Step into a new era of refrigeration with the groundbreaking cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Designed with precision, this state-of-the-art system utilizes the powerful combination of CO2 and NH3 refrigerants to deliver unparalleled cooling efficiency. The innovative mechanism begins as the CO2 refrigerant absorbs heat in the end evaporator, seamlessly transferring it to the high-temperature NH3 refrigerant within the condensing evaporator. Completing this remarkable cycle, the NH3 refrigerant then expels heat into the atmosphere through the high-temperature condenser, ensuring a flawless, continuous refrigeration experience.
The journey continues as the condensed CO2 makes its way into the CO2 reservoir, advancing through the CO2 gas-liquid separator, and expertly traversing the dryer filter and throttle valve. Enhanced by the precision-driven CO2 circulation pump, the liquid CO2 powers into the CO2 evaporator for optimal cooling performance. Meanwhile, the gaseous CO2 is expertly compressed back to the condensing evaporator, perpetuating a seamless cycle that guarantees supreme cooling efficiency.
Unlock a new realm of cooling prowess and dependability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Propel your refrigeration capabilities to unprecedented heights today!
Advantages of NH3/CO2 Cascade Refrigeration System
Features:
- Reduced NH3 unsafe factors:
- The NH3/CO2 cascade system ingeniously diminishes NH3 condensing pressure by an impressive 1/10 compared to traditional systems, setting a new benchmark for safety and efficiency.
- NH3 is strategically confined to designated zones, significantly enhancing operational safety.
- Harnessing the efficient heat transfer properties of NH3, this system excels in high-temperature environments, maximizing heat dissipation.
- CO2 ensures a secure environment in personnel-centric areas and storage warehouses, prioritizing safety.
- CO2 acts as a formidable low-temperature work medium, leveraging its outstanding heat transfer capabilities for superior performance.
