single organism that uses this principle. But it was successfully implemented by the creators of heated air conditioners. The liquid refrigerant is sent to the outdoor unit, where it is forced to boil using special technologies, taking heat away from the air.
An economical system allows, spending 250 watts, to receive at least 1 kilowatt of thermal energy.
Characteristics of air conditioners operating on heat
Air conditioners with a heating function have a wide variety of characteristics:
- cooling capacity 2 - 10 kilowatts;
- heating power 2.8 - 11 kilowatts;
- in heating mode, air conditioners consume 0.8 - 3 kilowatts;
- service area 20 - 110 sq. meters;
- types of compressors: inverter and non-inverter;
- the presence of filters for coarse and fine cleaning, air ionization;
- the noise level of the indoor unit is 26 - 40 decibels;
- the noise level of the outdoor unit is 45 - 55 decibels;
- the maximum length of the cold line is up to 15 meters.
In heating mode, air conditioners operate up to -8 degrees (reversible, without winter package) or up to -20 degrees (inverter with winter package).
The best models of air conditioners with warm air operate with a power factor of 98%, which is close to ideal and is achieved through a special modulation of the electric motor.
