日本石川岛播磨重工业株式会社,最近以大、中型凉水塔(处理能力每小时2000吨以上)风机节省动力为目标,开发和研制成功了微型计算机自动控制系统。目前,凉水塔风机普遍采用的操作控制方法是,根据气温变化读出冷却水的出口温度,然后通过手动来操作控制需运转风机的台数和时间,以使冷却水温度达到规定值。风机的起动和停运,也都全靠手动操作。这种操作方法,比起那些完全不进行操作控制的凉水塔风机来,可以节省动力消耗30％。
Japan Ishikawajima Broadcast Grinding Heavy Industry Co., Ltd. recently, large and medium-sized cooling towers (processing capacity of more than 2,000 tons per hour) fans to save power as the goal, the development and development of a microcomputer automatic control system. At present, the cooling tower fan commonly used method of operation control is based on temperature changes read the outlet temperature of cooling water, and then manually control the number and time required to run the fan to make the cooling water temperature reaches the specified value. Fan start and stop operations, but also rely entirely on manual operation. This method of operation, compared to those who do not operate the cooling tower fan, you can save power consumption by 30%.
