Hi guys,
I'm doing some calculations on a vapor compression cycle system for my Master Thesis.
My question is:
Does the mass flow change when the refrigerant flows through the (electronic) expansion valve (assuming steady state flow)?
I assume that it doesn't but I can't seem to get...
Hi sorry for late answer. It's not an assignment it's a part of my Master Thesis. Thermodynamics is not my best field and that's why I posted this question. I need to calculate the specific heat capacity for refirgerant R-134a in three different phases; gas-phase, two-phase and liquid-phase. I...
Calculate Specific Heat Capacity HELP!
Hi guys,
I having big troubles with how to calculate the specific heat (cp) for refrigerant r134a i gas phase.
I think that assuming ideal gas behavior is a bad idea since this is going to be used in a actual system...
I have values of entropy...
Hi guys,
I'm stuck on some thermodynamic calculations and I would really appreciate some help!
I'm trying to calculate the refrigerant temperature inside of an evaporator (two-phase lumped parameter model) based on the exit temperature of the evaporator and the pressure.
I've understood that...
Hi guys,
I'm struggling with some equations regarding the enthalpy change over a compressor in a vcc system.
I'm currently working on a model for the whole system and I think I've got all equations except the one describing the enthalpy difference betweeen the inlet and outlet of the...
