  Embodiments for carrying out the invention will be specifically described with reference to the drawings.

(Overall configuration)
The floor-mounted heat exchange type ventilation fan 1 of the present invention has a substantially rectangular parallelepiped shape, and is divided into two air passages by a rectangular parallelepiped exterior and a partition plate 4 provided in the interior. Including an outside air duct 22, an air supply duct 28, a return air duct 32, and an exhaust duct 38 connected to each other, an air supply air passage for supplying outdoor outdoor air to the room, and an exhaust air passage for discharging indoor air to the outside It is configured. The outline is shown in FIG.

The air supply passage is provided on the exterior of the outside air port 21 provided on the outer wall of the house, the cylindrical outside air duct 22 connected to the outside air port 21, and the floor-mounted heat exchange ventilation fan 1, and the outside air duct 22 is connected thereto. The outside air duct connection port 23, the air supply air passage 25 provided inside the floor-mounted heat exchange type ventilation fan 1, the air supply duct connection port 27 provided on the exterior of the floor type heat exchange type ventilation fan 1, A cylindrical air supply duct 28 connected to the air duct connection port 27 and an air supply port 29 provided on the wall surface or ceiling surface of the room and connected to the air supply duct 28.
In the air supply air passage 25 provided in the floor-type heat exchange type exhaust fan 1, an outdoor air filter 24 that collects dust in the outside air is provided in the vicinity of the outside air duct connection port 23. After the desiccant-type dehumidifier unit 12, the sensible heat exchanger unit 11, the humidifier regenerator 15, and the desiccant-type humidifier unit 13 are provided in this order, finally, in the vicinity of the air supply duct connection port 27, An air supply blower 26 serving as a means for moving air is provided.
Since the air supply blower 26 is provided in the vicinity of the air supply duct 27, most of the air supply air passage 25 is on the suction side of the air supply blower 26, and the outside air flowing inside has a negative pressure.

The exhaust air passage is provided on the exterior of the return air port 31 provided on the wall surface or ceiling surface of the room, the cylindrical return air duct 32 connected to the return air port 31, and the floor-mounted heat exchange type exhaust fan 1. The return air duct connection port 33 to which the return air duct 32 is connected, the exhaust air passage 35 provided in the floor-mounted heat exchange type ventilation fan 1, and the exhaust gas provided on the exterior of the floor type heat exchange type ventilation fan 1. It comprises a duct connection port 37, a cylindrical exhaust duct 38 connected to the exhaust duct connection port 37, and an exhaust port 39 provided on the outer wall of the house and connected to the exhaust duct 38.
In the exhaust air duct 35 provided inside the floor-mounted heat exchange type exhaust fan 1, a return air air filter 34 for collecting dust in the indoor air is provided in the vicinity of the return air duct connection port 33, and the outdoor direction The desiccant humidifier unit 13, the sensible heat exchanger unit 11, the dehumidifying regenerator 14, and the desiccant dehumidifier unit 12 are provided in this order, and finally, the exhaust An exhaust blower 36 serving as means for moving the air in the road is provided.
Since the exhaust blower 36 is provided in the vicinity of the exhaust duct connection port 37, most of the exhaust air passage 35 is on the suction side of the exhaust blower 36, and the indoor air flowing inside has a negative pressure. Since most of the supply air passage 25 has a negative pressure, the pressure difference between the outside air flowing through the supply air passage 25 and the exhaust air passage 35 and the room air becomes small, and the supply air passage 25 and the exhaust air passage Even when a leak occurs at 35, the outside air and room air are less likely to mix with each other, so that the ventilation performance and heat exchange performance of the floor-mounted heat exchange type exhaust fan 1 are less likely to be impaired.

(Sensible heat exchanger unit)
The main functional components of the floor-standing heat exchange type ventilation fan 1 of the present invention will be described. In the sensible heat exchanger unit 11, two broadest opposing surfaces in a flat and substantially rectangular parallelepiped form air-transmitting surfaces. The portion through which air passes is a flat cylindrical shape that is rotated by a motor. The material of the portion through which air passes is a heat absorbing member that stores or releases sensible heat in the air when air is passed through. The two surfaces through which air passes are divided into two at the central portion by the partition plate 4, and one of the divided portions becomes the supply air passage 25 and the other becomes the exhaust air passage 35. When the room is heated, the outside air flowing through the air supply passage 25 passes through the sensible heat exchanger unit 11, whereby the sensible heat of the room air flowing through the exhaust passage 35 can be moved to the outside air. Thereby, during heating, the room can be ventilated without impairing the room heating effect. Conversely, during cooling, the outside air flowing through the air supply passage 25 passes through the sensible heat exchanger unit 11, so that sensible heat can be taken from the outside air by the indoor air flowing through the exhaust passage 35. The room can be ventilated without loss.

(Desicant type dehumidifier unit)
The desiccant-type dehumidifier unit 12 is a flat, substantially rectangular parallelepiped, and the two widest opposing surfaces are surfaces through which air passes. The portion through which the air passes is a cylindrical shape with a flat shape, and an adsorbing element is provided inside, and is configured to be rotated by a motor. The adsorption element has a property of adsorbing or desorbing moisture in the air. The two surfaces through which air passes are divided into two at the central portion, and one of the divided portions serves as the supply air passage 25 and the other serves as the exhaust air passage 35. When the outside air passing through the air supply passage 25 passes through the desiccant-type dehumidifier unit 12, moisture in the outside air is adsorbed by the adsorbing element and exhibits a dehumidifying function. By rotating a flat cylindrical portion through which air passes by a motor, the adsorption element that adsorbs moisture desorbs moisture from the indoor air passing through the exhaust air passage 35. At this time, since the release of moisture from the adsorbing element is insufficient only with the indoor air, the dehumidifying regenerator 14 is provided on the upstream side of the desiccant-type dehumidifier unit 12 in the exhaust air passage 35, and the exhaust air passage 35 is connected to the exhaust air passage 35. The desorption of moisture from the adsorbing element is performed more effectively by heating the indoor air that passes therethrough.

(Desicant type humidifier unit)
The desiccant type humidifier unit 13 is a flat, substantially rectangular parallelepiped, and the two widest opposing surfaces are surfaces through which air passes. The portion through which air passes is a flat columnar shape with an adsorbing element inside, and is structured to be rotated by a motor. The adsorption element has a property of adsorbing or desorbing moisture in the air. The two surfaces through which air passes are divided into two at the central portion, and one of the divided portions serves as the supply air passage 25 and the other serves as the exhaust air passage 35. When the outside air passing through the air supply passage 25 passes through the desiccant humidifier unit 13, the moisture contained in the adsorption element is desorbed by the outside air and exhibits a humidifying function. The adsorbing element from which moisture has been desorbed by rotating a flat cylindrical portion through which air passes by a motor adsorbs moisture contained in the indoor air passing through the exhaust air passage 35. At this time, since desorption of moisture from the adsorbing element by the outside air may be insufficient, the humidification regenerator 15 is provided on the upstream side of the desiccant humidifier unit 13 in the supply air passage 25 and passes through the supply air passage 25. By heating the outside air to be heated, desorption of moisture from the adsorption element is more effectively performed.

  Since the dehumidifying function of the desiccant type dehumidifier unit 12 and the humidifying function of the desiccant type humidifier unit 13 are contradictory functions, the dehumidifying function of the desiccant type dehumidifier unit 12 is The humidifying function of the desiccant type humidifier unit 13 is configured to selectively activate only one function. Therefore, in the floor-mounted heat exchange type exhaust fan 1, the sensible heat exchanger unit 11, the desiccant type dehumidifier unit 12 and the desiccant type humidifier unit 13 are exemplified, but the sensible heat exchanger unit 11 is illustrated. The present invention can also be implemented in a combination of the desiccant type dehumidifier unit 12 and the sensible heat exchanger unit 11 and the desiccant type humidifier unit 13.

  The dehumidifying regenerator 14 and the humidifying regenerator 15 heat air passing through a heat exchanger incorporating an electric heating element, a heat pump heat exchanger, a heat exchanger supplied with a heat medium from an external heat source device, or the like. It has a configuration. In the case where both the desiccant type dehumidifier unit 12 and the desiccant type humidifier unit 13 are provided, the dehumidifying regenerator 14 and the humidifying regenerator 15 are replaced with heat pump heat exchangers, and the desiccant dehumidifier unit 12 is switched by a four-way valve. When operated, the dehumidifying regenerator 14 side is heated and the humidifying regenerator 15 side is cooled. When the desiccant humidifier unit 13 is operated, the humidifying regenerator 15 is heated and the dehumidifying regenerator 14 side is cooled. It can also be. In this case, when the desiccant type dehumidifier unit 12 is operated, it is usually the case where the room is cooled, so there is no problem even if the outside air slightly cooled by the humidifying regenerator 15 is supplied to the room side. As a result, the cooling effect is enhanced. In addition, when the desiccant humidifier unit 13 is operated, indoor heating is performed, but the dehumidifying regenerator 14 cools the heat held in the outside air after passing through the sensible heat exchanger unit 11. It is indoor air after being taken away, and after that, it is only discharged outside, so there is no problem.

The air passage communicating with the return air duct connection port 33 forming the exhaust air passage 35 and the air passage communicating with the exhaust duct connection port 37 are separated. The partition plate 4 </ b> C is provided so as to be continuously connected above the partition plate 4, whereby the upper supply air passage 25 and the exhaust air passage 35 are separated. Note that the dehumidifying regenerator 14 and the humidifying regenerator 15 are not shown in FIG. 3 for simplicity of explanation, but are provided in the same positional relationship as FIG. In addition, the arrow in a figure shows the flow of air.

This space is constructed as a space with some clearance added to the outer shape of the frame outside the integrated air filter, so it cannot be inserted in a state rotated by 90 degrees or 270 degrees. Yes. However, since it can be rotated 180 degrees and inserted, if the outside air filter 24 and the return air filter 34 have different functions, the width A is made slightly smaller toward the back.

An air filter in which the air filter 24 and the return air filter 34 are integrated into a single frame is detachably provided in one direction. In addition, it is often difficult to attach and detach from the bottom plate direction surrounding the front side plate 7a except for a special case due to restrictions on floor placement, but it is possible to insert an air filter from the top plate 6a direction. Therefore, it is good also as the top plate 6a direction.

As a means for preventing erroneous insertion of the third aspect of the invention, the air filter mounting portion of the floor-mounted heat exchange type ventilation fan 2 is configured such that the width dimension A and the depth dimension B of the frame body outside the air filter integrated by one frame are different. This space is constructed as a space with some clearance added to the outer shape of the frame outside the integrated air filter, so it cannot be inserted in a state rotated by 90 degrees or 270 degrees. Yes. However, since it can be rotated 180 degrees and inserted, if the outside air filter 24 and the return air filter 34 have different functions, the width A is made slightly smaller toward the back. The so-called air filter frame outer shape is trapezoidal, so that 180-degree erroneous insertion can be prevented.
In addition, the frame has an asymmetric shape, and the mounting space is matched to that, or even if the frame is a rectangular parallelepiped, a projection is provided on a part thereof, and the air filter mounting portion of the floor-mounted heat exchange ventilation fan 2 An erroneous insertion preventing means can also be achieved by a method of providing a recess that fits into the protrusion.

  FIG. 9 is a perspective view for explaining a split-type air filter in the second embodiment. As with the integrated air filter of FIG. 8, both an outside air filter 24 and a return air filter 34 separated from the left side plate 8 which is an arbitrary side plate are detachably provided from one direction.

As a means for preventing erroneous insertion according to the third aspect of the present invention, a protrusion 41 is provided on a part of the frame of the outdoor air filter 24, and the protrusion 41 is also fitted to the mounting portion of the outdoor air filter 24 of the floor-mounted heat exchange ventilation fan 1. A notch 42 is provided. Similarly, a protrusion 43 is provided on a part of the frame of the return air air filter 34, and a notch 44 that fits the protrusion 43 is also attached to the attachment portion of the return air air filter 34 of the floor-mounted heat exchange ventilation fan 1. Is provided. Thereby, reverse insertion of the outside air filter 24 or the return air filter can be prevented. When the outside air filter 24 and the return air filter 34 have the same function, the outside air filter 24 and the return air filter 34 can have the same outer shape. If the functions of the outside air filter 24 and the return air filter 34 are different, the outside air filter 24 and the return air filter 34 may have different external shape dimensions, or the protrusion 41 and the fitting may be fitted to this. By making the cutout portion 42 and the projection portion 43 to be different from the cutout portion 44 fitted to the cutout portion 42, the external air filter 24 and the return air air filter 34 can be prevented from being erroneously inserted.
Other than the other method of providing the notch, there is also a mistake by providing a protrusion on a part of the frame and providing a recess that fits the protrusion on the air filter mounting portion of the floor-mounted heat exchange ventilation fan 2. It can be an insertion prevention means.

(Dehumidification regenerator)
The dehumidifying regenerator 14 is provided over almost the entire cross section through which the room air of the exhaust air passage 35 passes, and expands the heat conduction area of the metal tube, such as copper having good heat conductivity through which the refrigerant circulates. It is comprised from metal fins, such as aluminum. When the dehumidifying regenerator 14 is a condenser, heat is transferred from the high-temperature and high-pressure gaseous refrigerant to the indoor air flowing on the outer surfaces of the metal pipe and the metal fin, and the refrigerant is liquefied. The indoor air is warmed by the heat of condensation. The warmed room air effectively desorbs moisture adsorbed on the desiccant-type dehumidifier unit 12 and regenerates the dehumidifying function. In the case of an evaporator, heat is removed from the indoor air by the heat of vaporization when the low-temperature and low-pressure refrigerant evaporates. The dehumidifying regenerator 14 is connected to the refrigerant pipe 63 and the refrigerant pipe 65.

(Humidification regenerator)
The humidifying regenerator 15 is provided over almost the entire cross section of the air supply air passage 25 through which the outdoor air passes, and expands the heat conduction area of the metal tube, such as copper having good heat conductivity through which the refrigerant circulates. It is comprised from metal fins, such as aluminum. When the humidifying regenerator 15 is a condenser, heat is transferred from the high-temperature and high-pressure gaseous refrigerant to the air flowing on the outer surfaces of the metal pipe and the metal fin, and the refrigerant is deprived of heat and liquefied. The outdoor air is warmed by the condensation heat at this time. The warmed outdoor air effectively desorbs the moisture adsorbed by the desiccant humidifier unit 13 and exhibits a humidification function.
In the case of an evaporator, the heat of vaporization when the low-temperature and low-pressure refrigerant evaporates takes heat from the room air. The humidifying regenerator 15 is connected to the refrigerant pipe 64 and the refrigerant pipe 65.

(Refrigerant compressor)
The compressor 51 is driven electrically or by an engine, compresses the refrigerant that has become a gas by a rotary (rotary) or reciprocating (reciprocating) method, and easily converts the refrigerant into a high-temperature and high-pressure gas to liquefy the refrigerant. doing. The compressor 51 has a refrigerant pipe 61 connected to the discharge side and a refrigerant pipe 62 connected to the suction side.

(Four-way valve)
The four-way valve 52 is a device that switches the flow path of the refrigeration cycle, and has four connection ports: a connection port 52a, a connection port 52b, a connection port 52c, and a connection port 52d. By electrically driving, the connection port 52a and the connection port 52c communicate with each other inside the four-way valve 52, and the connection port 52b and the connection port 52d communicate with each other inside the four-way valve 52, or the connection port 52a and the connection port 52d. Can communicate with each other inside the four-way valve 52, and the connection port 52b and the connection port 52c can communicate with each other inside the four-way valve 52. A refrigerant pipe 61 is connected to the connection port 52a, a refrigerant pipe 62 is connected to the connection port 52b, a refrigerant pipe 63 is connected to the connection port 52c, and a refrigerant pipe 64 is connected to the connection port 52d.

(Expansion valve)
The expansion valve 53 reduces the pressure of the liquefied refrigerant so that it can be easily vaporized, and the flow rate of the refrigerant passing therethrough can be adjusted by being electrically driven. The expansion valve 53 is provided in the middle of the refrigerant pipe 65.

(Configuration during dehumidifying operation)
The dehumidifying operation will be described with reference to FIG. During the dehumidifying operation, the air supply blower 26 and the exhaust air blower 36 are driven, outdoor air flows from the left to the right in the air supply air passage 25 on the upper side of FIG. 10, and the exhaust air passage on the lower side of FIG. The room air flows through the interior 35 from right to left. The sensible heat exchanger unit 11 and the desiccant type dehumidifier unit 12 are also driven at the same time. In the sensible heat exchanger unit 11, when passing air, the sensible heat in the air is stored through an endothermic member that stores or radiates heat. The movement of heat held by air and room air is performed. In the desiccant type dehumidifier unit 12, the moisture in the outdoor air is adsorbed by the desiccant that adsorbs or desorbs the moisture in the air when the air passes through the desiccant dehumidifier unit 12, and the desiccant type dehumidifier unit in the exhaust air path 35 side. When 12 rotates and moves, the moisture of the desiccant is desorbed by room air heated by the dehumidifying regenerator 14.

  The configuration and operation of the refrigeration cycle during the dehumidifying operation will be described. The four-way valve 52 is in a state where the connection port 52a and the connection port 52c communicate with each other and the connection port 52b and the connection port 52d communicate with each other. Thus, starting from the compressor 51, the refrigerant pipe 61, the four-way valve 52 (connection port 52a and connection port 52c), the refrigerant pipe 63, the dehumidifying regenerator 14, the refrigerant pipe 65, the expansion valve 53 in the middle, and the humidifying regenerator 15 The refrigerant pipe 64, the four-way valve 52 (the connection port 52d and the connection port 52b), and a refrigeration cycle returning from the refrigerant pipe 62 to the compressor 51 are formed.

  By driving the compressor 51 and setting the throttle opening of the expansion valve 53 to a predetermined opening by this refrigeration cycle, the dehumidifying regenerator 14 becomes a condenser and the humidifying regenerator 15 becomes an evaporator. As a result, in the dehumidifying regenerator 14, the high-temperature and high-pressure vaporized refrigerant compressed by the compressor 51 is deprived of heat by the indoor air and liquefied, and the indoor air is warmed by the heat moving to the indoor air. The warmed room air makes it easier for the moisture adsorbed to the desiccant dehumidifier unit 12 to be desorbed, so that the dehumidifying function of the desiccant dehumidifier unit 12 is regenerated. Since the humidifying regenerator 15 is an evaporator, the liquefied refrigerant is vaporized to take heat of the outdoor air, and the outdoor air is cooled and sent to the room.

(Configuration during humidification operation)
The humidifying operation will be described with reference to FIG. During the humidification operation, the air supply blower 26 and the exhaust air blower 36 are driven, outdoor air flows from the left to the right in the supply air passage 25 on the upper side of FIG. 10, and the exhaust air passage on the lower side of FIG. The room air flows through the interior 35 from right to left. The sensible heat exchanger unit 11 and the desiccant type humidifier unit 13 are also driven at the same time. In the sensible heat exchanger unit 11, when passing air, the sensible heat in the air is stored through an endothermic member that stores or radiates heat. The movement of heat held by air and room air is performed. In the desiccant-type humidifier unit 13, the moisture in the room air is adsorbed by the desiccant that adsorbs or desorbs the moisture in the air when the air passes through the desiccant-type humidifier unit 13, and the desiccant-type humidifier unit in the supply air path 25 side. When 13 rotates and moves, the moisture of the desiccant is desorbed by the outdoor air heated by the humidifying regenerator 15.

  The configuration and operation of the refrigeration cycle during the humidification operation will be described. The four-way valve 52 is in a state in which the connection port 52a and the connection port 52d communicate with each other and the connection port 52b and the connection port 52c communicate with each other. Thereby, starting from the compressor 51, the refrigerant pipe 61, the four-way valve 52 (the connection port 52a and the connection port 52d), the refrigerant pipe 64, the humidifying regenerator 15, the refrigerant pipe 65, the intermediate expansion valve 53, and the dehumidifying regenerator 14 The refrigerant pipe 63, the four-way valve 52 (the connection port 52c and the connection port 52b), and a refrigeration cycle returning from the refrigerant pipe 62 to the compressor 51 are formed.

  By driving the compressor 51 and setting the throttle opening of the expansion valve 53 to a predetermined opening by this refrigeration cycle, the humidifying regenerator 15 becomes a condenser and the dehumidifying regenerator 14 becomes an evaporator. Thereby, in the humidification regenerator 15, the high-temperature and high-pressure gaseous refrigerant compressed by the compressor 51 is deprived of heat by the outdoor air and liquefied, and heat is transferred to the outdoor air by the condensation heat at this time. Outdoor air is warmed. The warmed outdoor air makes it easier for the moisture adsorbed to the desiccant humidifier unit 13 to be desorbed, so that the humidifying function of the desiccant dehumidifier unit 13 is regenerated. Since the dehumidifying regenerator 14 is an evaporator, the liquefied refrigerant is vaporized, thereby depriving the indoor air of heat and cooling the indoor air.
