Refrigeration Cycle Introduction

Organized by textbook: learncheme.com/ Explains each step in a refrigeration cycle and the energy balance for each step. The process is shown in a pressure-enthalpy diagram. An interactive simulation that also demonstrates the behavior is available at demonstrations....

This is the ultimate summary of the overall subject on the internet or anywhere.

Very nice explainations sir👍

[@balramsakya6578]

Good sir

[@gooddeedsleadto7499]

How pressure remains constant in condenser despite the temperature drop from superheat rejection after compressor & sub-cooling heat rejection before expansion valve? Thank u How pressure remains constant in evaporator despite temperature rise from superheat gain before compressor?

[@kadekevin566]

why did we compress the vapor at the stage 2?

[@KarlAlfredRoemer]

I think it gets compressed between 2 und 3.

[@Thevisualrealm2106]

To increase the pressure and temp of the Gas.

[@pedrovaz8150]

@@Thevisualrealm2106 and why?

[@yassergomaa1882]

@@pedrovaz8150 u increase the temp and pressure so that it be higher than the surrounding and then Q of condenser could transfer from higher to lower

[@patientson]

It's needed as vapour inside the compressor which always needs vapour as last product from the evaporator. When the compressor gets vapour from the suction line it presses/ compresses/ pressurises the vapour to a even higher pressure vapour ready for the condenser's discharge line where the superheat starts to get de superheat

don't get me wrong but you have to improve your explaining ability

[@abdulrehmankhan4860]

Where does the heat goes when expanding the gas in throttle vale

[@kickboxerinsj13]

If I understand my thermodynamics well enough, I think he may have missed the idea that energy can be transferred by Heat (VERY similar to Work but on a much smaller scale, usually in the atomic region) or by Work. When the fluid expands it takes up more Volume, and essentially uses Energy to expand itself at a molecular level, which in turn causes a Temperature drop as it does. If that doesn't quite answer your question, look into Enthalpy and it's formula, I think it pretty much covers what you're asking.
