Embodiment mode 1
Fig. 1 is a front view of a dehumidifier 1 according to embodiment 1. Fig. 1 shows an external appearance of a dehumidifier 1. The dehumidifier 1 is used for the purpose of reducing the indoor humidity, for example. Fig. 2 is a sectional view of the dehumidifier 1 of embodiment 1. Fig. 2 shows a cross-section at the position a-a in fig. 1. Fig. 2 shows an internal structure of the dehumidifier 1 according to embodiment 1.
The left direction on the paper of fig. 2 is the front direction of the dehumidifier 1. The right direction on the paper of fig. 2 is the back direction of the dehumidifier 1. The front direction is also referred to as the front direction. The back direction is also referred to as the rear direction. In the present disclosure, as a principle, each direction is defined with reference to a state where the dehumidifier 1 is placed on a horizontal plane.
As shown in fig. 1 and 2, the dehumidifier 1 includes a housing 10. The frame 10 is formed to be self-standing. Housing 10 has suction port 11 and discharge port 12. The suction port 11 is an opening for sucking air from the outside to the inside of the housing 10. The air outlet 12 is an opening for sending air from the inside of the housing 10 to the outside.
In the present embodiment, the suction port 11 is formed in the rear surface portion of the housing 10. Further, the air outlet 12 is formed in an upper surface portion of the frame 10. The suction port 11 and the discharge port 12 may be provided at arbitrary positions. For example, the suction port 11 may be formed in a side portion of the housing 10. In the case where the suction port 11 is formed in a portion of the frame 10 other than the rear surface portion, the dehumidifier 1 can be used in a state where the rear surface is in contact with or close to a wall.
The dehumidifier 1 includes a blower fan 21 as an example of a blower member. Blower fan 21 is housed inside housing 10. An air passage leading from suction port 11 to discharge port 12 is formed inside housing 10. The blower fan 21 is disposed in the air passage. The blower fan 21 is a device that takes in air into the inside of the housing 10 and conveys the taken-in air to the outside of the housing 10.
The dehumidifier 1 of the present embodiment includes an evaporator 31, a compressor 32, a first condenser 33a, and a second condenser 33 b. As shown in fig. 2, the evaporator 31, the compressor 32, the first condenser 33a, and the second condenser 33b are housed inside the housing 10.
The dehumidifier 1 includes a dehumidifying member. The dehumidifying part is a part for removing moisture in the air. The dehumidifying part is constituted by a heat medium circuit. The heat medium circuit is a circuit in which the heat supply medium circulates. Fig. 3 is a schematic view of a heat medium circuit according to embodiment 1. As shown in fig. 3, the dehumidifier 1 includes a pressure reducing device 34. The pressure reducing device 34 is housed inside the housing 10.
In the present embodiment, the heat medium circuit constituting the dehumidifying part is a refrigeration cycle circuit. The refrigeration cycle includes an evaporator 31, a compressor 32, a first condenser 33a, a second condenser 33b, and a pressure reducing device 34.
The heat medium circulates through the evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the pressure reducing device 34. The evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the decompressor 34 are connected via a pipe through which a heat medium flows.
The evaporator 31, the first condenser 33a, and the second condenser 33b are heat exchangers for exchanging heat between the heat medium and the air. The compressor 32 is a device for compressing the heat medium. The pressure reducing device 34 is a device for reducing the pressure of the heat medium. For example, an expansion valve or a capillary tube corresponds to the pressure reducing device 34.
The evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the pressure reducing device 34 each have an inlet and an outlet for the heat medium. The outlet of the evaporator 31 is connected to the inlet of the compressor 32. The heat medium having passed through the evaporator 31 flows into the compressor 32. The compressor 32 compresses the heat medium flowing into the compressor 32. The heat medium compressed by the compressor 32 flows out from the outlet of the compressor 32.
The outlet of the compressor 32 is connected to the inlet of the first condenser 33 a. The outlet of the first condenser 33a is connected to the inlet of the second condenser 33 b. The heat medium compressed by the compressor 32 flows through the first condenser 33a and the second condenser 33 b.
The outlet of the second condenser 33b is connected to the inlet of the pressure reducing device 34. The heat medium having passed through the first condenser 33a and the second condenser 33b flows into the pressure reducer 34. The decompression device 34 decompresses the heat medium flowing into the decompression device 34. The heat medium decompressed by the decompression device 34 expands.
The outlet of the pressure reducing device 34 is connected to the inlet of the evaporator 31. The heat medium decompressed by the decompression device 34 flows into the evaporator 31.
In the present embodiment, the heat medium passes through the evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the pressure reducer 34 in this order. The heat medium absorbs heat from the air in the evaporator 31 and is vaporized. The heat medium vaporized in the evaporator 31 is compressed by the compressor 32 to be in a high-temperature and high-pressure state. The heat medium having passed through the compressor 32 is turned into liquid by radiating heat into the air in the first condenser 33a and the second condenser 33 b. The heat medium having passed through the first condenser 33a and the second condenser 33b is expanded by the pressure reducing device 34 to be in a low-temperature and low-pressure state. Then, the heat medium having passed through the pressure reducing device 34 flows through the evaporator 31 again. In the present embodiment, the heat medium circulates in the refrigeration cycle as described above. The order of connection of the first condenser 33a and the second condenser 33b in the refrigeration cycle may be reversed.
As shown in fig. 2 and 3, the dehumidifier 1 includes a heat absorbing unit 35 and a heat radiating unit 36. The heat absorbing portion 35 and the heat radiating portion 36 are housed inside the housing 10. As shown in fig. 2 and 3, the heat absorbing portion 35 and the heat radiating portion 36 are disposed so as to sandwich the evaporator 31.
The heat absorbing portion 35 and the heat radiating portion 36 are heat exchangers for exchanging heat between the heat medium and the air. The heat absorbing part 35 and the heat radiating part 36 are connected by a heat pipe through which a heating medium circulates. The dehumidifier 1 of the present embodiment includes a precooling member. The pre-cooling means is means for cooling the air before being dehumidified by the dehumidifying means in advance. The precooling unit is constituted by a heat medium circuit. In the present embodiment, the heat medium circuit constituting the precooling member is constituted by the heat absorbing portion 35 and the heat radiating portion 36.
The heat absorbing unit 35 and the heat radiating unit 36 have an inlet and an outlet for the heat medium, respectively. The outlet of the heat sink 35 is connected to the inlet of the heat sink 36. The heat medium having passed through the heat absorbing portion 35 flows into the heat radiating portion 36. The outlet of the heat radiating portion 36 is connected to the inlet of the heat absorbing portion 35. The heat medium having passed through the heat radiating portion 36 flows into the heat absorbing portion 35.
In the present embodiment, the outlet of the heat absorbing unit 35 is located above the inlet of the heat absorbing unit 35. In a state where the housing 10 is placed on a horizontal surface, the outlet of the heat absorbing unit 35 is positioned below the inlet of the heat radiating unit 36. The outlet of the heat dissipation portion 36 is located below the inlet of the heat dissipation portion 36. The outlet of the heat radiating unit 36 is positioned above the inlet of the heat absorbing unit 35.
As described above, the heat absorbing portion 35 and the heat radiating portion 36 are disposed so as to sandwich the evaporator 31. The heat absorbing unit 35 is disposed on the windward side of the evaporator 31. The heat radiating portion 36 is disposed downstream of the evaporator 31. At least a part of the air taken into the interior of the housing 10 by the blower fan 21 passes through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 in this order. That is, the air having passed through the heat absorbing part 35 passes through the evaporator 31. The air having passed through the evaporator 31 passes through the heat radiating portion 36.
The air having passed through the evaporator 31 is cooled by the evaporator 31. The air cooled by the evaporator 31 has a lower temperature than the air in the room. The air cooled by the evaporator 31 passes through the heat radiating portion 36, and the heat medium in the heat radiating portion 36 is cooled. The heat medium in the heat radiating portion 36 radiates heat to the air and liquefies.
The density of the liquefied heat medium is higher than that of the heat medium in a gaseous state. Therefore, the liquefied heat medium descends in the heat radiating section 36 and flows out from the outlet of the heat radiating section 36. The heat medium flowing out of the outlet of the heat radiating unit 36 enters the inlet of the heat absorbing unit 35 located below the outlet.
The heat medium cooled in the heat radiating unit 36 is at a lower temperature than the air in the room. The air taken into the room inside the housing 10 by the blower fan 21 passes through the heat absorbing unit 35 disposed on the windward side of the evaporator 31. The low-temperature heat medium sent from the heat radiating portion 36 to the heat absorbing portion 35 absorbs heat in the air in the heat absorbing portion 35 and is vaporized. The density of the vaporized heat medium is lower than that of the liquid heat medium. Therefore, the vaporized heat medium rises in the heat absorbing unit 35 and flows out from the outlet of the heat absorbing unit 35. The heat medium flowing out of the outlet of the heat absorbing unit 35 enters the inlet of the heat radiating unit 36 located above the outlet. The heat medium having entered the heat radiating portion 36 is again transported to the heat absorbing portion 35.
In the present embodiment, as described above, the heat absorbing unit 35 and the heat dissipating unit 36 naturally circulate the heat medium without requiring power from a compressor or the like because of the phase change between the heat medium in the heat absorbing unit 35 and the heat medium in the heat dissipating unit 36. Unlike the evaporator 31, the heat absorbing unit 35 can absorb heat in the air without requiring power from a compressor or the like.
Fig. 4 is a schematic view showing an air passage inside the housing according to embodiment 1. Fig. 4 corresponds to a view schematically showing a part of the cross-sectional view of fig. 2. The air passage formed inside the housing 10 and the structures of the members disposed in the air passage will be described in more detail with reference to fig. 2 and 4.
As shown in fig. 2 and 4, evaporator 31, first condenser 33a, second condenser 33b, heat absorbing unit 35, and heat radiating unit 36 are disposed in an air passage leading from intake port 11 to discharge port 12. In the present embodiment, the evaporator 31, the first condenser 33a, the second condenser 33b, the heat absorbing unit 35, and the heat radiating unit 36 are disposed between the blower fan 21 and the intake port 11. In addition, as an example, the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, the second condenser 33b, and the first condenser 33a are arranged in this order from the rear to the front.
The first condenser 33a is disposed on the upstream side of the blower fan 21. For example, the first condenser 33a is adjacent to the blower fan 21. The second condenser 33b is disposed upstream of the first condenser 33 a. In the present embodiment, the first condenser 33a and the second condenser 33b are arranged in an adjacent state.
A gap of a predetermined size is provided on the upstream side of first condenser 33a adjacent to blower fan 21. In the present disclosure, this gap is referred to as a mixing space 41. That is, mixing space 41 is formed on the upstream side of first condenser 33a in the air passage leading from suction port 11 to discharge port 12.
Mixing space 41 is formed on the downstream side of heat radiating portion 36 in the air passage leading from intake port 11 to discharge port 12. That is, the mixing space 41 is formed between the heat radiating portion 36 and the first condenser 33 a. In the present embodiment, the second condenser 33b is located between the heat radiating portion 36 and the first condenser 33 a. The mixing space 41 is also a space between the first condenser 33a and the second condenser 33 b.
The air passages leading from suction port 11 to discharge port 12 include a first air passage and a second air passage. The first air passage and the second air passage are formed inside the housing 10. The first air passage is formed as an air passage through which a part of the air taken into the interior of the housing 10 by the blower fan 21 passes through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 in this order and is sent to the mixing space 41. The second air passage is formed as an air passage through which the remaining portion of the air taken into the interior of the housing 10 by the blower fan 21 is delivered to the mixing space 41 without passing through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36.
In the present embodiment, a dehumidification air passage 42, which is an example of the first air passage, is formed inside the housing 10. A bypass air passage 43, which is an example of the second air passage, is formed inside the housing 10. As shown in fig. 2 and 4, the dehumidification air passage 42 and the bypass air passage 43 are air passages leading from the suction port 11 to the mixture space 41.
The dehumidification air duct 42 is formed such that a part of the air taken into the interior of the housing 10 by the blower fan 21 passes through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, the second condenser 33b, and the first condenser 33a in this order. The heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33b are disposed in the dehumidification air passage 42. The dehumidification air duct 42 reaches the mixing space 41 from the suction port 11 via the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b.
The bypass air duct 43 is formed such that the remaining portion of the air taken into the interior of the housing 10 by the blower fan 21 passes through the first condenser 33a without passing through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. The bypass air passage 43 is formed to bypass the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. The bypass air passage 43 reaches the mixing space 41 from the suction port 11 without passing through the evaporator 31, the heat radiation unit 36, and the second condenser 33 b.
The dehumidification air passage 42 as an example of the first air passage and the bypass air passage 43 as an example of the second air passage are formed by an arbitrary method. For example, a partition member 50 for partitioning the dehumidification air passage 42 and the bypass air passage 43 is provided inside the housing 10. The partition member 50 is, for example, a flat plate-like member. The partition member 50 is disposed above the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. The partition member 50 is fixed to the frame body 10.
In the present embodiment, the dehumidification air passage 42 is formed below the partition member 50. The bypass air passage 43 is formed above the partition member 50. In the present embodiment, the bypass air passage 43 is formed above the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b.
The dehumidification air passage 42 and the bypass air passage 43 of the present embodiment are formed by the frame 10 and the partition member 50. Further, the frame body 10 and the partition member 50 may be integrally formed. As described above, the dehumidification air passage 42 and the bypass air passage 43 may be formed by any method. The partition member 50 may not be provided inside the housing 10. The dehumidification air passage 42 and the bypass air passage 43 may be formed by members different from the frame 10 and the partition member 50.
Next, the operation of the dehumidifier 1 of the present embodiment will be described. The arrows in fig. 4 indicate the flow of air when the dehumidifier 1 is operating.
The dehumidifier 1 is operated by the rotation of the blower fan 21. As described above, the dehumidifier 1 is used indoors, for example. When the blower fan 21 rotates, an airflow is generated from the suction port 11 toward the discharge port 12. By generating an air flow by the blower fan 21, the indoor air a1 is taken into the housing 10 through the intake port 11.
The air a1 taken into the casing 10 is branched into the dehumidification air passage 42 and the bypass air passage 43. The first air a2 as a part of the air a1 is guided to the dehumidification air duct 42. The remaining part of the air a1, i.e., the second air A3, is guided to the bypass air passage 43. Second air A3 is the portion of air a1 taken into the interior of housing 10 other than first air a2 guided to moisture removal air passage 42.
The first air a2 guided to the dehumidification air duct 42 passes through the heat absorber 35. Heat is exchanged between the first air a2 passing through the heat absorbing part 35 and the heat medium flowing through the heat absorbing part 35. As described above, the heat medium cooled by the heat radiating portion 36 flows through the heat absorbing portion 35. The heat medium having a lower temperature than the air a1 taken into the casing 10 flows through the heat absorbing unit 35. The heat medium flowing through the heat absorbing part 35 absorbs heat from the first air a2 passing through the heat absorbing part 35. As a result, the temperature of the first air a2 passing through the heat absorbing unit 35 is lowered. In this way, the heat absorption section 35 precools the first air a2 before the first air a2 passes through the evaporator 31. The relative humidity of the first air a2 is higher after passing through the heat absorbing part 35 than before passing through the heat absorbing part 35. In other words, the heat absorbing part 35 increases the relative humidity of the first air a2 by pre-cooling the first air a 2.
The first air a2 precooled by the heat absorbing unit 35 passes through the evaporator 31. Heat exchange is performed between the first air a2 passing through the evaporator 31 and the heat medium flowing through the evaporator 31. As described above, the heat medium decompressed by the decompression device 34 flows through the evaporator 31. The heat medium having a temperature lower than that of the first air a2 precooled by the heat absorbing unit 35 flows through the evaporator 31. The heat medium flowing through the evaporator 31 absorbs heat from the first air a2 passing through the evaporator 31.
The first air a2 passing through the evaporator 31 absorbs heat by the heat medium flowing through the evaporator 31. The first air a2 passing through the evaporator 31 is cooled by the heat medium flowing through the evaporator 31. The temperature of the cooled first air a2 reaches the dew point, and condensation occurs in the evaporator 31. That is, the moisture contained in the first air a2 condenses. The condensed moisture is removed from the first air a 2. The moisture removed from the first air a2 is stored in the water storage tank 13, for example.
The dehumidifier 1 removes moisture in the air, i.e., dehumidifies the air. As described above, the first air a2 is pre-cooled before passing through the evaporator 31. The first air a2 is in a state of high relative humidity before passing through the evaporator 31. Thereby, the dehumidification amount in the evaporator 31 can be increased. According to the present embodiment, the dehumidifier 1 having an excellent dehumidification amount can be obtained as compared with a dehumidifier not equipped with a heat pipe. According to the present embodiment, for example, the power consumption per unit dehumidification amount in the evaporator 31 can be reduced.
The first air a2 cooled in the evaporator 31 is directed toward the heat radiating portion 36. The temperature of the first air a2 heading toward the heat radiating portion 36 from the evaporator 31 is lower than the temperature of the first air a2 heading toward the heat absorbing portion 35 from the suction port 11. The first air a2 from which moisture has been removed by the evaporator 31 passes through the heat radiating portion 36. Heat is exchanged between the first air a2 passing through the heat radiating section 36 and the heat medium flowing through the heat radiating section 36. The heat medium flowing through the heat-radiating section 36 is cooled by the first air a2 passing through the heat-radiating section 36. The temperature of the first air a2 passing through the heat dissipation portion 36 is higher than the temperature of the first air a2 before passing through the heat dissipation portion 36.
The first air a2 passing through the heat sink member 36 is heated by the heat medium flowing through the heat sink member 36. The air heated in the heat radiation unit 36 is directed to the second condenser 33 b. The air heated in the heat radiating section 36 passes through the second condenser 33 b. Heat exchange is performed between the first air a2 passing through the second condenser 33b and the heat medium flowing through the second condenser 33 b. The heat medium flowing through the second condenser 33b is cooled by the first air a2 passing through the second condenser 33 b.
The first air a2 passing through the second condenser 33b is heated by the heat medium flowing through the second condenser 33 b. The first air a2 passing through the second condenser 33b reaches the mixing space 41. In this way, the first air a2 guided to the dehumidification air duct 42 is sent to the mixing space 41 through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b.
As shown in fig. 4, the second air a3 guided to the bypass air passage 43 is sent to the mixing space 41 without passing through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. The first air a2 having passed through the dehumidification air duct 42 and the second air A3 having passed through the bypass air duct 43 are sent to the mixture space 41.
In the mixing space 41, the first air a2 passing through the dehumidification air passage 42 and the second air A3 passing through the bypass air passage 43 are mixed. By mixing the first air a2 with the second air A3, mixed air B1 is generated. As shown in fig. 4, the mixed air B1 passes through the first condenser 33 a. Heat exchange is performed between the mixed air B1 passing through the first condenser 33a and the heat medium flowing through the first condenser 33 a. The heat medium flowing through the first condenser 33a is cooled by the mixed air B1 passing through the first condenser 33 a.
The mixed air B1 passing through the first condenser 33a is heated by the heat medium flowing through the first condenser 33 a. The mixed air B1 is heated by the heat medium, thereby generating dry air B2. The dry air B2 is air in a state of being drier than the indoor air a 1. In addition, the drying air B2 has a higher temperature than the indoor air a 1. The dry air B2 passes through the blower fan 21. The dry air B2 having passed through the blower fan 21 is sent out from the outlet port 12 to the outside of the housing 10. In this way, the dehumidifier 1 supplies the dry air B2 to the outside of the dehumidifier 1.
In the dehumidifier 1 of the present embodiment, a part of the air taken into the inside of the casing 10 passes through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, the second condenser 33b, and the first condenser 33a in this order. The dehumidifier 1 is configured such that the remaining portion of the air taken into the interior of the casing 10 passes through the first condenser 33a without passing through the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. By configuring the dehumidifier 1 as described above, the air volume of the air passing through the evaporator 31 can be increased while maintaining the air volume of the air passing through the first condenser 33a at an appropriate amount for efficiently performing heat exchange between the heat medium flowing through the evaporator 31 and the air passing through the evaporator 31.
In the present embodiment, a mixing space 41 is formed inside the housing 10. In the mixing space 41, the first air a2 having passed through the dehumidification air passage 42 and the second air A3 having passed through the bypass air passage 43 are mixed, thereby generating mixed air B1. According to the present embodiment, the air volume of the air passing through the first condenser 33a can be increased. Further, for example, by changing the position at which the partition member 50 is disposed and adjusting the ratio of the air volumes of the first air a2 and the second air A3, the air volume of the air passing through the first condenser 33a can be adjusted. According to the present embodiment, the amount of heat radiation and the heat radiation efficiency of first condenser 33a can be improved by increasing the amount of air of mixed air B1 passing through first condenser 33 a. Thereby, the efficiency of heat exchange in the first condenser 33a becomes better.
The bypass air passage 43 is not provided with a heat exchanger or the like. Therefore, the pressure loss in the bypass air passage 43 is smaller than that in the dehumidification air passage 42. According to the present embodiment, the air volume of the air passing through the first condenser 33a can be efficiently increased. In the bypass passage 43, a heat exchanger for raising the temperature of the air in the heat radiating unit 36, the second condenser 33b, and the like is not disposed. Therefore, the volume of the mixed air B1 can be increased without increasing the temperature of the mixed air B1.
The dehumidifier 1 of the present embodiment includes a first condenser 33a and a second condenser 33 b. The dehumidifier 1 includes a plurality of condensers, and thereby the condensation temperature of the heat medium in the refrigeration cycle decreases. This reduces the condensation pressure in the refrigeration cycle, and reduces the difference between the condensation pressure and the evaporation pressure. As the difference between the condensing pressure and the evaporating pressure becomes smaller, the load on the compressor 32 is reduced, and the power consumption is reduced.
The second condenser 33b may be disposed in the bypass air passage 43, for example. By providing the second condenser 33b in the bypass air passage 43, the thickness of the dehumidification air passage 42 can be reduced. This makes the dehumidifier 1 more compact.
As described above, the dehumidifier 1 of the present embodiment includes the heat absorbing unit 35 and the heat radiating unit 36 arranged to sandwich the evaporator. The heat absorbing part 35 and the heat radiating part 36 are connected by a heat pipe through which a heating medium circulates. The dehumidifier 1 has a better dehumidification amount than a dehumidifier not equipped with a heat pipe. In addition, a mixing space 41 is formed inside the casing 10 of the dehumidifier 1. A part of the air taken into the interior of the housing 10 is sent to the mixing space 41 through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 in this order. The remaining portion of the air taken into the interior of the housing 10 is not sent to the mixing space through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36. According to the above configuration, the dehumidifier 1 can achieve both the dehumidification capacity in the evaporator 31 and the heat radiation efficiency of the first condenser 33 a.
The heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, the first condenser 33a, and the second condenser 33b may have a flat plate shape, for example. The flat plate-shaped heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 may be arranged so that the surfaces having the largest areas are orthogonal to the flow direction of the first air a 2. For example, the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 are arranged in parallel with each other. The first condenser 33a and the second condenser 33b having a flat plate shape may be arranged in parallel to the heat absorbing portion 35, the evaporator 31, and the heat radiating portion 36 having a flat plate shape.
The first condenser 33a is spaced apart from the second condenser 33b in the first direction. The distance between the first condenser 33a and the second condenser 33b may be larger than the distance between the heat absorbing unit 35 and the evaporator 31, the distance between the evaporator 31 and the heat radiating unit 36, and the distance between the heat radiating unit 36 and the second condenser 33 b. The size of the gap between the first condenser 33a and the second condenser 33b along the first direction may be larger than the size of the gap between the heat absorbing portion 35 and the evaporator 31 along the first direction, the size of the gap between the evaporator 31 and the heat radiating portion 36 along the first direction, and the size of the gap between the heat radiating portion 36 and the second condenser 33b along the first direction. The mixing space 41 may be formed larger than a gap formed between the heat absorbing unit 35 and the evaporator 31, a gap formed between the evaporator 31 and the heat radiating unit 36, and a gap formed between the heat radiating unit 36 and the second condenser 33 b.
By making the volume of the mixing space 41 larger, more second air A3 is introduced into the mixing space 41, and the first air a2 is more uniformly mixed with the second air A3. Thereby, the temperature distribution of the mixed air B1 becomes more uniform. By making the temperature distribution of the mixed air B1 uniform, the heat medium flowing through the first condenser 33a is efficiently cooled by the mixed air B1. The efficiency of heat exchange in the first condenser 33a becomes better.
In the present embodiment, the first air a2 and the second air A3 are mixed in the mixing space 41, thereby generating the mixed air B1 and the dry air B2 having a small temperature difference from the indoor air a 1. Then, dry air B2 having a small temperature difference from the indoor air a1 is blown out from the air outlet 12. Therefore, air of excessively low temperature or air of excessively high temperature is not blown out. According to the present embodiment, the discomfort felt by the user of the dehumidifier 1 is reduced.
In the above embodiment, the mixed air B1 passes through the first condenser 33 a. The mixed air B1 is air in which the first air a2 having passed through the dehumidification air passage 42 and the second air A3 having passed through the bypass air passage 43 merge together. The volume of the mixed air B1 passing through the first condenser 33a may be larger than the volume of the first air a2 passing through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 in the dehumidification air duct 42 inside the housing 10. For example, the inside of the housing 10 may be configured such that all of the mixed air B1 obtained by merging the first air a2 and the second air A3 passes through the first condenser 33 a. This makes it possible to increase the air volume of the air passing through the first condenser 33a without increasing the air volume of the air passing through the evaporator 31. By increasing the air volume of the air passing through the first condenser 33a, the heat radiation amount of the first condenser 33a is increased, and the efficiency of the heat exchange becomes better. Further, the air volume of the air passing through the evaporator 31 can be maintained at an appropriate amount for dehumidification, and the performance of the evaporator 31 for dehumidifying the air can be maintained in a good state. In addition, the housing 10 may be formed with an opening for taking in air into the housing 10, in addition to the suction port 11. The opening is configured such that the air volume passing through the first condenser 33a is larger than the air volume passing through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36.
As shown in fig. 2 and 4, the first condenser 33a may have a size different from that of the second condenser 33 b. Thereby, the amount of heat exchange in the first condenser 33a and the amount of heat exchange in the second condenser 33b can be adjusted, respectively. In addition, the temperature of the first air a2 passing through the dehumidification air duct 42 and the temperature of the mixed air B1 generated in the mixing space can be set to more appropriate temperatures. For example, the mixed air B1 of a lower temperature can be obtained in the mixing space 41. The low-temperature mixed air B1 efficiently cools the heat medium in the first condenser 33a, and the efficiency of heat exchange in the first condenser 33a can be improved.
As shown in fig. 2 and 4, the first condenser 33a may be larger than the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the second condenser 33 b. This increases the volume of the bypass air passage 43. For example, the volume of the second air a3 can be ensured without completely blocking the air flowing through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 from the bypass air passage 43 by the partition member 50. In this way, the first condenser 33a is formed larger than the heat absorbing part 35, the evaporator 31, the heat radiating part 36, and the second condenser 33b, and thus the bypass air passage 43 can be formed inside the housing 10 without the partition member 50 or the like.
As shown in fig. 2 and 4, the upper end of first condenser 33a may be located above the upper ends of heat absorbing unit 35, evaporator 31, and heat radiating unit 36 in a state where casing 10 is placed on a horizontal surface. This allows the bypass air passage 43 to be disposed above the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36. The upper end of the first condenser 33a may be located above the upper end of the second condenser 33 b. This allows the bypass air passage 43 to be disposed above the second condenser 33 b.
The bypass air passage 43 disposed above the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 does not include a pipe connecting the evaporator 31, the compressor 32, the first condenser 33a, the second condenser 33b, and the decompressor 34, and a pipe connecting the heat absorbing unit 35 and the heat radiating unit 36. Since there is no obstacle in the bypass duct 43, the air volume of the air flowing through the bypass duct 43 can be more easily adjusted. In addition, the pressure loss in the bypass air passage 43 is reduced.
For example, the dehumidifier 1 may be configured such that the temperature of the first air a2 passing through the dehumidification air passage 42 is the same as the temperature of the second air A3 passing through the bypass air passage 43, or the temperature of the first air a2 passing through the dehumidification air passage 42 is higher than the temperature of the second air A3 passing through the bypass air passage 43. In this case, in the mixing space 41, the temperature of the first air a2 can be lowered by the second air A3. That is, the mixed air B1 at a lower temperature is generated. By passing the lower temperature mixed air B1 through the first condenser 33a, the heat radiation efficiency of the first condenser 33a becomes better.
Fig. 5 is a diagram showing a first modification of the dehumidifier 1 according to embodiment 1. Fig. 6 is a diagram showing a second modification of the dehumidifier 1 according to embodiment 1. As shown in fig. 5 and 6, the dehumidifier 1 may not include the second condenser 33 b. The dehumidifier 1 may be provided with one dehumidifier 1.
In the modification shown in fig. 5 and 6, the first condenser 33a is spaced apart from the heat radiating portion 36 by a predetermined distance in the first direction. In the modification shown in fig. 5 and 6, the mixing space 41 is a space formed as a gap between the first condenser 33a and the heat radiating portion 36. The distance between the first condenser 33a and the heat radiating portion 36 may be larger than the distance between the heat absorbing portion 35 and the evaporator 31 and the distance between the evaporator 31 and the heat radiating portion 36. The dimension along the first direction of the gap between the first condenser 33a and the heat radiating portion 36 may be larger than the dimension along the first direction of the gap between the heat absorbing portion 35 and the evaporator 31 and the dimension along the first direction of the gap between the evaporator 31 and the heat radiating portion 36. The mixing space 41 may be formed larger than a gap formed between the heat absorbing unit 35 and the evaporator 31 and a gap formed between the evaporator 31 and the heat radiating unit 36.
As shown in fig. 5, the first condenser 33a may be formed larger than the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36, for example. As shown in fig. 6, the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the first condenser 33a may have substantially the same size. As shown in fig. 6, the bypass air passage 43 may be formed by arranging the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the first condenser 33a in a state of being shifted from each other by the same amount.
Fig. 7 is a diagram showing a third modification of the dehumidifier 1 according to embodiment 1. Fig. 7 schematically shows the structure inside the housing 10 in the present modification. Fig. 7 is a schematic view corresponding to a cross-sectional view at a position B-B in fig. 1. As shown in fig. 7, the lateral width of the first condenser 33a may be wider than the lateral width of the heat absorbing part 35, the lateral width of the evaporator 31, and the lateral width of the heat radiating part 36 in a state where the housing 10 is placed on a horizontal plane. Although not shown in fig. 7, the lateral width of the first condenser 33a may be larger than the lateral width of the second condenser 33 b.
The lateral width of the first condenser 33a is a dimension of the first condenser 33a in a direction perpendicular to the flow direction and the vertical direction of the mixed air B1 passing through the first condenser 33 a. The lateral width of the heat absorbing portion 35 is a dimension of the heat absorbing portion 35 in a direction perpendicular to the flow direction and the vertical direction of the first air a2 passing through the heat absorbing portion 35. The lateral width of the evaporator 31 is a dimension of the evaporator 31 in a direction perpendicular to a flow direction and a vertical direction of the first air a2 passing through the evaporator 31. The lateral width of the heat dissipation portion 36 is a dimension of the heat dissipation portion 36 in a direction perpendicular to the flow direction and the vertical direction of the first air a2 passing through the heat dissipation portion 36. The lateral width of the second condenser 33b is a dimension of the second condenser 33b in a direction perpendicular to the flow direction and the vertical direction of the first air a2 passing through the second condenser 33 b.
The bypass air passage 43 can be formed more easily by making the lateral width of the first condenser 33a wider than the lateral width of the heat absorbing portion 35, the lateral width of the evaporator 31, and the lateral width of the heat radiating portion 36. As shown in fig. 7, bypass air passages 43 can be formed on the left and right sides of the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36. Similarly, by making the lateral width of the first condenser 33a wider than the lateral width of the second condenser 33b, the bypass air passage 43 can be easily formed on the side of the second condenser 33 b. The bypass air passage 43 formed at the side of the heat absorbing portion 35, the evaporator 31, the heat radiating portion 36, and the second condenser 33b has fewer obstacles blocking the flow of air than the dehumidification air passage 42. As a result, the second air A3 is efficiently drawn into the bypass air duct 43, and the second air A3 is efficiently guided to the mixing space 41. In addition, as the first condenser 33a becomes larger, the contact area of the first condenser 33a with the mixed air B1 increases. This increases the amount of heat dissipated by the first condenser 33a, and the performance of the first condenser 33a is further improved.
Fig. 8 is a diagram showing a fourth modification of the dehumidifier 1 according to embodiment 1. As shown in fig. 8, the first opening 11a and the second opening 11b may be formed in the housing 10 instead of the suction port 11. The first opening 11a is formed in the back surface of the frame 10, for example. The second opening 11b is formed in, for example, the upper surface of the frame 10. The first opening 11a and the second opening 11b are openings for taking in air from the outside to the inside of the housing 10. According to this modification, since there are a plurality of openings for taking in air from the outside to the inside of the housing 10, for example, the air volume of air passing through the first condenser 33a can be easily made larger than the air volume of air passing through the evaporator 31. According to the configuration of the present modification, the amount of heat radiation of the first condenser 33a can be adjusted more easily.
The air taken in from the first opening 11a corresponds to the first air a2 in the drawings showing the present embodiment and its modified example. The first air a2 taken in from the first opening 11a passes through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36 in this order. The air taken in from the second opening 11b corresponds to the second air a3 in the figures. The second opening 11b is formed such that the second air a3 taken in from the second opening 11b is sent to the mixing space 41 without passing through the heat absorbing unit 35, the evaporator 31, and the heat radiating unit 36. For example, when the heat absorbing unit 35, the evaporator 31, the heat radiating unit 36, and the first condenser 33a are arranged in this order in the horizontal direction, the position of the second opening 11b in the horizontal direction is between the heat radiating unit 36 and the first condenser 33 a. In the modification shown in fig. 8, as in the above-described embodiment and modifications, the air volume of the air passing through the evaporator 31 and the air volume of the air passing through the first condenser 33a can be adjusted to appropriate amounts, respectively. In addition, the heat medium is efficiently cooled, and the efficiency of heat exchange in the first condenser 33a becomes good.
In the above-described embodiment and modifications, the contact area between the mixed air B1 and the first condenser 33a when the mixed air B1 passes through the first condenser 33a may be larger than the contact area between the first air a2 and the evaporator 31 when the first air a2 passes through the heat absorbing unit 35, the contact area between the first air a2 and the evaporator 31 when the first air a2 passes through the evaporator 31, and the contact area between the first air a2 and the heat dissipating unit 36 when the first air a2 passes through the heat dissipating unit 36. In addition, the contact area of the mixed air B1 and the first condenser 33a when the mixed air B1 passes through the first condenser 33a may be larger than the contact area of the first air a2 and the second condenser 33B when the first air a2 passes through the second condenser 33B. The interior of the housing 10 may be configured as described above. According to this configuration, the amount of heat radiation of the heat medium in the first condenser 33a is increased, and heat exchange between the heat medium in the first condenser 33a and the mixed air B1 can be performed more efficiently.
