STARRINKS.COM JULY.AUGUST.2016 / 43 Following the inspection, he spent the rest of the day cleaning the water basin and the spray nozzles, and then ordered two new fan belts and a new fan shaft bearing. As it turns out, the scale buildup on the coils was severe enough that he decided to call a local refrigeration company to acid clean them and inspect the water treatment system the following week. They found that one of the chemical feed pumps had stopped working, and the basin water bleed valve was not working properly, so the concentration of dissolved solids in the basin water was higher than it should've been. Out of all the components in a refrigeration system, the condenser has one of the most profound effects on the efficiency of the system. The role of the condenser in a refrigeration system is to transfer the heat absorbed by the primary refrigerant (Freon; ammonia) during the cycle of refrigeration, to the atmosphere. This transfer of heat allows the primary refrigerant to condense from a high pressure, high temperature gas to a lower temperature liquid. Scale buildup on the coils and related components in an evaporative condenser reduces heat transfer and consequently causes the compressors in the system to work harder and run longer due to higher head pressures. In fact, it has been shown that as little as 1/32" of calcium scale buildup on condenser coils can reduce heat transfer by up to 27 percent. What is the moral of this story? Frequent visual inspections of the condenser and the associated water treatment systems designed to control scale buildup, inhibit corrosion and bacteria growth can save your rink a significant amount of money in the long run.
