A refrigeration facility (1) is provided with: a refrigeration space (12) placed at below freezing a heat exchanger (13) for cooling the refrigeration space (12) and bringing the refrigeration space (12) to below freezing an electroconductive conveyance device (15) disposed in the refrigeration space (12), on which a food and drink product (XA1) is mounted casters (26) for isolating the conveyance device (15) from a floor surface (17), a side surface (18), and a ceiling surface (19) forming the refrigeration space (12) a power source terminal (30) connected to the conveyance device (15) a power source device (16) for applying an alternating-current voltage and a direct-current voltage simultaneously to the food and drink product (XA1) via the power source terminal (30) and a control device (22) for controlling the alternating-current voltage value and the direct-current voltage value applied to the food and drink product (XA1) by the power source device (16) while referencing each of the alternating-current current value and the direct-current current value or the alternating-current voltage value and the direct-current voltage value supplied by the power source terminal (30). This refrigeration facility (10) places the food and drink product (XA1) in a supercooled state.La présente invention concerne une installation frigorifique (1) pourvue : dun espace frigorifique (12) placé sous la congélation dun échangeur de chaleur (13) permettant de refroidir lespace frigorifique (12) et lamener lespace frigorifique (12) sous la congélation dun dispositif de transport électroconducteur (15) disposé dans lespace frigorifique (12), sur lequel une boisson et un produit alimentaire (XA1) sont montés de roulettes (26) permettant disoler le dispositif de transport (15) de la surface du sol (17), dune surface latérale (18) et dune surface de plafond (19) formant lespace frigorifique (12) dun terminal de source dalimentation électrique (30) raccordé au dispositif de transport (
