近年来，液体干燥剂在常规空间空调中的应用受到了广泛关注。最先进的家用液体干燥剂除湿器使用平行板横流调节器换热器，从室内空气中去除潜在负荷，并通过蒸发冷却将吸收热排出室外气流。开发了一个数值模型来评估改进的逆流调节器设计，它可能提供显著的性能和成本优势。 分析表明，调节器的性能仅取决于两个无量纲参数，即雷诺数和L/D（板长与间距之比）。创建了有效性、容量和运营成本图，构成了逆流设计的充分标准。讨论了模型的分析、发展和结果。关键词:除湿器，吸收式除湿器，干燥剂，性能，计算，空间冷却，错流换热器，蒸发冷却，雷诺数。 引文:研讨会，ASHRAE交易，第97卷，Pt。1991年，纽约

The application of liquid desiccants to conventional space conditioning has received a substantial amount of attention in recent years. The state-of-the-art residential liquid desiccant dehumidifier uses a parallel-plate cross-flow conditioner heat exchanger where latent load is removed from the indoor air and the heat of absorption is rejected to an outdoor airstream through evaporative cooling. A numerical model was developed to evaluate an improved counterflow conditioner design, which may offer significant performance and cost advantages. The analysis demonstrated that the conditioner's performance depends on only two dimensionless parameters, the Reynolds number and the L/D (plate length over spacing) ratio. Effectiveness, capacity, and operating cost maps were created, which constitute sufficient criteria for a counterflow design. The analysis, development, and results of the model are discussed.KEYWORDS: dehumidifiers, absorbtion dehumidifiers, desiccants, performance, calculating, space cooling, cross flow heat exchangers, evaporative cooling, Reynolds numbers.
