The outside air comes in contact with water inside the tower either through a wetted membrane or a mister. As water evaporates in the outside air, the air becomes cooler and less buoyant and creates a downward flow in the tower. At the bottom of the tower, an outlet allows the cooler air into the interior.
Evaporative cooling is most effective when the relative humidity is on the low side, limiting its popularity to dry climates. Evaporative cooling raises the internal humidity level significantly, which desert inhabitants may appreciate as the moist air re-hydrates dry skin and sinuses. Therefore, assessing typical climate data is an essential procedure to determine the potential of evaporative cooling strategies for a building. The three most important climate considerations are dry-bulb temperature, wet-bulb temperature, and wet-bulb depression during a typical summer day. It is important to determine if the wet-bulb depression can provide sufficient cooling during the summer day.
High efficiency in a slimline design, the space-saving Slim COMPACT Air Cooler is made with small and low cold stores in mind. The flat design occupies very little space allowing optimal use of your cold room. What’s more, all of the COMPACT coolers come with a 3-year warranty as standard, giving you even more peace of mind. Mold and bacteria may be dispersed into interior air from improperly maintained or defective systems, causing sick building syndrome and adverse effects for asthma and allergy sufferers.
How a CPU Cooler Works
Hot winds, known as “loo” and low humidity become quite common during the long days of summer. These harsh conditions force people to adopt certain measures such as buying air conditioners and air coolers to survive the stifling temperatures. Air coolers increase humidity – The major disadvantage of an air cooler is its dependency on the climate. In areas with very high humidity, the coolers may prove to be less efficient.
For arid climates with a great wet-bulb depression, cooling towers can provide enough cooling during summer design conditions to be net zero. For example, a 371 m2 retail store in Tucson, Arizona with a sensible heat gain of 29.3 kJ/h (100,000 Btu/h) can be cooled entirely by two passive cooling towers providing m3/h each. A mechanical direct evaporative cooler unit uses a fan to draw air through a wetted membrane, or pad, which provides a large surface area for the evaporation of water into the air. Water is sprayed at the top of the pad so it can drip down into the membrane and continually keep the membrane saturated.
L / 45 L – Desert Air Coolers
Striker Tall Desert coolers are designed to keep you comfortable by providing airflow at the seated level. They come in large capacities and thus provide uninterrupted supply of cool air for longer periods. Usha Azzzuro Window cooler was designed keeping convenience in mind. It comes with a rotatable front water inlet and an auto tank fill feature to make water filling as easy as possible. Moreover with its powerful airflow Azzuro becomes one of the best choices to beat the heat this summer.

The cooler’s pads are saturated by pumping water from the bottom to the top part of the unit and allowing it to flow down all over the pads. Air is then pulled through the pads using a powerful blower resulting to evaporation and the resulting cooler air is blown out at a very high speed. Cooling towers are structures for cooling water or other heat transfer media to near-ambient wet-bulb temperature. Wet cooling towers operate on the evaporative cooling principle, but are optimized to cool the water rather than the air. Cooling towers can often be found on large buildings or on industrial sites. They transfer heat to the environment from chillers, industrial processes, or the Rankine power cycle, for example.
Humidity really matters when it comes to the efficiency of evaporative coolers. This is because swamp coolers cool the air by filtering it through water and lowering its temperature. The fresh air that is coming from outside gets filtered through a saturated evaporation. The production of humid air results from the absorption of some water during the cooling process. Therefore, 噴霧機 can see that swamp coolers will only work best when only small amount of warm dry air circulates into your home while the system is on. Therefore, the lower the humidity levels, the better the results when using an evaporative cooling.
