Method and apparatus for absorbing heat and preserving fresh produce at a predetermined temperature ensuring optimal conditions of same.

摘要

A method and an apparatus for absorbing heat and preserving fresh products under optimal conditions is described. The products are introduced into a chamber (27) of which at least 70%-80% of the wall surfaces consists of box-shaped interspace panels (14) filled with a thermal capacitance fluid having a freezing temperature with a DELTA T included between -1 and -4 DEG C compared to the refrigeration temperature. Disposed within the panel interspace (22) are circulating circuits (17) containing a brine fluid fed at a temperature having a DELTA T included between -5 and -30 DEG C compared to the refrigeration temperature. The brine circuit (17) is disposed within the panel interspace (22) for distributing the exchange between the brine fluid and the thermal capacitance fluid so as to keep the DELTA T between the maximum and minimum temperature points of the wall under 5 DEG C, preferably not higher than 2 DEG C and particularly not higher than 1 DEG C. <IMAGE>
