Fouling in heat exchangers: reduce deposit accumulation

Heat exchangers are totally necessary in the refrigeration cycle: as shown in the diagram below, two out of the four basic steps in the refrigerant cycle are heat exchangers! Their operation affects greatly to the overall plant efficiency, so their maintenance is very important. Heat exchangers, lik[..]

Centrifugal pump design and applications

Most of the industrial processes include the conduction of fluids or energy transfer. This is possible thanks to the centrifugal pumps which are the most popular turbomachinery. The growth and improvement of the industrial processes have been always linked to the improvements in the pumping equipmen[..]

Thermal Energy Storage

Thermal Energy Storage Technologies Comparison

Thermal energy storage (TES) is the process of collecting thermal energy for future use. Thermal energy storage operates like a battery, using a combination of cooling equipment and energy storage tank to transfer cooling production to off-peak hours, usually nighttime. Ice or chilled water that is [..]

Which factors will affect the chiller sizing process?

An industrial chiller protects processing equipment despite costing a small fraction of most of these facilities. It also increases production, specifically enhancing accuracy and speed of production in food, beverage, and pharmaceutical among other industries. Therefore, it is a no brainer that the[..]

Basics of fogging system for inlet air-cooling

Hot and humid summer weather affects turbine performance substantially, yet this is the most critical time for power plant service to users. A knee-jerk reaction would be to enhance installed turbine capacity to offset the deficit created by subdued performance and increased power demand. Instead of[..]

Indicators and improvements for power plant efficiency

The average temperature for most tropical regions is about 35° C. This and the accompanying high humidity spells doom for power plants in such regions unless something is done to counter the effects. Large scale power-generation relies on gas turbines, which have limitations at higher temperatures. [..]

District cooling companies: Using Remote Integrated Condensation

Most modern cities use more than 25 % of their electricity for air conditioning. Providing comfort in public spaces such as hospitals and offices has become a necessity nowadays. At the same time, energy efficiency is something the society cannot afford to ignore with the skyrocketing electricity co[..]

Chiller plant design calculation: Detailed Cooling Profile Simulation

Less than three decades ago, full load kW/ton was still a widely used metric of chiller efficiency. It was only in the late 1980s that stakeholders in the industry realized that this indication was incomplete because full load conditions are rare in real life situations. That was the beginning of be[..]

Power Augmentation: Evaporative Cooling vs. TIAC with Chillers

Did you know that it is common for electricity prices to increase with increasing temperatures? Power markets globally are suffering due to this state of affairs. Homesteads switch on their air conditioners to fight off the heat. Unfortunately, gas turbines are at their worst performance at high tem[..]

NPLV rating system application for chilled water plants

According some studies made in Middle East, chillers use over 40 % of all the energy in industrial and commercial space cooling. Therefore, it is understandable that designers are concerned about chiller efficiency. Several factors — poor maintenance, poor operation, improper sizing, etc affect this[..]
