The Vapor Compression Refrigeration Cycle, Step By Step

The Vapor Compression Refrigeration Cycle is nearly 200 years old, but it does not seem ready to leave the scene any time soon. While some people have viewed this method as environmentally harmful and inefficient, the cycle is still applicable in the industrial sphere. Natural gas plants, petroleum [..]

Electrical Safety Regulations for Chilling Plant with R717

One of the most widespread refrigerants used in the field of industrial cooling is R717 (Ammonia). The selection of the refrigerant is based on process parameters such as cooling temperature requirement, condensing pressure, plant nature, location, efficiency, etc… or simply due to availability. Usi[..]

Advanced refrigerants R1233ZD as substitute of R123

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[..]
