柳州市某工程要求室内参数夏季26±2℃,冬季18±2℃,相对湿度60±5％,风速0.5米/秒,若采用蒸汽加湿仅自动控制仪表一项就需投资1000多元,冬季三个月需蒸汽374吨,2300元左右,而且还有噪声和溴气。同样一个工程若先将需要的空气用加热器加热到18℃后喷水(循环水或柳江河水(12℃左右)至室内许可状态,则仅耗300多元。如冬夏都用地下水(18～22℃)等温加湿,则更节约能源。既使在最不利情况下利用加热器把空气加热到24℃,水温9℃时也
A project in Liuzhou city requires indoor parameters of 26±2°C in summer, 18±2°C in winter, 60±5% of relative humidity, and wind speed of 0.5m/s. If steam humidification is used, only automatic control of the instrument will require investment of more than 1,000 yuan. Month steam needs 374 tons, about 2300 yuan, but also noise and bromine. In the same project, if the required air is first heated to 18°C with a heater and water is sprayed (circulating water or Liujiang River water (about 12°C)) to an indoor permitting state, it will consume only 300 yuan. For example, use groundwater in winter and summer (18-22 °C) Isothermal humidification saves energy even when the heater is used to heat the air to 24°C in the most unfavorable case and the water temperature is 9°C.
