Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Fig. 1 to 3 show a preferred embodiment of the present invention.
The present embodiment provides an air conditioner 100, and the air conditioner 100 has a better dehumidification performance and is more suitable for being used in areas with higher humidity. As shown in fig. 3, the air conditioner 100 includes an indoor unit 110 and an outdoor unit 120, wherein the indoor unit 110 is installed in a first space 10, and the outdoor unit 120 is installed in a second space 20 isolated from the first space 10. If the air conditioner 100 is a common household air conditioner, the indoor unit 110 may be disposed in a room of a user, that is, the first space 10 is a space in the room of the user. The outdoor unit 120 may be disposed in an outdoor environment, that is, an outdoor environment space not communicating with a user room can be referred to as a second space 20.
The air conditioner 100 includes an indoor heat exchanger 111 disposed indoors (i.e., the first space 10, the same below) and a first outdoor heat exchanger 121 disposed outdoors (i.e., the second space 20, the same below). The indoor heat exchanger 111 is provided in the indoor unit 110, and the first outdoor heat exchanger 121 is provided in the outdoor unit 120. A desiccant 1232 is attached to the first outdoor heat exchanger 121, and the desiccant 1232 absorbs moisture in the air.
The air conditioner 100 further includes a dehumidification air guide duct 124, and the dehumidification air guide duct 124 is configured to guide the air in the first space 10 to the first outdoor heat exchanger 121 in the second space 20, and guide the air after being guided to the first outdoor heat exchanger 121 to the first space 10. After the air with high indoor humidity is guided to the first outdoor heat exchanger 121, moisture is absorbed by the desiccant to become dry air, and the dehumidified air is guided into the first space 10 through the dehumidification air guide duct to form a dehumidification cycle. In the process of the dehumidification cycle, moisture in the indoor air is continuously absorbed by the desiccant 1232 attached to the first outdoor heat exchanger 121, so that the purpose of dehumidifying the indoor air is achieved.
The desiccant 1232 may be made of any known material capable of adsorbing moisture in the air, and the adsorption process may be physical adsorption or chemical adsorption. The material of the drying agent 1232 may be a disposable adsorbing material (i.e. it can be adsorbed once and cannot be reused), or a repetitive adsorbing material. When the desiccant 1232 is a disposable adsorbent material, the dehumidification process of the air conditioner requires the user or maintenance personnel to periodically replace the saturated desiccant 1232. When the drying agent 1232 is a repeatedly adsorbing material, the drying agent 1232 can be heated to volatilize water after saturation of adsorption, so as to regenerate the adsorption capacity. In this embodiment, the adsorbent may be a repetitive adsorption material, and since the adsorbent is close to the first outdoor heat exchanger 121, the first outdoor heat exchanger 121 serves as a condenser in summer, and the temperature thereof is high in operation. The drying agent 1232 can absorb heat at any time to volatilize the moisture adsorbed by itself, so that the moisture is prevented from being saturated by adsorption, and the repeated utilization is realized.
The desiccant 1232 is disposed in the outdoor unit 120. Specifically, the desiccant 1232 may be disposed at the first outdoor heat exchanger 121, so that the desiccant 1232 can absorb heat of the first outdoor heat exchanger 121, and the desiccant 1232 can absorb heat to increase the evaporation rate of moisture thereon. In order to be able to sufficiently absorb the heat on the first outdoor heat exchanger 121, the desiccant 1232 may be attached to the fins of the first outdoor heat exchanger 121. In other embodiments, when the material of the drying agent 1232 is sensitive to temperature and cannot withstand too high temperature, the drying agent 1232 may be disposed near the first outdoor heat exchanger 121, so that the temperature of the first outdoor heat exchanger 121 cannot completely act on the drying agent 1232.
When the air conditioner 100 is in the cooling mode, if the indoor air is directly guided to the first outdoor heat exchanger 121, the temperature of the air circularly guided into the room is increased, and the cooling effect of the air conditioner is further affected. Although this drawback can be solved by increasing the operation power of the air conditioner, it still causes a certain energy loss. In order to solve the above-mentioned drawback, the air conditioner 100 may further include a second outdoor heat exchanger 122 and a first switching device.
The second outdoor heat exchanger 122 is provided in the outdoor unit 120, and a desiccant 1262 is also attached to the second outdoor heat exchanger 122. The desiccant 1262 attached to the second outdoor heat exchanger 122 and the desiccant 1232 attached to the first outdoor heat exchanger 121 may be made of the same material, and the arrangement positions of the two may be the same. The heat exchange pipeline of the second outdoor heat exchanger 122 may be in parallel communication with the heat exchange pipeline of the first outdoor heat exchanger 121, and the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 are both disposed at the downstream of the compressor 130 of the air conditioner 100 (with reference to the flowing direction of the refrigerant), that is, it can be understood that the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 can perform the same function, and in the air-conditioning cooling mode, if the second outdoor heat exchanger 122 works, it is in a heating state.
The first switching device is connected to a heat exchange line of the air conditioner 100, and has a first switching state and a second switching state. When the first switching device is in the first switching state, the refrigerant in the first outdoor heat exchanger 121 is turned on, and the refrigerant in the second outdoor heat exchanger 122 is turned off; when the first switching device is in the second switching state, the refrigerant in the second outdoor heat exchanger 122 is turned on, and the refrigerant in the first outdoor heat exchanger 121 is turned off. That is, when the first switching device is in the first switching state, it operates the first outdoor heat exchanger 121 and does not operate the second outdoor heat exchanger 122. When the first switching device is in the second switching state, it deactivates the first outdoor heat exchanger 121 and activates the second outdoor heat exchanger 122. In other words, the first switching device may shift the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122.
The first switching device may be two electrically controlled valves, wherein one valve controls the flow and stop of the refrigerant in the first outdoor heat exchanger 121, and the other valve controls the flow and stop of the refrigerant in the second outdoor heat exchanger 122. The two electrically controlled valves are controlled by a control circuit of the air conditioner 100. The control circuit can control the two valves to be opened simultaneously, the two heat exchangers work simultaneously at the moment, the control circuit can only open one of the valves, and only one of the heat exchangers works at the moment. In this embodiment, the control circuit controls the two valves to open and close alternately, so that the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 work alternately.
Also, when the air conditioner 100 has the second outdoor heat exchanger 122, the dehumidification air guide duct 124 is configured to guide the air in the first space 10 to the second outdoor heat exchanger 122 in the second space 20, and guide the air guided to the second outdoor heat exchanger 122 to the first space 10. That is, the air conditioner 100 may have two circulation ducts, and the air in one circulation duct undergoes the air circulation of "indoor-first outdoor heat exchanger 121-indoor" and the air in the other circulation duct undergoes the air circulation of "indoor-second outdoor heat exchanger 122-indoor". The dehumidifying air-guiding pipe 124 may only allow one of the circulating air ducts to be opened, or may allow two circulating air ducts to be opened simultaneously.
When the two circulation air ducts are opened simultaneously, the first switching device can control the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 to work in turns, so that the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 generate heat in turn, and only one of the two air flows in the two circulation air ducts has the temperature rising permanently, namely only a part of the air flowing into the room has the temperature rising. Compared with the structure with only one circulating air duct, the structure with two circulating air ducts can reduce the temperature rise of the air flowing into the room, and further reduce the energy loss of the air conditioner 100. Also, the first switching device may prevent the desiccant from being saturated by controlling the operation states of the first and second outdoor heat exchangers 121 and 122. For example, when the first switching device is in the first switching state, the second outdoor heat exchanger 122 does not operate, and the desiccant 1262 on the second outdoor heat exchanger 122 is prone to absorb moisture and saturate after dehumidification for a long time, at this time, the first switching device may be in the second switching state, and the second outdoor heat exchanger 122 may operate to generate heat (in a summer cooling mode), and after the desiccant absorbs heat generated by the second outdoor heat exchanger 122, moisture on the desiccant evaporates, so that dehumidification can be performed again.
When the two circulating air ducts are opened simultaneously, although the temperature rise of the air led back to the room can be reduced by about half (compared with the structure in which only one circulating air duct exists), the additional energy consumption of the air conditioner is increased. To further reduce the energy consumption of the air conditioner, in one embodiment, the air conditioner 100 may further include a second switching device.
The second switching device is connected to the dehumidification air guide duct 124 and configured to discharge the air guided to the first outdoor heat exchanger 121 out of the outdoor unit 120 when the first switching device is in the first switching state, and to discharge the air guided to the second outdoor heat exchanger 122 out of the outdoor unit 120 when the first switching device is in the second switching state. In other words, when the first outdoor heat exchanger 121 is operated and the second outdoor heat exchanger 122 is not operated, the second switching device controls the dehumidification air guide pipeline 124 to guide the indoor circulating air only to the second outdoor heat exchanger 122 (at this time, the second outdoor heat exchanger 122 does not generate heat), so that the desiccant 1262 on the second outdoor heat exchanger 122 dehumidifies the air, and the dehumidified air is introduced into the room again to form a dehumidification cycle. When the first outdoor heat exchanger 121 does not operate and the second outdoor heat exchanger 122 operates, the second switching device controls the dehumidification air guide pipeline 124 to guide indoor circulating air only to the first outdoor heat exchanger 121 (at this time, the first outdoor heat exchanger 121 does not generate heat), so that the desiccant 1232 on the first outdoor heat exchanger 121 dehumidifies the air, and the dehumidified air is introduced into the room again to form a dehumidification cycle. Therefore, after the second switching device is added, the air introduced into the outdoor unit 120 does not absorb the heat of the heat exchanger during the whole dehumidification cycle of the air conditioner 100, and the energy consumption of the air conditioner is reduced.
Meanwhile, when the second switching device is provided, the desiccant 1262 on the first outdoor heat exchanger 121 and the second outdoor heat exchanger 122 alternately dehumidify. When the first switching device is in the first switching state, the first outdoor heat exchanger 121 is operated and generates heat, the second outdoor heat exchanger 122 is not operated, and the indoor air is directed to the second outdoor heat exchanger 122 and dehumidified by the desiccant 1262 attached to the second outdoor heat exchanger 122. When the desiccant 1262 in the second outdoor heat exchanger 122 is saturated, the first switching device is switched to the second switching state, the second outdoor heat exchanger 122 operates and generates heat, and moisture in the desiccant 1262 attached to the second outdoor heat exchanger 122 is rapidly evaporated after absorbing heat, so that the dehumidification function is regained. In this way, the desiccant attached to the first outdoor heat exchanger 121 and the desiccant 1262 on the second outdoor heat exchanger 122 dehumidify in turn and evaporate moisture in turn, thereby avoiding the situation that the desiccant cannot continue to dehumidify after being saturated by moisture absorption.
The air conditioner 100 may further include a first hermetic case 123 and a second hermetic case 126. The first hermetic shell 123 defines a first hermetic chamber 1231 having a certain sealability, and the first outdoor heat exchanger 121 is disposed in the first hermetic chamber 1231. The second hermetic case 126 defines a second hermetic chamber 1261 having a certain sealability, and the second outdoor heat exchanger 122 is disposed in the second hermetic chamber 1261. The first sealing case 123 may guide all of the dehumidified air blown to the first outdoor heat exchanger 121 to the dehumidification air guide duct as much as possible and return the same to the room, and the second sealing case 126 may guide all of the dehumidified air blown to the second outdoor heat exchanger 122 to the dehumidification air guide duct as much as possible and return the same to the room, thereby preventing dry air from escaping and preventing relatively humid outdoor air from being introduced into the room.
When the first and second hermetic cases 123 and 126 are provided, the dehumidification air-guide duct 124 may include a first air inlet 1241, a first air outlet 1242, and a first air outlet 1243 in order to discharge moisture evaporated from the desiccant attached to the first outdoor heat exchanger 121 to the outside of the room and prevent the evaporated moisture from being discharged to the inside of the room. The first air inlet pipe 1241 is configured to introduce air in the first space 10 into the first sealed chamber 1231, the first air outlet pipe 1242 is configured to introduce air in the first sealed chamber 1231 into the first space 10, and the first air outlet pipe 1243 is configured to lead air in the first sealed chamber 1231 out of the outdoor unit 120. The dehumidifying air-guiding duct 124 may further include a second air inlet pipe 1244, a second air outlet pipe 1245 and a second air outlet pipe 1246. The second air inlet pipe 1244 is used to guide the air in the first space 10 into the second sealed chamber 1261, the second air outlet pipe 1245 is used to guide the air in the second sealed chamber 1261 into the first space 10, and the second air outlet pipe 1246 is used to guide the air in the second sealed chamber 1261 out of the outdoor unit 120.
The second switching device is configured to switch on the first air inlet pipe 1241, the first air outlet pipe 1243, the second air inlet pipe 1244 and the second air outlet pipe 1245 and switch off the first air outlet pipe 1242 and the second air outlet pipe 1246 when the first switching device is in the first switching state. When the moisture is evaporated in the desiccant 1232 attached to the first outdoor heat exchanger 121, the evaporated moisture is not discharged into the room, but is discharged out of the outdoor unit 120 through the first exhaust duct 1243. The air passing through the desiccant on the second heat exchanger is dehumidified and cannot be discharged to the outside, and is guided to the inside of the room by the second air outlet pipe 1245.
The second switching device is further configured to switch on the second air inlet pipe 1244, the second air outlet pipe 1246, the first air inlet pipe 1241 and the first air outlet pipe 1242 and switch off the second air outlet pipe 1245 and the first air outlet pipe 1243 when the first switching device is in the second switching state. When the moisture is evaporated in the drying agent 1262 attached to the second outdoor heat exchanger 122, the evaporated moisture is not discharged into the room, but is discharged out of the outdoor unit 120 through the second discharge duct 1246. The air passing through the desiccant on the first heat exchanger is dehumidified and cannot be discharged to the outside, and is guided to the inside of the room by the first air outlet pipe 1242.
In one embodiment, to increase the dehumidification efficiency, the temperature of the desiccant can be decreased when the desiccant dehumidifies, so as to increase the dehumidification efficiency of the desiccant (moisture in the air is more easily absorbed when the temperature is low, for example, when the temperature is lower than the dew point temperature, the common iron sheet can have the dehumidification effect). To enable the temperature of the desiccant (in the dehumidified state) to be reduced, the air conditioner 100 may further include a first cooling system 128 and a second cooling system 127. The first cooling system 128 includes a first cooling pipeline, in which a cooling medium, which may be tap water with a relatively low temperature, flows. The first cooling pipeline is disposed through the first sealed cavity 1231 and configured to cool the desiccant 1232 on the first outdoor heat exchanger 121. The first cooling pipeline penetrating through the first sealed cavity 1231 may be wound around the first outdoor heat exchanger 121 to sufficiently cool the desiccant (particularly, the desiccant in the dehumidification operation state) attached to the first outdoor heat exchanger 121, so as to accelerate the dehumidification efficiency of the desiccant attached to the first outdoor heat exchanger 121. The second cooling system 127 includes a second cooling pipeline, in which a cooling medium flows, and the cooling medium may specifically be tap water with a relatively low temperature. A second cooling line is disposed through the second sealed cavity 1261 and configured to cool the desiccant 1262 on the second outdoor heat exchanger 122. The second cooling pipeline penetrating through the second sealed cavity 1261 may be wound around the second outdoor heat exchanger 122 to sufficiently cool the desiccant (particularly, the desiccant in the dehumidification operation state) attached to the second outdoor heat exchanger 122, so as to accelerate the dehumidification efficiency of the desiccant attached to the second outdoor heat exchanger 122.
In order to allow the desiccant to be cooled in the dehumidification state and not in the regeneration state (where the desiccant is in a heated state to evaporate moisture), the air conditioner 100 may further include a third switching device. A third switching device is connected to the first cooling system 128 and the second cooling system 127, the third switching device being configured to turn off the cooling medium in the first cooling line and to turn on the cooling medium in the second cooling line when the first switching device is in the first switching state. At this time, the first cooling system 128 cannot cool the desiccant in the regeneration state on the first outdoor heat exchanger 121, and the second cooling system 127 cools the desiccant in the dehumidification state on the second outdoor heat exchanger 122. The third switching device is also configured to turn on the cooling medium in the first cooling line and turn off the cooling medium in the second cooling line when the first switching device is in the second switching state. At this time, the first cooling system 128 cools the desiccant in the dehumidification state on the first outdoor heat exchanger 121, and the second cooling system 127 cannot cool the desiccant in the regeneration state on the second outdoor heat exchanger 122.
In particular, the first cooling line may be connected in parallel with the second cooling line, such that the first cooling line and the cooling line share the cooling medium. The structure of the cooling system can be simplified, and the processing and manufacturing cost is saved. When the cooling medium in the cooling system is tap water, the outdoor unit 120 may be provided with a water inlet for introducing cooling water by connecting with a tap water pipe of a user.
The air conditioner 100 further includes an indoor heat exchanger 111 located indoors, and the dehumidification air guide duct 124 is configured to pass the air introduced into the first space 10 through the indoor heat exchanger 111. That is, the dehumidified air flows through the indoor heat exchanger 111, and the indoor heat exchanger 111 can cool the air introduced into the room, while the indoor heat exchanger 111 can further dehumidify the air introduced into the room.
The specific working flow of the air conditioner 100 in this embodiment is as follows:
as shown in fig. 1, in the initial state, for example, when the first switching device is in the first switching state. The first outdoor heat exchanger 121 operates and generates heat (in the cooling mode), and the second outdoor heat exchanger 122 does not operate. The second switching device guides a part of indoor air into the first sealed cavity 1231 and then out of the outdoor unit 120 through the first exhaust pipe 1243, and the air takes away moisture evaporated from the desiccant in the first sealed cavity 1231 in the process of being guided out of the outdoor unit 120. The second switching device also guides a part of the air in the room into the second sealed cavity 1261 and then into the indoor heat exchanger 111 through the second air outlet pipe 1245. The air is subjected to primary dehumidification by the desiccant in the second sealed chamber 1261, and then subjected to secondary dehumidification by the indoor heat exchanger 111. The indoor air undergoes an "indoor-to-second capsule 1261-indoor" dehumidification cycle. To increase the dehumidification efficiency of the desiccant in the second sealed chamber 1261, the third switching device cuts off the cooling medium in the first cooling pipeline to prevent the moisture increasing efficiency of the desiccant in the first sealed chamber 1231 from being reduced. The third switching device also conducts the cooling medium in the second cooling pipeline to cool the desiccant in the second sealed cavity 1261, so as to accelerate the dehumidification efficiency of the desiccant in the second sealed cavity 1261.
As shown in fig. 2, when the desiccant in the second sealed cavity 1261 is detected to be dehumidified and saturated, the first switching device is switched to the second switching state. The second outdoor heat exchanger 122 operates and generates heat (in the cooling mode), and the first outdoor heat exchanger 121 does not operate. The second switching device guides a portion of the indoor air into the second sealed chamber 1261 and then the air is guided out of the outdoor unit 120 through the second exhaust pipe 1246, and the air guides away the moisture evaporated from the desiccant in the second sealed chamber 1261 in the process of being guided out of the outdoor unit 120. The second switching device also guides a part of the air in the room into the first sealed chamber 1231 and then into the indoor heat exchanger 111 through the first air outlet pipe 1242. The air is subjected to primary dehumidification by the desiccant in the first sealed chamber 1231, and then subjected to secondary dehumidification by the indoor heat exchanger 111. The indoor air performs an indoor-first sealed chamber 1231-indoor dehumidification cycle. In order to increase the dehumidification efficiency of the desiccant in the first sealed chamber 1231, the third switching device stops the cooling medium in the second cooling line to prevent the moisture increase efficiency of the desiccant in the second sealed chamber 1261 from being reduced. The third switching device further enables the cooling medium in the first cooling pipeline to be conducted so as to cool the desiccant in the first sealed cavity 1231, thereby accelerating the dehumidification efficiency of the desiccant in the first sealed cavity 1231.
Thus, it should be appreciated by those skilled in the art that while various exemplary embodiments of the invention have been shown and described in detail herein, many other variations or modifications which are consistent with the principles of this invention may be determined or derived directly from the disclosure of the present invention without departing from the spirit and scope of the invention.
