Analytical chiller cooling methods

Chiller is a can provide chilled water for industrial refrigeration equipment,
It is widely used in electroplating, plastics, electronics, food, card, chemicals, machinery processing, laser and other industries. Chillers at work,
Freeze mode can be selected according to customer needs: direct and indirect freezing frozen. Many customers may not quite understand this, the following will explain in detail for you.
First, direct chilled
    Water-cooled chiller direct freezing works: Again, water-cooled chiller needs and supporting the use of cooling towers circulating chilled water pumps, cooling towers at the bottom of the basin water to the water-cooled chiller condenser by circulating chilled water pumps, thus condensing When the device cool down, and then back into the cooling tower spray down the inside, through the cooling tower sprinkler system water for cooling, and then flows back to the cooling tower basin bottom, so the cycle of operation.
 
    Condenser cooling at the same time, the inside of the R22 refrigerant liquefaction, and then flows into the evaporator to evaporate, while the need to absorb heat during evaporation, thereby to sulfuric acid (bath) was cool, sulfuric acid after cooling transported to the plating tank through the pump, which is water-cooled chiller in the electroplating industry direct freezing works.
 
Second, indirect chilled
    Water-cooled chiller indirect freezing works: water-cooled chiller needs and supporting the use of cooling towers circulating chilled water pumps, cooling towers at the bottom of the basin water to the water-cooled chiller condenser by circulating chilled water pumps, condenser order cool down. Then back into the cooling tower spray down the inside when the sprinkler system by the cooling towers for cooling water, and then flows back to the cooling tower basin bottom, so the cycle of operation.
    Condenser cooling at the same time, the inside of the R22 refrigerant liquefaction, and then flows into the evaporator water-cooled chiller tank of evaporation, and evaporation to absorb heat, which will be on the water tank of cooling water after cooling by circulating Pump fed to a heat exchanger (intermediate separated, while water, while sulfuric acid, and then through the process of heat transfer of sulfuric acid were cool. advantages of this chiller is easy to install, service life than the direct refrigeration chiller longer, and acid corrosion chiller is not easy.    
From the above comparison shows, direct water-cooled chiller freezing and indirect frozen is to have the same effect, but it is clear:
    1, there is no direct refrigeration chillers indirect refrigeration chiller safety, and direct refrigeration equipment susceptible to corrosion, in terms of shorter life expectancy compared;
    2, the direct refrigeration chillers only a slight advantage in terms of price, but the price difference is not great;
    3, from the life of the chiller to compare, indirect refrigeration chiller longer directly frozen chiller in good times;
