How Low-Temperature Chillers Work
Basic Functionality
A low temperature chiller cools by moving heat away. It uses a refrigeration cycle with four steps: evaporation, compression, condensation, and expansion. In evaporation, the refrigerant takes heat from the material, turning into gas. The compressor raises the gas's pressure and temperature. In the condenser, the refrigerant releases heat and becomes liquid again. The expansion valve lowers the pressure, so it can absorb heat again.
To work well, the system needs regular checks and adjustments. Changing settings on chillers, cooling towers, and pumps saves energy. Adjusting these parts helps keep temperatures steady and reduces power use. All parts must work together for the chiller to run smoothly.
Modern chillers are very efficient. Some have a Coefficient of Performance (COP) as high as 10.7. They can save 30–50% more energy than older systems. This makes them a great choice for industries needing reliable cooling.
Key Components of a Low Temperature Chiller
Knowing the main parts of a chiller helps you understand how it works. Each part has an important job:
Compressor: This part pushes the refrigerant, raising its pressure and heat.
Evaporator: It absorbs heat, turning the refrigerant from liquid to gas.
Condenser: It releases heat and turns the refrigerant back into liquid.
Expansion Valve: This lowers the refrigerant's pressure so it can cool again.
Control System: Modern systems let you adjust and monitor settings. They help keep temperatures accurate and save energy.
These parts work together for smooth cooling. For example, a chiller's Specific Cooling Effect (SCE) can reach 7793 kJ/kg. This shows it can handle tough industrial tasks. Choosing a chiller with good parts ensures it works well and lasts long.
