Expansion
Dear Forum....
I am a newbie in refrigeration.
During the expansion the refrigerant come from the higher pressusre and temperature in condenser to the lower pressure and temperature in evaporator.
I want to know... which expansion is used to expanse the refrigerant form the condenser to the evaporator .... is it isotherm ? adiabatic(isentrope) ? Which one is ideal which one real ?
How is the calculation of the outlet temperature after expansion... if the inlet temperature and pressure is known... and the pressure after expansion is also known ?
with isenthalp ? dh=0=cp dT means dT=0 ????
or adiabatic with isentropic coefficient ? how do I get this coefficient ???
Sincerely,
Yen Sindo Boentoro
