Optimization of heat pump drying fire hose with variable temperature strategy
As an important fire prevention and control tool,the maintenance of fire hose is particularly important.Timely drying of the hose can extend the service life of the hose and ensure that it is always in good working condition.To reduce the drying en-ergy consumption of fire hose and optimize the drying perfor-mance of heat pump,the heat pump drying treatment of fire hose is performed with variable temperature strategy.The effects of ini-tial drying temperature,moment of changing temperature,and variable temperature on the performance of heat pump(specific moisture extraction rate,moisture extraction rate,coefficient of performance)were analyzed by single factor test.Experiments were designed using the response surface method,the mathemati-cal model was fitted to the test data,and the reliability of the model was verified by variance analysis.The multi-objective joint solution of the regression equation was carried out,and the opti-mal process parameters of the heat pump variable temperature dry-ing fire hose were obtained as follows:initial drying temperature was 42.2℃,the moment of changing temperature was 80 min,and the variable temperature was 33.8℃.Parallel experiments show that the average error between the predicted value and the experimental value is 3.92％,indicating the high reliability of the model.
