system and method for the production of cold and for regulating the temperature and the heat exchange device for this system

摘要

The invention refers to a thermal installation (1) comprising a closed circuit (2), wherein a working fluid carries out a thermodynamic cycle, comprising a plurality of thermal user points (5), at which said working fluid is at a temperature suitable for the heat exchange with at least one unit (9) for adjusting air temperature of an environment (A) and at least one of a deep-frozen or frozen food conservation unit (7) and a fresh food conservation unit (8).;The invention also refers to a heat exchange device (4) that can be used in the aforementioned thermal installation (1) and to a thermodynamic process for producing cold and adjusting air temperature of environment (A) that can be actuated through such an installation.
