Definitions

  • This invention relates to a compressor comprising a suction muffler, which minimizes the noise generated during circulation and heating up of the fluid in the re ⁇ frigeration cycle.
  • cooling is generally achieved by a refrigerant fluid, which circulates in a circuit comprising a condenser that transfers heat o the outer medium, an evaporator that absorbs heat, and a compressor.
  • the condenser receives the high pressure fluid at the outlet of the compressor, and the fluid, depressurized through the capillary tube positioned at the outlet of the condenser, is transferred from the evaporator to the suction inlet of the compressor.
  • suction mufflers are used which allow the refrigerant fluid to reach the cylinder section without heating and avoid the noise that may be generated by the refrigerant fluid.
  • the suction muffler is generally made of plastic and positioned on the cylinder head or between the cylinder head and the valve table. The sucked in refrigerant fluid reaches the cylinder section through the suction muffler, which has a portion in the cylinder head composing the suction manifold.
  • the object of the present invention is to design a compressor comprising a suction muffler which minimizes noise, heat transfer and depressurization, and provides the oil contained within the refrigerant fluid in the cooling cycle to be separated from the re ⁇ frigerant fluid and collected.
  • Figure 1- is the sectional view of a compressor comprising a suction muffler fixed inside a shell.
  • Figure 2 - is the sectional view of a compressor comprising a suction muffler fixed outside a shell.
  • Figure 3 - is the schematic side view of a suction muffler comprising a tube, which is connected to a suction chamber.
  • Figure 4 - is the perspective view of the AA section of a suction muffler comprising only one tube.
  • Figure 5 - is the schematic view of a suction muffler comprising two tubes placed one inside the other.
  • Figure 6 - is the perspective view of the AA section of a suction muffler comprising two tubes.
  • the compressor (1) comprises a shell (7) inside which components are assembled and are protected, a cylinder (2) inside the shell (7) which provides pumping of the re ⁇ frigerant fluid, a cylinder head (3) positioned above the cylinder (2) for circulating the sucked and pumped refrigerant fluid, a valve table (5) onto which the cylinder head (3) is positioned, a suction muffler (4) fixed on the shell (7) which by lowering the acoustic energy of the refrigerant fluid prevents the noise that may be generated by the refrigerant fluid, a suction chamber (15) attached to the cylinder head (3) which provides the unheated delivery of the refrigerant fluid with reduced acoustic energy to the cylinder (2), and a pipe (10) connecting the suction muffler (4) and the suction chamber (15), allowing passage of the refrigerant fluid, which is flexible, resistant to heat and pressure, and made of a material unaffected by substances like refrigerant fluid and oil.
  • the suction muffler (4) comprises a muffler exit orifice (6) to which the pipe (10) is connected, at least one muffler chamber (11) inside which the acoustic energy of the refrigerant fluid is reduced, a tube (9) through which the refrigerant fluid is delivered, inserted into the muffler chamber (11), with one end outside the shell (7) and the other end inserted inside the shell so as to go through and open outside the suction chamber (11), and a suction inlet (8) through which a tube (9) is inserted, encompassing all.
  • the tube (9) comprises a tube outlet (12) which opens into the muffler chamber
  • the refrigerant fluid received from outside the compressor (1) goes through the tube (9), enters the suction muffler (4) by means of the tube outlet (12) and out of the suction muffler (4) by means of the hole (13) thereby diffusing into the inner enclosure of the shell (7).
  • the refrigerant fluid flowing from the tube outlet (12) reaches first the pipe (10) by means of the suction exit orifice (6) and then the suction chamber (15).
  • the suction muffler (4) comprises at least two tubes (9) placed one inside the other, which transfer the refrigerant fluid to one another, lowering the noise power level without increasing depressurizing.
  • the suction muffler (4) comprises more than one tube (9), which receive the refrigerant fluid from one flow pipe and deliver to the suction chamber (11) each independently from the other.
  • the suction muffler (4) comprises more than one tube (9), which receive the refrigerant fluid from one flow pipe and deliver to the suction chamber (11) each independently from the other.
  • the flow of the refrigerant fluid is improved by balancing the pressure between the shell (7), the muffler chamber (11) and the tube (9), and noise is minimized by increasing the capacity of the compressor
