Wherein, set up two outer fans, all open or all close or one opens another and closes through two outer fans, can provide abundanter heating and start switching mode and compound mode to guarantee the heating start-up effect and the air conditioner start-up high efficiency of air conditioner better.

Of course, the present solution is not limited to this illustration, and in other embodiments, the number of the external fans may be designed to be 3, 4, 5 or even more.

Switching through four-way valve 120 can be realized: in the heating mode, the discharge port of the compressor 110 communicates with the first heat exchanger 131 along the four-way valve 120, and the return port of the compressor 110 communicates with the second heat exchanger 132 along the four-way valve 120. In the cooling mode, a return port of the compressor 110 is communicated with the first heat exchanger 131 along the four-way valve 120, and a discharge port of the compressor 110 is communicated with the second heat exchanger 132 along the four-way valve 120. When the air conditioner is turned on, the four-way valve 120 mode can be roughly understood with reference to the heating mode.

The heating throttle 161 and the cooling throttle 162 are connected between the first heat exchanger 131 and the second heat exchanger 132, the heating throttle 161 is adapted to throttle the refrigerant flowing through the heating throttle 161 in the heating mode (when the air conditioner is cooling, the heating throttle 161 does not perform throttling function, i.e. one-way throttling, and is not throttled in the reverse direction), and the cooling throttle 162 is adapted to throttle the refrigerant flowing through the cooling throttle 162 in the cooling mode (when the air conditioner is heating, the cooling throttle 162 does not perform throttling function, i.e. one-way throttling, and is not throttled in the reverse direction).

More specifically, the air conditioner is provided with a first temperature measuring part 183 (specifically, for example, a temperature sensor such as a thermal resistor, an infrared thermometer, etc.), and the first temperature measuring part 183 is adapted to detect the outdoor ambient temperature T4. Of course, in other embodiments, the first thermometric element 183 may be configured to detect the indoor ambient temperature.

The outer tube 1321 is a part of the second heat exchanger 132, the air conditioner is provided with a third temperature measuring element 182 (specifically, for example, a temperature sensor, such as a thermal resistor, an infrared thermometer, etc.), and the third temperature measuring element 182 measures the temperature of the outer tube 1321 to obtain the temperature of the outer tube 1321.

Further, the air conditioner further has a first filter 151, the first filter 151 is connected between the second heat exchanger 132 and the heating throttle 161, and the second filter 152 is connected between the first heat exchanger 131 and the cooling throttle 162. The first filter 151 and/or the second filter 152 are disposed to prevent impurities from entering the throttling part, thereby ensuring the throttling effect of the air conditioner.

Further, the air conditioner further includes a gas-liquid separator 170, and the gas-liquid separator 170 is disposed between the four-way valve 120 and the compressor 110, and is configured to perform gas-liquid separation to prevent the compressor 110 from being fed with liquid.

The operation process of the air conditioner comprises the following steps:

when the air conditioner performs refrigeration, a high-temperature and high-pressure gas refrigerant discharged from the compressor 110 flows through the four-way valve 120, enters the condenser (i.e., the second heat exchanger 132) for heat dissipation, passes through the first filter 151, and then is throttled by the refrigeration throttling element 162 to form a low-temperature and low-pressure refrigerant, the refrigerant enters the indoor evaporator (i.e., the first heat exchanger 131) for heat absorption and evaporation, then flows into the vapor-liquid separator for vapor-liquid separation, a gaseous refrigerant returns to the compressor 110 for circulation, and a liquid refrigerant is stored in the vapor-liquid separator 170.

When the air conditioner heats, high-temperature and high-pressure gas refrigerant discharged from the compressor 110 flows through the four-way valve 120, enters the evaporator (i.e., the first heat exchanger 131) for heat dissipation, passes through the second filter 152, and then is throttled by the heating throttle 161 to form low-temperature and low-pressure refrigerant, the refrigerant enters the outdoor condenser (i.e., the second heat exchanger 132) for heat absorption and evaporation, then flows into the gas-liquid separator 170 for gas-liquid separation, the gas refrigerant returns to the compressor 110 for circulation, and the liquid refrigerant is stored in the gas-liquid separator 170.

The processor 210 of the air conditioner is electrically connected to the memory 220, the first temperature measuring unit 183, the first external fan 141 and the second external fan 142. As shown in fig. 4, the processor 210 is configured to execute the executable instructions stored in the memory 220 to implement the following steps:

and 404, controlling the air conditioner to start up according to the ambient temperature by using a first program or a second program, wherein the first program comprises a step of controlling all the external fans to operate, and the second program comprises a step of controlling at least one of the external fans to be turned off.

In some embodiments, the step of controlling the air conditioner to start according to the ambient temperature by using the first program or the second program specifically includes:

judging the magnitude relationship between the ambient temperature and a first preset threshold (for example, the first preset threshold is 18 ℃, although those skilled in the art will understand that the first preset threshold is usually selected to be a value in the range of 15 ℃ to 26 ℃);

if the ambient temperature is judged to be less than or equal to a first preset threshold value, controlling the air conditioner to start up according to a first program;

and if the ambient temperature is judged to be greater than the first preset threshold value, controlling the air conditioner to start up according to a second program.

When the ambient temperature is less than or equal to a first preset threshold value, the air conditioner heats at a non-high temperature, and the air conditioner runs through a plurality of outer fans, so that more heat can be discharged indoors in time while the load of pressure and inner pipe temperature is not too high, and the starting efficiency is improved.

When the ambient temperature is higher than a first preset threshold value, the air conditioner heats at high temperature, and at least one of the outer fans is closed, so that the risk of overhigh pressure or inner pipe temperature can be reduced, and the risk of starting failure or frequent starting caused by overhigh pressure or inner pipe temperature is reduced.

The control logic is simple by adopting a form of judging the relation between the ambient temperature and the first preset threshold value, the control method has the advantages of high response efficiency and high judgment accuracy, and the control accuracy and the control efficiency of the air conditioner can be improved.

In some embodiments, the air conditioner has a compressor 110 and an inner fan 143, and the compressor 110 and the inner fan 143 are electrically connected to the processor 210, respectively; wherein, the first program further comprises a step of controlling the compressor 110 to start and/or a step of controlling the internal fan 143 to start in a preset mode; the second program further includes a step of controlling the start of the compressor 110 and a step of controlling the start of the inner fan 143 in a preset mode.

Further, the preset mode includes a cold air prevention mode. The problem that cold wind blows people when can solving the start promotes the comfortable experience of product.

In some embodiments, the air conditioner has a second temperature measuring member 181, the second temperature measuring member 181 is configured to detect the temperature of the inner tube, and the second temperature measuring member 181 is electrically connected to the processor 210; wherein, the control of the inner fan 143 includes specifically in order to prevent the cold wind mode from starting: judging the size relationship between the temperature of the inner tube and a second preset threshold (the second preset threshold is specifically 20-28 ℃, and more specifically 24 ℃); if the temperature of the inner pipe is judged to be greater than or equal to the second preset threshold value, the inner fan 143 is controlled to start; and if the temperature of the inner pipe is judged to be less than the second preset threshold value, the inner fan 143 is controlled to be closed.

Like this, when the air conditioner starts based on first procedure and/or second procedure, interior fan 143 can make the air current temperature roughly about the second preset threshold value based on the anti-cold wind mode, can solve the problem that cold wind blows people when the start, promotes the comfortable experience of product.

In some embodiments, controlling the air conditioner to start in the second program specifically includes:

controlling the compressor 110 to start, and controlling one of the plurality of external fans to be turned off and another to be operated (specifically, for example, one of the first external fan 141 and the second external fan 142 is operated and the other is turned off);

judging whether pressure protection or temperature protection occurs;

if it is determined that pressure protection or temperature protection is present, the compressor 110 is controlled to start, and the state of a part of the external fans is controlled to be switched from operation to off (that is, for example, in the case of an air conditioner having two external fans, it can be understood that both of the two external fans are off, and in the case of an air conditioner having three or more external fans, it can be understood that the number of fans operating in the three or more external fans is reduced) or a plurality of external fans are controlled to be off;

judging whether pressure protection or temperature protection occurs again;

if it is determined that pressure protection or temperature protection occurs, the plurality of external fans are controlled to be turned off, and the compressor 110 is controlled to be started after the internal fan 143 is controlled to operate for a first preset time period (for example, the value range of the first preset time period is 5 seconds to 20 seconds, more specifically, the first preset time period is 10 seconds) at a preset wind speed threshold or a preset gear.

By the mode, the heat absorption capacity of the outer machine can be reduced and the heat dissipation capacity of the inner machine can be accelerated after the compressor 110 is started, so that the pressure or the temperature of the inner pipe can be reduced better, and the problem of starting failure caused by instant pressure protection can be avoided by a large program. Through the design of the second program, the temperature or the pressure of the inner pipe is gradually reduced layer by layer, the starting efficiency of the air conditioner is better considered while the starting success rate of the air conditioner is ensured, the misjudgment and miscontrol risks are reduced, and the control precision of the air conditioner is improved.

Further, based on the step of controlling the compressor 110 to start after controlling the inner fan 143 to operate for the first preset time at the preset wind speed threshold or the preset gear, after the compressor 110 operates for the second preset time (for example, the value of the second preset time ranges from 0.5 minutes to 5 minutes, and more specifically, the second preset time is 3 seconds): controlling a plurality of external fans to start according to the ambient temperature by a first program or a second program; and/or control the internal fan 143 to start in a preset mode. Therefore, the heating starting operation of the air conditioner is more reliable, and the starting failure frequency and the risk of frequent starting are lower.

Further, based on the step of determining or re-determining whether pressure protection or temperature protection is present, if it is determined that pressure protection or temperature protection is not present, the inner fan 143 is controlled to start in the preset mode. By the method, the starting failure rate of the compressor 110 is reduced while the cold air starting is prevented by the overheating load of the air conditioner, and the problem of frequent starting of the compressor 110 is well solved, so that the problems of noise and the like caused by frequent starting of the compressor 110 are well solved.

In some embodiments, the air conditioner further includes a detection component electrically connected to the processor 210.

For example, the detection means particularly comprises a pressure detection element adapted to detect the exhaust pressure or a second temperature measuring element 181 adapted to detect the temperature of the inner tube.

More specifically, for example, in the case where the detection means includes a pressure detection element, the pressure detection element may be embodied as a pressure sensor, a pressure switch, or the like, and the pressure detection element may be embodied as a high-pressure switch that is provided on the exhaust pipe and detects the pressure at the exhaust pipe and feeds back the detection result to the processor 210. For example, when the high pressure switch is turned off (it can be understood that when the exhaust pressure reaches a third preset threshold, the high pressure switch is turned off, and a person skilled in the art can flexibly design the third preset threshold based on the specific pressure protection requirement, and the third preset threshold is not specifically limited herein), it indicates that pressure protection is present, and the determination result is fed back to the processor 210. Further, the pressure detecting element may further include a low pressure switch disposed on the muffler and adapted to detect a pressure at the muffler.

In the case where the detection means includes the second temperature measuring member 181, the second temperature measuring member 181 can detect the temperature of the indoor unit or the inner tube 1311 of the indoor portion, for example, a part of the first heat exchanger 131 is the inner tube 1311, and the second temperature measuring member 181 measures the temperature of the inner tube 1311 of the first heat exchanger 131 to obtain the temperature of the inner tube. If the temperature of the inner tube is greater than or equal to a fourth preset threshold (specifically, the fourth preset threshold is a value within a range of 55 ℃ to 65 ℃, or more specifically, the fourth preset threshold is 60 ℃. it can be understood that a person skilled in the art can flexibly design the fourth preset threshold based on a specific pressure protection requirement, and does not specifically limit the fourth preset threshold), it indicates that temperature protection is occurring, and the determination result is fed back to the processor 210.

And if the exhaust pressure is judged not to reach the third preset threshold value or the temperature of the inner pipe is judged to be lower than the fourth preset threshold value, judging that pressure protection or temperature protection does not occur.

Through the scheme, the exhaust overpressure or overheating of the air conditioner is reflected more directly, so that the control logic is simplified, and the control precision and the response efficiency are improved.

In some embodiments, the compressor 110 of the air conditioner is a fixed frequency air conditioner, and the air conditioner is a fixed frequency air conditioner accordingly.

As shown in fig. 4, a control method of an air conditioner according to an embodiment of the present invention is used for controlling the air conditioner described in any of the above embodiments, and the control method includes the following steps:

step 402, controlling the air conditioner to start up in a heating mode;

It is to be understood that the air conditioner for controlling the air conditioner control method can be understood by referring to the content of any one of the above embodiments, and will not be repeated here.

In some embodiments, as shown in fig. 5, the step of controlling the air conditioner to start according to the ambient temperature by a first program or a second program specifically includes:

step 502, determining the relationship between the ambient temperature T4 and a first preset threshold Tw 1;

step 5042, if T4 is not greater than Tw1, controlling the air conditioner to start according to a first program;

in step 5044, if T4 is greater than Tw1, the air conditioner is controlled to start according to the second program.

In some embodiments, the ambient temperature T4 is specifically an outdoor ambient temperature, and the first predetermined threshold Tw1 is typically a value in the range of 15 ℃ to 26 ℃.

When T4 is not more than Tw1, the air conditioner is not heated at high temperature, and the plurality of outer fans are operated, so that the pressure and the inner pipe temperature are not too high, more heat can be discharged indoors in time, and the starting efficiency is improved.

When T4 is more than Tw1, the air conditioner heats at high temperature, and at least one of the external fans is closed, so that the risk of overhigh pressure or internal pipe temperature can be reduced, and the risk of starting failure or frequent starting caused by overhigh pressure or internal pipe temperature is reduced.

The form of judging the relation between the ambient temperature and the first preset threshold value is adopted, so that the control logic is simple, the advantages of high response efficiency and high judgment accuracy are achieved, and the control accuracy and efficiency of the air conditioner can be improved.

In some embodiments, the first program further comprises the step of controlling the start of the compressor and/or the step of controlling the start of the internal blower in a preset mode; the second program further includes a step of controlling the start of the compressor and a step of controlling the start of the inner fan in a preset mode.

Further by way of example, the preset mode includes a cold air prevention mode. The problem that cold wind blows people when can solving the start promotes the comfortable experience of product.

Specifically, for example, as shown in fig. 6, controlling the air conditioner to start according to the first program specifically includes:

step 602, after the compressor is controlled to be started, controlling the plurality of external fans to operate (specifically, controlling the first external fan and the second external fan to operate).

According to the requirement, after step 602, the internal blower can be further controlled to start in a preset mode.

In some embodiments, controlling the internal blower to start in the cold-air prevention mode specifically includes:

judging the size relationship between the temperature of the inner pipe and a second preset threshold (the second preset threshold is specifically 20-28 ℃, and more specifically 24 ℃);

if the temperature of the inner pipe is judged to be greater than or equal to a second preset threshold value, controlling the inner fan to start;

and if the temperature of the inner pipe is judged to be less than the second preset threshold value, controlling the inner fan to be closed.

Like this, when the air conditioner starts based on first procedure and/or second procedure, interior fan can make the air current temperature roughly about the second preset threshold value based on prevent cold wind mode, can solve the problem that cold wind blows people when the start, promotes the comfortable experience of product.

In some embodiments, as shown in fig. 7, controlling the air conditioner to start according to the second program specifically includes:

step 702, controlling a compressor to start, controlling one part of a plurality of external fans to be closed, and controlling the other part to run;

if yes, go to step 708; if not, go to step 706;

step 708, controlling the compressor to start and controlling the plurality of external fans to be closed;

step 706, controlling the internal fan to start in a preset mode;

step 710, judging whether pressure protection or temperature protection occurs;

if yes, go to step 712; if not, go to step 706;

step 712, controlling the inner fan to operate at a preset gear (specifically, if the inner fan is controlled to operate at a low windshield, of course, the inner fan may also operate at a rotation speed of a set low wind speed threshold according to a requirement, and a person skilled in the art may flexibly design the preset gear and the preset rotation speed threshold according to a specific requirement, which is not particularly limited herein), and then controlling the compressor to start after a first preset duration;

and 714, after the compressor runs for a second preset time, controlling the inner fan to start in a preset mode (such as a cold air prevention mode), and controlling the plurality of outer fans to start in the first program or the second program according to the ambient temperature.

Further for example, controlling the plurality of external fans to start according to the first program or the second program specifically includes:

detecting an ambient temperature T4;

if T4 is not less than Tw1, controlling the plurality of external fans to operate (i.e. controlling the first external fan and the second external fan to operate);

if T4 > Tw1, one part of the outer fans is controlled to be operated, and the other part is controlled to be closed (for example, one of the first outer fan and the second outer fan is controlled to be operated, and the other is controlled to be closed).

By the mode, the heat absorption capacity of the outer machine can be reduced and the heat dissipation capacity of the inner machine can be accelerated after the compressor is started, so that the pressure or the temperature of the inner pipe can be reduced better, and the problem of starting failure caused by instant pressure protection can be avoided by a large program. Through the design of the second program, the temperature or the pressure of the inner pipe is gradually reduced layer by layer, the starting efficiency of the air conditioner is better considered while the starting success rate of the air conditioner is ensured, the misjudgment and miscontrol risks are reduced, and the control precision of the air conditioner is improved. And through the design, the failure rate of the compressor starting is reduced, and the problem of frequent starting of the compressor is well solved, so that the problems of noise and the like caused by frequent starting of the compressor are better avoided.

Further, the step of determining or determining again whether pressure protection or temperature protection occurs (e.g., step 704 or step 710) specifically includes:

judging the magnitude relation between the exhaust pressure and a third preset threshold (the third preset threshold can be flexibly designed by a person skilled in the art based on specific pressure protection requirements and is not specifically limited herein) or the magnitude relation between the inner pipe temperature and a fourth preset threshold (the fourth preset threshold can be flexibly designed by the person skilled in the art based on specific temperature protection requirements and is not specifically limited herein);

if the exhaust pressure is judged to reach a third preset threshold or the temperature of the inner pipe is larger than or equal to a fourth preset threshold, judging that pressure protection or temperature protection occurs;

As shown in fig. 8, an embodiment of the present invention provides a control method of an air conditioner, including the steps of:

step 801, heating and starting up;

step 802, detecting an ambient temperature T4;

in step 8042, if it is determined that Tw1(Tw1 is, for example, 18 ℃) < T4, then step 8062 is executed;

step 8044, if T4 is judged to be not more than Tw1, executing step 8064;

step 8064, after the compressor is started, the two outer fans are turned on (for example, both the first outer fan and the second outer fan are turned on);

8062, after the compressor is started, the single outdoor unit fan is turned on (for example, one of the first outdoor unit fan and the second outdoor unit fan is turned on);

step 808, judging whether pressure protection or temperature protection occurs;

if yes, go to step 810, otherwise go to step 812;

step 810, turning off the outer machine double fans (for example, turning off both the first outer fan and the second outer fan), and starting the compressor;

step 812, controlling the internal fan to start in a preset mode (such as a cold air prevention mode);

step 814, judging whether pressure protection or temperature protection occurs;

if yes, go to step 816, otherwise go to step 812;

In the scheme, when T4 is detected to be not less than Tw1, it is indicated that an outdoor unit (i.e., an outdoor unit or an outdoor side part) of the air conditioner is not high in ambient temperature and belongs to non-high-temperature heating, and the heat absorption capacity of a refrigerant can be improved by controlling the starting of the outdoor unit fans (i.e., the first outdoor fan and the second outdoor fan), so that the step 8064 is designed, and after the compressor is started, the outdoor unit fans are started.

When Tw1< T4 is detected, it indicates that the outdoor unit (i.e. the outdoor unit or the outdoor side unit) of the air conditioner is in a high-temperature environment, and the outdoor unit belongs to high-temperature heating. And then judging whether the air conditioner has high-pressure protection (namely pressure protection) or high-temperature protection (temperature protection) shutdown, if not, starting the internal unit according to a cold wind prevention program, if so, controlling the double fans of the external unit to be closed, then starting the compressor, and then judging whether the air conditioner has high-pressure protection or high-temperature protection shutdown. In the second judgment, if the judgment result is negative, the internal machine is started according to the cold wind prevention program, if the judgment result is positive, the double fans of the external machine are controlled to be closed, the internal machine is started at low wind, the compressor is started again after 10 seconds, after the compressor is started to run for 3 minutes, the windshield of the internal machine runs according to the cold wind prevention program, and the fan of the external machine is controlled to be started and closed according to a preset program (namely, a second program).

The control method for the air conditioner provided by the embodiment has the advantages that the compressor can be smoothly started when the air conditioner is overloaded during heating, the starting failure rate of the compressor is low, frequent starting and stopping of the compressor are avoided, noise influence is reduced, the compressor can reliably operate, and the first outer fan, the second outer fan and the inner fan can more reliably operate.
