The studies involve measuring the flow cooling water, differential temperature across all the major cooling water heat exchangers to assess operating load on the individual equipment. The overall operating load & cooling effect generated by various cooling towers is also computed based on the physical measurements. The values are matched with the overall data to assess gaps and identify potential savings / improvement areas.
Measuring the flow of cooling water at the cooling tower inlet with non-contact ultrasonic transit time flow meter
Gauging temperature drop across the cooling tower with digital temperature indicator
Computing Overall Cooling Effect
Noting down / assessing average cooling effect delivered by the system
Measuring the flow of cooling water for all the major consumers
Gauging temperature rise across the individual consumers
Computing Heat Load the individual consumers
Noting down the key other parameters like operating period, load variations

A team of two engineers is deputed to carry out the studies and furnishing the report. The field visit is
typically for 5 to 6 hours; during which up to 16 measurements can be carried out depending upon initial
preparations, type & conditions of units and support from the plant team.
Although not a part of regular assignment, the following parameters of the Outdoor Unit & Compressors can
also be also measured, if possible and requested by the plant
Measuring the flow of the process fluid for the corresponding consumers
Gauging temperature drop for the individual consumers
Computing Process Heat Load the individual consumers and comparing the same with cooling water load
Measuring the cooling water pressure at the inlet and outlet of the corresponding consumers
Computing pressure drop for the individual consumers
Measuring the cooling water pressure at various locations on the cooling water distribution network
Computing pressure drop across major sections of the cooling water network
Analysing the losses and suggesting ways for improvement, as applicable
