How much does a chiller cost per ton?
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.
How much does it cost to run a chiller?
As an example, consider a 500 ton water-cooled chiller that has an efficiency of 0.80 kW/ton and a $/kWh rate of $0.065/kWh. This system would cost $26,000 annually to operate if it runs 1000 hours/year.
How much does it cost to cool water?
The net result of these cost factors for cooling water have resulted with most design engineers using a “default cost” of $3.00 (USD) per 1,000 gallons of cooling water — when the actual site situation is unknown.
How do you calculate chilled water consumption?
Use the formula Q = M X C X ΔT where:
- Q = heat load in British Thermal Units per Hour (BTUH)
- M = flow in Gallons per Hour (GPM)
- C = specific heat of the fluid.
- ΔT = temperature difference in degrees Fahrenheit.
- Q = 500 BTU per gallon per hour X 40 GPM x 12 ΔT = 240,000 BTU per hour.
How much is a 200 ton chiller cost?
His research showed that a 200-ton air-cooled chiller costs approximately $250,000, while a 200-ton water-cooled chiller can run approximately $340,000.
How can I reduce the energy consumption of my chiller?
Chiller energy consumption can be reduced considerably with a decreasing approach temperature. Lowering the approach temperature can be achieved by reducing the entering condenser water temperature.
How much does it cost to run a water chiller?
How much does it cost to run a chiller? Per Tables 2 and 3, the air-cooled chiller plant would cost roughly $122,400 per year to operate compared to the $69,360 per year for the water-cooled plant. Comparing the same 200-ton chiller plant, the water-cooled plant would cost roughly $80,000 more to build.
How is chiller energy consumption calculated?
To calculate the estimated energy consumption simply multiply the rated capacity of the chiller Tons with the efficiency at full load being in kW/Ton and multiply this by the annual run hours.
How much does it cost to run a swamp cooler 24 7?
Swamp coolers will cost about $2 to run for 24 hours. To run a unit 24 hours a day, every day, for an entire month, it would cost roughly $60. In comparison, a central AC costs about $330 per month at this rate.
How chiller bill is calculated?
Consumption Charge: It is calculated according to the meter reading as per the usage. It will be charged at Dhs 0.568 fils per RT (refrigeration ton) per hour. Demand Charge: It is a recurring yearly charge.
What is a rental chiller?
Air-Cooled Chiller rental units can provide immediate emergency cooling while repair or replacement equipment is being installed. Industrial chiller rentals can also be used to cool large events or halls with little set up time required.
Do water chillers use a lot of electricity?
Chillers are responsible for over 40% of that demand, making up between 10-12% of a building’s total electricity usage and presenting an opportunity for cost savings.
Are chillers energy efficient?
Constant speed chillers also benefit, but only about 5 percent efficiency gain for every 5 degrees of chilled water relief. Although cooling tower fan energy will increase with a chilled water temperature relief strategy, chiller energy savings normally more than outweigh fan energy increases.
How is chiller energy savings calculated?
To calculate this we need to take the chillers rated capacity (kW) and multiply this by the run hours per year, then divide it by the IPLV COP efficiency and multiply this by the average load factor.
How do you calculate kilowatts per ton of chiller?
Electric motor driven chillers are rated in kilowatts per ton cooling.
- kW/ton = 12 / EER.
- kW/ton = 12 / (COP x 3.412)
- COP = EER / 3.412.
- COP = 12 / (kW/ton) / 3.412.
- EER = 12 / (kW/ton)
- EER = COP x 3.412.
How is chiller bill calculated?
Cost of Chiller charges:
- Consumption Charge: It is calculated according to the meter reading as per the usage. It will be charged at Dhs 0.568 fils per RT (refrigeration ton) per hour.
- Demand Charge: It is a recurring yearly charge.
- Fuel Surcharge: This charge is levied on the bill due to a rise in fuel prices.
Is a swamp cooler cheaper to run than AC?
Overall swamp coolers have been found to be far more energy efficient for home cooling. Swamp coolers will use 15% to 35% of the energy that most traditional AC units would use. They also do not require any chemicals in the way that traditional AC does.
Is it expensive to run a swamp cooler?
Where can I find costs of cooling water?

What is the energy cost savings calculator for air-cooled electric chillers?
This energy cost savings calculator for air-cooled electric chillers is designed as a screening tool that estimates a chiller’s lifetime energy cost savings at various efficiency levels. Learn more about the calculator assumptions and definitions. Is this a new installation or a replacement?
How much energy do chillers consume?
Chillers consume more than 50% of electrical energy during seasonal periods of building use. More than 120,000 chillers in the U.S. are expending more than 30% in additional energy through opera-tional inefficiencies. (Estimated by DOE survey)
What is a high-efficiency chiller?
High-efficiency chillers can produce chilled water using less than 0.50 kW per ton of cooling capac- ity. A refrigeration system must also reject the heat that it removes using a cooling tower for water cooling the condenser (most efficient) or using fans for air cooling the hot refrigerant of the condenser coil.
