East Star Guide to the correct operation of industrial water cooling system. East Star in the cold water machine sales and installation process found that many customers in the use of the process, there are a lot of wrong operation method. Proper operation of the cold water machine can increase the use efficiency of the chiller and increase the service life of the chiller. The correct operation method of the cooling water system is:
(1) before the start of the unit will not need to run the condenser inlet valve to close.
(2) to run the unit on the condenser on the water inlet and outlet valve (generally the water valve is normally open, the inlet valve is required to open and close. The condenser and the evaporator are the same) corresponding to the cooling water pump is opened. Adjust the condenser inlet and outlet pressure dropped to about 68.6kPa (0.7 kg/cm:) (pressure drop to overcome the resistance line, the principle. Low power saving effect is better.
(3) if the water inlet and outlet pressure of the condenser is too large, it is indicated that the cooling water system has the air.
(4) operation, both open a few units, are a cooling water pump on a host (matching to be the same).
