Furniture that accumulates thermal energy

This table from designers Raphaël Ménard and Jean-Sébastien Lagrange collects and transfers the thermal energy, depending on the temperature in the room. Table – the first piece of a series of Zero Energy Furniture ("furniture with zero energy consumption"). The table top is made of solid oak, its bottom – corrugated anodised aluminium, and the legs are oak and are reminiscent of props for trees.

The table accumulates heat when the room temperature is above 22°C, and when below – gives. Between wooden bench tops, and crimped aluminum is a special material PCM (Phase Change Material, "the material phase change"), which melts at a temperature of 22°C by absorbing heat from the ambient air. Accordingly, when the temperature drops, the wax solidifies and gives off heat. Initially, the PCM used in construction.

Aluminum transmits heat well, and the corrugated shape increases the surface area, which increases the heat transfer between the room and the PCM.

Solid oak was chosen for aesthetic reasons, but also because of its thermal properties. It is a good insulation material, so the heat transfer is from the other side is aluminum, and the person more comfortable to sit at the table.

According to designers, the proposed technology can be very effective in open office spaces, meeting rooms, classrooms, restaurants.published
