The cooling principle of cold water direct freezing in electroplating (oxidation) industry is that the water in the bottom basin of cooling tower is transferred by water pump to the condenser of the chiller to cool the condenser, and then flows back to the cooling tower through the fan on the top to cool the water and then flows back to the bottom basin of cooling tower.

The chiller in the production process should ensure the normal operation of the air-conditioner after starting. It must be ensured that the condenser has good heat dissipation. Otherwise, the condensing temperature and the corresponding condensing pressure will be too high, so that the high-pressure protection device of the chiller will stop and even cause malfunction.

In the previous section, the attention points to be paid to the connection of condenser line in the installation process of water-cooled chiller were introduced in detail. In this section, the attention points to be paid to the connection group of evaporator line of water-cooled chiller were introduced in detail:
