[0052] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0053] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0054] In related technologies, air conditioning equipment in numerous commercial buildings is selected based on the total building load, choosing outdoor units of a specific capacity. Then, indoor units are selected to match the load of different independent spaces. Indoor units are generally selected in different forms according to the building's purpose to achieve optimal performance. However, many commercial buildings are put into use in phases, with the interior space later divided into different independent spaces according to different needs and uses. This necessitates designing matching air conditioning loads in later stages. Later-used building spaces may not have had their indoor unit types determined during the initial installation phase, or changes in building use may require replacement with different types of indoor units. In traditional air conditioning systems, adding or replacing indoor units later involves stopping the entire air conditioning system and extensive construction, severely impacting the operation of the initially installed indoor units and making the work extremely complex. Furthermore, installing all indoor units at once in the initial phase also results in high initial costs.

[0055] To address the complexity of installing or replacing indoor units in air conditioning systems, this invention provides a simplified procedure for retrofitting indoor units, enabling the installation or replacement of new indoor air conditioning units. The purpose of this embodiment is to resolve the issues of traditional air conditioning systems requiring system shutdown and complex installation processes for retrofitting indoor units.

[0056] Figure 1 This is a block diagram illustrating an air conditioning system according to an exemplary embodiment. Figure 1 As shown, the system includes: an outdoor unit 10; a first indoor unit 20; a second indoor unit 30a / 30b; a control module 31; a throttling mechanism 32; a shut-off valve 41 / 42; gas pipes 51 / 53; liquid pipes 52 / 54; and a communication circuit 60.

[0057] The outdoor unit 10 is installed on the outdoor side of the building space, and the first indoor unit 20 and the second indoor unit 30a / 30b are located on the indoor side of the building space.

[0058] In the initial construction phase of the air conditioning system installation, an outdoor unit 10 is selected to meet the air conditioning load requirements of the entire building space, and the outdoor unit 10 is installed on the outdoor side. The building space is divided into multiple areas, and a first indoor unit 20 is installed in each area. The first indoor unit 20 is used to regulate the indoor air, and its air conditioning load needs to be equal to the indoor building load of its corresponding area. However, in many commercial buildings, the indoor area is divided into several small spaces that are put into use in batches. For indoor areas that are not yet in use, it is impossible to determine the load of the first indoor unit or what type of first indoor unit should be installed. The indoor spaces that are put into use first will inevitably generate air conditioning demand first. To meet the air conditioning needs of the spaces that are put into use first, and to allow for the quick and easy installation of the first indoor unit in spaces that are put into use later, in this embodiment, a second indoor unit 30a / 30b is installed at the location where the first indoor unit may need to be installed. The outdoor unit 10 is connected to the second indoor unit via a communication line, a liquid pipe, and a gas pipe; the second indoor unit 30a / 30b is detachably connected to the liquid pipe and the gas pipe, wherein the second indoor unit 30a / 30b is a temporary unit and can be replaced by the first indoor unit 20.

[0059] The second indoor unit 30a / 30b includes a control module 31, shut-off valves 41 / 42, and a throttling mechanism 32;

[0060] The control module 31 is connected to the communication line, which is used to transmit signals and electrical energy.

[0061] In this embodiment, the control module 31 can communicate with the outdoor unit 10 or other first indoor unit 20 to receive or send relevant parameters.

[0062] The power required for the operation of the control module 31 is obtained through the communication line on the communication circuit 60, and the power is input from the outdoor unit 10. Therefore, no additional power supply is required when the second indoor unit 30a / 30b is installed, which simplifies the installation process of the second indoor unit 30a / 30b.

[0063] The throttling mechanism 32 is connected to the gas pipe 51 / 53 and the liquid pipe 52 / 54 via the shut-off valve 41 / 42, and is used to control the flow rate of refrigerant in the liquid pipe and the gas pipe.

[0064] In this embodiment, the air conditioning system primarily relies on a compressor and refrigerant for cooling and heating, with a certain proportion of refrigeration oil mixed in the refrigerant. The refrigerant flows in gas pipes 51 / 53 and liquid pipes 52 / 54, circulating between the outdoor unit and the indoor unit.

[0065] The control module 31 can also control the throttling mechanism 32 to increase, decrease, or cut off the flow rate, thereby adjusting the flow rate of the refrigerant flowing through the throttling mechanism 32 to prevent liquid and oil accumulation.

[0066] In this embodiment, a pair of shut-off valves 41 / 42 are installed at the pipe end of the second indoor unit 30a / 30b to facilitate the later installation of the indoor unit. Shut-off valve 41 is connected to the gas pipe 51 / 53 in the air conditioning system, and shut-off valve 42 is connected to the liquid pipe 52 / 54 in the air conditioning system. Shut-off valves 41 / 42 can be adjusted to a closed or open state. By opening shut-off valves 41 / 42, the second indoor unit 30a / 30b is connected to the air conditioning system.

[0067] Optionally, the throttling mechanism 32 can be any of the following: an electronic expansion valve; an electronic valve; or a capillary component.

[0068] In one possible embodiment, the throttling mechanism 32 is another adjustable flow throttling component, which has the function of completely shutting off or adjusting the bypass flow according to certain system parameters.

[0069] In one possible embodiment, the second indoor unit 30a / 30b can be installed in any location as needed, such as... Figure 1 As shown, 30a can be installed along the piping of the first indoor unit 20 so that an indoor unit can be added from this point later. 30b The second indoor unit is installed at the end of the air conditioning system, where there is a long blind pipe.

[0070] Optionally, in the scenario of disassembling the second indoor unit, the shut-off valve connected to the second indoor unit is in a closed state, and the connection between the second indoor unit and the shut-off valve and the communication line is disconnected.

[0071] Optionally, in the scenario where the first indoor unit is installed, the first indoor unit is connected to the shut-off valve and the communication line, and the shut-off valve is in the open state.

[0072] Optionally, in the scenario where the first indoor unit is installed, the first indoor unit between the shut-off valves is in a vacuum state.

[0073] Figure 2 This is a flowchart illustrating a method for installing a first indoor unit of an air conditioning system according to an exemplary embodiment. Figure 2 The method includes:

[0074] Step 201: Close the shut-off valve connected to the second indoor unit;

[0075] In this embodiment, the second indoor unit is a replacement for the first indoor unit when it is not installed. Therefore, if the first indoor unit needs to be installed at the location of the second indoor unit later, the second indoor unit must be removed and the first indoor unit installed at the location of the second indoor unit. To prevent refrigerant leakage in the gas pipes 51 / 53 and liquid pipes 52 / 54 of the air conditioning system after the shut-off valve is removed, the shut-off valve connected to the second indoor unit is closed.

[0076] Step 202: Disconnect the second indoor unit from the shut-off valve and the communication line, and disassemble the second indoor unit;

[0077] In this embodiment, after closing the shut-off valve, the second indoor unit can be safely disassembled. It is necessary to disconnect the connection between the second indoor unit and the shut-off valve, and disconnect the connection between the second indoor unit and the communication line, thus removing the second indoor unit from the communication circuit.

[0078] Step 203: Connect the first indoor unit to be installed to the shut-off valve and the communication line, and open the shut-off valve.

[0079] Optionally, after the step of connecting the first indoor unit to be installed to the shut-off valve and the communication line, the method further includes:

[0080] Vacuum is drawn from the shut-off valve for the first indoor unit to be installed.

[0081] In this embodiment, before connecting the first indoor unit to be installed to the gas pipe 51 / 53 and liquid pipe 52 / 54, in order to prevent other impurities (such as air and water) from entering the air pipe 51 / 53 and liquid pipe 52 / 54 of the air conditioning system, it is necessary to evacuate the first indoor unit to be installed from the shut-off valve, that is, to evacuate the pipeline through which the refrigerant flows in the first indoor unit to be installed, so as to ensure the normal operation of the air conditioning system.

[0082] Figure 3 This is a schematic diagram illustrating the installation of a first indoor unit according to an exemplary embodiment. For example... Figure 3As shown, 20a is the first indoor unit to be installed. This location was originally occupied by the second indoor unit 30b. The second indoor unit 30b was installed during the initial installation of the air conditioning system, and the first indoor unit 20a needs to be installed at the location of the second indoor unit 30b later. Simply close the shut-off valves 41 and 42, remove the second indoor unit 30b, and install the first indoor unit 20a. Vacuum the first indoor unit 20a from the shut-off valve, then open the shut-off valve to connect the first indoor unit 20a to the air conditioning system. As shown in the figure, when shut-off valves 41 and 42 are closed, the refrigerant exchange channels (gas pipes 51 / 53 and liquid pipes 52 / 54) between the other first indoor units 20 and the outdoor unit 10 in the air conditioning system remain unobstructed and unaffected by the closed shut-off valves, allowing for normal cooling or heating.

[0083] If the use of the indoor space changes and it is necessary to replace it with another type of first indoor unit, or if the air conditioning load of the indoor space changes significantly and it is necessary to replace the first indoor unit, the replacement work can be carried out by closing the shut-off valves 41 and 42. There is no need to recover the refrigerant of the entire system or a considerable distance of piping, which makes the replacement or addition of the first indoor unit easy and simple.

[0084] Figure 4 This is a flowchart illustrating an air conditioning system control method according to an exemplary embodiment, such as... Figure 4 As shown, the method includes:

[0085] Step 401: Receive control signals sent by the outdoor unit via the communication line;

[0086] In this embodiment, the reserved space for the later-installed first indoor unit in the entire air conditioning system can appear anywhere, such as at the end far from the first indoor unit, for example... Figure 1 The location of the second indoor unit 30b is shown. During operation, some refrigerant will inevitably accumulate in the piping from the main system line to the second indoor unit. Some refrigerant oil mixed with the flowing refrigerant will also accumulate in this section of the piping. Therefore, the problem of liquid accumulation and accumulated refrigerant oil in this section of the piping must be solved to allow the second indoor unit to be installed at any location, thus enabling quick and convenient installation of the first indoor unit later.

[0087] Step 402: Determine the operating status of the outdoor unit according to the control signal, and adjust the operating status of the throttling mechanism in the second indoor unit according to the operating status of the outdoor unit.

[0088] In this embodiment, the control module 31 in the second indoor unit 30a / 30b receives the control signal sent by the outdoor unit through the communication line, determines the operating status of the outdoor unit 10 according to the control signal, and selects how to adjust the operating status of the throttling mechanism 32 according to the operating status of the outdoor unit and the preset strategy.

[0089] This embodiment determines the operating status of the outdoor unit through the control signal and adjusts the operating status of the throttling mechanism, thereby avoiding liquid accumulation in the gas and liquid pipes of the air conditioning system and improving the stability and reliability of the air conditioning system.

[0090] Optionally, the operating status of the outdoor unit includes any of the following:

[0091] Oil return operation status;

[0092] Refrigeration operation status;

[0093] Heating operation status.

[0094] Optionally, adjusting the operating state of the throttling mechanism in the second indoor unit according to the operating state of the outdoor unit includes:

[0095] In response to the outdoor unit's operating state being oil return operation, the throttling mechanism is opened according to a preset opening ratio.

[0096] Generally, multi-split air conditioners need to undergo oil return operation after running for a certain period of time or after accumulating a certain amount of refrigerant oil. When the second indoor unit 30a / 30b receives the oil return operation signal from the outdoor unit 10, the second indoor unit 30a / 30b opens the throttling mechanism 32 according to the preset opening ratio, allowing a portion of the refrigerant flow to pass through the throttling mechanism 32. Under the action of the pressure difference of the outdoor unit, the refrigerant circulates along the pipeline to the outdoor unit. During this process, the refrigerant oil accumulated in the reserved pipeline section 53 / 54 will also mix with the refrigerant and be carried back to the outdoor unit. By responding to the oil return request of the outdoor unit 10, the second indoor unit 30a / 30b executes oil return control, and the refrigerant oil accumulated in the blind pipeline section 53 / 54 is also carried back to the outdoor unit 10, thus ensuring the operation of the outdoor unit 10.

[0097] Optionally, adjusting the operating state of the throttling mechanism in the second indoor unit according to the operating state of the outdoor unit includes:

[0098] In response to the outdoor unit being in cooling operation mode, the throttling mechanism is closed.

[0099] When adding refrigerant to the air conditioning system, the liquid line is filled to the brim. The liquid line remains full when the outdoor unit is running in cooling mode. Therefore, there is no continuous accumulation of excessive refrigerant in the liquid line during cooling mode. Similarly, the refrigerant in the gas line is in a low-pressure gaseous state during cooling mode, and the refrigerant flows from the second indoor unit towards the outdoor unit. Therefore, there is also no continuous accumulation of refrigerant. Thus, in cooling mode, it is only necessary to close the throttling mechanism 32.

[0100] However, even if there is no continuous refrigerant flow in pipes 53 and 54 in cooling mode, some refrigerant oil will remain in this section of pipe due to the outdoor unit operating in other modes. In order to prevent damage to the outdoor unit due to excessive refrigerant oil residue, the refrigerant oil in this pipe needs to be carried back to the outdoor unit.

[0101] Optionally, adjusting the operating state of the throttling mechanism in the second indoor unit according to the operating state of the outdoor unit includes:

[0102] In response to the outdoor unit being in heating mode, the throttling mechanism is opened according to a preset opening ratio; or,

[0103] In response to the outdoor unit's operating state being heating mode, a preset first time point and a preset second time point are obtained. At the first time point, the throttling mechanism is opened according to a preset opening ratio, and at the second time point, the throttling mechanism is closed; or,

[0104] In response to the outdoor unit being in heating mode, the operating parameters of the outdoor unit are acquired, a target opening ratio is obtained based on the operating parameters, and the throttling mechanism is opened according to the target opening ratio.

[0105] When the outdoor unit operates in heating mode, the high-temperature refrigerant in the blind pipe section 53 / 54 of the second indoor unit will slowly condense and accumulate in this section of the pipe due to heat dissipation to the environment. Refrigerant oil mixed in with the refrigerant will also accumulate in this section of the pipe. Therefore, the problem of liquid and refrigerant oil accumulation in the pipe section from the main pipe branch to the second indoor unit must be addressed during outdoor unit heating mode; otherwise, the outdoor unit will experience abnormal phenomena such as refrigerant and refrigerant oil shortages.

[0106] When the outdoor unit is in heating mode, to prevent excessive liquid refrigerant from accumulating in the gas pipe 53 due to heat dissipation into the environment, the second indoor unit controls the flow rate through the throttling mechanism 32 to ensure that the refrigerant in the gas pipe 53 flows slowly. The refrigerant-mixed refrigeration oil also flows with the refrigerant, so excessive liquid refrigerant will not accumulate in the pipe. The problem of liquid and oil accumulation in the gas pipe 53 is solved in heating mode, and the second indoor unit can be installed anywhere.

[0107] In addition, in heating mode, the second indoor unit can also use a timed opening of the throttling mechanism 32 to prevent liquid accumulation and refrigerant oil accumulation. The refrigerant in the gas pipe 53 slowly dissipates heat to the environment and condenses, so the throttling mechanism can be opened at certain intervals T1 to drain the liquid. After the draining time lasts for T2, the throttling mechanism 32 is closed, and the refrigerant oil accumulated there is also drained away along with the refrigerant.

[0108] In heating mode, liquid discharge control can also be implemented based on the outdoor unit's operating parameters. Specifically, the higher the outdoor unit's exhaust pressure and temperature, the more heat is dissipated from the gas pipe 53 to the environment, resulting in more refrigerant and mixed refrigerant oil condensing in the pipe. Therefore, the throttling mechanism 32 needs to operate at a larger flow rate to prevent liquid and oil accumulation. Conversely, the lower the exhaust pressure and temperature, the less heat is dissipated from the gas pipe 53 to the environment, resulting in less refrigerant and mixed refrigerant oil condensing in the pipe. Therefore, the throttling mechanism 32 can operate at a smaller flow rate to prevent liquid and oil accumulation.

[0109] Through the above heating and anti-liquid and anti-oil control measures, the gas pipe 53 will not continuously accumulate excessive liquid refrigerant, and the system operation is safe and reliable.

[0110] Optionally, the operating parameters of the outdoor unit include: exhaust pressure and / or exhaust temperature.
