If the condensed water collected here is recycled for cooling of a stirring process of a lithium battery production factory or cooling of a component capacity process, the indoor temperature is about 24 ℃, the cooling water with higher temperature and the indoor heat exchange efficiency are lower at the moment, and when the condensed water is used as the cold water of an air conditioning system for water supply, the tail end needs a very large heat exchange area, so that the condensed water generated by the common ice water does not have a very high utilization value, and the condensed water generated by the air conditioning system at present does not have an explicit purpose and is generally directly discharged.

And a sewage discharge pipe 8 is arranged at the bottom of the first water collecting tank 1 and the second water collecting tank 2.
The method for recycling the low-temperature condensed water of the dehumidifier surface cooler comprises the following steps:
(1) Surface cooler condensate water in a surface cooler of a dehumidifier is primarily collected by a first water collecting tank 1 and then is conveyed to a second water collecting tank 2;
(2) The water level in the second water collecting tank 2 is controlled at a certain scale through the ball float valve 21, and the adjusting mode is as follows: when the water level in the second water collecting tank 2 is lower than a set value, a floating ball of the floating ball valve 21 descends, the valve is opened, and water in the first water collecting tank 1 flows into the second water collecting tank 2 until the water level reaches a designated scale;
