Presenting the groundbreaking cascade refrigeration system, crafted with precision by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This revolutionary design seamlessly integrates CO2 and NH3 refrigerants to deliver unparalleled cooling capabilities. The CO2 refrigerant masterfully captures heat in the end evaporator, transferring it to the high-temperature NH3 refrigerant within the condensing evaporator. This NH3 refrigerant, carrying the heat, skillfully releases it to the surroundings through the high-temperature condenser, forming a complete and efficient refrigeration cycle.
The condensed CO2 then elegantly flows into the CO2 reservoir, continuing its journey through the CO2 gas-liquid separator via the dryer filter and throttle valve. The CO2 circulation pump efficiently channels this liquid CO2 to the CO2 evaporator, ensuring peak cooling performance. The gaseous CO2 is expertly compressed by the compressor, returning once more to the condensing evaporator, creating a seamless continuous cycle of superior cooling efficiency.
Embrace the future with unrivaled cooling efficiency and steadfast reliability through the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration infrastructure today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Enhanced safety with reduced NH3 unsafe factors:
- The NH3/CO2 cascade system brilliantly reduces NH3 condensing pressure by an impressive 1/10 compared to traditional methods.
- NH3 is meticulously confined to designated areas, significantly boosting safety.
- Harness the exceptional heat transfer properties of NH3, optimized for high-temperature regions.
- CO2 provides enhanced safety in personnel-intensive zones and warehouses.
- CO2 operates as a low-temperature work medium, capitalizing on its remarkable heat transfer efficiency.
