METHOD FOR BALANCING LUBRICANT LEVELS IN A MULTI-STAGE COMPRESSION UNIT OF A HEAT EXCHANGE SYSTEM, AND HEAT EXCHANGE SYSTEM IMPLEMENTING SUCH A METHOD |
摘要 |
<p>The invention relates to a method for balancing lubricant levels in a multi-stage compression unit (20) of a heat exchange system (1), said compression unit comprising a first compressor (23) and a second compressor (24) arranged in series, the first compressor (23) feeding into the second compressor (24), said balancing method including, during the defrosting of a heat exchanger (5), the transfer of a surplus of lubricant from the first compressor (23) to the second compressor (24) via a balancing line (50), said line comprising first (51) and second (52) valves arranged in parallel, the first valve (51) having a forward bias direction from the first compressor (23) to the second compressor (24), the second valve (52) having a forward bias direction from the first compressor (23) to the second compressor (24), and a reverse bias direction from the second compressor (24) to the first compressor (23).</p> |
