<p>Method and apparatus of discharging non-condensable gases from the circuit of a compression refrigeration machine, wherein a part of the circuit (4) through which there is no flow is indirectly cooled by a smaller secondary refrigeration machine (7, 8, 9, 10, V2) in order to condense the condensable refrigerant vapour in that part (4) and thus to lower the content of non-condensable gases to be discharged in that part (4), whereby the value of the suction pressure (Pc) of the refrigerant circuit of the secondary refrigerating machine (7, 8, 9,10, V2) is used for automatically starting and stopping the discharge of non-condensable gases.</p> |
