Fast cooling when harvest arrives and precise regulation for optimum storage – the Agri Air Cooler is designed with agricultural freshness in mind. Designed for long or wide rooms, the Dual VARIO Air Cooler provides industrial refrigeration in a slimline design with dual air discharge. Building on nearly a century of technological and engineering exellence, we deliver impactful cooling systems for our partners.

Installation of an inline water filter (refrigerator drinking water/ice maker type) will drastically reduce the mineral deposits. Estimated cost for professional installation is about half or less that of central refrigerated air conditioning. At 40 °C (104 °F) and 15% relative humidity, air may be cooled to nearly 21 °C (70 °F). At 32 °C and 50% relative humidity, air may be cooled to about 24 °C (75 °F).

This is particularly useful in areas that experience frequent power outages. Sublimation cooling has been observed to operate on a planetary scale on the planetoid Pluto, where it has been called an anti-greenhouse effect. Porous pottery and coarse cloth maximize the area for evaporation. Also if you are living in a region with hard water, the internal parts of your cooler might corrode.

The Right Cooling Choice

In regions that are mostly arid, short periods of high humidity may prevent evaporative cooling from being an effective cooling strategy. An example of this event is the monsoon season in New Mexico and central and southern Arizona in July and August. Most evaporative coolers are unable to lower the air temperature as much as refrigerated air conditioning can. An evaporative air cooler in a closed room, without any connection or opening to the outside, cannot lower the room temperature at all by the physical law of conservation of energy.

The colored lines illustrate the potential of direct and indirect evaporative cooling strategies to expand the comfort range in summer time. It is mainly explained by the combination of a higher air speed on one hand and elevated indoor humidity when the region permits the direct evaporative cooling strategy on the other hand. Passive cooling towers lack the control that traditional HVAC systems offer to occupants. However, the additional air movement provided into the space can improve occupant comfort. An evaporative cooler is a device that cools air through the evaporation of water.

Evaporative cooling of ordinary helium forms a 1-K pot, which can cool to at least 1.2 K. Evaporative cooling of helium-3 can provide temperatures below 300 mK. These techniques can be used to make cryocoolers, or as components of lower-temperature cryostats such as dilution refrigerators. As 冷風機 decreases, the vapor pressure of the liquid also falls, and cooling becomes less effective. This sets a lower limit to the temperature attainable with a given liquid.

Thompson built a passive evaporative cooling tower, and performance data from this experimental facility in Tucson, Arizona became the foundation of evaporative cooling tower design guidelines developed by Baruch Givoni. Evaporative air cooler operates through the principle of evaporation. For instance, an evaporative cooler like Vankool uses a pump to convey water from water storage to the cooling pads which absorbs water.
