This practical case focuses on the configuration of a 2HP semi-hermetic piston compressor used in a -18℃ commercial freezer with an approximate volume of 20㎡. The chosen compressor comes with an input power of 1.5kW and a cooling capacity of 4.8kW, which fully meets the freezer’s cooling needs. It adopts a cast iron cylinder block with excellent heat dissipation capability, able to adapt to an evaporation temperature of -25℃ and a condensation temperature of 35℃.
The unit is equipped with a built-in oil separator, which reduces oil consumption and ensures stable lubrication of internal parts. In actual operation, the compressor maintains a steady operating current of 3.2-3.5A, with a noise level below 65dB(A). This configuration strikes a balance between cooling efficiency and energy consumption, making it highly suitable for small and medium-sized frozen food storage applications.
