In addition to products and goods, Germany’s manufacturing industry also produces a large amount of surplus energy. Increasing numbers of companies are studying the use of waste heat. As InvenSor announced at the Hanover Fair, the industry trend towards the use of adsorption cooling is continuing in 2015. Demand for simple cooling solutions from the Berlin-based manufacturer has risen significantly over the last two years. The energy-saving adsorbers with water as a refrigerant are suited for sustainable and low-maintenance cooling systems. Due to their long operating times per year, industrial applications have a particularly high potential for utilisation of adsorption chillers. Many installations pay off the investment within two to five years. In addition to being efficient, these chillers are reliable and simple to operate. Oberflächentechnik Döbeln GmbH near Dresden combines its two InvenSor adsorption chillers with two combined heat and power systems (CHP) to cool delicate galvanic baths. In trigeneration systems (CCHP or combined cooling, heat and power), the thermally driven chillers provide cooling using waste heat from the CHPs with only a minimum of electrical energy.
