The video explains how air conditioners work by cooling entire rooms using a cycle of compression and expansion of a working fluid. It details the main components: compressor, condenser, and evaporator, and describes their roles in the cooling process. The compressor increases the fluid's pressure and temperature, the condenser cools it down, and the evaporator facilitates heat exchange, ultimately cooling the air inside the house.

What happens to the working fluid as it moves from the condenser to the evaporator?

Explain the role of the evaporator in the air conditioning process.
