Author：Trlon Views: Time:2021-11-04

　　1. The main technical parameters and equipment quantity of the low-noise square cross-flow cooling tower are shown in the equipment table of the construction drawing.

　　The role of the cooling tower is: the waste heat generated in the industrial production or refrigeration process is generally taken away through the cooling water. The role of the cooling tower is to exchange heat between the cooling water carrying the waste heat and the air in the tower, so that the waste heat is transferred to the air and dispersed into the atmosphere. Mainly used in air conditioning cooling systems, refrigeration series, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and other fields. It is mostly used in air conditioning cooling, freezing, and plastic chemical industries.

　　1. Low-noise square cross-flow cooling tower, the main technical parameters of the equipment.

　　1: Inlet water temperature (t1)-refers to the temperature of the circulating water at the entrance of the cooling tower. The national standard requires 37.

　　2: Outlet water temperature (T2)-refers to the circulating water temperature at the outlet (or bottom basin) of the cooling tower, and the national standard requires 32.

　　3: Water temperature drop (t)-refers to the temperature difference between the inlet and outlet circulating water of the cooling tower, which is required by the national standard 5.

　　4: Wet bulb temperature (TWB)-refers to the amount of water vapor in the air. Usually, the wet bulb temperature is measured by relative humidity, which reflects how close the air is to saturation. When the relative humidity is equal to 1, the air is saturated. When the relative humidity is less than 1, the air is dry and the moisture is easy to evaporate. When the relative humidity is equal to zero, it means that there is no water vapor in the air. The relative humidity in the northwest is relatively low and the air is relatively dry, while the relative humidity and air in the southeast coastal areas are relatively high. The national standard is 28 (about 75% relative humidity), if it is 27, the relative humidity is about 70%.

　　5: Dry bulb temperature (TDB)-the air temperature, the national standard requires 31.5.

　　6: Cooling width (△T)---refers to the difference between the temperature of the circulating water at the outlet of the cooling tower and the temperature of the wet bulb. The larger the cooling range, the better the heat dissipation effect of the cooling tower, and vice versa.

　　7: Atmospheric pressure (P0)-refers to the pressure generated by the air on the earth, a standard atmospheric pressure is 1.013×105Pa,

　　2. The composition range of the cooling tower:

　　Each cooling tower shall include a tower, a supporting frame, a damping device, a steel casing, a fan drive system, an external air deflector, and a fan vibration cut-off switch. Inlet windows, splash baffles, water receivers, fillers, hot water distribution systems, cold water collection trays and filters, inspection doors, automatic water replenishment devices, overflow and drain outlets of submerged water trays, electric heaters and supporting facilities The chassis water temperature and water level controller. Provide, water inlet interface. The national standard flange and the balance connecting pipe interface between the tower tube and the oil injection port are reserved.

　　3. Cooling tower: technical performance requirements for main components.

　　1. Cooling tower properties:

　　The supporting cooling tower should meet the long-term operation needs of the air conditioning system, strictly meet the needs of continuous operation all-weather, and meet the refrigeration and heat exchange needs of the refrigerator under the design outdoor wet bulb temperature conditions to ensure that the refrigeration system can be normal and efficient under any conditions under the design conditions , Reliable operation. The key materials that are immersed in water for a long time include loose water fillings. The water collecting tray, hot water pan and water distribution system should ensure the corrosion resistance and durability required for long-term operation.

　　2. Cooling tower motor:

　　The fan motor adopts a fully enclosed, three-phase squirrel-cage cooling tower special motor, double waterproof vapor seal, the motor protection level is not less than IP55, insulation level f, and temperature rise level B.

　　3. Cooling tower fan:

　　The fan should be a high-performance axial flow fan with aluminum alloy impellers, equipped with an outlet duct, and must be an external duct to ensure ventilation efficiency. The top is equipped with a protective cover to prevent foreign matter from entering the tower, and it should be a low-noise fan.

　　4. Cooling tower bearings:

　　The fan and steel shaft are supported by ball bearings, with heavy-duty self-calibration, moisture-proof seal and integral ring housing.

　　5. Fan drive:

　　Belt drive is used. The drive belt is not allowed to adopt multiple split forms, and should be a single-piece multi-slot conjoined belt. The belt material is a high-strength neoprene polyester material with built-in reinforcing materials, which has the ability to resist aging and water corrosion.

　　The above is the introduction of the square cross-flow low-noise cooling tower brought by the cooling tower manufacturer Teling Air Conditioning. If you have more cooling tower holiday needs, you can continue to pay attention to us.
