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[..]

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. [..]

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[..]

Modular chiller plant: in which cases are they convenient?

Since 1902 when Willis Haviland Carrier invented world’s first modern air conditioning system, the air conditioning technology has grown tremendously to today, when the chiller is not only energy efficient, but also user friendly. ARANER is one of the respected providers of this solution. In this po[..]
