Maximizing the energy-saving advantages of the CO2 cascade system in quick freezing conditions. We use our self-developed CO2 stacked block unit. According to the normalized energy consumption measurement by the owner, it has been confirmed that the energy efficiency advantage is significantly higher than that of the ammonia dual stage system and the fluorine dual stage system. The system is energy-saving, stable, easy to maintain, and has low cost. It has been fully recognized by the owner and has been cooperated with multiple times in the future.
