I. Introduction
As technology and industry advance, low-temperature refrigeration plays a crucial role across various sectors. What is the cascade refrigeration system? It is a refrigeration system that utilizes two or more different refrigerants operating at different temperature ranges to achieve extremely low temperatures. For more details, see Wikipedia on Cascade Refrigeration and Frigel’s Cascade Refrigeration System. What is the purpose of a cascade system? Its main purpose is to overcome the temperature limitations of a single refrigeration cycle, providing lower temperature environments to meet the demands of special applications.
II. Working Principle of Cascade Refrigeration Systems
How does a cascade air system work? A cascade refrigeration system connects two independent refrigeration cycles (high-temperature stage and low-temperature stage). The high-temperature stage uses primary refrigerant R404, and the low-temperature stage uses secondary refrigerant R23. For a deeper understanding, refer to Natural Refrigerants on Cascade Systems and ScienceDirect on Auto-Cascade Systems. The two stages exchange heat through an intermediate heat exchanger, forming a cascade cycle that achieves lower temperatures. Cascade refrigeration system P-h diagram analysis helps in understanding the thermodynamic changes at each stage of the refrigeration process, providing deeper insights into the system’s operation.
