An ideal refrigerant should possess the following thermal characteristics: Refrigerants which won’t corrode the mechanical components of the refrigeration systems they circulate through are highly desirable as they will reduce the cost of industrial chiller maintenance. R-134A is made of a single component and is not blended like most R-12 and R-22 alternatives are. The three major types of industrial chillers in use today are air-cooled chillers, water-cooled chillers, and evaporative condensed chillers. Type II. Because of this, working with the refrigerant does not require the use of multiple recovery machines. Please fill out the form below. used in medium to large cooling loads. Capacities range from 60 to 300 tons. Unlike hot systems, where These gases, which have very low evaporation points, are condensed under pressure to chill the air. Deciding on the type of refrigerant to use in a chiller unit, depends on industrial preferences, cost considerations and need for compliance with industrial, occupational health and environmental regulations including global warming potential (GWP). The pistons have intake and exhaust valves that can be opened on demand to allow the piston to idle, which reduces the chiller capacity as the demand for chilled water is reduced. In an evaporator , refrigerant enters as a low pressure liquid/vapor mixture and exits as a low pressure gas. Using C02 as a refrigerant is advantageous as it is non-flammable and not toxic. Types of Refrigerant. Water-cooled chiller Mainly used at the places where the heat generated by air-cooled chillers poses a problem. An additional benefit is its environment-friendly nature with a low GWP. So, what type of refrigerant is used in chillers most often? Here we have classified the evaporators based on their construction. There are two types of condensers used in chillers; air-cooled and water-cooled. If a low to medium temperature refrigerant is required for a cooling process, then R404A should be considered. They don’t need a cooling tower and condenser water pump. The liquid refrigerant reenters the expansion device and the process begins again. Another type, which is produced in large quantities, a scroll compressor, but still these compressors are not available in the amount normally encountered in industrial refrigeration.Rotary vane compressors are still used as a low stage compressors, but very little installed. Theoretically speaking, the ideal type of chiller refrigerant will possess all the following properties. The combination of the hydrofluorocarbons difluoromethane (R32), pentafluoroeethane (R125) and 1, 1, 1, 2- tetrafluoroethane (R134A) will provide heat, reduce flammability and decrease pressure respectively. But they all face the same issues relating to both condensation control and moisture. The refrigerants generally used for this purpose are ammonia (NH3), carbon dioxide (CO2), and sulfur-dioxide (SO2). It includes cold rooms, glass door merchandizers, and display and islands cabinets, either in centralized or plug-ins – hermetic or autonomous cooling circuits with condensing units. Different types of process chillers fall under two main categories: (1) Vapor Absorption and (2)Vapor Compression. The two main types of chillers are vapor compression chillers and vapor absorption chillers. The absorption cycle uses a heat-driven concentration difference to move refrigerant vapors (usually water) from the evaporator to the condenser. R-410A is a mixture of two other HFC refrigerants, R-125 and R-32, and offers greater cooling properties than older HCFC refrigerants when they are subjected to higher pressures. An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid. R134A HFC. Vapor compression chillers are the most common type of chiller. They are mostly used in applications where the heat discharged is not a factor. The test for Type II certification covers additional issues related to high- and very-high-pressure appliances, including leak detection, leak repair requirements and refrigeration.
