Air-Cooled vs. Water-Cooled HVAC System Difference

07 December 2020

Heating, ventilation, and air conditioning (HVAC) systems can be beneficial to properties, especially on residential, commercial, and industrial buildings. They basically provide people with their needed comfort and suitable breathing conditions without obtaining any health issues as system components can improve the overall air quality, climate, and ventilation of involved spaces. These systems likewise improve the savings of property owners when it comes to energy bills and even maintenance costs.

Today, property owners can choose between air-cooled or water-cooled HVAC system. Both systems possess unique qualities and capabilities that can make them beneficial for select people. If you want to know more about them, here are some of their notable and distinctive features about these systems.

Air-Cooled HVAC System

Air-cooled HVAC systems solely rely on a current of ambient air in transferring heat and conducting other processes required for cooling a specific property. And since they do not rely heavily on water, these systems do not have to acquire cooling towers for the said supply. The lack of these components makes them more appealing for properties that possess minimal aesthetics or constrained space. Additionally, properties that have limited or restricted water supply can easily take advantage of these systems.

Aside from the aforementioned benefits, air-cooled HVAC systems can be advantageous for property owners since they can prevent a lot of unnecessary expenses. The maintenance costs of these systems are far lower than the others. They likewise avoid chemical costs and water costs. The overall operations of these systems are also much easier and quieter than the water-cooled HVAC systems.

Take note, however, that the installation costs of these systems can be expensive due to the inclusion of air ducts, fans, thermoregulation controls, and many more. They also need to have a lot of space since their components depend hugely on the presence of ambient air.

Water-Cooled HVAC System

Water-cooled HVAC systems, on the other hand, are comprised of condensers that are attached to cooling towers, allowing them to properly maximise water in providing the cooling temperatures of specific properties. Water-cooled HVAC systems rely heavily on the presence of water, which is why properties that have a constant supply of the said resource can take advantage of these systems. The expected expenses over these systems can go higher than air-cooled HVAC systems, but they are guaranteed to provide a much more stable supply of cool air since they do not rely on the ambient temperatures.

Apart from the cooling tower, other components that can be found on water-cooled HVAC systems are condenser water pumps, make-up water pumps, and chillers. All these components work together to make water-cooled HVAC systems become more efficient and last longer than their alternative. These systems are also cheaper to install compared to air-cooled HVAC systems.

One drawback, alternatively, of these systems is that they have constant expenses when it comes to the mandatory treatment of water and other components. Their operations can also cost a lot more expensive since they need to utilise constant water and energy supply.
