A condensing coil is a type of heat exchanger that functions to transfer heat between given mediums with efficiency. These useful gadgets are found in air conditioners, space heaters, and car radiators among others. Its primary purpose in all the mentioned devices is heat transfer. This involves all the processes that deal with heating and cooling systems and coils. The shape of the coil resembles that of the snake and has many sets of complex internal tubing that is in charge of managing the heat transfer process.
In the refrigeration cycle and vapor compression, the condensing coil acts as the evaporator. The cycle occurs repeatedly to supply the whole building with fresh air. Most condenser units are self-maintaining, but there might be occasional break-downs. This might be due to a couple of things that include corrosion and scaling.
The control of corrosion is done by maintaining the chemistry of water in circulation in prescribed condition. Where the re-circulating water has some dissolved elements, the bleed method is used to control their concentration. In the method, a continuous flow of the small portion of the re-circulating water is used. The quality of the ambient air in the heating and cooling system will vary from one site to another. It is highly recommended that when there is need for maintenance, the services of an expert in water treatment and system cooling should be sort so that the functionality of the system afterwards is not compromised. Expert advice should also be sort on the appropriate temperature at which the water should continuously run.
The system is also exposed to spoilage if it is maintained without adequate biological control. The warm oxygen found in the heat coil plus the nutrients that are found in the system provide a breeding place for slime, algae and many other micro-organisms. As the organisms increase, the capability of the condensing coil to control heat transfer is reduced making it less efficient. It is therefore possible to undertake a maintenance practice without knowing the reason for the inefficiency and end up ruining the whole system instead.
Under biological control, a biocide program is initiated in the system. Solid or granular biocides are installed through a given chemical pot feeder parallel with the circulating pump. Additionally, diluted biocides can be put into the cold water basin and the concentration of the ozone water should not exceed 0.5ppm if it has to be used. It is also recommended that the whole system be drained during the maintenance process to minimize the chances of biological contaminations. This should be for a period of three days or more so that enough time is allowed for the whole process to be completed.
When about to resume operations, all the debris should be cleaned that is in the cold water basin and re-fill it with fresh one. The water should then be treated with the biocide that was used during the maintenance process. After all this is done, the condensing coil should be able to resume its normal working condition.
