Definitions

  • the present invention relates to a cooling device wherein the condenser and the compressor are cooled effectively.
  • the compressor and the condenser In cooling devices, for example refrigerators, the compressor and the condenser, particularly the coil type condenser that is preferred for taking up less space, operates in a compartment that is generally situated at the lower portion of the body. Air is blown over the compressor and the condenser for removing heat by forced circulation and aiming to increase efficiency.
  • a fan is operated in between or on one side of the compressor and the condenser to cause cooling and the air aspirated by means of the fan from the exterior environment is generally passed over either the condenser and directed to the compressor or passed over the compressor and directed to the condenser.
  • a cross flow type fan is disposed between the compressor and the condenser.
  • the air aspirated from the outer environment is passed over the condenser and directed to the compressor.
  • the air suction and discharge openings By means of the air suction and discharge openings the air aspirated from the outer environment and passed over the condenser and the compressor is discharged to the environment.
  • the aim of the present invention is the realization of a cooling device wherein the condenser and the compressor are cooled effectively by regulating the flow of air.
  • the compressor and the coil condenser operate in the machine room preferably situated at the lower portion of the body called the cabin &r end region.
  • Air is aspirated from the outer surrounding by means of a Ian and a suction channel situated in the machine room, an air distributor is used, to which the suction channel is connected, that surrounds the Ian for safeguarding and provides the air aspirated from the outer environment to be directed partially over the compressor and partially over the condenser.
  • the flow rate of the air sent over the compressor and the condenser is adjusted by a flow separator such as a valve or the like that is disposed in the air distributor.
  • the desired amount of air aspirated from the outer environment is directed towards the compressor or the desired amount to the condenser by the flow separator, thus providing to send a larger amount of air over either the compressor or condenser, whichever requires more cooling in terms of efficiency.
  • the air distributor is disposed on the left side or right side of the compressor and the condenser and the blowing orifices are arranged on the side of the air distributor lacing the compressor and the condenser, providing to blow air in the same direction and separately towards the compressor and the condenser.
  • the air distributor is disposed in between the compressor and the condenser, and the blowing orifices are arranged on the left and right side of the air distributor, providing to blow air separately towards the compressor and the condenser that are situated at opposite sides of one another.
  • Rgure 1 - is the schematic top view of the cabin lar end machine room of a cooling device.
  • Rgure 2 - is the perspective view of the cabin &r end machine room of a cooling device.
  • Rgure 3 - is the front schematic view of the cabin &r end machine room of a cooling device in another embodiment of the present invention.
  • Rgure 4 - is the top schematic view of the cabin &r end machine room of a cooling device in another embodiment of the present invention.
  • the cooling device (1) preferably a refrigerator, comprises a compressor (2) for providing the refrigerant cycle, a condenser (3) that condenses the refrigerant, and a machine room (4) wherein the compressor (2) and the condenser (3) are disposed, and a &n (5) situated in the machine room (4) that cools the compressor (2) and the condenser (3) by blowing air thereupon.
  • the cooling device (1) of the present invention comprises a suction channel (6) through which air is aspirated from the outer environment by the &n (5) and an air distributor (7) to which the suction channel (6) is connected, safeguarding the &n (5) by encircling peripherally thereof, providing some amount of the air aspirated from the outside received through the suction channel (6) to be directed over the compressor (2) and some amount over the condenser (3).
  • the cooling device (1) comprises one or more flow separators (9) such as a valve, preferably disposed in the air distributor (7) that regulates the flow rate of the air sent to the compressor (2) and the condenser (3).
  • the desired amount of the air aspirated from the outer environment by the Ian (5) is directed towards the compressor (2) or the desired amount to the condenser (3) by means of the flow separator (9), thus providing to send a larger amount of air over either the compressor (2) or condenser (3), whichever requires more cooling in terms of efficiency.
  • the flow separators (9) are moved according to the data received from sensors such as a heat sensor, providing to regulate the flow rate of the air blown over the compressor (2) and the condenser (3).
  • the cooling device (1) furthermore comprises a compressor blowing orifice (8) situated on the air distributor (7) that provides the air aspirated by the Ian (5) from the outer environment to be blown over the compressor (2) and a condenser blowing orifice (108) that provides the air aspirated by the Ian (5) from the outside to be blown over the condenser (3).
  • the air aspirated from the outer environment by means of the suction channel (6) as the Ian (5) operates fills into the inner volume of the air distributor (7) whereby some portion thereof, without intermixing with the air already present in the machine room (4), being activated by the fan (5), is directed directly over the compressor (2) and some portion thereof is directed directly towards the condenser (3) and is blown through the blowing orifices (8, 108) over the compressor (2) and the condenser (3).
  • the air aspirated into the air distributor (7) by the fan (5) is adjusted by the flow separator (9) that sends a greater amount of air over the compressor (2) or the condenser (3), whichever is heated far more and in need of more cooling.
  • a radial type fan (5) is utilized in the cooling device (1) of the present invention.
  • radial type fans (5) a lesser number of revolutions is sufficient for providing the desired air flow rate than the axial type ones and thus the noise level in the machine room (4) resulting from air flow can be reduced.
  • the air distributor (7) is disposed on the left or right side of the compressor (2) and the condenser (3) and the blowing orifices (8, 108) are arranged on the side of the air distributor (7) facing the compressor (2) and the condenser (3).
  • the blowing orifices (8, 108) allow air to be blown from the air distributor (7) towards the compressor (2) and the condenser (3) in the same direction but separately.
  • the air distributor (7) is disposed in between the compressor (2) and the condenser (3) and the blowing orifices (8, 108) are arranged on the right and left side of the air distributor (7) thus allowing air to be blown separately to the compressor (2) and the condenser (3) that are disposed oppositely to one another.
  • the compressor (2) and the condenser (3) are cooled effectively and a significant increase in the coefficient of performance of the compressor (2) is maintained, the thermal efficiency of the condenser (3) is increased, the compressor (2) and the condenser (3) are cooled separately according to their cooling requirements and the noise level is reduced.

Abstract

L'invention concerne un mécanisme de réfrigération (1) dans lequel le compresseur (2) et le condenseur à serpentin (3) fonctionnent dans la salle des machines (4) située de préférence dans la partie basse du corps appelée l'extrémité éloignée de la cabine. De l'air est aspiré de l'environnement extérieur dans la salle des machines (4) grâce à un ventilateur (5) situé dans la salle des machines (4) et une conduite d'aspiration (6). Un distributeur d'air (7) est utilisé pour envoyer l'air partiellement sur le compresseur (2) et partiellement sur le condenseur (3).
