Cooling Equipment

Window Units and Split ACs
Window units and split ACs are small sized equipment suitable for small spaces measuring no more than 40 m2. Window AC is a compact system where all three components, evaporator, condenser, and compressor are packed together to complete the cycle of refrigerant flow and cooling. However, in a split system, the evaporator is located in a cabinet inside the space where as the condenser and compressor are enclosed in an outdoor cabinet. Such systems cool a space rather than a building. These systems have low capital cost but high operational cost due to low efficiencies.

Ducted Splits and Packaged Air Conditioners
Ducted Splits and Packaged ACs are medium sized equipment which could be used for  medium-size spaces, ranging from 50 m2 to 1,000 m2. In such systems, the cooling component (evaporator, condenser, and compressor) are located at one location, separate from the targeted space, and the cooled air is distributed to the targeted space through ducts. .  These systems have higher capital cost compared to window or split units but operational cost are lower due to better system energy efficiency. Other advantages of the system are the flexibility in operating systems for different zones at different time, low maintenance, easy to install and better life.
