TO THE TRAINER This PowerPoint presentation can be used to train people about the basics of refrigeration and air condonditioning. Centrifugal compressors (also known as turbo-compressors) are radial flow type, roto-dynamic compressors. Transported from colder regions, 2. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. See our User Agreement and Privacy Policy. M�! Individual knowledge of the equipments is required to understand the refrigeration system. The type of oil may be mineral or synthetic to suit the compressor type, and also chosen so as not to react with the refrigerant type and other components in the system. Rotary Compressors • Rotary compressor function is in which fixed amount of air is displaced with each revolution. SCROLL TYPE COMPRESSOR • A scroll compressor operating in reverse is known as a scroll expander, and can be used to generate mechanical work from the expansion of a fluid, compressed air or gas. To help you get ahead of the curve, we’ve broken down each one in some summaries below. These systems consist of an evaporator, a condenser, a compressor and an expansion valve.

Compressor Types Refrigeration Compressors Figure 4 centrifugal scroll reciprocating helical-rotary Figure 5. In other words, refrigeration is artificial (human-made) cooling. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. The third type of rotary compressor is the vane type. In other words in this type of refrigeration system compressor and condenser are not combined together in a single unit. 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. Prevent possible explosion by relieving pressure caused by fire, coil blockage, or overheating of unit. 0000034409 00000 n CHEMICAL PROCESS TECHNOLOGY TYPES OF COMPRESSORS USED IN CHEMICAL INDUSTRY 2. 2 types currently used, spring loaded and fusible metal plug As air comes in through the inlet, rotating vanes push the air along into a tighter and tighter edge of the circle, effectively compressing it while using minimal effort and travel of the air itself.
