Overview "cooling tower" refers to a device may be water-cooled. Water flowing through the air with the heat exchange and mass transfer, causing the temperature drop. Open cooling towers is the use of contact with water and air, dispersed by evaporation to an apparatus or an industrial refrigeration and air conditioning of waste heat generated. The basic principle is: after drying (low enthalpy) of air through the fan twitch from the inlet into the cooling tower at the net; the saturated vapor pressure of water molecules to large high-temperature low-pressure air flow, heat (high enthalpy) The water from the broadcast tower has been spilled into the water system. When the water droplets and air in contact, on the one hand due to the direct heat transfer contact with water in the air, on the other hand due to the presence of water vapor pressure difference between the surface and the air, is evaporated under the pressure of the phenomenon, i.e., by dry air with an unsaturated heat transfer away sensible heat of water, some water evaporation latent tropical water to go, so as to achieve the cooling water to cool the head. Closed cooling tower is the use of water and coil contact, passing away in the heat exchanger coil cooling refrigerant heat for cooling purposes through the wall of heat. Closed cooling tower circulating water in the cooling tower and air circulating inside the heat exchanger cooling coil away just before contact with the working fluid within the heat pipe and plate, fill pipes appropriate pay, compared to open cooling towers, closed cooling tower most obvious feature is the increase in coil needs to be cooled liquid refrigerant flow is not in direct contact with the water in a steel coil, heat transfer through the wall. Features 1, because no filler, 塔内基 in the hollow of the state, small wind resistance, low noise. 2, using our patented technology to produce high-efficiency water collection device, effectively reducing the drift of water, water-saving effect is obvious. 3, the tower body with streamlined design, with a small gap between fan and duct, resulting in a large amount of wind, wind speed faster, better cooling effect. 4, automatic rotary atomizer using polymer wear-resistant materials, corrosion resistance and long service life. 5, modular design, easy to transport, installation and commissioning. 6, no plug, no maintenance, stable and reliable. Complete elimination of the packed column clogging due to impurities in the circulating water filler and filler aging, deformation, rattle, cloth and wash-down water nozzle clogging, packing debris clogging pipes, pumps and heat exchangers, such as a series of towers and process systems affect device performance phenomenon. Eliminate frequent cleaning, replace the packing and distribution of water sprinklers trouble. Please provide the following custom parameters: 1. Specifications Model (LWH); 2. The pipe wall thickness; 3. transport medium (what kind of resin); 4. color.
