Description
Technical Field
[0001] This application relates to the field of air conditioning, and more particularly to a method, apparatus, and electronic equipment for defrosting water in a multi-split air conditioner. Background Technology
[0002] Multi-split dual-generation heat pump systems can provide domestic hot water or underfloor heating hot water while offering the cooling and heating functions of a typical multi-split unit, thus enriching the functionality of the heat pump system. Conventional split-type dual-generation systems separate the outdoor unit and generator, increasing the system's space requirements. Therefore, integrated dual-generation units, where the outdoor unit and generator are integrated and installed outdoors, have become a popular design. One layout of the integrated dual-generation system places the outdoor unit on top and the generator below. With its more aesthetically pleasing appearance and similar bottom-outlet piping design to conventional multi-split units, it offers significant advantages in both appearance and installation. This layout has two chassis: the outdoor unit chassis and the generator chassis. When the outdoor unit defrosts, the defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the outdoor unit chassis drain hole to the generator chassis, and finally through the generator chassis drain hole to the outside of the unit. The defrost water flow is longer, and improper handling can easily cause defrost water to accumulate, which in severe cases can lead to components being submerged in water and frozen.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0028] According to a first aspect of the embodiments of this application, a method for draining defrost water from a multi-split air conditioner is provided, optionally, as follows: Figure 1 As shown, the above method includes:
[0029] S102, when the multi-split air conditioner starts defrosting, detect the ambient temperature of the multi-split air conditioner;
[0030] S104, detect the first temperature of the first drain hole, wherein the first drain hole is the drain hole of the outdoor unit chassis of the multi-split air conditioner; detect the second temperature of the second drain hole, wherein the second drain hole is the drain hole of the generator chassis of the multi-split air conditioner.
[0031] S106 controls the heating module of the multi-split air conditioner to turn on based on the ambient temperature, the first temperature, and the second temperature. The heating module is located at the bottom of the outdoor unit chassis and the generator chassis.
[0032] Alternatively, the layout of multi-split air conditioning units can be as follows: Figure 2 As shown, the outdoor unit is positioned at the top, with the generator located below it. This design is aesthetically pleasing, and the water and refrigerant pipes exit from the lower right side of the unit for easy installation. This layout involves a two-tiered chassis, as... Figure 3As shown, the outdoor unit chassis and generator chassis are connected. When the outdoor unit defrosts, defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the outdoor unit chassis drain hole to the generator chassis, and finally through the generator chassis drain hole to be discharged outside the unit. This longer defrost water flow path can easily lead to defrost water accumulation if not handled properly, potentially causing components to freeze and become submerged. Therefore, in this embodiment, an electric heater is installed on both the outdoor unit chassis and the generator chassis to heat both chassis during the defrosting and drainage process, ensuring smooth drainage of defrost water without freezing. Temperature detectors are also installed on the drain holes of both chassis to monitor the drainage temperature. Specifically, when the multi-split air conditioner starts defrosting, it detects the ambient temperature, the first temperature of the first drain hole, and the second temperature of the second drain hole. Then, based on the ambient temperature, the first temperature, and the second temperature, it controls the heating module to turn on, so that the heating module heats the outdoor unit chassis and the generator chassis, ensuring that the defrost water is discharged smoothly and does not freeze. This achieves the goal of smooth discharge of defrost water when the multi-split air conditioner is draining, and thus solves the technical problem of defrost water accumulation caused by the long process when draining defrost water in multi-split air conditioners.
[0033] As an optional example, controlling the heating module of a multi-split air conditioner to turn on based on the ambient temperature, a first temperature, and a second temperature includes:
[0034] When the ambient temperature is less than or equal to the first preset temperature, the first heater of the control heating module is turned on, wherein the first heater is located at the bottom of the outdoor unit chassis;
[0035] When the first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, the second heater of the heating module is turned on, wherein the second heater is located at the bottom of the generator chassis;
[0036] If the second temperature is less than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration, the first heater and the second heater are controlled to shut down.
[0037] Optionally, when the outdoor unit of a multi-split air conditioner defrosts, the defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the drain hole of the outdoor unit chassis to the generator chassis, and finally through the drain hole of the generator chassis to the outside of the unit. This longer defrost water flow path can easily lead to defrost water accumulation if not handled properly, potentially causing components to freeze and be damaged. Therefore, in this embodiment, when the multi-split air conditioner starts defrosting, the outdoor ambient temperature is detected. If the outdoor ambient temperature is less than or equal to a first preset temperature (which can be zero degrees Celsius), the defrost water discharged at this time can... The water may freeze due to low temperatures. Therefore, the first heater located under the outdoor unit chassis is activated first to heat the defrost water in the outdoor unit chassis, allowing it to flow fully from the outdoor unit chassis to the lower generator chassis. The first temperature of the drain hole on the outdoor unit chassis is monitored. When the first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, it indicates that a small amount of defrost water has accumulated on the generator chassis. At this point, the second heater located on the generator chassis is activated to allow the defrost water to drain completely from the generator chassis. After the second heater is activated, the second temperature of the drain hole on the generator chassis is monitored. When the second temperature is less than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration, it indicates that the defrost water has been completely drained. Then, the first and second heaters on both chassis are simultaneously turned off, thereby reducing energy consumption while ensuring the complete and smooth drainage of defrost water. When a small amount of defrost water accumulates on the generator chassis, the second heater installed on the generator chassis should be turned on. This avoids accidentally turning on the second heater when there is very little defrost water and it can be discharged smoothly without the need to start the second heater, which would increase energy consumption. This can reduce energy consumption.
[0038] To illustrate with an example, this application designs a method for draining defrost water from a multi-split air conditioner. The multi-split air conditioner is arranged with the outdoor unit on top and the generator below it. Water pipes and refrigerant pipes all exit from the lower right side of the unit. There are two chassis: the outdoor unit chassis and the generator chassis. When the outdoor unit defrosts, defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the outdoor unit chassis drain hole to the generator chassis, and finally through the generator chassis drain hole to the outside of the unit. Therefore, an electric heater is installed on both the outdoor unit chassis and the generator chassis to heat both chassis during the defrosting and draining process, ensuring smooth drainage of defrost water without freezing. Temperature detectors are also installed on the drain holes of both chassis to monitor the drainage temperature. The specific implementation process is as follows: Figure 4 As shown:
[0039] Step 1: When the multi-split air conditioner starts defrosting, detect the outdoor ambient temperature and determine whether the outdoor ambient temperature is less than or equal to the first preset temperature. If so, proceed to Step 2.
[0040] Step 2: Turn on the first heater installed under the outdoor unit chassis;
[0041] Step 3: Determine whether the first temperature of the drain hole on the outdoor unit chassis is greater than or equal to the second preset temperature. If so, proceed to Step 4.
[0042] Step 4: Determine whether the duration during which the first temperature is greater than or equal to the second preset temperature is greater than or equal to the first preset duration. If so, proceed to Step 5.
[0043] Step 5: Turn on the second heater installed on the generator chassis;
[0044] Step 6: Determine whether the second temperature of the drain hole of the generator chassis is less than or equal to the third preset temperature. If so, proceed to Step 7.
[0045] Step 7: Determine whether the duration during which the second temperature is greater than or equal to the third preset temperature is greater than or equal to the second preset duration. If so, proceed to Step 8.
[0046] Step 8: Turn off the first and second heaters.
[0047] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.
[0048] According to a second aspect of the embodiments of this application, a defrosting water device for a multi-split air conditioner is also provided, such as... Figure 5 As shown, it includes:
[0049] The first detection module 502 is used to detect the ambient temperature of the multi-split air conditioner when the multi-split air conditioner starts defrosting.
[0050] The second detection module 504 is used to detect the first temperature of the first drain hole, wherein the first drain hole is the drain hole of the outdoor unit chassis;
[0051] The third detection module 506 is used to detect the second temperature of the second drain hole, wherein the second drain hole is the drain hole of the generator chassis;
[0052] The control module 508 is used to control the heating module of the multi-split air conditioner to turn on according to the ambient temperature, the first temperature and the second temperature. The heating module is located at the bottom of the outdoor unit chassis and the generator chassis of the multi-split air conditioner.
[0053] Alternatively, the layout of multi-split air conditioning units can be as follows: Figure 2 As shown, the outdoor unit is positioned at the top, with the generator located below it. This design is aesthetically pleasing, and the water and refrigerant pipes exit from the lower right side of the unit for easy installation. This layout involves a two-tiered chassis, as... Figure 3 As shown, the outdoor unit chassis and generator chassis are connected. When the outdoor unit defrosts, defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the outdoor unit chassis drain hole to the generator chassis, and finally through the generator chassis drain hole to be discharged outside the unit. This longer defrost water flow path can easily lead to defrost water accumulation if not handled properly, potentially causing components to freeze and become submerged. Therefore, in this embodiment, an electric heater is installed on both the outdoor unit chassis and the generator chassis to heat both chassis during the defrosting and drainage process, ensuring smooth drainage of defrost water without freezing. Temperature detectors are also installed on the drain holes of both chassis to monitor the drainage temperature. Specifically, when the multi-split air conditioner starts defrosting, it detects the ambient temperature, the first temperature of the first drain hole, and the second temperature of the second drain hole. Then, based on the ambient temperature, the first temperature, and the second temperature, it controls the heating module to turn on, so that the heating module heats the outdoor unit chassis and the generator chassis, ensuring that the defrost water is discharged smoothly and does not freeze. This achieves the goal of smooth discharge of defrost water when the multi-split air conditioner is draining, and thus solves the technical problem of defrost water accumulation caused by the long process when draining defrost water in multi-split air conditioners.
[0054] As an optional example, the control module described above includes:
[0055] The first control unit is used to control the first heater of the heating module to turn on when the ambient temperature is less than or equal to the first preset temperature, wherein the first heater is located at the bottom of the outdoor unit chassis;
[0056] The second control unit is used to control the second heater of the heating module to turn on when the first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, wherein the second heater is located at the bottom of the generator chassis;
[0057] The third control unit is used to control the first heater and the second heater to shut down when the second temperature is less than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration.
[0058] When the outdoor unit of a multi-split air conditioner defrosts, defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the drain hole of the outdoor unit chassis to the generator chassis, and finally through the drain hole of the generator chassis to be discharged outside the unit. This longer defrost water flow path can easily lead to defrost water accumulation if not handled properly, potentially causing components to freeze and become submerged. Therefore, in this embodiment, when the multi-split air conditioner starts defrosting, the outdoor ambient temperature is detected. If the outdoor ambient temperature is less than or equal to a first preset temperature (which can be zero degrees Celsius), the discharged defrost water may... Because the temperature is too low and the water is freezing, the first heater located under the outdoor unit chassis is activated first to heat the defrost water in the outdoor unit chassis, allowing it to flow fully from the outdoor unit chassis to the lower generator chassis. The first temperature at the drain hole of the outdoor unit chassis is then monitored. When the first temperature is greater than or equal to the second preset temperature, and the duration is greater than or equal to the first preset duration, it indicates that a small amount of defrost water has accumulated on the generator chassis. At this point, the second heater located on the generator chassis is activated to allow the defrost water to drain completely from the generator chassis. After the second heater is activated, the second temperature at the drain hole of the generator chassis is monitored. When the second temperature is less than or equal to the third preset temperature, and the duration is greater than or equal to the second preset duration, it indicates that the defrost water has been completely drained. Then, the first and second heaters on both chassis are simultaneously turned off, thus reducing energy consumption while ensuring the complete and smooth drainage of defrost water. When a small amount of defrost water accumulates on the generator chassis, the second heater installed on the generator chassis should be turned on. This avoids accidentally turning on the second heater when there is very little defrost water and it can be discharged smoothly without the need to start the second heater, which would increase energy consumption. This can reduce energy consumption.
[0059] For other examples of this embodiment, please refer to the examples above, which will not be repeated here.
[0060] According to a third aspect of the embodiments of this application, this application provides a defrosting water device for a multi-split air conditioner, such as... Figure 6 As shown, it includes:
[0061] Temperature detection module 602 is installed on the outdoor unit chassis and generator chassis of the multi-split air conditioner. The temperature detection module is used to detect the ambient temperature, the first temperature of the first drain hole and the second temperature of the second drain hole when the multi-split air conditioner starts defrosting. The first drain hole is the drain hole of the outdoor unit chassis and the second drain hole is the drain hole of the generator chassis.
[0062] Heating module 604 is located at the bottom of the outdoor unit chassis and the generator chassis. The heating module is used to heat the defrost water in the outdoor unit chassis and the generator chassis.
[0063] The control module 606 is used to control the heating module to turn on based on the ambient temperature, the first temperature, and the second temperature.
[0064] Alternatively, the layout of multi-split air conditioning units can be as follows: Figure 2 As shown, the outdoor unit is positioned at the top, with the generator located below it. This design is aesthetically pleasing, and the water and refrigerant pipes exit from the lower right side of the unit for easy installation. This layout involves a two-tiered chassis, as... Figure 3 As shown, the outdoor unit chassis and generator chassis are connected. When the outdoor unit defrosts, defrost water first flows from the outdoor unit heat exchanger to the outdoor unit chassis, then through the drain hole of the outdoor unit chassis to the generator chassis, and finally through the drain hole of the generator chassis to be discharged outside the unit. This longer defrost water flow path can easily lead to defrost water accumulation if not handled properly, potentially causing components to freeze and be damaged. Therefore, in this embodiment, temperature detection modules are installed at the first drain hole of the outdoor unit chassis and the second drain hole of the generator chassis, and heating modules are installed at the bottom of the outdoor unit chassis and the generator chassis. A control module is installed on the multi-split air conditioner. When the outdoor unit defrosts, the temperature detection modules detect the ambient temperature, the first temperature at the first drain hole, and the second temperature at the second drain hole. Based on the ambient temperature, the first temperature, and the second temperature, the control module controls the heating module to activate, allowing the heating module to heat both chassis and ensure smooth drainage of defrost water without freezing. This achieves the goal of ensuring smooth discharge of defrost water during the defrost water drainage process of multi-split air conditioners, thereby solving the technical problem of defrost water accumulation caused by excessively long drainage flow in multi-split air conditioners.
[0065] As an optional example, the temperature detection module includes:
[0066] The first temperature detector is used to detect the ambient temperature;
[0067] A second temperature detector is used to detect the first temperature;
[0068] The third temperature detector is used to detect the second temperature.
[0069] Optionally, in this embodiment, the temperature detection module includes a first temperature detector, a second temperature detector, and a third temperature detector. The first temperature detector is located outside the multi-split air conditioner and is used to detect the outdoor ambient temperature. The second temperature detector is located at the first drain hole of the outdoor unit chassis and is used to detect the first temperature of the first drain hole of the outdoor unit chassis. The third temperature detector is located at the second drain hole of the generator chassis and is used to detect the second temperature of the second drain hole of the generator chassis. When the outdoor ambient temperature is less than or equal to a first preset temperature, it indicates that the defrost water discharged at this time may freeze due to the low temperature. When the first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, it indicates that the defrost water has been discharged from the first drain hole of the outdoor unit chassis for a period of time. When the second temperature is greater than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration, it indicates that the defrost water has been discharged from the second drain hole of the generator chassis for a period of time.
[0070] As an optional example, the heating module includes:
[0071] The first heater is used to heat the defrost water in the outdoor unit chassis;
[0072] The second heater is used to heat the defrosting water in the generator chassis.
[0073] Optionally, in this embodiment, the heating module includes a first heater and a second heater. The first heater is installed on the outdoor unit chassis and heats the defrost water in the outdoor unit chassis during the defrost and drainage process. The second heater is installed on the generator chassis and heats the defrost water in the generator chassis during the defrost and drainage process, thereby ensuring that the defrost water is drained smoothly without freezing.
[0074] As an alternative example, the control module controls the first heater to turn on when the ambient temperature is less than or equal to a first preset temperature.
[0075] Optionally, in this embodiment, when the multi-split air conditioner starts defrosting, the outdoor ambient temperature is detected by the first temperature detector. If the outdoor ambient temperature is less than or equal to the first preset temperature (which can be zero degrees Celsius), the defrosting water discharged may freeze due to the low temperature. Therefore, the control module first controls the first heater installed under the outdoor unit chassis to turn on, so that the first heater heats the outdoor unit chassis, thereby allowing the defrosting water to flow smoothly from the outdoor unit chassis to the generator chassis below.
[0076] As an alternative example, after the control module controls the first heater to turn on, if the first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, the control module controls the second heater to turn on.
[0077] Optionally, in this embodiment, after the first heater is turned on, the first temperature of the first drain hole on the outdoor unit chassis is detected by the second temperature detector. When the detected first temperature is greater than or equal to the second preset temperature and the duration is greater than or equal to the first preset duration, it indicates that a small amount of defrost water has accumulated on the generator chassis. At this time, the control module then controls the second heater installed on the generator chassis to turn on, so that the second heater heats the defrost water in the generator chassis, allowing the defrost water to be smoothly discharged from the second drain hole of the generator chassis. By controlling the second heater installed on the generator chassis to turn on only when a small amount of defrost water has accumulated on the generator chassis, it avoids accidentally turning on the second heater when there is very little defrost water and it does not need to be turned on to drain smoothly, thus increasing energy consumption and reducing energy consumption.
[0078] As an optional example, after the second heater is turned on, if the second temperature is less than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration, the first heater and the second heater are turned off.
[0079] Optionally, when the multi-split air conditioner starts defrosting, the outdoor unit chassis and generator chassis are heated by the first heater and the second heater to ensure that defrost water is fully drained from the outdoor unit chassis and generator chassis. If the heater is not turned off in time after the defrost water has been fully drained from the generator chassis, it will also lead to increased energy consumption. Therefore, in this embodiment, after the second heater is turned on, the second temperature of the second drain hole of the generator chassis is detected by the third temperature detector. When the second temperature is less than or equal to the third preset temperature and the duration is greater than or equal to the second preset duration, it indicates that the defrost water has been completely drained. Then, the first heater and the second heater are turned off at the same time, thereby reducing energy consumption while the defrost water can be completely drained smoothly.
[0080] For other examples of this embodiment, please refer to the examples above, which will not be repeated here.

Figure 7 As shown, it includes a processor 702, a communication interface 704, a memory 706, and a communication bus 708. The processor 702, communication interface 704, and memory 706 communicate with each other via the communication bus 708.
[0082] Memory 706 is used to store computer programs;
[0083] When processor 702 executes a computer program stored in memory 706, it performs the following steps:
[0084] When the multi-split air conditioner starts defrosting, measure the ambient temperature of the multi-split air conditioner.
