Figure 1-5 Refrigeration Cycle on the P-H Diagram Take the structure image of this refrigeration cycle from Figure 1-5, it becomes the P-H diagram for engineering calculation as shown in Figure 1-6. The points which are required for engineering calculation are from H 1 to H PDF How does basic refrigeration cycle work? This is how the refrigeration cycle diagram looks: Yeah, it seems complicated at first, but it will be easier to understand once I have explained the refrigeration cycle diagram section by section. It important to understand the basic refrigeration cycle, to comprehend what is going on within the air conditioner units, we cannot see it. Chapter 10: Refrigeration Cycles Chapter 10-5 The P-h diagram is another convenient diagram often used to illustrate the refrigeration cycle. The ordinary household refrigerator is a good example of the application of this cycle. Results of First and Second Law Analysis for Steady-Flow PDF UNIT 2 REFRIGERATION CYCLE Refrigeration Cycle Refrigeration cycle is the basis of all refrigeration systems. So refrigeration cycle should be known to understand the refrigeration system. Some basic refrigeration cycles are discussed here through different diagrams. 2.2 VAPOUR COMPRESSION CYCLE Vapour compression cycle is an improved type of air refrigeration cycle in which a suitable ...
