<p>A refrigerant recovery and recharge device and a method to operate the refrigerant recovery and recharge device is disclosed. The refrigerant recovery and recharge device (10) is adapted to be connected to refrigeration equipment (12). The device (10) comprises at least a valve block (14), an accumulator (16), a compressor (18) and a tank (20). The device (10) also comprises a first flow path (22) adapted to recover refrigerant from the refrigeration equipment (12) and a second flow path (24) adapted to recharge refrigerant to the refrigeration equipment (12). The device (10) is characterized by comprising a third flow (path 26) adapted to redirect refrigerant from tank (20) to accumulator 16; at least one valve (28) located in the third flow path (26) adapted to be actuated in a manner that allows redirection of refrigerant from tank (20) to accumulator (16); and a control unit (32) adapted to control actuation of at least one valve (28).</p> |
