Refrigeration cycle process
WebThe simple refrigeration cycle consists of four main processes: compression, condensation, expansion, and evaporation. These processes take place respectively in the compressor, condenser, expansion valve, and evaporator. WebThe vapor compression refrigeration cycle is a common method for transferring heat from a low temperature to a high temperature. The above figure shows the objectives of …

WebAir cycle refrigeration works on the reverse Brayton or Joule cycle. Air is compressed and then heat removed; this air is then expanded to a lower temperature than before it was compressed. Heat can then be extracted to provide useful cooling, returning the air to its original state (see Fig. 2.15 ).
WebVapour-compression refrigeration or vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for chilled or … WebDespite the fact that the picture depicts three compressors, base your calculations on one compressor running. Refrigeration cycle: Refrigerant is superheated by 7∘C at evaporator exits of freezing room, fish-meat room, and vegetable room. Refrigerant is sub-cooled by 5∘C at condenser exit. Compressor's isentropic efficiency is ηise.
WebThe vapour compression cycle in the refrigeration system is working at expansion valve in the law of Steady Flow Energy Equation, h 3 + Q = h 4 + W. We know, value of Q and W is 0. So, we can write, h 3 = h 4. Performance of vapour compression cycle in the refrigeration system is, Output/Input = h1 – h4/h2 – h1.
