[0002] When the outdoor environment is cold and the indoor unit of the air conditioner is used for heating, frost can easily form on the heat exchanger of the outdoor unit, which can lead to increased energy consumption, reduced heating efficiency, or even prevent the air conditioner from working properly.

[0003] When the outdoor unit of an existing air conditioner has a lot of frost, it usually switches the indoor unit to cooling mode, so that the outdoor unit acts as a condenser, thereby raising its temperature to achieve the purpose of defrosting; at the same time, it closes the indoor unit fan and the indoor unit air outlet to prevent cold air from entering the room.

[0004] However, the defrosting process in existing technologies usually lasts about 10 minutes. During this time, the indoor unit cannot heat or blow hot air, which still affects the perceived indoor temperature. Furthermore, when the outdoor unit temperature is lower, defrosting needs to be performed more frequently, resulting in frequent shutdowns of the indoor heating system and a poor user experience.

The singular terms "a" or "this" can also include plural forms.

[0054] In order to ensure that the indoor unit continues to heat the air conditioner while the outdoor unit is defrosting, the present invention provides an air conditioner control method.

[0055] The air conditioner control method of the present invention is applied to air conditioners; please refer to the appendix for details. Figure 2-5The diagram shows the structure of an air conditioner.

[0056] like Figure 2-5 As shown, the air conditioner includes an outdoor unit 10 and indoor units 8 and 9. The outdoor unit 10 includes a first outdoor unit heat exchanger 3b, a second outdoor unit heat exchanger 4b, and a compressor 1. The air conditioner is equipped with a first four-way valve 3a and a second four-way valve 4a. The first four-way valve 3a is used to selectively connect the first outdoor unit heat exchanger 3b to the air inlet or exhaust port of the compressor 1. The second four-way valve 4a is used to selectively connect the second outdoor unit heat exchanger 4b to the air inlet or exhaust port of the compressor.

[0057] For example, in the outdoor unit 10, the first outdoor unit heat exchanger 3b and the second outdoor unit heat exchanger 4b can be divided vertically as shown in the figure, or they can be divided horizontally, or other division forms.

[0058] In one embodiment, both the first four-way valve 3a and the second four-way valve 4a are provided with capillary tubes, and the two ports connected by the capillary tubes cannot form a passage, so that the first four-way valve 3a and the second four-way valve 4a satisfy the above-described connection relationship. In other embodiments of the present invention, four-way valves that satisfy the above-described connection relationship can also be obtained by other means.

[0059] See appendix Figure 1 , Figure 1 This is a flowchart illustrating the main steps of an air conditioner control method according to an embodiment of the present invention. Figure 1 As shown, the air conditioner control method in this embodiment of the invention mainly includes the following steps S11-S12.

[0060] Step S11: In response to the defrost command, based on the control of the connection status of the first four-way valve and the second four-way valve, the outdoor unit switches from the heating mode to the first defrost mode or the second defrost mode.

[0061] Furthermore, the air conditioner also includes a heating valve 5 and a cooling valve 6, which are used to control the switching of the heating mode and cooling mode of the indoor units 8 and 9, respectively. When the indoor units 8 and 9 are in heating mode, a refrigerant passage is formed between the exhaust port of the compressor 1 and the indoor units 8 and 9. When the first four-way valve 3a is energized (ON), a refrigerant passage is formed between the first outdoor unit heat exchanger 3b and the air inlet of the compressor 1. When it is de-energized (OFF), a refrigerant passage is formed between the exhaust port of the compressor 1 and the first outdoor unit heat exchanger 3b. When the second four-way valve 4a is energized (ON), a refrigerant passage is formed between the second outdoor unit heat exchanger 4b and the air inlet of the compressor 1. When it is de-energized (OFF), a refrigerant passage is formed between the exhaust port of the compressor 1 and the second outdoor unit heat exchanger 4b.

[0062] In one embodiment, the outdoor unit switches from heating mode to a first defrost mode or a second defrost mode. The method further includes: when the outdoor unit 10 is in heating mode, controlling the first four-way valve 3a to be energized (ON), the second four-way valve 3b to be energized (ON), the heating valve 5 to be opened (OPEN), and the cooling valve 6 to be closed (CLOSE).

[0063] Please refer to the attached document. Figure 2 , Figure 2 This is a schematic diagram of the structure of an air conditioner according to the first embodiment of the present invention. In this embodiment, the outdoor unit 10 is in heating mode, and the indoor units 8 and 9 are also in heating mode.

[0064] In other embodiments of the present invention, the number of indoor units is not limited to the two in the example, and can be set to one or more as needed. Some indoor units may be in a closed state, while the indoor units in the open state are in heating mode.

[0065] The first defrosting mode is the defrosting operation mode of the first outdoor unit heat exchanger 3b, and the second defrosting mode is the defrosting operation mode of the second outdoor unit heat exchanger 4b.

[0066] In step S12, if the first defrost mode is activated, the heat exchanger of the first outdoor unit defrosts while the indoor unit continues to heat; if the second defrost mode is activated, the heat exchanger of the second outdoor unit defrosts while the indoor unit continues to heat.

[0067] Furthermore, the method includes:

[0068] When the first defrost mode is activated, the first four-way valve 3a is de-energized (OFF), the second four-way valve 4a is energized (ON), the heating valve 5 is opened (OPEN), and the cooling valve 6 is closed (CLOSE).

[0069] Please refer to the attached document. Figure 3 , Figure 3 This is a schematic diagram of the structure of an air conditioner according to a second embodiment of the present invention. In this embodiment, the outdoor unit 10 is in the first defrosting mode, while the indoor units 8 and 9 are in the heating mode.

[0070] When the first defrost mode is running, the refrigerant becomes a high-temperature and high-pressure gas after passing through the compressor 1. After leaving the exhaust port of the compressor 1 and passing through the oil separator 2, it flows in two separate paths to the first outdoor unit heat exchanger 3b and the gas pipe 12. The refrigerant in the gas pipe 12 passes through the indoor unit heat exchanger (the first indoor unit heat exchanger 8b and the second indoor unit heat exchanger 9b in the figure), and then passes through the liquid pipe 11 to merge with the refrigerant that has passed through the first outdoor unit heat exchanger 3b at point M. After merging, the refrigerant passes through the second outdoor unit heat exchanger 4b and the gas-liquid separator 7 in sequence before returning to the air inlet of the compressor 1, forming a refrigerant cycle.

[0071] At this time, the first outdoor unit heat exchanger 3b acts as a condenser, and the second outdoor unit heat exchanger 4b acts as an evaporator; the first indoor unit heat exchanger 8b and the second indoor unit heat exchanger 9b act as condensers.

[0072] When the second defrost mode is activated, the first four-way valve 3a is powered on (ON), the second four-way valve 4a is powered off (OFF), the heating valve 5 is opened (OPEN), and the cooling valve 6 is closed (CLOSE).

[0073] Please refer to the attached document. Figure 4 , Figure 4 This is a schematic diagram of the structure of an air conditioner according to the third embodiment of the present invention. In this embodiment, the outdoor unit 10 is in the second defrosting mode, while the indoor units 8 and 9 are in the heating mode.

[0074] When the second defrost mode is running, the refrigerant becomes a high-temperature and high-pressure gas after passing through the compressor 1. After leaving the exhaust port of the compressor 1 and passing through the oil separator 2, it flows in two separate paths to the second outdoor unit heat exchanger 4b and the gas pipe 12. The refrigerant in the gas pipe 12 passes through the indoor unit heat exchanger (the first indoor unit heat exchanger 8b and the second indoor unit heat exchanger 9b in the figure), and then passes through the liquid pipe 11 to merge with the refrigerant that has passed through the second outdoor unit heat exchanger 4b at point M. After merging, the refrigerant passes through the first outdoor unit heat exchanger 3b and the gas-liquid separator 7 in sequence before returning to the air inlet of the compressor 1, forming a refrigerant cycle.

[0075] At this time, the second outdoor unit heat exchanger 4b acts as a condenser, and the first outdoor unit heat exchanger 3b acts as an evaporator; the first indoor unit heat exchanger 8b and the second indoor unit heat exchanger 9b act as condensers.

[0076] Furthermore, to ensure the safe operation of the air conditioner, multiple electronic expansion valves are also provided, including a first outdoor unit electronic expansion valve 3d and a second outdoor unit electronic expansion valve 4d installed in the outdoor unit 10, a first indoor unit electronic expansion valve 8a installed in the first indoor unit 8, and a second indoor unit electronic expansion valve 9a installed in the second indoor unit 9. Shut-off valves may also be installed on the gas pipe 12 and the liquid pipe 11.

[0077] In one embodiment, the heating valve 5 and the cooling valve 6 may be electronic expansion valves or solenoid valves, so as to switch the heating mode and cooling mode of the air conditioner by controlling the opening and closing of the heating valve 5 and the cooling valve 6.

[0078] Furthermore, in one embodiment, the heating valve 5 is an electronic expansion valve, and the method further includes: adjusting the defrosting speed of the outdoor unit 10 based on the control of the opening degree of the heating valve 5.

[0079] Since the refrigerant flows in two streams during defrosting, to the gas pipe 12 and the outdoor unit heat exchanger, adjusting the opening of the heating valve 5 at this time can regulate the flow ratio of refrigerant to the indoor and outdoor units, thereby adjusting the defrosting speed of the outdoor unit 10. Those skilled in the art can control the opening of the heating valve 5 according to actual conditions to control the defrosting speed while also ensuring indoor heating.

[0080] In addition, the air conditioner can also be switched to cooling mode; please refer to the appendix. Figure 5 , Figure 5 This is a schematic diagram of the structure of an air conditioner according to the fourth embodiment of the present invention. In this embodiment, the outdoor unit 10 is in cooling mode, while the indoor units 8 and 9 are in cold mode.

[0081] When the cooling mode is turned on, the first four-way valve 3a is de-energized (OFF), the second four-way valve 4a is de-energized (OFF), the heating valve 5 is closed (CLOSE), and the cooling valve 6 is opened (OPEN).

[0082] Furthermore, in one embodiment, the outdoor unit is further provided with a first defrost sensor and a second defrost sensor, respectively used to collect the temperature values ​​of the first outdoor unit heat exchanger and the second outdoor unit heat exchanger; the method further includes:

[0083] Based on the temperature data collected by the first defrost sensor and the second defrost sensor, it is determined whether the first outdoor unit heat exchanger and the second outdoor unit heat exchanger have reached the preset defrost temperature value.

[0084] If the first defrost sensor reaches the defrost temperature value first, then the first defrost mode is activated;

[0085] If the second defrost sensor reaches the defrost temperature value first, the second defrost mode will be activated.

[0086] In one technical solution of the above-mentioned air conditioner control method, after the outdoor unit switches from heating mode to the first defrost mode or the second defrost mode, the method further includes:

[0087] After the first or second defrost mode is completed, determine whether defrosting needs to continue.

[0088] If so, then reacquire the temperature data collected by the first defrost sensor and the second defrost sensor, and return to the step "Based on the temperature data collected by the first defrost sensor and the second defrost sensor, determine whether the first outdoor unit heat exchanger and the second outdoor unit heat exchanger have reached the preset defrost temperature value".

[0089] If not, defrosting ends and the outdoor unit returns to heating mode.

[0090] For example, in one embodiment, the determination of whether defrosting needs to continue can be based on the defrosting program that has been running. If the first defrosting mode and the second defrosting mode have been run in this defrosting, then defrosting does not need to continue; otherwise, defrosting needs to continue.

[0091] Based on the above steps S11-S12, and based on the control of the connection status of the first four-way valve and the second four-way valve, the outdoor unit is switched from the heating mode to the first defrost mode or the second defrost mode, so as to achieve the effect of continuous heating of the indoor unit while the outdoor unit is defrosting, thus optimizing the indoor temperature experience.

[0092] To fully illustrate the air conditioner control method, this invention also provides an embodiment, please refer to the appendix. Figure 6 .

[0093] Figure 6 This is a detailed flowchart of the steps of an air conditioner control method according to an embodiment of the present invention; as follows: Figure 6 As shown, the air conditioner control method includes the following steps S61-S69.

[0094] Step S61: Determine whether the outdoor unit is in heating mode; if yes, proceed to step S63; if not in heating mode, proceed to step S62, and defrosting is not required.

[0095] Step S63: Based on the first defrost sensor and the second defrost sensor, the temperature value T of the first outdoor unit heat exchanger is collected respectively. def1 Temperature data T of the second outdoor unit heat exchanger def2 .

[0096] Step S64, determine T def1 or T def2 First, reach the preset defrost temperature value T. def-tar .

[0097] If T def1 First, reach the preset defrost temperature value T. def-tar Then proceed to step S65:

[0098] Step S65: Set the first four-way valve to OFF, the second four-way valve to ON, the heating valve to OPEN, and the cooling valve to CLOSE.

[0099] In step S66, the heat exchanger of the first outdoor unit defrosts, while the indoor unit continues to heat.

[0100] If T def2 First, reach the preset defrost temperature value T. def-tar Then proceed to step S67:

[0101] Step S67: Set the first four-way valve to ON, the second four-way valve to OFF, the heating valve to OPEN, and the cooling valve to CLOSE.

[0102] In step S68, the second outdoor unit heat exchanger defrosts while the indoor unit continues to heat.

[0103] After step S66 or step S68 is completed, step S69 is executed to determine whether defrosting needs to continue.

[0104] If yes, return to step S63 and complete the alternating defrosting of the outdoor unit heat exchanger, then the defrosting process ends; otherwise, the defrosting process ends directly.

[0105] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the scope of protection of the present invention.
