[0002]

2. Description of the Related Art Conventionally, there is a humidifying device for humidifying using a porous module formed of a hydrophobic porous membrane (Japanese Patent Laid-Open No. 11-3517).
No. 31). This humidifier increases the humidification amount per unit area of the hydrophobic porous membrane of the porous module by heating water stored in the tank with an electric heater to increase the temperature of water supply. However, in the above humidifier,
Since the supply water temperature is raised by using the electric heater, if the humidification amount increases, the power consumption of the electric heater increases, so that there is a disadvantage that the efficiency is low. In addition, since the humidifier uses heating by an electric heater, the water stored in the tank cannot be cooled, and a deodorizing function using cold water cannot be added. Therefore, even if such a humidifier is used in an air conditioner for cooling and heating, a low power consumption air conditioner having a humidifying function cannot be realized, and a deodorizing function using cold water cannot be provided.

An object of the present invention is to provide an air conditioner that can reduce power consumption and has a humidifying function with an excellent deodorizing function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an air conditioner having a humidifying function according to the present invention will be described in detail with reference to the illustrated embodiments.

(First Embodiment) FIG. 1 is a schematic structural view of an air conditioner having a humidifying function according to a first embodiment of the present invention, wherein 1 is a hydrophobic porous module, and 2 is a hydrophobic porous module 1.

Solenoid valve. The water supply means is constituted by the water supply pipe L3 and the float switch 5, and the water discharge means is constituted by the drainage pipe L4 and the solenoid valve 6 for water discharge.

The air conditioner having the humidifying function includes a compressor 11, a four-way switching valve 12 connected to the discharge side of the compressor 11, and one end connected to the four-way switching valve 12. A first heat exchanger 13 arranged on the windward side of the hydrophobic porous module 1, a second heat exchanger having one end connected to the other end of the first heat exchanger 13 and arranged in the water storage tank 2 An expansion valve 15 having one end connected to the other end of the second heat exchanger 14 as pressure reducing means;
A third heat exchanger 16 having one end connected to the other end of the third heat exchanger 16; an accumulator 17 having one end connected to the other end of the third heat exchanger 16 and the other end connected to the suction side of the compressor 11. And a fan 18 for sending outdoor air to the third heat exchanger 16. The compressor 11, the four-way switching valve 12, the first heat exchanger 13, the second heat exchanger 14, the expansion valve 15, the third heat exchanger 1
6 and the accumulator 17 constitute a heat pump circuit.

The hydrophobic porous module 1 includes a plurality of cylinders 1a each having a flow path for flowing water in the water storage tank 2 formed by a hydrophobic porous membrane, and a header for connecting both ends of the plurality of cylinders 1a. 1b, 1b. The other end of the pipe L1 whose one end is connected to the lower part of the water storage tank 2 is connected to the lower header 1b of the hydrophobic porous module 1, and one end of the pipe L2 is connected to the upper header 1b of the hydrophobic porous module 1. Connect the other end of the pipe L2 to the storage tank 2
Located at the top. A circulation circuit is formed by the hydrophobic porous module 1, the water storage tank 2, the pump 3, the pipe L1, and the pipe L2.

In the air-conditioning apparatus having a humidifying function having the above-described structure, in the combined heating and humidifying operation in which heating and humidification are performed, the compressor 11 is operated by switching the four-way switching valve 12 to the position indicated by the solid line. The discharged refrigerant is condensed in the first and second heat exchangers 13 and 14 as condensers, and then decompressed by the expansion valve 15. Then, the decompressed refrigerant evaporates in the third heat exchanger 16 as an evaporator, and then returns to the suction side of the compressor 11 via the accumulator 17.
Then, the indoor air from the fan 13 is supplied to the first heat exchanger 1.
3 and the hot air is blown into the room through the hydrophobic porous module 1. Further, the water in the water storage tank 2 is heated by the second heat exchanger 14, and the pump 3 is operated to supply the hot water in the water storage tank 2 to the hydrophobic porous module 1 via the pipe L1. The hot water supplied to the hydrophobic porous module 1 returns to the water storage tank 2 via the pipe L2 through the channels in the plurality of cylinders 1a, and the hot water circulates.

At this time, water vapor is released from the inside of the cylinder 1a of the hydrophobic porous module 1 through the hydrophobic porous membrane to the air supplied from the fan 4 via the first heat exchanger 13 to perform humidification. Is During operation, the heating capacity of the heat pump circuit is controlled by controlling the operation frequency of the compressor 11, and hot water having a temperature optimal for humidification is supplied to the hydrophobic porous module 1.

During operation, the drainage solenoid valve 6 is opened for a predetermined time to drain the hard component dissolved in the water to prevent the hard components from being concentrated and the scale from being deposited, and the float switch 5 is turned on. Fresh water is supplied to the water storage tank 2 via the water supply pipe L3, and when a predetermined water level is reached, the float switch 5 is turned off.

On the other hand, in the combined cooling and deodorizing operation for cooling and deodorizing, when the four-way switching valve 12 is switched to the position indicated by the dotted line and the compressor 11 is operated, the refrigerant discharged from the compressor 11 is used as a condenser. After being condensed in the third heat exchanger 16,
The pressure is reduced by the expansion valve 15. Then, the decompressed refrigerant evaporates in the first and second heat exchangers 13 and 14 as evaporators and returns to the suction side of the compressor 11 via the accumulator 17. Then, the indoor air from the fan 13 is
The air is cooled by the heat exchanger 13 and the cold air is blown into the room through the hydrophobic porous module 1. Further, the water in the water storage tank 2 is cooled by the second heat exchanger 14, and
Operate the pump 3 to supply the cold water in the water storage tank 2 to the pipe L
1 to the hydrophobic porous module 1. The cold water supplied to the hydrophobic porous module 1 returns to the water storage tank 2 via the pipe L2 through the channels in the plurality of cylinders 1a, and the cold water circulates.

At this time, the cold water passing through the inside of the cylinder 1a of the hydrophobic porous module 1 passes through the hydrophobic porous membrane forming the cylinder 1a, and the odor component (or gas component) from the air supplied from the fan 4 Is absorbed and deodorized. During operation, the cooling capacity of the heat pump circuit is controlled by controlling the operation frequency of the compressor 11, and cold water having a temperature optimal for deodorization is supplied to the hydrophobic porous module 1.

During operation, odorous gas or VOC (Volatil
In order to prevent the dissolved concentration of e Organic Compoubd (volatile organic compound) and the like from gradually increasing due to absorption, and to reduce the absorption performance, the drain switch 6 is opened for a predetermined time to drain the water, and the float switch 5 When it is turned on, new water is supplied to the water storage tank 2 via the water supply pipe L3, and when a predetermined water level is reached, the float switch 5 is turned off. Thus, the absorption performance (deodorization and degassing) is restored by discharging the water with the increased concentration in the water storage tank 2 and replacing it with new water. By sharing the scale drainage control during the humidification operation and the gas dissolution drainage control during the deodorization operation, a cost increase can be prevented.

The degree of dissolution of odorous gas and VOC components in water is indicated by Henry's constant, and the smaller the Henry's constant, the easier it is to dissolve in water. This Henry's law constant decreases as the temperature of the water decreases. For example, Figure 16 shows the characteristics of the Henry's constant with respect to the temperature change of the ammonia (NH ₃₎ (horizontal axis the temperature, the vertical axis Henry's constant), as is clear from FIG. 16, ammonia (NH ₃₎ is at a temperature The lower the value, the smaller the size, and other odorous gases and VOC components have the same tendency. As described above, the Henry's constant decreases as the temperature of the water decreases, and the odorous gas and the VOC component are easily dissolved in the water. Therefore, the deodorizing performance can be improved by using cold water. Also, as the temperature of the water is lower, the pressure difference between the water vapor partial pressure on the cold water side and the water vapor partial pressure of the air becomes smaller, so that the water vapor is less likely to be released into the air,
Humidification performance decreases.

As shown in Table 1, the Henry's law varies greatly depending on the type of gas.

[Table 1]

For example, the degree of dissolution of ammonia (H
= 0.00005) as 100%, the amount of trimethylamine decreases to about 1/16, and the degassing performance decreases.
The drainage interval for replacing the water in the water storage tank may be increased 16 times. Therefore, the characteristics of water, air smell, VOC, etc. change at the place where the apparatus is installed, so that an appropriate drainage interval can be set by remote control operation according to the user's request.

As described above, in the air conditioner having the humidifying function of the first embodiment, the heating operation and the cooling operation are performed by heating and cooling the indoor air by the first heat exchanger 13, and the heat efficiency is improved. Since the hot water heated by the second heat exchanger 14 of the good heat pump circuit is supplied to the hydrophobic porous module 1 to perform humidification, power consumption can be reduced.

Further, since the second heat exchanger 14 of the heat pump circuit has a cooling function in addition to a heating function, it uses water cooled by the heat pump circuit with high heat efficiency to provide an excellent deodorizing effect with high energy saving effect. Functions can be provided.

By arranging the second heat exchanger 14 of the heat pump circuit in the water storage tank 2, the water in the water storage tank 2 can be efficiently heated or cooled.

Further, by arranging the first heat exchanger 13 on the windward side of the hydrophobic porous module 1, the room air heated or cooled via the first heat exchanger 13 is transferred to the hydrophobic porous module 1. Since it can be supplied, the efficiency of humidification or deodorization by the hydrophobic porous module 1 is improved.

The water in the water storage tank 2 is circulated by the pump 3 through the flow path in the cylinder 1 a of the hydrophobic porous module 1, so that the water whose temperature has been adjusted by the second heat exchanger 14 becomes hydrophobic. Can be continuously supplied to the porous module 1. Further, by circulating the water in the water storage tank 2 through the flow path of the porous module 1 at the time of deodorization, it is possible to suppress an increase in the concentration of the odor component absorbed by the water in the porous module 1.

The water in the water storage tank 2 is drained.
(Drainage pipe L4, electromagnetic valve 6 for drainage) and then water is supplied into water storage tank 2 by water supply means (water supply pipe L3, float switch 5), so that the concentration of the hard component becomes too high by the humidification operation. While the water in the water storage tank 2 can be replaced so that scale does not occur, the water in the water storage tank 2 is replaced so that the concentration of the odorous component does not become too high due to the deodorizing operation and the deodorizing ability does not decrease. Can be.

[Heating operation mode] (1-1) Combined heating and humidification operation In the combined heating and humidification operation, when the four-way switching valve 92 is switched to the position indicated by the solid line to operate the compressor 91, the discharge from the compressor 91 is performed. After the refrigerant is condensed in the first and second heat exchangers 93 and 94 as the condenser, the pressure is reduced by the first expansion valve 95. Then, the decompressed refrigerant evaporates in the third heat exchanger 96 as an evaporator, and then returns to the suction side of the compressor 91 via the accumulator 97. Then, fan 84
Is heated by the first heat exchanger 93, and the warm air is blown into the room through the hydrophobic porous module 81. Further, the water storage tank 82 is controlled by the second heat exchanger 94.
While heating the water inside, the pump 83 is operated to supply the hot water in the water storage tank 82 to the hydrophobic porous module 81 via the pipe L51. The above-mentioned hydrophobic porous module 8

In this case, water vapor is released from warm water passing through the inside of the cylinder 81a, through the hydrophobic porous membrane of the cylinder 81a, and into the air supplied from the fan 84 via the first heat exchanger 93, and humidification is performed. During operation, the heating capacity of the heat pump circuit is controlled by controlling the operation frequency of the compressor 91, and hot water having a temperature optimal for humidification is supplied to the hydrophobic porous module 81.

During the combined heating and humidification operation, the drainage solenoid valve 86 is opened for a predetermined period of time to drain the hard component dissolved in the water and to prevent the scale from depositing. 86, the solenoid valve 85 for water supply is opened to supply new water to the water storage tank 82, and the water level sensor 1
When the water level detected by 00 becomes a predetermined water level, the water supply solenoid valve 85 is closed.

(1-2) Heating alone operation The pump 83 is stopped, the water supply solenoid valve 85 is closed, the drainage solenoid valve 86 is opened, and the water in the water storage tank 82 is discharged. By performing the same operation as “1-1) combined heating and humidification operation”, only the heating operation is performed by the heat radiation of the first heat exchanger 93.

(1-3) Deodorization Standalone Operation When the temperature of the water in the water storage tank 82 is sufficiently low to be used for deodorization, the compressor 91 is stopped, the pump 83 is operated, and the water in the water storage tank 82 is operated. By circulating water through the hydrophobic porous module 81, only deodorization is performed. In addition, if the odor of indoor air and other gases are absorbed, the concentration of water contamination will increase and the deodorizing performance will decrease.
After the drainage solenoid valve 86 is opened for a predetermined time to drain the water having an increased concentration in the water storage tank 82, the drainage solenoid valve 86 is closed, and the water supply solenoid valve 85 is opened to supply new water to the water storage tank 82. Then, when the water level detected by the water level sensor 100 reaches a predetermined water level, the water supply solenoid valve 85 is closed.

[Cooling operation mode] (2-1) Combined cooling and deodorizing operation In the combined cooling and deodorizing operation, when the four-way switching valve 92 is switched to the position indicated by the dotted line to operate the compressor 91, the discharge from the compressor 91 is performed. After the refrigerant is condensed in the third heat exchanger 96 as a condenser, the pressure is reduced by the first expansion valve 95. Then, the decompressed refrigerant evaporates in the first and second heat exchangers 93 and 94 as evaporators, and then returns to the suction side of the compressor 91 via the accumulator 97. Then, fan 84
From the room is cooled by the first heat exchanger 93,
The cold air is blown into the room through the hydrophobic porous module 81. The water in the water storage tank 82 is cooled by the second heat exchanger 94, and the pump 83 is operated to supply the cold water in the water storage tank 82 to the hydrophobic porous module 81 via the pipe L51. The cold water supplied to the hydrophobic porous module 81 returns to the water storage tank 82 via the pipe L52 through the channels in the plurality of cylinders 81a, and the cold water circulates.

At this time, the hydrophobic porous module 81
Then, the odor component (or gas component) in the air supplied from the fan 84 is absorbed by the cold water in the cylinder 81a through the hydrophobic porous membrane of the cylinder 81a, and deodorization is performed. During operation, the cooling capacity of the heat pump circuit is controlled by controlling the operation frequency of the compressor 91, and cold water having a temperature optimal for deodorization is supplied to the hydrophobic porous module 81.

When the water temperature of the hydrophobic porous module 81 detected by the temperature sensor 104 is continuously lower than the lower limit temperature (= dew point temperature + predetermined temperature) for a predetermined time or more, the drainage solenoid valve 86 is opened to store water. After draining the tank 82, the water supply solenoid valve 85 is opened to supply water to the water storage tank 82,
The water temperature of the hydrophobic porous module 81 is kept below the lower limit temperature continuously for a certain time or more. Further, even if the water in the water storage tank 82 is replaced, if the temperature is continuously lower than the lower limit temperature (= dew point temperature + predetermined temperature) for a certain period of time or more, the operating frequency of the compressor 91 is reduced to thereby perform the second heat exchange. The cooling amount of the vessel 94 is reduced so that the water temperature of the hydrophobic porous module 81 does not fall below the lower limit temperature continuously for a certain time or more. By doing so, dew condensation on the hydrophobic porous membrane of the hydrophobic porous module 81 can be prevented,
It is possible to prevent a reduction in efficiency due to condensation.

Further, during operation, odorous gas or VOC (Volatil
e) The drainage / drain solenoid valve 86 is opened for a predetermined period of time to drain the organic compound (volatile organic compound), etc., in order to prevent the penetration concentration from gradually increasing due to the absorption and lowering the absorption performance. Close the solenoid valve 86, open the water supply solenoid valve 85 and supply new water to the water storage tank 82,
When the water level detected by the water level sensor 100 reaches a predetermined water level, the water supply solenoid valve 85 is closed. Thus, the absorption performance (deodorization and degassing) is restored by discharging the water with the increased concentration in the water storage tank 82 and replacing it with new water.

(2-2) Cooling alone operation The pump 83 is stopped, the water supply solenoid valve 85 is closed, the drainage solenoid valve 86 is opened, and the water in the water storage tank 82 is reduced. 2-1) Cooling / deodorizing combined operation ”, whereby only the cooling operation is performed by absorbing heat of the first heat exchanger 93.

(2-3) Deodorizing Priority Operation In the deodorizing independent operation, the same operation as “(2-1) Combined cooling and deodorizing operation” is performed. In that the machine 91 is stopped. That is, the first heat exchanger 9 of the heat pump circuit
The deodorization is performed prior to the cooling while limiting the cooling capacity of the cooling device.

As described above, in the air conditioner having the humidifying function of the fifth embodiment, the heating operation and the cooling operation are performed by heating and cooling the indoor air by the first heat exchanger 93, and the heat efficiency is improved. Since the hot water heated by the second heat exchanger 94 of the good heat pump circuit is supplied to the hydrophobic porous module 1 for humidification, power consumption can be reduced.

Since the second heat exchanger 94 of the heat pump circuit has a cooling function in addition to a heating function, the second heat exchanger 94 uses water cooled by the heat pump circuit having high heat efficiency to provide excellent deodorization with high energy saving effect. Functions can be provided.

Further, by disposing the second heat exchanger 94 of the heat pump circuit in the water storage tank 82, the water in the water storage tank 82 can be efficiently heated or cooled.

Further, by disposing the first heat exchanger 93 on the windward side of the hydrophobic porous module 81,
Since the heated or cooled room air can be supplied to the hydrophobic porous module 81 via the heat exchanger 93, the efficiency of humidification or deodorization by the hydrophobic porous module 81 is improved.

Further, the water in the water storage tank 82 is circulated by the pump 83 through the flow path in the cylinder 81a of the hydrophobic porous module 81, so that the second heat exchanger 9
4. The water whose temperature has been controlled by
Can be supplied continuously. Further, by circulating the water in the water storage tank 2 through the flow path of the porous module 1 at the time of deodorization, it is possible to suppress an increase in the concentration of the odor component absorbed by the water in the porous module 1.

After the water in the water storage tank 82 is drained by drainage means (drainage pipe L54, drainage solenoid valve 86), water is supplied into the water storage tank 82 by water supply means (water supply pipe L53, water supply solenoid valve 85). By supplying the water, the water in the water storage tank 82 can be replaced so that the concentration of the hard component does not become too high due to the humidification operation and the scale is not generated, while the concentration of the odor component becomes too high by the deodorization operation In order to prevent the deodorizing ability from decreasing, the water storage tank 82
The water inside can be replaced.
