DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below: The compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.

[0031] In view of the above technical problems existing in the related art, the embodiment of the present application provides a startup control method based on variable splitting, such as Figure 1As shown in the figure, a flow divider connected to the throttling unit can be an integrated structure with the throttling unit or a split structure. When the supercooling degree of the air conditioner is low, the supercooling degree of the air conditioner can be improved by adjusting the flow diversion mode of the flow divider. The adjustment mode includes: adjusting from single-way diversion to double-way diversion, or adjusting from double-way diversion to single-way diversion. Based on Figure 3 ,like Figure 4 As shown, the two shunt pipes (including pipe A and pipe B) of the shunt can be connected to the two pipes on the outdoor heat exchanger respectively, so that the shunt mode can be adjusted. The startup control method based on variable shunt provided in the embodiment of the present application determines whether the shunt needs to be adjusted according to the user setting and the current ambient temperature when the machine is first started, and makes a series of changes, thereby quickly meeting the needs of the user.

[0032] The power-on start-up control method based on variable split provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0033] like Figure 3 As shown, an embodiment of the present application provides a startup control method based on variable splitting, which may include the following steps 301 and 302: Step 301: After the air conditioner is powered on, the current operating mode and set temperature of the air conditioner are obtained.

[0034] Exemplarily, the above-mentioned set temperature is mainly used for calculating the reference control parameter, which is the main judgment basis of the control method in the embodiment of the present application. The reference control parameter will change with the change of the current ambient temperature.

[0035] Step 302: Based on the set temperature and the current ambient temperature, the startup process of the air conditioner in different operating modes is controlled by using different diversion modes of the diverter until the air conditioner is completely started.

[0036] The diversion modes of the diverter include: single-way diversion and double-way diversion; one end of the diverter is connected to the throttling unit, and the other end is connected to the heat exchanger on the outdoor unit.

[0037] Exemplarily, in the embodiment of the present application, different control methods can be adopted for the heating mode and the heating mode. During the control process, reference control parameters need to be used as the main judgment basis.

[0038] Specifically, in the above step 302, the calculation of the reference control parameter may further include the following steps 302a: Step 302a, calculating the absolute value of the difference between the set temperature and the current ambient temperature to obtain a calculation result, and multiplying the calculation result by the amplification factor to obtain a reference control parameter.

[0039] Exemplarily, the reference control parameter Pn=|set temperature-ambient temperature|*amplification factor, and the amplification factor may be a natural number greater than 1, such as 5, 9, 10, etc.

[0040] Exemplarily, in an embodiment of the present application, for control in cooling mode, the reference control parameter can be divided into intervals, divided into three different intervals (i.e., a first interval, a second interval, and a third interval), and different control methods can be adopted for reference control parameters in different intervals.

[0041] Specifically, for the case where the reference control parameter is in the first interval, the above step 302 may further include the following steps 302b1 and 302b2: Step 302b1: When the current operating mode of the air conditioner is the cooling mode, if the reference control parameter is greater than or equal to a first preset threshold, the operation of the air conditioner is controlled with the maximum operating frequency of the compressor in the cooling mode, and during the operation, it is determined whether the power of the air conditioner exceeds the preset power threshold.

[0042] Step 302b2: When the power of the air conditioner exceeds the preset power threshold, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion, and after the reference control parameter is less than the second preset threshold and lasts for a first preset time, the diversion mode of the diverter is adjusted from multi-way diversion to single-way diversion.

[0043] Wherein, when the air conditioner operates at the maximum operating frequency of the compressor in the cooling mode, the diversion method of the diversion is single-way diversion.

[0044] For example, Figure 4 As shown, in cooling mode, if Pn≥50 (i.e., the first preset threshold), the compressor is controlled to operate at the maximum operating frequency in cooling mode, and it is determined whether the operating power of the air conditioner exceeds the set value (i.e., the preset power threshold). If the operating power of the air conditioner exceeds the set value, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion. Afterwards, when Pn<20 and lasts for 30s (i.e., the first preset duration), single-way diversion is used instead.

[0045] Specifically, for the case where the reference control parameter is in the second interval, the above step 302 may further include the following steps 302c1 and 302c2: Step 302c1. When the current operating mode of the air conditioner is the cooling mode, if the reference control parameter is greater than or equal to the second preset threshold and less than the first preset threshold, the operation of the air conditioner is controlled with the maximum operating frequency of the compressor in the cooling mode, and during the operation, it is determined whether the reference control parameter is less than the second preset threshold.

[0046] Step 302c2: When the reference control parameter is less than the second preset threshold value and the operating time of the air conditioner is less than the second preset time, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion; and after the reference control parameter is less than the second preset threshold value and lasts for a first preset time, the diversion mode of the diverter is adjusted from multi-way diversion to single-way diversion.

[0047] Wherein, when the air conditioner operates at the maximum operating frequency of the compressor in the cooling mode, the diversion method of the diversion is single-way diversion.

[0048] For example, Figure 4 As shown, in cooling mode, if 20≤Pn<50, the compressor is controlled to run at the maximum operating frequency in cooling mode, and it is determined that the air conditioner meets Pn<20 (i.e., the second preset threshold) within 5 minutes (i.e., the second preset time length). If so, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion. Afterwards, when Pn<20 and lasts for 30 seconds (i.e., the first preset time length), single-way diversion is used instead.

[0049] Specifically, for the case where the reference control parameter is in the third interval, the above step 302 may further include the following steps 302d1 and 302d2: Step 302d1: When the current operating mode of the air conditioner is the cooling mode, if the reference control parameter is less than a second preset threshold value, the operation of the air conditioner is controlled at a preset percentage of the maximum operating frequency of the compressor in the cooling mode, and during the operation, it is determined whether the current ambient temperature meets the standard.

[0050] Step 302d2: When the current ambient temperature is less than or equal to the set temperature, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion.

[0051] Wherein, when the air conditioner operates at a preset percentage of the maximum operating frequency of the compressor in the cooling mode, the diversion method of the diversion is single-way diversion.

[0052] Exemplarily, in cooling mode, if Pn<20, the compressor is controlled to operate at 70% of the maximum operating frequency in cooling mode (i.e., the above-mentioned preset percentage), and the diversion mode of the diverter is single-way diversion operation. After that, when the indoor ambient temperature reaches the standard, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion.

[0053] Exemplarily, in an embodiment of the present application, for control in the heating mode, the reference control parameter can be divided into intervals, divided into three different intervals (i.e., the fourth interval, the fifth interval, and the sixth interval), and different control methods can be adopted for the reference control parameters in different intervals.

[0054] Specifically, for the case where the reference control parameter is in the fourth interval, the above step 302 may further include the following steps 302e1 and 302e2: Step 302e1. When the current operating mode of the air conditioner is the heating mode, if the reference control parameter is greater than or equal to the third preset threshold, the operation of the air conditioner is controlled at the maximum operating frequency of the compressor in the heating mode, and during the operation, it is determined whether the reference control parameter is between the third preset threshold and the fourth preset threshold.

[0055] Step 302e2: When the reference control parameter is between the third preset threshold and the fourth preset threshold and the operating time of the air conditioner is less than the third preset time, the diversion mode of the diverter is adjusted from multi-way diversion to single-way diversion; and after the reference control parameter is less than the fourth preset threshold and lasts for a fourth preset time, the diversion mode of the diverter is adjusted from single-way diversion to multi-way diversion.

[0056] Wherein, when the air conditioner operates at the maximum operating frequency of the compressor in the heating mode, the diversion method of the diversion is multi-way diversion.

[0057] For example, Figure 4 As shown, in the heating mode, if Pn≥60 (i.e., the third preset threshold value mentioned above), the compressor of the air conditioner is controlled to run at the maximum operating frequency in the heating mode. Afterwards, if 30≤Pn<60 is satisfied within 5 minutes (i.e., the third preset duration mentioned above), the diversion mode of the diverter is adjusted from multi-way diversion to single-way diversion. Finally, when Pn<30 (i.e., the fourth preset threshold value mentioned above) and lasts for 30 seconds (i.e., the fourth preset duration mentioned above), multi-way diversion is used instead.

[0058] Specifically, for the case where the reference control parameter is in the fifth interval, the above step 302 may further include the following steps 302f1 and 302f2: Step 302f1, when the current operating mode of the air conditioner is the heating mode, if the reference control parameter is less than the third preset threshold and greater than or equal to the fourth preset threshold, the operation of the air conditioner is controlled with the maximum operating frequency of the compressor in the heating mode, and during the operation, it is determined whether the reference control parameter is less than the fourth preset threshold.

[0059] Step 302f2: When the reference control parameter is less than the fourth preset threshold value and the operation time of the air conditioner is greater than the fourth preset time, the diversion mode of the diverter is adjusted from multi-way diversion to single-way diversion.

[0060] Wherein, when the air conditioner operates at the maximum operating frequency of the compressor in the heating mode, the diversion method of the diversion is multi-way diversion.

[0061] For example, Figure 4 As shown, in the heating mode, if 30≤Pn<60, the compressor of the air conditioner is controlled to operate at the maximum operating frequency in the heating mode. Afterwards, when Pn<30 and lasts for 30s, multi-way splitting is used instead.

[0062] Specifically, when the reference control parameter is in the sixth interval, the above step 302 may further include the following step 302g: Step 302g: When the current operating mode of the air conditioner is the heating mode, if the reference control parameter is less than a fourth preset threshold, the operating frequency of the compressor is adjusted using a preset proportional, integral, and differential (PID) control method, and the diverter is controlled to adopt a multi-path diversion method.

[0063] For example, Figure 4 As shown, in heating mode, if Pn < 30, it directly enters PID regulation and selects multi-way diversion.

[0064] The power-on start-up control method based on variable shunt provided in the embodiment of the present application first obtains the current operation mode and set temperature of the air conditioner after the air conditioner is powered on; then, based on the set temperature and the current ambient temperature, controls the start-up process of the air conditioner under different operation modes using different shunt modes of the shunt until the air conditioner is completely started; wherein the shunt modes of the shunt include: single-way shunt and double-way shunt; one end of the shunt is connected to the throttling unit, and the other end is connected to the heat exchanger on the outdoor unit.
