Description

Technical Field

[0001] The utility model relates to air conditioning equipment, in particular to an oil-gas separator of an air conditioning system with auxiliary heating and gasification. Background Art

[0002] With the continuous development of air-conditioning technology, the efficiency and performance of air-conditioning systems have received more and more attention. Existing air-conditioning systems usually include compressors, condensers, evaporators and throttling devices, among which the oil-gas separator is an indispensable component of the air-conditioning system. The main function of the oil-gas separator is to separate the oil from the gas in the oil-containing gas discharged by the compressor to prevent the oil from entering the condenser and evaporator, affecting the heat exchange efficiency and operating stability of the air-conditioning system.

[0003] The prior art oil-gas separator has the following defects:

[0004] 1. In a low temperature environment, the liquid refrigerant has a low temperature, insufficient heat, and a slow gasification rate, and cannot be quickly converted into gas. This will result in a large amount of liquid refrigerant inside the oil-gas separator.

[0005] 2. When the liquid refrigerant cannot be completely vaporized in the oil-gas separator, the unvaporized liquid refrigerant will enter the compressor along with the return oil. The compressor is designed to compress gaseous refrigerant, and the return of liquid refrigerant will cause liquid to mix into the compressor.

[0006] 3. Liquid hammer phenomenon: After the liquid refrigerant enters the compressor, the high-speed moving parts in the compressor will produce a strong impact with the liquid refrigerant. This impact is called liquid hammer phenomenon. Liquid hammer will cause serious damage to the internal parts of the compressor, such as the piston, valve, etc., and eventually lead to compressor failure or even failure.

[0007] Traditional oil-gas separators usually rely on mechanical separation methods such as gravity separation, inertial separation or filtration separation. These methods are less efficient in low-temperature environments and it is difficult to ensure efficient oil-gas separation. Under low-temperature conditions, due to the slow gasification rate of liquid refrigerant, traditional mechanical separation methods cannot effectively solve the problem of liquid refrigerant mixing into the compressor, which in turn affects the performance and life of the entire air-conditioning system. Therefore, it is necessary to make further improvements to it. Utility Model Content

[0008] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide an oil-gas separator for an air-conditioning system with a simple structure and easy use, and an auxiliary heating and gasification function. The oil-gas separator is heated by an electromagnetic heating device to quickly gasify the liquid refrigerant in the separation chamber, thereby improving the oil-gas separation efficiency and the refrigerant recovery efficiency, preventing the liquid refrigerant from entering the compressor, avoiding the occurrence of liquid hammer, and improving the overall performance and operating stability of the air-conditioning system.

[0009] The purpose of the utility model is achieved in the following way: an oil-gas separator for an air-conditioning system with auxiliary heating and gasification, which includes an outer shell, the interior of the outer shell is hollow to form a separation chamber, the top of the outer shell is provided with a mixed fluid inlet and a gaseous refrigerant outlet, the bottom of the outer shell is provided with an oil return port, the outer shell is made of ferromagnetic material, the surface of the outer shell is coated with a thermal insulation layer, an electromagnetic heating coil is sleeved outside the thermal insulation layer, the electromagnetic heating coil is connected to an electromagnetic heating controller, the electromagnetic heating controller drives the electromagnetic heating coil to work, heats the outer shell to cause its temperature to rise, and accelerates the gasification speed of the liquid refrigerant in the separation chamber.

[0010] Furthermore: the shell is cylindrical, and the electromagnetic heating coil is installed on its outer cylindrical surface.

[0011] Furthermore: the electromagnetic heating coil is installed on its outer cylindrical surface in a spirally wound shape.

[0012] Furthermore: the thermal insulation layer is thermal insulation cotton.

[0013] The beneficial effects of the utility model are:

[0014] The structure is simple, the production cost is low, and the market competitiveness is improved.

[0015] The utility model heats the outer shell of the oil-gas separator by arranging an electromagnetic heating coil on the outer shell surface, and the electromagnetic heating controller controls the electromagnetic heating coil to work. In this way, the temperature in the oil-gas separation chamber is increased, thereby accelerating the gasification speed of the liquid refrigerant. Compared with the traditional mechanical separation method, the utility model significantly improves the efficiency of oil-gas separation, especially in a low-temperature environment, and can maintain efficient separation performance.

[0016] 3. Since the oil-gas separator of the utility model can quickly gasify the liquid refrigerant, the liquid refrigerant is prevented from being retained in the oil-gas separation chamber. In this way, the liquid refrigerant will not enter the compressor along with the return oil, thereby effectively preventing the liquid hammer phenomenon caused by the liquid refrigerant entering the compressor, and protecting the normal operation and service life of the compressor.

[0017] 4. By increasing the gasification speed of liquid refrigerant and the oil-gas separation efficiency, the utility model reduces the phenomenon of liquid refrigerant reflux in the compressor and reduces the risk of equipment failure caused by liquid hammer. This not only extends the service life of the compressor, but also significantly improves the operating stability and reliability of the air conditioning system.

[0018] 5. The utility model is particularly suitable for air conditioning systems in low temperature environments. The traditional oil-gas separator has low separation efficiency under low temperature conditions, which makes it difficult for the liquid refrigerant to be completely gasified. The utility model heats the oil-gas separator through an electromagnetic heating device, ensuring that the liquid refrigerant can still be efficiently separated in a low temperature environment, thereby improving the operating performance of the air conditioning system under low temperature conditions.

[0019] 6. By optimizing the oil-gas separation process, the utility model reduces the power consumption of the compressor caused by the refrigeration of liquid refrigerant, and improves the overall energy efficiency of the refrigeration system. At the same time, by quickly gasifying the liquid refrigerant, the waste and discharge of the refrigerant are reduced, which is more environmentally friendly.

[0020] 7. The oil-gas separator of the utility model has a reasonable structural design, and the installation and operation of components such as the housing, electromagnetic heating coil and electromagnetic heating controller are relatively simple. It is easy to integrate and implement in the existing air-conditioning system, and has high practicality and operability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings. An air conditioning system oil-gas separator with auxiliary heating and gasification includes a shell 1, the interior of the shell 1 is hollow to form a separation chamber 2, the top of the shell 1 is provided with a mixed fluid inlet 3 and a gaseous refrigerant outlet 4, and the bottom of the shell 1 is provided with an oil return port 5, the shell 1 is made of ferromagnetic material, the surface of the shell 1 is coated with a thermal insulation layer 7, an electromagnetic heating coil 8 is sleeved outside the thermal insulation layer 7, the electromagnetic heating coil 8 is connected to an electromagnetic heating controller 9, and the electromagnetic heating controller 9 drives the electromagnetic heating coil 8 to work, heats the shell 1 to generate a temperature rise, and accelerates the gasification speed of the liquid refrigerant in the separation chamber 2.

[0025] In one embodiment, the housing 1 is cylindrical, and the electromagnetic heating coil 8 is installed on its outer cylindrical surface.

[0026] In one embodiment, the electromagnetic heating coil 8 is installed on the outer cylindrical surface in a spirally wound shape.

[0027] In one embodiment, the thermal insulation layer 7 is thermal insulation cotton.

[0028] Working principle: The utility model relates to an air-conditioning system oil-gas separator with auxiliary heating and gasification function, which aims to improve the gasification speed of liquid refrigerant and the oil-gas separation efficiency, especially to maintain high efficiency in low temperature environment and prevent liquid refrigerant from entering the compressor to cause liquid hammer. The shell of the oil-gas separator in this case is made of ferromagnetic material, and the interior is hollow to form an oil-gas separation chamber 2. The top of the shell is provided with a mixed fluid inlet 3 and a gaseous refrigerant outlet 4, and the bottom is provided with an oil return port 5.

[0029] The surface of the housing 1 is coated with a heat-insulating layer to reduce heat loss and ensure the heating efficiency of the electromagnetic heating coil, and also to prevent the housing temperature from decreasing due to the ambient temperature in low temperature conditions.

[0030] The electromagnetic heating coil is spirally wound and installed outside the insulation layer 7 to heat the shell. The electromagnetic heating coil 8 is controlled to control its working state according to the ambient temperature and the target temperature, and the heating power and time are adjusted to stabilize the temperature inside the shell at the optimal vaporization temperature.

[0031] When the air conditioning system is working, a mixed fluid containing oil and liquid and gaseous refrigerants enters the oil-gas separation chamber 2 through the mixed fluid inlet 3. In the separation chamber, the mixed fluid is initially separated from the oil and gas under the mechanical separation effects of gravity, inertia, etc.

[0032] When the ambient temperature and the temperature inside the shell are lower than the set value, the electromagnetic heating controller 9 starts to drive the electromagnetic heating coil 8 to work. The electromagnetic heating coil heats the shell 1 through electromagnetic induction, and the shell 1 heats up rapidly, transferring heat to the mixed fluid in the oil-gas separation chamber 2.

[0033] Due to the temperature rise of the shell 1, the liquid refrigerant in the separation chamber 2 absorbs heat and the gasification speed is significantly accelerated. The rapidly gasified refrigerant becomes gaseous and is discharged from the separation chamber through the gaseous refrigerant outlet 4 to enter the next link of the air conditioning system. Among them, the electromagnetic heating controller 9 can adjust the electromagnetic heating coil accordingly through frequency conversion control, time control, power control, etc., so that its heating amount is balanced with the heat required by the system to ensure the stability of the system operation.

[0034] Through auxiliary heating, the oil-gas separator can still maintain efficient oil-gas separation performance in low temperature environment. The liquid refrigerant is quickly vaporized, thus preventing the liquid refrigerant from entering the compressor along with the return oil.

[0035] Since the liquid refrigerant is quickly gasified in the separation chamber, it is prevented from entering the compressor and causing liquid hammer, thereby protecting the normal operation of the compressor and extending the service life of the compressor.

[0036] Compared with traditional technologies, this system accelerates the gasification speed of liquid refrigerant and improves the oil-gas separation efficiency through auxiliary heating, which is particularly suitable for low-temperature environments. It effectively prevents liquid refrigerant from entering the compressor, avoids the occurrence of liquid hammer, and ensures the stable operation of the air-conditioning system. It improves the operating stability and reliability of the air-conditioning system and extends the service life of the equipment. In addition, it reduces the power consumption of the compressor caused by the reflux of liquid refrigerant, improves the overall energy efficiency of the system, and has the advantages of energy saving and environmental protection.

[0037] In summary, the utility model realizes efficient oil and gas separation in a low temperature environment, improves the overall performance of the air-conditioning system, and has significant technical advantages and broad application prospects.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
