The performance curve of a vapor-compression refrigeration cycle illustrates how the system’s efficiency varies under different operating conditions. Typically, such a system comprises a condensing unit (CDU) and an evaporator. The individual performance curves of these components are plotted and analyzed collectively to evaluate the overall system performance when operating in tandem.
This note illustrates the performance curve of the condensing unit (CDU). For evaporator performance you can find in Performance for vapor compression refrigeration cycle – Evaporator or DX coil.
