Q: What is the physical working principle of evaporative air cooler?
Evaporative coolers lower the temperature of air using the principle of evaporative cooling. Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature. The energy needed to evaporate the water is taken from the air in the form of sensible heat, which affects the temperature of the air. The evaporation rate depends on the temperature and humidity of the air.A simple example of natural evaporative cooling is perspiration, or sweat, secreted by the body, evaporation of which cools the body.
Q: What's the difference between portable evaporative air cooler and air conditioner?
An evaporative cooler (also swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of people.
Q: What kind of climates are suitable for portable evaporative air cooler?
Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. As evaporative air conditioning is so popular and well-suited to the dry and arid areas. So it is also called desert cooler. In locations with moderate humidity there are many cost-effective uses for evaporative cooling, in addition to their widespread use in dry climates. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses, spot cooling (loading docks, warehouses, factories, construction sites, athletic events, workshops, garages, and kennels) and confinement farming (poultry ranches, hog, and dairy) often employ evaporative cooling.
Q: How often should the cooling 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 the customer to replace the pad every 2 or 3 years to keep the best cooling efficiency.
Q: What advantages does portable evaporative air cooler have compared to refrigerated cooling systems?
1. Less expensive to install and operate: Estimated cost for professional installation is about half or less that of central refrigerated air conditioning. In dry, arid climates, the installation and operating cost of an evaporative cooler can be much lower than that of refrigerative air conditioning, often by 80% or so. The working fluid is water. No special refrigerants, such as ammonia or CFCs, are used that could be toxic, expensive to replace, contribute to ozone depletion and/or be subject to stringent licensing and environmental regulations.
2. Ease of installation and maintenance: Equipment can be installed by HVAC contractors at much lower cost than refrigeration equipment which requires specialized skills and professional installation. Some mechanical parts in most basic evaporative coolers like the fan motor, the cooling pad and the water pump, etc. All of them can be repaired or replaced at low cost.
3. Ventilation air: Evaporative cooling increases humidity. In dry climates, this may improve comfort and decrease static electricity problems. The honeycomb cooling pad itself acts as a rather effective air filter, it is capable of removing a variety of contaminants in air, including urban ozone caused by pollution, regardless of very dry weather.
