In the coming years, temperatures will rise worldwide. This means that we rely more and more on cooling equipment in the summer months. In comparison to conventional devices this curtain is a self maintaining cooling/warming system without using electricity.
The curtain is screen printed with phase changing material.
Above 25°C the microencapsulated PCM absorbs heat when it’s changing from a solid to liquid state. When the room temperature drops again the absorbed heat is released.
At the window, the warm air develops first (heating by solar radiation / insulation weak spots). PLUS MINUS 25°C is designed to absorb and release heat when needed. It has a cooling effect in summer because the curtain directly extracts heat from the incoming air. At the same time, it has a warming effect in winter. The curtain absorbs the warmth of the sun and the heater, releasing it to the room during the night. This turns the curtain into a self maintaining cooling/warming system
This curtain can be a solution to support saving energy in buildings - at home, in public spaces and offices. Depending on the setting, the curtain can be customised in size, layers of material, fabric and patterns, to generate the best effect.
