Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning intake temperature regulating device and a regulating method. Background Art

[0002] Currently, conventional rolling rotor compressors primarily consist of a compressor body and a liquid reservoir. The compressor body primarily consists of a pump assembly, a motor assembly, and a housing, with the liquid reservoir located on one side of the compressor body. The reservoir's inlet pipe connects to the system piping, while its outlet pipe connects to the pump body within the compressor body. The high-temperature, high-pressure refrigerant gas generated by the pump body enters the system piping through the compressor's outlet. After being converted to low-temperature, low-pressure gas through condensation and evaporation in the system piping, it enters the reservoir through its inlet pipe and enters the pump body through its outlet pipe, thus completing the cyclical operation of the compressor and system piping.

[0003] During actual air conditioning system operation, insufficient suction superheat is very likely to occur in low-frequency, light-duty applications, or in low-temperature environments after a long period of quiescence and start-up, resulting in a large amount of liquid refrigerant when the compressor inhales. In high-frequency, heavy-duty applications, the high internal temperature of the compressor transfers this heat to the low-temperature liquid reservoir, causing the refrigerant in the reservoir to overheat, resulting in excessively high suction temperatures and ineffective overheating. In recent years, compressors have been developing towards broadband operation, with lower low frequencies and higher high frequencies. Therefore, it is urgent to address both insufficient and excessive suction superheat in low-frequency, light-duty applications, low-temperature quiescent start-up, and high-frequency, heavy-duty applications. Summary of the Invention

[0004] The present invention provides an air-conditioning intake air temperature adjustment device and adjustment method, so as to solve the problem in the prior art that the intake air superheat is insufficient in low-frequency scenarios or the intake air superheat is too high in high-frequency scenarios.

[0005] According to one aspect of the present invention, an air-conditioning intake temperature regulating device is provided, which includes: a compressor, the compressor having a first intake port, a first outlet port, a compression chamber and a first heat exchange port, the first intake port, the first outlet port and the first heat exchange port being connected to the compression chamber respectively; a liquid reservoir, the liquid reservoir having a second intake port, a second outlet port, a cavity and a second heat exchange port, the second intake port, the second outlet port and the second heat exchange port being connected to the cavity respectively, and the second outlet port being connected to the first intake port; an isolating element, arranged between the compressor and the liquid reservoir, the isolating element having an isolating chamber, the isolating chamber being connected to the first heat exchange port and the second heat exchange port respectively, the isolating chamber being selectively connected to the first heat exchange port or the second heat exchange port, and the isolating chamber being capable of storing refrigerant.

[0006] Furthermore, the air conditioning intake temperature control device also includes: a connecting pipe, which is connected to the first heat exchange port, the second heat exchange port and the isolation chamber respectively; a control valve, which is arranged on the connecting pipe, and the control valve is used to control the isolation chamber to selectively connect with the first heat exchange port or the second heat exchange port.

[0007] Furthermore, the air-conditioning intake temperature regulating device further includes: a mounting bracket fixed on the outer side wall of the compressor, the mounting bracket being connected to the liquid reservoir and the isolating member respectively to fix the compressor, the liquid reservoir and the isolating member to each other.

[0008] Furthermore, the mounting bracket specifically includes a fixing frame and a pressure plate. The fixing frame is fixed on the outer wall of the compressor. The pressure plate is arranged around the outer periphery of the liquid reservoir, and both ends of the pressure plate are fixedly connected to the fixing frame respectively. The isolation member is located between the liquid reservoir and the fixing frame.

[0009] Furthermore, the fixing bracket has a first connecting section, a second connecting section and a third connecting section connected in sequence along the circumference of the liquid reservoir, the middle part of the second connecting section protrudes toward the compressor, and a limiting groove is formed on the side of the second connecting section facing the liquid reservoir, and the outer surface of the side of the isolating member close to the fixing bracket is adapted to the shape of the fixing bracket.

[0010] Furthermore, a side of the isolating member close to the liquid reservoir is in contact with an outer side wall of the liquid reservoir, and a surface of the isolating member in contact with the outer side wall of the liquid reservoir is adapted to an outer surface of the liquid reservoir.

[0011] Furthermore, the first air outlet and the first heat exchange port are both located at the top of the compressor, and the first air intake port is located at the bottom of the compressor; the second air intake port and the second heat exchange port are both located at the top of the liquid reservoir, and the second air outlet is located at the bottom of the liquid reservoir.

[0012] Furthermore, the length of the isolating member along the axis of the liquid reservoir is L, and the length of the liquid reservoir along the axis is L1, wherein 0.5*L1≤L≤L1.

[0013] Furthermore, a line connecting the center of the transverse section of the liquid reservoir and the center of the compressor is a reference line, and the isolation members are symmetrically arranged with respect to the reference line.

[0014] According to another aspect of the present invention, a method for adjusting the air intake temperature of an air conditioner is provided. The method for adjusting the air intake temperature of an air conditioner uses the above-mentioned device, comprising:

With this arrangement, in low-frequency scenarios, that is, when the intake superheat is low, the first heat exchange port can be connected to the isolation cavity, allowing the high-temperature refrigerant in the compressor to flow into the isolation cavity, and heat is transferred to the liquid reservoir through the isolator, thereby increasing the refrigerant temperature in the liquid reservoir and increasing the intake superheat. This reduces the risk of the compressor intake containing a large amount of liquid refrigerant due to insufficient intake superheat in low-frequency scenarios. In high-frequency scenarios, that is, when the suction superheat is high, the second heat exchange port is connected to the isolation cavity, so that the low-temperature refrigerant in the liquid reservoir flows into the isolation cavity, so as to isolate the high-temperature compressor from the heat transfer to the low-temperature liquid reservoir through the low-temperature refrigerant in the isolation cavity, thereby avoiding the high temperature of the compressor under high-frequency and heavy working conditions, and its high heat is transferred to the low-temperature liquid reservoir, causing the compressor suction temperature to be too high and resulting in invalid overheating. The technical solution provided by this application can take into account the problems of insufficient or excessive suction superheat in different application scenarios such as low-frequency and light working conditions, low-temperature static start-up, and high-frequency and heavy working conditions, thereby effectively optimizing and improving the degree of compressor suction superheat, increasing the suction superheat in application scenarios such as low-frequency and light working conditions and low-temperature static start-up, reducing the suction superheat in application scenarios such as high-frequency and heavy working conditions, ensuring the volumetric efficiency of the pump body in the compressor, thereby improving the energy efficiency level of the compressor and the air-conditioning system, and reducing its reliability risk.

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. 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.

[0036] like Figure 1 and Figure 2As shown, the present application provides an air-conditioning intake temperature control device, specifically comprising: a compressor 10, a liquid accumulator 20, and an isolator 30. The compressor 10 has a first intake port 11, a first outlet 12, a compression chamber 13, and a first heat exchange port 14. The first intake port 11, the first outlet 12, and the first heat exchange port 14 are respectively connected to the compression chamber 13. The liquid accumulator 20 has a second intake port 21, a second outlet 22, a cavity 23, and a second heat exchange port 24. The second intake port 21, the second outlet 22, and the second heat exchange port 24 are respectively connected to the cavity 23. The second outlet 22 is connected to the first intake port 11. The first outlet 12 is used to communicate with the condenser, and the second intake port 21 is used to communicate with the evaporator. The isolation member 30 is arranged between the compressor 10 and the liquid accumulator 20. The isolation member 30 has an isolation cavity, which is respectively connected to the first heat exchange port 14 and the second heat exchange port 24. The isolation cavity can be selectively connected to the first heat exchange port 14 or the second heat exchange port 24, and the refrigerant can be stored in the isolation cavity.

[0037] The isolator 30 can be spaced apart from the compressor 10 and the liquid reservoir 20, or the isolator 30 can be spaced apart from the compressor 10 and the liquid reservoir 20 can be placed in close contact with the isolator 30. In the present application, the isolator 30 is spaced apart from the compressor 10 and in close contact with the liquid reservoir 20. In this way, the isolator 30 can not only isolate the compressor 10 but also conduct heat to the liquid reservoir 20.

[0038] Applying the technical solution of the present invention, the air-conditioning intake air temperature control device includes a compressor 10, a liquid reservoir 20, and an isolator 30. A first heat exchange port 14 is provided on the compressor 10, and a second heat exchange port 24 is provided on the liquid reservoir 20. The isolator 30 is used to connect the first heat exchange port 14 and the second heat exchange port 24, respectively, so that the isolation cavity can selectively communicate with the first heat exchange port 14 or the second heat exchange port 24. With this arrangement, in low-frequency scenarios, that is, when the intake air superheat is low, the first heat exchange port 14 can be connected to the isolation cavity, allowing the high-temperature refrigerant in the compressor 10 to flow into the isolation cavity and transfer heat to the liquid reservoir 20 through the isolator 30, thereby increasing the refrigerant temperature in the liquid reservoir 20 and increasing the intake air superheat. This reduces the risk of the compressor 10 inhaling a large amount of liquid refrigerant due to insufficient intake air superheat in low-frequency scenarios. In a high-frequency scenario, that is, when the suction superheat is high, the second heat exchange port 24 is connected to the isolation cavity, so that the low-temperature refrigerant in the liquid reservoir 20 flows into the isolation cavity, and the high-temperature compressor 10 is isolated by the isolation member 30 to transfer heat to the low-temperature liquid reservoir 20, thereby avoiding the high temperature of the compressor 10 being too high under high-frequency heavy working conditions, and its high heat being transferred to the low-temperature liquid reservoir 20, causing the suction temperature of the compressor 10 to be too high and resulting in ineffective overheating.

[0039] Through the technical solution provided in this application, it is possible to take into account the problems of insufficient or excessive suction superheat in different application scenarios such as low-frequency light working conditions, low-temperature static starting, and high-frequency heavy working conditions, thereby effectively optimizing and improving the suction superheat of the compressor, increasing the suction superheat in application scenarios such as low-frequency light working conditions and low-temperature static starting, and reducing the suction superheat in application scenarios such as high-frequency heavy working conditions, ensuring the volumetric efficiency of the pump body in the compressor, thereby improving the energy efficiency level of the compressor and air-conditioning system, and reducing its reliability risk.

[0040] In this application, the spacer 30 is a thin-walled structure made of steel materials such as SPCC / SPHC / SPHD, with a thickness of 1.5 to 3.5 mm. The above materials and dimensions can ensure the structural strength of the spacer 30.

[0041] In the present application, the air conditioning intake temperature control device further includes a connecting pipe 40 and a control valve 50. The connecting pipe 40 is connected to the first heat exchange port 14, the second heat exchange port 24, and the isolation chamber, respectively. The control valve 50 is disposed on the connecting pipe 40 and can control the isolation chamber to selectively connect to the first heat exchange port 14 or the second heat exchange port 24. This structure facilitates connection between the first heat exchange port 14, the second heat exchange port 24, and the isolation chamber, and facilitates opening and closing control of the connecting pipe 40.

[0042] like Figure 3 As shown, specifically, in the present application, the connecting pipe 40 includes a first pipe, a second pipe and a third pipe, one ends of the first pipe, the second pipe and the third pipe are connected to each other, the other end of the first pipe is connected to the first heat exchange port 14, the second pipe is located between the compressor 10 and the accumulator 20, the other end of the second pipe is connected to the isolation member 30, and the other end of the third pipe is connected to the second heat exchange port 24, and the control valve 50 is provided at the connection between the first pipe, the second pipe and the third pipe to control the communication between the first pipe and the second pipe, or the communication between the third pipe and the second pipe.

[0043] The device may also be equipped with a controller and a temperature sensor. The temperature sensor can detect the actual operating temperature of the compressor. The controller can determine whether the suction superheat is low, normal, or excessive based on the actual operating temperature of the compressor, the saturation temperature corresponding to the evaporation pressure, and the preset range of suction superheat. If the suction superheat is low, the control valve 50 is controlled to connect the first pipe and the second pipe. If the suction superheat is high, the control valve 50 is controlled to connect the third pipe and the second pipe. This structure allows real-time monitoring of the system and timely adjustment of the operation of the control valve 50.

[0044] like Figure 2 and Figure 4As shown, the air conditioning intake temperature control device also includes a mounting bracket 60, which is fixed to the outer wall of the compressor 10. The mounting bracket 60 is respectively connected to the liquid reservoir 20 and the isolation member 30 to fix the compressor 10, the liquid reservoir 20, and the isolation member 30 to each other. By providing the mounting bracket 60, the liquid reservoir 20 and the isolation member 30 can be easily installed and fixed, and the stability of the liquid reservoir 20 and the isolation member 30 can be improved, thereby preventing the two from vibrating and emitting noise during operation. By uniformly fixing the liquid reservoir 20 and the isolation member 30 through the mounting bracket 60, the structure can be simplified and the installation efficiency can be improved.

[0045] Among them, the mounting bracket 60 specifically includes a fixing frame 61 and a pressure plate 62. The fixing frame 61 is fixed on the outer wall of the compressor 10, and the pressure plate 62 is arranged around the outer periphery of the liquid reservoir 20, and the two ends of the pressure plate 62 are respectively fixedly connected to the fixing frame 61. The isolating member 30 is located between the liquid reservoir 20 and the fixing frame 61. The fixing frame 61 and the compressor 10 can be fixed by welding or fasteners, and the pressure plate 62 and the fixing frame 61 can be connected by fasteners to facilitate their disassembly and assembly. Through the above structure, the liquid reservoir 20 and the isolating member 30 can be fixed together, which is convenient for installation, and the isolating member 30 can also be tightly fitted with the liquid reservoir 20 to ensure the heat conduction effect of the two.

[0046] like Figures 4 to 7 As shown, the fixing frame 61 has a first connecting section 611, a second connecting section 612 and a third connecting section 613 connected in sequence along the circumference of the liquid reservoir 20. The middle portion of the second connecting section 612 protrudes toward the compressor 10. A limiting groove is formed on the side of the second connecting section 612 facing the liquid reservoir 20. The outer surface of the side of the isolating member 30 close to the fixing frame 61 is adapted to the shape of the fixing frame 61. Among them, the isolating member 30 includes a first side surface 31 and a second side surface 32 arranged opposite to each other. The first side surface 31 is arranged toward the compressor 10, and the second side surface 32 is arranged toward the liquid reservoir 20. The shape of the first side surface 31 is designed to be adapted to the shape of the fixing frame 61, so that the isolating member 30 can fit tightly with the fixing frame 61, achieving a good fixing effect. In addition, the limiting groove in the middle portion of the second connecting section 612 is adapted to the protrusion on the first side surface 31 to limit each other, thereby further improving the connection stability between the isolating member 30 and the fixing frame 61.

[0047] In other embodiments of the present application, the fixing bracket 61 may also be designed as other structures as long as it can be conveniently fixedly connected to the compressor 10 and the pressure plate 62 .

[0048] In the present application, the first connecting section 611 and the third connecting section 613 are both arc-shaped structures to increase the contact area with the isolation member 30 and improve the fixing effect.

[0049] The side of the isolator 30 that is close to the liquid reservoir 20 is in contact with the outer wall of the liquid reservoir 20, and the surface of the isolator 30 that is in contact with the outer wall of the liquid reservoir 20 is adapted to the outer surface of the liquid reservoir 20, that is, the second side surface 32 is adapted to the outer surface of the liquid reservoir 20. In this embodiment, the second side surface 32 is specifically a curved surface. This allows the isolator 30 to better fit the liquid reservoir 20, thereby improving the heat conduction effect between the two. In other embodiments of the present application, the isolator 30 can also be designed as an entire arc and arranged around the outer periphery of the liquid reservoir 20.

[0050] Specifically, the shape of the isolation cavity is adapted to the outer shape of the isolation member 30 to increase the volume of the isolation cavity as much as possible.

[0051] In the present application, the length of the isolator 30 along the axis of the accumulator 20 is L, and the length of the accumulator 20 along the axis is L1, where 0.5*L1≤L≤L1. By setting the length of the isolator 30 within this range, the isolator 30 can ensure the isolation effect on the compressor 10, increase the contact area between the isolator 30 and the accumulator 20, and improve the heat exchange effect between the two.

[0052] The first air outlet 12 and the first heat exchange port 14 are both located at the top of the compressor 10, and the first air intake port 11 is located at the bottom of the compressor 10. The second air intake port 21 and the second heat exchange port 24 are both located at the top of the liquid reservoir 20, and the second air outlet 22 is located at the bottom of the liquid reservoir 20. In the present application, the first heat exchange port 14 is located at the top of the compressor 10, and the second heat exchange port 24 is located at the top of the liquid reservoir 20, so that the refrigerant in the compressor 10 and the liquid reservoir 20 can easily enter the isolation chamber.

[0053] like Figure 1 As shown, the compressor 10 of the present application is a conventional rolling rotor compressor, internally provided with a motor assembly 70 and a pump assembly 80. The pump assembly 80 forms the bottom portion of the compressor 10. The motor assembly 70 is disposed in the middle of the compression chamber 13, dividing the compression chamber 13 into an upper motor chamber and a lower motor chamber. The pump assembly 80 forms the lower motor chamber. The first air outlet 12 and the first heat exchange port 14 are both connected to the upper motor chamber, thereby preventing obstruction to the exhaust of the compressor 10.

[0054] like Figure 2 As shown, in this application, the line connecting the center of the transverse section of the liquid reservoir 20 and the center of the compressor 10 is used as a reference line, and the spacers 30 are arranged symmetrically about the reference line. This arrangement allows the spacers 30 to uniformly control the heat of the liquid reservoir 20, and the symmetrical structure is relatively simple, making it easy to manufacture and install.

[0055] Another embodiment of the present application provides an air conditioning intake temperature adjustment method, which uses the adjustment device provided in the above embodiment. The method specifically includes:

[0056] Get the operating temperature T1 inside the compressor, get the saturation temperature corresponding to the evaporation pressure as T2, and the preset range of the suction superheat is [T01, T02];

[0057] When T1-T2<T01, the isolation cavity is communicated with the first heat exchange port; when T1-T2>T02, the isolation cavity is communicated with the second heat exchange port.

[0058] During startup of the air conditioning system, through the control method provided herein, when the suction superheat is below a preset lower threshold value T01, the isolation cavity of the isolation member 30 communicates with the high-temperature compression chamber 13, placing the isolation member 30 in a high-temperature state and transferring heat more quickly to the low-temperature reservoir 20, thereby increasing the temperature within the reservoir 20 and the suction superheat. This reduces the risk of the compressor carrying a large amount of liquid refrigerant during suction due to insufficient suction superheat, which can occur in low-frequency, light operating conditions or when the system is started after a long period of quiescence in a low-temperature environment. When the suction superheat is above its preset upper threshold value T02, the isolation cavity of the isolation member 30 communicates with the cavity of the low-temperature reservoir 20, placing the isolation member 30 in a low-temperature state, isolating the high-temperature compressor 10 from transferring heat to the low-temperature reservoir 20. This prevents the high heat from being transferred to the low-temperature reservoir 20 due to excessively high compressor 10 temperature under high-frequency, heavy operating conditions, which could cause the compressor 10 suction temperature to be too high and result in ineffective overheating. Through the technical solution provided by this application, it is possible to take into account the problem of insufficient or excessive suction superheat in different application scenarios such as low-frequency light working conditions, low-temperature static start-up and high-frequency heavy working conditions, thereby effectively optimizing and improving the suction superheat of the compressor 10, increasing the suction superheat in application scenarios such as low-frequency light working conditions and low-temperature static start-up, and reducing the suction superheat in application scenarios such as high-frequency heavy working conditions, ensuring the volumetric efficiency of the compressor pump body, thereby improving the energy efficiency level of the compressor and the air-conditioning system and reducing its reliability risk. At the same time, by reducing the suction superheat in application scenarios such as high-frequency working conditions, the exhaust temperature of the compressor 10 when it is running under heavy load can be controlled. On the other hand, when it is under high-frequency heavy load, the isolation member 30 is connected to the liquid reservoir 20 and is in a low-temperature state, which can effectively absorb the heat emitted by the compressor 10, reduce the temperature of the compressor 10 cavity, and further reduce the exhaust temperature, thereby reducing the operational reliability risk of the compressor due to high temperature to a certain extent.
