摘　　要：为了研究环保工质R32的直膨式太阳能热泵运行特性,设计并搭建了一个实验平台,该平台将用于本科生和研究生的实验教学。该平台主要由太阳能集热/蒸发器、压缩机、冷凝器/蓄热水箱、电子膨胀阀和数据采集与控制系统组成。其中,数据采集与控制系统采用了组态王(KingView 6.55)软件,实现了平台的运行控制以及数据的采集、处理、存储和显示。测试结果表明:平台运行安全可靠,各项参数测量快速准确,制热输出性能稳定,并且具有高集热效率和制热效率。在平均太阳辐射强度为734.4 W/m^(2)、平均环境温度为18.1℃的条件下,该平台能将0.2 m^(3)的水从12.1℃加热至55℃,平均制热系数高达4.3。该实验平台为实现低碳清洁供热提供了一个有效方案,可以开展多个设计性和研究性实验项目,有助于激发学生的学习兴趣和学术追求,培养他们的科学研究素养和创新能力。In order to study the actual operation characteristics of a direct-expansion solar-assisted heat pump(DX-SAHP)system by using R32 as refrigerant,an experimental platform is designed and built,and is used to undergraduate and postgraduate experimental teaching.The platform mainly comprises a solar collector/evaporator,a constant-frequency compressor,a heat storage water tank surrounded by a winding condenser,an electronic expansion valve,and a data acquisition and control system.Among them,the data acquisition and control system is based on KingView 6.55 software,which can realize platform control,and the collection,processing,storage and display of data.Test results show that the platform has the advantages of safe and reliable operation,rapid and accurate parameter measurement,stable heating output performance,and high collector efficiency as well as heating efficiency.When the 0.2 m^3 water at 12.1°C is heated to 55°C with average solar radiation intensity of 734.4 W/m^2 and average ambient temperature of 18.1°C,the average heating COP reaches 4.3.The experimental platform provides an effective solution to the low-carbon and clean heating,by which multiple design and research experiments can be carried out.It may be very useful to arouse students'learning interest and academic inclination,and cultivate students'scientific research ability and innovative spirit.
