据悉,全国现有各中小企业冷却塔约二万余台,年用电量2.3亿度,相等于一台五万千瓩机组一年的发电量。其中上海就有五千台,约占全国的1/4。由于这些设备老、旧、质差、多数冷却塔与风机不匹配,因此冷却效果低,飘水严重、噪声高,耗电大。据测试,全市一年要多耗六千万度电,相等于该市一天的用电量。上海市计划用电办公室,为此在日前召 It is reported that there are about 20,000 cooling towers for SMEs in the country, and the annual electricity consumption is 230 million kWh, equivalent to a year’s power generation of a 50,000-millimeter unit. Shanghai has 5,000 of them, accounting for about one-fourth of the country. Because these equipments are old, old, poor quality, and most cooling towers do not match the fans, they have low cooling effect, serious floating water, high noise, and large power consumption. According to tests, the city consumes more than 60 million kilowatts of electricity a year, which is equivalent to the city’s electricity consumption for one day. Shanghai plans to use electricity for this purpose.
