| Abstract: |
| In order to verify thermoelectric refrigerator’s capability to be used as domestic dehumidifier, a typical single-stage thermoelectric dehumidification system was built by using a thermoelectric refrigerator. The moist air flowed through the cold side and the hot side in turn which condensed in the cold side and the heat dissipation was recycled in the hot side. The factors (voltage, temperature, mass flow rate etc.) which affect the thermoelectric dehumidification capacity and efficiency are analyzed. In addition, by conducting the experiment, the performance of this thermoelectric dehumidifier was optimally improved. For example, a test was carried out at atmospheric conditions of 26 ℃ and 65% humidity，the maximum amount of dehumidification of this device can reach 150 g/h, dehumidification efficiency can reach 0.37. |
