The ESyCool green system which provides supermarkets with energy efficient refrigeration and heating in one system was the success project of Viessmann. The system is combining multiple innovative concepts: By using small, hermetically sealed refrigeration circuits the amount of needed refrigerant is decreasing. The necessary electricity is gained through photovoltaic systems. Moreover, ESyCool green is equipped with a storage for excessive heat and power.
The first place of the category „energy efficient cooling and air conditioning with indirect refrigeration“ has been awarded to Menerga GmbH.
