Feel refreshed without cold drafts

An air conditioner works by extracting heat from the indoors and releasing it outside. This is done via a refrigerant inside the air conditioning system and works in 3 steps: Step 1: the refrigerant inside the system evaporates (turns to gas) and in doing so absorbs heat from the inside air. Step 2: via a compressor the evaporated refrigerant is pushed through the air conditioning system to again become a liquid. Whilst the refrigerant turns back into a liquid, warm air is expelled via the outdoor unit Step 3: whilst the evaporated refrigerant is flowing through the air conditioning system, cooled air is circulated back into the room, providing a cooling effect to create a comfortable temperature indoors.
