Carry Out The Descaling Of A Water Cooled Condenser

Even before shut down of the system the build up of.

Carry out the descaling of a water cooled condenser.

Water is used to cool the hot air refrigerant 180 f or 82 c from the compressor by pumping counter flow water in the condenser. The most common type of water cooled condensers in geothermal power plants are direct contact and surface types. I recently received an email from chris molyneaux of air treatment engineering and maintenance in durban in which he wrote that while getting technical had covered the prevention and control aspects of scaling in water circuits we in the. Reduce the temperature of the condenser water.

We look at the process of removing scale that has already developed in condensers using descaling acidic chemicals. When water is heated or evaporated solid matter called scale often is left behind. Chemical descaling of condensers maximizes efficiency on october 10 2016 in chiller tube cleaning cooling tower cleaners descaling chiller units open loop or closed loop naturally experience performance degradations over time. Plate type heat exchangers a special kind of surface exchanger are also possible but appear to be more common in liquid to liquid heat transfer applications.

Reducing the temperature of the water entering the condenser of an industrial chiller significantly improves efficiency as it has to work less to exert its overall cooling. Water cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water. Scale can form thick deposits on heat transfer areas reducing water flow decreasing heat transfer and causing high head pressure. Condenser scaling usually has the following performances.

It is know as descaling it is to be done when the condenser approach is going high like 3 4 5 c. Water cooled condenser descaling method steps. This scale can affect the efficiency of water cooled systems and the overall life of the equipment. The presence of scale also forces the system s compressor to work harder.

Descaling compound mineral scale forms in the hot parts of the cooling system like heat exchangers and condensers. The cleaning liquid can be added to the cooling water system in a certain proportion and the cooling pump is turned on for 12 to 24 hours. First check the scaling. Water cooled air conditioner is also called water cooled condenser as its function is to reject the heat that was absorbed by the refrigerant in the evaporator.
