The reason is that it is far more efficient in comparison to the competitive refrigerants. A compressor does the job of pumping up the refrigerant through the evaporation coils and then through the condensation coils. Vapor compression is the key technology used in refrigeration systems. The temperature range and cooling ability of the system greatly depends on the refrigerant it uses. Industrial refrigeration system basics – Ammonia refrigerant. The Basics of Ammonia Refrigeration. These are factors as to why ammonia systems The most common types of refrigerations you’ll see in industrial settings are ammonia and R-134a. The refrigerant (coolant) used in such units is a vapor that compresses to become a liquid and then expands again to become a vapor. Table 1: Qualifying attributes of industrial refrigeration systems Attribute Criteria Size: 100 tons or larger Refrigerant: Ammonia (R-717) in the vast majority of cases, with some R-22 applications Also, detecting leaks in an industrial setting is easy, because it has distinct of the odor. It enables high cooling with less power, making it effective for lowering long-term operational expenses in industrial settings. Now that we have understood the basic principle of refrigeration, let us see the reason that ammonia is preferred as an industrial refrigerant. Liquid ammonia receiver tank 17. Due to Ammonia being a toxic substance you will not typically find one of these systems in any residential home. Ammonia is a colorless gas in lower concentrations. Ammonia offers a wealth of benefits for industrial refrigeration Ammonia was used for refrigeration in 1876, for the first time in a vapor compression machine by Carl Von Linde. Focus on Industrial Refrigeration This Guide focuses solely on industrial refrigeration systems, which we define in the following broad terms.
