The vaporized water is blown into the room together with the hot air by being vaporized by being applied to the water absorbing material 59 through the air.

Further, Japanese Patent Publication No. Sho 56-55555 discloses an air conditioner having a humidifying function, which discloses a humidifying unit provided with a water-repellent film. The humidifying unit is configured as shown in FIG. In FIG. 6, the entire periphery is sealed with a water-containing tank 62 made of cotton, paper, or the like sandwiched between the two water-repellent films 61, 61, and a pipe is inserted through a part of the periphery to insert a water-containing tank 62. And water supply. The water-repellent film 61 has a large number of minute through-holes 63, which have a sealing property with respect to humidifying water and a permeability with respect to air, water vapor and the like. Therefore, if the film is placed in a dry warm air, the moisture oozing out from the porous film 63 is vaporized by the dry warm air to form humidified warm air.

[0008] As for sterilization of humidified water, Japanese Utility Model Publication No. 1-25050 discloses a humidifying device provided with a germicidal lamp. The humidified water is absorbed by a water-absorbing material, and the humidified water is absorbed. The germicidal material is irradiated with light from a germicidal lamp to sterilize bacteria contained in the humidified water.

[0009]

However, in the air conditioner having a humidifying function disclosed in Japanese Utility Model Publication No. Sho 62-41147 constructed as described above, impurities such as calcium and magnesium dissolved in the humidifying water are removed. There is a problem that the mist is scattered in the room as fog, becomes white powder and adheres to furniture or the like, and that water droplets are likely to adhere near the outlet.

Further, in the air conditioner having a humidifying function disclosed in Japanese Utility Model Laid-Open Publication No. 1-160240, humidified air is discharged into the room, but impurities such as calcium and magnesium contained in the humidifying water are humidified. It accumulates in the humidifier and degrades the humidification performance by adsorbing on the humidification element. In addition, the propagation of pathogenic bacteria in the humidification tank causes humidifier heat and humidifier lungs. In the humidifying device disclosed in the official gazette, humidifying water is sterilized with a germicidal lamp. However, since the life of the germicidal lamp is shorter than other parts, there is a problem in terms of maintenance, and ultraviolet rays are radiated to human eyes. Since it is harmful, there is a problem that it is necessary to consider a protective device, and that the resin molded product as a structural material is deteriorated by the generated ozone.

Further, in the air conditioner having a humidifying function disclosed in Japanese Utility Model Publication No. 56-55555, even in a humidifying unit having a porous membrane using a water-repellent membrane, a hygienic humidifying surface preventing bacteria from permeating. It is not perfect. For example, it is known that staphylococci have a size of 5 micrometers, Escherichia coli has a size of 2 micrometers, and various viruses have a size of 60 to 200 angstroms (in other words, 0.0006 to 0.002 micrometers). On the other hand, as the porous film, there is, for example, a nitroflon porous film NTF (trade name) as a tetrafluoroethylene resin porous film manufactured by Nitto Denko Corporation. In the case of this NTF, the pore size is from 0.03 to
Since it is 4.0 micrometers, there is a problem that transmission of various viruses cannot be prevented.

One of the major problems of an air conditioner having a humidifying function is that humidifying water needs to be supplied. One or several days of humidification water is stored in the water tank, but if the capacity of the water tank is small, the frequency of replenishment will increase, and if the capacity is large, bacteria that cause the aforementioned humidifier heat will proliferate. There was a problem that it became easy to do.

An air conditioner having a humidifying function according to the present invention has been made in order to solve the above-described problems, and enables hygienic humidification in an air conditioner and a troublesome operation for supplying humidifying water. The purpose of the present invention is to provide a so-called maintenance-free humidification unit that eliminates the need for a humidifier.

[0014]

SUMMARY OF THE INVENTION An air conditioner having a humidifying function according to the present invention has been made to achieve the above object, and the invention according to claim 1 is a heat pump having an indoor unit and an outdoor unit.

According to a third aspect of the present invention, in the first aspect of the invention, the humidifying unit is formed by meandering a cylindrical non-porous moisture-permeable membrane having an oval cross section.

According to a fourth aspect of the present invention, in the second and third aspects of the present invention, the surface of the non-porous moisture-permeable membrane of the humidifying unit is subjected to flocking.

It is a fungicide treated by coating or kneading a fungicide into a resin molding material.

[0022]

In the structure of the first aspect, in the heat pump type air conditioner, humidification is required for the room to be air-conditioned on the indoor unit side during the heating operation. In the heat exchanger, the moisture of the outside air condenses on the fin surface and is discharged as drain water. The drain water is conveyed to the indoor unit by a replenishing water conveying means such as a pump incorporated in the outdoor unit and used as replenishing water for the humidifying unit, thereby eliminating the trouble of replenishing the humidifying water. Moreover, humidification
The impurities accumulated in the unit are supplied to the humidification unit.
It is removed only by the drainage operation of the makeup water.

In addition, by using a non-porous moisture permeable membrane in this humidifying unit to selectively allow only water molecules to permeate, not only dust contained in the drain water but also various kinds of indoor air pollution may be caused. It prevents bacteria from permeating.

The non-porous moisture permeable membrane has a very high humidification water permeation rate and selectively permeates only water molecules.
In a state where the partial pressure of water vapor is different across the membrane, water molecules move from the high partial pressure side to the low partial pressure side by using the difference in the partial pressure of water vapor as a driving force, and evaporate into air on the opposite side of the membrane.

Usually, this moisture-permeable membrane is used to dehumidify high-humidity gas by allowing high-humidity gas and low-humidity gas to exist through the membrane. Pressurization by an air compressor or the like is necessary to obtain a pressure difference. When one side of the membrane is made of water and the other side is made of dry air as in the present invention, water molecules move efficiently through the moisture permeable membrane without any particular pressurization.

As described above, this moisture permeable membrane allows only water molecules to permeate, and has little permeation of nitrogen and oxygen as well as dust and impurities, so that very hygienic humidification becomes possible.

In the present invention, the drain water of the outdoor unit is stored in a drain tank below the outdoor heat exchanger, and a driving means such as a pump incorporated in the outdoor unit is driven to supply the drain water to the exclusive unit. It is conveyed to the indoor unit by the drain tube and guided to the humidification unit. The amount of drain water conveyed, that is, the presence or absence of humidification, and the amount of humidification can be controlled by turning on / off the pump or controlling the number of rotations of the pump motor.

According to the second aspect of the present invention, since the non-porous moisture permeable membrane is formed of a hollow fiber-shaped aggregate, the membrane surface area is increased, and dry hot air is easily passed through.
The moisture permeation amount, that is, the humidification amount also increases.

According to the third aspect of the present invention, the moisture-permeable membrane has only a meandering shape in a cylindrical shape having an oval cross section, and has a small number of connection portions, thereby facilitating the production of the humidifying unit.

[0030] In the structure of the fourth aspect, the surface of the moisture permeable membrane is subjected to flocking to increase the evaporation area and improve the humidification efficiency.

According to the fifth aspect of the present invention, the replenishing water is intermittently discharged from the end of the humidifying unit after penetrating the humidifying unit, and the impurities accumulated in the moisture permeable membrane of the humidifying unit flow out and removed. Things.

In the above configuration, the amount of drain water conveyed from the outdoor unit is controlled by turning on / off the pump serving as the replenishing water conveying means or controlling the number of revolutions of the pump motor. Then, the humidification amount is controlled.

In the above configuration, the drain water of the outdoor heat exchanger is at a low temperature, and dew condensation easily occurs on the surface of the auxiliary drain tube on the warm indoor unit side. Therefore, if the air conditioner is installed adjacent to the auxiliary pipe, which is a refrigerant pipe, and is insulated together, installation work of the air conditioner is facilitated.

[0034] In the structure of the eighth aspect, the vicinity of the humidifying unit in a wet state by the antifungal treatment is protected from mold and mites.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner having a humidifying function according to the present invention will be described below with reference to FIGS.

One embodiment of the air conditioner having a humidifying function of the present invention is configured as shown in FIG. 1. In FIG. 1, reference numeral 11 denotes an indoor unit, and 21 denotes an outdoor unit. Indoor unit 1
1 and the outdoor unit 21 are connected to a refrigerant pipe 31, a drain tube 32 serving as a transport path for transporting drain water on the outdoor side to the humidifying unit 1 on the indoor side, power wiring (not shown), and control circuit wiring (not shown). And so on. Inside the indoor unit 11, the indoor heat exchanger 4, the drain plate 6 for receiving condensed water of the indoor heat exchanger 4, the indoor blower 2, the air suction port 5, the air outlet 7, and the air serving as an air passage by the indoor blower 2. A humidity sensor 3 is provided between the suction port 5 and the indoor heat exchanger 4,
A humidifying unit 1 is provided between the air conditioner and the indoor blower 2 together with a fixing member. It also includes a control circuit, a motor for the indoor blower 2, and an electrical unit (not shown) such as a wiring connection unit.

An auxiliary pipe 12 is provided in the indoor heat exchanger 4 and is connected to a refrigerant pipe 31 to form a refrigerant passage. The humidification unit 1 is provided with an auxiliary drain tube 8, which is connected to the drain tube 32 and serves as a transport path for drain water from the outdoor unit 21, that is, supply water for the humidification unit 1. The humidification unit 1 is provided with a drainage hose 9 serving as a drainage channel, and the lower end thereof is connected to the drain plate 6. The drain hose 9 is provided with a solenoid valve 10 in the middle thereof to control the opening and closing of the drain passage.

A drain hose 13 is connected to a lower end of the indoor unit 11 to drain water from the drain plate 6 and the like. Since the low-temperature drain water from the indoor heat exchanger 4 flows through the drain hose 13 during cooling, the drain hose 13 is an insulated hose to prevent dew condensation. A low-temperature refrigerant and low-temperature drain water flow through the auxiliary pipe 12 and the auxiliary drain tube 8, and together with the cylindrical heat insulating material 14 to prevent condensation.
Insulated at

The outdoor unit 21 includes an outdoor heat exchanger 22, a drain tank 23 for storing drain water below the outdoor heat exchanger 22, an outdoor blower 24,
And a motor (not shown), a compressor (not shown), an electrical unit (not shown), and the like.

The drain tank 23 is provided with a pump 26 serving as drain water conveying means, and is connected to a drain tube 32. In addition, a water level sensor, a temperature sensor,
An electric heater serving as drain water thawing means or a heating section comprising a high-temperature refrigerant discharge section of a compressor is provided. This is because the drain water freezes during winter heating depending on the outside air temperature.

Next, a description will be given of a use state of an embodiment of the air conditioner having the humidifying function of the present invention configured as described above.

In the air conditioner having the humidifying function during the heating operation, the warm air heat exchanged in the indoor heat exchanger 4 passes through the humidifying unit 1 to vaporize the moisture permeating the moisture permeable membrane, and the indoor blower 2 blows out into the non-conditioned room.
During heating, the drain water of the outdoor unit 21 accumulates in a drain tank 23 below the outdoor heat exchanger 22. When the water level sensor detects that the drain water has reached a certain level or higher, the pump 26 built in the outdoor unit 21 is driven to cause the drain water to flow through the dedicated drain tube 32 and the auxiliary drain tube 8 to the indoor unit. 11 and is guided to the humidification unit 1.

The moisture permeable membrane of the humidifying unit 1 needs to be non-porous and has a selectively high water molecule permeation rate.
Usually, a polyimide-based or fluorine-based film is used. As the non-porous film, for example, there is a fluorine-based water vapor permeable film SUNSEP-W (trade name) developed by Asahi Glass Co., Ltd. This is a type of gas separation membrane that has a very high water permeation rate and exhibits the behavior of a membrane that selectively permeates only water molecules. S
The fact that the permeation mechanism of water vapor in the UNSEP-W membrane is not sufficiently elucidated, and that molecules other than water, such as nitrogen and oxygen, hardly permeate the membrane (except for water-soluble acid gas, which is an exception). Etc. are described in the material. Since it is a non-porous film, it is a film composed of a dense layer without pores, and it is possible to prevent permeation of various viruses and the like as compared with a porous film, that is, a film having fine pores.

The permeation rate of water molecules is proportional to the permeability coefficient specific to the membrane material and the difference between the membrane area and the partial pressure of water vapor on both sides of the membrane. . If water is passed through one side of the membrane and dry air is on the other side, the portion corresponding to the partial pressure difference of water vapor becomes very large. If both sides of the membrane are gas, it is necessary to pressurize one side of the gas with a compressor or depressurize the other side of the gas with a vacuum pump. Even if this is not performed, a practically sufficient transmission speed can be obtained.

One embodiment of the humidifying unit shown in FIG. 1 is constructed as shown in FIG. 2. In FIG. 2, reference numeral 15 denotes a moisture permeable membrane formed in a hollow fiber shape, and both ends thereof are respectively provided with water supply pipes. 18, connected to a drain pipe 19. Humidifying unit start end 1 which is one end of water supply pipe 18
Humidifying water is supplied from 8A, and drained as necessary from the humidifying unit end portion 19B which is one end of the drain pipe 19. Since the non-porous moisture permeable membrane 15 is an aggregate formed in a hollow fiber shape, the membrane surface area is increased, and it is easy to pass dry hot air, and the moisture permeation amount is increased.

Another embodiment of the air conditioner having a humidifying function according to the present invention is configured as shown in FIG.
In this case, the moisture permeable membrane 27 is merely meandering in a cylindrical shape having an oval cross section, and the number of connections is small, so that the production of the humidifying unit is facilitated. It is also obvious that if a corrugated spacer or the like (not shown) is inserted between the meandering moisture permeable membranes, warm air can easily pass through and the humidification amount increases. In this case, the humidifying water is supplied from the humidifying unit starting end 27A,
The water is drained from the humidifying unit end portion 27B.

Further, the hollow fiber-shaped moisture permeable membrane 15 shown in FIG.
When the surface of the moisture permeable membrane 27 having the oval cross section is surface-treated by electric flocking or the like, the evaporation area increases, and more efficient humidification can be performed.

Drain water has less water-soluble components such as calcium and magnesium than tap water because water in the air is condensed on the fin surface, but contains dust in the outside air and corrosion products of structural members. ing. Since only water molecules move in the non-porous moisture permeable membrane, impurities are accumulated in the humidification unit over time in this humidification method. In order to prevent this, in FIGS. 1 to 3, the solenoid valve 10 in the middle of the drainage hose 9 is turned on / off via the drainage hose 9 connected to the end portions 19B and 27B of the humidification unit, and Water is intermittently drained according to the accumulated operation time of the air conditioner to remove impurities.

Further, the same effect can be obtained even if the amount of water transported by the pump 26 is increased from the normal amount and the water is overflowed from the humidifying unit end portions 19B and 27B without providing the solenoid valve 10 and the like. That is, by the time the supplied humidifying water reaches the humidifying unit end portions 19B and 27B, an appropriate amount of humidifying water is supplied so that the humidifying water is almost completely humidified into the air. When the supply conveyance amount is increased, the increased humidification water is drained together with the impurities accumulated in the humidification unit 1.

Since the humidity in the non-air-conditioned room at the time of heating changes momentarily with the temperature change, the air inlet 5 of the indoor unit 11
It is necessary to control the humidification according to the detection value of the humidity sensor 3 provided in the vicinity, but the pump 26 of the outdoor unit 21 is turned ON / OFF in conjunction with the detection value of the humidity sensor 3 or the motor of the pump 26 is controlled. If the amount of water supplied to the humidifying unit 1 is adjusted by controlling the rotation speed of the humidifying unit 1, the indoor humidity can be easily controlled.

Since the drain water of the outdoor heat exchanger is at a low temperature, dew condensation easily occurs on the surface of the drain tube 8 to the indoor unit 11. In particular, when the drain tube 8 passes through the indoor part, it is necessary to insulate the outside of the drain tube 8. Easy.
In the case where the auxiliary pipe 12 for the refrigerant is provided on the rear surface of the indoor unit 11, the drain tube 8 connected to the humidifying unit 1 is housed in the cylindrical heat insulating material 14 outside the auxiliary pipe 12, and the If this part is connected, the drain water can be conveyed so that the construction becomes easier.

Since the vicinity of the humidifying unit 1 is always in a humid state, molds are easily generated, giving off odor and causing propagation of mites. In order to prevent this, it is effective to apply or knead a resin component such as a moisture permeable membrane, a holder of a humidifying unit, a pipe, or the like to perform an antifungal treatment. As a fungicide, benzimidazole type, chloroxylenol type and the like are often used.

[0053]

As described above, the air conditioner having a humidifying function according to the present invention is humidified by using the humidifying unit composed of a non-porous moisture permeable membrane. Hygiene humidification is possible because the water of water molecules is released, and the maintenance-free humidification function saves the trouble of water supply because the drain water of the outdoor unit is transported to the indoor unit to make up humidification water. Can be provided , and

According to a second aspect of the present invention, the humidifying unit is constituted by a plurality of hollow fiber-shaped moisture-permeable membrane aggregates, and a meandering cylindrical non-porous moisture-permeable membrane having an oval cross section. Further, by subjecting the non-porous moisture-permeable membrane to surface treatment by electric flocking or the like, the evaporation area can be increased and the humidification efficiency can be improved.

According to the fifth aspect of the invention, the intermittent drainage means for intermittently overflowing a part of the replenishing water to the humidifying unit from the end of the humidifying unit can flow out and remove impurities accumulated in the moisture permeable membrane of the humidifying unit. .

According to a sixth aspect of the present invention, the amount of drain water conveyed from the outdoor unit is controlled by controlling ON / OFF of a pump which is a makeup water conveying means, or by controlling the number of revolutions of the motor of the pump. Can be controlled.
