ZEF Climatic Table | No more air conditioning to regulate the temperature

To maintain a constant temperature in a room without energy consumption is possible in an ideal environment. In real life we would need some extra help but still could achieve a considerable expense reduction on air conditioning and heating, even of a 60% for winter and a 30% in summer.

The ZEF Climatic table is a model created by engineer Raphaël Ménard and designer Jean-Sébastien Lagrange. Made with a top panel of oak wood and an aluminum lower design, when placed in a room it would be able to keep its temperature almost constant at about 21 degrees Celsius and reduce the electricity or heating bill.

Phase change materials, the secret

This table being able to regulate the temperature of a room by itself is not a miracle. The secret lies in the material the lower panel is made of. And it is not something new. We mean the phase-change materials, which have been used in construction for several years with the same purpose: to be able to maintain the temperature inside a building hardly making electricity expense.

This kind of phase change heat accumulators have a simple initial functioning: if the room temperature rises above what has been marked as phase change, the element chosen as accumulator (for example, wax into microcapsules) melts to absorb excess heat, and this is kept until the temperature drops and once again may return to solid state, when it releases the heat accumulated in order to maintain the temperature of the room as constant as possible.
