How does an air-cooled chiller operate?

An air-cooled chiller operates by utilizing ambient air to cool the refrigerant that circulates through the system. This process eliminates the need for additional components like cooling towers, which are typically necessary in water-cooled systems. The chiller contains a condenser where the refrigerant is cooled as it passes through. Electric fans draw in surrounding air, which flows over the condenser coils. As the air moves across these coils, it dissipates heat from the refrigerant, lowering the refrigerant's temperature before it enters the evaporator section of the chiller.

This design allows the chiller to efficiently expel heat directly into the atmosphere, making it suitable for various commercial applications. In contrast to options that involve water systems or cooling towers, air-cooled chillers are often easier to install and require less maintenance due to their reliance on air for cooling rather than water resources.
