摘要: In this study, a simulated model of a heat-pump clothes-dryer system using a transient method was developed. Geometrical variations of the condenser and evaporator have been taken into account. The model was validated by experimental results in published literature. The fundamental phenomena during the drying process and the effects of the air volume on the drying process are reported. Both air and refrigerant cycles were examined in detail. Thermodynamic parameters of the dryer system in drying process, including the relative humidity, temperatures of the clothes and the air, the drying rate, the operating pressure including discharge and suction pressure, the system performance parameters, COP and SMER change over time, were carefully examined by using simulation results. It is found that when the circulating air volume increases, both the COP and SMER increase and the drying time decreases. It is also found that when the sizes of the condenser and evaporator increase, the drying time decreases and the SMER increases.
