New Commercial Big Water Tank Portable Air Cooler Working Principle CORO air cooler adopt high efficiency 'direct evaporation' technology. Temperature is reduced by water evaporation which absorbs energy from surroundings. This phenomenon is universal in our daily life. For instance, we feel cool by the sea, or we fell cool while skin covered with water drop, etc. Cooling Pad Features When fresh air pass through core part honey comb cooling pad, the water drop on the pad cools the temperature which will be close to the wet buld temperature, its features: decent water absorb ability and ventilation filter function, the realistic cooling area is a hundred times more than the surface, solid endurable against soaking, corroding, the service life at lest 6 years. Performance Characteristics Little investment, high efficiency. It can save 40% more energy than installing central air conditioning equipment . Less power consumption, low running cost, low electricity consumption per hour. FAQ Q: Are air conditioner window more suitable for specific climates ? Operating room flooring is especially well suited where the air is hot and humidity is low. However,in higher humidity areas there are many proven cost effective uses for evaporative cooling that make it the right choice,like industrial plants, commercial kitchens,laundries,dry cleaners,greenhouses,spot cooling etc. Q: What advantages does portable evaporative cooler have compared to refrigerated cooling systems ? Air cooler body plastic from alibaba china will provide substantial energy saving over refrigerated air units. The simplicity of the design allows low maintenance requirements. The portable air conditioner and other evaporative air cooler will provide fresh, filtered air. The outside air that has been cooled will blow the stale inside air out. Q: How often do I clean my pads ? Pads should be cleaned at least once a season prior to storing for the winter.In hard water areas,cleaning may be required more frequently. Periodic,visual examination is required. Remove the back or top of the cooler following the instructions in the operating manual. Look at the pads,if they show signs of heavy mineral deposits they will need to be cleaned. Q: How do I clean my pads ? Remove the pad from the unit or back panel. Rinse the pad with fresh water using a hose or soaking the pad in a tub until the mineral deposits disappear. You may want to change the tub water occasionally to accelerate the cleaning process. Allow the pad to sun dry. Reattach the pad to the cooler back panel or reinstall inside the cooler. Q: How often should the pads be replaced ? Pads should be changed when they no longer cool as effectively as they did when new. This generally happens when mineral deposits on the pads become so heavy that the water running over them during operation cannot be absorbed. If a pad is properly cleaned and maintained, its life can be three to five years or more. But, we advise customer replace the pad every 2 or 3 years to keep the best cooling efficiency. Q: How much water do I put in ? The amount of water required will vary depending on the size of the wall air conditioner you own. To help determine the correct level, each floor standing air conditioner from alibaba china is equipped with a water level indicator. It can be found on bottom sump of the unit. Add water until the indicator shoes that the water reservoir is filled. Water will leak from the unit if it is overfilled. Q: At start-up, the air has a slight odor ? Occasionally water cooling may give off a slight odor when first put into use. To eliminate this odor, run the unit for an hour, drain all the water from the tank and add fresh water. If odor persists repeat the above procedure until it is eliminated. Q: How often do I have to fill the evaporative mobile cooler container ? The length of time will vary depending on the dryness of the air and the speed at which the cooler is running. Typically water supplied should last from for one day, or half day, because we design the tank for 8 hours use or 4 hours consumption. Q: Can the pump run dry ? The unit can be safely run without water in the tank. It will cause no harm to clima air conditioner or the water pump. Never choose cooler with submersible pump that usually used in glass fish bowl.
