Description

Technical Field

[0001] The invention relates to the technical field of air conditioning and refrigeration, and in particular to a multifunctional double-tank oil controller. Background Art

[0002] With the improvement of people's economic level, cars are becoming more and more popular. The popularity of cars has brought great convenience to people's travel, and air conditioning systems are basically installed in cars. The operating efficiency and service life of the air conditioning system depend on the chemical stability of the refrigeration system. Refrigerant and refrigeration oil are added to the refrigeration system. When the refrigeration system is contaminated by foreign matter such as dust, the foreign matter will change the stability of the refrigerant and refrigeration oil. Moreover, it will affect the relationship between pressure and temperature, reduce the working efficiency of the air conditioning system, and may cause internal corrosion and component wear of the air conditioning system. This requires irregular maintenance of the air conditioning system, and sometimes it is necessary to replace the refrigerant and refrigeration oil. When replacing, the refrigerant and refrigeration oil are discharged from the air conditioning system, and the refrigerant is recovered, and finally the refrigerant and refrigeration oil are added to the air conditioning system. The refrigerant and refrigeration oil can be added from the bypass hole of the air conditioning system compressor exhaust valve (high pressure valve) or the bypass hole of the air conditioning system compressor suction valve (low pressure valve). At present, there are also equipment for recycling and filling refrigerant and refrigeration oil in automobile air conditioning systems, but they are large in size and have high production costs.

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solution of the patent of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See attached Figure 1-5 , a multifunctional dual-tank oil controller, characterized by comprising:

[0027] The first tank body 100 and the second tank body 200 are arranged at intervals. The first tank body 100 and the second tank body 200 are both hollow structures with upper and lower openings. The first tank body 100 and the second tank body 200 are connected through a connecting pipe 300. Both ends of the connecting pipe 300 are threadedly connected to the first tank body 100 and the second tank body 200 at corresponding positions. A connecting valve 301 is provided on the connecting pipe 300. A first drainage pipe 201 connected to the second tank body 200 is threadedly fixed below the side wall of the second tank body 200 facing away from the first tank body 100.

[0028] The first connecting plate 400 and the second connecting plate 500 are arranged in parallel and spaced apart. The first connecting plate 400 is fixed to the top of the first tank body 100 and the second tank body 200 by bolts. A second drainage tube 401 connected to the first tank body 100 is threadedly fixed on the first connecting plate 400. A filter element 402 is fixed to the lower end of the second drainage tube 401 and is connected to it. In the present embodiment, the filter element 402 is a probe filter element with an accuracy of 1 μm. The third drainage tube 403 and the fourth drainage tube 404 connected to the second tank body 200 are also threadedly fixed on the first connecting plate 400. In the present embodiment, a one-way valve 4031 is fixed to the lower end of the third drainage tube 403 and is connected to it. The opening direction of the one-way valve 4031 is toward the inside of the second tank body 200. The second connecting plate 500 is fixed to the bottom of the first tank body 100 and the second tank body 200 by bolts.

[0029] Secondly, in this embodiment, the fifth drainage tube 101 connected to the first tank body 100 is threadedly fixed at the lower side wall facing away from the second tank body 200; the sixth drainage tube 405 connected to the first tank body 100 is threadedly fixed on the first connecting plate 400. A sealing cap 600 is threadedly connected to the third drainage tube 403, the fifth drainage tube 101 and the sixth drainage tube 405; the first drainage tube 201, the second drainage tube 401 and the fourth drainage tube 404 are all provided with a switch valve 700. The second drainage tube 401 is connected to a pressure gauge head 406.

[0030] In addition, in the present embodiment, an observation window 800 is provided on the side wall of the first tank body 100 and the second tank body 200 ; a sealing plate 900 with a transparent plate embedded in the middle is connected to the observation window 800 by bolts.

[0031] The working principle of the multifunctional dual-control oil control device in this embodiment is briefly described below:

[0032] When in use, the second drainage pipe 401 is connected to the high-pressure side joint of the air-conditioning system compressor, and the first drainage pipe 201 is connected to the low-pressure side joint of the air-conditioning system compressor. The switch valves 700 of the first drainage pipe 201 and the second drainage pipe 401 are opened respectively, and the connecting valve 301 is opened. The refrigerant and the refrigerating oil enter the filter element 402 through the second drainage pipe 401 and penetrate the filter element 402 into the first tank body 100. The filtered refrigerant enters the second tank body 200 through the connecting pipe 300, and then flows back to the air-conditioning system compressor through the first drainage pipe 201, completing the recovery of the refrigerant; a small part of the filtered refrigerating oil flows back to the air-conditioning system compressor with the refrigerant, and a large part is stored in the first tank body 100, which can be discharged to the outside through the fifth drainage pipe 101 to complete the recovery. When the refrigerant in the refrigerant and refrigeration oil mixture needs to be discharged, the connecting valve 301 is closed, and the sealing cap 600 on the sixth drainage pipe 405 is opened. At this time, the filtered refrigerant is discharged from the sixth drainage pipe 405 to the outside.

[0033] When refrigerant needs to be added, the connecting valve 301 is closed and refrigerant is added through the third drainage pipe 403. The one-way valve 4031 can prevent the refrigerant in the second tank body 200 from being lost when the refrigerant is added.

[0034] When refrigerant oil needs to be added, close the connecting valve 301, remove the fourth drainage pipe 404, and add refrigerant oil to the second tank body 200. It is easy to know here that when adding refrigerant oil, there must be no refrigerant in the second tank body 200, otherwise it will cause the loss of refrigerant.

[0035] Secondly, in actual use, if there is too much refrigerant oil, it will lead to poor refrigeration effect. In this embodiment, the fourth drainage pipe 404 can also be connected to the low-pressure side joint of the air-conditioning system compressor. The difference between it and the first drainage pipe 201 connected to the low-pressure side joint of the air-conditioning system compressor is that when the first drainage pipe 201 is connected to the low-pressure side joint of the air-conditioning system compressor, more refrigerant oil flows back into the air-conditioning system compressor; when the fourth drainage pipe 404 is connected to the low-pressure side joint of the air-conditioning system compressor, more refrigerant flows back into the air-conditioning system compressor. Through the above-mentioned different connection methods, the ratio of refrigerant oil and refrigerant can be adjusted to improve the refrigeration effect.

[0036] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the claims and their equivalents.
