| According to the weather information of Tianjin, the paper points to the characteristics of air source and solar energy.A dual source heat pump system-solar energy/air compound source heat pump system is puted forward by Tian jin Institute of Urban Construction.The compound source heat pump has two parallel condensers under refrigerating condition and two parallel evaporators under heating condition.The paper researches the peformance of the compound heat pump in summer.In the analysis of the compound heat pump system, the paper is divided into two parts.One part is the simulation and another is the testing.In the simulation,the paper estabishes the mathematical modal of the heat pump system,and the program is established by Visual Basic language.In the experiment,with the results of the trend of system refrigerating capacity, power consumption and COP of system thourgh testing two operation modes under different testing situation.The paper analysises the experimental results.Finally,the paper carrys out comparative analysis on the theoretical and experimental results and states the reason of error.The SEER of two modes are calculationed,the results indicate that dual source heat pump system is better than that of the air source heat pump system in general and the SEER increases to 18.01%.
