Analysis of cooling tower refrigeration cooling system application form

The classification form of cooling tower cooling system for refrigerator according to the cooling water directly into the cold water machine equipment division can be divided into two categories: direct and indirect cooling system cooling system, two cooling methods have their respective advantages, to ensure water machine company's products and services at the same time, the East Star Refrigeration line responsible attitude, brief introduction of cold water machine with a cooling tower cooling way convenient for customer selection.

1、Indirect cooling tower cooling system: refers to the refrigerator circulating cooling water loop and cooling water loop are independent of each other, not connected, energy transfer mainly depends on the intermediate heat equipment to carry out. The biggest advantage is to ensure the integrity of the loop of the chilled water system. The sanitary condition of the loop is guaranteed, but the cooling effect of the cooling effect is decreased because of the heat exchange loss in the middle. Added a plate heat exchanger in the original refrigeration water system. In the cooling tower, closed refrigeration unit, cooling water and chilled water are respectively connected with heat exchanger, which realize the energy transfer.

2、Cooling tower direct cooling system: refers to set the bypass pipe in the original chiller water system, chilled water system and cooling water loop to loop connected together. In the summer, according to the conventional chiller water system operation, turn into the cooling tower for cooling, the refrigeration unit is closed, open the bypass through the valve, so that the cooling water directly into the user terminal. The cooling tower in the system can be opened and closed. When the open type cooling tower is adopted, the cooling water is directly contacted with the outside air to easily be polluted, and the dirt is easy to enter the indoor air water regulating pipeline with the cooling water. Although the closed cooling tower can meet the health requirements, it is affected by the indirect evaporative cooling principle, the heat transfer effect is affected, and the closed cooling tower is less used in the domestic, so it is seldom used.
