Abstract (en)
A foodstuff refrigerating machine (1) comprising: a boxlike casing (2) which is provided, on the inside, with a large thermo-insulated compartment (3) adapted to contain the foodstuff product to be preserved; an electrically-operated cooling assembly (6) adapted to cool down what is contained inside the thermo-insulated compartment (3); and an electronic control unit (7) that controls the cooling assembly (6); the cooling assembly (6) being provided with a heat pump unit (10) that uses R744 gas as a refrigerant, and with a refrigerated water source (11) that is connected to the high-pressure heat exchanger ( 12) of the heat pump unit (10) so as to circulate, within said heat exchanger, a flow of refrigerated water or other low-temperature heat-transfer liquid capable of removing heat from the refrigerant.
