Abstract：The enclosure structure of the barn is an important factor affecting the energy consumption of the barn.Through the evaluation and analysis of the performance of the enclosure structure of the barn,the enclosure structure of the barn can be reasonably improved and the energy consumption can be reduced.Based on no-load experiment,a lumped parameter model(RC model)based on thermal resistance-heat capacity network is proposed.Through the reverse parameter identification,the variation rules of the related parameters such as heat capacity,thermal resistance and osmotic load were given,and the load verification experiment and the evaluation and analysis of the enclosure structure were further carried out.The results show that the RC model can be used as an evaluation model,in which Qinf parameter identified by the model has a certain positive correlation with the unit water evaporation power consumption of the grill,and the larger Qinf parameter is,the larger unit water evaporation power consumption is.This method can provide a reference for evaluating the performance of the enclosure structure of heat pump oven.
