Abstract

Le procédé selon l'invention est caractérisé en ce que lesdites batteries sont alimentées respectivement par au moins un circuit frigorifique à détente directe et par un circuit frigorifique hydraulique en contact avec l'air à climatiser, la puissance desdits circuits frigorifiques étant sensiblement égale, et on utilise le circuit frigorifique hydraulique pour compléter la puissance d'un ou plusieurs circuits frigorifique à détente directe en service afin d'obtenir la puissance désirée. The method according to the invention is characterized in that said batteries are powered respectively by at least one circuit direct expansion refrigeration and a refrigeration circuit hydraulic in contact with the air to be conditioned, the power of said refrigeration circuits being substantially equal, and the hydraulic refrigeration circuit to supplement the power of one or several direct expansion refrigeration circuits in service to to obtain the desired power.
