An Industrial Process Chiller is made up of several essential components that work together to regulate temperature and ensure smooth operation. Each part plays a crucial role in the refrigeration cycle:

1. Compressor:
   This is the heart of the chiller. It compresses the refrigerant gas, increasing its pressure and temperature so it can move through the system efficiently. Types of compressors include scroll, screw, reciprocating, and centrifugal, depending on the chiller’s capacity and design.
2. Evaporator:
   The evaporator is where the process fluid (such as water or glycol) passes through and loses its heat to the refrigerant. This is where heat absorption occurs, and the refrigerant turns into a gas.
3. Condenser:
   After compression, the hot refrigerant gas flows into the condenser. In this component, the heat is removed either by air (air-cooled) or water (water-cooled), and the refrigerant changes back into a liquid.
4. Expansion Valve:
   The expansion valve regulates the flow of refrigerant into the evaporator. It reduces the pressure and temperature of the liquid refrigerant before it re-enters the evaporator to absorb more heat.
5. Process Pump & Reservoir:
   A circulation pump pushes the cooled fluid to the process and brings the warmed fluid back to the chiller. The reservoir holds the process fluid and acts as a buffer to handle thermal loads.
6. Control System:
   Modern chillers come with advanced control panels and sensors that monitor and regulate temperatures, flow rates, pressures, and operating parameters for safety, efficiency, and precision.
   Together, these components form a reliable and energy-efficient system that keeps industrial operations stable, regardless of heat-generating activities within the facility.
