Cooling in Hebei Equipment Co. countercurrent tower main features: 1, the water in the tower fillers, water top-down, bottom-up air, the two opposite flows of cooling towers. 2, good thermal performance counterflow cooling towers, three cooling sections: ① water distribution to filling the top of the space, the higher the temperature of this paragraph, so still heat to the air. ② packing water and air heat exchange section. ③ filler to a sump space segment watering, water is cooled in this section referred to as "tail effect." In the north of the temperature can drop 1-2 ℃. In summary, the countercurrent tower than crossflow towers in the same situation, small packing volume is about 20% higher countercurrent heat exchange tower more reasonable cooling efficiency. 3, clogging water distribution system, water spray to keep clean and not aging filler, reflux little moisture, frost and ice action easier. Multiple designs can be combined winter temperature in the desired amount of water can be combined with a single operation or closed for all fans. 4, construction installation and maintenance easy, low-cost, commonly used in air conditioning and industrial large and medium-sized cooling circulating water. Crossflow Tate points: l, water tower packing, the water from top to bottom, the horizontal flow of air from the tower to flow in a vertical tower two orthogonal A cooling tower. Commonly used in noise demanding residential area, it is air-conditioning sector to use more cooling cycle tower. Advantages: energy saving, low water pressure, wind resistance, also configure the low-speed motor, no dripping noise and wind noise moving, packing and distribution convenient water system overhaul. 2, free to build a foundation with the shape of the building more than one place, respectively, to start single or multiple cooling tower according to the desired temperature. 3, should be noted: a frame to 40% more heat exchange to have more volume filler, filler easy to aging, easy to plug the hole with water, anti-icing is bad, great moisture reflux. Advantages of crossflow towers is the tower countercurrent shortcomings.
