Yu Nuo Cooling Xiaobian introduces the precautions for using closed cooling towers in winter. The products of Jiangsu Yunuo Cooling Technology Co., Ltd. are used to the needs of different media, different temperatures, different specific heat, different particle content and different operating environments by the diversity of materials, the variability of structure and the multiple options of
the way.
(1) In order to better avoid the freezing of air conditioning copper pipes and spreading water, we must pay attention to the following aspects:
(2) Add freeze-free liquid to the circulating system water of the sealed cooling tower, or add auxiliary cold-proof electric water heater in the pipeline; Can avoid the cold cleaning of cooling circulating water.
(3) After adding freeze-free liquid to the cooling circulating water in the closed cooling tower, the freezing cleaning temperature drops and it is not easy to freeze clean. The higher the concentration value of the antifreeze, the lower the freezing temperature, but the heat conductivity will decrease. Therefore, we should pay attention to the selection of closed cooling tower; If there is water seepage, fill the water when the dilution does not freeze, and make the temperature of the freezing clean.
(4) When the circulating pump of the sealed cooling tower is operating, the cold proof electric water heater is heated, so the water is not easy to freeze clean. If there is a place where the circulating pump stops, it is necessary to assist the circulating pump in addition, and it is proposed to use a full set of cold protection device.
(5) The water circulation system of the sealed cooling tower is planned for the gate valve in position 3. In the place where the cooling circulating water operates the volume according to the bypass valve tube, if the total flow rate of the bypass valve tube is increased, the flow speed in the copper pipe of the air conditioning will be reduced, and it may be frozen clean even if there is a load. Please adjust the water flow rate of the small circulation system of the FRP cooling tower.
(6) closed cooling tower In order to better avoid the freezing of watering centrifugal pump and watering pipeline, please use cold-proof electric water heater to maintain the temperature of the stainless steel sink below.
The above is Jiangsu Yunuo Cooling Technology Co., Ltd. to introduce you to the use of closed cooling tower in winter what are the precautions for all content, if you have any questions, please feel free to consult.
