摘要
本文论述了CO2双级系统在超市应用中各种运行工况和相应的运行特性,也论及不同负荷和运行工况下的主要原则和挑战。另外,分析了小型双级制冷系统中模拟和测量的运行结果,以帮助系统设计人员建模并避免可能存在的问题。
This paper explains and discusses various operating conditions and the resulting behavior of C02 booster systems in supermarket applications. It touches upon the main criteria and challenges relating to the different operating and load conditions. In addition to this, it considers and assesses simulated and measured operating results in a small booster refrigeration system so that system designers can model and avoid potential issues.
