<p>A combined refrigerating and vacuum-generating apparatus is described, comprising:
- a refrigerating circuit comprising a compressor (1) for compressing a refrigerating fluid, a condenser (2) for condensing the refrigerating fluid coming from the compressor (1), an expansion unit (5) for causing a pressure drop in the refrigerating fluid, and at least one evaporator (6) for the evaporation of the refrigerating fluid, said refrigerating circuit it being divided into a high-pressure side (AP) and a low-pressure side (BP);
- means (10, 11, 12) for generating vacuum inside a container (13). The invention is characterized in that said vacuum-generating means (10, 11, 12) are connected to the low-pressure side (BP) of the refrigerating circuit, so as to exploit the pressure differential being present within said refrigerating circuit in order to generate vacuum inside said container (13).</p> |
