在水利水电建设工程中,通常有两种用途的制冷厂:一种制冷厂的冷量用于混凝土预冷;另一种制冷厂的冷量用于大坝混凝土冷却(后冷)。水文对用于混凝土预冷的制冷厂设计作一介绍。 1 制冷厂设计中应掌握的资料为了确定制冷厂规模,应掌握下列资料: a.干球温度; b.湿球温度; c.当地水温; d.夏季高峰月的小时、日和周浇筑强度; In water conservancy and hydropower construction projects, there are usually two types of refrigeration plants: one refrigeration plant is used for concrete precooling; the other refrigeration plant is used for dam concrete cooling (post-cooling). Hydrology introduces the design of a refrigeration plant for pre-cooling concrete. 1 Materials to be mastered in the design of refrigeration plants In order to determine the scale of a refrigeration plant, the following materials should be mastered: a. Dry-bulb temperature; b. Wet-bulb temperature; c. Local water temperature; d. Hourly, daily and weekly pouring strength of summer peak months ;
