Description

  The present invention relates to an air conditioner having a humidifying function for collecting moisture contained in outside air, transporting and releasing the moisture into a room, and humidifying the room.

  In particular, in winter, not only the outside air temperature decreases but also the humidity often decreases, and it dries outdoors. It is ideal to increase the humidity of the room by humidifying it because it is affected by the indoor environment. It only needs to be operated with a dedicated humidifier in the room, but it takes time and labor to replenish humidifying water (tap water) frequently.

  Therefore, there is a demand for a device that can reliably humidify the room without taking time and effort. For example, [Patent Document 1] discloses an air conditioner having a humidifying function in response to this demand. In the present invention, moisture contained in the outside air is adsorbed, and the moisture is transported into the room and released to humidify the room.

Specifically, a moisture absorbing member that is rotationally driven is provided in the outdoor unit, and this moisture absorbing member adsorbs moisture contained in the outside air. Thereafter, the moisture absorbing member is heated by the heating means to desorb the moisture adsorbed from the moisture absorbing member. Then, the humidified air conveying means mixes air with the moisture desorbed from the moisture absorbing member and conveys it to the indoor unit.
JP 2002-317981 A

  By the way, according to [Patent Document 1], a humidifying water unit including the moisture absorbing member is provided in an upper portion of a chamber that houses refrigeration cycle components such as a compressor and an outdoor heat exchanger. Although there is no description in particular in the specification about the support posture of the moisture absorbing member, it is provided horizontally in the drawing, and an adsorption fan constituting high-humidity air generating means is disposed below a part of the moisture absorbing member.

  Further, a part of the circulation path constituting the discharge part and a desorption fan are provided below the remaining part of the moisture absorption member, and a part of the circulation path and a heater are provided above the moisture absorption member via the moisture absorption member. It is done. Since the hygroscopic member is supported in the horizontal direction, the height of the hygroscopic member itself can be much smaller than that of the posture in which the hygroscopic member stands in the vertical direction.

However, since the adsorption fan, a part of the circulation path, and the desorption fan are arranged below the hygroscopic member and these components are juxtaposed so as to face the hygroscopic member, the diameter of the hygroscopic member inevitably increases, and the device Has led to an increase in size.
Further, since air is guided from the lower part of the hygroscopic member by passing upward, the air is circulated and guided from the upper part to the lower part, so that the circulation path configuration is complicated. In particular, the lower part of the moisture absorbing member is provided with moisture condensation means such as a heat exchanger for condensation, so even if the moisture absorbing member is horizontal, the height of the entire humidifier can be increased by providing the condensation means. Become big.

  The present invention has been made on the basis of the above circumstances, and the object of the present invention is to make the structure compact and efficiently collect a sufficient amount of moisture from the outside air to increase the amount of humidification in the room. It is intended to provide an air conditioner.

In order to satisfy the above object, the present invention provides an air conditioner comprising an indoor unit and an outdoor unit having a heat pump refrigeration cycle, wherein the outdoor unit includes a casing whose interior is vertically divided by a partition plate, and the casing. A refrigeration cycle chamber that houses a compressor, an outdoor heat exchanger, an outdoor fan that guides outside air to the outdoor heat exchanger, and a humidifier that is installed above the partition plate in the housing. A humidifying chamber,
The humidifier includes an adsorption ventilation passage for conducting outside air, an adsorption rotating body that adsorbs moisture from outside air that is partially driven in the adsorption ventilation passage and is driven to be guided to the adsorption ventilation passage, A part of the ventilation passage is provided in close contact with the remaining part of the adsorbing rotator to guide the high-temperature heat exchange air and release the moisture adsorbed on the adsorption rotator into the heat exchange air. And a humidification medium that conveys and releases the high-humidity content in the heat exchange air into the room provided downstream of the adsorption rotation body of the heat exchange air in the regeneration ventilation path. The adsorbing air passage and the regeneration air passage where the adsorbing rotating body is interposed are provided in the horizontal direction, and the adsorbing rotating body is supported in an obliquely inclined posture.

  According to the present invention, it is possible to provide an air conditioner that is compact in configuration, efficiently collects a sufficient amount of moisture, and increases the amount of humidification in the room.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 (A) and FIG. 1 (B) are schematic configuration diagrams of the air conditioner S, and have different humidification structures for the room.
Each air conditioner S is composed of an indoor unit Sa and an outdoor unit Sb. The indoor unit Sa is mounted at a height of the wall surface H of the living room M, and the outdoor unit Sb is disposed outdoors U. The indoor unit Sa and the outdoor unit Sb are connected to each other by a connecting member R in which refrigerant pipes and cables are combined into one.

  Each of the indoor units Sa includes an indoor heat exchanger (not shown) in the housing and an indoor blower arranged to face the indoor heat exchanger, and the housing is provided with a suction port and a blowout port. By driving the indoor blower, the air in the living room M is sucked into the housing through the suction port, and then blown out from the blowout port after passing through the indoor heat exchanger.

  The indoor unit Sa shown in FIG. 1 (A) further accommodates a humidifying section Ka. The humidifying unit Ka has a function of mixing high-humidity high-temperature air sent from a humidifying device K, which will be described later, with heat exchange air blown from a blow-out port and releasing it into the living room M. Or it has the function to change the dew condensation water sent from the humidifier K into heat exchange air instead of water vapor, and to discharge to the living room M.

  Although the indoor unit Sb shown in FIG. 1B does not include the humidifying unit Ka, the humidifier Kb is disposed on the floor surface of the living room M. The humidifier Kb has a function of releasing high-humidity high-temperature air sent from a humidifier K described later to the living room M. Or it has a function which changes the dew condensation water sent from the humidifier K into the living room M instead of water vapor.

  In any of the outdoor units Sb, the inside of the housing 1 is vertically partitioned by the partition plate 2. A refrigeration cycle chamber 3 is formed at the lower part of the partition plate 2, and a humidification chamber 4 is formed at the upper part. The refrigeration cycle chamber 3 accommodates a compressor 5, an outdoor heat exchanger 6, and an outdoor blower 7 facing the outdoor heat exchanger 6. A humidifier K is accommodated in the humidification chamber 4.

  The compressor 5 and the outdoor heat exchanger 6 in the refrigeration cycle chamber 3 communicate with the indoor heat exchanger of the indoor unit Sa through a refrigerant pipe that is the connecting member R. That is, the compressor 5, the outdoor heat exchanger 6, the indoor heat exchanger, a decompression device and a four-way switching valve (not shown), and the like are communicated with each other so as to constitute a heat pump refrigeration cycle via the refrigerant pipe.

  An outside air inlet 8 is provided in the side surface of the casing 1 adjacent to the outdoor heat exchanger 6, and an outside air outlet 9 is provided in the side surface of the casing 1 facing the outdoor blower 7. When the outdoor blower 7 is driven, the outside air sucked from the outside air inlet 8 flows to the outside air outlet 9 via the outdoor heat exchanger 6.

  A humidifying medium conveying path (humidifying medium conveying means) 10 extends from the humidifying device K in the humidifying chamber 4 to the outside of the housing 1. The humidifying medium transport path 10 shown in FIG. 1A is integrated with the connecting member R and connected to the humidifying section Ka in the indoor unit Sa. The humidification medium conveyance path 10 shown to FIG. 1 (B) is connected to the humidifier Kb arrange | positioned on the back room M floor surface along a connection member R part.

Next, the humidifier K provided in the humidification chamber 4 of the outdoor unit Sb will be described in detail.
FIG. 2 is a schematic longitudinal sectional view of a part of the outdoor unit Sb, and schematically shows a schematic configuration of the humidifying device K together.

  The humidifier K is provided with a suction ventilation path 12 and a regeneration ventilation path 13, both of which are ducts. The adsorption ventilation path 12 and the regeneration ventilation path 13 are in close contact with each other over the entire surface and are provided in the horizontal direction. That is, the regeneration ventilation path 13 is located on the lower side, and the adsorption ventilation path 12 is located on the upper side, both of which are straight.

  The suction ventilation path 12 includes a first outside air introduction portion 14 a provided on one side of the housing 1 and opening to the outdoor U. The other side portion has a first outside air deriving portion 14 b provided on the other side portion of the housing 1 and opening to the outdoor U. Accordingly, the first outside air introduction part 14a and the first outside air lead-out part 14b are in the positions of the straight ends and face each other.

  The regeneration ventilation path 13 is provided with a second outside air introduction part 15a on the lower side of the first outside air derivation part 14b in the adsorption ventilation path 12, and the first outside air introduction part 14a in the adsorption ventilation path 12 is provided. A second outside air outlet 15b is provided on the lower side. Therefore, the second outside air introduction part 15a and the second outside air lead-out part 15b are located at both ends in a straight shape and face each other.

  An adsorption blower 17 is arranged in the vicinity of the first outside air outlet 14b in the adsorption ventilation path 12. As the suction blower 17 is driven, outdoor air, which is outdoor air, is introduced into the suction ventilation passage 12 from the first outdoor air introduction portion 14a and then circulated, and then the outdoor air passes through the first outdoor air lead-out portion 14b. U can be derived.

  A regeneration fan 18 is disposed in the vicinity of the second outside air outlet 15 b in the regeneration ventilation path 13. Moreover, the air heating body 20 which is a heater is arrange | positioned in the site | part vicinity of the 2nd external air introduction part 15a. As the regeneration fan 18 is driven, outside air can be introduced into the regeneration ventilation path 13 from the second outside air introduction portion 15 a and guided to the air heating body 20.

  Then, the outside air is led out from the second outside air deriving unit 15b, and the humidifying medium conveyance path (humidifying medium conveying unit) 10 described above is connected to the second outside air deriving unit 15b. That is, the air derived from the second outside air deriving portion 15 b of the regeneration ventilation path 13 is directly guided to the humidifying medium transport path 10.

  An adsorption rotator 21 is interposed at a substantially central portion in the longitudinal direction of the suction ventilation path 12 and the regeneration ventilation path 13. A part of the suction rotating body 21 is interposed in the suction ventilation path 12, and the remaining part is interposed in the regeneration ventilation path 13. And the said adsorption | suction rotary body 21 is supported with the attitude | position inclined diagonally with respect to each ventilation path 12 and 13, and is connected with the rotation drive source which is not shown in figure.

The adsorption rotator 21 has, for example, a disk shape with a diameter of 20 to 30 cm and a thickness of about 2 to 3 cm, and is driven to rotate at a slow speed of 3 to 5 rpm. Further, the adsorption rotator 21 includes a large number of honeycomb-like air passages from one side surface to the other side surface, and a hygroscopic material such as zeolite is supported on the surfaces of these air passages with a uniform thickness.
The hygroscopic material has a characteristic of efficiently adsorbing moisture in the air in a low temperature environment and smoothly desorbing the adsorbed moisture in a high temperature environment.

  The formation direction of the honeycomb-like air passage of the adsorption rotator 21 coincides with the longitudinal direction of the adsorption ventilation passage 12 and the regeneration ventilation passage 13. Therefore, when there is ventilation in the suction ventilation path 12 and the regeneration ventilation path 13, this air flow smoothly flows through the air flow path of the adsorption rotating body 21. The adsorption rotator 21 may be entirely made of porous zeolite.

  In order to humidify the interior of the living room M by operating the humidifier K configured in this way in the winter season, a heating operation is performed as the air conditioner S. That is, the compressor 5 in the outdoor unit Sb is driven, and the heat pump operation is started. At the same time, the outdoor blower 7 and the indoor blower are driven, and the suction blower 17, the regeneration blower 18 and the suction rotating body 21 are driven to generate heat in the air heating body 20.

  The compressor 5 compresses the refrigerant and discharges it in a state of high temperature and pressure. The high-temperature and high-pressure refrigerant is guided to the indoor heat exchanger in the indoor unit Sa, where the refrigerant is condensed and releases condensation heat to the indoor air sucked from the suction port. The indoor blower blows high-temperature indoor air from the outlet to the living room M, and the indoor temperature rises. That is, the heating action for the living room M is performed.

  On the other hand, in the humidifier K, the outside air is introduced and circulated from the first outside air introduction portion 14a to the suction ventilation passage 12 by driving the suction fan 17. And outside air is guide | induced to a part of adsorption | suction rotation body 21, distribute | circulates a honeycomb-like air flow path, and the water | moisture content in outside air is adsorb | sucked and collected by the moisture absorption material carry | supported here.

  The outside air in which moisture is adsorbed and collected by the adsorption rotating body 21 is discharged to the outdoor U from the first outside air deriving unit 14b. Further, by driving the regeneration fan 18, outside air is introduced from the second outside air introduction portion 15 a into the regeneration ventilation path 13. Immediately thereafter, the outside air is heated by the air heater 20 and the temperature rises.

  The high temperature outside air is guided to the adsorption rotating body 21 and circulates. The adsorption rotator 21 is continuously rotating, and a portion where moisture is adsorbed and collected from the outside air guided to the adsorption ventilation path 12 faces the regeneration ventilation path 13 as time passes. Since the outside air guided to the regeneration ventilation path 13 is heated by the air heating body 20, the adsorption rotating body 21 is heated.

  Therefore, the collected moisture is desorbed from the hygroscopic material carried in the air flow passage of the adsorption rotating body 21. When high-temperature air flows out from the adsorption rotator 21, the high-temperature air contains sufficient moisture and changes to a high-humidity and high-temperature state. The high-humidity and high-temperature air is guided to the humidifying medium conveyance path 10 via the regeneration fan 18 and the second outside air outlet 15b.

  In the humidifier Ka or the humidifier Kb connected to the humidifying medium conveying path 10 described above with reference to FIGS. 1A and 1B, the high-humidity and high-temperature air guided from the humidifying medium conveying path 10 is directly placed in the living room. Guide into M. Therefore, the humidity in the living room M rises in a short time, preventing drying and improving comfort.

  Thus, the humidifier K adsorbs and collects moisture from the outside air, sends the air containing the moisture to the side of the room M, and releases it to perform a humidifying action in the room. Therefore, unlike the conventionally used humidifier, it is not necessary to supply water to the humidifying tank, and the humidifying device K that is easy to handle can be provided.

  The adsorption rotator 21 constituting the humidifying device K is provided to be inclined with respect to the longitudinal direction (horizontal direction) of the adsorption ventilation path 12 and the regeneration ventilation path 13. As a result, the adsorption rotating body 21 can secure a sufficient flow area for each of the ventilation passages 12 and 13 and can be made compact by keeping the height dimension as the humidifying device K low, thereby increasing the size of the outdoor unit Sb. Suppress.

  Further, since both the suction ventilation path 12 and the regeneration ventilation path 13 are formed in a straight shape, the outside air can be supplied to each ventilation path 12 by driving the suction blower 17 and the regeneration blower 18 disposed in each. , 13 are smoothly distributed. In other words, the simplification of the configuration of the suction ventilation path 12 and the regeneration ventilation path 13 can improve the blowing efficiency.

  In the above embodiment, the first outside air introduction portion 14a in the adsorption ventilation path 12 is provided at the upper part of the outside air intake port 8, and the blowing direction of the outside air by the outdoor blower 7 and the ventilation of the adsorption ventilation path 12 are provided. The direction is the same. On the other hand, in the ventilation path 13 for reproduction | regeneration, the 2nd outside air introduction part 15a is provided in the blowing side of the outdoor air blower 7 and the ventilation path 12 for adsorption | suction.

  As it is, there is a possibility that a short circuit phenomenon may occur in which the outside air blown from the outdoor blower 7 and the suction ventilation path 12 is sucked by the second outside air introduction portion 15a of the regeneration ventilation path 13. Moreover, the outside air blown out from the outdoor blower 7 and the suction ventilation path 12 is in a dry state, which affects the moisture absorption performance of the adsorption rotator 21 interposed in the regeneration ventilation path 13.

  Therefore, a hood is provided around the second outside air introduction portion 15a so that the second outside air introduction portion 15a of the regeneration ventilation passage 13 does not suck the outside air blown from the outdoor blower 7 and the suction ventilation passage 12. Alternatively, it is necessary to reliably prevent the short circuit phenomenon, for example, by providing the second outside air introduction portion 15a on the side surface of the housing 1 different from the surface on which the outside air outlet 9 and the first outside air outlet 14b are provided.

On the other hand, FIG. 3 is a schematic configuration diagram of a part of the outdoor unit that basically prevents the short circuit phenomenon from occurring.
The outside air inlet 8 and the outside air outlet 9 provided on the refrigeration cycle chamber 3 side are the same as the positions described above with reference to FIG. The positions of the first outside air introducing portion 14a and the first outside air deriving portion 14b of the suction ventilation path 12 are not changed. On the other hand, in the regeneration ventilation path 13, the second outside air introduction part 15 a is provided on the lower side of the first outside air introduction part 14 a in the adsorption ventilation path 12 and on the upper side of the outside air inlet 8.

  Further, the second outside air deriving portion 15 b in the regeneration ventilation path 13 is provided on the lower side of the first outside air deriving section 14 b in the adsorption ventilation path 12 and on the upper side of the outside air outlet 9. Accordingly, the second outside air introduction portion 15a and the second outside air derivation portion 15b of the regeneration ventilation path 13 are provided at positions opposite to the configuration described in FIG.

  In other words, the outside air inlet 8 that is an inlet of the outside air blown by the outdoor fan 7 to the outdoor heat exchanger 6, the first outside air introduction portion 14 a that is the inlet of the outside air to the suction ventilation path 12, and the regeneration The second outside air introduction portion 15 a that is an inlet of heat exchange air to the ventilation path 13 is provided on the same side surface portion of the outdoor unit housing 1.

  Therefore, in each ventilation path, fresh outside air is sucked in as intake air, and a short circuit phenomenon in which any exhaust is sucked into another ventilation path does not occur. For this reason, the dry air after heat exchange in the outdoor heat exchanger 6 and the dried air after moisture absorption from the adsorption ventilation path 12 are not guided to the regeneration ventilation path 13, and the moisture content is not contained in the regeneration ventilation path 13. It can inhale a lot of outside air and does not deteriorate the humidification performance.

  The air heater 20 may use not only a dedicated heater but also an inverter that drives a compressor that constitutes the electric circuit of the air conditioner S, or a reactor provided on the power source side of the inverter. . Furthermore, an auxiliary heat exchanger may be provided in the discharge side refrigerant pipe of the compressor 5 to guide the high-temperature refrigerant. In any case, the running cost can be reduced because the temperature rises with the action of itself.

  Furthermore, although the humidification device K in the above-described embodiment is configured with the suction ventilation path 12 at the top and the regeneration ventilation path 13 at the bottom, it is not limited to this. Even if the suction ventilation path 12 and the regeneration ventilation path 13 are provided upside down, the configuration of the humidifier K can be simplified, and the compactness is not hindered.

  In addition, the suction fan 17 of the suction air passage 12 can be omitted, and the outdoor fan 7 can also be used. That is, an opening which is the first outside air deriving portion 14b is provided on the suction side in the vicinity of the outdoor fan 7 of the partition plate 2. The first outside air outlet 14b may be provided with a damper that is closed when the humidifier K is stopped and opened during operation.

  Therefore, with the air blowing action of the outdoor blower 7, the suction air passage 12 becomes negative pressure through the opened first outside air outlet 14b, and the outside air is smoothly introduced into the suction air passage 12, Can be secured. When the humidifier k is stopped, the first outside air outlet 14b is closed with a damper to prevent dust from entering the humidifier K.

  Although high-humidity and high-temperature air is conveyed to the humidifying unit Ka or the humidifier Kb as the humidifying medium, the present invention is not limited to this. That is, after obtaining high-humidity and high-temperature air in the regeneration ventilation path 13, this air may be condensed to generate condensed water and conveyed to the living room M via the humidifying medium conveyance path 10.

  Also in this case, the suction ventilation path 12 and the regeneration ventilation path 13 can be configured to be compact as the humidifying device K by suppressing the overall height dimension. Further, it is not changed at all to support the suction rotator 21 in an inclined posture with respect to the ventilation paths 12 and 13, and it is needless to say that the same effect as that of the above embodiment is obtained.

  However, in this configuration, the humidifying unit Ka or the humidifier Kb requires a means for heating the condensed water that has been conveyed or using ultrasonic waves to change to water vapor. Further, it is more convenient if a means for forcibly diffusing the obtained water vapor into the living room M and reducing the humidity in a short time is provided.

  In other words, in order to condense high-humidity and high-temperature air to obtain condensed water, a heat exchanger for condensation is required, and the drain tank that receives the condensed water and the condensed water to the humidifier Ka / humidifier Kb. A pump for pumping water is also necessary, and it is inevitable that the cost will be affected. In other words, if it is the structure which conveys high-humidity high temperature air to the living room M as it is as mentioned above, it can provide more cheaply.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
