The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.
Next, an air conditioner 100 according to an embodiment of the present invention is described.
As shown in fig. 1, an air conditioner 100 according to an embodiment of the present invention may include a compressor system 3 and a liquid pumping system 4.
As shown in fig. 1, the compressor system 3 may include in circulation communication: a first heat exchanger 31, a second heat exchanger 32, a compressor 33 and a throttling element 34, a refrigerant 3a circulating in the compressor system 3. The compressor system 3 may be a single cooling system 3a (as shown in fig. 1) or a heat pump system 3b (as shown in fig. 2). Referring to fig. 2, when the compressor system 3 is a heat pump system 3b, the compressor system 3 may further include a four-way valve 35. The concepts, other configurations and operating principles of "single-cooling systems" and "heat pump systems" are well known to those skilled in the art.
The following is only an example of the compressor system 3 as the single cooling system 3a, and the composition and operation of the compressor system 3 will be briefly described, and it will be apparent to those skilled in the art after reading the following technical solutions that the composition and operation of the compressor system 3 as the heat pump system 3b can be understood. As shown in fig. 1, when the compressor system 3 is a single cooling system 3a, the outlet of the compressor 33 is communicated with the inlet of the first heat exchanger 31, the outlet of the first heat exchanger 31 is communicated with the inlet of the throttling element 34, the outlet of the throttling element 34 is communicated with the inlet of the second heat exchanger 32, and the outlet of the second heat exchanger 32 is communicated with the inlet of the compressor 33, at this time, the first heat exchanger 31 realizes heat release for the condenser to exchange heat with the environment, and the second heat exchanger 32 realizes heat absorption (i.e., heat release) for the evaporator to exchange heat with the environment. When the single cooling system 3a is in operation, the refrigerant 3a in the compressor system 3 circulates through the compressor 33, the first heat exchanger 31 (i.e., a condenser), the throttling element 34, and the second heat exchanger 32 (i.e., an evaporator) in this order to realize a refrigeration cycle.
As shown in fig. 1, the liquid pumping system 4 may include in circulation communication: the third heat exchanger 41, the energy storage device 42 and the liquid pump device 43, the coolant 4b circulates in the liquid pump system 4, that is, the liquid pump device 43 is connected between the third heat exchanger 41 and the energy storage device 42, the liquid pump device 43 circulates the coolant 4b between the third heat exchanger 41 and the energy storage device 42, or the liquid pump device 43, the third heat exchanger 41 and the energy storage device 42 form a circulation loop, when the liquid pump device 43 works, the coolant 4b in the third heat exchanger 41 can flow to the energy storage device 42, and the coolant 4b in the energy storage device 42 flows back to the third heat exchanger 41 again to circulate.
As shown in fig. 1, the energy storage device 42 further includes an energy storage medium 4a that takes energy from the second heat exchanger 32 and stores energy, that is, when the compressor system 3 is a single-cold system 3a or a heat pump system 3b and performs a cooling mode, the second heat exchanger 32 releases cooling energy to the energy storage medium 4a, and the energy storage medium 4a absorbs cooling energy from the second heat exchanger 32 and stores cooling energy; when the compressor system 3 is the heat pump system 3b and the heating mode is performed, the second heat exchanger 32 releases heat to the energy storage medium 4a, and the energy storage medium 4a absorbs heat from the second heat exchanger 32 and stores the heat.
As shown in fig. 1, the coolant 4b exchanges heat with the energy storage medium 4a, that is, the energy (i.e., heat or cold) obtained and stored by the energy storage medium 4a from the second heat exchanger 32 can be exchanged to the coolant 4b and carried by the coolant 4b, so that when the liquid pumping system 4 operates, the coolant 4b can transfer the energy in the energy storage medium 4a and release the energy to the environment through the third heat exchanger 41, thereby changing the ambient temperature. For example, when the cold energy is stored in the energy storage medium 4a, the coolant 4b absorbs the cold energy from the energy storage medium 4a and transfers the cold energy to be discharged to the environment through the third heat exchanger 41, thereby reducing the temperature of the environment. For another example, when heat is stored in the energy storage medium 4a, the coolant 4b absorbs heat from the energy storage medium 4a and transfers the heat to be discharged to the environment through the third heat exchanger 41, thereby increasing the temperature of the environment.
Therefore, according to the air conditioner 100 of the embodiment of the present invention, in the process that the liquid pumping system 4 sends cold to the environment through the third heat exchanger 41, the coolant 4b exchanges heat with the energy storage medium 4a to release heat to the energy storage medium 4a, so that the liquid pumping system 4 does not discharge heat to the environment, and the air conditioner 100 can omit an exhaust duct for exhausting hot air, and the installation position of the air conditioner is not limited and can be moved freely.
In some embodiments of the present invention, the compressor system 3 of the air conditioner 100 can make ice from the energy storage medium 4a, similar to the refrigeration system of the refrigerator, and the liquid pumping system 4 can replace the refrigeration system of the mobile air conditioner in the related art, and can utilize the energy storage medium 4a to cool and accumulate the cold from the second heat exchanger 32 of the compressor system 3 and release the cold to the environment through the secondary refrigerant 4b and the third heat exchanger 41, thereby reducing the ambient temperature. Thus, in the working process of the liquid pump system 4, the heat exchanged between the secondary refrigerant 4b and the energy storage medium 4a is released to the energy storage medium 4a, so that the liquid pump system 4 can omit an exhaust pipe and the like for exhausting hot air, and further the air conditioner 100 can be moved freely, and the use scene is wide and is not limited, compared with a refrigeration system in a mobile air conditioner in the related art.
Furthermore, in some embodiments of the present invention, due to the liquid pumping system 4 with the energy storage medium 4a, the compressor system 3 and the liquid pumping system 4 may also not be operated simultaneously, for example, the compressor system 3 may be operated first, so that the energy storage device 42 stores energy from the second heat exchanger 32, and then the compressor system 3 may be shut down to reduce energy consumption and reduce noise. Thereafter, when the ambient temperature needs to be adjusted, the liquid pump system 4 may be turned on to use the energy stored by the energy storage device 42 to cause the third heat exchanger 41 to exchange heat with the environment, thereby adjusting the ambient temperature.
In addition, when the liquid pumping system 4 is used to reduce the ambient temperature, the coolant 4b in the liquid pumping system 4 exchanges cold with the environment on the one hand and exchanges heat with the energy storage medium 4a on the other hand, so that the coolant 4b does not discharge heat to the environment in a centralized manner, and in the working process of the liquid pumping system 4, the compressor system 3 may not work, so that the compressor system 3 may not discharge heat to the environment. Therefore, when the ambient temperature of the air conditioner 100 is reduced, the air conditioner 100 can discharge the ambient temperature without heat, so that the reliability of the liquid pump system 4 for reducing the ambient temperature can be ensured, and the air conditioner 100 can also omit an exhaust pipe for discharging hot air, so that the air conditioner 100 can be placed at any position, can also be moved freely when the air conditioner 100 is a mobile air conditioner, and has wide use scenes and no limitation. Of course, the present invention is not limited thereto, and the air conditioner 100 is not limited to a mobile air conditioner.
Next, an energy storage device 42 according to some embodiments of the invention is described.
Specifically, the energy storage device 42 according to the embodiment of the present invention may be various, and the energy storage device 42 according to the embodiment of the present invention will be described below by taking two specific embodiments as examples, but the energy storage device 42 according to the embodiment of the present invention is not limited to the following two embodiments.
Example one
In the first embodiment, as shown in fig. 1, the energy storage device 42 may include: the energy storage device comprises a tank 421 and a fourth heat exchanger 422, wherein an energy storage medium 4a is arranged in the tank 421, the second heat exchanger 32 is arranged in the energy storage medium 4a, the energy storage medium 4a can take energy from the second heat exchanger 32 and store the energy, the fourth heat exchanger 422 is arranged in the energy storage medium 4a to take energy from the energy storage medium 4a, and a liquid pump device 43 is connected between the third heat exchanger 41 and the fourth heat exchanger 422 so as to enable secondary refrigerant 4b to circulate between the third heat exchanger 41 and the fourth heat exchanger 422.
Specifically, when the compressor system 3 is in operation, the second heat exchanger 32 may release heat or cold to the energy storage medium 4a in the tank 421, so as to change the temperature of the energy storage medium 4a and store energy, and then the compressor system 3 may be turned off, so as to save electric energy, reduce noise, and the like. Thereafter, the liquid pumping device 43 can be opened to operate the liquid pumping system 4, at this time, the coolant 4b in the fourth heat exchanger 422 absorbs energy from the energy storage medium 4a and is delivered to the third heat exchanger 41 under the action of the liquid pumping device 43, so that the third heat exchanger 41 exchanges heat with the environment (i.e., is cooled or releases heat), the coolant 4b after exchanging heat in the third heat exchanger 41 is delivered back to the fourth heat exchanger 422 under the action of the liquid pumping device 43, energy is continuously taken from the energy storage medium 4a, and the circulation is repeated, so that the energy in the energy storage medium 4a can be gradually taken out and released to the environment, thereby adjusting the ambient temperature.
It should be noted that, in the first embodiment, the specific type of the energy storage medium 4a is not limited, for example, water may be used, and in the process of the compressor system 3 making the energy storage medium 4a store cold, the water may be frozen to better store cold, and the cost is low, and the cold storage and cold extraction effects are good, and in the first embodiment, the specific type of the coolant 4b circulating in the liquid pump system 4 is also not limited, for example, alcohol solution, such as methanol, ethylene glycol, glycerol, or low carbon alcohol hydrate, and thus the cold extraction and cold extraction effects may be improved. However, the energy storage medium 4a and the coolant 4b are not limited to the specific ones, as long as the freezing point of the coolant 4b is lower than the cold storage temperature of the energy storage medium 4a, and the coolant 4b can circulate without freezing. In addition, when the liquid pump device 43 is used to increase the ambient temperature, the materials of the energy storage medium 4a and the coolant 4b may be specifically selected according to actual requirements, and are not limited herein.
Example two
In the second embodiment, as shown in fig. 2, the energy storage device 42 may not include the fourth heat exchanger 422, and the second heat exchanger 32 may not be disposed in the tank 421. At this time, the energy storage device 42 may include a pipe 423, the coolant 4b circulates in the pipe 423, the pipe 423 may be disposed inside or outside the tank 421 to exchange heat with the energy storage medium 4a, and the second heat exchanger 32 is disposed outside the tank 421 and near or in contact with the tank 421 to exchange heat with the energy storage medium 4 a. Thus, the normal operation of the liquid pump system 4 can be realized, and the details are not described here.
In the following, for the sake of simplifying the description, only the liquid pumping system 4 is used to reduce the ambient temperature for example, and it is obvious that the technical solution when the liquid pumping system 4 is used to increase the ambient temperature can be understood by those skilled in the art after reading the following technical solution.
Next, a fluid pumping device 43 according to some embodiments of the present invention is described.
In some embodiments, as shown in fig. 1 and 2, the liquid pumping device 43 includes a first pump body 431, a first piping assembly 432, and a second piping assembly 433, the first pump body 431 being connected to the third heat exchanger 41 through the first piping assembly 432, and the first pump body 431 being connected to the energy storage device 42 through the second piping assembly 433. That is, refrigerant may flow between the first pump body 431 and the third heat exchanger 41 through the first pipe assembly 432, and refrigerant may flow between the first pump body 431 and the accumulator 42 through the second pipe assembly 432.
In some embodiments, at least one of the first tubing assembly 432 and the second tubing assembly 433 includes a flexible tube 430. That is, first conduit assembly 432 may include flexible tube 430, second conduit assembly 433 may also include flexible tube 430, and first conduit assembly 432 and second conduit assembly 433 may also each include flexible tube 430.
When the first pipeline assembly 432 comprises the flexible pipe 430, at least a part of the connection between the first pump body 431 and the third heat exchanger 41 is flexible, so that the relative position relationship between the first pump body 431 and the third heat exchanger 41 can be adjusted as required, and the assembly is convenient.

In the following, some specific embodiments of the air conditioner 100 according to the invention are described with respect to the structural arrangement.
As shown in fig. 5, the air conditioner 100 according to the embodiment of the present invention further includes a cabinet 1, and the compressor system 3 and the liquid pumping system 4 are both disposed in the cabinet 1 (in conjunction with fig. 1 and 2) to be protected by the cabinet 1, and make the air conditioner 100 an integral module for easy movement, transportation, installation and use.
Referring to fig. 14, in some embodiments, the casing 1 may have a first air duct 13a therein, and the air conditioner 100 may further include a first ventilation device 2a, the third heat exchanger 41 is disposed in the first air duct 13a, and the first ventilation device 2a ventilates the first air duct 13 a. Thereby, the speed at which the third heat exchanger 41 exchanges heat with the environment can be increased, thereby quickly adjusting the ambient temperature.
Referring to fig. 14, each of the air conditioners 100 may further include: and an electric storage device 8 (see fig. 14), the electric storage device 8 being electrically connected to at least the liquid pumping device 43 and the first ventilation device 2a to supply electric power to the liquid pumping device 43 and the first ventilation device 2 a. Therefore, the air conditioner 100 can be used as a mobile air conditioner, and after the compressor system 3 finishes operating, the power supply can be cut off, for example, the power storage device 8 is used for supplying power to the liquid pump device 43 and the first ventilation device 2a, so that the moving range of the air conditioner 100 is not limited, and the using range of the air conditioner 100 is widened.
Referring to fig. 14, in some embodiments, a second air duct 13b may be further disposed in the casing 1, and the air conditioner 100 may further include a second air ventilation device 2b, wherein the first heat exchanger 31 is disposed in the second air duct 13b, and the second air ventilation device 2b ventilates the second air duct 13 b. Thereby, the speed at which the first heat exchanger 31 exchanges heat with the environment can be increased, so that the energy storage medium 4a can be rapidly stored.
Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the first ventilation device 2a and the second ventilation device 2b may not be provided, and the heat exchange may be realized by natural wind. The specific selection of the electricity storage device 8 is not limited, and may be, for example, a battery or a storage battery.
In some specific examples, as shown in fig. 14, the first air duct 13a and the second air duct 13b may be different air ducts, and the first ventilation device 2a and the second ventilation device 2b may be different ventilation devices. That is, the first air duct 13a and the second air duct 13b are independent of each other, the first ventilation device 2a and the second ventilation device 2b are independent of each other, and the air flows in the first air duct 13a and the second air duct 13b do not affect each other. At this time, the compressor system 3 and the liquid pump system 4 can also work simultaneously without interfering with each other.
In other specific examples, as shown in fig. 8, the first air duct 13a and the second air duct 13b may be the same air duct 13, and the first ventilation device 2a and the second ventilation device 2b may be the same ventilation device 2. That is, the first heat exchanger 31 and the third heat exchanger 41 share the same air duct 13 and share the same ventilator 2. Therefore, the structure of the whole machine can be simplified, and at the moment, the compressor system 3 and the liquid pump system 4 can not work simultaneously.
In the following, only the first heat exchanger 31 and the third heat exchanger 41 share the same air duct 13 and share the same ventilator 2 are taken as an example for explanation, and it is obvious to those skilled in the art after reading the following technical solutions that the first heat exchanger 31 and the third heat exchanger 41 do not share the same air duct and do not share the same ventilator.
As shown in fig. 8, when the first air duct and the second air duct are the same air duct 13 and the first ventilator 2a and the second ventilator 2b are the same ventilator 2, the third heat exchanger 41 may be located downstream (front side as shown in fig. 8) of the first heat exchanger 31 in the air flow direction of the air duct 13 (from the rear to the front as shown in fig. 8), and the ventilator 2 may be located downstream (front side as shown in fig. 8) of the third heat exchanger 41. Therefore, the working effects of the third heat exchanger 41, the first heat exchanger 31, and the ventilation device 2 can be improved, and specific analysis is as follows.
In some embodiments, as shown in fig. 5 and 6, the casing 1 may include an air inlet 121 and an air outlet 111, and in conjunction with fig. 7 and 8, the casing 1 further has an air duct 13 communicating the air inlet 121 and the air outlet 111, and the first heat exchanger 31 and the third heat exchanger 41 are both disposed in the air duct 13. Referring to fig. 7 and 8, the air conditioner 100 may further include a ventilation device 2 for circulating the air flow in the air duct 13, and the ventilation device 2 is disposed in the casing 1 for allowing the air duct 13 to suck the air flow from the air inlet 121 and send the air flow from the air outlet 111. That is, when the ventilation device 2 operates, the airflow may enter the air duct 13 through the air inlet 121, exchange heat with the first heat exchanger 31 and the third heat exchanger 41 in the air duct 13, and then be sent out from the air outlet 111.
As described above, according to the air conditioner 100 of the embodiment of the present invention, the compressor system 3 and the liquid pump system 4 may be configured to not operate simultaneously, and therefore, when the compressor system 3 operates, the air flow entering the air duct 13 may exchange heat with the first heat exchanger 31 in operation, thereby achieving rapid heat release of the first heat exchanger 31, and when the liquid pump system 4 operates, the air flow entering the air duct 13 may exchange heat with the third heat exchanger 41 in operation, thereby achieving rapid heat release of the third heat exchanger 41.
Therefore, the first heat exchanger 31 and the third heat exchanger 41 are both arranged in the same air duct 13, and the air conditioner 100 can be constructed such that the compressor system 3 and the liquid pump system 4 do not work at the same time (i.e. the compressor system 3 can be operated to store energy first, and then the liquid pump system 4 is operated to cool down), so that the first heat exchanger 31 and the third heat exchanger 41 can share one set of ventilation device 2, thereby reducing the complexity of the whole air conditioner 100, and enabling the air conditioner 100 to be compact, small and low in cost.
In addition, it should be noted that, when the compressor system 3 or the liquid pump system 4 is in operation, the ventilation device 2 may not be operated, and at this time, heat exchange may be achieved by using external natural wind or an external blowing device, thereby reducing energy consumption. Therefore, the air conditioner 100 according to the embodiment of the present invention may not include a ventilation device. In addition, when the power consumption of the ventilation device 2 and the liquid pump device 43 is low, the air conditioner 100 may further include a battery, so that when the air conditioner 100 only works by using the liquid pump system 4, there is no need to connect a power line, that is, after the compressor system 3 finishes working, the air conditioner 100 may be separated from the difference mode, so that the air conditioner 100 may be moved at any time, the movable range of the mobile air conditioner is increased, and the requirements of different application scenarios are met.
In some embodiments, as shown in fig. 8, the third heat exchanger 41 may be disposed on a side of the first heat exchanger 31 close to the air outlet 111, that is, the third heat exchanger 41 is disposed between the first heat exchanger 31 and the air outlet 111. Therefore, the third heat exchanger 41 can be ensured to be closer to the air outlet 111, and when the liquid pump system 4 works, the cooling effect of the third heat exchanger 41 can be improved, and the ambient temperature can be better reduced.
In some embodiments, as shown in fig. 8, the ventilation device 2 may be disposed on a side of the third heat exchanger 41 close to the air outlet 111, that is, the ventilation device 2 is disposed between the third heat exchanger 41 and the air outlet 111. From this, can guarantee that ventilation unit 2 is nearer with the distance between air outlet 111, at ventilation unit 2 during operation, can reduce ventilation unit 2's windage, guarantee that ventilation unit 2's air volume meets the demands.
In some embodiments, as shown in FIG. 8, the first heat exchanger 31 may be disposed on a side of the third heat exchanger 41 near the air intake 121, that is, the first heat exchanger 31 is disposed between the third heat exchanger 41 and the air intake 121. Therefore, the first heat exchanger 31 can be ensured to be closer to the air inlet 121, and the heat releasing device 31 arranged close to the air inlet 121 can release heat better through the air inlet 121 on the premise that the air conditioner 100 does not have the ventilation device 2 or the ventilation device 2 does not work, so that the working reliability of the compressor system 3 is improved.
In some embodiments, as shown in fig. 7, the cabinet 1 may have an upper receiving space 14 and a lower receiving space 15 therein, at least one of the first heat exchanger 31 and the third heat exchanger 41 is located in the upper receiving space 14 (in conjunction with fig. 9), and at least one of the second heat exchanger 32 and the energy storage device 42 is located in the lower receiving space 15. Therefore, the overall layout of the air conditioner 100 is more coordinated, the upper and lower spaces are reasonably utilized, the problem of instability due to light head weight is avoided, and the air conditioner can be stably supported on the ground or can move on the ground.
As shown in fig. 7, the casing 1 may further have an intermediate receiving space 16 therein between the upper receiving space 14 and the lower receiving space 15, and a compressor 33 is located in the intermediate receiving space 16. Therefore, the compressor 33 can be more conveniently connected with the first heat exchanger 31 above the compressor and the second heat exchanger 32 below the compressor, and a refrigerant transportation pipeline is shortened, so that the cost is reduced, the leakage problem of the refrigerant is improved, the transportation reliability of the refrigerant is improved, and the working reliability of the compressor system 3 is improved.
In addition, through establishing compressor 33 in the below of third heat exchanger 41 to guarantee that the height of placing third heat exchanger 41 in last accommodation space 14 is higher, avoid reaching ground fast with the cold air after third heat exchanger 41 exchanges, prolonged the blowing distance and the time of air conditioning promptly, thereby can reduce ambient temperature better, promote user experience. Moreover, by disposing the compressor 33 below the third heat exchanger 41, the center of gravity and vibration of the whole air conditioner can be reduced, so that the air conditioner 100 can operate more smoothly.
As shown in fig. 7, the cabinet 1 may further have an intermediate receiving space 16 therein between the upper receiving space 14 and the lower receiving space 15, and the liquid pumping device 43 is located in the intermediate receiving space 16. Therefore, the liquid pump device 43 can be more conveniently connected with the third heat exchanger 41 above and the energy storage device 42 below, the refrigerant transportation pipeline is shortened, the cost is reduced, the leakage problem of the refrigerant is improved, the transportation reliability of the refrigerant is improved, and the working reliability of the liquid pump system 4 is improved.
In some embodiments, as shown in fig. 5 and 6, the cabinet 1 may include a front surface 11 and a rear surface 12 disposed opposite to each other in a front-rear direction, the air outlet 111 may be formed on the front surface 11, the air inlet 121 may be formed on the rear surface 12, and the air duct 13 is formed in the cabinet 1 and communicates the air inlet 121 and the air outlet 111. Therefore, the processing is convenient, the distance between the air outlet 111 and the air inlet 121 can be increased, and the short circuit of return air is avoided. Of course, the present invention is not limited thereto, and the air outlet 111 and the air inlet 121 may be separately provided at other positions of the casing 1, such as a top wall, a side wall, or the like, so that the design is more flexible.
As shown in fig. 8 and 9, the ventilation device 2, the third heat exchanger 41, and the first heat exchanger 31 are sequentially arranged from front to back, so that it can be ensured that the ventilation device 2 and the third heat exchanger 41 are both close to the air outlet 111, and the first heat exchanger 31 is close to the air inlet 121. Therefore, (1) the third heat exchanger 41 can be ensured to be closer to the air outlet 111, and when the liquid pump system 4 works, the cooling effect of the third heat exchanger 41 can be improved, and the ambient temperature can be better reduced; (2) the distance between the ventilation device 2 and the air outlet 111 can be ensured to be short, when the ventilation device 2 works, the wind resistance of the ventilation device 2 can be reduced, and the ventilation quantity of the ventilation device 2 can meet the requirement; (3) the first heat exchanger 31 and the air inlet 121 can be ensured to be closer, and the heat releasing device 31 arranged close to the air inlet 121 can release heat better through the air inlet 121 on the premise that the air conditioner 100 does not have the ventilation device 2 or the ventilation device 2 does not work, so that the working reliability of the compressor system 3 is improved.
In some embodiments, as shown in fig. 9, the ventilation device 2 may include a plurality of fan assemblies 21 arranged at intervals in the up-down direction. This improves the ventilation effect, increases the heat exchange speed of the first heat exchanger 31 and the third heat exchanger 41, and improves the heat release and cooling speed of the air conditioner 100. Of course, the present invention is not limited thereto, and the ventilation device 2 may also include only 1 fan assembly 21, or include two or more fan assemblies 21, and in addition, the number and the type of the fans included in each fan assembly 21 are not limited, and may be specifically selected according to the actual requirements.
As shown in fig. 8 and 9, the thickness directions of the third heat exchanger 41 and the first heat exchanger 31 may be both the airflow flowing directions of the air duct 13 (the directions from the back to the front as shown in fig. 8), and the third heat exchanger 41 and the first heat exchanger 31 may be arranged side by side, so that the space is saved, and the energy exchange efficiency is high. The third heat exchanger 41 and the first heat exchanger 31 can share fins, so that the assembly and the positioning are simplified, and the energy exchange efficiency is high. The third heat exchanger 41 may not share fins with the first heat exchanger 31, so that flexible assembly and production are possible.
As shown in fig. 9, in some embodiments of the present invention, the thickness directions of the third heat exchanger 41 and the first heat exchanger 31 are both front-rear directions, and the third heat exchanger 41 and the first heat exchanger 31 are arranged side by side in the front-rear direction, that is, the center of the third heat exchanger 41 and the center of the first heat exchanger 31 are on a horizontal line extending in the front-rear direction, and the third heat exchanger 41 is flush with the upper end surface, the lower end surface, the left end surface and the right end surface of the first heat exchanger 31. Therefore, the installation is convenient, and the space is saved.
Furthermore, when the third heat exchanger 41 performs the cooling operation, the third heat exchanger 41 may transmit cooling energy to the first heat exchanger 31, so that the first heat exchanger 31 may also be a cold exchanger with a low temperature, thereby increasing the cooling speed. When the first heat exchanger 31 performs the heat releasing operation, the first heat exchanger 31 may transfer heat to the third heat exchanger 41, so that the third heat exchanger 41 may also be a heat exchange body with a higher temperature, thereby increasing the heat releasing speed. In addition, as shown in fig. 9, in the present embodiment, the number of rows of refrigerant pipes in the third heat exchanger 41 may also be greater than the number of rows of refrigerant pipes in the first heat exchanger 31, so that the cooling effect of the third heat exchanger 41 can be improved, and the cooling speed can be increased.
In the following, a water receiving device 5 and a water pumping device 7 according to some embodiments of the invention are described.
In some embodiments, as shown in fig. 9, the air conditioner 100 may further include a water receiving device 5, and the water receiving device 5 is configured to receive the condensed water dropping from the third heat exchanger 41, that is, when the third heat exchanger 41 performs a cooling operation, the condensed water condensed on the surface of the third heat exchanger 41 due to heat exchange and dropping along the surface of the third heat exchanger 41 may be recovered by the water receiving device 5. Therefore, the circuit loss caused by accumulated water in the air conditioner 100 can be avoided, and the working reliability of the air conditioner 100 is improved.
In some embodiments of the present invention, as shown in fig. 9 and 10, the water receiving device 5 may include a water receiving tray 51 and an atomizer 52, the water receiving tray 51 is used for receiving the condensed water dropping from the third heat exchanger 41, and the atomizer 52 is disposed in the water receiving tray 51 for atomizing the water in the water receiving tray 51. From this, can utilize the comdenstion water of retrieving to carry out the humidification to the air for air conditioner 100 still has the humidification function, powerful, moreover, because the comdenstion water is by recycle, thereby can avoid the user to initiatively discharge the condensate water in water collector 5, perhaps reduces the number of times that the user regularly discharged the condensate water in water collector 5, alleviates user's intensity of labour.
It can be understood that the water droplets atomized by the atomizer 52 are sent out from the air outlet together with the cold air in the air duct 13, thereby achieving the humidification effect. In addition, it is understood that the specific structure and operation of the atomizer 52 are well known to those skilled in the art and will not be described herein.
Here, it should be noted that the water receiving device 5 may directly or indirectly receive the condensed water dropping along the surface of the third heat exchanger 41.
Specifically, when the water catcher 5 is placed directly below the third heat exchanger 41, the water catcher 5 may directly catch the condensed water dropping along the surface of the third heat exchanger 41. For example, in the specific example shown in fig. 11, at least a part of the water pan 51 may be located directly below the third heat exchanger 41, so that the water pan 51 may directly receive the condensed water dropping from the third heat exchanger 41, thereby simplifying the structure and reducing the cost.
In addition, the water receiving device 5 may also indirectly receive the condensed water dropping along the surface of the third heat exchanger 41 through other auxiliary means, and at this time, the water receiving device 5 may not be placed right below the third heat exchanger 41. For example, in the specific example shown in fig. 12, the bottom of the third heat exchanger 41 has a water collection tank 411, and the water collection tank 411 is connected to the water tray 51 through a drainage tube 412. Therefore, the condensed water dropping from the third heat exchanger 41 can be collected in the water collection tank 411 and then flows into the water receiving tray 51 through the drainage tube 412, so that the water receiving tray 51 does not need to be arranged right below the third heat exchanger 41. The invention is not limited to the above, when the drainage tube 412 is adopted to guide water to the water receiving tray 51, the water receiving tray 51 can be arranged right below the third heat exchanger 41, so as to save the occupancy rate of the transverse space.
In some embodiments, as shown in fig. 10 and 11, the drip tray 51 may include: the atomizing nozzle comprises a body 511 and a partition plate 512, wherein the body 511 comprises a bottom wall 5111 and a side wall 5112, a cavity 5113 with an open top is defined between the bottom wall 5111 and the side wall 5112, and the partition plate 512 is arranged in the cavity 5113 to divide the cavity 5113 into an atomizing cavity 5113a and an overflowing cavity 5113b which are positioned at two sides of the partition plate 512.
As shown in fig. 10 and 11, the atomization chamber 5113a is located right below the third heat exchanger 41, the atomizer 52 is disposed in the atomization chamber 5113a, and the water pan 51 is configured such that when the water level in the atomization chamber 5113a exceeds a preset value, the water in the atomization chamber 5113a overflows to the overflow chamber 5113 b. Therefore, the condensed water level in the atomizing chamber 5113a can be ensured to be sufficient to ensure the working effectiveness of the atomizer 52, and the danger of electric leakage and the like caused by overflow due to overhigh water level in the atomizing chamber 5113a can be avoided.
In some specific examples, as shown in fig. 10 and 11, the upper end of the partition plate 512 may be lower than the upper edge of the side wall 5112, so that the water level in the atomizing chamber 5113a is higher than the upper end of the partition plate 512 by more than the preset value, and at this time, the water in the atomizing chamber 5113a may overflow into the overflow chamber 5113b over the upper end of the partition plate 512. Therefore, the overflow can be simply, effectively and quickly realized. Of course, the present invention is not limited thereto, and the water may be overflowed in other manners, for example, an overflow hole may be further disposed on the partition plate 512, and when the water level in the atomizing chamber 5113a exceeds a preset value, the water in the atomizing chamber 5113a may overflow to the overflow chamber 5113b through the overflow hole on the partition plate 512, which will not be described herein again.
In some embodiments of the present invention, as shown in fig. 10 and 11, the water receiving device 5 may further include a water containing box 53, and the water containing box 53 is communicated with the overflow chamber 5113 b. Therefore, the overflow of the water in the overflow chamber 5113b can be avoided, for example, a box with a large volume can be provided as the water containing box 53 to ensure the reliability of the recovery of the condensed water, and the volume of the overflow chamber 5113b may be small at this time, as long as the function of guiding the water from the atomizing chamber 5113a to the water containing box 53 can be achieved.
