Because compression can improve venous circulation. This makes compressor lighter and cheaper. Keywords – Refrigeration,vapour compression,vapour absorption,refrigerant,carbondioxide. At the COP 7 meeting in Marrakech, Morocco from 29 October to 10 November 2001, negotiators wrapped up the work on the Buenos Aires Plan of Action, finalizing most of the operational details and setting the stage for nations to ratify the Kyoto Protocol. In this system, the working substance is a refrigerant like NH 3, R-11, R-12.. Advantages of multi-staging in vapor compression system: Advantages of multi-staging in vapor compression system are : 1. High superheat of the vapor in the system would cause _____. Autoencoders can be useful for many different things. 4) Heat removal during condensation is reduced hence size of condenser is reduced. As this pressure ratio is very high the size and work done required in case of a single-stage is more, thus COP decreases TO increase COP and reduce work done multi staging is needed.
