(57) The refrigerator comprises at least two compartments (1, 2), one (1) at lower temperature
and the other (2) at higher temperature, and a frigorific circuit (8) including an
evaporator (7) in a position of thermal exchange with the compartment (1) at lower
temperature, a condenser (10) and a compressor (9) that can be disconnected periodically
when the temperature inside the compartment (1) at lower temperature falls below a
pre-set minimum value. A fan (16) determines a forced circulation of air through said
evaporator (7) and inside said compartments (1, 2). There are valve means (22) that,
when the compressor (9) is disactivated, are in a position where they close the compartment
(1) at lower temperature against said forced circulation of air and where they convey
all said air to the compartment (2) at higher temperature.
