Evaporative refrigeration equipment is used in refrigeration, chemical, refining and other occasions. According to its cooling medium, it can be divided into three categories: water-cooled, air-cooled and evaporative.
Evaporative refrigeration equipment refers to the use of moisture evaporation and forced circulation of air to take away the heat of condensation to cool the high-temperature and high-pressure superheated steam discharged from the compressor and condense it into a liquid.
The heat transfer part of the equipment is the heat exchange tube group. The gas enters from the upper part of the heat exchange tube group and is distributed to each row tube through the header. After the heat exchange is completed, it flows out from the lower tube mouth. The cooling water is pumped to the water distributor in the upper part of the heat exchange tube group by circulating water, and the water distributor is equipped with a high-efficiency anti-blocking nozzle, which evenly distributes water to each group of tubes;
Water flows down in a film form on the outer surface of the tube, and finally falls into the pool through the filler layer on the top of the pool for recycling. When water flows through the cooler tube group, the medium in the tube is cooled by utilizing the evaporation heat of the water.
Advantages of evaporative cooling equipment:
1. Low system operation cost
2. Save initial investment
3. Save space
