## 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

1. Chiller water flows through heat exchangers.
2. Calculate the chiller capacity in tons of refrigeration.
3. Calculate the system efficiency by the air conditioning efficiency formula EER = Btu/hr cooling/watts consumed.
4. 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.
