An air-cooled unit relies on fans to dissipate heat, while a water-cooled unit uses water for heat dissipation. Air-cooled units are compact, do not require a dedicated machine room, and are easy to maintain. However, their cooling and heating performance is greatly affected by the climate, and their energy efficiency is slightly lower than that of water-cooled units. Water-cooled chillers generally require a dedicated machine room along with a cooling tower; the system is somewhat more complex and its maintenance is more labor-intensive. Most of them cannot generate heat, but their advantage is that their cost is lower than that of air-cooled chillers, and their energy efficiency is slightly higher than that of air-cooled chillers.
Air-cooled units use fans to blow air or draw in air for cooling (the condenser), while water-cooled units utilize circulating cooling water to cool (the condenser).

An air-cooled unit achieves cooling by utilizing the refrigeration cycle of a chiller to cool water; since it relies on fans to exchange heat with the air, it also uses components such as fans and dust filters for heat dissipation. Air-cooled units can maintain a stable temperature, have reliable performance, take up little space, are easy to move, and are simple to operate. A water chiller cools the circulating water through its refrigeration system, and then delivers it to the equipment via a water pump and cooling water circuits. Chilled water units are less affected by environmental conditions, but they require a high-quality water source for circulating cooling. Due to the presence of cooling towers, water-cooled chillers take up more space and involve more work in terms of installation and maintenance.
An air-cooled unit means that the main unit is cooled by fans, while a water-cooled unit has the main unit cooled by water. Air-cooled units are compact, do not require a dedicated machine room, and are easy to maintain. However, their cooling and heating performance is greatly affected by the climate, and their energy efficiency is slightly lower than that of water-cooled units. Water chillers generally require a dedicated machine room, along with a cooling tower.
Air-cooled units use fans to blow air or draw in air for cooling (the condenser), while water-cooled units utilize circulating cooling water to cool (the condenser).
Air-cooled chillers are installed outdoors; they come equipped with their own fans and air-cooled condensers, and cooling is achieved directly through air. The water-cooled chiller is installed indoors; the condenser of the unit is fed with cooling water, which is then sent to a cooling tower for further cooling. Both air-cooled chillers and water-cooled chillers have a chilled water system, which utilizes chilled water circulation for cooling. Advantages of air cooling: it eliminates the hassle of cooling water treatment and is easy to manage. The downside is that its energy efficiency is relatively low. Advantages of water cooling: high energy efficiency. Disadvantages: The cooling water system generally requires water treatment and needs to be managed by a dedicated person.
