VCRS

what is the part of a vapour compression refrigeration system to which if u remove from the system then it will stop working?

I don't understand whether you are asking your doubts or testing others knowledge.
sorry if you get hurt by my words

A vapor compression refrigeration system has four main parts
1.Compressor
2.Evaporator
3.Expansion valve
4.Condenser
Each part is vital for completing the vapor compression refrigeration cycle.

I don't know what kind of question is this?. If you remove a component from a system and if its still working then its either a back up or dead weight. As far as i know backups are not essential for refrigerating units and dead weights in any industry just adds to the cost.

u are not g

u r not getting my question...i am explaning again that i was asking that what is the specific component in vcr system to which if u will remove from this system then its c.o.p will be equal to "zero" then obviously it will stop working...and i want to tell u one thing more that except that specific component if u will remove other component then it will work but will not be useful for refrigeration purpose,,,and it is very intresting question sir...

I guess you are not understanding the concept well, if you remove either of the four the system would stop working.

explain entropy please

If any one of the components is not present then the system wont work.

sysyem will work but will not give required effect...

i think that if u will remove expansion valve then the system will stop working because its c.o.p will become zero..and except expansion valve if u will remove any another component then it will not stop working but will not give desired effect...

de

degree of randomness of molecule is called entropy of any system...if randomness will increase then entropy will also increase and if it will decrease then entropy will also decrease...

explain adiabatic isotropic isentropic process

A system is said to be working only when it gives the desired output. Otherwise no matter what it does it wont be considered working. Achieving a compression or expansion alone is not the function of vcrs system. As far as technical terms concern the system wont work even if you remove any one of the four basic components of vcrs.

ok..working of a system and desired output both are different things...i was asking about stop working totaly...and there is only one component named expansion valve to which if u will remove it will stop working totaly...but if u will remove any another component then it will not give desired output but it will work....

adia

adiabatic process is a process in which there no heat transfer takes place and reversible adiabatic process is called isentropic process in which entopy remains constant ..........both are ideal process which are not possible in practical life...

and

and ok pradeep sir just stop discusson on this matter...a/c to me its possible and a/c to u its not possible..so thanks sir for ur coorporation...thanks a lot...

@nibhani

now that is one interesting question. you can give the answer, and explain it in more detail.

So what output are we expecting?

we are expecting higher c.o.p as output...
