Air Condition Systems which are installed in the home have a simple working pattern. Mainly air conditioners provide cold air inside the building or can heat the air in some closed spaces (heating mode).
How do AC systems work?
All these systems use a special chemical fluid which is called refrigerant. Moreover, each AC system has three main components:
- Condenser Coil
- Evaporator Coil
A compressor is a device that raises the gas pressure in the system by reducing its volume. Condenser and evaporator coils are the heat exchangers, parts of the system which are associated with heat transfer. They play an essential role in the refrigerant transfer process.
These components work together and change the phase of the refrigerant from gas to liquid and back again. The compressor raises the system pressure before the refrigerant enters the condenser coil, where it is converted to liquid. The phase change allows heat to be absorbed or released into the surrounding area. After, it is transferred to the evaporator coil. In this part, heat from enclosed spaces, such as rooms or offices, is absorbed by the refrigerant. The refrigerant then stores the heat, which can be easily transported. The heat is released to the outside when the refrigerant returns to its liquid phase. This process is usually called a refrigeration cycle. The air conditioning unit runs and repeats this cycle as long as it reaches the desired room temperature set on the thermostat.
