Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner, a volume calculation method for a volume container, a calculation device, an electronic device, and a computer-readable storage medium. Background Technology

[0002] In related technologies, in the air conditioning system of an air conditioner, the compressor is connected to the heat exchanger through a one-way valve, which can be used to prevent refrigerant from flowing back to the compressor.

[0003] Currently, during the transportation of air conditioners, the pipe between the one-way valve and the shut-off valve is in a closed state, which can form a blind pipe section. The refrigerant in the blind pipe section is easily affected by high temperature during transportation. The temperature of the refrigerant rises, the molecular movement speed of the refrigerant accelerates, and the increased gas pressure in the blind pipe section exceeds the pressure bearing capacity, resulting in pipe rupture, damage to the air conditioner, and thus increasing the maintenance cost of the air conditioner. Summary of the Invention

[0004] The present invention provides a method for calculating the volume of an air conditioner and a volume container, a calculation device, an electronic device, and a computer-readable storage medium that can solve the problem of air conditioner pipes bursting due to excessively high ambient temperature causing the pressure in the refrigerant pipes to exceed the pressure bearing capacity during transportation.

[0005] An air conditioner provided by an embodiment of the present invention includes a compressor, a one-way valve, a condenser, and a volume container. The compressor is connected to the condenser through the one-way valve, and the volume container is connected to the refrigerant pipe between the one-way valve and the condenser and is used to contain the refrigerant between the one-way valve and the condenser.

[0006] In this way, by adding a volumetric container in the refrigerant pipe between the one-way valve and the heat exchanger, the refrigerant in the pipe can enter the volumetric container when it is at a high temperature. This reduces or avoids pipe bursts to some extent, thus preventing damage to the air conditioner during transportation and reducing maintenance costs.

[0007] In some embodiments, the air conditioner includes a four-way valve, the one-way valve is connected to the condenser through the four-way valve, the volume container connects the refrigerant line between the one-way valve and the four-way valve and / or the volume container connects the refrigerant line between the four-way valve and the condenser.

[0008] Thus, by installing a volumetric container in the refrigerant pipeline between the one-way valve and the four-way valve and / or in the refrigerant pipeline between the four-way valve and the condenser, the refrigerant in the pipeline can enter the volumetric container when it is at a high temperature, which can reduce or avoid the occurrence of pipe bursts to a certain extent, thereby avoiding damage to the air conditioner during transportation and reducing the maintenance cost of the air conditioner to a certain extent.

[0009] In some embodiments, the air conditioner includes at least one of the volume containers, the total volume of which is determined based on the mass and density of the refrigerant between the one-way valve and the condenser, and the actual volume of the refrigerant piping between the one-way valve and the condenser.

[0010] In this way, by setting the number of volumetric containers to multiple, and ensuring that the volume of multiple volumetric containers is determined by the mass and density of the refrigerant between the one-way valve and the condenser, as well as the actual volume of the refrigerant pipe between the one-way valve and the condenser, it is possible to avoid pipe bursts caused by excessive refrigerant pressure due to insufficient volume, and to reduce the fluctuation and pressure changes of the refrigerant in the refrigerant pipe, thereby ensuring that the air conditioner can continuously provide stable cooling or heating effects.

[0011] In some embodiments, the volumetric container includes at least one of a muffler, an oil separator, and a filter.

[0012] Thus, by selecting at least one of the following as a volume container: a silencer, an oil separator, and a filter, it is possible to prevent refrigerant pipe bursts while providing additional functions to the air conditioner, thereby improving resource utilization and reducing costs.

[0013] In some embodiments, the volume of the volumetric container is determined by the cooling capacity range of the air conditioner.

[0014] In this way, by determining the cooling capacity range of the air conditioner, the corresponding refrigerant quantity of the air conditioner can be obtained. Then, by looking up the table based on the refrigerant quantity, the volume of the container can be determined without a complicated volume calculation process, thereby improving the speed of determining the volume of the container.

[0015] The volume calculation method for a volumetric container according to embodiments of the present invention is used in an air conditioner. The air conditioner includes a compressor, a one-way valve, a condenser, and a volumetric container. The compressor is connected to the condenser through the one-way valve. The volumetric container is connected to a refrigerant pipe between the one-way valve and the condenser and is used to contain the refrigerant between the one-way valve and the condenser. The volume calculation method includes obtaining the mass and density of the refrigerant in the refrigerant pipe between the one-way valve and the condenser, as well as the actual volume of the refrigerant pipe; determining the minimum theoretical volume of the refrigerant pipe based on the mass and density of the refrigerant in the refrigerant pipe; and determining the volume of the volumetric container based on the difference between the minimum theoretical volume and the actual volume.

[0016] Thus, by obtaining the mass and density of the refrigerant in the refrigerant pipe between the one-way valve and the condenser, as well as the actual volume of the refrigerant pipe, the volume of the volumetric container can be determined. This avoids the situation where the volumetric container is too small, resulting in insufficient pressure on the volumetric container and causing the pressure in the refrigerant pipe to exceed the pressure bearing capacity, thus leading to pipe bursting. It also avoids the situation where the volumetric container is too large, resulting in insufficient refrigerant flowing into the condenser for heat exchange, thereby reducing the heating or cooling effect.

[0017] In some embodiments, obtaining the density of the refrigerant in the refrigerant pipeline between the one-way valve and the condenser includes obtaining the highest ambient temperature of the refrigerant in the refrigerant pipeline and the withstand pressure at the weakest pressure-resistant part of the refrigerant pipeline; and determining the density of the refrigerant in the refrigerant pipeline based on a preset mapping relationship of temperature, pressure and density, the highest ambient temperature and the withstand pressure.

[0018] Thus, by substituting the highest ambient temperature of the refrigerant in the refrigerant pipeline and the pressure resistance at the weakest point in the refrigerant pipeline into the preset mapping relationship of temperature, pressure and density, the density of the refrigerant in the refrigerant pipeline can be determined, thereby accurately obtaining the density of the refrigerant and improving the accuracy of determining the volume of the container.

[0019] In some embodiments, the preset mapping relationship includes a state equation for the change of refrigerant density with ambient temperature and withstand pressure, or a table showing the change of refrigerant density with ambient temperature and withstand pressure.

[0020] Thus, by substituting the highest ambient temperature of the refrigerant in the refrigerant pipeline and the pressure resistance at the weakest point in the refrigerant pipeline into a preset state equation or by querying a preset table, the efficiency of determining the refrigerant density can be improved.

[0021] The volume calculation method for a volumetric container according to embodiments of the present invention is used in an air conditioner. The air conditioner includes a compressor, a one-way valve, a condenser, and a volumetric container. The compressor is connected to the condenser through the one-way valve. The volumetric container is connected to a refrigerant pipe between the one-way valve and the condenser and is used to contain the refrigerant between the one-way valve and the condenser. The volume calculation method includes obtaining a preset cooling capacity range of the air conditioner; and determining the volume of the volumetric container according to a preset mapping relationship between the cooling capacity range and the volume and the preset cooling capacity range.

[0022] Thus, by determining the volume of the volume container based on the preset mapping relationship between the air conditioner's preset cooling capacity range and its volume, the efficiency of determining the volume of the volume container can be improved.

[0023] The computing device of the present invention includes a processor and a memory; the memory stores a computer program, which, when executed by the processor, implements the steps of the volume calculation method for the volume container described in any of the above embodiments.

[0024] The electronic device according to the embodiments of the present invention includes the computing device described in the above embodiments.

[0025] The computer-readable storage medium of the present invention stores a computer program thereon, which, when executed by a processor, implements the steps of the volume calculation method for the volume container described in any of the above embodiments.

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

[0037] Please see Figure 1 An air conditioner 100 provided by an embodiment of the present invention includes a compressor 10, a one-way valve 20, a condenser 30 and a volume container 40. The compressor 10 is connected to the condenser 30 through the one-way valve 20. The volume container 40 is connected to the refrigerant pipe 50 between the one-way valve 20 and the condenser 30 and is used to contain the refrigerant between the one-way valve 20 and the condenser 30.

[0038] Thus, by adding a volume container 40 to the refrigerant pipe 50 between the one-way valve 20 and the heat exchanger, the refrigerant in the refrigerant pipe 50 can enter the volume container 40 when it is at a high temperature. This reduces or avoids the possibility of the refrigerant pipe 50 bursting, thereby preventing damage to the air conditioner 100 during transportation and reducing the maintenance cost of the air conditioner 100 to some extent.

[0039] Air conditioner 100 is a device used to directly supply treated air to an enclosed room, space, or area. Air conditioner 100 can provide cooling, heating, dehumidification, and air purification functions to the indoor environment. Air conditioner 100 completes the cooling and heating processes through changes in the phase state, temperature, and pressure of the refrigerant within the air conditioner 100.

[0040] However, during transportation, the refrigerant pipe 50 between the one-way valve 20 and the shut-off valve is in a closed state. Furthermore, the air conditioner 100 is susceptible to high temperatures during transportation, causing the refrigerant temperature to rise and the refrigerant molecules to move faster. This can lead to the increased pressure within the refrigerant pipe 50 exceeding its pressure-bearing capacity, resulting in pipe rupture and damage to the air conditioner 100. Therefore, it is necessary to increase the volume of the refrigerant pipe 50 to prevent the pressure within it from exceeding its pressure-bearing capacity.

[0041] Specifically, the air conditioner 100 includes a compressor 10, a one-way valve 20, a condenser 30, and a volumetric container 40. The compressor 10 serves as the power core of the air conditioner 100, primarily responsible for circulating and compressing the refrigerant to complete the air conditioning cycle of cooling or heating. The compressor 10 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, increasing its temperature and pressure to create conditions for condensation at a higher temperature. Then, the high-temperature, high-pressure gaseous refrigerant is delivered to other components of the air conditioner 100 to complete the cooling or heating cycle.

[0042] The one-way valve 20, also known as a check valve, has the ability to conduct in one direction and stop in the reverse direction. In the air conditioner 100, the compressor 10 is connected to the condenser 30 through the one-way valve 20, thus the one-way valve 20 can control the forward and reverse flow of the refrigerant, ensuring that the refrigerant can only flow in a certain specified direction, that is, from the compressor 10 to the condenser 30. For example, when the compressor 10 is stopped, the one-way valve 20 can prevent a large amount of high-temperature, high-pressure gaseous refrigerant inside the refrigerant pipe 50 from flowing back into the compressor 10.

[0043] The condenser 30 dissipates heat and cools the high-temperature, high-pressure gaseous refrigerant delivered by the compressor 10, causing it to condense into a liquid, high-pressure refrigerant. Depending on the operating mode of the air conditioner 100, the heat generated by condensation is distributed to different locations. For example, when the air conditioner 100 is in cooling mode, the condenser 30 dissipates the heat generated by the condensed high-pressure, high-temperature gaseous refrigerant to the outdoor environment to complete the cooling cycle; when the air conditioner 100 is in heating mode, the condenser 30 dissipates the heat generated by the condensed high-pressure, high-temperature gaseous refrigerant into the indoor room to complete the heating cycle.

[0044] The volumetric container 40 is connected to the refrigerant pipeline 50 between the one-way valve 20 and the condenser 30, allowing refrigerant in the refrigerant pipeline 50 to enter the volumetric container 40. This allows the volumetric container 40 to hold excess refrigerant in the refrigerant pipeline 50, thereby reducing the pressure in the refrigerant pipeline 50. The volumetric container 40 may include, but is not limited to, at least one of a muffler, an oil separator, and a filter.

[0045] It should be noted that silencers are devices that reduce airflow noise in ventilation and air conditioning systems by utilizing principles such as sound absorption, reflection, and interference. Based on different silencing principles, they can be classified into resistive, reactive, resonant, and composite types. Their main function is to reduce noise pollution in air conditioning systems and improve indoor comfort. By reducing airflow noise, silencers help create a quieter and more pleasant indoor environment.

[0046] An oil separator, installed after the compressor 10, separates the lubricating oil from the compressor 10's exhaust and, through its built-in control device, returns the lubricating oil to the compressor 10's oil collection tank. This prevents the compressor 10 from running out of oil during continuous system operation and also prevents lubricating oil from accumulating in other components of the air conditioner 100, thus reducing cooling efficiency. Effective separation and recovery of lubricating oil ensures that the compressor 10 receives adequate lubrication and cooling, thereby extending its service life and reducing maintenance costs.

[0047] The filter can remove impurities and contaminants such as moisture, dust, and particulate matter from the air conditioner 100, thereby protecting other components in the air conditioner 100 from damage by contaminants and maintaining the cleanliness and efficient operation of the air conditioner 100. By filtering out these impurities, the filter can ensure the smooth flow of refrigerant and other fluids in the refrigerant pipe 50, thereby improving the overall performance and efficiency of the air conditioner 100.

[0048] Thus, by selecting at least one of the following as a silencer, oil separator, and filter, the refrigerant pipe 50 can be prevented from bursting, while providing additional functions to the air conditioner 100, improving resource utilization and reducing costs.

[0049] Please see Figures 2 to 5 In some embodiments, the air conditioner 100 includes a four-way valve 60, a one-way valve 20 connected to the condenser 30 via the four-way valve 60, a volumetric container 40 connected to the refrigerant pipe 50 between the one-way valve 20 and the four-way valve 60, and / or the volumetric container 40 connected to the refrigerant pipe 50 between the four-way valve 60 and the condenser 30.

[0050] Thus, by installing a volume container 40 in the refrigerant pipe 50 between the one-way valve 20 and the four-way valve 60 and / or in the refrigerant pipe 50 between the four-way valve 60 and the condenser 30, the refrigerant in the refrigerant pipe 50 can enter the volume container 40 when it is at a high temperature, which can reduce or avoid the refrigerant pipe 50 from bursting to a certain extent, thereby avoiding damage to the air conditioner 100 during transportation and reducing the maintenance cost of the air conditioner 100 to a certain extent.

[0051] Specifically, the air conditioner 100 includes a four-way valve 60, which can change the flow direction of refrigerant in the refrigerant pipe 50, thereby enabling the air conditioner 100 to switch between cooling and heating modes. A one-way valve 20 is connected to the condenser 30 via the four-way valve 60, allowing the refrigerant in the refrigerant pipe 50 to flow into the condenser 30 after passing through the one-way valve 20 and the four-way valve 60. It should be noted that the condenser 30 can be the condenser 30 in the outdoor unit during cooling mode or the condenser 30 in the indoor unit during heating mode.

[0052] In some implementations, such as Figure 2 As shown, the volume container 40 can connect the refrigerant pipe 50 between the one-way valve 20 and the four-way valve 60, so that the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the four-way valve 60 can enter the volume container 40, thereby reducing the pressure generated by the refrigerant in the refrigerant pipe 50 under high temperature environment.

[0053] In some implementations, such as Figure 3 and Figure 4 As shown, the volumetric container 40 connects to the refrigerant pipe 50 between the four-way valve 60 and the condenser 30, allowing the refrigerant in the refrigerant pipe 50 to enter the volumetric container 40. This reduces the pressure generated by the refrigerant in the refrigerant pipe 50 under high-temperature conditions. It should be noted that the condenser 30 can be the condenser 30 in the outdoor unit during cooling mode or the condenser 30 in the indoor unit during heating mode.

[0054] In some implementations, such as Figure 5 As shown, the volume container 40 can be connected to the refrigerant pipe 50 between the one-way valve 20 and the four-way valve 60, the volume container 40 can be installed on the refrigerant pipe 50 between the four-way valve 60 and the condenser 30, and the volume container 40 can be installed on the refrigerant pipe 50 between the four-way valve 60 and the evaporator.

[0055] Please see Figure 6 In some embodiments, the air conditioner 100 includes at least one volume container 40, the total volume of which is determined based on the mass and density of the refrigerant between the one-way valve 20 and the condenser 30, and the actual volume of the refrigerant pipe 50 between the one-way valve 20 and the condenser 30.

[0056] In this way, by setting the number of volume containers 40 to multiple, and ensuring that the volume of the multiple volume containers 40 is determined by the mass and density of the refrigerant between the one-way valve 20 and the condenser 30, as well as the actual volume of the refrigerant pipe 50 between the one-way valve 20 and the condenser 30, it is possible to avoid pipe bursts caused by excessive refrigerant pressure due to insufficient volume, and to reduce the fluctuation and pressure changes of the refrigerant in the refrigerant pipe 50, thereby ensuring that the air conditioner 100 can continuously provide a stable cooling or heating effect.

[0057] Specifically, the number of volumetric containers 40 can be one or more. One or more volumetric containers 40 can be connected to the refrigerant pipe 50 between the one-way valve 20 and the condenser 30, and are used to contain the refrigerant between the one-way valve 20 and the condenser 30. When there are multiple volumetric containers 40, each volumetric container 40 can have a different function. For example, multiple volumetric containers 40 can include, but are not limited to, mufflers, oil separators, and filters.

[0058] Furthermore, the total volume of the multiple volumetric containers 40 needs to be determined based on the mass and density of the refrigerant between the check valve 20 and the condenser 30, as well as the actual volume of the refrigerant pipe 50 between the check valve 20 and the condenser 30. For example, by obtaining the mass and density of the refrigerant between the check valve 20 and the condenser 30, the minimum theoretical volume required to hold that mass of refrigerant can be calculated. Then, by subtracting the actual volume of the refrigerant pipe 50 from the minimum theoretical volume, the difference can be determined as the total volume of the multiple volumetric containers 40.

[0059] In some embodiments, the volume of the volume container 40 is determined by the cooling capacity range of the air conditioner 100.

[0060] In this way, by determining the cooling capacity range of the air conditioner 100, the refrigerant quantity of the corresponding air conditioner 100 can be obtained. Then, by looking up the table based on the refrigerant quantity, the volume of the volume container 40 can be determined without a complicated volume calculation process, thereby improving the speed of determining the volume of the volume container 40.

[0061] Specifically, the total volume of one or more volumetric containers 40 can be determined by the cooling capacity range of the air conditioner 100. The cooling capacity range of the air conditioner 100 can be expressed in refrigeration tons (LTTs), a unit of refrigeration that represents the cooling power required to freeze 1 ton of saturated water at 0°C to ice at 0°C in 24 hours. Therefore, the total volume of one or more volumetric containers 40 can be determined based on the cooling capacity range set at the time of manufacture of the air conditioner 100.

[0062] For example, when the cooling capacity of the air conditioner 100 is between 1 refrigeration ton and 1.5 refrigeration tons and between 1.5 refrigeration tons and 2 refrigeration tons, the total volume of one or more volumetric containers 40 can be between 0.2 liters and 0.9 liters; when the cooling capacity of the air conditioner 100 is between 2 refrigeration tons and 2.5 refrigeration tons, the total volume of one or more volumetric containers 40 can be between 0.3 liters and 1 liter; when the cooling capacity of the air conditioner 100 is between 2.5 refrigeration tons and 3 refrigeration tons and between 3 refrigeration tons and 3.5 refrigeration tons, the total volume of one or more volumetric containers 40 can be between 0.1 liters and 0.7 liters; when the cooling capacity of the air conditioner 100 is between 3.5 refrigeration tons and 4 refrigeration tons, the total volume of one or more volumetric containers 40 can be between 0.4 liters and 1 liter; when the cooling capacity of the air conditioner 100 is between 4 refrigeration tons and 4.5 refrigeration tons, the total volume of one or more volumetric containers 40 can be between 0.5 liters and 1.1 liters.

[0063] Please see Figure 1 , Figure 7 and Figure 8 The present invention provides a method for calculating the volume of a volumetric container 40 for use in an air conditioner 100. The air conditioner 100 includes a compressor 10, a one-way valve 20, a condenser 30, and a volumetric container 40. The compressor 10 is connected to the condenser 30 via the one-way valve 20. The volumetric container 40 is connected to a refrigerant pipe 50 between the one-way valve 20 and the condenser 30 and is used to contain the refrigerant between the one-way valve 20 and the condenser 30. The volumetric container 40 includes:

[0064] Step 011: Obtain the mass and density of the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the condenser 30, as well as the actual volume of the refrigerant pipe 50;

[0065] Step 012: Determine the minimum theoretical volume of refrigerant pipe 50 based on the mass and density of the refrigerant in refrigerant pipe 50;

[0066] Step 013: Determine the volume of container 40 based on the difference between the minimum theoretical volume and the actual volume.

[0067] Thus, by obtaining the mass and density of the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the condenser 30, as well as the actual volume of the refrigerant pipe 50, the volume of the volume container 40 can be determined. This avoids the situation where the volume container 40 is too small, resulting in insufficient pressure on the volume container 40, which could cause the pressure in the refrigerant pipe 50 to exceed the pressure bearing capacity and lead to pipe bursting. It also avoids the situation where the volume container 40 is too large, resulting in insufficient refrigerant flowing into the condenser 30 for heat exchange, thus reducing the heating or cooling effect.

[0068] The air conditioner 100 includes a compressor 10, a one-way valve 20, a condenser 30, and a volume container 40. The compressor 10 is connected to the condenser 30 via the one-way valve 20. The volume container 40 connects to a refrigerant pipe 50 between the one-way valve 20 and the condenser 30 and is used to contain the refrigerant between the one-way valve 20 and the condenser 30. The air conditioner 100 also includes a computing device 200, which includes a processor 210, a memory 220, and a computer program 221. The processor 210 is capable of executing the computer program 221, which contains instructions for calculating volume. The memory 220 is capable of storing the computer program 221, which contains instructions for calculating volume.

[0069] Specifically, the processor 210 can obtain the mass and density of the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the condenser 30, as well as the actual volume of the refrigerant pipe 50. For example, by installing a flow sensor in the refrigerant pipe 50 and calculating the refrigerant flow time, the mass of the refrigerant in the refrigerant pipe 50 can be determined based on the flow rate and time; by installing a density sensor in the refrigerant pipe 50 and reading the data displayed on the density sensor, the density of the refrigerant in the condenser pipe can be obtained; and by measuring the diameter and length of the refrigerant pipe 50, the actual volume of the refrigerant pipe 50 can be obtained.

[0070] Then, having obtained the mass and density of the refrigerant in the refrigerant pipe 50, the processor 210 can calculate and determine the minimum theoretical volume of the refrigerant pipe 50. The minimum theoretical volume refers to the minimum volume required to prevent the refrigerant pipe 50 from bursting under high-temperature conditions.

[0071] Finally, the processor 210 subtracts the minimum theoretical volume from the actual volume of the refrigerant pipe 50, and the difference obtained by the processor 210 is the volume of the volumetric container 40. By inputting excess refrigerant from the refrigerant pipe 50 into the additional volumetric container 40, pipe bursts caused by increased pressure at high temperatures can be avoided.

[0072] Please see Figure 9 In some embodiments, step 011: obtaining the density of the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the condenser 30 includes:

[0073] Step 0111: Obtain the highest ambient temperature of the refrigerant in the refrigerant pipe 50 and the withstand pressure at the weakest point in the refrigerant pipe 50;

[0074] Step 0112: Determine the density of the refrigerant in the refrigerant pipe 50 based on the preset mapping relationship of temperature, pressure and density, the highest ambient temperature and the withstand pressure.

[0075] Thus, by substituting the highest ambient temperature of the refrigerant in the refrigerant pipe 50 and the pressure resistance at the weakest point in the refrigerant pipe 50 into the preset mapping relationship of temperature, pressure and density, the density of the refrigerant in the refrigerant pipe 50 can be determined, thereby accurately obtaining the density of the refrigerant and improving the accuracy of determining the volume of the volume container 40.

[0076] Specifically, the processor 210 can obtain the density of the refrigerant in the refrigerant pipe 50 between the one-way valve 20 and the condenser 30 by acquiring the highest ambient temperature of the refrigerant in the refrigerant pipe 50 and the withstand pressure at the weakest point in the refrigerant pipe 50, and determine the density based on a preset mapping relationship between temperature, pressure, and density. Specifically, the highest ambient temperature of the refrigerant in the refrigerant pipe 50 can be obtained by installing multiple temperature sensors in the refrigerant pipe 50, detecting the temperature of the refrigerant through these sensors, and comparing the collected temperature data.

[0077] The pressure resistance of the weakest part in the refrigerant pipe 50 can be obtained by setting multiple pressure sensors in the refrigerant pipe 50, detecting the pressure resistance of the deformed parts in the refrigerant pipe 50 by multiple pressure sensors, comparing the collected pressure data, and determining the pressure resistance of the part with the greatest degree of deformation as the pressure resistance of the weakest part in the refrigerant pipe 50.

[0078] Given the maximum ambient temperature and withstand pressure of the refrigerant, the processor 210 can determine the density of the refrigerant in the refrigerant pipe 50 based on a preset mapping relationship between temperature, pressure, and density, as well as the maximum ambient temperature and withstand pressure. The preset mapping relationship can be a state equation showing the change in refrigerant density with ambient temperature and withstand pressure; by substituting the ambient temperature and withstand pressure into the state equation, the density of the refrigerant can be determined. Alternatively, the preset mapping relationship can be a table showing the change in refrigerant density with ambient temperature and withstand pressure; by querying the table based on the ambient temperature and withstand pressure, the density of the refrigerant can be determined.

[0079] Thus, by substituting the highest ambient temperature of the refrigerant in the refrigerant pipe 50 and the pressure resistance at the weakest point in the refrigerant pipe 50 into a preset state equation or by querying a preset table, the efficiency of determining the refrigerant density can be improved.

[0080] Please see Figure 1 , Figure 8 and Figure 10The present invention provides a method for calculating the volume of a volumetric container 40 for use in an air conditioner 100. The air conditioner 100 includes a compressor 10, a one-way valve 20, a condenser 30, and a volumetric container 40. The compressor 10 is connected to the condenser 30 via the one-way valve 20. The volumetric container 40 is connected to a refrigerant pipe 50 between the one-way valve 20 and the condenser 30 and is used to contain the refrigerant between the one-way valve 20 and the condenser 30. The volumetric container 40 includes:

[0081] Step 021: Obtain the preset cooling capacity range of the air conditioner 100;

[0082] Step 022: Determine the volume of the volume container 40 based on the preset mapping relationship between the cooling capacity segment and the volume and the preset cooling capacity segment.

[0083] Thus, by determining the volume of the volume container 40 based on the preset mapping relationship between the cooling capacity range and the volume of the air conditioner 100, the efficiency of determining the volume of the volume container 40 can be improved.

[0084] The air conditioner 100 includes a compressor 10, a one-way valve 20, a condenser 30, and a volume container 40. The compressor 10 is connected to the condenser 30 via the one-way valve 20. The volume container 40 connects to a refrigerant pipe 50 between the one-way valve 20 and the condenser 30 and is used to contain the refrigerant between the one-way valve 20 and the condenser 30. The air conditioner 100 also includes a computing device 200, which includes a processor 210, a memory 220, and a computer program 221. The processor 210 is capable of executing the computer program 221, which contains instructions for calculating volume. The memory 220 is capable of storing the computer program 221, which contains instructions for calculating volume.

[0085] Specifically, different air conditioners 100 are equipped with different cooling capacity ranges, and different cooling capacity ranges require different amounts of refrigerant. As shown in Table 1,

[0086] Table 1

[0087] Cooling capacity range / ton Volume of container / L 1-1.5 0.2-0.9 1.5-2 0.2-0.9 2-2.5 0.3-1.0 2.5-3 0.1-0.7 3-3.5 0.1-0.7 3.5-4 0.4-1.0 4-5 0.5-1.1

[0088] Specifically, when the cooling capacity of air conditioner 100 is between 1 refrigeration ton and 1.5 refrigeration tons, the refrigerant quantity is 1.3 kg to 1.6 kg; when the cooling capacity of air conditioner 100 is between 1.5 refrigeration tons and 2 refrigeration tons, the refrigerant quantity is 1.5 kg to 1.8 kg; when the cooling capacity of air conditioner 100 is between 2 refrigeration tons and 2.5 refrigeration tons, the refrigerant quantity is 1.6 kg to 1.9 kg; and when the cooling capacity of air conditioner 100 is between 2.5 refrigeration tons and 2.5 refrigeration tons, the refrigerant quantity is 1.6 kg to 1.9 kg. For air conditioners with a cooling capacity of 3 to 3 tons, the refrigerant quantity is 1.5 kg to 1.7 kg; for those with a cooling capacity of 3 to 3.5 tons, the refrigerant quantity is 1.8 kg to 2 kg; for those with a cooling capacity of 3.5 to 4 tons, the refrigerant quantity is 1.9 kg to 2.1 kg; and for those with a cooling capacity of 4 to 5 tons, the refrigerant quantity is 2.1 kg to 2.3 kg. Therefore, the volume of the container 40 varies depending on the cooling capacity range.

[0089] The processor 210 can obtain the preset cooling capacity range of the air conditioner 100. For example, the value of the preset cooling capacity range of the air conditioner 100 is stored in the memory 220, and the processor 210 can obtain the corresponding cooling capacity range of the air conditioner 100 by calling the memory 220.

[0090] The processor 210 can determine the volume of the volume container 40 corresponding to the air conditioner 100 based on a preset mapping relationship between cooling capacity segment and volume. For example, the preset mapping relationship between cooling capacity segment and volume can be a table showing how the volume of the volume container 40 changes with the cooling capacity segment. The processor 210 can look up the table based on the cooling capacity segment to determine the volume of the volume container 40 corresponding to the air conditioner 100.

[0092] Specifically, the electronic device 400 includes, but is not limited to, air conditioner 100, mobile phone, tablet computer, personal computer, server, wearable smart device, etc.
