Since the reform and opening up, the rapid development of the machinery industry, the rapid development of refrigerators at this time. There are a lot of spare parts, we analyze the refrigerator open and closed cooling tower different working principle.
 Open cooling tower:
     Open type cooling tower cooling principle is, by way of circulating water to spray, spray to PVC filler, through water, air, heat up, and fan drives the air circulation tower, and the water after heat exchange with the hot air flow, thereby cooling.
  Closed cooling tower for industrial refrigerating machine:
     The cooling principle of the closed cooling tower is, in short, two loops: an inner loop and an outer loop. There is no filler, the main core part of the copper tube cooling table.
     Internal circulation: docking with the object equipment, forming a closed loop system. Cooling the object equipment to bring the heat from the object to the cooling unit.
     Outer circulation: in the cooling tower, cooling tower itself for cooling. Not in contact with the internal circulation water phase, but only through the cooling tower of the copper tube cooling heat exchanger. Under the cooling mode, the motor is set according to the water temperature through automatic control.
     Two cycles, in the spring and summer of the two quarter of the high ambient temperature, the need for the operation of the two cycle. Autumn and winter two quarter ambient temperature is not high, in most cases, only one internal cycle.
  Characteristics of closed cooling tower:
     (1) the cooling medium in closed pipe flow and the outside air is in contact with the heat of heat through the wall and external heat exchanger, air spray water heat exchanger, finally realize the cooling medium cooling device.          Therefore, the cooling medium will not be polluted, evaporated, concentrated, no need to add water, thereby ensuring the use of the associated equipment performance and life, daily management is also very convenient.
    (2) it is not necessary to maintain and operate frequently, it is stable and safe to operate, and can reduce the failure rate of the associated equipment.
    (3) because the cooling medium is not exposed to sunlight and is not in contact with the air, it will not produce algae and salt crystals.
    The utility model can be used for dry running, and can not breed all kinds of bacteria, so the utility model is especially suitable for occasions with air purification requirements, and is also often used in the areas of water shortage and dryness.
