- CreCOPlus® is specially designed for Liquid Desiccant Air Conditioner
- Its features include no corrosion risk to air conditioner, enhanced hygienic capability along with high efficiency to energy savings
- It contributes to energy saving and economy of the reason for the award
On July 1, 2021, the "Liquid Desiccant Air Conditioner to Increase The Efficiency of Heat Sources", which was jointly submitted by Evonik Japan Co., Ltd., Dyna-Air Co., Ltd., and Nikken Research Institute Co., Ltd., was awarded at the “Ministry of Economy, Trade and Industry, Agency for Natural Resources and Energy Commissioner's Award 2021” sponsored by the Heat Pump and Thermal Storage Technology Center of Japan.
In this project, Dyna-Air develops product concept and sells the product, Evonik develops and provides liquid desiccants, and NRI evaluates the energy saving of the product.
This prize is awarded to equipment and systems with excellent power load levelling effects, energy saving, and advanced technologies.
This liquid desiccant air conditioner allows to freely control the humidity and temperature of the air by adjusting the temperature and concentration of the ionic liquid. Compared to conventional air conditioning systems, cold water temperature can be increased during dehumidification and hot water temperature can be lowered during humidification, and power demand can be suppressed by greatly increasing the operating efficiency of the thermal source. For the first time in the world, ionic liquids are used in this humidifier, and Evonik's "CreCOPlus®" is adopted.
Conventionally, dehumidifiers using lithium chloride solution as desiccant have a strong metal corrosion problem, but CreCOPlus® has both equivalent moisture control performance and the feature of non-corrosion to metal materials, so it is now available to make dehumidifying machine without using expensive materials such as titanium. As a result, by reducing manufacturing costs and the amount of liquid desiccant used, it contributes to the reduction of power consumption of pumps that circulate liquid desiccants compared to conventional technology.
