Definitions
- the present invention relates to a compressor wherein the performance is improved.
- a suction muffler made of plastic material is used for attenuating the noise resulting from the refrigerant fluid and the refrigerant fluid with decreased temperature and pressure received from the evaporator is delivered to the suction muffler.
- the refrigerant fluid aspirated by the suction muffler disposed inside the compressor casing is conveyed to the cylinder volume and is compressed here by the piston to partake in the refrigeration cycle.
- semi-direct suction method is used in compressors for the aim of cooling the refrigerant received into the cylinder volume.
- the suction muffler inlet and the inlet pipe leak-proofingly entering the casing are opposite to but not connected to each other. Since the suction muffler inlet is not directly connected to the inlet pipe, the refrigerant fluid sucked into the casing enters into the suction muffler with increased temperature due to the heat in the casing. Since the temperature of the refrigerant fluid increases, the volumetric efficiency of the compressor hence the coefficient of performance (COP) decreases.
- COP coefficient of performance
- refrigerant fluid is received into the suction muffler after entering the casing, it is affected by the heat in the casing and the previously above mentioned problem arises.
- connection pipe is described that is disposed between the muffler inlet and the intake pipe, for delivering the refrigerant fluid to the suction muffler.
- the aim of the present invention is the realization of a compressor wherein the performance is improved.
- the compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a muffler pipe that by passing through an opening on the casing opens into the inlet pipe, whereof the end is connected to the opening, such that a clearance is left there between.
- the muffler pipe is disposed inside the inlet pipe without being in contact PatXML 3/6 BB1546-7.724
- the muffler pipe is configured frusto-conically.
- the top angle is preferably 30 degrees maximum.
- the muffler pipe gets wider from the casing towards the suction muffler. By means of this configuration, the compressor noise power level is diminished.
- the inlet of the suction muffler extends outside the casing by the muffler pipe and is inserted into the inlet pipe. Accordingly, the greater portion of the refrigerant fluid entering into the suction muffler is prevented from being received through the casing. Consequently, compressor efficiency is increased by maintaining the temperature of the refrigerant fluid entering the suction muffler to be lower.
- a lesser amount of lubricant is received into the suction muffler than the current semi-direct suction compressors. Besides, since the muffler pipe and the inlet pipe are not in contact with each other, vibrations and noise generated by the vibrations are also prevented.
- Figure 1 - is the schematic view of the compressor of the present invention.
- the compressor (1) comprises a casing (2), a suction muffler (5) disposed inside the casing (2) that attenuates the noise resulting from the refrigerant fluid, an inlet pipe (4) that carries the refrigerant fluid delivered from the PatXML 4/6 BB1546-7.724
- the compressor (1) furthermore comprises a muffler pipe (6), with one end opening into the suction muffler (5), the other end extending outwards of the casing (2) by passing through the opening (3) and opening into the inlet pipe (4) so as to have a clearance there between.
- the muffler pipe (6) is extended up to inside of the inlet pipe (4) from outside the casing (2) and almost all of the refrigerant fluid sucked by the compressor (1) is directly received into the suction muffler (5) without entering into the casing (2).
- the inlet of the suction muffler (5) is extended up to the inside of the inlet pipe (4).
- the muffler pipe (6) is configured to be preferably frusto-conical, getting narrower from the suction muffler (5) towards the inlet pipe (4).
- apex (X) of the muffler pipe (6) is 30 degrees maximum.
- the end of the muffler pipe (6) inserted into the inlet pipe (4) is narrower than the end thereof opening into the suction muffler (5).
- the muffler pipe (6) and the inlet pipe (4) are disposed one inside the other coaxially.
- the refrigerant fluid flowing in the inlet pipe (4) can be directly received into the suction muffler (5) by passing through the muffler pipe (6) without confronting with any obstruction.
- the portion of the inlet pipe (4) wherein the muffler pipe (6) is inserted is configured frusto-conically with a maximum apex (Y) of 30 degrees.
- the compressor (1) efficiency is increased by the refrigerant fluid received into the suction muffler (5) from the refrigeration cycle being cooler than the refrigerant fluid received inside the casing (2). Besides, the amount of lubricant delivered into the suction muffler (5) from the refrigeration cycle is decreased. On the other hand, the vibrations in the refrigeration cycle and noise due to vibrations are also reduced.
