An embedded air conditioner according to an embodiment of the present invention, which can be used in an indoor environment such as a kitchen, is described below with reference to fig. 1 to 5, and is integrally embedded in a cabinet.
As shown in fig. 1 to 5, an embedded air conditioner according to an embodiment of the present invention includes: the device comprises a compressor 2, a first heat exchanger 31, a phase-change heat storage heat exchanger 1, a throttling device and a box body 5.
The cabinet 5 has an air supply opening 54 and an air return opening 55, and the cabinet 5 is adapted to be inserted into a cabinet, thereby more effectively utilizing the kitchen space and being beautiful. The embedded air conditioner and the cabinet can be aligned at one time during decoration, and the whole kitchen has stronger integration.
The compressor 2, the first heat exchanger 31, the phase-change heat storage heat exchanger 1 and the throttling device are all arranged in the box body 5, and the refrigerating system pipeline is laid in the box body 5. That is, the embedded air conditioner has an integrated structure, the integrated structure is more compact, an indoor unit and an outdoor unit are not required to be singly arranged, and the installation is convenient.
The compressor 2, the phase-change heat storage heat exchanger 1, the throttling device and the first heat exchanger 31 are connected to form a refrigerant circulation loop, and the compressor 2, the phase-change heat storage heat exchanger 1, the throttling device and the first heat exchanger 31 can be communicated through copper pipes.
The first heat exchanger 31 is arranged between the air supply port 54 and the air return port 55, and in the working process, air enters and exits the box 5 through the air return port 55 and the air supply port 54 and exchanges heat with the first heat exchanger 31 so as to realize indoor air temperature adjustment. For example, the first heat exchanger 31 may be an air-cooled heat exchanger, and a fan of the air-cooled heat exchanger pumps outside air into the box 5 and exchanges heat with the refrigerant in the first heat exchanger 31, and then blows the air into the room from the air supply port 54.
The compressor 2 has a discharge port 22 and a suction port 21, and the refrigerant after heat exchange can enter the compressor 2 through the suction port 21, and can be discharged through the discharge port 22 after being compressed by the compressor 2, and it is noted that the construction and operation principle of the compressor 2 are well known to those skilled in the art, and will not be described in detail herein.
The refrigerant circulation circuit of the built-in air conditioner is described below with reference to fig. 5. Specifically, one of the first end (e.g., the left end shown in fig. 5) of the first heat exchanger 31 and the first end (e.g., the upper end shown in fig. 5) of the phase-change heat storage heat exchanger 1 may be connected to the exhaust port 22, the other of the first end of the first heat exchanger 31 and the first end of the phase-change heat storage heat exchanger 1 may be connected to the suction port 21, and the throttling means may be provided between the second end (e.g., the right end shown in fig. 5) of the first heat exchanger 31 and the second end (e.g., the lower end shown in fig. 5) of the phase-change heat storage heat exchanger 1. I.e. the second end of the first heat exchanger 31 and the second end of the phase change heat storage heat exchanger 1 may be connected to the two ends of the restriction device, respectively.
When the refrigerant flows through the first heat exchanger 31, the refrigerant exchanges heat with air, so that the purpose of refrigeration or heating is achieved. After the refrigerant enters the phase-change heat storage heat exchanger 1, the refrigerant can exchange heat with the phase-change medium in the phase-change heat storage heat exchanger 1, heat is stored and released through the change of the phase state of the refrigerant after the phase-change medium absorbs or releases heat, and the refrigerant does not need to exchange heat with the environment after exchanging heat in the phase-change heat storage heat exchanger 1, so that the embedded air conditioner does not need to release heat to the environment during refrigeration and does not need to absorb heat from the environment during heating, the integrated structure of the embedded air conditioner can be realized, and the conventional split structure of the traditional air conditioner is broken.
For example, the built-in air conditioner may provide the user with cold when the suction port 21 is connected to the first end of the first heat exchanger 31 and the discharge port 22 is connected to the first end of the phase change heat storage heat exchanger 1. The high-temperature and high-pressure gaseous refrigerant discharged from the discharge port 22 may first flow to the phase-change heat storage heat exchanger 1, form a liquid refrigerant after exchanging heat with the phase-change medium in the phase-change heat storage heat exchanger 1, and flow from the phase-change heat storage heat exchanger 1 to the throttling device, form a low-temperature and low-pressure liquid refrigerant after being throttled and depressurized by the throttling device, and flow to the first heat exchanger 31, and the refrigerant exchanges heat with air in the first heat exchanger 31 to provide cold energy to a user and form a gaseous refrigerant, and then returns to the compressor 2 from the suction port 21.
Accordingly, when the suction port 21 is connected to the first end of the phase change heat storage heat exchanger 1 and the discharge port 22 is connected to the first end of the first heat exchanger 31, the built-in air conditioner can supply heat to a user.
According to the embedded air conditioner disclosed by the embodiment of the invention, heat is not required to be released to the environment during refrigeration and is not required to be absorbed from the environment during heating, so that the embedded air conditioner realizes an integrated design, is installed in a cabinet, does not occupy extra space of the kitchen, and is good in decoration.

The air supply port 54 is disposed above the air return port 55, the first heat exchanger 31 is an air-cooled heat exchanger, the first heat exchanger 31 is connected to the front wall of the box 5, and the first heat exchanger 31 is located right behind the air supply port 54, in other words, a projection of the first heat exchanger 31 on the front wall of the box 5 and an installation position of the air supply port 54 on the front wall of the box 5 have a superposition area, and a projection of the first heat exchanger 31 and the air return port 55 on the front wall of the box 5 has no superposition area. The air flow moves smoothly, and the heat exchange efficiency is high.
In some alternative embodiments, as shown in fig. 3, the box 5 is a cuboid, the phase-change heat storage heat exchanger 1 and the compressor 2 are arranged at the rear of the box 5 and are spaced apart from each other along the left-right direction, and the first heat exchanger 31 is arranged at the front of the box 5. Correspondingly, the length, width and height of the box body 5 are a, b and c respectively, and the requirements are as follows: b is more than or equal to 0.5a and less than or equal to 0.5b and less than or equal to 2b, and c is more than or equal to 0.3a and less than or equal to 2a.
In other alternative embodiments, as shown in fig. 4, the tank 5 is rectangular, the phase-change heat storage heat exchanger 1 is disposed at the rear of the tank 5, the first heat exchanger 31 is disposed at the front of the tank 5, and the compressor 2 and the pipeline of the refrigerant circulation circuit are disposed between the phase-change heat storage heat exchanger 1 and the first heat exchanger 31. Correspondingly, the length, width and height of the box body 5 are a, b and c respectively, and the requirements are as follows: a is more than or equal to 0.5b and less than or equal to 0.5a and less than or equal to 2a, c is more than or equal to 0.3b and less than or equal to 2b.
In a specific embodiment, the case 5 may be designed as a square, or a rectangular solid having substantially equal length, width, and height. It will be appreciated that the shape of the cabinet 5, and thus the arrangement of the components within the cabinet 5, is designed according to the specific dimensions of the cabinet.
The first heat exchanger 31 can adopt the special fin of the kitchen air conditioner, the fin interval is wider, the surface is smooth and difficult to accumulate oil, the kitchen oil fume environment can be dealt with to a certain extent, and the influence of oil fume on the air conditioner can be reduced by combining the high-efficiency filter screen which is oil-resistant and easy to clean.
As shown in fig. 4 and 5, the built-in air conditioner according to some preferred embodiments of the present invention further includes: the reversing unit 4, the reversing unit 4 includes a first interface 41, a second interface 42, a third interface 43 and a fourth interface 44, the compressor 2 has an air suction port 21 and an air discharge port 22, the air discharge port 22 is connected with the first interface 41, the air suction port 21 is connected with the third interface 43, one end of the first heat exchanger 31 is connected with the second interface 42, one end of the phase change heat storage heat exchanger 1 is connected with the other end of the first heat exchanger 31 through a throttling device, and the other end of the phase change heat storage heat exchanger 1 is connected with the fourth interface 44.
Wherein the first interface 41 may be in commutating communication with one of the second interface 42 and the fourth interface 44, and the third interface 43 may be in commutating communication with the other of the second interface 42 and the fourth interface 44. For example, when the first interface 41 communicates with the second interface 42, the third interface 43 communicates with the fourth interface 44; when the first port 41 communicates with the fourth port 44, the third port 43 communicates with the second port 42. Thereby, the embedded air conditioner can be switched between the cooling mode and the heating mode. Alternatively, the reversing unit 4 may be a four-way reversing valve, but is not limited thereto.
Specifically, when the embedded air conditioner is operated to cool, the first interface 41 of the reversing unit 4 communicates with the fourth interface 44, and the third interface 43 communicates with the second interface 42. The refrigerant passes through the exhaust port 22 of the compressor 2, the first interface 41, the fourth interface 44, the phase change heat storage heat exchanger 1, the throttling device, the first heat exchanger 31, the second interface 42 and the third interface 43 of the reversing unit 4 in sequence, and finally returns to the compressor 2 from the air suction port 21 of the compressor 2, and circulates in this way. The first heat exchanger 31 is now an evaporator and the phase change heat storage heat exchanger 1 is a condenser. When the refrigerant flows through the phase-change heat storage heat exchanger 1, heat exchange is carried out between the refrigerant and the phase-change medium, heat emitted by the refrigerant is absorbed and stored by the phase-change medium, and the state of the phase-change medium changes, for example, the phase-change medium can be changed from a solid state to a liquid state. When the refrigerant flows through the first heat exchanger 31, the refrigerant exchanges heat with air and absorbs heat in the air, so that the purpose of refrigeration is achieved.
When the embedded air conditioner is operated to heat, the switching of the flow direction of the refrigerant can be realized through the reversing unit 4, the first interface 41 and the second interface 42 of the reversing unit 4 are communicated, and the third interface 43 and the fourth interface 44 are communicated. In the process, the refrigerant sequentially passes through the exhaust port 22 of the compressor 2, the first interface 41, the second interface 42, the first heat exchanger 31, the throttling device, the phase-change heat storage heat exchanger 1, the fourth interface 44 and the third interface 43 of the reversing unit 4, and finally returns to the compressor 2 from the air suction port 21 of the compressor 2, and circulates in this way. The phase change heat storage heat exchanger 1 is now an evaporator and the first heat exchanger 31 is a condenser. When flowing through the phase-change heat storage heat exchanger 1, the refrigerant exchanges heat with the phase-change medium, absorbs heat stored in the phase-change medium, and changes the state of the phase-change medium, for example, from a liquid state to a solid state. When the refrigerant flows through the first heat exchanger 31, heat exchange is performed with air, and heat is released into the air, so that the purpose of heating is achieved.
In the process of operating and refrigerating the air conditioner, the phase change medium absorbs and stores condensation heat, and the state of the phase change medium is changed from solid state to liquid state. When the phase-change medium is completely converted into a liquid state, the heat storage capacity of the phase-change medium reaches the upper limit, at the moment, the air conditioner cannot continue to refrigerate, and the air conditioner needs to start the first regeneration process to recover the heat storage capacity of the phase-change medium, and of course, when the phase-change medium is not completely converted into the liquid state, if cooking is finished, the first regeneration process can also be started, so that the heat storage capacity of the phase-change heat storage heat exchanger 1 reaches the maximum. The process is similar to battery charging, and the phase change medium can be completely converted from liquid state to solid state in a short time, and the heat storage capacity is restored again, so that the air conditioner can continue refrigerating. The first regeneration process of the phase-change medium is realized by starting the heating cycle of the air conditioner after stopping the refrigeration cycle of the air conditioner, so that the refrigerant absorbs the heat stored by the phase-change medium, the phase-change medium is changed from a liquid state to a solid state, and the heat storage capacity is recovered. The regeneration process may be initiated when the air conditioning unit does not need to be cooled, for example, during the night time period. Because the kitchen can send hot air into in the first regeneration process, the doors and windows communicated with the kitchen and the indoor space are closed, and heat is prevented from entering other indoor spaces. The window that kitchen and outdoor intercommunication can open for the circulation of air, and the outdoor air can take away the kitchen heat simultaneously.
Also, during the operation of the air conditioner for heating, the phase change medium is changed from a liquid state to a solid state due to the heat absorbed from the phase change medium by the refrigerant. When the phase-change medium is completely converted into a solid state, the heat release capacity of the phase-change medium reaches the upper limit, at the moment, the air conditioning system component cannot continue heating, and the air conditioning system component needs to start the second regeneration process to enable the phase-change medium to recover the heat release capacity, and of course, when the phase-change medium is not completely converted into the solid state, if cooking is completed, the second regeneration process can also be started, so that the heat release capacity of the phase-change heat storage heat exchanger 1 reaches the maximum. The second regeneration process is opposite to the first regeneration process, so that the phase-change medium can be completely converted into liquid state from solid state in a short time, and the heat release capacity is restored again, and the air conditioner can continue heating. The method is realized by stopping the heating cycle of the air conditioner, starting the refrigerating cycle of the air conditioner, absorbing and storing the condensation heat by the phase change medium in the process, and converting the phase change medium from solid state to liquid state, thereby recovering the heat release capacity. This second regeneration process is typically initiated when the air conditioning unit does not require heating. Because the kitchen can send cold air into in the second regeneration process, doors and windows communicated with the kitchen and the room are required to be closed, and cold air is prevented from entering other indoor spaces. The windows in the kitchen and the outside are opened for ventilation.
Thus, by providing the reversing unit 4, the mode of the embedded air conditioner can be switched conveniently, so that the cooling capacity or the heat can be provided by the embedded air conditioner as required. Meanwhile, the regeneration function can be realized by switching the mode of the embedded air conditioner, so that the heat storage and heat release capacities of the phase change medium can be restored again.
According to some embodiments of the invention, referring to fig. 1 and 5, the throttling means comprises a first throttling element 63 and a third throttling element 69. The embedded air conditioner further comprises: a first throttling branch and a third throttling branch. The first throttle leg is provided with a first non-return valve 61 and the third throttle leg is provided with a third non-return valve 67.
Specifically, one end (e.g., the left end in fig. 5) of the first throttling branch is connected to the first heat exchanger 31, and the other end (e.g., the right end in fig. 5) of the first throttling branch is connected to the phase change heat storage heat exchanger 1. The first throttling element 63 is connected in series with the first check valve 61 on the first throttling branch, the first check valve 61 being located at an end of the first throttling element 63 adjacent to the phase change heat storage heat exchanger 1 to enable the refrigerant in the phase change heat storage heat exchanger 1 to flow to the first throttling element 63. A first dry filter 62 may be further provided between the first throttling element 63 and the first check valve 61, and the first dry filter 62 is used for absorbing moisture in the refrigerant.
The third throttling branch is connected in parallel with the first throttling branch between the first heat exchanger 31 and the phase change heat storage heat exchanger 1, a third throttling element 69 and a third one-way valve 67 are connected in series on the third throttling branch, and the third one-way valve 67 is positioned at one end of the third throttling element 69 adjacent to the first heat exchanger 31 so that the refrigerant in the first heat exchanger 31 flows to the third throttling element 69. A third dry filter 68 may be further provided between the third throttling element 69 and the third check valve 67, the third dry filter 68 being for absorbing moisture in the refrigerant.
Therefore, the first throttling element 63 can throttle and reduce the pressure of the refrigerant in the refrigerating process, and the third throttling element 69 can throttle and reduce the pressure of the refrigerant in the heating process, so that different throttling elements can be selected to throttle and reduce the pressure of the refrigerant in the refrigerating process and the refrigerant in the heating process respectively, the throttling and reducing effects are ensured, and the refrigerating and heating performances of the air conditioning system component are improved.
Alternatively, the first and third throttling elements 63 and 69 may be capillary tubes, thermal expansion valves, electronic expansion valves, or the like.
