串联系统是一种在冰箱/冷冻柜系统中使用两个蒸发器的新方法。该系统配置有两个串联的蒸发器和适当的控制装置，利用瞬态运行来节约能源。该系统已应用于商业18 ft3（509.7 L）机组和采用厚保温节能阀的高效取样机组。与基准机组相比，两台机组的日能耗均降低了18%。此外，还介绍了一种新的不使用电阻加热器的除霜方法，并进行了试验。 这种“内部除霜方法”利用两个蒸发器之间的热虹吸现象，显示出比传统方法优越的潜在特性。利用控制技术，串联系统允许对每个隔间进行独立的温度控制。最后，性能测试表明，串联系统在非常不同的操作条件下可靠运行。关键词:1995年，冰箱，冷冻柜，能耗，节能，瞬态，运行，循环，热流，实验，制冷，除冰，测试，热虹吸，蒸发器，性能，温度控制引用: 研讨会，ASHRAE Trans。1995年，第101卷，第2部分

The Tandem System, a new approach for using two evaporators in a refrigerator/freezer system, has been developed. The system configuration, with two evaporators connected in series and appropriate controls, takes advantage of the transient operation to save energy. This system was applied to a commercial 18 ft3 (509.7 L) unit and a high-efficiency sample unit in which the thick insulation and energy-saving valve were used. The daily energy consumption for both units were reduced by 18% as compared to the baseline unit. In addition, a new defrost method without using an electrical resistance heater was introduced, and the test was performed experimentally. This "internal defrost method," using the thermosiphon phenomenon between two evaporators, showed the potential of superior characteristics over the conventional approach. Taking advantage of control techniques, the Tandem System allowed independent temperature control for each compartment. Finally, a capability test showed that the Tandem System operated reliably at very different operating conditions.KEYWORDS: year 1995, refrigerators, freezers, energy consumption, energy conservation, transient, operations, cyclic, heat flow, experiment, refrigeration, deicing, testing, thermosiphon, evaporators, properties, temperature control
