Closed Cooling Loops (A/C System)

General Description
      A chiller system is used in removing of heat from a liquid (mainly water) by avapor-compression or absorption refrigeration
cycle theories this liquid can then be circulated again and again through a heat exchanger to cool air or equipment as required.

Chillers in Industry can be used for
        controlled cooling of products.
        Mechanisms and factory machinery in a wide range of industries.
        plastic industry in injection and blow molding.
        metal working cutting oils, welding equipment.
        die-casting and machine tooling, chemical processing.
 
   

Chillers can be classified into..

   1. Water-cooled .
        Constrict for indoor installation and operation, and are cooled by a separate condenser water loop and connected to outdoor cooling   towers to expel heat to the atmosphere.

 
   2. Air-cooled.
       Constrict for outdoor installation and operation. Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere.



   3. Evaporative cooled.

Evaporative cooled depend on the implement a mist of water over the condenser coil to aid in condenser cooling.

Common Closed Cooling Loops problems ...
Corrosion ..

       Corrosion is the primary means by which metals deteriorate.

Most metals corrode on contact with water (and moisture in the air), acids, bases, salts, oils, aggressive metal polishes, and other solid and liquid chemicals.

  

       Metals will also corrode when exposed to gaseous materials like acid vapors,formaldehyde gas , ammonia gas, and sulfur containing gases.
 

       Corrosion specifically refers to any process involving the deterioration or degradation of metal components.

The best known case is that of the rusting of steel.

Corrosion processes are usually electrochemical in nature.
