Abstract

A process for cooling CO2 in a refrigerator system comprising a circulation step of CO2 into circuits 10, 20 of at least one finned battery heat exchanger 1. Exchanger 1 is divided into a first and a second cooling section S1 and S2, each comprised of a group of circuits 10,20 connected in parallel. The two sections S1 and S2 are connected to one another in series. The exchanger is sized so that the second cooling section S2 has a flow section comprised between 20% and 40% of the total flow section offered by all the circuits as a whole. Concurrently with the circulation step, a ventilation step is envisaged, wherein a first air flow A1 is made to pass through the first cooling section S1 and a second air flow A2 is made to pass through the second cooling section S2. Concurrently with the ventilation step, an adiabatic saturation step is envisaged, wherein the second air flow A2 is humidified at least up to saturation before flowing through the second cooling section S2. Concurrently with the circulation step, the process envisages a first cooling step, wherein the CO2 is cooled starting from an initial temperature T1 up to an intermediate temperature T2 at the first cooling section S1 by the effect of a thermal exchange with the first air flow A1 in the ambient conditions of temperature and of relative humidity, and a second cooling step, wherein the CO2 is cooled from the intermediate temperature T2 up to a final temperature T3 at the second cooling section S2 by the effect of a thermal exchange with the second air flow A2.
A further object of the present invention is a finned battery heat exchanger for carrying out such process.
