[0027] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following combination Figure 1 The utility model is described as an air supply system for an air suspension compressor.

[0029] like Figure 1 As shown, the air supply system for an air suspension compressor provided by an embodiment of the present invention includes an air supply tank 1 , a first connecting pipeline 3 and a second connecting pipeline 5 .

[0030] Specifically, the gas supply tank 1 is used to store refrigerant, and the gas supply tank 1 has an inlet and an outlet for the refrigerant to enter and exit the gas supply tank 1 .

[0031] A first connecting line 3 is provided between the refrigerant source and the gas supply tank 1. A first end of the first connecting line 3 is connected to the refrigerant source, and a second end of the first connecting line 3 is connected to the inlet of the gas supply tank 1. A power element 4 is provided on the first connecting line 3 for transporting refrigerant from the refrigerant source to the gas supply tank 1.

[0032] The power element 4 may be, but is not limited to, a gear pump.

[0033] At least two heating elements 2 are installed in the gas supply tank 1. These heating elements 2 heat the refrigerant in the tank, causing it to expand and increase pressure. The heating elements 2 are spaced apart within the tank 1 to fully heat the refrigerant.

[0034] The second connecting pipe 5 is arranged between the air supply tank 1 and the air suspension compressor 6. The first end of the second connecting pipe 5 is connected to the outlet of the air supply tank 1, and the second end of the second connecting pipe 5 is connected to the air inlet of the air floating bearing of the air suspension compressor 6, so that the refrigerant in the air supply tank 1 can enter the air floating bearing of the air suspension compressor 6, thereby realizing the air supply to the air floating bearing of the air suspension compressor 6.

[0035] In this arrangement, the power element 4 is used to transport the refrigerant source to the air supply tank 1, and at least two heating elements 2 are used to heat the refrigerant at different positions in the air supply tank 1. The heating is sufficient, which effectively improves the heating efficiency of the refrigerant, improves the expansion efficiency of the refrigerant, and improves the speed of establishing the pressure difference between the air suspension compressor 6 and the air supply tank 1 of the air supply system, which is conducive to the rapid start-up of the air suspension compressor 6 and solves the problem of slow speed of establishing the pressure difference between the air suspension compressor 6 and the air supply tank 1 of the air supply system in the prior art.

[0036] In this embodiment, the heating element 2 may be an electric heater or an electromagnetic heater, without specific limitation.

[0037] In the embodiment of the present invention, the heating elements 2 are spaced apart along the distribution direction of the inlet and outlet of the gas supply tank 1, and the extension direction of each heating element 2 is perpendicular to the distribution direction of the heating elements 2. As the refrigerant enters the gas supply tank 1 and flows out of the gas supply tank 1, it can flow through each heating element 2 in sequence and fully contact each heating element 2, thereby increasing the contact area between the heating elements 2 and the refrigerant and facilitating improved heating efficiency of the refrigerant.

[0038] In this embodiment, the inlet and outlet of the gas supply tank 1 are arranged on the side wall of the gas supply tank 1. The inlet and outlet of the gas supply tank 1 are arranged opposite each other, and the inlet and outlet of the gas supply tank 1 are located at one end of the gas supply tank 1 near the bottom. This improves the flow path of the refrigerant in the gas supply tank 1 and facilitates sufficient heating of the refrigerant.

[0039] When the air-suspended compressor 6 is applied to a refrigeration system, the refrigeration system also includes a condenser 7 and an evaporator 9. The condenser 7 of the refrigeration system where the air-suspended compressor 6 is located can be used as a refrigerant source, so that the first end of the first connecting pipe 3 is connected to the bottom wall of the condenser 7. When the power element 4 is running, the refrigerant in the condenser 7 can be transported to the air supply tank 1.

[0040] In this embodiment, the air supply system for the air-suspended compressor also includes a third connecting pipe 8, which is arranged between the air-suspended bearing of the air-suspended compressor 6 and the evaporator 9 of the refrigeration system where the air-suspended compressor 6 is located, so that the first end of the third connecting pipe 8 is connected to the air outlet of the air-suspended bearing, and the second end of the third connecting pipe 8 is connected to the evaporator 9 of the refrigeration system where the air-suspended compressor 6 is located.

[0041] The refrigerant at the air bearing of the air-suspended compressor 6 can flow to the evaporator 9. The air supply system for the air-suspended compressor takes the refrigerant from the condenser 7 of the refrigeration system and returns the refrigerant to the evaporator 9 of the refrigeration system, thereby realizing the recycling of the refrigerant, ensuring the balance of the refrigerant amount in the refrigeration system, and not affecting the external environment.

[0042] In the embodiment of the present invention, a pressure detection element 10 and a liquid level detection element 11 are provided in the gas supply tank 1. The pressure detection element 10 is used to detect the pressure in the gas supply tank 1, and the liquid level detection element 11 is used to detect the liquid level of the refrigerant in the gas supply tank 1.

[0043] A first valve 12 is provided at the outlet end of the power element 4. The air supply system for the air suspension compressor further includes a fourth connecting line 13, which is provided between the first connecting line 3 and the evaporator 9 of the refrigeration system where the air suspension compressor 6 is located. A first end of the fourth connecting line 13 is connected to the first connecting line 3, and the first end of the fourth connecting line 13 is located between the power element 4 and the first valve 12. A second end of the fourth connecting line 13 is connected to the evaporator 9, and a second valve 14 is provided on the fourth connecting line 13.

[0044] The second valve 14 is controlled to be in the closed state, and the first valve 12 is controlled to be in the open state, so that the refrigerant delivered by the power element 4 can enter the gas supply tank 1. The first valve 12 is controlled to be in the closed state, and the second valve 14 is controlled to be in the open state, so that the refrigerant delivered by the power element 4 can enter the evaporator 9.

[0045] The first valve 12 and the second valve 14 are both solenoid valves, and the first valve 12, the second valve 14, the pressure detection element 10 and the liquid level detection element 11 are all electrically connected to the controller. The conduction state of the first valve 12 and the second valve 14 can be automatically controlled according to the pressure and liquid level in the gas supply tank 1 to ensure the normal and stable operation of the gas supply system for the air suspension compressor.

[0046] For example, when the liquid level in the gas supply tank 1 is greater than a first preset value, the first valve 12 is controlled to switch to the closed state, and the second valve 14 is controlled to switch to the open state. When the liquid level in the gas supply tank 1 is less than or equal to a second preset value, the first valve 12 is controlled to switch to the open state, and the second valve 14 is controlled to switch to the closed state.

[0047] When the pressure in the gas supply tank 1 is greater than a third preset value, the first valve 12 is controlled to switch to the closed state, and the second valve 14 is controlled to switch to the open state. When the pressure in the gas supply tank 1 is less than or equal to a fourth preset value, the first valve 12 is controlled to switch to the open state, and the second valve 14 is controlled to switch to the closed state.

[0048] A safety valve 17 is also provided on the gas supply tank 1. When the pressure in the gas supply tank 1 exceeds the limit, the safety valve 17 is activated to discharge part of the refrigerant in the gas supply tank 1, thereby ensuring the safety of the gas supply system for the air suspension compressor.

[0049] In this embodiment, a one-way valve 15 is provided on each of the first connecting pipeline 3 , the second connecting pipeline 5 and the fourth connecting pipeline 13 .

[0050] The one-way valve 15 on the first connecting line 3 is located between the first valve 12 and the gas supply tank 1 . The one-way valve 15 on the first connecting line 3 only allows the refrigerant to flow from the condenser 7 to the gas supply tank 1 .

[0051] The one-way valve 15 on the second connecting line 5 only allows the refrigerant in the air supply tank 1 to flow to the air bearing of the air suspension compressor 6 , and the one-way valve 15 on the fourth connecting line 13 only allows the refrigerant in the condenser 7 to flow to the evaporator 9 .

[0052] In this embodiment, a filter 16 is provided on the first connecting pipe 3. The filter 16 is provided at the inlet end of the power element 4. Before the refrigerant in the condenser 7 enters the gear pump, it will pass through the filtering effect of the filter 16 to filter out impurities in the refrigerant, thereby preventing impurities from entering the gear pump, the air supply tank 1 and the air bearing of the air suspension compressor 6, thereby preventing impurities from damaging the air bearing of the air suspension compressor 6 and extending the service life of the air bearing and the air suspension compressor 6.

[0053] Taking the air supply system for an air suspension compressor provided in an embodiment of the present invention as an example in which two heating elements 2 are provided in the air supply tank 1, the operation process of the air supply system for an air suspension compressor provided in an embodiment of the present invention is described as follows.

[0054] When the air suspension compressor 6 needs to be started, the pressure in the air supply tank 1 is detected, and the pressure difference between the air supply tank 1 and the air suspension compressor 6 is determined. If the pressure difference is less than the fifth preset value, the two heating elements 2 are controlled to run simultaneously. After starting to heat the refrigerant in the air supply tank 1, it is also necessary to monitor the changes in the pressure difference in real time. If the rate of increase of the pressure difference is higher than the seventh preset value, only one heating element 2 is kept running. If the rate of increase of the pressure difference is lower than the seventh preset value, the two heating elements 2 are made to run simultaneously. When the pressure difference reaches the sixth preset value, it means that the pressure difference between the air supply tank 1 and the air suspension compressor 6 meets the requirements, and the air suspension compressor can be started and run.

[0055] After the air suspension compressor 6 is started up, if the pressure difference is greater than the seventh preset value, the two heating elements 2 are turned off at the same time.

[0056] When the air suspension compressor 6 starts and enters the operation stage, if the pressure difference is greater than the fifth preset value and less than the eighth preset value, where the eighth preset value is greater than the fifth preset value and less than the seventh preset value, one of the heating elements 2 is turned on to ensure the safe use of the heating element when the air suspension compressor is running.

[0057] After the air suspension compressor 6 enters the operation stage, the power element 4 continues to operate to transport refrigerant into the air supply tank 1. When the pressure in the air supply tank 1 is greater than the third preset value, the first valve 12 is controlled to switch to the cut-off state, and the second valve 14 is controlled to switch to the on state, so that the refrigerant transported by the power element 4 enters the evaporator 9.

[0058] On the other hand, an embodiment of the present invention further provides an air conditioner, comprising the air supply system for an air suspension compressor provided in any of the above-described embodiments. The air supply system for an air suspension compressor provided in any of the above-described embodiments can quickly establish a pressure differential between the air suspension compressor 6 and the air supply tank 1, facilitating the rapid startup of the air suspension compressor 6. Therefore, the air conditioner in this embodiment has the advantage of a fast startup speed. The derivation process for the beneficial effects of the air conditioner in the embodiment of the present invention is generally similar to the derivation process for the beneficial effects of the air supply system for an air suspension compressor described above, and therefore will not be repeated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
