United Rentals is a top supplier of air-cooled chillers for rent. These chillers are a type of industrial cooling system that cool fluids by extracting heat from the air. As a result, the equipment cools and doesn't overheat, reducing the risk of malfunctions or fires. There are many different sizes and types of air-cooled chillers. The cooling air chillers are typically installed in factories, warehouses and other large buildings or any other environment where a lot of cooling is needed, so it is important to choose the right one for your needs. Cooling air chillers range from 10 tons up to 500 tons, are electric powered and come in mobile or static configurations. Several models are equipped with features to enhance efficiency, making them ideal choices for saving money and reducing negative environmental impact.
FAQs About Air-cooled Chillers
What is the difference between a water-cooled chiller and an air-cooled chiller?
In both types of chillers, an airstream circulates to transfer heat. However, water-cooled chillers utilize a humid air stream — a combination of natural air and sprayed water — while cooling air chillers utilize a current of ambient air — air in its natural state — for removal.
How does an air-cooled chiller work?
Air-cooled chillers comprise five main components: a compressor, a condenser, condenser fans, an expansion valve and an evaporator. As a portion of refrigerant moves through the chiller, it undergoes several transformations, starting at an elevated temperature and pressure level as a heated vapor and becoming a liquid when it enters the condenser. From that point, the refrigerant exits the condenser at an elevated rate of pressure but at a medium temperature as a saturated liquid, where it finally reaches the expansion valve, expands and becomes a liquid-vapor mixture. The mixture exits the expansion valve at a decreased rate of pressure and lower temperature and enters the evaporator where it flows through several tubes as “chilled water”. As the mixture leaves the evaporator it has picked up excess heat, dispersing it into the external environment.
Is one type of chiller more efficient than the other?
