Evaporative Cooling Overview
Evaporative Cooling is based on the interaction of heat (environmental air temperature) and moisture (air humidity). To produce a cooling effect, certain conditions must exist. So before you invest in an Evaporative Cooler, it is important to understand what it is and whether it is the right "tool" for your cooling job.
The following information is a simple, basic overview of the process. We hope you find this helpful and we appreciate your business.
How does Evaporative Cooling Work?
- Hot air is drawn in and forced through water.
- The heat within the air transfers to the water. As a result, the heated water evaporates.
- The air exiting has lost heat, is lower in temperature and contains evaporated water.
The amount of temperature reduction and unit efficiency is effected, for the most part, by two factors:
- The TEMPERATURE of the environmental air.
- The HUMIDITY LEVEL of the environmental air.
One component of the process is based upon transferring heat from the air to the water. The higher the temperature of the air, the more heat that may be transferred as it passes through cooler water. In contrast, when the air temperature is cooler and closer to the water temperature less heat will be transferred.
This is the amount of water contained in the air. Transferring heat from the air to the water results in evaporation of the water. However, the more water that is in the environmental air (humidity) the less it can accept. (An example is a damp sponge. The more water in the sponge, the less it will soak up.) Many people neglect considering the impact of humidity on cooling, but it is a primary factor.
SEE: Temperature vs. Humidity Chart below.
So generally, what should you consider?
The greatest cooling effect will be obtained with a combination of a hot, dry environment. (Examples of locations where this often occurs: Arizona, Nevada, New Mexico, West and extreme Southwest Texas.)
The amount of cooling declines as the environment becomes more humid. Even though these areas can be extremely hot, the humidity impacts the evaporation ratio. (Examples of locations where this often occurs: South Texas, Louisiana, Mississippi, Alabama, Florida.)
Many of our customers travel or have various locations to manage. Although, evaporative cooling might not be a great choice for one area, you may find this method very helpful and cost effective in other locations.
Other appliances, equipment or structures may affect the environmental conditions. (A few examples: Other equipment that generates heat when in use; A/C units which are lowering the humidity but aren't sufficiently lowering the temperature; Whether cooling is needed in an open or partially exposed area, or in an area that is completely enclosured and insulated.)
One distinct advantage Evaporative Cooling units have over A/C units is the ability to use them outside. They are often a great choice for garages, open awnings, patios and as travel gear.
Time of Use
Temperature and humidity levels can vary greatly during different times of the day. Likewise, some geographical areas experience wind shifts during the day that can affect temperature and moisture. Consider when you need cooling and what the conditions are during that time.
Everyone is different. Your personal preferences will determine what is comfortable and acceptable for your cooling needs.
Cost vs. Cooling
Economics are also a consideration. The efficiency and comfort of evaporative cooling costs should be weighed against the results of A/C technology costs for your personal situation.
As in A/C technology, Evaporative Cooling products will typically indicate the cooling capacity in square footage. But just like A/C technology, this does not take into account whether doors/windows/walls/etc. will be open and how long it takes to acclimate this amount of space. These issues are universal to any cooling method.
Temperature vs. Humidity Chart
The following is a generalized chart to suggest possible Evaporated Cooling results. It is offered as a tool to visualize how the factors of humidity and air temperature impact the output air temperature.
TO USE: Find the intersection of the Environmental Air Temperature (°F) that will be going into the Evaporative Cooler (green column) and the Environmental Humidity Level (blue row). This is a general idea of the temperature of the air coming out of the Evaporative Cooler.
(For example: If the air in our shop is 100° with 15% humidity, the air coming out of the unit is going to be approximately 76° F.)
