Informative video

[@mayanksen9815]

Sir thank you for the amazing and effective video lectures. My question was why are refrigerators (fridge) defined in litres capacity Nd ac's in tonnes ?

[@vishwas718]

Sir kindly check that EER is equal to 3.413 COP and not 0.293 COP

[@Rahulmishra07]

Dear sir, pause the video at 8:25 and kindly review the blunder. Ft^2/10.764 = m^2. Which means ft is a bigger unit than meter. Kindly correct it. 🙏

[@vishwas718]

I think it is correct. To convert m^2 in to ft^ you have to multiply with 10.764 . Like km is big unit but to convert km. In to m. You have to multiply with 1000.

Sir m^2 /10.764 = ft^2.. I think you have mistakenly written wrong expression. Please make it clear 🙏

Can 0.5 ton rotary compressor replace with hermetic (HBP)compressor on windows ac?

[@vasusrivastava8638]

Sir eer=0.293×cop hona chahye

[@HarshitSingh-tb3pf]

Sir I think heat pump work on the same cycle as that of refrigerator (not reversed). Its only the desired effects which gets changed.

[@rvelmurugan8513]

No. It's reversed cycle @Harshit Singh. Same Unit act reversely when its comes to winter season
