An air-cooled scroll chiller isa refrigeration system that uses ambient air to reject heat, employing scroll compressors for efficient cooling and is commonly used in commercial and industrial applications.
Key Features and Functionality:
Air-cooled scroll chillers use the vapor compression refrigeration cycle, where a refrigerant is compressed, condensed, and then expanded to remove heat from a liquid, typically chilled water, which is then circulated to the cooling load.
The core of the system is the scroll compressor, which is a type of rotary compressor known for its reliability, efficiency, and ability to modulate capacity to match cooling demands.
Heat rejected from the refrigerant is dissipated into the ambient air through a condenser, which is typically a finned coil or radiator.
The evaporator is where the chilled water absorbs heat from the refrigerant, lowering the water temperature.
Air-cooled scroll chillers typically use environmentally friendly refrigerants like R-407C, R-410A, or R-134A.
Many models utilize multiple compressors with independent refrigerant circuits, allowing the system to adjust capacity based on cooling demand, maximizing energy efficiency.
These chillers are used in a wide range of applications, including air conditioning, process cooling, refrigeration, and cooling for industrial processes.
They are known for their efficiency, reliability, low noise levels, and compact design.
The design of the chillers with separate refrigeration circuits makes servicing and maintenance easier.
