主动式冷梁热工性能仿真模型及实验验证

以无限空间射流理论和表冷器换热理论为基础，对主动式冷梁的工作原理进行了分析。在假设条件下，建立了诱导送风模型和干工况表冷器换热模型。结合这两种模型，最终建立了主动式冷梁工作模型。在设定的5种静压箱静压值下，对主动式冷梁样品的一次风量、二次风量、水侧换热量等热工参数进行测试。选取诱导比和制冷量两个表征冷梁性能的参数作为标准，对模型理论值与样品实际值进行了一致性与差异性分析，验证了所构建的主动式冷梁模型。

Simulation model of active chilled beams thermal performance and experimental verification

The working principle of active chilled beams (ACBs) was analyzed on the basis of unlimited space jet theory and cooler heat exchanger theory. Inducement ventilation model and cooler heat exchanger model were built under the assumptions. The two models were combined to establish ACBs model. Primary air volume, secondary air volume, water side heat transfer amount etc were measured in five specified static pressure value. Induction ratio and refrigerating capacity were selected as two standards of ACBs performance parameters. The results of the consistency and differences of theoretical value with practical value verified the established model.
