1. hope this inventor got a nobel prize
2. When the liquid exits the expansion valve, it will also have the vapor exiting with it. The liquid will be much cooler than the vapor correct? so will the vapor hinder the subsequent step, which is the cooling of the objects in the refrigerator?
3. There is no such icon for number of likes ,otherwise I could give thousands of Likes.
4. sir can u plz xplain isothermal compression and isothermal xpansion processes briefly???since ther is a variation in temp coming out from compressor and the temp leaving the condenser..
5. The heat required for evaporation comes from within the refrigerant so its temperature drops ?? I don't really know how to make sense of this.. where does the heat go within this process then ?
6. so how does some part of fridge come cooler than other parts?
7. Nice
8. You just saved my Bachelor Degree.
9. Thank you very much. It is a simple and easy to understand the fundamentals of the refrigeration syscle. It helps me to understand about the refrigeration principles. Thank you.
10. To help understand the process of refrigeration first let's talk about the 2nd law of thermodynamics heat moves to what is colder lower then 1* degree difference..so a evaporator coil is 35* f* and the air going across it is 40* the evaporator absorbs the heat from the product to be cooled causing liquid to turn into a low pressure,low temperature,super heated vapor entering the compressor which cools the Hermetic compressor discharging high pressure, high temperature, superheated vapor entering the condenser coil 100* degrees, where the absorbed heat from the evaporator and compressor is now rejected by catching a ride on 90* degree air.
    Remember."Heat travels to cold") leaving the condenser a subcooled liquid, traveling through the filter drier to collect any moisture or burrs (hope not) then maybe a sight glass so u can see liquid going to the metering device where a pressure drop occurs liquid,vapor called flash gas to the evaporator coil for the process to continue called..Refrigeration Cycle
11. i love you thankyou so much. 4th year eng student understanding this for the first time rather than a mindless process with numbers
12. Almost the same as Airconditioning.
13. My ref doesn't have a thermostat which is continuously freezing. I wonder if does it increase my electricity bill?
14. Now I know why my mom says don't use the refrigerator to cool your baked food.
15. sry but this isn't simplistic enough to get a proper clear understanding of the process..
16. Nice video, thank you.
17. "This is what inside a refrigerator"
18. Nice
19. so is the bottom shelf the coldest?
20. Great......
    Carry on guys......
