Introducing the groundbreaking cascade refrigeration system, exclusively from Qingdao Bingyan Refrigeration Equipment Co., Ltd. This advanced system orchestrates a harmonious transfer of heat load utilizing the robust capabilities of CO2 and NH3 refrigerants, delivering unmatched cooling performance. In this artful system, CO2 refrigerant masterfully absorbs heat within the end evaporator, subsequently passing it to the high-temperature NH3 refrigerant engaged in the condensing evaporator. The high-temperature NH3 refrigerant skillfully dissipates heat into the environment via the high-temperature condenser, thus completing the sophisticated refrigeration cycle.
The process continues as the condensed CO2 seamlessly moves into the CO2 reservoir, subsequently navigating through the CO2 gas-liquid separator, assisted by the dryer filter and throttle valve. Empowered by the CO2 circulation pump, liquid CO2 is expertly channeled to the CO2 evaporator, achieving efficient cooling with precision. Meanwhile, the gaseous CO2 undergoes compression by the compressor, returning to the condensing evaporator to ensure an uninterrupted cycle of excellence in cooling performance.
Immerse yourself in the unparalleled cooling efficiency and dependability offered by the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration solutions today!
Unveiling the Advantages of the NH3/CO2 Cascade Refrigeration System
Distinctive Features:
- Minimized NH3 Safety Concerns:
- The NH3/CO2 cascade system ingeniously reduces NH3 condensing pressure to a mere 1/10 of what traditional systems require.
- NH3 is strategically confined to specific areas, significantly bolstering safety measures.
- Harnessing the efficient heat transfer properties of NH3 in high-temperature regions optimizes performance.
- CO2 provides an added layer of safety in areas with high personnel density and storage facilities.
- Functioning as a low-temperature work medium, CO2 leverages its superior heat transfer efficiency to great effect.
