Experimental study on refrigeration performance of new cabinet semiconductor air conditioning
摘要
Abstract
An integrated semiconductor air conditioner for electrical cabinet is designed,and the effects of input current(6~11 A),ambient temperature(20~35℃),temperature difference between inside and outside the cabinet(0~40℃)and air volume at the hot end on the refrigeration performance of the cabinet semiconductor air conditioner are studied by using the calibrated room calorimeter method.The experimental results indicate that when the ambient temperature is 26℃and the temperature difference between the inside and outside of the box is 20℃,the optimal working current of the semiconductor air conditioner is 8 A(36 V),and the refrigeration capacity is the largest(213 W).When the current is 8 A(36 V),with the increase of ambient temperature(20~35℃),the cooling capacity and COP increase by 13.9%and 11.9%,respectively.With the increase of temperature difference(0~40℃)inside and outside the box,the refrigeration capacity and COP both increase significantly(108~340 W,0.38~1.21),and the increase of heat exchange capacity is the main reason for the increase of refrigeration capacity.When the air volume of the hot-end fan is increased from 108.63 m3/h to 156 m3/h,the cooling capacity increased by 4.02%and the COP increased by 1.50%.It can provide reference for the design optimization of new cabinet semiconductor air conditioning.关键词
