The refrigeration cycle removes unwanted heat from one place and discharges that heat in another area. The process is accomplished, in short, by the pumping of refrigerant through a closed system. This system is composed of several components which enable the process to work. In the realm of industr[..]

As new environmental concerns and regulations appear, the ammonia chillerstands out among the many ways both science and the industry are looking to implement new strategies for cooling.

From power generation to refrigeration systems, the centrifugal compressor is living a golden age as a piece of equipment. In a context in which achieving the maximum efficiency has become a much sought-after target, the centrifugal compressor has become a key component of many systems. Here’s a loo[..]

We frequently use ammonia refrigeration systems for very large cooling applications, such as Industrial Refrigeration. Chillers using ammonia are becoming commonplace in green buildings and may be a viable option for District Cooling systems. As refrigerant legislation continues to get tighter, enco[..]

The debate over what is “the best” commercial refrigerant has been around and is unlikely to end anytime soon. Intensity on this matter is even increasing as leakage studies reveal the adverse effects of HFC emissions. The only way out for centralized systems is emissions reduction, which while poss[..]

The original design of an absorption chiller is credited to the likes of Ferdinand Carré, Carl Munters and Baltzar Von Platen, renowned scientists who did their works between the 1850s and 1920s. While the products were first produced commercially in 1923, it was only in the 60s that serious product[..]

With the increasing need for refrigeration, compressors are being developed in numbers and with better technology. However, the basics still stand. With the many refrigeration compressor types available, selecting one for your application can be overwhelming. Some factors to consider for the best un[..]

It is very rare not to find a heat exchanger in a modern industrial plant. The heat exchangers are so critical to the plant’s operations that they may even determine the overall energy efficiency. Designing a good heat exchanger encompasses maintainability and types of fluids used, but we will try t[..]

What is an ideal industrial refrigerant? There is no absolute answer to this question. No refrigerant fits the requirements 100 % for all cooling plants. An ideal refrigerant would need to have it all in terms of material compatibility, chemical stability, performance, non-toxicity, non-flammability[..]

Pressure tests are a non-destructive way to guarantee the integrity of equipment such as pressure vessels, pipelines, plumbing lines, gas cylinders, boilers and fuel tanks. It is required by the piping codes to confirm that a piping system is able to bear its rated pressure and it has no leaks. Pres[..]

The whole world is experiencing a big and unavoidable change in terms of lifestyle and work habits. New technologies, machine learning, IoT (Internet of Things) and the upcoming establishment of the 5G technology is creating an extremely big amount of digital data; and here it is where the data cent[..]

About 25% of greenhouse effect emanates from the industrial sector, either directly or indirectly. Construction, food processing, mining and manufacturing are key industrial subsectors where diverse processes result in direct CO2 emissions. Power and heat require a lot of fossil fuel combustion.
