| Abstract: | The air temperature and relative humidity at the dryer outlet can be increased in an inner-heating heat pump dryer,so the air can absorb more water vapor from materials to be dried.The structures and working principle of inner-heating heat pump dryer are introduced,and the SMER equation is given.Based on the equation,the influences of air temperature at the dryer inlet,air temperature and relative humidity at the dryer outlet,air temperature at the evaporator outlet on SMER are calculated and analyzed. |
