Chemical water chiller water quality requirements to explain

Softening of water, in the use of cold water machine process, is also a problem that can not be ignored, to the pH value of water needs to be constantly observed, the optimum pH value should be equal to 7, low temperature thermostatic bath, greater than 7 pH would have dire corrosion phenomenon, if do not adopt measure, will be in the evaporator, mold scaling, will play a heat insulation role, serious when, its energy conversion effect by 30%.

This obviously requires consideration of hard water softening. The most effective method, can be configured into the system a softener, such softener to ion exchange principle design. According to the different flow can be configured to different specifications of the softener, direct connection in the cycle water pipeline, the general configuration of water treatment softener costs will not be too high, can also be set during the circulatory system by adding certain amount of detergent.

Electroplating industry how to chiller selection?

For electroplating, electrophoresis coating, plating production lines, anodic oxidation, are directed to the plating tank inside the electroplating liquid cooling. How to select the chiller. Cooling mode has two kinds, direct cooling and indirect cooling.

Water cooled chillers cooling machine in electroplating ( oxidation ) industry refrigeration principle: the cooling tower basin at the end of the water pump to work through the water chiller condenser condenser to cool, and then flows back to the cooling tower spray down through the cooling tower fan cooling water flows back to the cooling tower basin, so the operation of go round and begin again.

The condenser heat while inside the refrigerant liquid, then flows into the cold bore within the evaporator for evaporation, and evaporates to absorb heat, thus the cold bore in sulfuric acid (bath ) is cooled by cooling, sulfuric acid pump to plating ( oxidation ) slot, so a cyclic process.

Water cooled type indirect freezing in electroplating ( oxidation ) industry refrigeration principle: cooling tower bottom pot water through the pump to the chiller condenser, the condenser cooling. And then back into the cooling tower spray down through the cooling tower fan for water cooling, then flows back to the cooling tower basin at the end of the run, so go round and begin again.

The condenser heat while inside the refrigerant liquid, then flows into the water tank of the evaporator for evaporation, and evaporates to absorb heat, thus the water in the water tank for cooling, cooling water through the pump to the heat exchanger ( intermediate spaced, side side water, sulfuric acid, through heat transfer process of sulphuric acid cooling, so a cyclic process. )

Cold water machine is generally used in air conditioning units and industrial cooling. In the air conditioning system, chilled water is usually assigned to the heat exchanger or coils in air handling units or other type of terminal equipment cooling in its respective space, and cooling water is re-circulated back to the cooling by cooling. In industrial applications, chilled water or other liquid cooling pump through the process or laboratory equipment. Industrial chiller is used to control products, and factory machinery cooling mechanism of all walks of life.
