NEW HIGHLY EFFICIENT HFC BASED GEOTHERMAL PROCESS FOR A FRENCH WINERY

NEW HIGHLY EFFICIENT HFC BASED GEOTHERMAL PROCESS FOR A FRENCH WINERY

02.12.2014

An innovative geothermal R-410A heat pump system has been installed by an Alsace winery in its winemaking plant.

Two R-410A geothermal heat pumps, controlled by an innovative energy efficient process with a COP of 7 to 10 – nearly twice the performance of similar heat pumps – are connected to 23 vertical 100 m long earth tubes. They deliver 110 kW heat or 90 kW cooling to the winery’s stainless steel fermentation tanks. The 23 earth tubes represent a ground heat reservoir of around 170,000 m3.

The process allows control of the fermentation process, cooling or heating the tanks when appropriate, storing excess heat in the ground or heating the buildings and distributing hot water in the offices.

The project received the Geothermal award trophy for 2014.
