A NEW STANDARD FOR COOL COMFORT Cotes heat-driven cooling solutions provide new levels of cool air capabilities that boost control, comfort and efficiency COTES.COM
HOW IT WORKS COTES HEAT-DRIVEN COOLING Almost all the different conventional air conditioning systems consume lots of energy, and produce flows of air that may be cool but are just as humid or even more so than the ambient air. Ground-breaking Cotes heat-driven cooling solutions, based on a unique combination of advanced Cotes adsorption dehumidification and adiabatic evaporative cooling, make it possible to achieve substantially greater cooling effect with much lower energy consumption. And with the big added advantages of controlledhumidity air flows as well as the bacteria-free hygiene essential for many health care facilities, public buildings and industrial processing set-ups. A NEW STANDARD FOR COOL COMFORT Cotes heat-driven cooling solutions provide new levels of cool air capabilities that boost control, comfort and efficiency REGENERATION Waste heat or district heating 65 C Air input: Cool 18 C Dry % relative humidity Bacteria-free Warm, humid air from outside 75% relative humidity Cool comfort is important In many parts of the world, cool air is the key to a perceived sense of comfort and general wellbeing in homes, offices and public buildings. In many factories, commercial premises and public-sector buildings, cool air is the key to efficient processes, good hygiene and high productivity, as well as the wellbeing of staff, customers and the general public. But traditional air conditioning solutions, usually powered by electricity, are a hugely energy-intensive way to achieve the desired levels of comfort. Advantages and benefits The benefits of Cotes heat-driven cooling systems stem from the basic laws of physics. The drier the air, the more it can be cooled and the less energy is needed to do it. Traditional air conditioning and evaporative cooling systems can provide flows of cool air but the energy bills usually range from colossal to steep. And there s no control of the levels of humidity or of hygiene standards. By contrast, Cotes heat-driven cooling systems provide: Cooler air (normally down to approx. 18 C) Air characterised by low levels of fully controlled humidity Hygienic air flow that limits the risk of spreading harmful bacteria And do so with energy savings of up to 80% compared with traditional air conditioning or conventional secondgeneration industrial evaporative cooling systems. The energy advantage Cotes heat-driven cooling systems can exploit thermal inputs from a wide range of different sources to remove moisture from the air flow, including District heating/cooling systems Solar power installations Any kind of surplus or waste heat (-70 C) In fact, you can make use of virtually any low-cost source of thermal energy to provide an important, energy-efficient cooling capability at minimal expense. This makes these Cotes systems an ideal supplementary capability in pretty much any industrial, commercial or residential air-cooling set-up. Separate or supplementary Cotes heat-driven cooling systems are ideal as energyefficient stand-alone cooling systems. They can also be installed as pre-cooling units to supplement existing HVAC installations, providing flows of air characterised by exceptionally low, fully controlled levels of relative humidity. Because the Cotes system keeps cold and warm air completely separate, there s no risk of the spread of potentially harmful bacteria. This provides the crucial added benefit of good hygiene. This can be particularly important in hospitals, schools and other public-sector buildings and facilities. Cotes heat-driven cooling systems can be installed in a wide range of configurations, depending on the air flow specifications required.
