How Air Cooled Chillers Work - The Engineering Mindset

In this article we will be looking at how air cooled chillers work. Air cooled chillers are very common, especially in small to medium size commercial and office type buildings. They are usually located externally, either up on the roof or at ground level. This is because Air Cooled Chillers do not use cooling towers, instead they dump their heat into the ambient air and therefore need access to a lot of fresh air, in order to reject the unwanted heat from the building. Scroll to the bottom to watch the tutorial video on this subject.

Difference Between Air Cooled and Water Cooled Chiller System

Many regions in the world are grappling with water scarcity. Numerous efforts to desalinate and trade in water are evidence of the magnitude of the problem. The World Bank puts the number of people living with absolute water scarcity at 2bn, a number that could hit the 4.6bn mark within the next 65 years.

Chiller - Wikipedia

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes.[1]

The current design and operation of air-cooled condensers can cause a significant decrease in chiller performance under part load conditions. This paper demonstrates optimal condenser fan control to improve the coefficient of performance (COP) of air-cooled chillers. This control involves identifying the optimum set point of condensing temperature with the optimized power relationships of the compressors and condenser fans and enhancing the airflow and heat transfer area of the condensers. An example application of this control for an air-cooled centrifugal chiller indicated that the COP could increase by 11.4–237.2%, depending on the operating conditions. Such the increase of the COP results in a reduction of up to 14.1 kWh/m2, or 27.3% in the annual electricity consumption per unit A/C floor area of chillers, given that the chillers serve an office building requiring an annual cooling energy per unit A/C floor area of 173.3 kWh/m2. The simulation results of this study will give HVAC engineers a better understanding of how to optimize the design and operation of air-cooled chillers.
