Abrégé

The invention relates to a method for regulating the temperature and hygrometry of internal air inside a refrigeration chamber (3) according to a temperature set value and a hygrometry set value determined by a user, the temperature and hygrometry being varied by means of the circulation of a refrigerant through a refrigeration loop (2) having a compressor (4), a condenser (5) and an evaporator (7), the regulation being performed by an automaton (11) comparing the measured temperature and hygrometry of the internal air with the temperature and hygrometry set values. According to the invention, when the temperature of the internal air is above the temperature set value, the automaton (11) activates a cold production procedure during which: (i) if the hygrometry of the internal air is below the hygrometry set value, the automaton (11) adjusts downward an air flow set value of an internal fan (9) adapted to produce an air flow through the evaporator (7) and adjusts upward an operating set value of the motor of the compressor (4) such as to increase the temperature of the refrigerant in the evaporator (7) and, consequently, increase the hygrometry of the internal air, and, if the hygrometry of the internal air is above the hygrometry set value, the automaton (11) adjusts upward the air flow set value of the internal fan (9) and adjusts downward the operating set value of the motor of the compressor (4) such as to reduce the temperature of the refrigerant in the evaporator (7) and, consequently, reduce the hygrometry of the internal air, and if the hygrometry of the internal air is equal to the hygrometry set value, the automaton (11) maintains the air flow set value of the internal fan (11) and the operating set value of the motor of the compressor (4) as they are; and (ii) the automaton (11) activates an external fan (8) adapted to produce an air flow through the condenser (5) at an air flow set value such as to maintain the pressure of the refrigerant leaving the condenser (5) constant during the entire duration of the cold production procedures of the regulation method, and, when the temperature of the internal air is less than or equal to the temperature set value, the automaton (11) activates a procedure for stopping cold production, and if the hygrometry of the internal air is below the hygrometry set value, the automaton (11) adjusts the air flow set value of the internal fan (9), and, if the hygrometry of the internal air is greater than or equal to the hygrometry set value, the automaton (11) stops the internal fan (9).
