Efficiency optimization for cooling plants


In most developed countries, a large amount of energy use of about 6% of the total is for air conditioning and refrigeration. The same is true for many hot countries where air conditioning systems use up to 40% of energy in the cities, and this could be a major problem as developing economies continue to grow.

Sequence management for chiller plants


When it comes to chilled water plant optimization, the control strategy based on management of individual water chillers is not an optimum approach to achieve the best results in terms of energy efficiency.

Individual control of the water chillers with common pipework will cause unnecessary cycling of compressors and associated excessive power consumption as a response to changes in cooling demand; consequently, compressor cycling will lead to unstable return water temperature and increased wear of compressors.
