Numerical of Vapour Compression Refrigeration System

[@ritimech2832]

Thank you sir 2 hour before exam m watching your video

why h1 and h2 are same for subcooling upto 20 degree celcius

An ideal vapor-compression heat pump cycle with Refrigerant 134a as the working fluid provides heating at a rate of 15 kW to maintain a building at 20°C when the outside temperature is 5°C. Saturated vapor at 2.4 bar leaves the evaporator, and saturated liquid at 9 bar leaves the condenser. Calculate (a) the power input to the compressor, in kW (b) the coefficient of performance (c) the coefficient of performance of a Carnot heat pump cycle operating between thermal reservoirs at 20 and 5°C Can you solve this ?

How did u come to conclusion that the inlet of compressor has mixture of gas and liquid?

[@aistories.entertainment]

You know before expansion valve refrigerant is all vapour. When it passes through the expansion valve it expands (in the evaporator) and causes cooling. But it is not evaporated 100% so when it leaves evaporator and reaches the compressor inlet it has gas and liquid (which is still not evaporated). I hope you get the idea now.

how to apply interpolation??

[@-Dhruvit]

Sir numerical based on pH chart

[@bestmechanicalengineering]

In exam it is compulsory to solve numerical by using table only

[@ShubhamKumar-nt6vj]

​@@bestmechanicalengineeringsir which table is best for refrigeration and air conditioning. Please reply sir🙏

[@ANURAGSINGH-eg2qh]

Sir provide the pdf of table
