Résumé

This paper presents field results of a CO2 transcritical water chiller installed in a winery in North Italy. The unit is designed to cool down glycol, which keeps must temperature under control during fermentation; different water temperature level might be required according to specific step in the wine production process. Waste heat can also be recovered at high temperature, for cleaning purposes. A transcritical low pressure receiver design, with flooded, natural circulation evaporator is implemented. Data from the field are collected and analyzed to assess energy performance and useful effects under different boundary conditions and load requirements. Field data analysis, which are still ongoing, will allow for proper fine-tuning of the controller setup.
