In this study

a cabinet semiconductor cooling device was designed and its refrigerating capacity and cooling efficiency were tested using a test platform. The performance parameters were obtained according to test-based analyses of the refrigerating capacity

cooling efficiency

and other factors. According to the test results

for an average indoor temperature of 26 ℃ and 200-360 W input power

the cooling efficiency first increases and then decreases

reaching a maximum value of 69.5% when the input power is 232 W. Meanwhile

the average amount of refrigeration throughout the test is 455.46 kJ and the power of the semiconductor cooling device is 151.8 W

which can remove 3.04% of the energy in a 5 kW communication cabinet.
