- Condensation the refrigerant in the state of very hot and compressed vapor then passes into a condenser (or heat exchanger), where it will give up heat to the external environment, which will allow it to liquefy, c 'that is to say to pass from the gaseous state to the liquid state;
- the now cold and partially vaporized refrigerant fluid circulates in an evaporator (heat exchanger) which is located in the part to be cooled. It subtracts heat from the medium (air) to cool it. By absorbing heat, the fluid refrigerant evaporates completely and changes from liquid to gas. The refrigerant is then ready to renew a new cycle.
- heat exchanger heat exchanger
