摘要

针对目前家用净水机需要频繁清洗和更换滤芯的问题，本文提出并搭建了一种利用半导体珀尔贴效应和空气增湿去湿原理相结合的家用净水系统，实验研究了循环风量对系统运行工况、功耗、单位时间产水量和单位能耗产水量的影响。实验结果表明：随着循环风量的增加，半导体冷热端温度逐渐下降，冷热端温差略有下降，系统制冷量、半导体功耗和制冷性能系数(COP)逐渐上升。当循环风量为100 m3/h，单位时间产水量和单位能耗产水量达到峰值，分别为345 g/h、459 g/(kW?h)。系统所制取水的卫生指标(TDS＜3 mg/L)符合国家饮用水标准，系统日产水量(＞7.2 L/d)满足一般家庭饮水需求。

Abstract

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.
