Water cooled air conditioners are considered superior to air cooled air conditioners due to their ability to operate at lower condensing temperatures, thanks to the higher specific heat of water compared to air. This efficiency is particularly beneficial for capacity exceeding 20 tons, making them a popular choice for industrial and commercial applications.
Advantages of Water Cooled Air Conditioners
Efficient Cooling with Cooling Towers
One of the main advantages of water cooled air conditioners is their ability to recirculate water using a cooling tower, which reduces heat from the water to the air. This method is more efficient and environmentally friendly compared to disposing of the hot water into drains or ponds. The cooling tower can be built using corrosion-resistant materials such as copper, plastic, or stainless steel to ensure longevity.
Consistent and Efficient Cooling
Water cooled air conditioners are also beneficial in locations where drop ceilings or exhaust ducting are not available. They produce colder air more consistently and efficiently, using less energy than air cooled air conditioners. This makes them ideal for large buildings, facilities, and rooms with high ambient temperatures, such as server or computer rooms.
Smaller Size for Limited Spaces
Water cooled air conditioners tend to be smaller than air cooled air conditioners, making them more suitable for large spaces with limited space for air-cooled units. This can be particularly advantageous in commercial and industrial settings where space is at a premium.
Drawbacks of Water Cooled Air Conditioners
Constant Water Flow Requirement
One of the main drawbacks of water cooled air conditioners is that they require constant water flow to the unit, which can be a challenge in spaces without access to a water supply. This can be a significant limitation in areas with limited water resources or where the installation of a water supply line is not feasible.
Water Contamination and Maintenance
Another potential issue with water cooled air conditioners is that the water used in these systems can become contaminated with minerals and other impurities, which can lead to corrosion and other maintenance issues. Regular maintenance and cleaning of the water cooling system is essential to ensure optimal performance and longevity.

DIY Installation and Maintenance
Installing a water cooled air conditioner can be a complex process, and it is recommended to hire a professional HVAC technician to ensure proper installation and maintenance. However, there are some steps homeowners can take to prepare for installation:
- Identify a suitable location for the unit, with access to a water supply and a drain.
- Ensure that the area around the unit is clear and free of obstructions.
- Follow the manufacturer’s instructions for installation, including any required electrical or plumbing connections.
- Regularly maintain and clean the water cooling system to ensure optimal performance and longevity.
Conclusion
Water cooled air conditioners are a highly efficient and effective solution for cooling large spaces, particularly in industrial and commercial applications. However, they do require a water source and a drain, making them less suitable for spaces without access to a water supply. By understanding the advantages, drawbacks, and technical specifications of water cooled air conditioners, you can make an informed decision on whether they are the right choice for your cooling needs.
