摘要:
为解决岗亭空调占地及冬季空气源热泵适应低温环境差的问题,提出一种在外壁面涂有太阳能选择性吸收材料的亭壁蒸发器,以吸收太阳能和室内外空气的热量的策略.应用制冷系统热动力学的理论,建立亭壁蒸发器数学模型,提出复合对流换热系数的概念.基于Matlab软件对亭壁蒸发器建立仿真程序,进行实验验证,并分析太阳能辐射照度、环境温度及结构参数对亭壁蒸发器运行状况的影响.研究结果表明:该模型能有效预测亭壁蒸发器的运行工况;太阳辐射照度对亭壁蒸发器的影响最大.
Abstract:
In order to solve the problems of air conditioning occupied by post and air source heat pump in winter, the pavilion wall evaporator coated with solar selective absorbing material on the outer wall surface is proposed, which can absorb the heat of solar energy and indoor and outdoor air.By applying the thermodynamics theory of refrigeration system, a mathematical model of the kiosk evaporator is established, and the concept of composite convection heat transfer coefficient is proposed. Furthermore, a simulation program is established based on matlab for the kiosk evaporator, and the experimental verification is conducted to study the effect of solar radiation illumination, ambient temperature, and structure parameters on the operating conditions of the kiosk wall evaporator. The research shows that this model can predict the operating conditions of the kiosk wall evaporator effectively, and the solar radiation illumination has the greatest impact on the kiosk wall evaporator.
