The fresh air is further cooled and dehumidified by a cooler 46 and a drain separator 48 and is introduced into a separation module 54. Separated oxygen rich air is sucked into an air pump 26, and fed to a nozzle 22 and blown out into a phytoncide 16. Thus, vaporized perfume fluid is stably supplied into an air supply system.

Description

[Detailed Description of the Invention] [Industrial Field of Application] Fuhatsumon relates to air conditioners with aroma devices, and in particular mixes aromatic air with the conditioned air from air conditioners installed in intelligent buildings, etc., which is similar to forest bathing. This invention relates to an air conditioner with an aroma device that creates an air-conditioned environment.

[Conventional technology]

Recent intelligent buildings are equipped with many computer network systems, office automation equipment, etc. due to advanced information technology. Along with this, employees working in the building tend to experience increased stress due to the complexity of OA work and other work.

In order to relieve this stress during working hours and create a more comfortable working environment, we are developing air conditioning systems (hereinafter referred to as air conditioning) in buildings that go beyond conventional temperature and humidity control. , it is desired to create an air-conditioned environment similar to that of forest bathing.

The forest bathing environment is said to be very good for mental health because it can relieve stress and prevent fatigue.

By the way, as a method to create an air-conditioned environment similar to that of forest bathing, phytoncide (an aromatic substance emitted by plants that has sterilizing and insect repellent properties) that characterizes forest bathing is artificially created, and this phytoncide is added to the air supply system of the air conditioner. There is a way to supply it. Currently, essential oil extracted from trees such as Japanese cypress is used as the phytonchi 7), and the aroma I raw gas obtained by heating and evaporating this essential oil is supplied to the air supply system of the air conditioner.

Another method for creating an air-conditioned environment similar to forest bathing is to supply conditioned air with a high oxygen concentration. This method supplies oxygen enriched by an oxygen concentration enrichment device using membrane separation into the air supply system.

However, the method using phytoncide is characterized in that the amount of phytoncide evaporated is proportional to the evaporation area and heating temperature. Therefore, as the air conditioner becomes larger, the heating device must also be larger, and as the device becomes larger, the cost becomes enormous.

A device shown in FIG. 3 has been proposed as an air conditioner for eliminating such problems.

According to FIG. 3, this air conditioner with aroma device 10 is composed of a fragrance device 12 and an air conditioner 14.

A container 18 in which phytoncide 16 is stored is installed in the aroma device 12, and a dimension heater 20 is removed from the outer peripheral surface of this container 18. immersed and mounted;
This nozzle 22 is connected to an air filter 28 via a mass flow controller 24 and an air pump 26. Therefore, by operating the air pump 26, outside air is sucked from the air filter 23 and the mass flow controller 2
4 and is blown out from the nozzle 22 to the phytoncide 16. This promotes the evaporation action of phytoncide 16, so that a large amount of phytoncide 16 can be evaporated with a compact device.

In addition, a liquid level gauge 3 is provided near the inner bottom and at the top of the container 18.
0.32 is installed. The ceiling of the container 18 is communicated with an air conditioning duct 36 via a solenoid valve 34. Therefore, by opening the electromagnetic valve 34, the phytoncide 16 evaporated in the container 18 can be supplied to the air conditioning duct 36. The air conditioning duct 36 is connected to the air conditioner 14 described above, and air conditioned air from the air conditioner 14 is supplied in the direction of the arrow in the figure. As a result, the evaporated phytoncide 16 is mixed with the conditioned air and supplied to each room in the building (not shown).

(Problem that development is trying to solve) However, in the conventional air conditioner equipped with an aroma device, the nozzle 2
The disadvantage is that the nozzle 22 must be replaced or repaired periodically as it frequently becomes clogged.

Furthermore, if the nozzle 22 becomes clogged and the amount of air blown out from the nozzle 22 decreases, the amount of hub links (air bubbles) decreases, so that the phytoncide 16 evaporated from the container 18 is not supplied to the air conditioning duct 36. There is a drawback that dew condenses on piping, etc. As a result, the supply of phytoncide 16 is insufficient, so there is a drawback that an air-conditioned environment similar to that of a forest bathing environment cannot be created.

The present invention (made in view of the above circumstances) provides an air conditioner with an aroma device that can prevent nozzle clogging and stably supply evaporated phytoncide into an air supply system. With the goal.

[Means to solve problems]

In order to achieve the above-mentioned object, the present invention provides a drain container for storing an aromatic liquid;
air enrichment means (48, 54) for separating oxygen from this outside air to obtain nitrogen-enriched air; and air supply means (48, 54) for supplying the nitrogen-enriched air to the aromatic liquid in the container (18).
22), heating means (20) for heating the container (18) to evaporate the aromatic liquid, and supplying the aromatic air evaporated by the heating means (20) into an air supply system of an air conditioner. According to the present invention, the cause of clogging of the air supply means (22) is as follows: Oxygen in the air blown out from the air supply means (22) oxidizes components in the aromatic liquid (16), which adheres to the air supply means (22) and hardens; Note that the reason why the evaporated aromatic liquid 16) condenses is due to the high humidity in the air blown out from the air blowing means (22), and the air blowing means (22) is provided with: Air enrichment means (48, 54) dehumidify and supply nitrogen-enriched air from which oxygen has been separated.

A pressure gauge 56 is attached to the connection line between the electromagnetic valve 50 and the filter unit 52, and the pressure gauge 56 measures the atmospheric pressure of the outside air passing through the connection line. Further, a thermometer 58 is attached to the connection line between the filter unit 52 and the separation module 54, and the temperature of the outside air is measured by this thermometer 58.

By the way, the outside air sent into the separation module 54 is separated into oxygen-enriched air and nitrogen-enriched air by the separation membrane of the separation module 54. The separated oxygen-enriched air is sucked into the air pump 61 by opening the electromagnetic tube 59, and is supplied to the air conditioning duct 36 as shown by the arrow in the figure. Further, the atmospheric pressure and flow rate of the oxygen-enriched air are measured by a pressure gauge 60 and a flow rate H62.

On the other hand, the separated nitrogen-enriched air is supplied to the above-mentioned aroma device 42 via the duct 64.

Maegonmi tact 64 is air pump 26, mass flow controller)
It is connected to the nostle 22 via the o-ra 24 and the electromagnetic hull pro 5. The nozzle 22 is placed so as to be immersed in the phytoncide 16 stored in the container 18. Therefore, the nitrogen-enriched air sent to the tact 64 is
After being sucked into the air pump 26 , the air passes through the mass flow controller 24 to be adjusted to a constant flow rate, and is blown out from the tip of the nostle 22 to the phytoncide 16 . The blown nitrogen-enriched air becomes bubbles and rises inside the container 18, evaporates from the water surface of the phytoncide 16, and promotes evaporation of the phytoncide 16.

A heater 20 and a temperature sensor 21 are installed on the outer periphery of the container 18.
The container 18 is heated by the heater 2o, and the evaporation action of the phytoncide 16 is promoted. Further, the ceiling portion of the container 18 is communicated with the above-mentioned air conditioning tact 36 via a solenoid valve 34. Therefore, by opening the solenoid valve 34, the evaporated phytoncide 16 is supplied to the air conditioning tact 36 as indicated by the arrow in the figure, and mixed with the oxygen-enriched air previously supplied by the air conditioner 40.

Further, liquid level gauges 30 and 32 are attached to the container 18.

The bottom of the container 18 is communicated with a solution tank 72 in which phytoncide 16 is stored via a solenoid valve 68 and a liquid feed pump 70, and is also communicated with a drain tank 76 via a solenoid valve 74.

Next, the operation of the air conditioner with aroma device configured as described above will be explained.

First, in order to store phytoncide 16 in the empty container 18, the sequence controller 78 sends a signal to the water pump 70 to operate the water pump 70, and also sends a signal to the electromagnetic valve 68 to open the electromagnetic valve 68. As a result, the phytoncide 16 stored in the liquid tank 72 is absorbed by the water pump 70 and supplied to the container 18. still,
At this time, the compressor 44 of the air conditioner 40 is stopped, and the solenoid valve 74 of the air conditioning device 42 is also closed. Once rising, a signal is sent to the sequence controller 78 indicating that the water level has risen. When the sequence controller 78 receives the lava, it transmits a signal to stop the water pump 70 and a signal to close the solenoid valve 68 based on this signal. Next, the /- control unit 78 sends a signal to operate the compressor 44 and sends a signal to open the solenoid valves 50 and 65. As a result, the outside air is sucked and compressed by the compressor 44. , further cooler 48, drain separator 4

Further, the nitrogen-enriched air separated by the separation module 54 is sucked by the air pump 26j of the aroma device 42 and supplied to the nostle 22 via the mass flow controller 24.71i and the magnetic valve 65.

The nitrogen-enriched air supplied to the nozzle 22 is blown out onto the phytoncide stored in the container 18. Therefore,
Since the air passing through the nozzle 22 is nitrogen-enriched air from which oxygen has been separated, clogging of the nozzle 22 caused by oxygen can be prevented. In addition, phytoncide 1

It is possible to prevent dew condensation from forming on the pipes halfway up to 6.

Therefore, according to this embodiment, clogging of the nostle 22 can be prevented and the evaporated phytoncide 16 can be stably supplied to the air conditioning duct 36.

Furthermore, since the air conditioning duct 36 is supplied with oxygen-enriched air from the air conditioner 40, it is possible to easily create an air-conditioned environment similar to that of forest bathing, which requires a high concentration of oxygen.
