Since the sensible heat exchange is performed between the two, the air supplied to the indoor space S can be reheated to an appropriate temperature while being maintained in a low humidity state. On the other hand, during the humidification operation in winter, the sensible heat exchanger 102 exchanges sensible heat between the outdoor air that has passed through the total heat exchanger 101 and the hot and humid air that has passed through the humidity control device 103. The air supplied to the indoor space S can be cooled to an appropriate temperature while being maintained in a humid state.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a schematic configuration of an air conditioning system 1 according to an embodiment of the present invention.

It is provided with a replaceable sensible heat exchanger 3 and a humidity control device 4 for adjusting the humidity and temperature of air.

Further, the air conditioning system 1 includes an outside air flow path 5, a ring air flow path 6, a supply air flow path 7, and an air flow path 7 in order to construct a cycle of controlling the humidity and temperature of the indoor space S and ventilating the indoor space S. It further includes an exhaust flow path 8. In FIG. 1, OA refers to the air drawn into the indoor space S from the outside, RA refers to the air drawn from the indoor space S into the humidity control device 4, and SA is sent from the humidity control device 4 to the indoor space S. EA refers to the air sent out from the indoor space S to the outside. Further, in FIG. 1, reference numerals 9 and 10 are temperature sensors and humidity sensors provided in the indoor space S, and reference numerals 11A to 11C are connected to the outside air flow path 5, the exhaust flow path 8 and the supply air flow path 7, respectively. It is a fan (blower). The fan 11C may be connected to the ring air flow path 6.

The outside air flow path 5 is a line that introduces outdoor air into the indoor space S via the total heat exchanger 2 and the sensible heat exchanger 3. After guiding the outdoor air to the total heat exchanger 2, the sensible heat exchanger 2. The outdoor air after total heat exchange is guided to 3, and the outdoor air after actual heat exchange is guided to the indoor space S. The ring air flow path 6 is a line that supplies the air in the indoor space S to the humidity control device 4. The air supply flow path 7 is a line that supplies air (conditioned air) whose temperature and humidity have been adjusted by the humidity control device 4 to the indoor space S via the sensible heat exchanger 3. The exhaust flow path 8 is a line that exhausts the air in the indoor space S to the outside through the total heat exchanger 2. In the air conditioning system 1 of the present embodiment, the discharge port in the indoor space S of the outside air flow path 5 is arranged in the vicinity of the suction port in the indoor space S of the ring air flow path 6. The "neighborhood" refers to a distance of about 150 mm to 300 mm from each other. The discharge port in the indoor space S of the outside air flow path 5 and the suction port in the indoor space S of the ring air flow path 6 do not necessarily have to be arranged in the vicinity.

The total heat exchanger 2 is a device that exchanges sensible heat and latent heat between the outdoor air guided by the outside air flow path 5 and the air in the indoor space S guided by the exhaust flow path 8.

The sensible heat exchanger 3 is sensible heat between the outdoor air that has passed through the total heat exchanger 2 and is guided by the outside air flow path 5 and the harmonious air that has passed through the humidity control device 4 and is guided by the air supply flow path 7. It is a device that exchanges heat.

The humidity control device 4 is a device for adjusting the temperature and humidity of the air in the indoor space S, and includes a refrigerant coil 40 and a humidifier 41. The refrigerant coil 40 is a device that heats or cools air by exchanging heat between the air passing through the surface and the refrigerant flowing inside. The humidifier 41 is a device that vaporizes water such as tap water to increase the humidity in the air, and for example, a vaporization type humidifier can be used. The humidifier 41 is operated as needed. For example, when air humidification is not required in summer or the like, the air that has passed through the refrigerant coil 40 is humidified without operating the humidifier 41. It passes through the vessel 41 and is guided to the sensible heat exchanger 3.

Next, the dehumidifying operation in summer and the humidifying operation in winter in the air conditioning system 1 of the present embodiment will be described.

First, the dehumidifying operation in summer will be described. First, the outdoor air is guided to the total heat exchanger 2 by the outside air flow path 5. The outdoor air exchanges total heat with the air in the indoor space S guided to the total heat exchanger 2 via the exhaust flow path 8. Since the outdoor air in summer is hot and humid and the air in the indoor space S has a lower temperature and humidity than the outdoor air, the outdoor air is in a state where the temperature and humidity are lowered by heat exchange in the total heat exchanger 2.

Next, the outdoor air whose temperature and humidity have decreased is guided to the sensible heat exchanger 3 by the outside air flow path 5, and sensible heat exchange is performed with the conditioned air that has passed through the humidity control device 4. Since the conditioned air that has passed through the humidity control device 4 has a low temperature and low humidity as described later, the outdoor air guided from the total heat exchanger 2 is cooled by heat exchange in the sensible heat exchanger 3 and has an absolute humidity. Only the temperature is further lowered while maintaining the above, and the temperature is guided to the indoor space S.

Next, the air in the indoor space S is guided to the humidity control device 4 by the ring air flow path 6. When the dehumidifying operation is performed in the humidity control device 4, a low temperature refrigerant (including cold water) is supplied to the refrigerant coil 40 to make the refrigerant coil 40 function as a cooling coil. As a result, the air sent from the indoor space S is overcooled on the surface of the refrigerant coil 40, and as a result, the moisture (humidity) contained in the air is condensed into condensed water, so that the air has passed through the refrigerant coil 40. The air is low temperature and low absolute humidity. The removed water (humidity) is discharged to the outside from a drain (not shown). During the dehumidifying operation, the air that has passed through the refrigerant coil 40 is supplied to the sensible heat exchanger 3 as it is without operating the humidifier 41.

The low-temperature and low-humidity air adjusted by the humidity control device 4 is guided to the sensible heat exchanger 3 by the air supply flow path 7, and is heated by the heat exchange in the sensible heat exchanger 3 described above, and only the temperature is maintained while maintaining the low humidity. It is supplied to the indoor space S in a state of being appropriately raised. As a result, the humidity of the air in the indoor space S can be lowered and the temperature can be lowered.

When the air in the indoor space S is affected by the heat and water vapor generated by a person living in the indoor space S and the heat generated by a personal computer and audio equipment arranged therefor a long time, both the temperature and humidity rise. The air in the indoor space S is discharged to the outside by the exhaust flow path 8, but before the exhaust, the total heat is exchanged with the outdoor air guided by the total heat exchanger 2 and guided by the outside air flow path 5. By doing so, the air is discharged to the outside in a state where the temperature and humidity are increased.

During the dehumidification operation described above, the temperature of the air passing through the humidity control device 4 and being guided to the sensible heat exchanger 3 by controlling the temperature and flow rate of the low-temperature refrigerant supplied to the refrigerant coil 40 of the humidity control device 4 And humidity can be changed. Therefore, the temperature and humidity of the air supplied to the indoor space S can be easily controlled, and the indoor space S can be set to an appropriate temperature and humidity. Further, since the outdoor air is taken into the indoor space S by the outside air flow path 5 and the air in the indoor space S is discharged to the outside by the exhaust flow path 8, the indoor space S can be ventilated.

Next, the humidifying operation in winter will be described. First, the outdoor air is guided to the total heat exchanger 2 by the outside air flow path 5. The outdoor air exchanges total heat with the air in the indoor space S guided to the total heat exchanger 2 via the exhaust flow path 8. Since the outdoor air in winter is low temperature and low humidity, and the indoor space S guided by the exhaust flow path 8 has a higher temperature and humidity than the outdoor air, the outdoor air guided by the outdoor air flow path 5 has a temperature and humidity. Is in an elevated state.

Next, the outdoor air whose temperature and humidity have been increased is guided to the sensible heat exchanger 3 by the outside air flow path 5, and sensible heat exchange is performed with the conditioned air that has passed through the humidity control device 4. Since the conditioned air that has passed through the humidity control device 4 has a high temperature and high humidity as described later, the outdoor air guided from the total heat exchanger 2 is heated by the heat exchange in the sensible heat exchanger 3 and is absolutely It is guided to the indoor space S in a state where only the temperature is further increased while maintaining the humidity.

Next, the air in the indoor space S is guided to the humidity control device 4 by the ring air flow path 6. When the humidifying operation is performed in the humidity control device 4, a high-temperature refrigerant (including hot water) is supplied to the refrigerant coil 40 to make the refrigerant coil 40 function as a heating coil, and the humidifier 41 releases water vapor into the air. Add. As a result, the air sent from the indoor space S is heated on the surface of the refrigerant coil 40, and then water vapor is supplied by the humidifier 41, resulting in high temperature and high absolute humidity.

The hot and humid air adjusted by the humidity control device 4 is guided to the sensible heat exchanger 3 by the air supply flow path 7, cooled by the heat exchange in the sensible heat exchanger 3 described above, and only the temperature is maintained while maintaining high humidity. It is supplied to the indoor space S in a moderately lowered state. As a result, the humidity of the air in the indoor space S can be increased and the temperature can be increased.

When the air in the indoor space S is affected by the heat and water vapor generated by a person living in the indoor space S and the heat generated by a personal computer and audio equipment arranged therefor a long time, both the temperature and humidity rise. The air in the indoor space S is discharged to the outside by the exhaust flow path 8, but before the exhaust, the total heat is exchanged with the outdoor air guided by the total heat exchanger 2 and guided by the outside air flow path 5. By doing so, the air is discharged to the outside in a state where the temperature and humidity are lowered.

Even during the humidification operation described above, the temperature of the air passing through the humidity control device 4 and being guided to the sensible heat exchanger 3 by controlling the temperature and flow rate of the high temperature refrigerant supplied to the refrigerant coil 40 of the humidity control device 4 And humidity can be changed. Therefore, the temperature and humidity of the air supplied to the indoor space S can be easily controlled, and the indoor space S can be set to an appropriate temperature and humidity. Further, since the outdoor air is taken into the indoor space S by the outside air flow path 5 and the air in the indoor space S is discharged to the outside by the exhaust flow path 8, the indoor space S can be ventilated.

Further, according to the air conditioning system 1 of the present embodiment described above, the outdoor air is once guided to the indoor space S after passing through the total heat exchanger 2 and the sensible heat exchanger 3 by the outside air flow path 5. The air in the indoor space S is guided to the humidity control device 4 by the ring air flow path 6, and the conditioned air after temperature control and humidity control is supplied to the indoor space S by the air supply flow path 7. Therefore, for example, in the summer, the indoor space S in a state where the air conditioning is stopped for a long time and the temperature is considerably high can be quickly cooled. This point will be described below.

In the conventionally known air conditioning system 100 as shown in FIG. 4, for example, in summer, the humidity control device 103 generates low-temperature and low-humidity air, so that the air supplied to the indoor space S has low humidity. Although it is in a state, the temperature is in a high state (for example, about 25 ° C. to 28 ° C.) due to heat exchange in the sensible heat exchanger 102. Further, in the conventional air conditioning system 100 shown in FIG. 4, ventilation, temperature control, and humidity control are always linked, and the temperature control and humidity control outside air is supplied to the indoor space S to provide an indoor space. The temperature of S is adjusted. Therefore, the start-up of air conditioning is slow, and it takes time to cool the indoor space S. In order to avoid such a situation and quickly cool the temperature of the indoor space S to a comfortable state, it is necessary to further lower the temperature of the air generated by the humidity control device 103, but the operation of the refrigerant coil 105 The load increases and the energy efficiency becomes poor.

On the other hand, in the air conditioning system 1 of the present embodiment, since ventilation, temperature control, and humidity control are independent, only the temperature control and humidity control of the indoor space S can be performed. That is, in the air conditioning system 1 of the present embodiment, the fans 11A and 11B are stopped and only the fan 11C is operated, so that the outdoor air to the total heat exchanger 2 and the sensible heat exchanger 3 by the outside air flow path 5 is operated. The air in the indoor space S is stopped from being taken in and the air in the indoor space S is discharged to the outside by the exhaust flow path 8, the air in the indoor space S is supplied to the humidity control device 4 by the sensible air flow path 6, and the conditioned air is indoors by the supply air flow path 7. Only the supply to the space S can be performed. As a result, the high temperature air in the indoor space S can be directly adjusted by the humidity control device 4, and the low temperature and low humidity air can be directly supplied to the indoor space S. As a result, the air conditioning starts up faster, so that even if the temperature of the indoor space S becomes considerably high, the indoor space S can be quickly opened without increasing the operating load of the humidity control device 4 (refrigerant coil 40). Can be cooled. As a result, a high energy saving effect can be obtained, and the running cost of the entire system can be reduced.

After that, when the temperature of the indoor space S drops to some extent (to a predetermined temperature), the fans 11A and 11B are operated to start taking in the outdoor air into the total heat exchanger 2 and the sensible heat exchanger 3. The indoor space S can be maintained in a comfortable temperature / humidity state, and the indoor space S can be ventilated.

Similarly, in the indoor space S in a state where the temperature is considerably low in winter, the indoor space S can be quickly heated by controlling the fans 11A to 11C.

Further, in the air conditioning system 1 of the present embodiment, as compared with the conventional air conditioning system 100 shown in FIG. 4, ventilation, temperature control, and humidity control are independent, so that the fans 11A and 11B are operated. By stopping the fan 11C and the humidity control device 4, only the ventilation of the indoor space S can be performed.

As described above, in the air conditioning system 1 of the present embodiment, ventilation, temperature control, and humidity control can be performed at the same time, or can be performed separately.

Further, in the air conditioning system 1 of the present embodiment, since the discharge port in the indoor space S of the outside air flow path 5 and the suction port in the indoor space S of the ring air flow path 6 are arranged in the vicinity, for example, outside in summer. Even if the high humidity outside air is taken into the indoor space S by the air flow path 5, the high humidity outside air can be quickly taken in by the ring air flow path 6 and the temperature and humidity can be controlled by the humidity control device 4.

Control of the temperature and flow rate of the refrigerant supplied to the refrigerant coil 40 of the humidifier 4 described above, operation control of the humidifier 41, operation control of the fans 11A to 11C, and the like are performed by a control device (not shown). The control device monitors the temperature and humidity of the indoor space S by the temperature sensor 9 and the humidity sensor 10, and controls each device according to an instruction from a controller (not shown) provided in the indoor space S to control the indoor space. S can be the desired environment.

Although one embodiment of the present invention has been described in detail above, the specific embodiment of the present invention is not limited to the above embodiment. For example, in the above embodiment, there is one indoor space S to be air-conditioned, but as shown in FIG. 2, a plurality of (three in the illustrated example) indoor spaces S1, S2, and S3 are to be air-conditioned. You can also.

Further, the outside air flow path 5 is branched into a plurality of first branch flow paths 50 via the distributor 12A, and the outdoor air is supplied to each indoor space via each sensible heat exchanger 3 by the respective first support flow paths 50. Lead to S1, S2, S3. Further, in the exhaust flow path 8, a plurality of second branch flow paths 80 are merged via the distributor 12B, and the air in each indoor space S1, S2, S3 is taken out by each of the second branch flow paths 80 and merges. Later, it is guided to the total heat exchanger 2 and discharged to the outside of the room. Electric dampers 15, 16 and the like are provided in the first branch flow path 50 and the second branch flow path 80, respectively. The opening / closing control of the electric dampers 15 and 16 is performed by a control device (not shown).

Each air supply flow path 7 is provided with an air volume adjusting damper 12 that controls the amount of air flow of the harmonized air whose humidity and temperature are controlled by the humidity control device 4. The air volume adjusting damper 12 is, for example, a butterfly valve type, and the opening degree is controlled by an actuator (not shown) such as a motor. The opening degree of each air volume adjusting damper 12 is controlled by a control device (not shown).

Moreover, the humidity of each indoor space S1, S2, S3 can be individually adjusted to a desired humidity for each space, and each indoor space S1, S2, S3 can be individually ventilated for each space.

Specifically, the humidity of each indoor space S1, S2, S3 is adjusted by controlling the temperature of the refrigerant coil 40 of the humidity control device 4, but the air volume adjusting damper 12 provided in each air supply flow path 7 is adjusted. The humidity of each indoor space S1, S2, S3 can also be adjusted by controlling the opening degree of the above and adjusting the air volume of the conditioned air supplied to each indoor space S1, S2, S3. Therefore, the control device controls each device based on the humidity and / or temperature of each indoor space S1, S2, S3 according to an instruction from a controller (not shown) provided in each indoor space S1, S2, S3. By doing so, the humidity of each indoor space S1, S2, S3 can be set to a desired humidity.

On the other hand, the electric dampers 15 and 16 of the branch flow paths 50 and 80 connected to the indoor space (for example, S1 and S3) to be ventilated are opened, and each tributary connected to the other indoor space (for example, S2) is opened. By closing the electric dampers 15 and 16 on the roads 50 and 80, the indoor spaces S1 and S3 can be ventilated by operating the fans 11A and 11B. At this time, by controlling the opening degree of the air volume adjusting damper 12 of the air supply flow path 7 connected to the indoor spaces S1 and S3, the indoor spaces S1 and S3 may be adjusted in humidity and temperature. , It is not necessary to adjust the temperature. Further, in the indoor space S2 that is not ventilated, the humidity and temperature can be quickly adjusted by opening the air volume adjusting damper 12 of the air supply flow path 7.

Further, in the air conditioning system 1 of any of the embodiments of FIGS. 1 and 2 described above, as shown in FIG. 3, the radiation panel 14 may be used in combination to air-condition the indoor space S. (Note that FIG. 3 has a radiation panel 14 in FIG. 1). The radiation panel 14 can be installed on any of the ceiling, wall, and floor of the indoor space S, but in FIG. 3, it is installed on the ceiling.
