[0035] A split type air conditioner outdoor unit with noise reduction and heat recovery function, including refrigerant pipeline system assembly 1, condenser 2, embedded waterproof frequency conversion electric control box 3, control box side plate 4, water collecting bottom disc 5, bottom disc support 6, overhauling side plate 8, top plate 9, control box side plate 4, overhauling side plate 8, water collecting bottom disc 5, top plate 9 form the peripheral structure, embedded waterproof frequency conversion electric control box 3 is arranged on water collecting bottom disc 5 and control box side plate 4, and is arranged in the peripheral structure, bottom disc support 6 is arranged below water collecting bottom disc 5, condenser 2 and refrigerant pipeline system assembly 1 are arranged on water collecting bottom disc 5, and refrigerant pipeline system assembly 1 is arranged in the space formed by condenser 2, embedded waterproof frequency conversion electric control box 3, overhauling side plate 8, water collecting bottom disc 5 and top plate 9.

[0036] The material of control box side plate 4, overhauling side plate 8, water collecting bottom disc 5 and top plate 9 is foamed board.

[0037] The overhauling side plate 8 is provided with an overhauling door plate 7.

[0038] The refrigerant pipeline system assembly 1 comprises a compressor 1-1, an oil separator 1-2, a gas-liquid separator 1-3, and a four-way valve 1-5; the compressor 1-1 is connected with the oil separator 1-2 through a pipeline, the oil separator 1-2 is connected with the four-way valve 1-5 through a pipeline, the four-way valve 1-5 is connected with a condenser 2 through a pipeline, the condenser 2 is connected with an electronic expansion valve 1-4 through a pipeline, the electronic expansion valve 1-4 is connected with an indoor unit through a pipeline, the indoor unit is connected with the four-way valve 1-5 through a pipeline, the four-way valve 1-5 is connected with the gas-liquid separator 1-3 through a pipeline, and the gas-liquid separator 1-3 is connected with the compressor 1-1 through a pipeline.

[0039] The compressor 1-1 and the oil separator 1-2 are installed on the water receiving base 5. The oil separator 1-2 is a filtering type oil separator 1-2. The compressor 1-1 is a full direct-current variable frequency high-speed compressor 1-1. One side of the water receiving base 5 is provided with a drain pipe 5-1.

[0040] As shown in Figure 1 , a split type air conditioner outdoor unit with noise reduction and heat recovery functions, a refrigerant pipeline system assembly 11 comprises a compressor 1-1, an oil separator 1-2, and a gas-liquid separator 1-3. The entire copper pipeline system assembly is placed in the internal space of a condenser 2, an embedded waterproof variable frequency electric control box 3, a control box side plate 4, a water receiving base 5, a base support 6, an inspection door plate 7, an inspection side plate 8, and a top plate 9, effectively isolating the electromagnetic and mechanical noise generated by the compressor 1-1 during high-speed operation, and ensuring the running comfort.

[0041] As shown in Figure 3 , a split type air conditioner outdoor unit with noise reduction and heat recovery functions, the embedded waterproof variable frequency electric control box 3 is fixed by the control box side plate 4 and the water receiving base 5. The structure is interlocked by bolt connection.

[0042] As shown in Figure 1 , a split type air conditioner outdoor unit with noise reduction and heat recovery functions, the compressor 1-11-1 is a full direct-current variable frequency high-speed compressor 1-1, which has a more stable driving mode and reduces the vibration and noise that may be generated by traditional alternating current motors. The characteristics of low noise and low vibration make the full direct-current variable frequency high-speed compressor 1-1 more suitable for occasions that require a quiet environment, such as bedrooms, libraries, operating rooms, etc. When using the full direct-current variable frequency high-speed compressor 1-1, users can enjoy a more quiet and comfortable use environment.

From four-way valve 1-5, it flows to gas-liquid separator 1-3, and then back to compressor 1-1. The gas and liquid pipes for the refrigerant cycle are identical to those of traditionally labeled machines.

[0044] like Figure 4 As shown, a split-type air conditioner outdoor unit with noise reduction and heat recovery functions includes an oil separator 1-2, which is a filter-type oil separator. Utilizing the capillary action of fiber materials and the microporous effect of filter paper, it can efficiently separate oil from the gas. Compared to other types of oil separators 1-2, the filter-type oil separator 1-2 maintains a lower loss rate during the separation process, ensuring effective utilization of the oil.

[0045] like Figure 5 As shown, a split-type outdoor air conditioner with noise reduction and heat recovery functions uses a hollow, detachable base 5 for receiving water. This base not only receives condensate formed by the condensation of air in the low-temperature section of the refrigerant piping system component 1, which is then discharged through the drain pipe 5-1, but also uses the detachable base as a support structure for the refrigerant piping system component 1, saving the structural space of the old matching water pan and base bracket 6.
