Air Cooled Chiller Efficiency

It is measured in cop which stands for coefficient of performance.

Air cooled chiller efficiency.

Mechanical cooling compressor cooling at low ambient conditions. Energy efficiency while water cooled chillers are best known for their energy efficiency air cooled units feature options such as electronically commutated ec fans that can help minimize energy consumption. Our robust portfolio features a wide operating map so you can find the just right solution for your building. We offer an array of tonnage sizes efficiencies and performance features to meet your requirements.

Chiller efficiency when engineers and controls specialists focus on improving chiller efficiency it is often at the detriment of the energy consumption of associated equipment such as cooling towers air distribution fans chilled water and condenser water pumps. Air cooled chiller efficiency is dependent on the temperature of the ambient air being used in its cooling system. Normally water cooled chillers are cheaper and more efficient with the disadvantage of high water consumption. As a rule of thumb the chiller efficiency can be increased by 1 2 per degree c the chilled water temperature is increased.

The higher the temperature of the circulating cooling air the less efficiently an air cooled chiller will perform. The coefficient of performance is just a ratio of the refrigeration effect produced by the chiller against the amount of electrical energy that went into the machine to produce this. Additionally the expelled heat from the cooling process can help warm facilities during colder months. Sometimes the net result is an increase in total energy consumption.

Femp has calculated that a 175 ton air cooled chiller meeting the required 10 7 eer efficiency level saves money if priced no more than 27 100 above the less efficient model. Calculating the efficiency of a chiller is fairly simple. It is cost effective up to a price premium of 128 200 above the less efficient model. High efficiency and low noise are the hallmarks of all our air cooled chillers.

The difference is that the water cooled chillers or rather the cooling towers use a humid air stream ambient air stream water spray while the air cooled chillers use a current of ambient air. The best available model saves the average user more. There are lots of ways to implement this you should first check with your chiller manufacturer if this is applicable to your chiller and ask what temperature or pressure limits should be imposed.
