Evaporative Cooling System
Evaporative cooling system is working by using water’s large enthalpy of vaporization. The temperature of dry air can be dropped significantly in transition of liquid water to water vapor (evaporation), which can cool air using much less energy than refrigeration. Evaporative cooling device requires a water source, and must continually consume water to operate.
The Essence of Evaporative Cooling System Service
It is necessary to maintain your cooling system on a regular basis. Evaporative cooling systems are energy efficient in comparison to refrigerant air conditioner although they consume a lot of water. Essentially, you can reduce the water consumption of your system through the proper maintenance. HVAC companies offer maintenance service plans for evaporative cooling systems. Regular service can help you reduce the amount of water used in the evaporative cooler and reduce cost of power. It is ideal to get your evaporative cooling system serviced at least once a year, perform basic maintenance including the replacement of the pads to enhance system durability.
Notably, there are various evaporative coolers on the market, and each system has specific instructions regarding maintenance from the manufacturers. Monthly inspection and cleaning is essential to ensure that parts are functioning properly, and to help you identify the problem early in advance, so you can contact heating & cooling professionals before your system breaks down completely. The cooler itself should be drained in addition to being cleaned periodically. While performing the monthly inspection, unplug the unit and check for any wear and tear. Check the water level in the reservoir and ensure that pad is well watered. Please note that algae need light, moisture and nutrients to survive. Algae growth damages the evaporative pads. Moreover, evenly watered evaporation pads lasts longer. When you ensure proper water distribution, sweep the dirt settled on the pad when you flush the water and remove harmful contaminants that can damage the pad. Pad maintenance is imperative because it affects the performance of your evaporative cooling system.
You should routinely check and replace the cooler pads. Ask your HVAC specialist to recommend cooler pad for your system, because there are different fiber and rigid-sheet pads available for the evaporative cooler systems. Fiber pads are cheaper and require more maintenance that rigid-sheet pads. You need to replace them at the beginning of the cooling season and then at mid-season. Rigid-sheet pad are thicker and are more expensive but are cheaper to maintain in the long run because they do not require frequent replacement. The pads circulate the air through a stack of corrugated sheet material.
Ultimately, pad replacement is essential because most evaporative coolers use hard water. As a result, the pads wear out because of the dissolved contents in the water. During evaporation, the hard water leaves mineral deposits on the pad surface. Consequently, the deposits impact the pad efficiency and reduce the life span by half. In addition, the hard water causes corrosion and rust on metallic coolers. Therefore, you need to check pad constantly and replace it if needed to prolong the life of your evaporative cooling system.
Differences between A/C Units and Evaporative Coolers.
Evaporative cooling system is less expensive to operate and cost of installation is about half of the price of central air-conditioning. Evaporative cooler uses water as refrigerant and there is no toxic refrigerants contributing to ozone depletion. The only mechanical parts are water pump and fan motor and both parts can be repaired or replaced at low cost. The pad acts as an effective air filter and it is capable of removing a variety of contaminants. But there are some disadvantages as well. High humidity decreases the cooling service capability of the evaporative cooler that is why they are mostly being installed in dry western climates. There is no dehumidification like with regular A/C unit, which removes moisture from the air.
Evaporative cooling system supplies air with 80-90% humidity and as we know very humid air accelerates corrosion and this can reduce life of electronics and other type of equipment. The evaporative cooling system is a common place for mosquito breeding and source of mold and bacteria in indoor air if improperly maintained. Before you make you decision about installing evaporative cooler talk to HVAC professional if this is right choice for you.
