Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] An air conditioner is a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. A general air conditioner is equipped with a frequency converter, which controls and adjusts the speed of the compressor so that the compressor can always be at the optimal speed state. This is a variable frequency air conditioner.

[0003] At present, the variable frequency air conditioner adjusts the operating frequency of the compressor according to the temperature of the space where the indoor unit is located, and realizes the variable frequency adjustment of the air conditioner, so as to adjust the temperature and humidity of the space where the indoor unit is located. However, the existing variable frequency air conditioner is limited to adjusting the operating frequency of the compressor, and the amount of refrigerant in its circulation is fixed.

[0004] The air conditioner has different refrigerant requirements at different ambient temperatures. Moreover, when the air conditioner is frequency-controlled, the compressor operates at different operating frequencies, and the air conditioner also has different refrigerant requirements. Therefore, the existing air conditioner adopts an operating scheme with a fixed refrigerant dosage, resulting in the refrigerant dosage of the air conditioner cycle not reaching the optimal value under many operating conditions and operating frequencies. The difference between the refrigerant dosage of the air conditioner cycle and the demand value is too large, which will increase the power consumption of the compressor operation and even cause adverse effects such as liquid shock to the compressor.

[0068] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0069] In the description of the present application, it should be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element. The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, it may be internal connectivity between two elements or an interactive relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0070] In the description of the present application, it should be understood that the terms "height", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. used in the present application to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0071] In the description of this application, it should be understood that the terms "first" and "second" are used in this application for descriptive purposes only, and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0072] In the present application, the air conditioner performs a refrigeration cycle or a heating cycle of the air conditioner through a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle and the heating cycle include a series of processes such as compression, condensation, expansion and evaporation, and provide cooling or heat to the indoor space through the heat absorption or heat release of the refrigerant to adjust the temperature of the indoor space.

[0073] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0074] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0075] The air conditioner of the present application includes an indoor unit of the air conditioner and an outdoor unit of the air conditioner, the outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit. The indoor unit of the air conditioner and the outdoor unit of the air conditioner can be a split design, such as a split air conditioner. The indoor unit of the air conditioner and the outdoor unit of the air conditioner can also be an integrated design, such as a window air conditioner.

[0076] Reference below Figure 1-Figure 12 The air conditioner 100 of the embodiment of the present application is described as an example of the present embodiment. The air conditioner 100 includes an air conditioner indoor unit 110 and an air conditioner outdoor unit 120. The air conditioner indoor unit 110 is provided with an indoor heat exchanger 3, and the air conditioner outdoor unit 120 is provided with an outdoor heat exchanger 4. It can be understood that the air conditioner 100 is only a split air conditioner as an illustrative example of the present embodiment, and the solution adopted in the present embodiment is not limited to the use of split air conditioners or integrated air conditioners.

[0077] The air conditioner 100 is provided with a refrigerant circulation circuit 1A, through which the refrigerant circulates. The refrigerant circulation circuit 1A of the present application includes a compressor 1, an expansion valve 2, an indoor heat exchanger 3, an outdoor heat exchanger 4 and a four-way valve 9, wherein the compressor 1 is used to compress and drive the refrigerant, and the compressor 1 is connected to the electric control box 1b, and the operating frequency is adjusted based on the variable frequency electric control board 10b inside the electric control box 1b. The exhaust pipe 1c and the return air pipe 1a of the compressor 1 are respectively connected to the four-way valve 9, and are connected to the indoor heat exchanger 3 and the outdoor heat exchanger 4 through the four-way valve 9.

[0078] In the refrigerant circulation circuit 1A of the air conditioner 100, the indoor heat exchanger 3 is used to perform heat exchange between the indoor airflow and the refrigerant transmitted to the indoor heat exchanger 3; the outdoor heat exchanger 4 is connected to the indoor heat exchanger 3, and is used to circulate the refrigerant between the indoor heat exchanger 3 and the outdoor heat exchanger 4, so as to perform heat exchange between the outdoor airflow and the refrigerant transmitted to the outdoor heat exchanger 4. The expansion valve 2 is arranged between the indoor heat exchanger 3 and the outdoor heat exchanger 4, so as to receive the refrigerant from the outdoor heat exchanger 4 when the air conditioner 100 operates in the cooling mode, or to receive the refrigerant from the indoor heat exchanger 3 when the air conditioner 100 operates in the heating mode, so as to adjust the fluid resistance of the refrigerant. After the compressor 1, the expansion valve 2, the indoor heat exchanger 3, the outdoor heat exchanger 4 and the four-way valve 9 are connected, the refrigerant circulation circuit 1A of the air conditioner 100 is formed. When the air conditioner 100 operates in cooling mode, the refrigerant circulates along the path of compressor 1 → outdoor heat exchanger 4 → expansion valve 2 → indoor heat exchanger 3 → compressor 1, and when the air conditioner 100 operates in heating mode, the refrigerant circulates along the path of compressor 1 → indoor heat exchanger 3 → expansion valve 2 → outdoor heat exchanger 4 → compressor 1.

[0079] It should be noted that the indoor heat exchanger 3 and the outdoor heat exchanger 4 can be used as a condenser or an evaporator. When the indoor heat exchanger 3 is used as a condenser, the air conditioner 100 is used as a heater in the heating mode, and when the indoor heat exchanger 3 is used as an evaporator, the air conditioner 100 is used as a cooler in the cooling mode.

[0080] like Figure 1-12 As shown, a refrigerant regulating device 2A is provided between the indoor heat exchanger 3 and the outdoor heat exchanger 4, the refrigerant regulating device 2A receives the refrigerant condensed by the indoor heat exchanger 3 or the outdoor heat exchanger 4, and delivers it to the expansion valve 2, and the refrigerant regulating device 2A has a first flow circuit, a second flow circuit, a first reversing circuit, and a second reversing circuit, wherein:

[0081] The first flow circuit enables the refrigerant regulating device 2A to receive the refrigerant condensed by the indoor heat exchanger 3 or the outdoor heat exchanger 4 and deliver it to the expansion valve 2;

[0082] The second flow circuit enables the refrigerant regulating device 2A to receive and store the refrigerant discharged through the expansion valve 2, and enables the compressor 1 to extract the refrigerant stored in the refrigerant regulating device 2A;

[0083] The first reversing circuit enables the refrigerant discharged from the outdoor heat exchanger 4 or the indoor heat exchanger 3 after condensation to enter the first flow circuit;

[0084] The second reversing circuit enables the refrigerant discharged from the expansion valve 2 to flow to the indoor heat exchanger 3 or the outdoor heat exchanger 4 for evaporation.

[0085] In some embodiments, Figure 2 , Figure 4-7 As shown, the refrigerant regulating device 2A includes a refrigerant regulator 5, wherein the refrigerant flowing out from the condenser outlet enters the refrigerant regulator 5 and then flows to the expansion valve 2, that is, when the air conditioner 100 operates in a cooling mode, the refrigerant condensed by the outdoor heat exchanger 4 enters the refrigerant regulator 5 and then flows to the expansion valve 2, and when the air conditioner 100 operates in a heating mode, the refrigerant condensed by the indoor heat exchanger 3 enters the refrigerant regulator 5 and then flows to the expansion valve 2.

[0086] As an example of this embodiment, the refrigerant regulator 5 includes a shell 5a, a delivery pipe 5b and an outlet pipe 5c, wherein:

[0087] The shell 5a is a cylindrical structure, and a storage chamber 5d is formed in the shell 5a. The storage chamber 5d is a closed chamber. The top of the shell 5a is provided with a first opening 50a and a second opening 51a communicating with the storage chamber 5d, and the bottom of the shell 5a is provided with a third opening 52a and a fourth opening 53a communicating with the storage chamber 5d. The outlet of the expansion valve 2 is connected to the second opening 51a at the top of the storage chamber 5d, so that the refrigerant flowing out of the expansion valve 2 can partially flow back to the storage chamber 5d for storage. Since the storage chamber 5d is used to store refrigerant, the storage chamber 5d itself or the outer side of the storage chamber 5d can have a heat preservation structure or a heat preservation layer.

[0088] The delivery pipe 5b enters the storage chamber 5d through the first opening 50a, extends to the bottom of the storage chamber 5d, and extends out of the storage chamber 5d from the fourth opening 53a of the storage chamber 5d, and the end of the delivery pipe 5b close to the first opening 50a is the inlet of the delivery pipe 5b, and the inlet of the delivery pipe 5b is connected to the outlet of the indoor heat exchanger 3 and the outlet of the outdoor heat exchanger 4 through the valve body, so that when the air conditioner 100 operates in the cooling mode, the refrigerant condensed by the outdoor heat exchanger 4 can flow to the inlet of the delivery pipe 5b, and when the air conditioner 100 operates in the heating mode, the refrigerant condensed by the indoor heat exchanger 3 can flow to the inlet of the delivery pipe 5b. The end of the delivery pipe 5b close to the fourth opening 53a is the outlet of the delivery pipe 5b, which is connected to the inlet of the expansion valve 2 to form a first flow loop.

[0089] One end of the air outlet pipe 5c extends into the storage chamber 5d through the third opening 52a and extends toward the top of the storage chamber 5d. The other end of the air outlet pipe 5c is connected to the return pipe 1a of the compressor 1 to form a second flow loop, so that the compressor 1 can extract the refrigerant stored in the storage chamber 5d. In addition, a distance H is left between the port of the air outlet pipe 5c toward the top of the storage chamber 5d and the inner wall of the top of the storage chamber 5d. 2 Moreover, the pipeline of the delivery pipe 5b in the storage chamber 5d is arranged around the outlet pipe 5c.

[0090] like Figure 2 , 3 As shown, during the operation of the air conditioner 100 in the cooling mode, the refrigerant flows from the outlet of the outdoor heat exchanger 4 to the inlet of the delivery pipe 5b, and passes through the storage chamber 5d through the delivery pipe 5b to the expansion valve 2. In this process, the refrigerant adjustment device 2A can perform the following actions according to the refrigerant usage of the air conditioner 100:

[0091] When the refrigerant consumption of the air conditioner 100 matches the operating frequency of the compressor 1 , the refrigerant regulating device 2A does not need to be operated, and all the refrigerant flowing out of the expansion valve 2 flows to the indoor heat exchanger 3 for evaporation and heat exchange, and returns to the compressor 1 .

[0092] When the air conditioner 100 uses too much refrigerant, the refrigerant regulating device 2A is activated, and part of the refrigerant flowing out of the expansion valve 2 flows back to the storage chamber 5d through the second opening 51a at the top of the storage chamber 5d for temporary storage, so as to reduce the amount of refrigerant running in the air conditioner 100. Part of it flows to the indoor heat exchanger 3 for evaporation and heat exchange, and returns to the compressor 1.

[0093] When the refrigerant consumption of the air conditioner 100 is insufficient, the refrigerant regulating device 2A is activated, and all the refrigerant flowing out through the expansion valve 2 flows to the indoor heat exchanger 3 for evaporation and heat exchange. In addition, the compressor 1 draws back the refrigerant temporarily stored in the storage chamber 5d to increase the refrigerant consumption in the air conditioner 100.

[0094] It is understandable that the air conditioner 100 can control the action execution of the refrigerant regulating device 2A during the refrigeration process of the air conditioner 100 through the valve body. In some embodiments, the refrigerant regulating device 2A includes a first valve 7 and a second valve 8, wherein the first valve 7 is arranged between the outlet of the air outlet pipe 5c and the return air pipe 1a of the compressor 1, and the second valve 8 is arranged between the outlet of the expansion valve 2 and the storage chamber 5d.

[0095] When the air conditioner 100 is in cooling mode, when the amount of refrigerant used by the air conditioner 100 matches the operating frequency of the compressor 1, the first valve 7 and the second valve 8 are closed, so that the refrigerant flowing out of the expansion valve 2 can all flow to the indoor heat exchanger 3 for evaporation and heat exchange;

[0096] When the amount of refrigerant used in the air conditioner 100 is too much, the first valve 7 is closed and the second valve 8 is opened, so that part of the refrigerant flowing out of the expansion valve 2 can flow back into the storage chamber 5d through the second opening 51a at the top of the storage chamber 5d for temporary storage, and part of the refrigerant flows to the indoor heat exchanger 3 for evaporation and heat exchange;

[0097] When the refrigerant consumption of the air conditioner 100 is insufficient, the first valve 7 is opened and the second valve 8 is closed, so that all the refrigerant flowing out of the expansion valve 2 flows to the indoor heat exchanger 3 for evaporation and heat exchange, and the compressor 1 withdraws the refrigerant temporarily stored in the storage chamber 5d.

[0098] The first valve 7 and the second valve 8 can be selected from solenoid valves and other valve bodies that can be controlled to perform actions through remote lines or wireless networks. Based on the settings of the first valve 7 and the second valve 8, the air conditioner 100 can enable the refrigerant regulating device 2A to store refrigerant or release the stored refrigerant, thereby adjusting the amount of refrigerant circulating in the refrigerant circulation loop 1A. It can be understood that in addition to setting up solenoid valves, the refrigerant regulating device 2A can also control the opening and closing of the connecting pipelines between the refrigerant regulating device 2A and the indoor heat exchanger 3, the outdoor heat exchanger 4, and the compressor 1 through electrical parts or electrical components such as sensors, photoelectric switches, and magnetic switches.

[0099] During the operation of the air conditioner 100 in the heating mode, Figure 4 As shown, the refrigerant flows from the outlet of the indoor heat exchanger 3 to the inlet of the delivery pipe 5 b , passes through the storage chamber 5 d through the delivery pipe 5 b , and flows to the expansion valve 2 .

[0100] It is understandable that, in the same air conditioner 100, the first valve 7 and the second valve 8 used in the cooling mode of the air conditioner 100 can also be used in the heating mode of the air conditioner 100 to control the action of the refrigerant regulating device 2A in the heating process of the air conditioner 100. In this way, when the air conditioner 100 is in the heating mode,

[0101] When the refrigerant consumption of the air conditioner 100 matches the operating frequency of the compressor 1, the first valve 7 and the second valve 8 are closed, so that the refrigerant flowing out of the expansion valve 2 can all flow to the outdoor heat exchanger 4 for evaporation and heat exchange;

[0102] When the amount of refrigerant used in the air conditioner 100 is too much, the first valve 7 is closed and the second valve 8 is opened, so that part of the refrigerant flowing out of the expansion valve 2 can flow back into the storage chamber 5d through the second opening 51a at the top of the storage chamber 5d for temporary storage, and part of the refrigerant flows to the outdoor heat exchanger 4 for evaporation and heat exchange;

[0103] When the refrigerant usage of the air conditioner 100 is insufficient, that is, when the second difference is greater than the sum of the set temperature and the set deviation temperature, the first valve 7 is opened and the second valve 8 is closed, so that all the refrigerant flowing out of the expansion valve 2 flows to the outdoor heat exchanger 4 for evaporation heat exchange, and the compressor 1 withdraws the refrigerant temporarily stored in the storage chamber 5d.

[0104] It should be noted that after the refrigerant flows out of the expansion valve 2, its temperature is generally lower than the temperature of the refrigerant at the outlet of the condenser. Therefore, after the refrigerant flows back to the storage chamber 5d through the expansion valve 2, the temperature of the refrigerant temporarily stored in the storage chamber 5d will be lower than the temperature of the refrigerant at the outlet of the condenser. Therefore, when the storage chamber 5d stores refrigerant, the refrigerant flowing into the delivery pipe 5b from the outlet of the condenser has a temperature higher than the temperature of the refrigerant in the storage chamber 5d. The refrigerant flowing in the delivery pipe 5b will exchange heat with the refrigerant stored in the storage chamber 5d, which will partially vaporize the refrigerant in the storage chamber 5d, reduce the refrigerant liquid level in the storage chamber 5d, and ensure that when the compressor 1 draws back the refrigerant in the storage chamber 5d, the refrigerant drawn back is all gaseous substances to prevent the compressor 1 from liquid hammering. On the other hand, the temperature of the refrigerant in the delivery pipe 5b is reduced, the supercooling degree of the air conditioner 100 is increased, thereby increasing the cooling capacity of the air conditioner 100 and further realizing the high-efficiency and energy-saving operation of the air conditioner 100.

[0105] It is understandable that the time and distance that the refrigerant flows in the storage chamber 5d will affect the degree of heat exchange between the refrigerant flowing in the delivery pipe 5b and the refrigerant in the storage chamber 5d. In some embodiments, the delivery pipe 5b is configured to rotate with the outlet pipe 5c as the spiral center and spirally arranged in the storage chamber 5d, so that the refrigerant flowing in the delivery pipe 5b can extend the time and distance that the refrigerant flows in the storage chamber 5d, so that the refrigerant flowing in the delivery pipe 5b can further heat exchange with the refrigerant in the storage chamber 5d, thereby improving the supercooling degree of the air conditioner 100.

[0106] After the refrigerant flows out of the expansion valve 2, it is a low-pressure and low-temperature liquid phase refrigerant. The liquid refrigerant falls into the storage chamber 5d at the top of the storage chamber 5d, and there is a risk that the liquid phase material falls into the air outlet pipe 5c, and the compressor 1 withdraws the refrigerant, causing a risk of liquid hammer. Therefore, in some embodiments, the storage chamber 5d is provided with a liquid inlet pipe 5e connected to the expansion valve 2, and the end of the liquid inlet pipe 5e toward the bottom of the storage chamber 5d is formed with a liquid inlet 50e, and the end of the air outlet pipe 5c toward the top of the storage chamber 5d is formed with an air outlet 50c, and the vertical distance H from the liquid inlet 50e to the top of the storage chamber 5d is 1 Greater than the vertical distance H from the air outlet 50c to the top of the storage chamber 5d 2 This ensures that when the liquid refrigerant enters the storage chamber 5d, the liquid refrigerant flows out from the liquid inlet 50e and is already below the air outlet 50c. The liquid refrigerant will fall directly into the storage chamber 5d under the action of gravity and cannot reversely enter the air outlet 50c, thereby effectively preventing the compressor 1 from extracting liquid refrigerant from the storage chamber 5d.

[0107] When the air conditioner 100 is capable of operating in cooling mode and heating mode, the input end of the refrigerant regulator 2A needs to switch the connection with the indoor heat exchanger 3 and the outdoor heat exchanger 4 to ensure that the condensed refrigerant enters the refrigerant regulator 5. Figure 2 , Figure 4 As shown, the refrigerant regulating device 2A also includes a reversing valve 6, which is connected to the refrigerant regulator 5, and when the air conditioner 100 operates in a cooling mode or when the air conditioner 100 operates in a heating mode, after the refrigerant flows out from the outlet of the condenser, it will first reach the reversing valve 6 and then flow into the refrigerant regulator 5, and after the refrigerant flows out of the refrigerant regulator 5, it will pass through the expansion valve 2 and reach the reversing valve 6 again, and be guided to flow to the inlet of the evaporator through the reversing valve 6.

[0108] Specifically, Figure 8 As shown, the reversing valve 6 includes a valve seat 6a, a flow guide pipe group 6b and a slider 6c, wherein a valve chamber 6d for refrigerant flow is formed in the valve seat 6a, and the valve chamber 6d is connected to the flow guide pipe group 6b, and the flow guide pipe group 6b has four pipe ports 60b connected to the valve chamber 6d, and the four pipe ports 60b are respectively connected to the indoor heat exchanger 3, the outdoor heat exchanger 4, the expansion valve 2, and the refrigerant regulating device 2A, so that the reversing valve 6 forms a valve body with four fluid ports. The refrigerant flows into the valve chamber 6d or flows out from the valve chamber 6d through the four pipe ports 60b, respectively, to realize the sequential operation between the indoor heat exchanger 3, the outdoor heat exchanger 4, the expansion valve 2, and the refrigerant regulating device 2A.

[0109] A slider 6c is provided in the valve chamber 6d. The slider 6c itself does not have the function of fluid passage, and the refrigerant cannot penetrate the slider 6c. Therefore, the slider 6c can be arranged in the valve chamber 6d to separate the valve chamber 6d, and the slider 6c is configured to be able to slide back and forth in the valve chamber 6d. The shape and contour of the slider 6c can be diverse, and the slider 6c slides back and forth in the valve chamber 6d. Since the slider 6c itself does not have the function of fluid passage, the space in the valve chamber 6d will be separated by the slider 6c, so that the space in the valve chamber 6d forms two areas that are separated from each other and do not interfere with each other. At the same time, the multiple pipe openings 60b of the guide tube group 6b are configured to be able to connect the aforementioned two areas respectively, so that the communication path between the pipe opening 60b and the valve chamber 6d is separated by the slider 6c, and the valve chamber 6d is connected to two of the pipe openings 60b to form a first reversing circuit, and the remaining two pipe openings 60b are connected to each other to form a second reversing circuit that is not connected to the first reversing circuit, thereby guiding the refrigerant to pass through the valve chamber 6d along a specified direction, wherein,

[0110] The first reversing circuit is used to make the high-pressure liquid refrigerant discharged from the condenser outlet flow to the first flow circuit and enter the refrigerant regulator 5;

[0111] The second reversing circuit is used to receive the low-temperature and low-pressure refrigerant flowing out of the expansion valve 2, and make the low-temperature and low-pressure refrigerant flow to the evaporator, that is, the indoor heat exchanger 3 when the air conditioner 100 operates in the cooling mode or the outdoor heat exchanger 4 when the air conditioner 100 operates in the heating mode.

[0112] By setting the first reversing circuit and the second reversing circuit, the reversing valve 6 can switch the refrigerant flow path when the air conditioner 100 is operating in the cooling mode and when the air conditioner 100 is operating in the heating mode, thereby ensuring that the high-pressure liquid refrigerant discharged from the condenser flows to the refrigerant regulator 5, while the low-temperature and low-pressure refrigerant flowing out of the expansion valve 2 flows to the evaporator.

[0113] It is understandable that the flow guide pipe group 6b includes a plurality of independent pipes, which are respectively connected to the indoor heat exchanger 3, the outdoor heat exchanger 4, the expansion valve 2, and the refrigerant regulating device 2A. Figure 8 As shown, the guide tube group 6b includes a first guide tube 61b, a second guide tube 62b, a third guide tube 63b and a fourth guide tube 64b, and the first guide tube 61b, the second guide tube 62b, the third guide tube 63b and the fourth guide tube 64b are respectively connected to the four pipeline openings 60b in a one-to-one correspondence, wherein,

[0114] The first flow conduit 61b is connected to the outdoor heat exchanger 4 so that the valve chamber 6d is connected to the outdoor heat exchanger 4; the second flow conduit 62b is connected to the expansion valve 2 so that the valve chamber 6d is connected to the expansion valve 2; the third flow conduit 63b is connected to the indoor heat exchanger 3 so that the valve chamber 6d is connected to the indoor heat exchanger 3; the fourth flow conduit 64b is connected to the refrigerant regulator 5 so that the valve chamber 6d is connected to the refrigerant regulator 5.

[0115] like Figure 8 As shown, the first flow guide pipe 61b, the second flow guide pipe 62b, and the third flow guide pipe 63b are arranged on the same side of the valve chamber 6d, and the first flow guide pipe 61b, the second flow guide pipe 62b, and the third flow guide pipe 63b are arranged in sequence from the right side of the valve chamber 6d to the left side of the valve chamber 6d, and the fourth flow guide pipe 64b is arranged on the other side of the valve chamber 6d. In this way, when the size of the slider 6c is able to cover the pipe openings of the two flow guide pipes, the slider 6c can achieve a fast switching of the connection between the flow guide pipe group 6b and the indoor heat exchanger 3, the outdoor heat exchanger 4, the expansion valve 2, and the refrigerant regulating device 2A during the reciprocating movement of the slider 6c in the valve chamber 6d.

[0116] Specifically, a connecting cavity 60c is provided in the slider 6c, and the connecting cavity 60c is separated from the valve chamber 6d, and the connecting cavity 60c and the valve chamber 6d are not connected to each other.

[0117] like Fig.11As shown, when the slider 6c slides to the leftmost side of the valve chamber 6d, the slider 6c blocks the connection between the second guide tube 62b, the third guide tube 63b and the valve chamber 6d, so that the first guide tube 61b, the fourth guide tube 64b and the valve chamber 6d are connected, so that the first guide tube 61b, the fourth guide tube 64b and the valve chamber 6d form a first reversing circuit, and the second guide tube 62b, the third guide tube 63b and the connecting cavity 60c of the slider 6c are connected to form a second reversing circuit;

[0118] like Fig. 9 As shown, when the slider 6c slides to the rightmost side of the valve chamber 6d, the slider 6c blocks the connection between the first and second flow guide tubes 61b, 62b and the valve chamber 6d, so that the third and fourth flow guide tubes 63b, 64b are connected to the valve chamber 6d, and the first and fourth flow guide tubes 61b, 64b and the valve chamber 6d form a first reversing circuit, and the first and second flow guide tubes 61b, 62b are connected to the connecting cavity 60c of the slider 6c, forming a second reversing circuit.

[0119] In order to facilitate the sliding block 6c to slide back and forth between the left side and the right side of the valve chamber 6d, in some embodiments, as shown in FIG. Figure 8-12 As shown, the reversing valve 6 also includes a right guide pipe 6e and a left guide pipe 6f, wherein:

[0120] The right flow guide pipe 6e is connected to the first flow guide pipe and the valve seat 6a, so that the first flow guide pipe 61b is connected to the right side of the valve chamber 6d through the right flow guide pipe 6e, and the left flow guide pipe 6f is connected to the third flow guide pipe and the valve seat 6a, so that the third flow guide pipe 63b is connected to the left side of the valve chamber 6d through the left flow guide pipe 6f; the left and right sides of the slider 6c respectively have a fitting surface 61c for fitting with the left and right inner walls of the valve seat 6a, and the connection between the left flow guide pipe 6f and the valve seat 6a and the connection between the right flow guide pipe 6e and the valve seat 6a are located in the positive projection area of ​​the fitting surface 61c on the inner wall of the valve seat 6a.

[0121] When the air conditioner 100 operates in cooling mode, Figure 2 , Fig.11 , Fig.12As shown, the refrigerant flows from the outdoor heat exchanger 4 to the first flow guide pipe 61b. At this time, if the slider 6c is already on the left side of the valve chamber 6d, the refrigerant can flow directly from the first flow guide pipe 61b to the fourth flow guide pipe 64b, and then flow into the refrigerant regulator 5 to form a first reversing loop, and the second flow guide pipe 62b and the third flow guide pipe 63b are connected to the connecting cavity 60c to form a second reversing loop. If the slider 6c is on the right side of the valve chamber 6d, the first flow guide pipe 61b is blocked, because the refrigerant flows from the outdoor heat exchanger 4 to the first flow guide pipe 61b, the pipeline resistance of the first flow guide pipe 61b will increase, so that the refrigerant flows from the right flow guide pipe 6e to the right side of the valve chamber 6d, and then pushes the slider 6c to move to the left side of the valve chamber 6d, so that the first flow guide pipe 61b is connected with the fourth flow guide pipe 64b.

[0122] It should be noted that when the air conditioner 100 is in cooling mode, after the refrigerant flows out from the outlet of the outdoor heat exchanger 4, it will first flow to the first guide tube 61b. At this time, if the slider 6c is on the right side of the valve chamber 6d, since the refrigerant cannot penetrate the slider 6c, the slider 6c will block the pipe opening 60b of the first guide tube 61b, so that the refrigerant flows to the right side of the valve chamber 6d through the right guide tube 6e, thereby pushing the slider 6c to slide to the left side of the valve chamber 6d. Although the first guide tube 61b and the second guide tube 62b may be connected to the connecting cavity 60c during the sliding process of the slider 6c, since the second guide tube 62b is connected to the outlet of the expansion valve 2, the refrigerant cannot flow back through the expansion valve 2, so the first guide tube 61b and the second guide tube 62b will not form a flow loop. When the slider 6c moves to the left side of the valve chamber 6d, the refrigerant can flow directly from the first guide tube 61b to the fourth guide tube 64b, and then flow into the refrigerant regulator 5 to form a first reversing circuit, and the second guide tube 62b and the third guide tube 63b are connected to the connecting cavity 60c to form a second reversing circuit.

[0123] When the air conditioner 100 operates in the heating mode, Figure 4 , Fig. 9 , Fig.10 As shown, the refrigerant flows from the indoor heat exchanger 3 to the third flow guide pipe 63b. At this time, if the slider 6c is already on the right side of the valve chamber 6d, the refrigerant can flow directly from the third flow guide pipe 63b to the fourth flow guide pipe 64b, and then flow into the refrigerant regulator 5 to form a first reversing loop, and the first flow guide pipe 61b and the second flow guide pipe 62b are connected to the connecting cavity 60c to form a second reversing loop. If the slider 6c is on the left side of the valve chamber 6d, the third flow guide pipe 63b is blocked, and the pipeline resistance of the third flow guide pipe 63b will increase, so that the refrigerant flows from the left flow guide pipe 6f to the left side of the valve chamber 6d, and then pushes the slider 6c to move to the right side of the valve chamber 6d, so that the third flow guide pipe 63b is connected with the fourth flow guide pipe 64b.

[0124] It should be noted that when the air conditioner 100 is in heating mode, after the refrigerant flows out from the outlet of the indoor heat exchanger 3, it will first flow to the third flow guide pipe 63b. At this time, if the slider 6c is on the left side of the valve chamber 6d, since the refrigerant cannot penetrate the slider 6c, the slider 6c will block the pipe opening 60b of the third flow guide pipe 63b, so that the refrigerant flows to the left side of the valve chamber 6d through the left flow guide pipe 6f, thereby pushing the slider 6c to slide to the right side of the valve chamber 6d. Although the third flow guide pipe 63b and the second flow guide pipe 62b may be connected to the connecting cavity 60c during the sliding process of the slider 6c, the same as when the air conditioner 100 is in cooling mode, since the second flow guide pipe 62b is connected to the outlet of the expansion valve 2, the refrigerant cannot flow back through the expansion valve 2, so the third flow guide pipe 63b and the second flow guide pipe 62b will not form a flow loop. When the slider 6c moves to the right side of the valve chamber 6d, the refrigerant can flow directly from the third flow guide pipe 63b to the fourth flow guide pipe 64b, and then flow into the refrigerant regulator 5 to form a first reversing circuit. The first flow guide pipe 61b and the second flow guide pipe 62b are connected to the connecting cavity 60c to form a second reversing circuit.

[0125] Based on the aforementioned air conditioner 100, this embodiment describes the working process of the air conditioner 100 as follows:

[0126] When the air conditioner 100 operates in the cooling mode, the compressor 1 discharges the high-temperature and high-pressure gaseous refrigerant through the four-way valve 9, reaches the outdoor heat exchanger 4 for condensation and heat release, and condenses into liquid refrigerant in the outdoor heat exchanger 4. The condensed refrigerant condenses into liquid refrigerant at the outlet of the outdoor heat exchanger 4, and the high-pressure liquid refrigerant flows out of the condenser outflow pipe, reaches the first guide pipe 61b of the reversing valve 6, passes through the right guide pipe 6e, reaches the right side of the valve chamber 6d, and the high-pressure refrigerant pushes the slider 6c to the left. At this time, the first guide pipe 61b is connected with the fourth guide pipe 64b to form a first reversing circuit, and the second guide pipe 62b is connected with the third guide pipe 63b to form a second reversing circuit.

[0127] After passing through the first guide pipe 61b and the fourth guide pipe 64b, the liquid refrigerant reaches the delivery pipe 5b of the refrigerant regulator 5, exchanges heat with the refrigerant in the storage chamber 5d, and reaches the expansion valve 2 for throttling, becoming a low-temperature and low-pressure liquid refrigerant. After the low-temperature and low-pressure liquid refrigerant reaches the second reversing circuit of the reversing valve 6, it flows out to the indoor heat exchanger 3 for evaporation. The evaporated refrigerant is a low-temperature gaseous refrigerant, and finally returns to the compressor 1 through the four-way valve 9. The low-temperature and low-pressure liquid refrigerant reaches the second valve 8 on the other side. Based on the first difference, the first valve 7 and the second valve 8 are selectively opened or closed to adjust the amount of refrigerant circulating in the air conditioner 100.

[0128] When the air conditioner 100 operates in the heating mode, the compressor 1 discharges the high-temperature and high-pressure gaseous refrigerant through the four-way valve 9, reaches the indoor heat exchanger 3 for condensation and heat release, and condenses into liquid refrigerant in the indoor heat exchanger 3. The condensed refrigerant condenses into liquid refrigerant at the outlet of the indoor heat exchanger 3.

[0129] The liquid refrigerant reaches the third flow conduit 63b of the reversing valve 6, passes through the left flow conduit 6f, and reaches the left side of the valve chamber 6d, and the high-pressure refrigerant pushes the slider 6c to the right. At this time, the third flow conduit 63b is connected with the fourth flow conduit 64b to form a first reversing loop, and the second flow conduit 62b is connected with the first flow conduit 61b to form a second reversing loop.

[0130] The liquid refrigerant passes through the first reversing circuit and reaches the delivery pipe 5b of the refrigerant regulator 5. After exchanging heat with the refrigerant in the storage chamber 5d, it reaches the expansion valve 2 for throttling and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant reaches the second reversing circuit of the reversing valve 6, and then evaporates after reaching the outdoor heat exchanger 4. The evaporated refrigerant is a low-temperature and low-pressure gaseous refrigerant, and finally returns to the compressor 1 after passing through the four-way valve 9.

[0131] In summary, the air conditioner 100 provided in the embodiment of the present application is equipped with a refrigerant regulating device 2A in the refrigerant circulation loop 1A, and the refrigerant running in the air conditioner 100 is stored or the refrigerant stored in the refrigerant regulating device 2A is released back to the refrigerant circulation loop 1A by controlling the opening and closing of the refrigerant regulating device 2A, and when the air conditioner 100 is running in the heating mode, the refrigerant usage of the air conditioner 100 in the current running state is reduced or increased, so as to realize the refrigerant usage of the air conditioner 100, so that the air conditioner 100 can be operated in different operating conditions and different compressor 1 operation modes. Under different operating frequencies and operating modes, the amount of refrigerant circulating in the air conditioner 100 is always optimal, which matches the variable frequency operation of the compressor 1, ensuring that the real-time energy efficiency of the air conditioner 100 reaches the highest efficiency. Moreover, the refrigerant regulating device 2A receives the refrigerant condensed by the indoor heat exchanger 3 or the outdoor heat exchanger 4. No matter whether the air conditioner 100 is operating in the cooling mode or the heating mode, the refrigerant entering the refrigerant regulating device 2A flows out from the condenser outlet, which can effectively ensure the supercooling of the refrigerant before entering the expansion valve 2, thereby improving the cooling capacity and heating capacity of the air conditioner 100.

[0132] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
