EL EQUIPO DE ENFRIAMIENTO OPERA CON AIRE AMBIENTE Y UN AGENTE FRIO, SOLIDO A TEMPERATURA ATMOSFERICA, ALOJADO EN UNA TORRE DE ENFRIAMIENTO (100), CON ENTRADAS DE AIRE Y CIERRES (11) DE LAS MISMAS, Y UNA GRAN SUPERFICIE DE INTERCAMBIO DE CALOR (3), DISPUESTOS DENTRO DE LA TORRE DE ENFRIAMIENTO. LAS ENTRADAS DE AIRE ESTAN DIVIDIDAS DENTRO DE GRUPOS O SECTORES CONECTADOS DE FORMA PARALELA. EL AGENTE ES ENFRIADO POR UNA CORRIENTE DE AIRE QUE ATRAVIESA LA GRAN SUPERFICIE DE INTERCAMBIO DE CALOR (3). SE PRODUCE UN PRECALENTAMIENTO ANTES DEL INTERCAMBIADOR (20) EN CADA SECTOR DE LA SUPERFICIE DE INTERCAMBIO (3), LLEVANDOSE EN PARALELO DICHO INTERCAMBIO. In a cooling apparatus operated by ambient air and an agent to be cooled which can have solid state at atmospherical temperatures, a housing such as a cooling tower (100) with air inlets and air closure means (11) at the air inlets and great surface heat exchangers (3) arranged within the cooling tower (100) at its air inlets and divided into groups or sectors being in parallel connection are provided, with which the agent is cooled by the air streaming through the great surface heat exchangers (3). According to the invention, at least one pre-heating heat exchanger (20) is arranged in the air space (29) of each sector of the great surface heat exchangers (3), and the pre-heating heat exchangers (20) are in parallel connection with the great surface heat exchangers (3) of each sector.
