Chillers are Refrigerant systems that help in cooling machines, industrial processes, industrial operations, and industrial chemicals.
A chiller moves heat from one location (product) to another (outside environment) to chill using water or glycol solution using a pumping mechanism.
How do chillers work?
Chillers work through a vapor-compression or absorption refrigeration cycle. This cycle includes four components of a chiller.
Components of a chiller.
- An evaporator.
- A compressor.
- A condenser.
- A thermal expansion valve.
The evaporator moves heat from the water outside which gets chilled by the chiller components.
The condenser transfers heat once it has been passed through the refrigerant to cool the outside system. There are two types of condensers. Air-cooled and water-cooled condensers.
The thermal expansion valve regulates the flow and pressure of the refrigerant coolant.
The compressor pushes a refrigerant gas around the inside of the chiller through the condenser, the expansion valve, and the evaporator and back to the compressor.
The principle of vapor compression and vapor absorption
- A chiller works by providing a constant and continuous flow of coolant at the desired temperature. A coolant is then pumped through the system, therefore, extracting heat from the desired areas and returning through the return side of the system.
The refrigerant circulates through the condenser, compressor, evaporator, and thermal expansion valve where the thermodynamic process occurs.
Applications of Chillers.
Heat is a common byproduct of most industrial and chemical processes. It is important to removed the heat produced during these processes. This avoids inefficiencies that may arise due to the accumulation of heat over time. These inefficiencies include equipment malfunction, equipment failure, or equipment shutdown
The application of chillers include;
- Injection molding.
- Food and beverage.
- Laser chemicals.
Benefits of Chillers
Chillers provide consistent temperature and pressure or optimum performance of a machine.
Simplifies the process and development of high-quality end products.
What works for you?
Chillers vary in size and design depending on the application be it large or small scale. While choosing what cooling solution works for you, contact an HVAC specialist at HotArctic Heating and Cooling. The specialist will guide you through your options.
