What are the advantages and disadvantages of a chilled water system?


  • Longer Lifespan. Water-cooled chillers usually don’t need replacement as often as air-cooled chillers do.
  • Quiet Operation.
  • Energy Efficiency.
  • No Open Space Needed.
  • Safety.
  • Higher Cost.
  • More Maintenance.
  • Complicated Installation.

What is the purpose of a chiller?

A chiller provides consistent temperature and pressure to your industrial process. Eliminating temperature and pressure variables simplifies the process development and optimization, ensuring the highest quality product. Instead of a wasteful, single-pass-through system, a chiller recirculates the cooling water.

Can chiller provide heating?

“For typical buildings, chillers normally provide hot water for space heating at 105º to 110ºF (40.6 to 43.3ºC).” In many VAV (variable air volume) reheat applications, 105 F hot water can be used very effectively by simply specifying a 2-row reheat coil instead of a 1-row coil.

What is the useful life of a chiller?

To Repair or Replace: Where is Your Chiller in its Life Cycle? According to Consulting-Specifying Engineer Magazine, the median life cycle of a water-cooled chiller is 20-30 years, while air-cooled chillers have a life expectancy of 15-20 years.

What are the disadvantages of a liquid cooling system?

Susceptibility to leaks:Poorly implemented liquid cooling system is likely to result in leaks. Note that water or liquid coolant can accelerate the corrosion of metal parts and damage electronic components. Pressure inside tubes can also build up due to too much heat absorbed by the liquid resulting in leaks.

What are the disadvantages of air-cooled engines?

What are the disadvantages of an air-cooled engine? Air-cooled engines are more likely to overheat. They can also be more expensive to build and the large fans used to cool the engine can take away a lot of power.

How do chillers work?

A chiller works on the principle of vapor compression or vapor absorption. As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces. The refrigerant then flows to a compressor, which performs multiple functions.

How does heat recovery chillers work?

As the heat recovery chiller removes heat in the evaporator from cooling load to the condenser, and then recovers heat rejection from the condenser to the cooling tower. The higher heating water temperature is, the lower efficiency and cooling capacity is, even the chiller operates unsteadily and break down.

What is chiller components?

The main chiller components are the Compressor, Condenser, Evaporator, Expansion Valve, Power Panel, Controls unit and the Water Box.

When should you overhaul a chiller?

Generally, we recommend that commercial and industrial chillers be overhauled and inspected every 8 to 10 years or every 25,000 to 30,000 operating hours to ensure peak performance, whichever comes first.

How big of a chiller can I rent?

Both water-cooled and air-cooled chiller rentals are available in sizes from 10 to 1,000 tons. Also available is Aggreko’s line of low temperature process chiller rentals.

Why are air cooled chillers used in hospitals?

Our air-cooled rental chillers are widely used to provide supplemental, temporary, and emergency cooling for high-volume applications like hospitals, refineries, and power stations, that’s why our chillers are trailer-mounted and always ready for quick delivery. Air-cooled rental chillers install quickly and run very efficiently.

Can a CTCA water cooled chiller be rented?

CTCA’s water cooled chillers operate on approximately half of the electrical requirements of most air-cooled rental chillers.

What kind of chillers are used in industrial settings?

Low Temperature Process Chiller Rentals Designed and built for deployment in the harshest of industrial settings Environmentally-friendly, using non-CFC refrigerants Widely used to provide supplemental, temporary or emergency cooling for high-volume applications, such as at refineries or power stations.
