UNIT 1: REFRIGERATION AND AIR CONDITIONING
ignou.ac.in6 Refrigeration and Air Conditioning It is a well-known fact that the spoilage of food and many other items reduces at a lower temperature. At a lower temperature, molecular motion slows down and the growth of bacteria that causes food spoilage also retards.
OIL IN REFRIGERATION SYSTEMS - RSES
www.rses.orgOil is used in refrigeration systems to lubricate compressor bearings and other moving parts. The properties of the oil selected must be suitable for this purpose. In an automotive engine, motor oil stays in the crankcase where it belongs. If refrigerant oil did the same thing—that is, if it remained in the

CO2 Transcritical Systems Training Manual 042718
www.hussmann.comoxygen for breathing. At typical commercial refrigeration temperatures, CO 2 operates at a higher pressure than synthetic refrigerants. When released at these pressures to the atmosphere, CO 2 can change phase to solid form, causing restrictions in the flow that can lead to a buildup in pressure. Asphyxiation As an A1 refrigerant, CO
Refrigeration Cycle - Simon Fraser University
www.sfu.caThe ideal compression refrigeration cycle is not an internally reversible cycle, since it involves throttling which is an irreversible process. If the expansion valve (throttling device) were replaced by an isentropic turbine, the refrigerant would enter the evaporator at state 4s. As a result the refrigeration …
