The difference between low-temperature cascade condenser temperature and high-temperature cascade evaporator temperature is called temperature ______

The difference between low-temperature cascade condenser temperature and high-temperature cascade evaporator temperature is called temperature ______ Correct Answer overlap

Temperature overlap is the difference between low-temperature cascade condenser temperature and high-temperature cascade evaporator temperature. Temperature overlap is a crucial phenomenon to attain higher C.O.P. because it shows the heat transfer in the system.
