The cooling tower should be installed on the roof or on the ground of a building with sufficient carrying capacity. It is required to be well ventilated. The shortest interval between the air inlet of the cooling tower and the building parallel to the outer diameter of the tower should not be less than 1.5 times of the outer diameter of the tower to meet the requirement of fresh air entering the tower unimpeded. The cooling tower should not be installed in a high wall with waterproof channel and no air circulation.

Technical knowledge of closed cooling tower units.
1. The foundation should be horizontal and not skewed, and the center line of the cooling tower is perpendicular to the horizontal plane, otherwise it will affect the motor operation.
2. Because the tower body cannot accept the water pipe component, it is necessary to set up another pillar when setting up the water pipe. The water outlet pipe over 10mm should be connected with an anti-vibration hose (high-pressure hose). When setting up the chassis, the installation personnel should step on the reinforcing ribs of the chassis to prevent damage to the chassis. When setting up the chassis shell chassis and other fiber parts, screws should be put on first, and then tightened sequentially to prevent the shell chassis chassis deformation, and after the joint and the surrounding dry, can be in the joint laying fiber wool and altered resin, to prevent the tower leakage.
3. The electric fan of the cooling tower of the cooling tower shall rotate clockwise with the wind direction upward (or outward). The gap between the blade tip of the fan and the inner wall of the tower shall be uniform. Check whether the viewpoint of the blade device is the same, whether the debugging work is balanced, whether the power supply is the same as the rated power. The motor shall be wired according to the marked wiring direction. The junction box shall be sealed after wiring. The motor circuit shall be provided with phase missing operation maintenance and overload operation maintenance, to ensure the reliable operation of the motor.
The waste heat generated in the process of industrial production or refrigeration is generally guided away by cooling water. A certain amount of water is absorbed from natural water bodies such as rivers, lakes and seas as cooling water. The cooling process equipment absorbs waste heat to raise the water temperature and then discharges it into rivers, rivers, lakes and seas. This cooling method is called DC cooling. When DC cooling conditions are not available, cooling towers are required for cooling.
The role of the cooling tower is to carry out heat exchange between the cooling water with waste heat in the tower and the air, so that the waste heat is transferred to the air and the air is dispersed.

Classification of cooling towers.
A, according to the ventilation mode, there are: natural ventilation cooling tower cooling tower, mechanical ventilation cooling tower, mixed ventilation cooling tower.
B, according to the contact mode of hot water and air, according to the contact mode of hot water and air, there are: wet cooling tower, dry cooling tower, dry and wet cooling tower.
C, according to the flow direction of hot water and air, according to the flow direction of hot water and air, there are: counterflow cooling tower, cross flow (AC) cooling tower, mixed flow cooling tower.
D, other types of cooling towers other types include jet cooling towers and cooling towers cooled by rotary table lifting water. the working principle of cooling towers cooling towers is a kind of equipment that uses the contact of water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation. the basic principle of its work is: dry (low enthalpy) air enters the cooling tower from the air inlet network after being pumped by a fan, high-temperature water molecules with large saturated steam partial pressure flow to the air with low pressure, and the water self-spreading system with damp heat (high enthalpy value) is sprayed into the tower. When water droplets contact with air, on the one hand, due to the direct heat transfer between air and water, on the other hand, due to the pressure difference between the surface of water vapor and air, the cooling tower generates evaporation phenomenon under the action of pressure, taking away the heat in the water, that is evaporation heat, in order to achieve the purpose of cooling, but the influence of the water temperature change of the tower on the refrigeration unit. For the mechanical cooling tower, the higher the fan speed, the lower the cooling water temperature, the lower the power consumption of the cooling tower at this time. However, for the main engine, the lower the cooling water temperature, the lower the cooling water temperature, the lower the power consumption of the cooling tower, but for the main engine, as the water temperature into the condenser rises, the corresponding host power consumption will increase.
Under various outdoor meteorological conditions and different loads of the main engine throughout the year, should we ensure the water supply temperature of cooling water, such as 32°C, according to the design conditions? The answer is no. In fact, the optimized comprehensive low energy consumption of the main engine and the cooling tower is not determined at a constant cooling water temperature, which changes with the changes of outdoor wet bulb temperature and partial load of the main engine.
