NH3/CO2 Cascade Refrigeration System: A revolutionary approach in industrial cooling, designed to maximize efficiency and safety.
1. NH3/CO2: The Principle of Cascade Refrigeration System: A sophisticated dual-stage mechanism harmonizing NH3 and CO2 for superior cooling performance.
NH3/CO2, the cascade refrigeration system is ingeniously divided into two distinct stages: the high-temperature stage employs NH3, while the low-temperature stage utilizes CO2. In this innovative design, NH3 evaporates at the high-temperature level to efficiently condense CO2 emitted from the low-temperature stage. A specialized condensation evaporator seamlessly interconnects these stages, functioning dually as the CO2 condenser and the NH3 evaporator.
The heat load is expertly transferred to the CO2 refrigerant via the end evaporator, which then channels absorbed heat to the high-temperature NH3 refrigerant. This leads to the NH3 refrigerant passing heat to the high-temperature condenser and subsequently releasing it to the environment through a cooling medium. Condensed CO2 flows into the CO2 reservoir, and continues through the system via a gas-liquid separator, dryer filter, and throttle valve. Liquid CO2 is circulated to the CO2 evaporator by a CO2 circulation pump, completing a sophisticated, ongoing cascade refrigeration cycle that ensures optimal cooling consistency.
NH3/CO2 cascade refrigeration system thoughtfully separates high and low-temperature levels into unique single-refrigerant systems. The high-temperature NH3 refrigeration system mirrors conventional setups, including a compressor, condenser, liquid storage, gas-liquid separator, and throttling device. Meanwhile, the low-temperature CO2 system comprises a CO2 compressor, condensing evaporator, reservoir, gas-liquid separator, filter dryer, pump, throttling device, evaporator, and expansion vessel, collectively crafting an exceptional cooling ensemble.
The The CO2 gas-liquid separator is pivotal in the CO2 compression refrigeration system, effectively isolating droplets from the evaporator to prevent compressor wet strokes, and maintaining a stable liquid level during pump operations. It also stores end-equipment liquid returns when pumps cease operation. As a reservoir, it accommodates all system CO2 liquid and features an auxiliary evaporator to prevent excessive CO2 pressure post-shutdown. In the NH3/CO2 cascade system, the condensing evaporator serves double duty, facilitating NH3-side evaporation and CO2-side condensation, achieving unmatched thermal efficiency.
2. Advantages of NH3/CO2 Cascade Refrigeration System: Uncover the unparalleled benefits that redefine industrial refrigeration.
(1) Reduced NH3 Unsafe Factors: Innovative safety measures that enhance operational security.
(1.(1)) The NH3/CO2 cascade system significantly diminishes NH3 charge pressure to approximately one-tenth of traditional ammonia systems, setting a new benchmark for safety and efficiency.
(1.(2)) NH3 is strategically confined to dedicated machine and equipment rooms, akin to a 'tiger in a cage,' under the watchful eye of expert personnel, ensuring maximum safety.
(1.(3)) Capitalizes on NH3's superior heat transfer properties in high-temperature regions, optimizing the cooling of CO2.
(2) CO2 as a medium is safely integrated into high-traffic areas such as operation rooms and warehouses, guaranteeing the utmost safety for personnel and assets.
