产品特点：
1)正常情况 冷却塔下的水温降不下来
在进行冷却塔的设计时，所采用的气象参数，如干、湿球温度等，是按照一定的保证率来选择的，一般是以每年可以超过10天或5天的气象参数作为依据，也就是平均一年中要有10天或5天的温度比设计时所选取的温度高，此时水的温降将达不到设计要求。这样选取气象参数的目的主要是考虑经济问题。因为温度是靠多年统计积累的气象资料确定的，如果选用*高温度，由于出现的天数很短，这样设计出的冷却塔可能将很不经济。另外，设计时所选用的是日平均温度，它是每天2时、8时、14时、20时四次测取温度的平均值，比一天中的*高温度要低，这就是有时短期出现水温降不下来的原因，这种现象属于正常情况。在这种情况下，若使用地下水作补充水时，由于地下水的温度较低，可以适当多加一些地下水，使混合后的水温达到使用要求。
1) under normal circumstances, the water temperature of the cooling tower does not fall down
In the design of cooling tower, meteorological parameters used, such as dry and wet bulb temperature, according to certain guarantee rate to choose the general meteorological parameters per year can be more than 10 days or 5 days as the basis, which is an average of about 10 days a year or 5 days of temperature than the design selected the high temperature, the temperature drop of water can not meet the design requirements. So the purpose of selecting the meteorological parameters is mainly to consider the economic problems. Because the temperature is determined by the meteorological data accumulated over the years, if the maximum temperature, the number of days due to the emergence of a very short, so the design of the cooling tower may not be economical. In addition, the design is the average temperature, it is a daily average of 2, 8, 14, 20 and four times of measuring temperature, lower than the highest temperature during the day, this is sometimes short causes temperature drop down, this phenomenon is normal. In this case, if the use of groundwater as a supplementary water, due to the low temperature of groundwater, can be appropri |
