The heat pump water heater 300 collects the heat dissipated by the air compressor 110, and water circulation occurs between the secondary water tank 200 and the heat pump water heater 300, realizing the effective utilization of the heat dissipated by the air compressor 110 and reducing the temperature inside the box body 100. The air compressor 110, the cold dryer module 120, and the primary water tank 130 are all integrated inside the box body 100, and the secondary water tank 200 and the heat pump water heater 300 are both integrated on the top of the box body 100, which can effectively reduce the site requirements for equipment installation.

[0036] In the embodiment of the present utility model, an air intake window 101 is installed at the lower left side of the box body 100, and an exhaust window 102 is installed at the upper right side of the box body 100.

[0037] In an embodiment of the present utility model, an air buffer tank 140, a dryer module 150, an air storage tank 160 and an oxygen generator module 170 are also installed in the box body 100. The compressed gas output by the air compressor 110 sequentially passes through the air buffer tank 140, the cold dryer module 120, the dryer module 150, the air storage tank 160, and is finally sent to the oxygen generator module 170.

Installing the air compressor 110 at the front end of the box body 100 according to the position shown in Figure 3 can facilitate the arrangement of other equipment; the oxygen generator module 170 also needs to occupy a large space, but there are many matching equipment for the oxygen generator module 170. If the oxygen generator module 170 is arranged like the air compressor 110, it may be not conducive to personnel entering for subsequent maintenance. Therefore, the oxygen generator module 170 is arranged at the rear end of the box body 100 and close to the right side; correspondingly, the first inspection door 103 is arranged at the front end of the box body 100, and the second inspection door 104 is arranged at the right end of the box body 100, which is convenient for personnel to enter, thereby improving the convenience of subsequent maintenance.

[0039] In an embodiment of the present utility model, the air inlet of the heat pump water heater 300 is connected to the air compressor 110 through an exhaust duct 310. The heat pump water heater 300 is installed corresponding to the air compressor 110 at the front end of the box body 100, and the exhaust duct 310 extends into the box body 100 from the right side of the box body 100; correspondingly, the secondary water tank 200 is installed at the rear end of the box body 100. The volume of the secondary water tank 200 is relatively large. Installing both the secondary water tank 200 and the heat pump water heater 300 above the box body 100 can effectively reduce the floor area. As can be seen from the above, the air compressor 110 is installed at the front end of the box body 100. In order to reduce heat loss and production costs, the heat pump water heater 300 is correspondingly installed at the front end of the box body 100.

[0040] In an embodiment of the present utility model, the air buffer tank 140 and the primary water tank 130 are both installed between the air compressor 110 and the oxygen generator module 170. The air buffer tank 140 is arranged on the left side of the box body 100, and the primary water tank 130 is arranged on the right side of the box body 100; the cold dryer module 120 is arranged on the left side of the box body 100, and the cold dryer module 120 is arranged opposite to the oxygen generator module 170. Specifically, referring to Figure 3 As shown, an electric control cabinet 180 and a power distribution cabinet 190 are installed in the box body 100. The power distribution cabinet 190 is installed at the rear end of the box body 100 and on the left side of the box body 100; the electric control cabinet 180, the air storage tank 160, and the dryer module 150 are combined into an oxygen generation module.

[0041] The gas operation process of the oxygen generation system in this embodiment is as follows:

[0042] S1. External air enters the box body 100 through the air inlet window 101 and is inhaled by the air compressor 110 with integrated heat recovery. The air compressor 110 outputs compressed air to the air buffer tank 140;

[0043] S2. The compressed air is buffered in the air buffer tank 140. A drain valve is provided at the bottom of the air buffer tank, and the drain valve can discharge part of the water in the air buffer tank and reduce the temperature of the compressed air;

[0044] S3. The compressed air in the air buffer tank 140 enters the cold dryer module 120 after passing through a steam-water separator and a primary filter. The steam-water separator and the primary filter are used to drain and filter the compressed air, and the cold dryer module 120 is used to reduce the temperature of the compressed air and dry the compressed air;

[0045] S4. The compressed air processed in the cold dryer module 120 enters the dryer module 150 after passing through a precision filter. The precision filter is used for draining and dust removal, and the dryer module 150 further dries the compressed air;

[0046] S5. The dry compressed air in the dryer module 150 enters the air storage tank 160 after passing through the valve group. The dry compressed air in the air tank enters the oxygen generator module 170 after passing through the valve group to produce high-concentration oxygen.

[0047] As can be seen from the above steps, before the compressed air output by the air compressor 110 enters the oxygen generator module 170, it undergoes multiple cooling treatments and filtration treatments, thereby effectively improving the purity of the compressed air and reducing the pressure of the compressed air. The reduction of the compressed air pressure can significantly reduce the noise generated during the air flow process.

[0048] In the embodiment of the present invention, the air compressor 110 is an air compressor 110 integrated with heat recovery, and the air compressor 110 is preferably a permanent magnet variable frequency motor to reduce the generation of noise. In step S2, the hot air discharged from the air compressor 110 integrated with heat recovery is discharged through the exhaust duct 310 to the inlet of the heat pump water heater 300. The heat pump water heater 300 stores the heat energy of the high-temperature air in the water of the secondary circulation system through the built-in heat energy plate exchanger.

[0049] In the embodiment of the present invention, in step S5, a first muffler is installed at the output end of the dryer module 150, and a second muffler is installed at the output end of the oxygen generator module 170. Specifically, after the dry compressed air in the dryer module 150 enters the valve group, the valve group has a first muffler, and the gas containing a large amount of moisture in the compressed air enters the muffler and is discharged after passing through the valve group; similarly, after the oxygen generator module 170 separates the oxygen in the gas, the remaining gas will enter the second muffler and be discharged. The setting of the first muffler and the second muffler can effectively reduce the noise of the equipment.

[0050] In the embodiment of the present invention, sound insulation materials are installed on the inner side walls of the box body 100, and the sound insulation materials can further reduce the generation of noise. As for the specific selection of the sound insulation materials, it can be selected according to the actual situation.
