How much power 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.
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 is chiller load calculated?
Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.
What is chiller Fla?
FLA – Full Load Amps: Changed in 1976 to “RLA – Rated Load Amps”.
What is a good chiller kW ton?
capacity and higher density makes water an ideal medium for space-efficient heat transfer. Whereas a typical packaged cooling unit has an efficiency of 1.1 to 1.4 kW/ton, a chiller-based system can have a full load efficiency that is far lower—values of 0.8 to 1.0 kW/ton for the entire chiller plant are typical.
What is chiller kW ton?
The term kW/ton is commonly used for larger commercial and industrial air-conditioning, heat pump and refrigeration systems. The term is defined as the ratio of energy consumption in kW to the rate of heat removal in tons at the rated condition. The lower the kW/ton the more efficient the system.
How much does it cost to replace a chiller?
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).
What is the tonnage of my chiller?
Calculate BTU/hr. = Gallons per hr x 8.33 x ΔT°F. Calculate tons of cooling capacity Tons = BTU/hr. ÷ 12,000. Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2.
What is nominal capacity of chiller?
The cooling capacity of a chiller, especially a packaged air-cooled chiller, is often described in terms of its nominal tonnage value, which is a rough approximation of the tonnage at “typical” conditions. However, nominal tonnage is really only useful as an order-of-magnitude metric for the chiller’s size.
What are LRA amps?
locked-rotor amperage (LRA) The very high current or amperage a motor draws when power is first applied, due to low counter emf. It is usually five to six times the running load amperage.
What are MCC amps?
Maximum Continuous Current (MCC). This maximum current value is referred to as the Maximum Continuous Amperage (MCA) or Maximum Continuous Current (MCC). MCC and MCA mean the same. It is the actual maximum continuous current value that the compressor’s motor protector will carry without opening.
