If you are planning to install air conditioning at your place, then you need to know some important things before installing an air conditioner. Air conditioner is a device which is used for cooling the room properly. It consists of a compressor, an evaporator and a condenser (the latter two equipped with a fan). The air from the room cools on the evaporator, giving off heat to the intermediate refrigerant that circulates in a closed circuit. The intermediate medium (gas) is then compressed in the compressor (its temperature increases) and is forced into a condenser which is outside (in the outside air). In the condenser, the heat from the refrigerant is transferred to the outside air, the gas condenses and becomes liquid (still under high pressure). Air conditioners require regular maintenance from time to time to protect the life of ac unit and keep it safe from getting its filters dirty because dirty filters can kill airflow and efficiency. You should keep the condenser and compressor clean and clear for its effective operation.

Types of Air Conditioners:
Based on the type of assembly, air conditioning machines can be of following types:
- Wall: This are installed into the wall and have a single unit.
- Under-ceiling or floor-standing: These are standing variants and the house walls do not need to be penetrated.
- Coffered: These are established in coffered ceilings.
- Duct: This is a centralized system of air conditioning.
Based on the number of indoor units connected to one outdoor unit, air conditioners can be of following types:
- Single
- Multiple
- VRV systems.
Based on the work mode, there are the following types:
- Air conditioners only with the cooling option
- Heating and cooling air conditioners (operating simultaneously as a heat pump or having an electric heater).
Based on the method of control and construction of subassemblies, there are two types:
- Classical air conditioners (with an ordinary compressor - constant speed, always 100%): The classic switches on when the room temperature exceeds the set level and turn off when it reaches the set value. This solution causes higher temperature fluctuations in the room and higher operating costs (high compressor starting current).
- Inverter air conditioners (seamlessly adjustable compressor speed): Inverters are more expensive but more energy-efficient. They smoothly adjust their efficiency and operation to room temperature, thanks to which they turn on and off less frequently. Switching on is carried out smoothly, without a "current" blow, so it does not generate unnecessary energy losses. Inverters also keep the set room temperature more precisely.

Types of Refrigerants in Air Conditioning Machines:
The refrigerant in the air conditioners is a quick-boiling substance, commonly called, albeit incorrectly, Freon. The most popular Freon in old-type air conditioners was R-22, which is currently forbidden to use due to its harmfulness. Nowadays, pro-ecological gases are used, e.g.: R-407C, R-410A, R-134A.
Functions of air conditioners:
The functions of an air conditioner are as follows:
- Change in air temperature (heating or cooling),
- Change of humidity (moistening or drying),
- Removing air components (filtering or replacing),
- Change of the local air speed.
Smaller air conditioning systems often do not master all these functions; but usually only spoken by an air conditioner, if at least the cooling function is present.
It can be understood that an air conditioning system is an air processing and ventilation system that generates and maintains a pleasant or required indoor air quality (temperature, humidity, purity and CO 2 content) independent of weather, waste heat and human and technical emissions. An air conditioner system has the task to bring the air of a room in a specific state and to hold ("conditioning"). Often, however, an air conditioner is understood to mean only room air cooling.
