The Groundfridge is an autonomous operating and active cooled cellar: an development version of the traditional root cellar for today’s sustainable companies and cosmopolitans with their own vegetable garden and who lead modern, self-providing lives. The Groundfridge uses the insulating capacity of the ground and the cooler night air temperatures. This allows the temperature within the Groundfridge to remain steady and cool throughout the entire year – the perfect temperature to store, for example, fruits, vegetables, wine and cheese.
The lightweight Groundfridge is very easy to transport and install and placing it doesn’t require any permits like a normal cellar would.
How does it work?
The Groundfridge is dug in and covered up with the soil that was taken from its new lodging place. This covering layer of soil is about 1 meter thick and has sufficient stabilizing properties for the core temperature within the Groundfridge to barely vary. It uses the cooling effect of the groundwater as well, if present.
The Groundfridge is equipped with a professional Peltier cooling device for periods with higher outdoor temperatures.This cooling device can be powered by solar panels. The device uses a limited amount of energy and also circulates the air inside to keep your food fresh for a longer period of time.
12 refrigerators, minimum electricity
The Groundfridge has a total volume of 7.85 m3: It is big enough to stand in with 2 people, and has a storage capacity of 3,000 liters. This equals the content of 12 large family refrigerators that can store 500 kg of food.
