Carry Out The Descaling Of A Water Cooled Condenser

This scale can affect the efficiency of water cooled systems and the overall life of the equipment.

Carry out the descaling of a water cooled condenser.

Reduce the temperature of the condenser water. Scale can form thick deposits on heat transfer areas reducing water flow decreasing heat transfer and causing high head pressure. Water cooled condenser descaling method steps. Water cooled condensers involve a heat rejection loop where condenser heat is dissipated to the environment via water.

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. 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. It is know as descaling it is to be done when the condenser approach is going high like 3 4 5 c. Failure to control mineral scale formation in a cooling water system will eventually result in shut down of the plant.

Even before shut down of the system the build up of. 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. The most common type of water cooled condensers in geothermal power plants are direct contact and surface types. We look at the process of removing scale that has already developed in condensers using descaling acidic chemicals.

Therefore it is necessary that regular quarterly or at least yearly cleaning of chiller tubes is scheduled and carried out. 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. The presence of scale also forces the system s compressor to work harder. 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.

Condenser scaling usually has the following performances. 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. When water is heated or evaporated solid matter called scale often is left behind.
