Description

  The present invention relates to a refrigeration apparatus including a covering member that covers a compressor.

  Conventionally, a refrigeration apparatus including a covering member that covers a compressor arranged inside a casing is known. This covering member is provided for the purpose of heat insulation and sound insulation. In this type of refrigeration apparatus, when the compressor is insulated, it is possible to suppress a decrease in the amount of heat of refrigerant discharged from the compressor due to heat radiation from the surface of the compressor. Further, when the compressor is soundproofed, the noise of the compressor is suppressed.

  By the way, for the covering member covering the compressor, a heat insulating material mainly for heat insulation, a sound absorbing material mainly for sound absorption, and a sound insulating material mainly for sound insulation are used according to the purpose. Among these, the heat insulating material generally has a characteristic that it has a certain level of sound absorption, but is poor in sound insulation. For this reason, in order to acquire a high effect about both heat insulation and sound insulation of a compressor by providing a covering member in a compressor, it becomes indispensable to combine a heat absorbing material and a sound insulation material with a heat insulating material. In addition, since the strength of the covering member is increased by adopting such a structure, when covering the compressor with the covering member, the covering member is covered with the compressor and fixed in a state where it is self-supporting on the bottom plate of the casing. ing.

  However, when the covering member is brought into contact with the bottom plate of the casing, vibration generated by driving the compressor is directly transmitted to the covering member via the bottom plate of the casing. As described above, when the vibration of the compressor is propagated to the covering member, the vibration is amplified in the covering member to cause noise. Therefore, it is necessary to take measures against noise.

  The present invention has been made in view of such a point, and the object thereof is a refrigeration apparatus provided with a covering member for a compressor in order to obtain both effects of heat insulation and sound insulation of the compressor. It is to reduce the noise caused by the vibration by suppressing the propagation of the vibration of the compressor to the covering member.

  In order to achieve the above-described object, the present invention supports the covering member in a suspended position so that the vibration of the compressor is not propagated to the covering member via the bottom plate of the casing.

−Structure of compressor and accumulator−
Next, the structure of the compressor (30) and the accumulator (31) will be described. As shown in FIG. 2, the compressor (30) includes a compression mechanism (30b) that compresses the refrigerant, an electric motor (30a) that drives the compression mechanism (30b), a compression mechanism (30b), and an electric motor (30a) And a storage container (28).

  The storage container (28) is formed in a cylindrical container shape whose both ends are closed. For example, three plate-like members (29) are connected to the bottom surface of the storage container (28). Each plate-like member (29) has an insertion hole (29a) through which a pin member (39) described later is inserted. These plate-like members (29) are arranged at equal intervals in the circumferential direction of the container (28). The plate-like member (29) and the pin member (39) play a role of holding the position of the compressor (30) against the vibration of the storage container (28) during the operation of the compressor (30).

  The accumulator (31) is configured as a cylindrical container closed at both ends. The outer diameter and height of the accumulator (31) are set smaller than the container (28) of the compressor (30). The accumulator (31) is connected to the compressor via the mounting member (40) with its axial direction being substantially parallel to the axial direction of the container (28) of the compressor (30) and close to the compressor (30). (30) is attached.

  A discharge pipe (21) is connected to the upper surface of the container (28) of the compressor (30). A suction pipe (22) is connected to a lower position on the side of the storage container (28). The suction pipe (22) extends in the horizontal direction and then bends vertically upward and is connected to the bottom surface of the accumulator (31). A connection pipe (23) is connected to the upper surface of the accumulator (31).

  Three pin members (39) project from the upper surface of the bottom plate (43) of the casing (35) of the outdoor unit (11). The pin member (39) is disposed at a position corresponding to the apex of the equilateral triangle, corresponding to the plate-like member (29). The compressor (30) and the accumulator (31) are integrally installed while the pin member (39) is inserted through the insertion hole (29a) of the plate-like member (29).

  The periphery of the compressor (30) and the accumulator (31) is covered with a covering member (25). The inner peripheral shape of the covering member (25) is slightly larger than the shape in which the compressor (30) and the accumulator (31) are integrally projected in the vertical direction. When the covering member (25) is installed, the compressor (30) and the accumulator (31) are collectively surrounded by the covering member (25). In this state, an air layer (19) is formed between the covering member (25) and the compressor (30) or between the covering member (25) and the accumulator (31).

-Structure of the covering member-
Next, the structure of the covering member (25) will be described. As shown in FIG. 2, the covering member (25) includes a heat insulating layer (17) formed of a heat insulating material, a sound absorbing layer (18) formed of a sound absorbing material, and a sound insulating layer (16 ). The covering member (25) has a three-layer structure including a heat insulating layer (17), a sound absorbing layer (18), and a sound insulating layer (16).

  The heat insulating material constituting the heat insulating layer (17) is formed of a vacuum heat insulating material. In addition, you may use materials (for example, urethane) other than a vacuum heat insulating material for a heat insulating material. As the heat insulating material, a material having no air permeability or a material having low air permeability is suitable. On the other hand, the sound absorbing material is made of glass wool. In addition, you may use materials (for example, felt, rock wool) other than glass wool as a sound-absorbing material. As the sound absorbing material, a material having good air permeability is suitable. The sound insulating material constituting the sound insulating layer (16) is formed of a member having a relatively high density such as rubber.

  The covering member (25) includes a side wall member (26) that covers the sides of the compressor (30) and the accumulator (31), and a ceiling member (27) that covers the upper side of the compressor (30) and the accumulator (31). It is composed of

  The ceiling member (27) is formed in a disc shape. The ceiling member (27) is formed with a first insertion hole (27a) through which the discharge pipe (21) is inserted and a second insertion hole (27b) through which the connection pipe (23) is inserted.

  In Embodiment 1, as described above, when the covering member (25) is installed, an air layer (19) is formed between the covering member (25) and the compressor (30). For this reason, since the vibration of the compressor (30) is not directly propagated to the covering member (25), compared with the case where the vibration of the compressor (30) is directly propagated to the covering member (25). The vibration propagated to the covering member (25) is significantly reduced. Therefore, since it is not necessary to secure the thickness of the sound absorbing layer (18) in order to attenuate the transmitted vibration, the thickness of the sound absorbing layer (18) is reduced.

  Here, the said covering member (25) is supported in the suspended position via the supporting member (46) provided in the partition plate (44) which partitions off the inside of a casing (35). Specifically, the support member (46) is a member provided in the vicinity of the upper end of the covering member (25) in the partition plate (44) and extending in the horizontal direction, and the side wall member (26) of the covering member (25). The upper end of the is supported. At this time, the lower end of the side wall member (26) of the covering member (25) is separated from the bottom plate (43) of the casing (35), and the covering member (25) is supported in a suspended posture.

  With such a configuration, it is possible to suppress the vibration of the compressor (30) from being directly transmitted to the covering member (25) via the bottom plate (43) of the casing (35). Since the vibration propagated to is greatly reduced, it is possible to suppress the vibration from being amplified in the covering member (25), which is advantageous in reducing the generation of noise due to the vibration.

  Further, by separating the support member (46) from the bottom plate (43) of the casing (35) where the vibration of the compressor (30) is most significantly propagated, the vibration of the compressor (30) is supported by the support member (46). Propagation through the covering member (25) can be suppressed.

  Furthermore, by providing a support member (46) on the partition plate (44) that partitions the inside of the casing (35), the compressor (30) can be connected to the partition plate (44) via the bottom plate (43) of the casing (35). Since the propagated vibration is attenuated while being propagated by the partition plate (44), the vibration of the compressor (30) is propagated to the covering member (25) via the support member (46). Furthermore, it can suppress effectively.

  In the first embodiment, the support member (46) is provided on the partition plate (44) that partitions the inside of the casing (35). However, the present invention is not limited to this configuration. You may make it provide a supporting member (46) in a side wall board (45). Similarly, in this case, since the vibration propagated from the compressor (30) to the side wall plate (45) through the bottom plate (43) of the casing (35) is attenuated in the side wall plate (45), the compressor ( It is possible to effectively suppress the vibration of 30) from being propagated to the covering member (25) through the support member (46).

  On the upper surface of the bottom plate (43) of the casing (35), the arrangement position of the covering member (25) in the casing (35) is determined by contacting the peripheral edge of the lower end portion of the side wall member (26) of the covering member (25). A guide member (41) is provided. Specifically, when the covering member (25) swings in the width direction, the position of the covering member (25) is regulated by coming into contact with the guide member (41). For this reason, when the covering member (25) is supported in a suspended posture, even if the lower end portion of the covering member (25) tries to swing in the width direction, the swing is restricted by the guide member (41), and the casing ( 35) The position of the covering member (25) can be determined with certainty.

  When the covering member (25) swings in the vertical direction, the periphery of the lower end portion of the covering member (25) slides along the contact surface of the guide member (41). Therefore, for example, even if the vibration of the compressor (30) is propagated to the guide member (41) via the bottom plate (43) of the casing (35), the vibration is propagated to the covering member (25). It is possible to suppress noise and reduce the generation of noise.

  Specifically, the vibration that causes the generation of noise is often caused by the vibration in the thickness direction of the bottom plate (43) of the casing (35). As in the present invention, the covering member (25) is suspended in a suspended posture. It is preferable that the vibration in the thickness direction of the bottom plate (43) is not propagated to the covering member (25) so that it hardly affects the generation of noise.

  In the refrigeration apparatus (10) according to the first embodiment, sound generated by driving the compressor (30) first passes through the air layer (19). In the air layer (19), a part of sound energy is converted into heat energy, so that the sound is absorbed. Subsequently, in the sound absorbing layer (18), part of the sound energy that has passed through the air layer (19) is converted into the heat energy of the sound absorbing material and the air in the air gap, thereby absorbing the sound. In the heat insulating layer (17), heat energy is insulated. The sound insulation layer (16) is insulated by reflecting a part of the sound that has passed through the sound absorption layer (18) and the heat insulation layer (17).

  Thus, the sound generated by driving the compressor (30) is absorbed by the air layer (19) and the sound absorbing layer (18), and is sound-insulated by the sound insulating layer (16). Further, the heat energy generated at this time is insulated by the heat insulating layer (17). Therefore, the sound emitted from the compressor (30) is greatly reduced before it propagates outside the covering member (25). The compressor (30) is covered with a covering member (25) having a heat insulating layer (17). For this reason, since it is suppressed that the calorie | heat amount of the discharge refrigerant | coolant of a compressor (30) reduces by the heat radiation from the surface of a compressor (30), operating efficiency can be improved.

  As described above, according to the refrigeration apparatus (10) according to the first embodiment, the supporting member (46) causes the lower end of the covering member (25) to be suspended from the bottom plate of the casing (35) in a suspended position ( 25) is supported, it is possible to suppress the vibration of the compressor (30) from being directly transmitted to the covering member (25) via the bottom plate (43) of the casing (35). Since the vibration propagated to 25) is significantly reduced, it is possible to suppress the vibration from being amplified in the covering member (25), which is advantageous in reducing the generation of noise due to the vibration.

  In particular, if the support member (46) is provided on the partition plate (44) that partitions the inside of the casing (35) and the upper end portion of the covering member (25) is supported by the support member (46), the casing (35 ), The vibration of the compressor (30) propagated to the partition plate (44) through the bottom plate (43) is attenuated while being propagated by the partition plate (44). ) Is suppressed from propagating to the covering member (25) through the support member (46), and the generation of noise can be reduced.

At this time, the lower end of the side wall member (26) of the covering member (25) is separated from the bottom plate (43) of the casing (35), and the covering member (25) is supported in a suspended posture.

  With this configuration, the hook member (25a) provided on the outer surface of the covering member (25) is engaged with the upper edge of the supporting member (46), thereby supporting the covering member (25). Since it is detachably supported by the member (46), the covering member (25) can be easily attached and detached, and the covering member (25) can be easily used even when maintenance of the compressor (30) is required. It can be removed to work.
