Claim 20:
21. A method for operating a refrigeration apparatus according to claim 1, comprising:
a) circulating said coolant along said main branch (M) of said closed circuit (C);
b) circulating said fraction (X1) of flow rate of said coolant along said secondary economizer branch of said closed circuit; and
c) driving the operations of said reciprocating compressor;
wherein said step c) comprises the step c1) of diverting a portion (X2) of said fraction (X1) of coolant coming from said secondary economizer branch in order to drive the displacement of said piston of said reciprocating compressor and compress the coolant coming from said evaporator contained in said cylinder, and the step c2) of reintroducing said portion (X2) of fraction of cooling liquid into said secondary economizer branch during the displacement of said piston in the step of suctioning the coolant coming from said evaporator, for the outflow of said portion (X2) of fraction of coolant through said outlet section of said secondary economizer branch, wherein said outlet section of said secondary economizer branch is arranged downstream of said reciprocating compressor.
