SorTech AG offers free software to calculate the economic viability of adsorption-based air-conditioning solutions. The SorTech Quick-Check software tool displays a recommendation within seconds whether spending on adsorption equipment will make economic sense for a given application. The issue of “cold from heat” is not new, but application of power and CO2-saving adsorption chillers to generate cold from low-temperature heat is. Basic information taken into consideration includes: cold demand, heat source and annual cooling period. The software is available on the homepage of SorTech’s website.
