A cylindrical porous body 105 is provided. Then, due to the centrifugal force generated by the rotation of the rotating body 104, water is sucked up from the water storage unit 103, and the water scattered from the rotating body 104 to the outside collides with the peripheral portion through the porous body 105 so that the water is made finer.

As shown in FIG. 9, in the conventional dehumidifying device 200, the air (air X, air Y) sucked into the main body case 202 from the air suction port 201 is passed through the dehumidifying portion 203, and then from the air outlet 204. It is configured to blow out to the outside of the main body case 202. The dehumidifying unit 203 is arranged between the refrigerating cycle in which the compressor 205, the radiator 206, the expander 207, and the heat absorber 208 are connected in this order, and the heat absorber 208 and the radiator 206, and the air X flowing through the first flow path 209 A heat exchanger 211 that exchanges heat between the air and the air Y flowing through the second flow path 210 is provided. Then, the air X flowing through the first flow path 209 is cooled by the heat absorber 208 to cause dew condensation. Condensed water generated by the occurrence of this dew is collected. On the other hand, the air Y flowing through the second flow path 210 exchanges heat with the air X cooled by the heat absorber 208 and is cooled to cause dew condensation. Condensation water generated by the occurrence of this dew condensation is also recovered. As a result, the conventional dehumidifying device 200 dehumidifies the introduced air.

The airflow or air passage before heat exchange shall indicate the airflow or air passage before passing through the heat exchange element 12.

As shown in FIG. 3, the heat exchange type ventilator 50 with a humidity control function according to the first embodiment is a dehumidifying device as a means for imparting a dehumidifying function to the heat exchange type ventilator 10 according to the premise example. It has a configuration in which 30 and a liquid micronization device 60 as a means for imparting a humidifying function are connected. The liquid miniaturization device 60 corresponds to the "humidifying device" of the claim.

Then, in the heat exchange type ventilator 10, as shown in FIG. 3, a switching damper 40 is installed in the exhaust air passage 4 after the heat exchange, and the switching damper 41 and the switching damper 43 are installed in the air supply air passage 5 after the heat exchange. Is installed. The switching damper 40 is a damper for switching between a state in which the exhaust flow 2 flowing through the exhaust air passage 4 flows outdoors and a state in which the exhaust flow 2 flowing through the exhaust air passage 4 flows through the dehumidifying device 30. Further, the switching damper 41 is a damper for switching between a state in which the airflow 3 flowing through the air supply air passage 5 flows indoors and a state in which the airflow 3 flowing through the air supply air passage 5 flows through the dehumidifying device 30. .. Further, the switching damper 43 is provided on the downstream side (indoor side of the air supply air passage 5) from the switching damper 41, and is in a state where the air flow 3 flowing through the air supply air passage 5 flows indoors and the air supply air passage 5 is distributed. This is a damper for switching between a state in which the air supply air flow 3 is flowed through the liquid miniaturization device 60. The airflow 3 that has passed through the dehumidifying device 30 is configured to be led out to the air supply air passage 5 on the upstream side (heat exchange element 12 side) of the switching damper 43.

In the heat exchange type ventilator 50 with a humidity control function, by switching each switching damper (switching damper 40, switching damper 41, switching damper 43), (A) the air supply air 3 after heat exchange becomes the dehumidifying device 30 and the liquid fine. A state in which air is supplied indoors without circulating the chemical device 60, (B) the air supply air 3 after heat exchange flows through the dehumidifying device 30, and then is supplied indoors without circulating the liquid micronization device 60. It is possible to set the state B to be anxious, and (C) the state C in which the air supply air 3 after heat exchange flows through the liquid micronizing device 60 and is supplied indoors without flowing through the dehumidifying device 30. It has become.

In the A state, when dehumidification is not necessary, the air supply air 3 heat-exchanged by the heat exchange type ventilator 10 is supplied indoors as it is.

In the B state, in the summer or the like where dehumidification is required, the dehumidified airflow 3 is supplied indoors after dehumidification is performed on the airflow 3 after heat exchange.

In the C state, in the case of winter or the like where humidification is required, the humidified airflow 3 is supplied indoors after the airflow 3 after heat exchange is humidified.

As described above, in the heat exchange type ventilator 50 with a humidity control function, the air flow 3 is supplied indoors in a state controlled to an appropriate humidity by switching the flow of the air flow 3 from the A state to the C state. It is configured to be. The details of the dehumidifying operation and the humidifying operation will be described later, but when the dehumidifying and humidifying operations are not necessary, the pressure loss due to the dehumidifying device 30 and the liquid micronizing device 60 can be increased by setting the A state. As a heat exchange type ventilator 50 with a suppressed humidity control function, it is possible to realize energy-saving operation throughout the year.

An indoor temperature / humidity sensor 45 for measuring the temperature / humidity of the exhaust flow 2 (indoor air) is installed in the exhaust air passage 4. Then, the heat exchange type ventilation device 50 with a humidity control function adjusts the humidity by the humidity control operation based on the temperature / humidity information from each sensor (outdoor temperature / humidity sensor 44, indoor temperature / humidity sensor 45) of the heat exchange type ventilation device 10. The feedback control of the amount of humidity (the amount of dehumidification in the dehumidifying operation and the amount of humidification in the humidifying operation) is executed. Since a known technique may be used for the method of controlling the feedback of the humidity control amount, the description thereof will be omitted here.

Next, the dehumidifying device 30 in the heat exchange type ventilation device 50 with a humidity control function will be described with reference to FIG.

The dehumidifying device 30 is a unit for dehumidifying the airflow 3 after heat exchange in the heat exchange type ventilator 10. The dehumidifying device 30 includes a refrigerating cycle including a compressor 31, a radiator 32, an expander 33, and a heat absorber 34, and a heat exchanger 35. The refrigeration cycle of the present embodiment is configured by connecting the compressor 31, the radiator 32, the expander 33, and the heat absorber 34 in an annular shape in this order. In the refrigeration cycle, for example, an alternative chlorofluorocarbon (HFC134a) is used as a refrigerant. In addition, copper pipes are often used to connect each device constituting the refrigeration cycle, and they are connected by a welding method.

The compressor 31 is a device that compresses low-temperature and low-pressure refrigerant gas (working medium gas) in the refrigeration cycle to increase the pressure and raise the temperature. In the present embodiment, the compressor 31 raises the temperature of the refrigerant gas to about 45 ° C.

The radiator 32 is a device that releases heat to the outside (outside the refrigeration cycle) by exchanging heat between the refrigerant gas that has become hot and high pressure by the compressor 31 and air (exhaust flow 2). At this time, the refrigerant gas is condensed and liquefied under high pressure. In the radiator 32, the temperature of the introduced refrigerant gas (about 45 ° C.) is higher than the temperature of the air. Therefore, when heat is exchanged, the temperature of the air is raised and the temperature of the refrigerant gas is cooled. The radiator 32 is also referred to as a condenser.

The expander 33 is a device that reduces the pressure of the high-pressure refrigerant liquefied by the radiator 32 to the original low-temperature / low-pressure liquid. The expander 33 is also referred to as an expansion valve.

The endothermic absorber 34 is a device in which the refrigerant flowing through the expander 33 takes heat from the air and evaporates, and the liquid refrigerant is used as a low-temperature / low-pressure refrigerant gas. In the heat absorber 34, the temperature of the introduced refrigerant is lower than the temperature of the air, so that when heat is exchanged, the air is cooled and the temperature of the refrigerant is raised. The endothermic absorber 34 is also referred to as an evaporator.

The heat exchanger 35 is a heat exchanger provided with a sensible heat type heat exchange element. The heat exchanger 35 is arranged in the space between the heat absorber 34 and the radiator 32, similarly to the heat exchanger 211 (see FIG. 9) in the conventional dehumidifier 200. Inside the heat exchanger 35, a first flow path 36 through which air flows in a predetermined direction and a second flow path 37 through which air flows in a direction substantially orthogonal to the first flow path 36 are provided. The first flow path 36 is a flow path for leading the air introduced from the heat absorber 34 to the radiator 32. The second flow path 37 is a flow path for leading the air introduced from the heat exchange type ventilator 10 to the radiator 32. Then, the heat exchanger 35 exchanges only sensible heat between the air flowing through the first flow path 36 and the air flowing through the second flow path 37.

Further, as shown in FIG. 3, the dehumidifying device 30 has a branch damper that divides the heat exchanged airflow 3 introduced inside into two airflows (first airflow 3a and second airflow 3b). 42 is installed. The first airflow 3a is an airflow introduced into the heat absorber 34 and circulates in the first flow path 36, and the second airflow 3b is an airflow introduced into the heat exchanger 35 and circulates in the second flow path 37. is there. The branch damper 42 is configured to have a variable ratio of the air volume of the first air flow 3a and the air volume of the second air flow 3b. That is, the branch damper 42 can easily increase or decrease the ratio of the first airflow 3a to the second airflow 3b by adjusting the angle of the damper (branch ratio of the airflow 3 after heat exchange). It has become.

In the dehumidifying device 30, the first airflow 3a of the divided airflows 3 is distributed in the order of the heat absorber 34, the first flow path 36 of the heat exchanger 35, and the radiator 32, and then in the heat exchange type ventilator 10. It is led out to the air supply air passage 5 after heat exchange. On the other hand, the second airflow 3b is led out to the air supply air passage 5 after the heat exchange after flowing through the second flow path 37 and the radiator 32 of the heat exchanger 35. In the present embodiment, the dehumidifying device 30 merges the first airflow 3a flowing through the heat exchanger 35 with the second airflow 3b flowing through the heat exchanger 35, and then the air supply air passage after heat exchange. It is configured to be derived to 5. As a result, the temperature is adjusted as the airflow 3 blown into the room.

On the other hand, the exhaust flow 2 introduced into the dehumidifying device 30 is led out to the exhaust air passage 4 after heat exchange in the heat exchange type ventilator 10 after flowing through the radiator 32. That is, in the present embodiment, the dehumidifying device 30 is configured such that the radiator 32 is cooled by the exhaust flow 2 introduced from the heat exchange type ventilation device 10.

Next, the dehumidifying operation of the heat exchange type ventilation device 50 with a humidity control function according to the first embodiment will be described.

First, the exhaust fan 13 and the air supply fan 16 are driven by operating the heat exchange type ventilator 50 with a humidity control function, and the exhaust flow flowing through the exhaust air passage 4 is inside the heat exchange type ventilator 10. 2 and the air supply air flow 3 flowing through the air supply air passage 5 are generated.

For example, in summer, the exhaust flow 2 is indoor air air-conditioned to a comfortable temperature and humidity by an air conditioner or the like, and the air supply 3 is hot and humid outdoor air.

Sensible heat and latent heat are exchanged between the exhaust flow 2 and the supply airflow 3 inside the heat exchange type ventilation device 10. At this time, since the moisture moves from the hot and humid supply airflow 3 to the exhaust stream 2, the moisture in the supply airflow 3 is removed. That is, dehumidification (first dehumidification) is performed on the supply airflow 3 by total heat exchange inside the heat exchange type ventilator 10.

Next, the air supply air 3 after heat exchange is introduced into the dehumidifying device 30 to be dehumidified. Specifically, of the airflow 3 introduced into the dehumidifying device 30, the first airflow 3a is cooled by the heat absorber 34. As a result, the temperature of the first airflow 3a becomes equal to or lower than the dew point temperature, and the first airflow 3a condenses, so that the moisture in the first airflow 3a is removed. That is, the dehumidification (second dehumidification) for the first airflow 3a is performed by circulating the heat absorber 34.

In addition, the remaining second airflow 3b of the airflow 3 introduced into the dehumidifying device 30 flows into the second flow path 37 of the heat exchanger 35 and is cooled by the heat absorber 34 in the first flow path 36. It exchanges heat with the first airflow 3a. As a result, the second airflow 3b in the second flow path 37 is cooled and dew condensation occurs, so that the moisture in the second airflow 3b is removed. That is, by exchanging sensible heat with the heat exchanger 35, dehumidification (third dehumidification) is performed for the second airflow 3b.

That is, the heat exchange type ventilator 50 with a humidity control function has a high temperature and humidity outside the room by dehumidification (first dehumidification to third dehumidification) by each device of the heat exchange type ventilator 10, the heat absorber 34, and the heat exchanger 35. Moisture is removed from the air supply air supply 3 of the above, and the necessary dehumidification amount is secured at that time.

Further, the dehumidifying device 30 in the heat exchange type ventilator 50 with a humidity control function introduces the exhaust flow 2 from the exhaust air passage 4 of the heat exchange type ventilator 10, and the introduced exhaust flow 2 flows through the radiator 32. It is composed. In the radiator 32, the introduced exhaust flow 2 exhausts heat equivalent to the energy absorbed by the heat absorber 34 and the energy for circulating the refrigerant in the refrigeration cycle in the compressor 31, and the radiator 32. The exhaust flow 2 that has taken heat from 32 is led out to the exhaust air passage 4 and discharged to the outside as it is. That is, the radiator 32 is cooled by the introduced exhaust flow 2. As a result, the temperature rise of the supply airflow 3 (first airflow 3a, second airflow 3b) accompanying the circulation of the radiator 32 is suppressed.

Next, the liquid miniaturization device 60 in the heat exchange type ventilation device 50 with a humidity control function will be described with reference to FIG.

The water storage unit 70 has a structure in which water is supplied from the water supply port 72 provided on the side wall 68a of the outer cylinder 68, and water is discharged from the drainage port 73 provided on the bottom surface of the water storage unit 70. Here, the drainage port 73 is connected to the water supply / drainage pipe via the water passage 73a, like the water supply port 72. The drain port 73 is preferably provided at the lowest position on the bottom surface of the water storage unit 70.

The liquid miniaturization means 77 is a main part of the liquid miniaturization apparatus 60, and is a place where water is miniaturized. Specifically, the liquid miniaturization means 77 includes a pumping pipe (suction pipe) 74, a rotating plate 75, and a motor 76. Further, the liquid miniaturization means 77 is provided inside the inner cylinder 64, that is, at a position covered by the inner cylinder 64.

The water receiving portion 71 is provided below the water storage portion 70 in the vertical direction over the entire bottom surface of the liquid miniaturizing device 60.

Next, the humidifying operation of the liquid miniaturization device 60 will be described with reference to FIG.

First, the humidifying operation of the liquid miniaturizing device 60 will be briefly described. First, water is supplied from the water supply port 72 to the water storage unit 70 from a water supply / drainage pipe connected to a water supply facility (not shown), and water is stored in the water storage unit 70. Then, the air sucked into the liquid miniaturizing device 60 from the suction port 62 (the air flow 3 after heat exchange or the air flow 3 heated by the dehumidifying device 30) is taken into the suction communication air passage 65 and the inner cylinder air passage. It passes through 66, the liquid miniaturization means 77, and the outer cylinder air passage 69 in this order, and is blown out from the air outlet 63 toward the outside (for example, indoors). At this time, the water droplets generated by the liquid miniaturization means 77 come into contact with the air passing through the inner cylinder air passage 66, and the water droplets are vaporized to humidify the air. Further, the water stored in the water storage unit 70 is discharged to the outside of the device from the drain port 73 after a predetermined time has elapsed.

Next, the humidifying operation of the liquid miniaturizing device 60, that is, how the liquid miniaturizing device 60 humidifies the air will be described in more detail.

The air that has passed through the suction communication air passage 65 from the suction port 62 and is taken into the inner cylinder of the inner cylinder air passage 66 passes through the liquid miniaturization means 77. When the pumping pipe 74 and the rotating plate 75 are rotated by the operation of the motor 76, the water stored in the water storage unit 70 due to the rotation rises along the inner wall surface of the pumping pipe 74. The raised water is stretched along the surface of the rotating plate 75, and is discharged as fine water droplets from the outer peripheral edge of the rotating plate 75 toward the rotating surface. The released water droplets collide with the inner wall surface of the inner cylinder 64 and are crushed to become finer water droplets. The water droplets discharged from the rotating plate 75 and the water droplets crushed by colliding with the inner wall surface of the inner cylinder 64 come into contact with the air passing through the inner cylinder 64, and the water droplets are vaporized to humidify the air. Although some of the generated water droplets are not vaporized, since the liquid micronizing means 77 is arranged so as to be covered with the inner cylinder 64, the unvaporized water droplets adhere to the inner surface of the inner cylinder 64 and store water. It falls on the part 70.

Then, the air containing water droplets (humidified air) is blown out from the ventilation port 67 provided at the lower end of the inner cylinder 64 toward the water storage portion 70 provided below. Then, it flows toward the outer cylinder air passage 69 formed between the inner cylinder 64 and the outer cylinder 68. Here, since the air passing through the outer cylinder air passage 69 is blown upward in the vertical direction, the air flowing downward in the inner cylinder air passage 66 and the air blowing direction are changed to face each other.

At this time, the water droplets blown out from the ventilation port 67 together with the air cannot follow the air flow due to its inertia, and adhere to the water surface 80 of the water storage unit 70 or the inner wall surface of the outer cylinder 68. The heavier the weight of the water droplets, the greater this action, that is, the larger the diameter of the water droplets that are less likely to vaporize, the greater the action, so that the large water droplets can be separated from the flowing air.

Then, the air that has flowed from the inner cylinder air passage 66 into the outer cylinder air passage 69 through the ventilation port 67 flows upward through the outer cylinder air passage 69. Then, it is blown out from the outlet 63. At this time, a part of the water droplets falls to the water storage unit 70 due to gravity, or adheres to the outer wall of the inner cylinder 64 or the inner wall of the outer cylinder 68. Then, the water droplets adhering to the outer wall of the inner cylinder 64 and the inner wall of the outer cylinder 68 fall to the water storage unit 70 along the outer wall surface of the inner cylinder 64 and the inner wall surface of the outer cylinder 68.

By doing so, it is possible to reduce the load of the heat exchange type ventilator 50 with a humidity control function alone, and more reliably perform humidity control control based on the amount of humidity change in the room due to the inflow of outdoor air. be able to.

In the heat exchange type ventilator 50 with a humidity control function according to the first embodiment, the clothes dryer 20 uses the clothes dryer 20 as operation information (second information) of clothes dryness information (dry state A, dry state). The output includes the state B), but is not limited to this. For example, the humidity control unit 51 may output only the start information or the stop information of the clothes dryer 20. In this case, the humidity control unit 51 may control the humidity control with a predetermined humidity control amount (for example, addition dehumidification amount DH2 / subtraction humidification amount H2). By doing so, the configuration of the clothes dryer 20 can be simplified, and the humidity control by the humidity control control unit 51 can be simplified.

The heat exchange type ventilator with a humidity control function according to the present invention makes it possible to suppress a change in indoor humidity that occurs when a blower that blows air to dry clothes operates. It is useful as a heat exchange type ventilation device that enables heat exchange between indoors and outdoors.
