摘　　要：在既有光伏组件的基础上,安装集热背板形成分体式PVT组件,搭建分体式PVT热泵系统试验台,在晴天和多云典型日2种工况下进行系统运行性能试验,将水箱内的水从常温加热到60℃。试验结果表明,在晴天和多云典型日下,系统平均COP分别为4.11和4.20,均高于相同工况下的空气源热泵;最大发电效率分别为13.2%和19.9%,PVT组件表面温度分布均低于40℃,有明显的降温提效作用;平均得热因子分别为48%和71%,无量纲压力损失系数保持在0.030~0.047,均流性较好。Based on existing photovoltaic modules,the combined PVT modules were formed by installing heat collectors,and an experimental setup of combined PVT heat pump system was established.The system operation performance experiments were conducted under two working conditions of sunny and cloudy typical days,and the water in the water tank was heated from the ambient temperature to 60°C.Results show that the average coefficient of performance of the system are 4.11 and 4.20 under the typical sunny and cloudy working conditions,respectively,which are higher than air-source heat pumps under the same working conditions.Correspondingly,the maximum power generation efficiencies are 13.2%and 19.9%,respectively.The surface temperature of PVT modules is lower than 40°C,which reveals apparent surface cooling and efficiency improvement effects.The average heat acquisition factors are 48%and 71%for the sunny and cloudy typical days,respectively.The dimensionless pressure loss coefficient is maintained in the range of 0.030-0.047,which indicates that the flow is well uniform.
