How much does a chiller cost?
For centrifugal chillers over 400 tons, prices range from $200 to $500 per ton for the chiller itself; for centrifugal chillers less than 400 tons, prices range from $250 to $600 per ton for the chiller itself.
How much does a 500 ton chiller cost?
The following analysis compares two 500-ton chiller systems, one with an air-cooled system, and the other with a water-cooled system….Also Provides Reduction in Peak Demand.
|500 Ton System||Water Cooled System||Air Cooled System|
|(One-time cost)||$ 242,033||$ 188,200|
What is a water chiller system?
A water chiller is a device used to lower the temperature of water. Most chillers use refrigerant in a closed loop system to facilitate heat exchange from water where the refrigerant is then pumped to a location where the waste heat is transferred to the atmosphere.
How efficient are water chillers?
In general, centrifugal chillers with variable speed drives can typically see a 10 percent to 13 percent efficiency gain for every 5 degrees of condenser water temperature relief. Constant speed chillers also benefit, but only about 5 percent efficiency gain for every 5 degrees of chilled water relief.
How much does a 1000 ton chiller cost?
Air-cooled chiller costs vary by manufacturer, location, and technology options. A survey of the major manufacturers shows an average cost for the chiller itself of approximately $350 to $1,000 per ton, depending on capacity (see Table 2).
How is water cooled chiller efficiency calculated?
Take for example a chiller which is producing 2,500kW of cooling or 8,533,364BTU/h in metric units. The electrical power demand of the chiller to produce this is 460kW. The metric calculation would be: 2,500kW / 460kW = 5.4 so the COP is 5.4.
How can calculate chiller efficiency?
How to Calculate Chiller Efficiency
- Chiller water flows through heat exchangers.
- Calculate the chiller capacity in tons of refrigeration.
- Calculate the system efficiency by the air conditioning efficiency formula EER = Btu/hr cooling/watts consumed.
- Live lobsters must be chilled on their way to market.
How much is a 200 ton chiller cost?
The average cost of an air-cooled chiller plant is roughly $1,300/ton while the water-cooled chiller plant is approximately $1,700/ton. For the same 200-ton chiller plant, the cost of the air-cooled chiller plant would be roughly $260,000 compared to the $340,000 to $400,000 water-cooled chiller plant.
How much electricity does a chiller use?
They can consume approximately 20 percent of a building’s total electricity. Inefficient chillers can waste significant amounts of electricity, and even modest improvements in efficiency may yield substantial energy savings and attractive paybacks.
