项目摘要

For the purpose of development of condenser for heat-pump systems, experiments were carried out on heat-transfer and pressure loss characteristics of low pressure loss fluidized bed heat exchanger with an extremely small static bed height of glass beads. This heatg exchangerf was composed of of a bare tube.bank in staggered arrangement and a multi-slit distributor designed sepcially to reduce tghe pressure loss. The effect of the cross-sectional shape of the distributor, the particle size of the glass beads, the static bed height, and the number of rows on heat transfer performance were examined. The heat transfer and pressure loss character- istics are compared with existing experimental data, considering the fan power and the compact- ness of the heat exchanger. On the basis of the above-mentioned data, a practical fluidized- bed condenser was designed and developed; then, the performance of the condenser was measured. Through this project, the practical usefulness of the present fluidized bed heat exchanger has been clarified
为了开发用于热泵系统的冷凝器,对低压损失流化床热交换器的热量转移和压力损失特性进行了实验。该Heatg Exchangerf由裸露的管子组成。交错的布置和一个多缝分配器,以降低TGHE压力损失。检查了分配器的横截面形状的影响,玻璃珠的粒径,静态床高度以及热传递性能的行数。考虑到热交换器的风扇功率和紧凑型,将传热和压力损失特征与现有的实验数据进行了比较。在上述数据的基础上,设计和开发了实用的流化床冷凝器。然后,测量冷凝器的性能。通过这个项目,已经澄清了当前流化床热交换器的实际实用性
