Is an ideal cycle possible? In a lab experiment that I have carried out, my enthalpy values for the cycle and the cycle assuming isentropic compression look like they are the same. I thought this was impossible but I am doubting myself now?

Thanks

An ideal cycle is not achievable in reality due to irreversibilities. However, you may get arbitrarily close. What does your lab consist of exactly?

We had a refrigeration setup and we varied the evaporator volts which varied the pressure whilst keeping the condensor pressure constant. At one particular pressure, the specific enthalpy and specific enthalpy (based on isentropic compression) are very close if not the same.
