Industrial cooling is a different setup than a household air-conditioning system. Both are used to control indoor temperature. But, there is a slight difference in their mode of operations and applications.
A heating, ventilation, and air conditioning (HVAC) system differs from an industrial chiller. It maintains the indoor air quality and temperature for comfort. On the other hand, an industrial chiller maintains the temperature of an industrial premise.
So, is a chiller considered an HVAC? How are they different?
Let us answer these questions with a concise table of differences.
Difference between HVAC and Process Chiller
| Aspect | HVAC Chiller | Process Chiller |
| Purpose | Primarily used for cooling air in buildings to maintain comfort. | Designed for cooling industrial processes or machinery in factories. |
| Application | Commercial spaces, offices, and homes. | Used in industrial units |
| Temperature Control | Focuses on general temperature and humidity control for human comfort. | Offers precise control over temperatures to maintain product quality and efficiency in machinery. |
| Durability | Built for moderate environments, with less exposure to harsh conditions. | Engineered for tough industrial settings, handling high demands and harsh conditions. |
| Energy Efficiency | Prioritizes cooling for human comfort, which may vary in energy consumption. | Optimized for process efficiency leading to reduced energy costs. |
| Design | Tailored for general cooling and air quality control. |
|
| Cooling Method | Cools air for occupant comfort. | Cools liquids or processes to maintain precise operational conditions. |
This table clearly explains how an industrial chiller differs from an HVAC unit. Both HVAC and industrial chillers are large-scale cooling systems. But, their applications are different. Let’s find out.
Where Should You Use Process Chillers: Areas of Application
As mentioned, process chillers are ideal for industries that need precise temperature control. Here is the list of industries where you can find process chillers used for precise temperature control.
- Manufacturing: Improve production quality and prevent overheating.
- Food and Beverage: Cools ingredients and products to ensure freshness and safety.
- Pharmaceuticals: Maintains stable conditions for sensitive materials during production.
- Plastics Industry: Regulates the temperature of molds and processes to prevent material defects.
- Chemical Processing: Provides stable cooling for operations and operators.
- Semiconductor Industry: Provides a stable environment for producing sensitive electronic components.
A small fluctuation in temperature may ruin operational outcomes for these industries. So, process chillers work stably round-the-clock to avoid operational inconsistencies.
What is HVAC More Fit for: Areas of Application
HVAC systems, on the other hand, are designed for:
- Commercial Buildings: Provides comfortable indoor climates for offices, retail spaces, and public areas.
- Residential Spaces: Regulates temperature and humidity in homes for comfort throughout the year.
- Hospitals: Ensures a stable and clean environment for patient care and infection control.
- Schools: Maintains a comfortable learning environment in classrooms and administrative areas.
- Hotels: Controls climate and air quality in guest rooms and common areas for a pleasant stay.
- Data Centers: Keeps critical IT equipment cool and prevents overheating to ensure reliable operations.
So, HVAC systems are designed to enjoy a relaxing limit for temperature control. They do not have to be as precise as process chillers.
Why Is a Chiller Better Than HVAC in Industrial Processes?
Chillers are often preferred over HVAC systems in industrial settings due to their specialized cooling capabilities:
Precision Temperature Control
Chillers provide exact temperature regulation for industrial processes. It is crucial for maintaining product quality and machinery performance.
Efficient Process Cooling
Chillers handle the high thermal loads typical in industrial operations. They ensure efficient heat removal from equipment and processes.
Robust Design
Industrial chillers are built to endure harsh environments and continuous operation. They offer durability and reliability where HVAC systems might fall short.
Separate Cooling Circuits
Many chillers feature independent refrigeration and water circuits. Such designs allow continued operation even if one circuit fails. HVAC systems often use a single combined-cooling unit which can be less reliable.
Higher Capacity
Chillers can handle larger cooling loads compared to HVAC systems. This capacity is essential for industries where significant heat is generated.
Energy Efficiency
Chillers are engineered for energy efficiency in high-demand situations. Their use often results in lower operational costs over time compared to HVAC systems.
On these grounds, process chillers are better in terms of energy and precise temperature control than HVAC systems. All you need to do is to choose the right chiller for your industrial unit.
