Definitions
- the present invention relates to a hermetically sealed refrigerant compressor, which is a hermetically sealed
- Compressor housing has, in the interior of a
- Refrigerant-compressing piston-cylinder unit operates on the cylinder head, a suction muffler (Muffler) is arranged, flows through the refrigerant to the intake valve of the piston-cylinder unit, according to the preamble of claim 1.
- a suction muffler (Muffler) is arranged, flows through the refrigerant to the intake valve of the piston-cylinder unit, according to the preamble of claim 1.
- Such refrigerant compressors have long been known and are mainly used in refrigerators or shelves.
- the annual production quantity is correspondingly high.
- the refrigerant process as such has long been known.
- the refrigerant is heated by energy absorption from the space to be cooled in the evaporator and finally superheated and by means of the refrigerant compressor to a higher
- Refrigerant in the cylinder of the piston-cylinder unit therefore causes as well as the lowering of the temperature during the compression process and the associated
- Discharge temperature a reduction of the required technical work for the compaction process.
- the suction of the refrigerant takes place via a suction pipe coming directly from the evaporator during an intake stroke of the piston-cylinder unit.
- the suction pipe opens in known hermetically sealed refrigerant compressors usually in the hermetically sealed compressor housing, usually in the vicinity of the inlet cross section in the suction muffler, from where the refrigerant flows into the suction muffler and from this directly to the intake valve of the piston-cylinder unit.
- the suction muffler serves primarily to keep the noise level of the refrigerant compressor during the intake as low as possible.
- suction mufflers are usually made of several volumes that communicate with each other, and an inlet cross-section, through which the refrigerant is sucked from the hermetically sealed compressor housing volume in the interior of the suction muffler, and an opening which is close to the intake valve of the piston-cylinder Unit is present.
- the mixture is essentially due to the fact that the intake valve of the piston-cylinder unit per cycle only over a crank angle range of approx. 180 ° is open and therefore only within this time window refrigerant can be sucked into the cylinder of the refrigerant compressor. Thereafter, during the compression cycle, the intake valve is closed.
- the cold refrigerant has an almost constant mass flow, even with the intake valve closed, whereby it flows with the intake valve closed and flows into the compressor housing and the moving piston-cylinder unit and their components cools, which in turn, however, a heating of the Refrigerant itself causes.
- due to the pressure oscillations during the compression phase further flow processes from the compressor housing to the suction muffler and vice versa, whereby an additional mixing is effected.
- Refrigerant compressors the outlet of the intake manifold for the
- Compressor housing can escape.
- one has the Saugrohrende designed so that in this an intermediate tube could be introduced.
- the intermediate tube was surrounded by a spiral spring, which is supported on the one hand at the inlet of the suction tube into the housing and on the other hand on the intermediate tube to achieve the connection of the suction tube to the suction muffler.
- all these known attempts to prevent mixing of the cold refrigerant from the evaporator with the heated refrigerant inside the compressor housing have only caused a reduction in this mixing, but not a complete inhibition.
- the intake silencer can be compensated from the intake manifold and via which the refrigerant located in the intake silencer can again flow out of it into the compressor housing. At the next Ansuagtakt then on the one hand located in the suction muffler or.
- the aim of the present invention is therefore to avoid this disadvantage and to provide a refrigerant compressor of the type mentioned, in which the refrigerant temperature at the beginning of the compression process, and thus necessarily when sucking into the cylinder of the piston-cylinder unit, is kept as low as possible , Wherein the flow losses are kept as far as possible during intake. It is a further object of the present invention to minimize the pressure fluctuations occurring in the interior of the compressor housing and in the suction muffler and to keep the noise level as low as possible when flowing over into the equalizing volume.
- the associated with the creation of the compensation volume due to the flow processes in the compensation volume and in the compressor housing noise be minimized so that it does not disturb the operator disturbing noise, which is particularly important for household refrigerators.
- a slightly larger compensation volume production technology can be made easier.
- the smallest flow cross-section in the compensation volume has a cross-sectional area which corresponds to 1/4 to 3/4 of the cross-sectional area of the intake opening. This ensures that the pressure difference is small, thereby reducing the flow losses and on the other hand, the noise attenuation to the outside is large.
- the cross-section of the compensation volume may not exceed 1, 5 times the
- the characterizing features of claim 5 are provided, according to which the compensating volume is formed by a cross-sectionally substantially U-shaped compensating tube, which at least partially wraps around the suction muffler.
- the characterizing features of claims 6 to 9 describe a preferred embodiment of the connection of intake manifold and inlet cross-section in the suction muffler.
- claims 10 and 11 describe two different embodiments of a hermetically sealed refrigerant compressor, in which the inlet cross section is formed in the suction muffler and the transition from suction muffler in the compensating volume once separated and once coincides.
- the most advantageous embodiment variant is to be selected here, wherein in the case where the inlet cross section in the suction muffler and the transition of suction muffler in the equalization volume coincide another preferred embodiment according to the characterizing features of claims 12 to 14 is provided ,
- This variant has the advantage that a tight connection between the intake manifold and suction muffler is not required.
