Air conditioning systems work by removing hot air from inside a room and releasing cooler air to lower the temperature. This process follows the same principle used in standard refrigerators.

The entire process can be broken down into five steps: warm air is drawn by the air conditioner, cooled down by a cold evaporator, a dehumidifier removes excess moisture, a coolant absorbs the heat from the air and evaporates, and finally, the cool air is pumped back into the rooms.

Guests can vary the temperature of their rooms depending on personal preferences, thanks to intelligent systems in most air conditioners used in hotels.

Air conditioning works by removing hot air from inside a room and releasing cooler air to lower the temperature. This process is similar to how standard refrigerators keep the chamber cool.

The entire process can be broken down into five steps: warm air is drawn by the air conditioner, cooled down by a cold evaporator, and then pushed back into the rooms.

A key component of air conditioning is the coolant, which runs through chill pipes and absorbs heat from the air, causing it to evaporate.

As the warm air loses heat and cools down, it is pushed from the chill pipes, ready to be recirculated back to the rooms. The coolant is condensed back into a liquid by a compressor.

The cool or cold air is then pumped back into the rooms, helping to push down the ambient temperatures.
