20090065188 | Water quality control method for an evaporative cooling water chiller and a system thereof - A water quality control method for an evaporative cooling water chiller uses a water pump to transport cooling water from a water tank to a water-spraying element via a water pipe. The cooling water is sprayed onto fins and a refrigerant pipe of a first heat exchanger, flows along the fins and is collected in the water tank. Thereby, the cooling water reduces the temperature of the heat exchanger. The water pump is set to operate for a first period and to stop for a second period so that the temperature of the fins and the refrigerant pipe increases. Thereby, the limescales attached to the heat exchanger are detached and drop into the water tank. Subsequently the water pump is turned on again. The cooling water in the water tank flushes out the accumulated particles on the bottom of the water tank, and clean cooling water is added. | 03-12-2009 |
