In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. Evaporative coolers lower the temperature of air using the principle of evaporative cooling, unlike typical air conditioning systems which use vapor-compression refrigeration or absorption refrigeration. Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature. This conversion of sensible heat to latent heat is known as an isenthalpic process because it occurs at a constant enthalpy value. Evaporative cooling therefore causes a drop in the temperature of air proportional to the sensible heat drop and an increase in humidity proportional to the latent heat gain. Evaporative cooling can be visualized using a psychrometric chart by finding the initial air condition and moving along a line of constant enthalpy toward a state of higher humidity.
Because of this, evaporative coolers use only a fraction of the energy of vapor-compression or absorption air conditioning systems. Unfortunately, except in very dry climates, the single-stage cooler can increase relative humidity to a level that makes occupants uncomfortable. Evaporative cooling is especially well suited for climates where the air is hot and humidity is low. In the United States, the western and mountain states are good locations, with evaporative coolers prevalent in cities like Albuquerque, Denver, El Paso, Fresno, Salt Lake City, and Tucson.
Any excess water that drips out from the bottom of the membrane is collected in a pan and recirculated to the top. Single-stage direct evaporative coolers are typically small in size as they only consist of the membrane, water pump, and centrifugal fan. The mineral content of the municipal water supply will cause scaling on the membrane, which will lead to clogging over the life of the membrane.
It is powered by a solar panel array which also serves as secondary power in case of main power loss. Evaporative cooling is a common form of cooling buildings for thermal comfort since it is relatively cheap and requires less energy than other forms of cooling. Another application of a phase change to cooling is the “self-refrigerating” beverage can. A separate compartment inside the can contains a desiccant and a liquid.
In dry climates, this may improve comfort and decrease static electricity problems. Use a rule of thumb which estimates that the wet bulb temperature is approximately equal to the ambient temperature, minus one third of the difference between the ambient temperature and the dew point. With a 40-liter tank capacity, this air cooler serves the best in smaller spaces. The ECM-4500 Plus is energy-efficient and environment-friendly with a unique design. They are capable of spreading air equally inside the room as they are much bigger. Moreover, these air coolers are the best when it comes to saving floor space.

The result is a constant flow of fresh, moisturized, cool air while stale air is circulated out of the room through an open window or door. Evaporative air coolers are rated according to the amount of air-flow that they can generate. This is why they are actually grouped according to air flow per minute. The total quantity of air that a cooler unit can pump per unit time can be measured in either CFM , CMM , or CMH . The key to choosing your ideal evaporative cooler is choosing one with the right rating for your space. Therefore, you need to first calculate the CMH(m3/h) requirement of your cooler if you are seeking to know the right number of coolers to buy for your space.
NasGas offers some of the best quality and reasonable air coolers that are also energy-efficient and environment-friendly. 冷風機 cool the air inside your room and once your is room hot it cools the same air again, whereas air coolers use fresh outside air, cool it and direct it inside the room. To calculate the power consumption of your air cooler you will need to know the rated power of your air cooler. The new Aerostyle range of air coolers form Usha are the perfect blend of style and performance.
Why evaporative cooling could be an ideal solution for industrial places
Traditionally, evaporative cooler pads consist of excelsior inside a containment net, but more modern materials, such as some plastics and melamine paper, are entering use as cooler-pad media. Modern rigid media, commonly 8″ or 12″ thick, adds more moisture, and thus cools air more than typically much thinner aspen media. The M-Cycle is not limited to cooling systems and can be applied to various technologies from Stirling engines to Atmospheric water generators. For cooling applications it can be used in both cross flow and counterflow configurations. Counterflow was found to obtain lower temperatures more suitable for home cooling, but cross flow was found to have a higher coefficient of performance , and is therefore better for large industrial installations. Air coolers are noisy – The fan in the air coolers makes noise which might be disturbing for some people, however in my view it will be easily ignored once a gush of fresh cool air hits your body.
Cooling with Air
Blue synthetic pads do not absorb and hold water efficiently like aspen pads. Aspen pads lose efficiency with time because of the buildup of water and minerals absorbed. •Aspen pads tend to give off an aspen woodsy odor through the vents. A slim form factor leaves plenty of space for an optional fan and helps the T120 slip into numerous builds without blocking RAM or GPU slots.
