As an AI language model, I don't have access to specifics regarding the villa in question, however, below are some of the common types of cooling systems used in duplex villas:
1. Central air conditioning: This is a common cooling system used in duplex villas. It uses a network of ducts to distribute cool air throughout the house.
2. Split air conditioning: This type of cooling system consists of a unit that is installed outside the villa and one or more units installed inside the villa. The outdoor unit cools the refrigerant in the indoor units, which then blow cool air into the rooms.
3. Evaporative cooling: This type of cooling system is common in hot and dry climates. It uses evaporative cooling pads or rocks that cool the air passing through them.
4. Window air conditioning: This is a low-cost cooling system that is installed in a window. It is suitable for small villas and individual rooms.
5. Portable air conditioning: This type of cooling system is similar to window air conditioning but can be moved from room to room.
6. Geothermal cooling: This is a more energy-efficient cooling system that uses the constant temperature of the earth to cool the house.
