Description

Technical Field

[0001] Embodiments of the present invention relate to a refrigeration cycle apparatus. Background Technology

[0002] A refrigeration cycle device is a device that includes various components (refrigeration cycle components) that constitute a refrigeration cycle. For example, an air conditioner, a chiller, or a heat pump water heater that generates chilled or warm water and uses the generated chilled or warm water for cooling, heating, freezing, or hot water supply are examples of refrigeration cycle devices.

[0003] These refrigeration cycle units are configured to connect multiple modules according to the required capacity. Each module houses refrigeration cycle components such as a compressor, as well as various electrical components for controlling those components within a housing. The compressor, along with the other refrigeration cycle components, is mounted on the module's housing, for example, on a predetermined member (hereinafter referred to as a base) mounted on a frame. Pipes for refrigerant discharge and intake are connected to the compressor.

[0004] When the refrigeration cycle unit starts operating and the compressor begins to work, the compressor vibrates, and this vibration propagates to the connected piping. If the compressor and its piping vibrate, the vibration stress acting on the connection points or the piping itself can sometimes increase, depending on the intensity of the vibration. Therefore, various countermeasures have been taken in the past to suppress the vibration of the compressor and its piping.

[0005] For example, by fixing the compressor to the base via an elastomer (buffer material), vibration can be suppressed from propagating from the compressor to the base. However, compressors have characteristics such as the fixed parts to the base being limited to the legs, and vibration varying with the operating frequency. Therefore, sometimes it is impossible to completely absorb the compressor's vibration using an elastomer.

[0006] Furthermore, vibration stress can be dispersed by adjusting the length or bend shape of the pipes. However, these measures lead to increased space requirements for the pipes, an increase in the number or length of pipes, and the need for additional pipe fixing components. Additionally, at installation sites for refrigeration circulation units, vibration damping frames are sometimes installed to suppress the propagation of vibrations from the compressor to the module housing and then to the mounting surface or building. This incurs additional costs for the vibration damping frames.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0018] (First Embodiment) Figure 1 This is a top view that schematically shows the configuration of the refrigeration cycle apparatus 1 according to this embodiment. Figure 2 From Figure 1 Arrow A12 schematically shows a front view of the configuration of the refrigeration cycle apparatus 1 according to this embodiment. In the following description, as... Figure 1 and Figure 2 The diagram shows the definition of the first direction X, the second direction Y, and the third direction Z. These directions X, Y, and Z are mutually orthogonal. As an example, the first direction X is defined as the width direction, the second direction Y as the depth direction, and the third direction Z as the height direction (vertical direction). However, these directions may not be consistent with the directions in the actual setup of the refrigeration cycle device 1.

[0019] exist Figure 1 and Figure 2 In this example, as a chiller circulation unit 1, a configuration example of an air-cooled heat pump chiller capable of operating in both cooling and heating modes is shown. Figure 1 As shown, the refrigeration cycle device 1 is constructed by connecting multiple refrigeration cycle modules (hereinafter referred to as modules) 11 and 12. In the example shown, the first module 11 and the second module 12 are connected in the second direction Y. That is, the second direction Y corresponds to the connection direction of the two modules 11 and 12. The number of modules constituting the refrigeration cycle device 1 is not particularly limited; it can be one (a single module) or more than three. The first module 11 and the second module 12 have the same basic structure. Therefore, in the following description, the same reference numerals are used for the same constituent elements in each module 11 and 12.

[0020] Modules 11 and 12 include an air heat exchange chamber 101 and a mechanical chamber 102. In the third direction Z (height direction), the air heat exchange chamber 101 is positioned above, and the mechanical chamber 102 is positioned below. The air heat exchange chamber 101 includes two sets of air heat exchange sections 22, 22 as main components. Each air heat exchange section 22, 22 includes a pair of air heat exchangers 29a, 29b and a fan 30.

[0021] Air heat exchangers 29a and 29b, for example, have multiple finned plates and multiple refrigerant pipes running through the finned plates. Figure 1 and Figure 2As shown, the air heat exchangers 29a and 29b are erected in a way that they are spaced apart from each other in the first direction X, which is the width direction of the air heat exchange chamber 101, and are tilted in a way that they are further apart from each other as they move upward in the third direction Z, which is the height direction.

[0022] Furthermore, the two ends of the air heat exchangers 29a and 29b in the second direction Y are bent in opposite directions along the first direction X. The gap between the two ends of the air heat exchangers 29a and 29b is closed by a pair of shielding plates 151 and 151. The cylindrical space enclosed by the air heat exchangers 29a and 29b and the shielding plates 151 and 151 defines an exhaust passage extending in the vertical direction.

[0023] The fan 30 includes, for example, a fan motor that rotates an impeller and a fan shroud surrounding the impeller. The fan motor is supported by a fan base spanning between the upper ends of a pair of air heat exchangers 29a and 29b. The fan shroud has a cylindrical exhaust port opposite to the impeller.

[0024] When the fan 30 is driven, air around the refrigeration circulation unit 1 is drawn into the exhaust passage through the air heat exchangers 29a and 29b. The air drawn into the exhaust passage is sucked up toward the exhaust port and discharged from the exhaust port above the air heat exchangers 29a and 29b.

[0025] The machine room 102 comprises a housing 2, a first refrigeration cycle unit 3, a second refrigeration cycle unit 4, a water circuit 5, and an electrical installation unit 6 as its main components. Figure 1 Only the frame 7 of the housing 2 is shown, indicating the state with the panels (not shown) covering the front, back, right, and left sides of the housing 2 removed. The front and back are the faces viewed from the front and back in the second direction Y, respectively, while the right and left sides are the faces viewed from the sides in the first direction X, respectively. The panels cover the interior of the machine room 102 from the outside.

[0026] The housing 2 is mounted, for example, on a horizontal mounting surface G such as the roof of a building. The housing 2 is formed as an elongated hollow box with a depth dimension (the dimension along the second direction Y) larger than its width dimension (the dimension along the first direction X).

[0027] The shell 2 includes a frame 7. The frame 7 consists of a lower frame 71, an upper frame 72, and a plurality of longitudinal beams 73. The lower frame 71 and the upper frame 72 are elongated rectangular shapes extending along the depth direction of the shell 2. The length of the lower frame 71 along the depth direction of the shell 2 is approximately the same as the length of the upper frame 72 along the depth direction of the shell 2. Furthermore, the length of the upper frame 72 along the width direction of the shell 2 is shorter than the length of the lower frame 71 along the width direction of the shell 2.

[0028] The longitudinal beam 73 is the element connecting the lower frame 71 and the upper frame 72. Figure 1 In the example shown, the longitudinal beams 73 are positioned at both ends and approximately the middle of the shell 2 in the depth direction. The longitudinal beams 73, which are opposite each other in the width direction of the shell 2, are inclined such that they are closer to each other as they move from the lower frame 71 toward the upper frame 72.

[0029] Therefore, as Figure 1 and Figure 2 As shown, when the housing 2 is viewed from the front and back in the second direction Y, the frame 7 is formed as a cone shape whose dimensions gradually narrow from the lower frame 71 to the upper frame 72 along the width direction of the housing 2.

[0030] The lower frame 71 has a base plate 74. The base plate 74, together with multiple panels (not shown) covering the areas enclosed by the lower frame 71, the upper frame 72, and multiple longitudinal beams 73, defines a machine room 102 inside the housing 2. The base plate 74 forms the bottom of the machine room 102. The machine room 102 extends along the entire length of the housing 2 in the depth direction.

[0031] The first refrigeration cycle unit 3 constitutes a refrigeration cycle (refrigerant circuit) corresponding to one of the two sets of air heat exchange sections 22, 22 in the air heat exchange chamber 101. In contrast, the second refrigeration cycle unit 4 constitutes a refrigeration cycle (refrigerant circuit) corresponding to the other of the two sets of air heat exchange sections 22, 22. The refrigeration cycles constituted by these refrigeration cycle units 3 and 4 are independent of each other.

[0032] Figure 3 This is a schematic diagram showing the refrigeration cycle of refrigeration cycle device 1. (Example) Figure 3 As shown, the first refrigeration cycle unit 3 of the first module 11 includes a first refrigerant circuit RA. On the other hand, the second refrigeration cycle unit 4 of the first module 11 includes a second refrigerant circuit RB. As described above, in the refrigeration cycle apparatus 1 according to this embodiment, the first module 11 is connected to the second module 12. Similar to the first module 11, the first refrigeration cycle unit 3 of the second module 12 includes a third refrigerant circuit RC. On the other hand, the second refrigeration cycle unit 4 of the second module 12 includes a fourth refrigerant circuit RD. That is, the refrigeration cycle apparatus 1 is configured to have four independent refrigerant circuits RA, RB, RC, and RD connected to the first module 11 and the second module 12.

[0033] The first to fourth refrigerant circuits RA, RB, RC, and RD are independent refrigerant circuits, but their basic circuit configurations are common. Therefore, the first refrigerant circuit RA of the first refrigeration cycle unit 3 in the mechanical room 102 of the first module 11 will be described below. For the second to fourth refrigerant circuits RB, RC, and RD, the same reference numerals will be used in the accompanying drawings and their descriptions will be omitted.

[0034] like Figure 3 As shown, the first refrigerant circuit RA includes, for example, a variable-capacity hermetic compressor (hereinafter referred to as compressor) 20, a four-way valve 21, an air heat exchanger 22, a pair of expansion valves 23a and 23b, a storage tank 24, a water heat exchanger 25, a liquid receiver 26, and a suction chamber 20a as main components. These components are an example of refrigeration cycle components constituting a refrigeration cycle and are connected via a circulation loop 27 for refrigerant circulation.

[0035] Specifically, the discharge port of compressor 20 is connected to port 21a of four-way valve 21. Port 21b of four-way valve 21 is connected in parallel to the inlet of a pair of air heat exchangers 29a and 29b of air heat exchange section 22. The outlets of air heat exchangers 29a and 29b are connected to port 21c of four-way valve 21 via expansion valves 23a and 23b, storage tank 24, and water heat exchanger 25. Port 21d of four-way valve 21 is connected to the suction side of compressor 20 via liquid receiver 26 and suction chamber 20a.

[0036] like Figure 3 As shown, the water heat exchanger 25 includes a first refrigerant flow path 25a, a second refrigerant flow path 25b, and a water flow path 25c. The first refrigerant flow path 25a of the water heat exchanger 25 is connected to the storage tank 24 of the refrigerant circuit (first refrigerant circuit RA) of the first refrigeration cycle unit 3 of the first module 11 and the third port 21c of the four-way valve 21. Conversely, the second refrigerant flow path 25b of the water heat exchanger 25 is connected to the storage tank 24 of the refrigerant circuit (second refrigerant circuit RB) of the second refrigeration cycle unit 4 of the first module 11 and the third port 21c of the four-way valve 21. In this way, in the first module 11, the first refrigerant circuit RA of the first refrigeration cycle unit 3 and the second refrigerant circuit RB of the second refrigeration cycle unit 4 share a single water heat exchanger 25.

[0037] Similarly, in module 12, the refrigerant circuit of the first refrigeration cycle unit 3 (the third refrigerant circuit RC) and the refrigerant circuit of the second refrigeration cycle unit 4 (the fourth refrigerant circuit RD) also share a water-heat exchanger 25. That is, in Figure 1 and Figure 3 In the example shown, the refrigeration cycle unit 1 is equipped with two water heat exchangers 25.

[0038] like Figure 1 and Figure 3As shown, in modules 11 and 12, all components except the four sets of air heat exchange units 22 are housed in the machine room 102. In module 11, the first refrigeration cycle unit 3 and the second refrigeration cycle unit 4, in other words, the first refrigerant circuit RA and the second refrigerant circuit RB, are positioned, for example, in the rear half of the machine room 102 in the depth direction when viewed from above in the vertical direction (third direction Z). In contrast, in module 11, the electrical assembly unit 6 is positioned, for example, in the front half of the machine room 102 in the depth direction when viewed from above in the vertical direction (third direction Z).

[0039] Similarly, in module 12, the first refrigeration cycle unit 3 and the second refrigeration cycle unit 4, in other words the third refrigerant circuit RC and the fourth refrigerant circuit RD, are positioned, for example, in the rear half of the machine room 102 in the depth direction when viewed from above in the vertical direction (third direction Z). In contrast, in module 12, the electrical assembly unit 6 is positioned, for example, in the front half of the machine room 102 in the depth direction when viewed from above in the vertical direction (third direction Z).

[0040] In this embodiment, the refrigeration cycle device 1 is configured to connect a first module 11 and a second module 12. Therefore, in the depth direction of the refrigeration cycle device 1, i.e., the second direction Y which serves as the connection direction of modules 11 and 12, the electrical installation unit 6 of the second module 12 is configured to be sandwiched between the refrigeration cycle units 3 and 4 of the first module 11 and the refrigeration cycle units 3 and 4 of the second module 12. Specifically, the electrical installation unit 6 of the first module 11 is configured to be sandwiched between the water heat exchangers 25 constituting the refrigerant circuits RA and RB of the first module 11 and the water heat exchangers 25 constituting the refrigerant circuits RC and RD of the second module 12.

[0041] like Figures 1 to 3 As shown, the water heat exchangers 25 of modules 11 and 12 have a square box shape and are erected, for example, from the base plate 74 corresponding to the bottom of the machine room 102 towards the height direction (third direction Z) of the machine room 102. These water heat exchangers 25 have inlet 28a and outlet 28b. In the example shown, when viewed from the front (front of the second direction Y), Figure 1 When observing the shell 2 from the right side (in the middle), the inlet 28a and outlet 28b are located on the left side of the water heat exchanger 25.

[0042] The inlet 28a is connected to the upstream end of the water flow path 25c at the upper end of the left side of the water heat exchanger 25. The outlet 28b is connected to the downstream end of the water flow path 25c at the lower end of the left side of the water heat exchanger 25. Therefore, the water flowing into the water flow path 25c from the inlet 28a flows from top to bottom in the vertical direction (third direction Z) within the water flow path 25c.

[0043] like Figures 1 to 3 As shown, the water circuit 5, together with the first refrigeration cycle unit 3 and the second refrigeration cycle unit 4, is housed in the machine room 102. The water circuit 5 has a pump device (for example, a variable capacity vortex pump) 45 and water pipes 46 as its main components. In this embodiment, as an example, the water pipes 46 are composed of the first to fourth water pipes 46a, 46b, 46c, and 46d.

[0044] like Figure 3 As shown, the first water pipe 46a of the water circuit 5 is connected to the suction port 51 of the pump unit 45. A filter 56 is connected to the rear end of the first water pipe 46a. The rear end of the first water pipe 46a and the filter 56 protrude from the rear end of the refrigeration circulation unit 1, specifically from the rear end of the machine room 102 of the first module 11 in the depth direction (second direction Y). The filter 56 is connected to the outlet of the utilizing equipment such as an air conditioner via accessories such as various valves or flexible joints and field pipes laid on the mounting surface G. That is, water (heat medium) returning from the utilizing equipment flows through the first water pipe 46a.

[0045] The second water pipe 46b is connected between the outlet 52 of the pump unit 45 and the inlet 28a of the water heat exchanger 25 corresponding to the first module 11. The second water pipe 46b is arranged horizontally in the depth direction of the machine room 102.

[0046] The third water pipe 46c connects the outlet 28b of the water heat exchanger 25 corresponding to the first module 11 with the inlet 28a of the water heat exchanger 25 corresponding to the second module 12 in series. That is, through the third water pipe 46c, the water flow path 25c of one water heat exchanger 25 shared by the first refrigerant circuit RA and the second refrigerant circuit RB of the first module 11 is connected in series with the water flow path 25c of another water heat exchanger 25 shared by the third refrigerant circuit RC and the fourth refrigerant circuit RD of the second module 12.

[0047] The fourth water pipe 46d is connected to the outlet 28b of the water heat exchanger 25 corresponding to the second module 12. A discharge pipe 58 with a check valve 57 is connected to the rear end of the fourth water pipe 46d. The rear end of the discharge pipe 58 protrudes from the rear end of the refrigeration circulation unit 1, specifically from the rear end of the machine room 102 of the first module 11 in the depth direction (second direction Y). Furthermore, the check valve 57 is connected to the inlet of the utilizing equipment, such as an air conditioner, via accessories such as various valves or flexible joints and other field pipes laid on the mounting surface G. That is, water (heat medium) supplied to the utilizing equipment flows through the fourth water pipe 46d.

[0048] Therefore, water, serving as a heat transfer medium, circulates between the refrigeration circulation unit 1 and the air conditioning unit or other utilizing equipment. The specific operation of the refrigeration circulation unit 1 at this time will be explained.

[0049] When the refrigeration cycle unit 1 starts operating in cooling mode, the four-way valves 21 of the refrigerant circuits RA and RB in module 11 and RC and RD in module 22, as follows: Figure 3 The switch shown by the solid line connects port 1 21a with port 21b, and port 3 21c with port 4 21d.

[0050] Furthermore, compressors 20 from refrigerant circuits RA, RB, RC, and RD 1 through 4 discharge high-temperature, high-pressure gaseous refrigerant into circulation circuit 27. The high-temperature, high-pressure gaseous refrigerant discharged from compressor 20 is guided to air heat exchangers 29a and 29b via four-way valve 21.

[0051] The gaseous refrigerant guided to air heat exchangers 29a and 29b condenses into a high-pressure liquid refrigerant due to heat exchange with the air passing through the air heat exchangers 29a and 29b. The high-pressure liquid refrigerant is then depressurized as it passes through expansion valves 23a and 23b, becoming an intermediate-pressure gas-liquid two-phase refrigerant. This gas-liquid two-phase refrigerant is then guided to a water heat exchanger 25 via storage tank 24.

[0052] In this embodiment, the first refrigerant circuit RA and the second refrigerant circuit RB share a water heat exchanger 25, and the third refrigerant circuit RC and the fourth refrigerant circuit RD share another water heat exchanger 25. Therefore, in the first refrigerant circuit RA and the second refrigerant circuit RB, the intermediate-pressure gas-liquid two-phase refrigerant is guided to the first refrigerant flow path 25a and the second refrigerant flow path 25b of the water heat exchanger 25, respectively, to exchange heat with the water flowing through the water flow path 25c.

[0053] As a result, the gas-liquid two-phase refrigerant flowing through the first refrigerant flow path 25a and the second refrigerant flow path 25b evaporates and absorbs heat from the water in the water flow path 25c, becoming a low-temperature, low-pressure gas-liquid two-phase refrigerant through the latent heat of vaporization. The water in the water flow path 25c becomes cold water because its latent heat is removed.

[0054] The water flow path 25c of the water heat exchanger 25 shared by the first refrigerant circuit RA and the second refrigerant circuit RB is connected in series with the water flow path 25c of another water heat exchanger 25 shared by the third refrigerant circuit RC and the fourth refrigerant circuit RD via the third water pipe 46c.

[0055] Therefore, the water cooled in the water heat exchanger 25 shared by the first refrigerant circuit RA and the second refrigerant circuit RB is cooled again by exchanging heat with the gas-liquid two-phase refrigerant flowing through the first refrigerant flow path 25a and the second refrigerant flow path 25b of the water heat exchanger 25 as it passes through the water flow path 25c of another water heat exchanger 25 shared by the third refrigerant circuit RC and the fourth refrigerant circuit RD. The water cooled in these two stages is then supplied to the utilization equipment side from the fourth water pipe 46d via field piping.

[0056] The low-temperature, low-pressure gas-liquid two-phase refrigerant that has passed through each water-heat exchanger 25 is guided to the receiver 26 via the four-way valve 21, where it is separated into liquid refrigerant and gaseous refrigerant. The gaseous refrigerant separated from the liquid refrigerant undergoes further gas-liquid separation in the suction chamber 20a and is drawn into the compressor 20, where it becomes a high-temperature, high-pressure gaseous refrigerant again and is discharged from the compressor 20 into the circulation loop 27.

[0057] On the other hand, when the refrigeration cycle unit 1 starts operating in heating mode, the four-way valves 21 of the first to fourth refrigerant circuits RA, RB, RC, and RD, as follows: Figure 3 The switch shown by the dashed line connects port 1 (21a) to port 3 (21c), and port 2 (21b) to port 4 (21d).

[0058] In heating mode, the high-temperature, high-pressure gaseous refrigerant compressed by compressor 20 is guided to water heat exchanger 25 via four-way valve 21. In heating mode, since the water flow path 25c of the water heat exchanger 25 shared by the first refrigerant circuit RA and the second refrigerant circuit RB, and another water flow path 25c shared by the third refrigerant circuit RC and the fourth refrigerant circuit RD, are connected in series, the water flowing through water flow path 25c is heated in two stages by exchanging heat with the gaseous refrigerant flowing through the first refrigerant flow path 25a and the second refrigerant flow path 25b. The water heated by the heat from the gaseous refrigerant is supplied to the user equipment side from the fourth water pipe 46d via field piping.

[0059] The high-pressure liquid refrigerant passing through the water heat exchanger 25 becomes an intermediate-pressure gas-liquid two-phase refrigerant as it passes through the storage tank 24 and expansion valves 23a and 23b, and is simultaneously guided to the air heat exchangers 29a and 29b. The gas-liquid two-phase refrigerant guided to the air heat exchangers 29a and 29b evaporates due to heat exchange with the air passing through them, becoming a low-temperature, low-pressure gas-liquid two-phase refrigerant.

[0060] The low-temperature, low-pressure gas-liquid two-phase refrigerant, having passed through air heat exchangers 29a and 29b, is guided to the receiver 26 via four-way valve 21, where it is separated into liquid and gaseous refrigerants. The gaseous refrigerant separated from the liquid refrigerant is drawn into compressor 20, simultaneously becoming a high-temperature, high-pressure gaseous refrigerant again, and is discharged from compressor 20 into circulation loop 27.

[0061] Next, the configuration of the freezing cycle units 3 and 4 of the first module 11 and the second module 12 involved in this embodiment will be further explained. Figure 4 and Figure 5 The structure of these refrigeration cycle units 3 and 4 is roughly shown in the figure. Figure 4 This is a schematic diagram that roughly shows the configuration of these refrigeration cycle units 3 and 4. Specifically, it roughly shows the front facing the housing 2 (the front in the second direction Y). Figure 1 (Right side of the image) The configuration of freezing cycle units 3 and 4 as observed from the right. Figure 5 From Figure 4 The direction of arrow A45 roughly illustrates the schematic diagram of the configuration of refrigeration cycle units 3 and 4.

[0062] like Figure 4 and Figure 5 As shown, the refrigeration cycle components constituting refrigeration cycle units 3 and 4 are mounted on a base member 81. The base member 81 is a plate-shaped member made of metal such as iron or aluminum, which is non-deformable and has rigidity sufficient to absorb vibrations from the compressor 20. The refrigeration cycle components include the compressor 20 and the water-heat exchanger 25, and are various components constituting the refrigeration cycle in refrigeration cycle units 3 and 4. In this embodiment, in addition to the compressor 20 and the water-heat exchanger 25, the refrigeration cycle components also include, for example, a storage tank 24, a liquid receiver 26, a suction chamber 20a, a four-way valve 21, and a pair of expansion valves 23a and 23b (see reference). Figure 3 ), and pipes connecting these components, etc.

[0063] The compressor 20 is securely (rigidly) fixed to the base member 81 by a fixing member 82. Here, "securely fixed" means a fixing method that suppresses the vibration of the compressor 20 without deforming the fixing member 82. The fixing member 82 is a metal component, such as iron or aluminum, which is non-deformable and has rigidity sufficient to not absorb the vibration of the compressor 20. In other words, the fixing member 82 transmits the vibration to the base member 81 without deforming due to the vibration of the compressor 20. Alternatively, fixing the compressor 20 to the base member 81 by means of bonding or welding can also suppress the vibration of the compressor 20. However, with such fixing methods, for example, it is impossible to remove the compressor 20 from the base member 81 during operations such as inspection, maintenance, or replacement, which risks impairing workability. Therefore, in this embodiment, secure fixing with the ability to remove the compressor is a secondary requirement.

[0064] In the example shown, the fixing member 82 has a tray-shaped receiving portion 82a that contacts and supports the lower part (bottom) 20b of the compressor 20 in the third direction Z. The receiving portion 82a is, for example, a recess along the bottom 20b of the compressor 20 (a recessed portion in the fixing member 82), into which the bottom 20b is embedded and fixed by welding or the like, thus forming an integral part with the compressor 20. The receiving portion 82a has four legs 82b that extend radially relative to the center of the bottom 20b, such as the rotation axis of the rotating mechanism of the compressor 20. These legs 82b are arranged at equal intervals relative to the center of the bottom 20b. The legs 82b are the parts that securely fasten the fixing member 82 as a whole to the base member 81. Holes (through holes) 82d are formed on the legs 82b, allowing fasteners such as screws 82c to pass through.

[0065] A pad 82e is provided between the leg 82b and the base member 81. The pad 82e is a component used to elevate the fixed position of the leg 82b on the base member 81 and to ensure that the leg 82b is in close contact with the fixed position. The material of the pad 82e is not particularly limited, but in this embodiment, it is made of metal as an example. A through hole is formed in the pad 82e, and the through hole is integrally formed with the hole of the leg 82b corresponding to the pad 82e to form a through hole 82d.

[0066] By having the screw 82c pass through the through hole 82d of the leg 82b and the pad 82e and fasten it to the base member 81, the receiving part 82a is securely fixed to the base member 81. Thus, the compressor 20, whose bottom 20b is embedded in the recess of the receiving part 82a, is firmly fixed to the base member 81. Furthermore, the number of legs 82b of the receiving part 82a is not limited to four; it can be three or fewer, or five or more, as long as the compressor 20 can be securely fixed to the base member 81. Moreover, the fastener is not limited to the screw 82c; it can also be a bolt, nut, small screw, etc.

[0067] like Figure 4 and Figure 5 As shown, in this embodiment, the refrigeration cycle components of the two refrigeration cycle units 3 and 4, namely their respective compressors 20, i.e., the two compressors 20, are each securely fixed to a base member 81 by a fixing member 82 having a receiving portion 82a supporting each compressor 20. On the base member 81, near the two compressors 20, are arranged refrigeration cycle components other than the compressors 20 corresponding to these refrigeration cycle units 3 and 4, such as a storage tank 24, a liquid receiver 26, and a suction chamber 20a. As described above, in each module 11 and 12, the first refrigeration cycle unit 3 and the second refrigeration cycle unit 4 share a water-heat exchanger 25. Therefore, a water-heat exchanger 25 shared by these two refrigeration cycle units 3 and 4 is arranged on the base member 81. The method of fixing these refrigeration cycle components other than the compressors 20 relative to the base member 81 is not particularly limited, and any method can be used.

[0068] Here, it is preferable that the total weight of the refrigeration cycle components, excluding the compressor 20, fixed to the base member 81 is equal to or greater than the total weight of the two compressors 20. The total weight of each compressor 20 includes, for example, the weight of the compressor 20 itself, as well as the weight of the fixing member 82 integrally formed with the compressor 20 and fasteners such as screws 82c. That is, it is preferable that the weight of the base member 81, which securely fixes the compressor 20 without the introduction of vibration damping material, is at least 0.8 times and less than 1.5 times the total weight of the compressor 20. Therefore, by setting the total weight of the refrigeration cycle components, excluding the compressor 20, including the water heat exchanger 25, the storage tank 24, and the liquid receiver 26, to about 0.8 to 1.5 times the total weight of the two compressors 20, the vibration of the base member 81 as a whole can be suppressed.

[0069] Furthermore, the total weight of the heaviest component in the refrigeration cycle, namely the water-heat exchanger 25, is set to approximately 0.5 to 1.3 times the total weight of the compressor 20. The water-heat exchanger 25 is preferably positioned diagonally opposite the compressor 20 on the base member 81. This allows for the suppression of vibration while maintaining weight balance on the base member 81.

[0070] In addition, Figure 4 In the example shown, a pad 82e is provided between the leg 82b of the fixing member 82 and the base member 81, thereby firmly fixing the compressor 20 to the base member 81. However, as Figure 6 As shown in the example, the legs 82b of the fixing member 82 can be directly fastened to the base member 81 without the spacer 82e, thereby firmly fixing the compressor 20 to the base member 81. Alternatively, a configuration can be adopted in which the spacer 82e is only inserted between a portion of the legs 82b and the base member 81.

[0071] On the base member 81, two compressors 20, which serve as vibration sources in the refrigeration cycle components, are arranged adjacent to each other. That is, the two compressors 20, which serve as vibration sources relative to the base member 81, are concentrated at a corner of the base member 81. Figure 5 The example shown is the bottom left corner of the image.

[0072] The base member 81, which houses these refrigeration cycle components, is contained within the housing 2. As in this embodiment, by securely fixing the compressor 20 to the base member 81 with the fixing member 82, the intensity of vibration during operation can be suppressed even when the compressor 20 is in operation. However, if the vibration cannot be completely suppressed, the base member 81 may vibrate along with the compressor 20 depending on the residual intensity of the vibration.

[0073] With this in mind, the base member 81 is fixed to the housing 2 by intervening an elastomer 83 between itself and the housing 2. The elastomer 83 is not particularly limited in its construction, as long as it can absorb the vibrations generated by the compressor 20. The elastomer 83 can be made of a viscoelastic material such as rubber or synthetic resin, or a spring, etc.

[0074] like Figure 4 and Figure 5 As shown, in this embodiment, the base member 81 is fixed to the lower frame 71 of the frame 7 constituting the housing 2. In other words, in this embodiment, the frame 7 defines the outline of the space accommodating the base member 81. The method of fixing the base member 81 relative to the lower frame 71 is not particularly limited, and any method can be applied. However, it is required that the method does not hinder the absorption of vibrations generated by the compressor 20 by the elastomer 83. In other words, any fixing method that would hardly absorb vibrations generated by the compressor 20 if the elastomer 83 is omitted is acceptable.

[0075] The lower frame 71 has an outer frame 71a, a first beam 71b, and a second beam 71c. When viewed from above in the third direction Z, the outer frame 71a is approximately rectangular in shape, longer in the second direction Y than in the first direction X. The first beam 71b extends along the longer side (second direction Y) inside the outer frame 71a. The second beam 71c extends along the shorter side (first direction X) inside the outer frame 71a and intersects (orthogonally) the first beam 71b.

[0076] In the example shown, three first beams 71b and three second beams 71c are arranged relative to the outer frame 71a. Furthermore, the first beams 71b are arranged without misalignment with the outer frame 71a in the third direction Z. In contrast, the second beams 71c are arranged to contact the outer frame 71a and the first beams 71b on their upper side in the third direction Z. That is, the second beams 71c are arranged with a misalignment from the outer frame 71a and the first beams 71b in the third direction Z.

[0077] However, the number and arrangement of the first beam 71b and the second beam 71c are not particularly limited. The number of these beams 71b and 71c can be arbitrarily configured, for example, based on the position of the base member 81 in the housing 2, the refrigeration cycle components on the base member 81, and particularly the arrangement of the compressor 20 and the water-heat exchanger 25. Alternatively, for example, the second beam 71c can be arranged without misalignment with the outer frame 71a in the third direction Z, while the first beam 71b is configured to contact the outer frame 71a and the second beam 71c on their upper side in the third direction Z. Alternatively, the first beam 71b and the second beam 71c can also be arranged without misalignment with the outer frame 71a in the third direction Z.

[0078] In this embodiment, a plurality of elastic bodies 83 are provided between the base member 81 and the shell 2. These elastic bodies 83 are made of the same material, and specifically, their vibration absorption performance (damping capacity) is set to be the same. In the example shown, elastic bodies 83 are respectively arranged on the first beam 71b and the second beam 71c of the lower frame 71. Two elastic bodies 83 are arranged on the first beam 71b, and ten elastic bodies 83 are arranged on the second beam 71c.

[0079] The elastic element 83 of the second beam 71c is directly mounted on the second beam 71c. In contrast, the elastic element 83 of the first beam 71b is mounted on the first beam 71b via a pad 84. As described above, the first beam 71b and the second beam 71c are misaligned in the third direction Z. Therefore, the distance between the first beam 71b and the base member 81 in the third direction Z is greater than the distance between the second beam 71c and the base member 81 by this misalignment. Therefore, the misalignment in the third direction Z is raised by the pad 84, thereby mounting the elastic element 83 on the first beam 71b. As a result, the contact surfaces 831 of the plurality of (twelve in the example) elastic elements 83 with the base member 81 are substantially flush with the contact surfaces 811 of the base member 81. Alternatively, instead of the pad 84 shown in the example, a raised portion with the same degree of elevation as the pad 84 can be provided on the second beam 71c, and an elastomer 83 can be installed on the raised portion.

[0080] like Figure 5 As shown, these elastomers 83 are configured to surround fixed positions of the compressors 20 on the base member 81. In the example shown, of the twelve elastomers 83 (83a, 83b), eight elastomers 83a are configured to surround fixed positions of two compressors 20. The remaining four elastomers 83b are further away from the fixed positions of these compressors 20 than the elastomers 83a surrounding the two compressors 20, and are, in short, configured to further surround the elastomers 83a.

[0081] In addition, such as Figure 5 As shown, the elastomers 83 are arranged in greater numbers near the fixed positions of the compressors 20 on the base member 81 than elsewhere. In the example shown, of the twelve elastomers 83 (83a, 83b), eight elastomers 83a are arranged near the fixed positions of two compressors 20. The remaining four elastomers 83b are arranged further away from the fixed positions of the two compressors 20 than the elastomers 83a.

[0082] Furthermore, the arrangement and quantity of elastomers 83a and 83b are not limited to the example shown in the figure. For example, as long as they are arranged around the fixed position of the compressor 20 on the base member 81, and more are arranged near the fixed position of the compressor 20 than outside that position, any number of elastomers 83a and 83b can be arranged at any position.

[0083] According to this embodiment, in the refrigeration cycle device 1, the compressor 20 is securely (rigidly) fixed to the base member 81 by a fixing member 82. Furthermore, the base member 81, on which the compressor 20 is securely fixed, is fixed to the frame 7 by an elastic body 83 interposed between it and the frame 7 of the housing 2.

[0084] Therefore, the vibration generated by the compressor 20 is suppressed by the fixing member 82 between the compressor 20 and the base member 81, and the suppressed vibration propagates from the base member 81 to the frame 7. Therefore, by configuring the elastomer 83 according to the characteristics such as the intensity and frequency of the vibration generated by the compressor 20, the vibration can be flexibly absorbed.

[0085] Since the compressor 20 is securely (rigidly) fixed to the base member 81 by the fixing member 82, vibration of the compressor 20 can be suppressed, as well as vibration propagating to the pipes connected to the compressor 20 and, consequently, to the pipes connected to other refrigeration cycle components besides the compressor 20. Therefore, countermeasures to suppress vibration stress acting on the pipe connection points or the pipes themselves can be limited to the pipes connecting the base member 81 and the outside of the base member 81. Thus, it is not necessary to distribute vibration stress through pipe length or bending shape as in the past, and there is no increase in the space occupied by the pipes, the number or length of pipes, or the addition of pipe fixing members. In other words, it becomes easier to take stress countermeasures against vibration acting on the pipe connection points or the pipes themselves.

[0086] Furthermore, by placing and fixing heavy objects other than the compressor 20, such as the water-heat exchanger 25, storage tank 24, and liquid receiver 26, on the base member 81 on which the compressor 20 is fixed, the overall amplitude and vibration frequency of the base member 81 can be reduced. In particular, by setting the total weight of the other refrigeration cycle components to about 0.8 to 1.5 times the total weight of the compressor 20, the overall vibration of the base member 81 can be suppressed. In addition, by placing the water-heat exchanger 25, which has a total weight of about 0.5 to 1.3 times that of the compressor 20, at a position diagonally opposite to the compressor 20 on the base member 81, and arranging lighter refrigeration cycle components (such as the storage tank 24 and liquid receiver 26) in the remaining space, vibration suppression can be achieved while maintaining weight balance on the base member 81.

[0087] In addition to suppressing the vibration of the compressor 20, the suppressed vibration can also be absorbed by the elastomer 83 between the base member 81 and the frame 7 of the housing 2. That is, the vibration propagating to the frame 7 can be suppressed as much as possible. In other words, since the above-mentioned vibration is absorbed within the housing 2, it is not necessary to separately install anti-vibration supports, such as those for suppressing the propagation of vibration to the mounting surface G of the refrigeration cycle device 1.

[0088] Furthermore, the elastomer 83 is configured to surround the fixed position of the compressor 20 on the base member 81, and is arranged in greater numbers near the fixed position of the compressor 20 than outside that area. Therefore, vibrations generated by the compressor 20 can be absorbed by the elastomer 83 in a more concentrated and effective manner.

[0089] Furthermore, in this embodiment, the first module 11 and the second module 12 of the refrigeration cycle device 1 each have two refrigeration cycle units 3 and 4, respectively. Therefore, on the base member 81, one compressor 20 corresponding to each of these refrigeration cycle units 3 and 4, i.e., two compressors 20, are firmly fixed. These two compressors 20 are concentrated (close to) at a predetermined location on the base member 81. That is, the two compressors 20, which are vibration sources, are concentrated on the base member 81. Therefore, by arranging the elastomer 83 around the fixed positions of these compressors 20 on the base member 81, the vibrations generated by these compressors 20 can be easily absorbed.

[0090] In the above-described embodiment, the characteristics (vibration damping ability) of absorbing vibrations generated by the compressor 20 differ between the vicinity of the compressor 20 and other locations due to the number of elastomers 83. The factors that cause such differences in vibration absorption characteristics are not limited to the number of elastomers 83. For example, the vibration absorption performance of the elastomers may also differ. This embodiment, which differentiates the vibration absorption performance of the elastomers in this way, is described below as the second embodiment.

[0091] Furthermore, the basic structure of the refrigeration cycle device involved in the second embodiment is the same as... Figures 1 to 3 The refrigeration cycle apparatus 1 shown in the first embodiment is the same. Furthermore, the refrigeration cycle of the refrigeration cycle apparatus according to the second embodiment is as follows: Figure 3 The circuit diagram of the refrigeration cycle of the refrigeration cycle apparatus 1 according to the first embodiment is shown. Therefore, regarding the configuration of the refrigeration cycle apparatus of the second embodiment, refer to... Figures 1 to 3 The refrigeration cycle apparatus 1 of the first embodiment shown is described using the same reference numerals.

[0092] (Second Implementation) Figure 7 The configuration of the second embodiment is shown in outline. Figure 7 It is roughly shown from the direction of the arrow in relation to... Figure 4 A schematic diagram of the configuration of the refrigeration cycle units 3 and 4 in the second embodiment at the same location as indicated by arrow A45.

[0093] In this embodiment, a plurality of elastomers 85 are provided between the base member 81 and the housing 2. Unlike the first embodiment, the materials of these elastomers 85, specifically their vibration absorption performance (damping capacity), are not the same. That is, near the fixed position of the compressor 20 on the base member 81, the elastomers 85 are arranged with elastomers made of a material with a greater damping capacity than the material outside this vicinity.

[0094] In the example shown, all, in this case, nine, elastic bodies 85 are arranged on the second beam 71c of the lower frame 71. Similar to the first embodiment, these elastic bodies 85 can be made of viscoelastic materials such as rubber or synthetic resin, or springs, etc. On the other hand, in this embodiment, of the nine elastic bodies 85 (85a, 85b), the four elastic bodies 85a have greater vibration absorption performance (damping capacity) than the other five elastic bodies 85b.

[0095] like Figure 7 As shown, these elastomers 85 are configured to surround fixed positions of the compressors 20 on the base member 81. In the example shown, four elastomers 85a are configured to surround the fixed positions of two compressors 20. Five other elastomers 85b are configured further away from the fixed positions of the compressors 20 than the elastomers 85a surrounding the two compressors 20; in short, they are configured to further surround the elastomers 85a.

[0096] In addition, in this embodiment, such as Figure 7 As shown, in addition to the vicinity of the fixed positions of the compressors 20 on the base member 81, more elastic bodies 85 are disposed than in that vicinity. In the example shown, four elastic bodies 85a are disposed near the fixed positions of the two compressors 20. Five other elastic bodies 85b are disposed further away from the fixed positions of the two compressors 20 than the elastic bodies 85a.

[0097] According to this embodiment, an elastomer 85a with a high vibration absorption capacity (damping ability) is configured around a fixed position of the compressor 20 on the base member 81, and an elastomer 85b with a lower vibration absorption capacity (damping ability) than the elastomer 85a is configured around these elastomers 85a. Therefore, even if no more elastomers 85 are configured near the fixed position of the compressor 20 on the base member 81 than in that vicinity, the vibration generated by the compressor 20 can be effectively absorbed by the elastomers 85.

[0098] In the first and second embodiments described above, the two compressors 20, which serve as vibration sources in the refrigeration cycle component, are arranged close to each other on the base member 81. That is, in the illustrated example, the two compressors 20, which serve as vibration sources, are arranged close together on the base member 81. Furthermore, the water heat exchanger 25, which together with the compressors 20 forms a weight in the refrigeration cycle component, is located at a corner of the base member 81. Figure 5 The example shown is the top right corner of the image.

[0099] These refrigeration cycle components can also be configured with consideration for weight balance on the base member 81. An embodiment that differentiates the vibration absorption performance of the elastomer in this way will be described below as a third embodiment.

[0100] Furthermore, the basic structure of the refrigeration cycle device involved in the third embodiment is similar to... Figures 1 to 3 The refrigeration cycle apparatus 1 shown in the first embodiment is the same. Furthermore, the refrigeration cycle of the refrigeration cycle apparatus according to the third embodiment is as follows: Figure 3 The circuit diagram of the refrigeration cycle of the refrigeration cycle apparatus 1 according to the first embodiment is shown. Therefore, regarding the configuration of the refrigeration cycle apparatus of the third embodiment, refer to... Figures 1 to 3 The refrigeration cycle apparatus 1 of the first embodiment shown is described using the same reference numerals.

[0101] (Third implementation) Figure 8 The configuration of the third embodiment is shown in outline. Figure 8 It is roughly shown from the direction of the arrow in relation to... Figure 4 The diagram shows the configuration of the refrigeration cycle units 3 and 4 in the third embodiment at the same location as indicated by arrow A45.

[0102] In this embodiment, the two compressors 20, which serve as vibration sources in the refrigeration cycle components, are positioned on one side of the base member 81 in the short side direction (first direction X). Figure 8 The example shown is the lower side of the figure). Regarding this, compared to the first embodiment (… Figure 5 )same.

[0103] In contrast, of the two compressors 20, one is disposed at a corner of the base member 81 in the second direction Y (in Figure 8 In the example shown, the bottom left corner of the diagram), another scattered configuration is in another corner of the second direction Y (in Figure 8 (The example shown is the lower right corner of the figure). That is, these compressors 20 are distributed at each of the two corners along the long side (second direction Y) of the base member 81.

[0104] Near these two separately configured compressors 20, there are storage tanks 24, liquid receivers 26, and suction chambers 20a, which are refrigeration cycle components other than each compressor 20.

[0105] Furthermore, the water-heat exchanger 25, which serves as a weight in the refrigeration cycle component, is positioned on the other side of the base member 81 in the short side direction (first direction X). Figure 8 The example shown is the upper side of the figure. Regarding this, compared to the first embodiment (… Figure 5 The same applies. In contrast, the water heat exchanger 25 is positioned between the two compressors 20 along the long side direction (second direction Y) of the base member 81. Figure 8In the example shown, they are positioned roughly in the middle.

[0106] In this embodiment, a plurality of elastic bodies 83 are provided between the base member 81 and the housing 2. Similar to the first embodiment, these elastic bodies 83 are made of the same material and, more specifically, have the same vibration absorption performance (damping capacity).

[0107] like Figure 8 As shown, these elastomers 83 are configured around fixed positions of the respective compressors 20 dispersedly arranged on the base member 81. In the example shown, of the fifteen elastomers 83 (83a, 83b), twelve elastomers 83a are configured around the respective fixed positions of the two dispersed compressors 20. The remaining three elastomers 83b are configured further away from the fixed positions of the compressors 20 than the elastomers 83a surrounding them; in short, they are configured to further surround the elastomers 83a.

[0108] In addition, such as Figure 8 As shown, more elastomers 83 are arranged near the fixed positions of the compressors 20 on the base member 81 than outside of that area. In the example shown, of the fifteen elastomers 83 (83a, 83b), twelve elastomers 83a are arranged near the respective fixed positions of the two dispersed compressors 20. The remaining three elastomers 83b are arranged further away from the fixed positions of these compressors 20 than the elastomers 83a.

[0109] In this embodiment, the compressor 20 and water heat exchanger 25, which are heavy components in the refrigeration cycle components, are distributed relative to the base member 81, which makes the weight balance of the base member 81, where the refrigeration cycle components are arranged, more uniform. Therefore, the vibration of the suppressed compressor 20 can be more properly absorbed by the elastomer 83 between the base member 81 and the frame 7 of the housing 2.

[0110] Alternatively, in addition to distributing two compressors 20 on the base member 81 as in this embodiment, elastomers with different vibration absorption properties can be configured as in the second embodiment. That is, in the third embodiment, similarly to the second embodiment, the characteristics (vibration damping ability) of absorbing vibrations generated by the compressors 20 can be different by making the vibration absorption properties of the elastomers different.

[0111] Several embodiments of the present invention have been described above, but these embodiments are merely examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, and are included in the invention as described in the claims and its equivalents.
