This design for an ice cellar was developed by Simon Evans, PE, of the Alaska Native Tribal Health Consortium. This type of system is referred to as "active cooling," contrasting with "passive" cooling systems that use heat. Click on the image for a larger view.
Features of the design include an energy-efficient, thermostat-controlled cooling system; a solar- and/or wind-energy power system; and structural supports and ventilation for allowing exchange of cellar and outside air. This technology can be used to protect critical infrastructure from degradation during the summer months. If used correctly, it can eliminate the active layer, thus reducing infrastructure issues associated with freeze-thaw cycles.
