Discover the remarkable cascade refrigeration system brought to you by Qingdao Bingyan Refrigeration Equipment Co., Ltd. This state-of-the-art system is a marvel of engineering, expertly transferring heat load using the dynamic duo of CO2 and NH3 refrigerants. Our system guarantees unmatched cooling excellence. The ingenious design begins with CO2 refrigerant, adeptly absorbing heat in the end evaporator. This heat is then transferred to the robust high-temperature NH3 refrigerant within the condensing evaporator. Completing the cooling cycle, the high-temperature NH3 refrigerant skillfully dispels heat to the environment via the high-temperature condenser.
The cycle continues as condensed CO2 is expertly guided into the CO2 reservoir, seamlessly traversing the CO2 gas-liquid separator through the dryer filter and throttle valve. The CO2 circulation pump plays a pivotal role, directing liquid CO2 to the CO2 evaporator for maximum cooling efficiency. Meanwhile, the gaseous CO2, compressed by the compressor, makes its way back to the condensing evaporator, ensuring a seamless and persistent cycle for peak cooling performance.
Step into a new realm of cooling efficiency and unwavering reliability with the cascade refrigeration system from Qingdao Bingyan Refrigeration Equipment Co., Ltd. Elevate your refrigeration systems to new heights today!
