摘　　要：以燃气热泵干燥装置为研究对象,建立其干燥数学模型,分析了不同干燥空气温度条件下,燃气热泵干燥装置的COP,SMER,除湿费用和CO2排放量的变化情况,并与电动热泵干燥装置进行了比较。研究表明,燃气热泵干燥装置在高温干燥时的SMER比电动热泵干燥装置高65%,除湿费用和CO2排放量分别只有电动热泵干燥装置的60%和17%,具有更好的经济性能和环保性能。The drying mathematical model of a gas heat pump dryer was made. The coefficient of performance （COP） , specific moisture extraction rate （SMER）, moisture extraction cost and CO2 emission of the gas heat pump dyer were cal- culated under conditions of different drying air temperature levels. The calculation results were compared with the electric heat pump dryer. Results show that the gas heat pump dryer is energy efficient and environmentally friendly with 65% higher in SMER, 60% and 17% lower in moisture extraction cost and CO2 emission, respectively.
