In the dehumidifying device for dehumidifying the motor, the parts group constituting the electrical component, the parts group constituting the heat exchanger, and the parts group constituting the cooling circuit are respectively made into blocks, and they are divided into blocks. Place separatelyIn addition, each block is a block composed of a part group constituting the electrical component, and is higher than a block composed of a part group constituting the heat exchanger and a block composed of a part group constituting the cooling circuit. Arranged in a hierarchical structureThe gist of the dehumidifier characterized by this is as follows.
[0011]
According to a third aspect of the present invention, in the second aspect, the component group constituting the cooling circuit includes a condenser main body through which the refrigerant flows, air cooling means for air cooling the condenser main body, and driving the air cooling means.

[0023]
According to the fifth aspect of the present invention, the block composed of the component group constituting the electrical component and the other block are separated from each other by the partition wall, so that the component group constituting the electrical component is protected from heat, condensation, dust, and the like. The effect is very small. For this reason, generation | occurrence | production of an electrical failure is avoided reliably and heat exchange efficiency improves further.
[0025]
  Claim6According to the invention described in (1), since the block composed of the parts constituting the electrical component is arranged in the uppermost layer, there is no concern that the dew condensation generated in the other blocks will drop and cause harm. Therefore, the occurrence of an electrical failure due to electric leakage or the like is reliably avoided. Further, since there is a block composed of a group of parts constituting the heat exchanger, a separation distance between the block composed of the part group constituting the electrical component and the block to which the part serving as the heat source belongs is increased. Therefore, the influence which the component group which comprises an electrical equipment part receives from a heat | fever, dew condensation, dust, etc. becomes small reliably compared with the case where the said blocks adjoin. For this reason, generation | occurrence | production of an electrical failure is avoided reliably and heat exchange efficiency improves further.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a refrigeration dehumidifier according to an embodiment of the present invention will be described in detail with reference to FIGS.
[0027]
As shown in FIGS. 1 and 2, a refrigeration circuit R as a cooling circuit is accommodated in a cover 4 constituting the refrigeration dehumidifier 1 of the present embodiment.
Here, the configuration of the refrigeration circuit R will be described. The refrigeration circuit R includes a compressor 5 as a compressor. A compressor drive motor 6 is connected to the compressor 5. The compressor drive motor 6 is connected to a power source (not shown). When the compressor drive motor 6 is driven, the compressor 5 is operated and the refrigerant gas is compressed. Here, the refrigerant refers to a cooling medium such as water, chlorofluorocarbon, or alternative chlorofluorocarbon.
[0028]
An accumulator 8 is assembled on the upstream side of the compressor 5. The accumulator 8 serves to temporarily hold only the liquid refrigerant. Accordingly, only the refrigerant gas is supplied to the downstream compressor 5.
[0029]
The cooling circuit R includes a condenser 9 as a condenser. A condenser body 9 a as a condenser body constituting the condenser 9 is connected to the downstream side of the compressor 5. Refrigerant gas flows in the capacitor body 9a. The capacitor 9 includes a fan 10 as an air cooling means and a fan motor 11 as a driving means in addition to the capacitor body 9a. The fan 10 is disposed close to the back side of the capacitor body 9a. The fan motor 11 is connected to a power source (not shown) and rotationally drives the fan 10 at a predetermined rotational speed. When the fan 10 rotates, outside air around the device 1 is taken into the cover 4. At this time, outside air flows laterally from the filter F1 on the left side of FIG. 2 toward the air duct D1 on the right side. Then, the condenser main body 9a in the middle of the flow of the outside air is entirely cooled with air, and as a result, the compressed refrigerant gas flowing through the condenser body 9a is cooled and liquefied.
[0030]
A filter dryer 12 is assembled on the downstream side of the capacitor 9. The filter dryer 12 contains a filter and a desiccant. The filter dryer 12 serves to remove dust, moisture, and the like in the flow path.
[0031]
On the downstream side of the filter dryer 12, a capillary tube 13 that performs a pressure reducing action is assembled. The capillary tube 13 depressurizes the liquid refrigerant passing through the capillary tube 13.
[0032]
A freezing passage 14 is connected to the downstream side of the capillary tube 13. The refrigeration passage 14 is formed to meander. For the purpose of improving the heat dissipation effect, a large number of fins 14 a are attached to the outer surface of the refrigeration passage 14. The downstream side of the freezing passage 14 is connected to the accumulator 8.
[0033]
The accumulator 8, compressor 5, condenser body 9a, filter dryer 12, capillary tube 13, and refrigeration passage 14 form a main flow path R1 of the refrigeration circuit R.
[0034]
A bypass channel R2 is connected to the main channel R1. One end of the bypass flow path R2 is connected between the compressor 5 and the condenser body 9a, and the other end is connected between the capillary tube 3 and the refrigeration circuit 14. A capacity adjusting valve 15 is provided in the bypass flow path R2. When the capacity adjustment valve 15 is controlled to open and close, the bypass flow path R2 is switched to either the communication state or the cutoff state.
[0035]
Next, the configuration of the dehumidified fluid circuit S will be described. An air compressor 16 for supplying compressed air as a dehumidified fluid is connected to the upstream side of the dehumidified fluid circuit S, and an actuator such as an air cylinder is connected to the downstream side. The compressed air is dehumidified by passing through the dehumidified fluid flow path S.
[0036]
An air supply pipe 17 is connected to the air compressor 16. The air supply pipe 17 is connected to a precooling pipe 18 as a precooling means in the precooling / reheating chamber 2. The precooling tube 18 is formed to meander. A cooling passage 19 in the cooling chamber 3 located below the precooling / reheating chamber 2 is connected to the downstream side of the precooling pipe 18. In the cooling passage 19, there is a refrigeration passage 14 forming a part of the cooling circuit R1. The hot and humid compressed air passing through the cooling passage 19 contacts the refrigeration passage 14. As a result, heat exchange is performed between the compressed air and the refrigerant, and the compressed air is cooled.
[0037]
A reheat pipe 22 as reheat means is connected to the downstream side of the cooling passage 19 via a connection passage 21. The reheat pipe 22 is disposed adjacent to the precooling pipe 18 and is formed to meander in the same manner as the precooling pipe 18. An air extraction pipe 23 provided outside the precooling / reheating chamber 2 is connected to the downstream side of the reheating pipe 22.
[0038]
A drain separator 24 is connected to the middle of the connection passage 21 outside the cooling chamber 3. A drain discharge pipe 25 is drawn out from the drain separator 24. The drain separator 24 separates moisture generated in the cooling chamber 3 from the compressed air. The drain discharge pipe 25 is branched into two along the way, one of which is provided with a drain valve 26 and the other is provided with a manual cock 27. Therefore, by opening the drain valve 26 or the manual cock 27, the water separated by the drain separator 24 is discharged to the outside as drain.
[0039]
In the present embodiment, the dehumidified fluid circuit S is formed by the air supply pipe 17, the precooling pipe 18, the cooling passage 19, the connection passage 21, the drain separator 24, the reheat pipe 22, and the air extraction pipe 23. In addition to these parts 17, 18, 19, 21, 22, 23, 24, the heat exchanger 20 is constituted by a group of parts such as the refrigeration passage 14, the drain discharge pipe 25, the drain valve 26 and the manual cock 27. Yes. Although the refrigeration passage 14 is a part of the refrigeration circuit R, it should be understood as a part of the heat exchanger 20 in view of its function.
[0040]
Next, the configuration of the electrical unit 31 will be described. The electrical component 31 of the present embodiment is configured by a circuit board 32 and various electronic components 33 and electrical components 34 mounted on the circuit board 32. Components such as the compressor drive motor 6, the fan motor 11, the drain valve 26, and the like are electrically connected to the electrical component 31. These parts 6, 11, and 26 are electrically controlled by the electrical component 31.
[0041]
Then, arrangement | positioning of each component in this freezing type dehumidification apparatus 1 is described.
As shown in FIGS. 1 and 2, in the refrigeration dehumidifier 1, each component is divided into blocks according to function. Here, there are three blocks B1, B2 and B3. The first block B <b> 1 is a block B <b> 1 composed of a group of parts constituting the electrical component 31. The second block B2 is a block B2 made up of a group of parts constituting the heat exchanger 20. The third block B3 is a block B3 made up of parts constituting the refrigeration circuit R. Each block B1, B2, B3 is separately arranged in the cover 4. In the second block B2, the components are integrally held by a heat insulating material 28 such as foamed resin.
[0042]
The cover 4 is composed of a plurality of panels (not shown), and covers the frame 40. The frame 40 includes a bottom plate 43, four support columns 44, a first partition wall 41, a second partition wall 42, an upper support frame 45, and the like. The bottom plate 43 has a rectangular shape, and the lower ends of the columns 44 are fixed to the four corners of the bottom plate 43. Each column 44 extends in the vertical direction. The upper support frame 45 is substantially U-shaped and is fixed to the upper end of each column 44. The first and second partition walls 41 and 42 are both supported horizontally by the respective columns 44. The first partition wall 41 is located above the second partition wall 42. These partition walls 41 and 42 are flat metal plates in the present embodiment.
[0043]
When the cover 4 is put on the frame 40, the uppermost layer accommodating space, the intermediate layer accommodating space, and the lowermost layer accommodating space are partitioned and formed hierarchically. The uppermost layer accommodation space is located between the upper side surface of the first partition wall 41 and the lower side surface of the upper panel (not shown). The intermediate layer accommodation space is located between the lower side surface of the first partition wall 41 and the upper side surface of the second partition wall 42. The lowermost layer accommodation space is located between the lower side surface of the second partition wall 42 and the upper side surface of the bottom plate 43.
[0044]
In the uppermost layer accommodating space, a first block B1 composed of a component group (that is, a circuit board 32, an electronic component 33, and an electrical component 34) constituting the electrical component 31 is disposed.
[0045]
In the intermediate layer accommodation space, a second block B2 composed of a group of parts constituting the heat exchanger 20 (that is, the precooling pipe 18, the reheating pipe 22, the drain separator 24, etc.) is arranged. In the lowermost space, a third block B3 consisting of parts constituting the cooling circuit R (that is, the compressor 5, the compressor driving motor 6, the condenser main body 9a, the fan 10, the fan motor 11, the capillary tube 13 and the like) is arranged. Has been.
[0046]
In other words, in the present embodiment, each block is arranged so as to have a three-layered structure in which the first block B1 is the top layer, the second block B2 is the intermediate layer, and the third block B3 is the bottom layer. B1, B2, B3 are arranged.
[0047]
Now, the characteristic effects of the present embodiment will be listed below.
(A) In the refrigeration type dehumidifying apparatus 1 of the present embodiment, the first block B1 consisting of parts constituting the electrical component 31 is separated from the second block B2 consisting of parts constituting the heat exchanger 20. Has been placed. For this reason, the circuit board 32, the electronic component 33, and the electrical component 34 which comprise the electrical equipment part 31 will be in the state spaced apart from components which produce dew condensation, for example, the pre-cooling / reheating chamber 2, the cooling chamber 3, etc. Therefore, the adhesion of dew condensation on the circuit board 32, the electronic component 33, and the electrical component 34 is avoided, and electrical problems such as leakage are less likely to occur.
[0048]
(B) The first block B1 is also arranged separately from the third block B3 made up of parts constituting the refrigeration circuit R. For this reason, the circuit board 32, the electronic component 33, and the electronic component 34 are also in a state of being separated from components that serve as heat sources, such as the compressor drive motor 6 and the fan motor 11. Therefore, the circuit board 32, the electronic component 33, and the electrical component 34 are less likely to be affected by heat, and thus electrical problems such as performance degradation and deterioration of the electrical component 31 are less likely to occur. In addition, even when used in an environment where there is a lot of dust, the dust does not adhere to the circuit board 32, the electronic component 33, and the electrical component 34, thereby preventing the occurrence of electrical problems.
[0049]
(C) In addition to this, a third block B3 consisting of parts constituting the refrigeration circuit R and a second block B2 consisting of parts constituting the heat exchanger 20 are also arranged separately. . As a result, the heat exchanger 20 is less susceptible to the heat of the fan motor 11 and the like, and the heat exchange efficiency is reliably improved accordingly. Moreover, even if there are a plurality of heat sources in the component group constituting the refrigeration circuit R, the heat sources can be integrated into one block by blocking, so that heat can be efficiently discharged outside the apparatus 1.
[0050]
That is, the compressor drive motor 6 and the fan motor 11 which are heat sources belong to the same third block B3. Therefore, by rotating and driving the fans 10 belonging to the same third block B3, their heat is efficiently discharged to the outside of the apparatus 1 through the air duct D1.
[0051]
(D) In the refrigeration dehumidifier 1 of this embodiment, the precooling pipe 18 and the reheating pipe 22 belonging to the same second block B2 are arranged adjacent to each other. For this reason, the pre-cooling tube 18 and the reheating tube 22 can use each other's heat, and the heat exchange efficiency is further improved.
[0052]
(E) In this refrigeration dehumidifier 1, each of the blocks B1 to B3 is arranged so as to have a hierarchical structure consisting of three layers, and in particular, the first block B1 is located in the uppermost layer. Therefore, there is no concern that the condensation generated in the other blocks B2 and B3 will drop and cause harm to the electrical parts 34 and the like belonging to the first block B1. Therefore, the occurrence of an electrical failure due to electric leakage or the like is reliably avoided.
[0053]
Further, since the second block B2 is interposed between the first block B1 and the third block B3, the circuit board 32, the electronic component 33, the electric component 34, and the fan motor 11 serving as a heat source. A large separation distance from the above components is ensured. Therefore, the influence of the circuit board 32, the electronic component 33, and the electric component 34 from heat, condensation, dust, etc. is surely reduced as compared with the case where the blocks B1, B2 are close to each other. For this reason, generation | occurrence | production of an electrical failure is avoided reliably and heat exchange efficiency improves further. Furthermore, space saving of the entire apparatus 1 can be achieved with the hierarchical structure.
[0054]
(F) With the configuration of the refrigeration-type dehumidifier 1, parts can be exchanged for each of the blocks B1, B2, and B3 even when a failure occurs, for example. Moreover, the inside of the apparatus 1 is orderly compared with the conventional one. As a result of the above, maintenance properties are reliably improved.
[0055]
In addition, this invention is not limited to the said embodiment, For example, it can change to another form as follows.
(Circle) you may make it like the freezing type dehumidification apparatus 51 of another example shown by Fig.5 (a). This device 51 also has a hierarchical structure, in which the third block B3 is arranged in the intermediate layer and the second block B2 is arranged in the lowest layer. In this example, the blocks B1 to B3 are isolated by the partition walls 41 and 42.
[0056]
The first block B1 is not necessarily arranged on the uppermost layer. For example, instead of arranging the second block B2 in the uppermost layer as in another example of the refrigerating dehumidifier 52 shown in FIG. 5B, the first block B1 can be arranged in the intermediate layer. . In this example, the blocks B1 to B3 are isolated by the partition walls 41 and 42.
[0057]
◎ In the refrigeration dehumidifier 53 of another example shown in FIG. 5 (c), the hierarchical structure is not adopted, and the second block B2 and the third block B3 are arranged in the same layer (sideways). ing. Therefore, the partition wall 42 that separates these B2 and B3 is formed not vertically but vertically.
[0058]
◎ In another example of the refrigeration dehumidifier 54 shown in FIG. 5D, the second partition wall 42 is omitted and only the first partition wall 41 is used although a three-layer hierarchical structure is adopted. Is provided. That is, it is possible to adopt a configuration in which one or both of the partition walls 41 and 42 are omitted. However, when adopting such a configuration, it is necessary to arrange at least the first block B1 in the uppermost layer. FIG. 5 (f) shows a refrigeration dehumidifier 56 in which both the partition walls 41 and 42 are omitted.
[0059]
The present invention is not limited to a hierarchical structure consisting of three layers. For example, the refrigeration dehumidifier 55 of another example shown in FIG. 5E has a hierarchical structure consisting of four layers by newly adding a fourth block B4. Of course, two layers or five or more layers may be used.
[0060]
In the refrigeration dehumidifier 57 of another example shown in FIG. 5 (g), the hierarchical structure is not adopted, and the blocks B1, B2, B3 are arranged in the horizontal direction in that order. In this example, the blocks B1 to B3 are isolated by the partition walls 41 and 42.
[0061]
In place of the fan 10 that is an air cooling means, for example, a water cooling means may be used. In this case, the fan motor 11 may be omitted, and an adjustment means for adjusting the amount of cooling water, the water temperature, and the like may be provided instead.
[0062]
The present invention is not limited to the refrigeration dehumidifier 1 exemplified in the embodiment, and may be embodied in a dehumidifier using another cooling method that is not refrigeration.
The present invention can be similarly embodied for refrigeration equipment other than the refrigeration dehumidifier 1 illustrated in the embodiment.
