| Summary: | Considering the problem of frequent cleaning and replacement of filter elements for household water purifiers, a new household pure water production system based on the semiconductor Peltier effect and the principle of air humidification and dehumidification was proposed and established. The effects of circulating air flow rateon the system operation conditions, power consumption, water production rate, and water production per unit power consumptionwere experimentally studied. The results showed that with the increase incirculating air flow rate, the temperatures at the hot and cold sides of the semiconductors all decreased, the temperature difference between the hot and cold sides decreased slightly, and the cooling capacity of the system, semiconductor power consumption, and coefficient of performance all increased. When the circulating air flow ratewas 100 m3/h, the water production rate and water production per unit power consumption reached maximum values of 345 g/h and 459 g/(kW?h), respectively. The total dissolved solids (TDS) hygienic indicator was <3 mg/L and the daily water production of the system was >7.2 L/d, thus meeting the drinking water needs of general households. |
