Résumé

There is a known phenomenon of refrigeration fluid pulsation in refrigerator compressors. The gas pulsation problem in compressor head cavities and manifolds is important, since pulsation excite structural vibration and travel to the condenser where the major noise source is. It is shown that pulsation has an influence on heat transfer process too. It is shown that when pulsation frequency is similar to resonant frequency of gas the process of heat transfer increases. They used a pulse generator and gas-gas heat exchanger. In refrigeration compressor systems there are heat exchangers, but they are not gas-gas type. There are evaporators and condensers. In both of them there is a phenomenon of refrigeration fluid phase change. This paper is part of the work which investigates an influence of gas pulsation on heat transfer in condensers. A phenomenon of arising pulsation in three most popular compressors in refrigeration is shown: reciprocating, scroll and screw.
