[0025] The electric control device is provided with a display screen, which is at least used to display the operating data of the air-conditioning transformation module, and the display screen is exposed outside the cavity shell.

[0030] The present application also provides a computer room air conditioning system, including the above-mentioned air conditioning transformation module.

[0031] Compared with the prior art, the technical solution provided by this application has at least the following beneficial effects:

[0032] The air conditioning modification module provided in the present application mainly includes a cavity shell, a heat dissipation device, a frequency converter and a compressor. The cavity shell is provided with an air inlet and an air outlet, and the interior of the cavity shell is respectively connected with the air inlet and the air outlet; the heat dissipation device is arranged inside the cavity shell, and the air flow is driven by the heat dissipation device to form a heat dissipation channel flowing from the air inlet to the air outlet; the frequency converter and the compressor are arranged inside the cavity shell, and the frequency converter is located on the path of the heat dissipation channel. The frequency converter is electrically connected to the compressor, and the frequency converter is used to adjust the operating frequency of the compressor.

[0033] In the traditional computer room air conditioning system, since the fixed-frequency air conditioner cannot adjust the operating frequency of the compressor according to the actual heat load changes in the computer room, the air conditioning system still runs at full load under low load or partial load conditions, resulting in a huge waste of energy. This unadjustable operating mode is not only inefficient, but also increases the operating costs of the computer room. To address this problem, this technical solution proposes an air conditioning transformation module, which integrates the inverter and the compressor inside the cavity shell, and uses the inverter to adjust the operating frequency of the compressor to adapt to the actual heat load changes in the computer room, thereby achieving energy saving and consumption reduction.

[0034] The cavity shell in the air conditioning transformation module is designed with an air inlet and an air outlet, so that air can circulate inside the cavity shell, which is the physical basis for forming a heat dissipation channel. The heat dissipation device is arranged inside the cavity shell, and by driving the airflow, a heat dissipation channel is formed from the air inlet to the air outlet. This design not only promotes air circulation, but also improves heat dissipation efficiency. The inverter is located on the path of the heat dissipation channel, so that heat can be effectively extracted from the inverter, ensuring that the equipment operates at an appropriate temperature and avoiding performance degradation or damage due to overheating.

[0035] The inverter is electrically connected to the compressor, and this layout allows the inverter to adjust the compressor's operating frequency in real time. This function of the inverter is crucial to energy conservation because it allows the compressor to dynamically adjust its operating status according to the actual heat load requirements of the computer room. At low loads, the inverter can reduce the compressor's operating frequency to reduce energy consumption; at high loads, the inverter can increase the compressor's operating frequency to meet higher cooling needs. This flexible adjustment mechanism allows the air conditioning system to respond to temperature changes in the computer room more efficiently and reduce unnecessary energy waste.

[0036] Combined with the above structure and process description, it can be seen that the air-conditioning transformation module has at least the following beneficial effects: the air-conditioning transformation module integrates the inverter and the compressor inside the cavity shell, and uses the inverter to adjust the operating frequency of the compressor, thereby effectively solving the problem that the traditional fixed-frequency air-conditioning system cannot adjust the operating state according to the actual load changes, resulting in energy waste, and achieves the beneficial effect of energy saving and consumption reduction.

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of an air-conditioning modification module provided in an embodiment of the present application, and Figure 2 is an internal diagram of the air-conditioning modification module provided in an embodiment of the present application.

[0055] In a first specific implementation, the air conditioning transformation module provided in the implementation scheme of the present application mainly includes a cavity shell 1, a heat dissipation device 2, an inverter 3 and a compressor 4.

[0056] The cavity shell 1 serves as a base for the heat sink 2, the inverter 3 and the compressor 4. The heat sink 2, the inverter 3 and the compressor 4 are arranged inside the cavity shell 1. The cavity shell 1 is provided with an air inlet 11 and an air outlet 12, and the interior of the cavity shell 1 is connected to the air inlet 11 and the air outlet 12 respectively.

[0057] The heat dissipation device 2 is arranged inside the cavity shell 1, and the heat dissipation device 2 drives the airflow to form a heat dissipation channel 13 flowing from the air inlet 11 to the air outlet 12. The inverter 3 and the compressor 4 are arranged inside the cavity shell 1, and the inverter 3 is located on the path of the heat dissipation channel 13. The inverter 3 is electrically connected to the compressor 4, and the inverter 3 is used to adjust the operating frequency of the compressor 4.

[0058] In the traditional computer room air conditioning system, since the fixed-frequency air conditioner cannot adjust the operating frequency of the compressor according to the actual heat load changes in the computer room, the air conditioning system still runs at full load under low load or partial load conditions, resulting in a huge waste of energy. This unadjustable operating mode is not only inefficient, but also increases the operating cost of the computer room. In response to this problem, the present technical solution proposes an air conditioning transformation module, which integrates the inverter 3 and the compressor 4 inside the cavity shell 1, and uses the inverter 3 to adjust the operating frequency of the compressor 4 to adapt to the actual heat load changes in the computer room, thereby achieving the effect of energy saving and consumption reduction.

[0059] The cavity shell 1 in the air conditioning transformation module is designed with an air inlet 11 and an air outlet 12, so that air can circulate inside the cavity shell 1, which is the physical basis for forming the heat dissipation channel 13. The heat dissipation device 2 is arranged inside the cavity shell 1, and by driving the airflow, a heat dissipation channel 13 is formed from the air inlet 11 to the air outlet 12. Such a design not only promotes air circulation, but also improves the heat dissipation efficiency. The inverter 3 is located on the path of the heat dissipation channel 13, so that heat can be effectively extracted from the inverter 3, ensuring that the equipment operates at a suitable temperature and avoiding performance degradation or damage caused by overheating.

[0060] The inverter 3 is electrically connected to the compressor 4. This layout allows the inverter 3 to adjust the operating frequency of the compressor 4 in real time. This function of the inverter 3 is crucial for energy saving because it allows the compressor 4 to dynamically adjust its operating state according to the actual heat load demand of the computer room. At low load, the inverter 3 can reduce the operating frequency of the compressor 4 to reduce energy consumption; at high load, the inverter 3 can increase the operating frequency of the compressor 4 to meet higher cooling needs. This flexible adjustment mechanism enables the air conditioning system to respond to temperature changes in the computer room more efficiently and reduce unnecessary energy waste.

[0061] Combined with the above structure and process description, it can be seen that the air-conditioning transformation module has at least the following beneficial effects: the air-conditioning transformation module integrates the inverter 3 and the compressor 4 inside the cavity shell 1, and uses the inverter 3 to adjust the operating frequency of the compressor 4, thereby effectively solving the problem that the traditional fixed-frequency air-conditioning system cannot adjust the operating state according to the actual load changes, resulting in energy waste, and achieves the beneficial effect of energy saving and consumption reduction.

[0062] In some embodiments, the compressor 4 is located on the path of the heat dissipation channel 13;

[0063] Along the flow direction of the heat dissipation channel 13 , the compressor 4 is located upstream of the inverter 3 .

[0064] In this embodiment, the compressor 4 is specially arranged on the path of the heat dissipation channel 13, and along the flow direction of the heat dissipation channel 13, the compressor 4 is located upstream of the inverter 3. Such a layout means that the compressor 4 and the inverter 3 both directly benefit from the heat dissipation channel 13 formed by the airflow driven by the heat dissipation device 2, and thus also have an efficient heat dissipation effect.

[0065] Since the inverter 3 is located on the path of the heat dissipation channel 13, it can dissipate heat directly from the airflow driven by the heat dissipation device 2. Now, the compressor 4 is also placed on the heat dissipation channel 13 and is located upstream of the inverter 3, which means that the airflow driven by the heat dissipation device 2 will first flow through the compressor 4, take away the heat generated by it, and then flow to the inverter 3. Such an airflow path design not only ensures that the heat generated by the compressor 4 during operation can be quickly taken away, effectively reducing its operating temperature, but also further guarantees the heat dissipation effect of the inverter 3, because after the heat dissipation demand of the compressor 4 is met first, the remaining airflow can still continue to provide heat dissipation for the inverter 3.

[0066] Through this design, the compressor 4 and the inverter 3 share the same heat dissipation channel 13, and the compressor 4 is located upstream. Such a layout optimizes the heat dissipation efficiency, ensures the stable operation of key components in a high temperature environment, extends the service life of the equipment, and improves the reliability and efficiency of the entire air-conditioning transformation module.

[0067] In some embodiments, the air outlet 12 is disposed on the top of the cavity shell 1 , and a height difference from low to high is formed between the air inlet 11 and the air outlet 12 .

[0068] In this embodiment, the air outlet 12 is arranged at the top of the cavity shell 1, and the air inlet 11 is located at the bottom or lower position of the cavity shell 1, so that a height difference from low to high is formed between the air inlet 11 and the air outlet 12. This design defines the direction of the heat dissipation channel 13, that is, the flow direction of the airflow; when the heat dissipation device 2 is working, cold air enters the cavity shell 1 from the air inlet 11 from bottom to top, and inside the cavity shell 1, the cold air dissipates heat to the inverter 3 and the compressor 4, and the hot air after heat exchange leaves from the air outlet 12 from top to top.

[0069] This bottom-in-top-out flow mode has a good effect and matches the natural pressure relationship of hot air rising and cold air sinking. This layout utilizes the principle of hot air rising naturally and cold air sinking naturally, effectively improving the heat dissipation efficiency. The existence of the height difference allows the cold air to naturally sink and flow through the inverter 3 and the compressor 4 after entering the cavity shell 1, taking away the heat, while the hot air naturally rises due to its low density and is discharged through the air outlet 12. This airflow organization method not only improves the heat dissipation efficiency, but also reduces the resistance of airflow, making the entire heat dissipation process smoother and more efficient.

[0070] In some embodiments, the air inlet 11 is provided with a grille structure 111 .

[0071] In this embodiment, the air inlet 11 is provided with a grille structure 111, which effectively blocks foreign matter that may enter the cavity shell 1 along with the airflow. The grille structure 111 improves the purity of the airflow entering the cavity shell 1 through its physical barrier function, and prevents impurities such as dust and debris from directly entering the interior of the air conditioning transformation module, thereby protecting key components such as the heat sink 2, the inverter 3 and the compressor 4 from damage. Such a design not only helps to maintain the cleanliness of the interior of the air conditioning transformation module and reduce maintenance requirements, but also helps to improve the stability and life of the entire system.

[0072] In some embodiments, the air outlet 12 is provided with a grid structure 121 .

[0073] In this embodiment, the air outlet 12 is provided with a grid structure 121. The grid structure 121 also has the function of blocking foreign matter, and it can prevent large particles of debris or foreign matter from entering the cavity shell 1 through the air outlet 12 from the outside. Especially in the embodiment where the air outlet 12 is arranged at the top of the cavity shell 1, the role of the grid structure 121 is particularly important. By providing the grid structure 121 on the air outlet 12, it is possible to prevent foreign matter from falling into the cavity shell 1, thereby avoiding these foreign matter from causing potential damage or blockage to internal components such as the heat sink 2, the inverter 3 and the compressor 4. Such a design not only improves the safety of the air conditioning modification module, but also helps to keep the internal airflow clean, ensuring the heat dissipation efficiency and the stability of equipment performance.

[0074] In some embodiments, the heat dissipation device 2 includes a fan 21;

[0075] At least one fan 21 is disposed at the air outlet 12 , and an air suction surface 211 of the fan 21 is disposed toward the interior of the cavity shell 1 .

[0076] In the present embodiment, this design enables the fan 21 to not only absorb hot air from the interior of the cavity housing 1 , but also to effectively discharge the hot air from the air outlet 12 .

[0077] The location and type of the fan 21 are one of the characteristics of the solution. Placing the fan 21 at the air outlet 12 means that it can accelerate and guide the hot air when it rises to the top of the cavity shell 1, ensuring that the hot air can be discharged quickly and efficiently.

[0078] In some embodiments, at least one fan 21 is disposed at the air inlet 11 , and an exhaust surface of the fan 21 is disposed toward the interior of the cavity shell 1 .

[0079] In the present embodiment, this layout enables the fan 21 to directly pressurize and guide the cold air entering the cavity housing 1, thereby improving the efficiency and speed of air flow.

[0080] This arrangement of the fan 21 not only helps the cold air to enter the cavity shell 1 faster, but also ensures that the cold air can be quickly dispersed after entering the cavity shell 1 and perform heat exchange with heat-generating components such as the inverter 3 and the compressor 4.

[0081] In some embodiments, the chamber housing 1 is further provided with a pipeline through hole 14;

[0082] The inlet of the compressor 4 is connected to the first transport pipe 5, the first transport pipe 5 extends out of the pipeline through hole 14, and is connected to the evaporator through the first transport pipe 5;

[0083] The outlet of the compressor 4 is connected to the second transport pipe 6 , and the second transport pipe 6 extends out of the pipeline through hole 14 and is connected to the condenser through the second transport pipe 6 .

[0084] In this embodiment, the cavity shell 1 is specially designed with a pipeline through hole 14, which allows the compressor 4 to be connected to the external evaporator and condenser through a pipeline. The inlet end of the compressor 4 is connected to the evaporator through the first transport pipe 5, and the first transport pipe 5 passes through the pipeline through hole 14, thereby realizing the pipeline connection between the compressor and the evaporator. Similarly, the outlet end of the compressor 4 is connected to the condenser through the second transport pipe 6, and the second transport pipe 6 also passes through the pipeline through hole 14, thereby ensuring the pipeline connection between the compressor and the condenser.

[0085] This design allows the compressor 4 to effectively inhale low-pressure and low-temperature refrigerant vapor from the evaporator, and after compression, transport the high-pressure hot vapor to the condenser for condensation. The presence of the pipeline through hole 14 not only simplifies the complexity of connecting the compressor to external equipment, but also improves the integration and compactness of the entire system. In addition, this design is also easy to install and maintain, because the connection points of the pipelines are centrally managed, reducing the difficulty and possibility of errors in on-site wiring, and also reducing the complexity of maintenance. Through such a layout, the refrigeration cycle of the entire air conditioning modification module becomes more efficient and reliable.

[0086] Specifically, the first transport pipe 5 and the second transport pipe 6 are copper pipes. The pipeline through hole 14 includes copper pipe holes 141. The number of the copper pipe holes 141 corresponds to the number of the copper pipes. The copper pipes pass through the copper pipe holes 141.

[0087] In some embodiments, the cavity shell 1 is provided with a top surface 101, a first vertical surface 102 and a second vertical surface 103, the edges of the top surface 101 are respectively connected to the first vertical surface 102 and the second vertical surface 103, and the edges of the first vertical surface 102 and the second vertical surface 103 are connected;

[0088] The top surface 101 is provided with an air outlet 12 , the first vertical surface 102 is provided with an air inlet 11 , and the second vertical surface 103 is provided with a pipeline through hole 14 .

[0089] In this embodiment, the structural design of the cavity shell 1 clearly divides the functions of each facade, making the operation and maintenance of the entire air conditioning transformation module more convenient. Specifically, the cavity shell 1 is designed to have three main facades, namely, the top surface 101, the first facade 102, and the second facade 103. The edge of the top surface 101 is connected to the first facade 102 and the second facade 103, and the edges of the first facade 102 and the second facade 103 are also connected to each other, forming a shell with a stable structure and clear functions.

[0090] The top surface 101 is designed as the location of the air outlet 12. This layout allows the hot air to be discharged from the top of the cavity shell 1 after the heat exchange in the heat dissipation channel 13, which conforms to the natural law of hot air rising. It also facilitates the dissipation of heat and improves the heat dissipation efficiency. The first facade 102 is designed as the location of the air inlet 11. The air inlet is set on the front to facilitate the entry of cold air, and it is also more neat and beautiful visually. The second facade 103 is provided with a pipeline through hole 14, which is used for the pipeline connection between the compressor 4 and external equipment such as the evaporator and the condenser. Such a side wiring design makes the pipeline layout more concealed and orderly, convenient for management and maintenance, and also reduces the occupation of the internal space of the cavity shell 1.

[0091] Through such a design, each facade of the cavity shell 1 has a clear functional positioning, which not only improves the overall performance and aesthetics of the air conditioning transformation module, but also greatly facilitates daily maintenance and management. This division of functional surfaces makes the structure of the air conditioning transformation module more reasonable and the operation more humane.

[0092] Specifically, the cavity shell 1 also has a bottom surface, a third facade and a fourth facade, the first facade 102, the second facade 103, the third facade and the fourth facade are located between the top surface 101 and the bottom surface, and the cavity shell 1 is a six-sided closed square structure. Among them, the cavity shell 1 includes a top plate, four side plates and a bottom plate corresponding to the top surface 101, the first facade 102, the second facade 103, the third facade, the fourth facade and the bottom surface respectively, and columns are arranged at the four corners of the top plate and the bottom plate, and the side plates are fixed between the columns and between the top plate and the bottom plate.

[0093] In particular, the air conditioning transformation module further includes an electric control device 7 provided with a display screen 71 . The display screen 71 is also located on the first facade 102 , and the display screen 71 is located above the air inlet 11 .

[0094] In some embodiments, the air conditioning transformation module further includes:

[0095] The electric control device 7 is disposed inside the cavity shell 1 . The electric control device 7 is electrically connected to the frequency converter 3 . The electric control device 7 controls the frequency converter 3 to adjust the operating frequency of the compressor 4 .

[0096] In this embodiment, the design of the air conditioning transformation module further includes an electric control device 7, which is installed inside the cavity shell 1. The main function of the electric control device 7 is to be electrically connected to the inverter 3 and to control the inverter 3, thereby adjusting the operating frequency of the compressor 4. This design allows the compressor 4 to dynamically adjust its operating state according to the actual cooling demand, thereby optimizing the energy efficiency ratio of the air conditioning system.

[0097] Through the integration of the electronic control device 7, the air conditioning transformation module can not only achieve hardware integration, but also achieve precise management at the software control level. The electronic control device 7 can intelligently adjust the working state of the inverter 3 according to the temperature information or other relevant parameters fed back by the sensor, so that the operation of the compressor 4 is more in line with the current working environment, thereby improving the response speed and energy saving effect of the entire system.

[0098] In addition, the addition of the electronic control device 7 also means that the air conditioning transformation module has a higher level of intelligence, can better adapt to different working conditions and requirements, and enhance the flexibility and reliability of the system. This integrated electronic control design simplifies the control process of the system, reduces the difficulty of maintenance, and also provides convenience for possible future functional expansion and upgrading.

[0099] In some embodiments, the electric control device 7 is hinged to the cavity housing 1, and maintenance is facilitated by flipping the electric control device 7 open.

[0100] In this embodiment, the hinged design between the electric control device 7 and the cavity shell 1 not only makes the electric control device 7 easy to maintain, but also provides convenience for maintaining other components inside the cavity shell 1, such as the compressor 4, when the electric control device 7 is flipped open. This design allows maintenance personnel to easily access areas that are usually blocked by the electric control device 7, so as to perform necessary inspection, maintenance or replacement operations.

[0101] Since the electric control device 7 can be flipped out of the cavity shell 1, this design actually increases the operable space inside the cavity shell 1, making maintenance work more direct and efficient. Without sacrificing the control function, by flipping the electric control device 7, maintenance personnel can directly access key components inside the cavity shell 1, which is difficult to achieve in traditional closed designs.

[0102] In addition, this design also means that the compactness of the internal structure of the chamber shell 1 is optimized, saving space. In a limited space, by articulating the electric control device 7, the convenience of maintenance and the compactness of the internal layout are achieved. This design reduces the need for additional maintenance space, making the entire air conditioning transformation module more compact, while also improving the efficiency and convenience of maintenance. Therefore, this design not only improves the user experience, but also optimizes the overall structure and function of the equipment.

[0103] In some embodiments, the electric control device 7 is provided with a display screen 71 , and the display screen 71 is at least used to display the operating data of the air conditioning transformation module, and the display screen 71 is exposed outside the cavity shell 1 .

[0104] In this embodiment, the electric control device 7 not only has the control function, but also integrates a display screen 71 to provide a user interface and information display function. The display screen 71 is at least used to display the operating data of the air conditioning transformation module, such as temperature, humidity, operating frequency of the compressor 4, energy consumption and other key parameters. Such a design allows the user to directly obtain the real-time status and performance data of the air conditioning transformation module from the display screen 71, enhancing the user experience and the convenience of operation.

[0105] Specifically, the pipeline through hole 14 includes a wire inlet hole 142 , through which a cable electrically connected to the electronic control device 7 passes.

[0106] In a specific embodiment, the air conditioning transformation module includes a cavity shell 1 and a heat dissipation device 2, an inverter 3, a compressor 4, a first transport pipe 5, a second transport pipe 6 and an electronic control device 7 arranged inside the cavity shell 1.

[0109] It should be noted that the air conditioning transformation module provided in this embodiment can be used for energy-saving transformation of old computer rooms. The air conditioning transformation module can be combined according to the number of systems to be transformed, including but not limited to a single system and a composite system.

[0110] Currently the most common air-conditioning units on the market are single-system and dual-system. If it is a single-system modification, you only need to set up a single air-conditioning modification module; if it is a dual-system, you only need to set up a combined air-conditioning modification module.

[0111] The following is an explanation using dual system transformation as an example.

[0112] In some embodiments, the chamber housing 1 comprises:

[0113] The first cavity shell unit 110 is provided with an air inlet 11 and an air outlet 12. The first cavity shell unit 110 is provided with a heat dissipation device 2 and a first compressor 4 inside.

[0114] At least one second chamber shell unit 120 is provided with an air inlet 11, the second chamber shell unit 120 is stacked below the first chamber shell unit 110, the interior of the second chamber shell unit 120 is connected to the interior of the first chamber shell unit 110, and the interior of the second chamber shell unit 120 is provided with a second set of compressors 4;

[0115] Among them, the air conditioning transformation module also includes an electronic control device 7 electrically connected to the inverter 3, and the electronic control device 7 is arranged inside the first cavity shell unit 110; the inverter 3 is respectively arranged in the first cavity shell unit 110 and the second cavity shell unit 120, or the inverter 3 is arranged in the first cavity shell unit 110.

[0116] As shown in FIG. 3 and FIG. 4 , the cavity shell 1 is composed of a first cavity shell unit 110 and at least one second cavity shell unit 120 , and these two units work together to achieve dual-system air conditioning transformation.

[0117] The first housing unit 110 is provided with an air inlet 11 and an air outlet 12, which are responsible for the air intake and overall air outlet of the unit. Inside it, a heat sink 2 and a first set of compressors 4 are installed. The heat sink 2 is designed to improve the heat dissipation efficiency of the entire air conditioning transformation module, while the first set of compressors 4 is responsible for the cooling needs of the first system.

[0118] The second housing unit 120 is designed to be stacked below the first housing unit 110, further saving space and optimizing the layout. The second housing unit 120 is provided with an air inlet 11, the interior of which is connected to the interior of the first housing unit 110, ensuring unimpeded air flow.

[0119] It is worth noting that the heat sink 2 is only disposed in the first cavity shell unit 110, which means that the heat sink 2 of the first cavity shell unit 110 will provide heat dissipation services for the second cavity shell unit 120. This design allows two cavity shell units to share the same heat sink 2, thereby reducing the number of components of the entire system and improving space utilization efficiency.

[0120] The air conditioning transformation module further includes an electric control device 7 electrically connected to the inverter 3, which is located inside the first cavity shell unit 110 and is responsible for controlling the working state of the inverter 3. The inverter 3 can be respectively arranged in the first cavity shell unit 110 and the second cavity shell unit 120 as needed, or all arranged in the first cavity shell unit 110 to adapt to different transformation requirements and configurations.

[0121] With this design, the air conditioning transformation module can flexibly adapt to the needs of dual-system transformation while maintaining a compact structure and efficient heat dissipation. The design of the shared heat dissipation device 2 not only saves space, but also reduces costs, making the entire transformation process more economical and efficient. This modular and integrated design makes the dual-system air conditioning transformation of old computer rooms simpler and more efficient.

[0122] Please refer to Figure 5, which is an internal diagram of the first cavity shell unit and the second cavity shell unit provided in an embodiment of the present application.

[0123] As shown in Figure 5, inverters 3 are respectively arranged in the first cavity shell unit 110 and the second cavity shell unit 120. The inverters 3 are electrically connected to the electronic control device 7 in the first cavity shell unit 110, the inverter 3 in the first cavity shell unit 110 is electrically connected to the compressor 4 in the first cavity shell unit 110, and the inverter 3 in the second cavity shell unit 120 is electrically connected to the compressor 4 in the second cavity shell unit 120. At this time, there is a shorter wiring distance between the inverter 3 and the compressor 4.

[0124] Please refer to Figure 6, which is an internal diagram of the first cavity shell unit and the second cavity shell unit provided in an embodiment of the present application.

[0125] As shown in Figure 6, the inverters 3 are all arranged in the first cavity shell unit 110, and the inverters 3 are all electrically connected to the electronic control device 7 in the first cavity shell unit 110. The compressors 4 in the first cavity shell unit 110 and the second cavity shell unit 120 are respectively electrically connected to the corresponding inverters 3 in the first cavity shell unit 110. At this time, there is a shorter wiring distance between the electronic control device 7 and the inverter 3.

[0126] Optionally, the first cavity shell unit 110 and the second cavity shell unit 120 are fixed by bolts.

The system adopts a variable frequency compressor module, retains the evaporator and condenser of the original system, reduces the transformation cost, and significantly improves the energy-saving effect. The modular design enables the system to flexibly adapt to the air conditioning transformation needs of different system numbers. The transformation process is rapid and easy, which improves the transformation efficiency.
