Chiller System Design Guide- a Recommendation from Expert. It contain many useful information for engineers and engineering students.
Please note that this document is for reference only and is not an actual design manual. In practice, construction and plumbing methods may vary according to the project requirements and local code. Hence, to complete design and installation of the system, please consult your local engineer.
An air-cooled chiller has a condenser that uses air for heat transfer. Air-cooled chillers are likely for small or medium installations but recently the quality improvement in their structure allows the use in modular setups for large installations as well. Moreover, we use an air-cooled chiller especially in cases where there is not enough water or the water is very expensive.
Water-cooled chillers have a water cooled condenser connected with a cooling tower. Thus, they are usually popular for medium and large installations where there is a sufficient amount of water. In addition, they are also better in cases where there is a demand for constant operation of the system, independently of the ambient temperature (industrial air conditioning, air conditioning of digital systems etc.). The capacity of the water-cooled chillers are less affected by the ambient temperature conditions.
