I was afraid of this topic.
Before getting to this lecture😂

Thank you go much it was helpful❤

[rockerjain]

thank you so much, such an easy and nice explanation, helped me a lot.

Thanks for the explaination sir👌but I have some uncertainity on 11:17, where you had to find T2 by relating S1 equal to S2 and I clearly get that, the thing is when looking at the T-S diagram T1 is greater than T1' (hance temperatures are difference) from that being observed. How come you used the conditions (i.e. sg) at point 1' where the temperature is 263K? since the the process from point 1'-1 is not isontropic, I was hoping we were going to first find temperature/conditions at point 1. If there's any logical explanation for the method, please clarify it Sir.🙏🙏

Hello, here refrigerating effect will be T1 dash - T4, T1 dash to T1 is superheating process so do we consider this as refrigerating effect

hi sir,
In the previous numeric problem on finding COP you have considered degree of superheat and sub cool as Evap temp-degree of superheat, similarly Condensing temp-degree of sub while considering Delta T ( temp diff)
But in the above lecture you have directly put delta T as degree of superheat

please clear the doubt

if s1=s2 then how did you just simply added everything?
and how did you added 267 kelvin and 7 degree Celsius?

Can you explain the subcooling correction for the following, R404a, SST : -31.67°C, SDT: 40.56°C, Compressor Suction Temperature : 3.62°C, Liquid temperature : 9.57°C, Degree of Superheat : 36.53°C, Degree of Subcooling :30.99°C and refrigerating effect ( cooling capacity) : 6710 watts..i need to correct the capacity to zero( 0 ) Subcooling from 30.99°C..Can you explain ?

How did u calculated natural log in entropy equation

[pujithak]

For every model of this problem we can do like this?

[shashankmukhi]

while calculating COP superheat part is included or not

[Ratna]

Can you explain the calculation for subcooling correction ?

[manoj]

I have a question on Mass flow rate calculation. How to calculate it if refrigerating capacity is not known?

[shashankmukhi]

Hi just want to confirm u have taken COP h1- h4 not h1' - h4

[sahilparmar]

In standard while calculating T2 you took S1=S2 in a different way and in this different

[agordat]

Sir can you upload a lecture making the above calculation using Coolpack software?
