Description

Technical Field

[0001] This invention relates to the field of air conditioning, and in particular to a piping module mechanism, an outdoor unit of an air conditioner, and an air conditioning system. Background Technology

[0002] Existing air conditioner outdoor units include multiple components such as compressors, low-pressure tanks, heat exchangers, oil separators, one-way valves, filters, multi-way valves, electrical components, and capillary tubes. All of these components need to be connected through connecting pipes.

[0003] The existing outdoor unit piping of air conditioners has at least the following problems:

[0004] First, installation and maintenance are difficult, inefficient, and costly. This is mainly reflected in the following aspects: (1) There are many connecting pipes and the connection paths are complex and intertwined. Installation and maintenance require on-site operation, which is time-consuming, labor-intensive, and costly. (2) The compressor generates vibration during operation, which causes the pipes to move relative to each other during operation, thereby generating vibration stress. When the vibration stress is large, the fatigue life of the pipes is short and they are prone to breakage or other degrees of damage. When installing and maintaining the pipes, it is necessary to conduct vibration stress tests on these pipes to reduce or eliminate the vibration stress of the pipes and extend the fatigue life of the pipes. When conducting vibration stress tests, it is necessary to arrange the connecting pipes... Vibration strain gauges are installed, but because there are many connecting pipes and the connection paths are complex and intertwined, the cost of installing vibration strain gauges is high and the time is long when conducting vibration stress tests on these pipes. In addition, it is necessary to check and adjust unqualified pipes one by one according to the vibration stress analysis results, which is time-consuming, labor-intensive and costly. (3) The compressor generates vibration during operation, and the pipes also vibrate with the compressor. In order to reduce vibration, it is necessary to install rubber blocks and sheaths on the outside of the connecting pipes one by one to fix and protect the connecting pipes. However, because there are many connecting pipes and the connection paths are complex and intertwined, it is time-consuming, labor-intensive and costly to install rubber blocks and sheaths on these pipes one by one.

[0005] Secondly, the piping occupies a lot of space, making the overall space occupied by the outdoor unit of the air conditioner large. This is mainly reflected in the following aspects: considering the operating space during installation, and the problem that the vibration generated by the compressor will cause adjacent pipes that are too close to each other to rub against each other and cause damage, during the on-site installation of these connecting pipes, it is necessary to reserve a minimum space between the compressor, low-pressure tank and heat exchanger and between adjacent pipes, so that welding guns or coils can be inserted into the space during the pipe welding process, and to avoid pipe rubbing problems. This makes the piping of the outdoor unit of the air conditioner occupy a very large space, thus making the overall space occupied by the outdoor unit of the air conditioner large.

[0006] Third, the operating noise is high; this is mainly due to the vibration generated during the operation of the compressor, and the pipeline also vibrates with the compressor. There are many connecting pipelines and the connection paths are complex. Although some noise can be reduced by adding rubber blocks and sheaths to the outside of the connecting pipelines to fix and protect them, the noise is still very high.

[0007] Fourth, the connecting pipes are prone to corrosion and aging: This is mainly because these pipes are all directly exposed to the external environment, and are prone to corrosion and aging under the influence of weather.

[0008] In summary, the existing piping of outdoor air conditioning units has at least the following problems: difficult installation and maintenance, low efficiency, high cost, large space occupation, high operating noise, and easy corrosion and aging of connecting pipes. Summary of the Invention

[0009] The purpose of this invention is to provide a piping module mechanism and an outdoor unit of an air conditioner, so as to at least alleviate the technical problems of existing air conditioner outdoor unit piping, such as difficult installation and maintenance, low efficiency, high cost, large space occupation, high operating noise, and easy corrosion and aging of connecting pipes.

[0010] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0011] In a first aspect, embodiments of the present invention provide a piping module mechanism, the piping module mechanism including a body, the interior of the body having a functional cavity; the surface of the body having a functional connection port, the functional cavity communicating with the functional connection port; and the interior of the functional cavity having a functional component.

[0012] When this piping module is applied in the air conditioning field, the aforementioned "functional components" mainly refer to fluid transport and control components involved in air conditioning cooling or heating. Functional components include, but are not limited to, at least one of the aforementioned oil separators, check valves, filters, and multi-way valves.

[0013] In this application, the functional component is an accessory that has gas-liquid transmission function and can realize other functions in the air conditioning system. For example, a four-way valve has a transmission function and can realize the function of automatic refrigerant flow reversal; a filter has a refrigerant transmission function and can realize the function of filtering impurities in the refrigerant flow path; a one-way valve has a transmission function and can realize the function of preventing refrigerant backflow; an oil separator has a transmission function and can realize the function of separating the refrigerant and refrigeration oil mixture separately.

[0014] In some possible implementations, the functional cavity of the piping module body may also be provided with other types of fluid transport control components. These other types of fluid transport control components may be connected in parallel or in series with the aforementioned oil separator, check valve, filter or multi-way valve, and may share the functional cavity and functional connection port with the aforementioned oil separator, check valve, filter or multi-way valve, or may use different functional cavities and functional connection ports respectively.

[0015] In some alternative embodiments of this application, the functional components include at least one of an oil separator, a check valve, a filter, and a multi-way valve.

[0016] In this embodiment, by incorporating at least one of the following components—connecting pipes and check valves, oil separators, filters, and multi-way valves—inside the piping module body, the number of exposed pipes in the outdoor unit of the air conditioner is reduced, thereby decreasing the total number of connecting pipes in the piping system. Furthermore, the piping module body can be pre-assembled in the workshop and then assembled on-site, significantly reducing the number of welds during installation. This simplifies installation and maintenance, reducing complexity, time, and costs. Simultaneously, the pipes are housed within the piping module body in a cavity-like structure, preventing interference and relative movement between them. This eliminates vibration stress on the pipes within the piping module body, preventing breakage due to vibration stress caused by mutual movement, extending their fatigue life, and eliminating the need for vibration stress testing of the pipes inside the piping module body during installation and maintenance. This shortens the time required for comprehensive testing of all pipes in the entire piping system. The cycle of vibration stress testing and commissioning is shortened. Furthermore, during installation and maintenance, it is no longer necessary to install rubber blocks and sheaths on the pipes inside the piping module body to fix and protect them, saving costs and further improving installation and maintenance efficiency. In addition, by incorporating at least one of the following components—connecting pipes, check valves, oil separators, filters, and multi-way valves—within the piping module body, the number of exposed pipes on the outdoor unit of the air conditioner is reduced, and the required operating space and anti-wear pipe space are also reduced, thereby reducing the overall space occupied by the piping system and further reducing the overall space occupied by the outdoor unit of the air conditioner. Moreover, the various pipes inside the piping module body are housed in a cavity structure, preventing interference and relative movement between pipes, which greatly reduces the noise generated by the piping during compressor operation. The elimination of exposed pipes inside the piping module body also alleviates the problem of corrosion and aging of these pipes, extending their lifespan.

[0017] In summary, the piping module mechanism provided in this embodiment at least alleviates the technical problems of existing air conditioner outdoor unit piping, such as difficult installation and maintenance, low efficiency, high cost, large space occupation, high operating noise, and easy corrosion and aging of connecting pipes.

For example, a four-way valve has a transmission function and can realize the function of automatic refrigerant flow reversal; a filter has a refrigerant transmission function and can realize the function of filtering impurities in the refrigerant flow path; a one-way valve has a transmission function and can realize the function of preventing refrigerant backflow; an oil separator has a transmission function and can realize the function of separating the refrigerant and refrigeration oil mixture separately.

[0105] In some possible implementations, the functional cavity of the piping module body may also be provided with other types of fluid transport control components. These other types of fluid transport control components may be connected in parallel or in series with the aforementioned oil separator, check valve, filter or multi-way valve, and may share the functional cavity and functional connection port with the aforementioned oil separator, check valve, filter or multi-way valve, or may use different functional cavities and functional connection ports respectively.

[0106] In some alternative embodiments of this application, the functional components include at least one of an oil separator, a check valve, a filter, and a multi-way valve.

[0107] Furthermore, the functional cavity is formed into a shape that is compatible with the aforementioned functional component and can limit the positioning of the aforementioned functional component. Specifically, the functional cavity limits the functional component mainly in order to prevent the functional component from leaving the functional cavity, and at the same time, to prevent the functional component from shaking within the functional cavity except for necessary working principle actions.

[0108] In optional embodiments of this example, the functional cavity includes an oil separation cavity for accommodating an oil separator, and a functional connection port includes an oil separation connection port communicating with the oil separation cavity; and / or, the functional cavity includes a check valve cavity for accommodating a check valve, and a functional connection port includes a check valve connection port communicating with the check valve cavity; and / or, the functional cavity includes a filter cavity for accommodating a filter, and a functional connection port includes a filter connection port communicating with the filter cavity; and / or, the functional cavity includes a multi-way valve cavity for accommodating a multi-way valve, and a functional connection port includes a multi-way valve connection port communicating with the multi-way valve cavity. In this solution, there are various specific ways of "accommodating", including but not limited to, directly inserting and confining the entire oil separator, and / or check valve, and / or filter, and / or multi-way valve, and / or other types of functional components into the corresponding functional cavity, and using the cavity wall of the functional cavity as the housing wall of the oil separator, and / or check valve, and / or filter, and / or multi-way valve, inserting and confining the internal functional components of the oil separator, and / or check valve, and / or filter, and / or multi-way valve, and / or other types of functional components into the corresponding functional cavity.

[0109] The outdoor unit of the air conditioner includes a housing and the aforementioned piping module mechanism, wherein the piping module mechanism is located inside the housing, more specifically, referring to... Figures 1 to 3 The outdoor unit of this air conditioner includes a base 2, a compressor 3, a low-pressure tank 4, and a heat exchanger 5. In addition, the outdoor unit also includes... Figures 1 to 3 The oil separator, check valve, filter, multi-way valve, and piping module (not shown in the diagram) are preferably also present in the outdoor unit of this air conditioner. Figures 1 to 3The diagram shows an electrical control box 11; wherein, the piping module mechanism includes a body, the interior of which is provided with a functional cavity, and the surface of the body is provided with a functional connection port, the functional cavity being connected to the functional connection port, and at least one of the aforementioned four functional components—one-way valve, oil separator, filter, and multi-way valve—is located inside the functional cavity.

[0110] The air conditioning system includes the aforementioned piping module.

[0111] The piping module mechanism provided by this invention reduces the number of exposed pipes on the outdoor unit of the air conditioner by incorporating at least one of the following components: connecting pipes, check valves, oil separators, filters, and multi-way valves. This reduces the total number of connecting pipes in the piping system. Furthermore, the piping module mechanism can be pre-assembled in the workshop and then assembled on-site, significantly reducing the number of welds during installation. This simplifies installation and maintenance, reducing complexity, time, and costs. Simultaneously, the pipes are housed within the piping module mechanism in a cavity structure, preventing interference and relative movement between them. This eliminates vibration stress on the pipes within the module mechanism, preventing breakage due to vibration stress caused by mutual movement, extending their fatigue life, and eliminating the need for vibration stress testing of the pipes within the module mechanism during installation and maintenance. This shortens the time required for vibration testing of all pipes in the entire piping system. The dynamic stress testing and debugging cycle is shortened. Furthermore, during installation and maintenance, it is no longer necessary to install rubber blocks and sheaths on the pipes inside the piping module body to fix and protect them, saving costs and further improving installation and maintenance efficiency. In addition, by incorporating at least one of the following components—connecting pipes, check valves, oil separators, filters, and multi-way valves—within the piping module body, the number of exposed pipes on the outdoor unit of the air conditioner is reduced, and the required operating space and anti-wear pipe space are also reduced, thereby reducing the overall space occupied by the piping system and further reducing the overall space occupied by the outdoor unit of the air conditioner. Moreover, the various pipes inside the piping module body are housed in a cavity structure, preventing interference and relative movement between pipes, which greatly reduces the noise generated by the piping during compressor operation. The elimination of exposed pipes inside the piping module body also alleviates the problem of corrosion and aging of these pipes, extending their lifespan.

[0112] In summary, this invention at least alleviates the technical problems of existing air conditioner outdoor unit piping, such as difficult installation and maintenance, low efficiency, high cost, large space occupation, high operating noise, and easy corrosion and aging of connecting pipes.
