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. This means that for every 1kW of electricity you put into the machine, you will produce 5.4kW of cooling. The imperial calculation would be: First convert BTU''s to kW''s. 8,533,364BTU/s / 3412.142 =

Chillers are often used in buildings, factories, and various industrial processes to control temperature or provide a comfortable environment. They work by

It is the amount of heat required to raise the temperature of one pound of water by 1 degree Fahrenheit. BTU is calculated by multiplying the number of pounds (lbs) by the number of degrees Fahrenheit (°F) that a chiller needs to be cooled or heated. For example, if you want to cool your chiller from 95°F to 75°F, you would need 5.2 BTUs

1. At a given ECWT for a chiller using a CSD, the specific consumption is at its optimum closer to full-load (100 percent) conditions. However, for a chiller using a VSD, the specific consumption improves as the load is reduced. 2. Even at full-load conditions, the

By multiplying the efficiency by the cooling load, we get the hourly kWh consumption. Chiller replacement, based on historic load kW/ton. Then we can see that the existing chiller would consume 1,378 kWh a day whereas the new potential chiller would consume 980 kWh a day resulting in a saving of 398 kWh.

Chillers commonly use a water/glycol solution to remove heat, transfer the fluid through the industrial process, and recirculate to form a cooling loop explicitly designed for the industrial process. This allows

Pool chillers, also known as pool coolers, work much like air conditioners by circulating hot water through a cooling system before releasing it into the pool again. They are useful in very hot regions, have long lifespans, restrict algae growth, and allow for superior control over your pool temperature. Alternatives to cooling down your pool

So, I did some studies. Chiller economizer produces cold refrigerant that subcools the main refrigerant line after the condenser to extend the condensation process thereby increasing the refrigeration

Traditionally, chiller plants are controlled and monitored by a predetermined control strategy to ensure appropriate operation based on the designed system configuration. With the use of new technology of variable speed drive (VSD) for compressors, smart control

The typicalCOP values of chillers using different heat rejecting media are shown in Figure 5 (Bitzer Software 2019;v6.10.0rev2160, 2019) gure 6 further presents the COPof chillers using different compressors and condensers based on specifications provided

Chiller Efficiency = Power Consumption (kW) ÷ Chiller Capacity (RT)Chiller Efficiency = 164.9 ÷ (890 x 3412÷ 12000)Chiller Efficiency = 0.65 kW/Ton. Using the same principle, you can always calculate the kW/Ton of a chiller even though the chiller''s cooling capacity is stated in units other than RT.
