Cooling requirements are widespread in both commercial and industrial sectors, and cooling is generally categorized in two ways: process cooling and comfort cooling or climate control.
Process Cooling vs. Comfort Cooling/Climate Control
Process cooling is applied when a process requires accurate and constant temperature control. Often in these applications, chillers are used to remove heat due to their ability to provide cooling capacity even through changes in ambient temperature, flow requirements, and heat load of the application.
Comfort cooling or climate control, on the other hand, regulates temperature and humidity in a space, and is generally simple, used for cooling rooms, electrical cabinets, and other spaces in which temperature does not have to be constant or precise. Air conditioning units fit into this category.
What is process cooling?
Process cooling, in its simplest form, can be described as the removal of unwanted heat from a process. This is often necessary to ensure the safety and efficiency of said process.
Why process cooling?
In many industrial processes, heat load is a component that must be carefully controlled. Furthermore, different aspects of the application might require cooling.
Key cooling areas include:
Direct cooling of a product
Plastic during the moulding process
Metal products during machining processes
Cooling of a specific process
Fermentation of beer and lager
Chemical reaction vessels
Hydraulic circuit and gearbox cooling
Welding and laser cutting machines
Within many processes, the integrity of the process itself as well as the final product is incumbent on the precision of heat management.
The key facets for a cooling requirement are to:
Improve the efficiency of a process
Enhance overall quality of finished product
Prevent spoilage of product by overheating
Increase production speed
Reduce wear and tear on machinery thereby reducing maintenance costs
Increase safety of process
Why use chillers for process cooling?
Process chillers, like Parker¿¿¿s line of¿¿production process chillers, can be integrated easily into most applications. It uses a refrigeration circuit to remove heat load passed onto the cooling fluid that returns from the application.
Process chillers are ideal for efficient cooling due to their ability to operate across a range of ambient conditions at variable loads. Advantages of utilizing process chillers include:
Constant, precise control of the process temperature
Can deliver cooling fluid directly to the application¿¿¿s heat source
Works independently of ambient conditions
Closed-loop water circuit minimizes potential contamination of the process
Recirculation of cooling fluid reduces costs and resulting waste
Modular design leaves room for expansion opportunities
High heat exchange capacity
Water is a low-cost, readily available resource within most industries
Potential to integrate into existing cooling systems
