“Climate Battery” Controls Greenhouse Heat And Humidity
 ✖  |
Jerome Osentowski sees no reason to vent heat and humidity out of his greenhouses when he can charge up his “climate battery” instead. By blowing hot, humid air into the cool soil beneath his greenhouses, the heat and humidity are released. The air cools, and by the time it returns to the greenhouse, it is cooler and drier.
As hot air hits the cool pipes in the soil, a phase change occurs as the humid air condenses into moisture inside the pipes.
“Phase changes produce a geometric increase in the release of heat into the thermal mass of the soil,” says Osentowski.
Later, that heat is released to the greenhouses, which are set at 7,200 ft. Cool air from the greenhouse is blown into the same pipes, picks up heat from the soil, and returns to warm the greenhouse.
Osentowski compares the climate battery to a refrigeration system that moves heat from one place to another. With the correct design, a 1,200-sq. ft. greenhouse requires the equivalent equipment and running costs of a household refrigerator.
It is a system that Osentowski, along with his partner, architect Michael Thompson, has developed and spread through their firm Eco Systems Design.
“We did a simple one in the beginning and constantly updated as we built new greenhouses,” says Osentowski. “Working with Michael, we have developed the technology to industrial scale. It is now being used in huge, commercial greenhouses.”
In his book “The Forest Garden Greenhouse”, Osentowski describes the use of temperature and humidity sensors to calculate the heat stored in the soil. He also explains how to measure the discharge rate in the face of winter cold.
Available from Chelsea Green Publishing, (ph 800 639-4099), the book outlines the history, design and mechanics of the Climate Battery.
