1. A removable food support element in a refrigerator, for example a shelf or drawer, comprising a body to be positioned on supports present on opposing walls of a refrigerator compartment, and, associated with the body of the element, setting means enabling an internal temperature of the refrigerator compartment to be set and the set temperature information to be transferred to a control means for a refrigerator refrigeration circuit, the setting means comprising a resonant circuit arranged to generate a signal which can be modified on the basis of the set temperature, or of a set temperature range, by modifying at least one electrical characteristic of the circuit, the resonant circuit comprising a plurality of capacitors of different capacitances selectively connectable to an inductor cooperating with an induction element associated with the control means and fixed to the refrigerator. 2. An element as claimed in claim 1, wherein the resonant circuit is of passive type, the induction element being connected to an oscillating circuit connected to the control means, and receiving an electrical signal from said circuit. 3. An element as claimed in claim 1, wherein the resonance circuit is self-powered. 4. An element as claimed in claim 1, comprising operating means operationally cooperating with the resonant circuit to select a capacitor of capacitance chosen on the basis of the desired temperature or of the desired temperature range in correspondence with the element. 5. An element as claimed in claim 4, wherein the operating means are a selector movable on a face, preferably the front face, of the element. 6. An element as claimed in claim 4, wherein the operating means are a plurality of pushbuttons operationally connected to the various capacitors. 7. An element as claimed in claim 4, wherein the operating means act on switches arranged to connect different capacitors to the inductor. 8. An element as claimed in claim 1, wherein the electrical circuit comprises radio-frequency signal generating means cooperating with receiving counter-means connected to the control means. 9. A removable food support element in a refrigerator, for example a shelf or drawer, comprising a body to be positioned on supports present on opposing walls of a refrigerator compartment, and, associated with the body of the element, means for measuring the temperature present in the refrigerator compartment, setting means comprising a resonant circuit and configured to enable an internal temperature of the refrigerator compartment to be set and the set temperature information to be transferred to a control means for a refrigerator circuit, the measurement means comprising capacitors of the resonant circuit.
