Maîtrise de la consommation électrique des laveurs-désinfecteurs, par optimisation du couple température/durée.

Introduction: Resterilizable medical devices go through a washing process, where the temperature/duration pairing usually comply with an A0=3000 factor. In the context of energy tensions, we aimed to determine the most energy-efficient pairing. Method: We modeled the curve corresponding to the equation controlling the A0 = 3000 factor, then select the pairs to be measured, corresponding to the curve's inflection points. We installed a multimeter to measure the power consumption of our washer. Power consumption was computer-modeled, and the lowest point of the curve was determined. Results: The power consumption of our washer follows a polynomial curve of equation 32.043.x² - 5875.3.x + 276555 (R=0.993). The lowest point on the curve corresponds to the 92°/190s couple, with lower power consumption than the 93°/180 s couple currently used in service (p < 0.05). With over 1990 cycles per year and a cost reduction of almost 30%, the potential saving would be €915. Discussion: We were able to determine the most economical pairing in terms of power consumption on our washer. Further measurements are to be carried out on our other washers, to determine whether the results observed are also applicable to them. [ABSTRACT FROM AUTHOR]
