BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for dry dehumidification and ventilation that does not require water supply or drain water treatment, and for preventing dew condensation on walls.

0002

2. Description of the Related Art A conventional dry dehumidification/humidification device is disclosed in, for example, Japanese Patent Laid-Open No. 63-286634. As shown in FIG. 2, this device is composed of an air path switching section 5, an adsorbent 1 and a heater 2, a blower 3, and an air path switching section 4 in order from the top. It is now possible to switch the air path.

[0003] When humidifying with the above configuration, the air path switching section 4 is set to open to the outside of the room and allow outdoor air to pass through the adsorbent material 1, and then return to the outside through the air path switching section 5. Moisture in the outdoor air is adsorbed by the adsorbent 1. Thereafter, the air path switching units 4 and 5 close the air path on the outdoor side, and after the indoor air passes through the adsorbent 1, it is set so that it returns to the indoor room again. At this time, the indoor air is heated by heater 2,
When passing through the adsorbent 1, the adsorbent 1 is heated to remove the adsorbed moisture, and this moisture is supplied into the room, thereby performing dry humidification.

0004

[Problems to be Solved by the Invention] In the configuration of such a conventional dry dehumidification device, (1) during regeneration, the air temperature supplied to the adsorbent material 1 is higher than the temperature during adsorption operation; Thermal swing absorption, which is a method of desorbing moisture adsorbed by the adsorbent 1, is used, but heat exchange loss occurs when the temperature of the regeneration air is raised by the heater 2, and hot air passes through the air path. There are heat radiation losses when the adsorbent 1 is heated, heat losses when the hot air heats the adsorbent 1, and the like. As a result, it consumes a lot of energy and has a high running cost (nearly 10 times higher than the ultrasonic method) compared to other humidification methods, making it uncompetitive in price. Furthermore, since the adsorbent 1 is heated indirectly, the regeneration time becomes long, and therefore, since the adsorption operation and the regeneration operation are performed alternately, the humidification ability is affected by the regeneration time, and the ability cannot be fully demonstrated. In order to guarantee the capacity, it was necessary to increase the amount of adsorbent 1.

(2) In winter, walls such as windows are in direct contact with the outdoors, so in order to prevent condensation on these parts, it is necessary to lower the absolute humidity indoors to 5 to 6 (g/Kg). Under these conditions, the problem was that the room became too dry.

The present invention solves these conventional problems and is a dry dehumidification/humidification device that consumes less power, can control air components other than moisture, and further prevents indoor dew condensation.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides an adsorption section consisting of an adsorption material and a heating source incorporated in the adsorption material, a blower for sending air to the adsorption section, A plurality of air supply ports are provided on the upstream side of the suction section, and a plurality of exhaust ports are provided on the downstream side of the suction section. Furthermore, the air supply port is provided with a switching section for selecting an air path between the indoor side and the outdoor side, and the exhaust port is provided with a switching section for selecting the air path between the indoor side and the outdoor side. A bypass port facing into the room and a bypass switching section are provided in the air path connecting the opening and the switching section, and the suction section, the blower, the switching section,
a control section that controls a bypass switching section; A regeneration operation instruction to send the outdoor air through the adsorbent to desorb the moisture adsorbed in the adsorbent and exhaust it to the outside, and a regeneration operation instruction to send the air sucked from outside through the adsorbent to remove the moisture in the air. The humidifying operation includes an adsorption operation instruction to adsorb moisture and exhaust it to the outside, and a regeneration operation instruction to send indoor air to the adsorbent, desorb the moisture adsorbed by the adsorption material, and supply air into the room. When an adsorption operation was instructed, the dry air was exhausted to the outside, the bypass switching section was opened, and a bypass port was provided to supply a portion of the exhaust air to the wall surface of the room.

[0008]

[Function] With the above-described configuration, the air sucked from outside becomes dry air by adsorbing moisture to the adsorbent, and a portion of the dry air is supplied to the wall surface of the room from the bypass port. is in a dry state, and furthermore, the dry air becomes warm air due to adsorption heat and warms the wall surface, so no dew condensation occurs even under conditions where the wall surface is easily cooled (in winter). Moreover, since the dry air flowing over the wall is part of the exhaust air, it does not dry out the room.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0010] In FIG. 1, 1A is an adsorption part, and a heat source 2
The adsorbent 1 is supported on the holder and formed into a corrugated shape. Reference numeral 3 denotes a blower, which is disposed upstream of the adsorption section 1A. 4 is a charged filter, which is provided upstream of the blower 3. 5 is an outdoor air supply port that takes in outdoor air; 6 is an outdoor exhaust port that exhausts air outdoors;
The outdoor exhaust port 6 is a double pipe. 7 is an indoor air supply port, and 8 is an indoor exhaust port. Reference numeral 9 denotes an air supply switching unit for selecting whether air is supplied from the indoor side or the outdoor side. Reference numeral 10 denotes an exhaust switching unit, which selects whether the exhaust is to be directed to the indoor side or the outdoor side. 11 is ON-OFF control of the heating heat source 2;
This is a control unit that controls the operation of the blower 3 and the switching units 9 and 10. Reference numeral 12 denotes a bypass port that sends air to the window glass portion 14 on the indoor side, and reference numeral 13 designates a bypass switching unit that is provided in an air path that supplies exhaust gas to the outside and supplies air to the bypass port 12.

Based on the above configuration, indoor humidification and prevention of dew condensation will be explained. During humidification (in winter in most cases), the control unit 11 instructs to start with the suction operation. (The adsorbent 1 has moisture adsorbed by diffusion, but in order to adsorb it to near the saturated adsorption amount, it first starts with an adsorption operation. Therefore, the first adsorption operation time is shorter than the subsequent adsorption operation times. ) The air supply port switching section 9 and the exhaust switching section 10 close the indoor side, and the bypass switching section 13 is provided at a position to open the air path so that air flows from the bypass port 12. . The blower 3 starts operating and supplies outdoor air to the adsorbent 1 to adsorb moisture. Dry outdoor air is exhausted from the outdoor exhaust port 6, and part of it is supplied to the window glass from the bypass port 12, thereby drying the area around the window and preventing dew condensation. When the adsorbent 1 reaches the breakthrough state, the control section 11 stops the operation of the blower 3, and causes the air supply switching section 9 and the exhaust switching section 10 to close the outdoor side. Thereafter, the control unit 11 energizes the heating source 2 to heat the adsorbent 1. Indoor air passes through the adsorbent 1, which has reached the regeneration temperature and begins to desorb moisture, receives moisture and is supplied into the room. Humidification is achieved by repeating the above adsorption operation and regeneration operation. At this time, since the outdoor side of the exhaust switching section 10 is closed, air is not supplied from the bypass port 12.

Next, dehumidification will be explained. During dehumidification, the control unit 11 instructs to start from the regeneration operation. (Because adsorbent 1 has moisture adsorbed by diffusion)
The air supply port switching section 9 and the exhaust switching section 10 close the outdoor side. The blower 3 starts operating and supplies indoor air to the adsorbent 1 to adsorb moisture. Dry indoor air is exhausted from the indoor exhaust port 8. When the adsorbent 1 reaches the breakthrough state, the control section 11 stops the operation of the blower 3, and the air supply switching section 9 and the exhaust switching section 10 close the indoor side. Thereafter, the control unit 11 energizes the heating source 2 to heat the adsorbent 1. Outdoor air passes through the adsorbent 1, which has reached the regeneration temperature and begins to desorb moisture, receives moisture and is exhausted outside the room. By repeating the above adsorption operation and regeneration operation, dehumidification is achieved.

[0013] By selecting the dehumidification/humidification by detecting the indoor temperature/humidity and air component concentration, an optimal indoor environment can be maintained at all times.

[0014]

[Effects of the Invention] As described above, according to the dry dehumidification/humidification device of the present invention, the following effects can be obtained.

(1) Since the regeneration operation directly heats the adsorbent, there is less heat loss and energy-saving operation can be achieved compared to the indirect heating method using hot air. Furthermore, since the response characteristics of the regeneration operation are improved, the dehumidification and humidification capabilities are also increased.

(2) By supplying a portion of the dry air during humidification operation to the wall surface, dew condensation on the wall surface can be prevented.

(3) When dehumidifying and humidifying, the adsorbent is heated, and this heat can sterilize bacteria and the like that flow into the device.

(4) By starting from the optimal operation for dehumidification and humidification, the dehumidification and humidification capabilities can be further enhanced.
