How the cooling system of the air conditioner is built?

It is common knowledge that air conditioners generate cool air, and this very process is explained below.

 

All air conditioners are fitted with a built-in refrigeration system. This system is responsible for collecting energy from rooms and discharging it outside. This happens in the course of two processes: evaporation (the process of taking energy from the air in the room) and condensation (the process of discharging energy to the air outside). That is why this type of air conditioning is referred to as direct evaporation. To ensure that the cooling process always functions at low temperatures and the condensation process at high temperatures, variable pressure is generated in the refrigeration system: low pressure in the evaporator (at low pressure liquids evaporate at lower temperatures) and high pressure in the condenser (at high pressure gases liquefy at higher temperatures). This difference in pressure is generated by a compressor located between the evaporator and condenser. The last element of the refrigeration system is the expansion valve which maintains the generated pressure difference.

How the cooling system of the air conditioner is built?

Qo – energy taken from the room (cooling)

To- evaporation temperature (low)

Po- evaporation pressure (low)

Qk - energy transmitted to the environment (heating)

Tk- condensation temperature (high)

Pk- condensation pressure (high)

Pel- electrical energy driving the compressor

 

In order to intensify the energy transfer process, both the indoor and outdoor units of the air conditioner are equipped with fans, thanks to which the units are compact in size, while the energy and air in the room are intensively circulated.
