What is the relation between m1, m2, and m3? If m1 = mass of refrigerant passing through the evaporator m2 = mass of refrigerant passing through the condenser m3 = mass of liquid evaporated in the intercooler

What is the relation between m1, m2, and m3? If m1 = mass of refrigerant passing through the evaporator m2 = mass of refrigerant passing through the condenser m3 = mass of liquid evaporated in the intercooler Correct Answer m3 = m2 – m1

The high-pressure compressor will compress the mass of refrigerant discharging from the low-pressure compressor (m1) and the mass of liquid evaporated in the liquid intercooler during intercooling or de-superheating of superheated vapor refrigerant from the low-pressure compressor. So, the mass of liquid evaporated in the intercooler is equal to the difference between the mass of refrigerant passing through the condenser and the mass of refrigerant passing through the evaporator, from the diagram. Hence, m3 = m2 – m1.
