What to know before installing a cooling tower

Before you get a solar cooling tower, you should:

  • Decide how the feature will complement your architecture
  • Make sure you're in an area with plenty of sunlight
  • Pick an option that fits your property

Cool Towers are the Lowest energy method to cool a space. It works on the principal of cold air falling and uses gravity to move the air. A small pump is all that is required to wet the pad at the top of the tower. When the pump is controlled with our Digital Programmable pump timer, energies to cool your space can be as low as 25 watts to cool 1500 square feet! These are not only beautiful but work like magic, and are super quiet with no fans necessary, but a fan can be added to boost performance.

What are Cool Towers, and Wind Towers?

Cool towers are an enhancement on the middle eastern "wind towers" also called windcatchers, and wind scoops, that have been in use for thousands of years around the Persian Gulf. Wind towers were built in a few different configurations: four sided square, bidirectional, and unidirectional. And were built to a height of 20 to 40 feet. The towers would catch the wind and enhance the ventilation in the building when the wind blew, but they were limited to the ambient air temperature and wind: when the wind didn't blow, nothing happened, and when the wind did blew, the best you could do was bring in ambient air. But a few of these towers did have ways of cooling the air by hanging wet cloth low in the tower which would cool the incoming air with evaporation and people could occupy the space directly under the damp cloth to be cooler. And also by letting the air move down to a basement and passing it over an underground pool to evaporative cool the air, which could be channeled back up to the main floor.
Bill Cunningham did the original research on enhancing the wind towers by adding wet pads on all four sides in the intake at the top of the tower in the mid 1980's while working as a research engineer at the University of Arizona's Environmental Research Laboratory. He added wet evaporation pads on all four sides of the air intake at the top of the tower which cooled any incoming air by evaporation and the cooler heavier air would fall with the force of gravity and create and air flow even when the ambient outside air was calm.
Cool towers will create cool air and move it into the rooms below even when there is no wind. And the tower will cool the air as much as 30 degrees F! How do they do this? By using gravity and water. Air flow in a cool tower is the function of many things, including the geometry of the tower & the pads, and the temperature and humidity. This downdraft chimney is the reverse of an updraft chimney where hot or warm air rises. Predicting and calculating the airflow that can be created requires a fair amount of math
Pad thickness and size will have a big efect on the cooling performance. This is true because the pads can be the biggest resistance or friction to the airflow. Conventional aspen cooler pads do not work as well as rigid media type of wet pad.

Considerations for Cool Towers:

  • Cool towers can work very well if designed properly, and the building exhaust air must also be designed with prevailing wind directions. Windows, doors, and exhaust towers may be used.
  • The structures tend to be big and expensive if they are made to cool an entire home.
  • Building codes may require wind and earthquake forces and loads which will require engineering for the structure, and also require engineering for the airflow and pad configuration.
  • Due to the high cost of a Cool Tower, our Solar Chill Coolers may be more cost effective, and work more reliably.
