technical field

The use of household air conditioners and central air conditioners is becoming more and more common. Users have higher and higher requirements for the comfort of air conditioners. The problems of the air conditioner are gradually exposed, one of which is the condensation problem of the air conditioner evaporator and the air duct.

The reasons for the condensation of the air conditioner are as follows: (1) The air humidity in the air conditioning area is relatively high; (2) Due to the unreasonable setting of the new exhaust system in the air conditioning area, excessive negative pressure is generated, which makes the outdoor air (3) The air conditioner itself uses a large temperature difference to supply air, but the air supply volume and cooling capacity of the machine itself are not equipped, resulting in excessive cooling capacity and too small air volume; ( 4) The air outlet is made of aluminum material. Due to its good thermal conductivity, the surface temperature of the air outlet material is too low to condense dew.

Especially for air conditioners operating in high-temperature and high-humidity environments, when the operation time is too long, condensation water droplets will appear on the guide plates and panels, and a large amount of condensation water will also appear on the evaporator, which will occur when the air conditioner supplies air to the room. Blowing and dripping of water occurred, which affected the user experience, so the condensation problem of the air conditioner needs to be solved urgently.

Embodiment (1)

Fig. 1 is a schematic flow diagram showing the anti-condensation air conditioning control method of the present invention according to embodiment (1).

As shown in Figure 1, the present invention provides an anti-condensation air conditioning control method; specifically, the process steps of the control method mainly include:

S101. Obtain first operating parameters of the air conditioner, where the first operating parameters at least include: internal fan speed, first indoor temperature, first indoor humidity, and first internal coil temperature;

In this embodiment, the first operating parameter can be detected by a plurality of different types of sensors, or obtained directly or indirectly from the operating data of the air conditioner itself;

For example, the internal fan of the air conditioner is driven by the electric energy supplied by the air conditioner. The actual speed of the internal fan is mainly affected by its current operating voltage and/or operating current, that is, the parameter of the internal fan speed is related to the operating voltage and/or The working current has a certain relationship. Therefore, by obtaining the operating data such as the current working voltage and/or working current of the internal fan, the current speed of the internal fan can be obtained by further combining the above-mentioned relationship;

The indoor unit of the air conditioner is equipped with a temperature sensor, and the temperature sensor can be used to detect the current temperature parameter of the indoor environment. In step S101, the current temperature parameter detected by the temperature sensor can be obtained and used as the first indoor temperature;

Similarly, the indoor unit of the air conditioner is equipped with a humidity sensor. The humidity sensor can be used to detect the current humidity parameter of the indoor environment. In step S101, the current humidity parameter detected by the humidity sensor can be obtained and used as the first indoor humidity;

Similarly, the indoor unit of the air conditioner is also equipped with another temperature sensor at the inner coil, which can be used to detect the current temperature parameter of the inner coil, and the current temperature parameter detected by the temperature sensor can be obtained in step S101 , and as the first inner coil temperature;

S102. Based on the first operating parameter, determine whether the air conditioner meets the first anti-condensation condition;

In this embodiment, the first anti-condensation condition is used to determine whether there is or will be condensation under the current operating conditions of the air conditioner; Condensation; and when the air conditioner does not meet the first anti-condensation condition, it is determined that the air conditioner does not exist or does not produce condensation. In this way, based on the first operating parameters and the judgment of the first anti-condensation condition, further determination can be made Subsequent operation of the air conditioner;

In this embodiment, the first anti-condensation condition includes at least the first rotational speed condition, the first humidity condition, the first inner coil temperature condition and the first duration condition, that is, whether the air conditioner in the present invention already exists or will produce condensation The condition judgment of the condensation problem is a comprehensive judgment based on the internal fan speed, temperature, humidity and operating time, etc., which can improve the accuracy of the judgment of the condensation problem of the air conditioner and avoid misjudgment problems caused by abnormal individual parameters;

Specifically, under the first speed condition, the speed of the internal fan is at a low wind speed gear; here, for existing types of air-conditioning products, the speed of the internal fan of the air conditioner is generally divided into multiple different gears, for example, a gear The division method is low wind speed gear, medium wind speed gear and high wind speed gear. Each gear corresponds to a speed value or speed range value. As the gear increases, the specific speed value or speed range value The value also increases accordingly; the first speed condition of the present invention is based on judging whether the current internal fan speed gear is in the low wind speed gear, if yes, then the first speed condition is satisfied; if not, then no meeting the first rotational speed condition;

Here, the advantage of introducing the parameter of the speed of the indoor fan into the judgment of the condensation problem of the air conditioner is that when the air conditioner is running at a lower speed, the speed of the indoor air flowing through the indoor unit is relatively low, and the time it stays inside the indoor unit is relatively low. Longer, so that the moisture in the indoor air can have sufficient time to condense into dew on the indoor heat exchanger. Therefore, when the speed of the internal fan is low, condensation may occur in the air conditioner.

The first humidity condition, the first indoor humidity is greater than the first humidity threshold; the first humidity threshold is used to characterize the indoor humidity, and the first indoor humidity generally takes a relatively large value, such as relative humidity 80%, relative humidity 90% %, etc.; here, when the indoor humidity is greater than the first humidity threshold, it means that the indoor humidity in the current indoor environment is relatively high, and the water vapor content is relatively high; when the indoor humidity is not greater than the first humidity threshold, it means that the current indoor environment The indoor humidity in the environment is low, and the water vapor content is low.

Here, the greater the indoor humidity, the more moisture will be mixed in the indoor air. When the indoor air flows through the indoor unit of the air conditioner, the more water vapor will easily condense into dew; It may cause condensation problems in the air conditioner.

The temperature condition of the first inner coil, the temperature of the first inner coil satisfies the following relationship:

The first inner coil temperature<A*first indoor temperature+B*first indoor humidity-C, where A and B are calculation coefficients, and C is a calculation constant;

The lower the temperature of the inner coil, the more dew will condense when the water vapor flows through the indoor unit. The above "A*first indoor temperature+B*first indoor humidity-C" is used to indicate that the inner coil is easy to condense dew When the current internal coil temperature is lower than this temperature limit, the low temperature environment of the internal coil will easily condense the water vapor in the indoor air flowing through it into dew; if the current internal coil temperature is not lower than this temperature limit When the temperature limit is lower, the amount of dew condensation caused by the low temperature environment of the inner coil is less;

Optionally, the value of the calculation coefficient A is 0.95, the value of the calculation coefficient B is 0.26, and the calculation coefficient of the calculation constant C is 38.4.

The first duration condition, the cumulative duration of the air conditioner meeting the first speed condition, the first humidity condition and the first inner coil temperature condition is greater than the first duration;

In this embodiment, if the accumulative time for the air conditioner to meet the first rotational speed condition, the first humidity condition, and the first inner coil temperature condition is relatively short, such as only for 1 minute, 2 minutes, etc., the actual condensation amount of the air conditioner is relatively short. less, it can be ignored. In the case of a long duration, the air conditioner is very prone to condensation problems. Therefore, the first anti-condensation condition of the present invention also includes the first duration condition to reduce misjudgments caused by temperature and humidity fluctuations in a short period of time. And other issues.

Optionally, the value of the first duration is 1 hour;

S103. In response to the air conditioner meeting the first anti-condensation condition, control the air conditioner to perform a preset first anti-condensation operation.

The anti-condensation air conditioner control method provided by the present invention can accurately judge whether the current operating state and environmental conditions of the air conditioner may have caused the air conditioner to generate condensation by collecting various first operating parameters and making judgments in combination with preset anti-condensation conditions. Condensation problems, and timely implementation of preset anti-condensation operations to reduce the occurrence of air-conditioning condensation problems and improve user experience.

Optionally, for fixed-frequency air-conditioning products, since the operating frequency of the compressor cannot be adjusted, the first anti-condensation operation performed by the air-conditioner in step S103 includes: controlling to increase the speed of the internal fan of the air-conditioner to the first - set speed.

Here, the first set rotational speed is a rotational speed higher than the low wind speed gear, such as the middle wind speed gear or the high wind speed gear.

Alternatively, based on the low wind speed gear, the speed of the internal fan is increased by a set speed value, for example, by 30rpm, the adjusted speed of the internal fan is R+30, where R refers to the low wind speed gear.

Fig. 2 is a second schematic flow diagram of the air-conditioning control method for anti-condensation according to the embodiment (1) of the present invention.

In an optional embodiment, after the air conditioner performs the preset first anti-condensation operation, the actual operating parameters of the air conditioner are different from those during normal operation of the air conditioner, so that the actual outlet temperature of the air conditioner will also Changes occur, in order to shorten the occupation time of the first anti-condensation operation, so that the air conditioner can return to the initial operating state as soon as possible; the control method of the present invention also includes a judgment and control step for exiting the first anti-condensation operation; specifically, as As shown in Fig. 2, another anti-condensation air conditioning control method of the present invention includes:

S201. Obtain the first operating parameter of the air conditioner;

In this embodiment, the specific implementation process of step S201 can refer to the aforementioned step S101, which will not be repeated here;

S202. Based on the first operating parameter, determine whether the air conditioner satisfies the first anti-condensation condition;

In this embodiment, the specific implementation process of step S202 can refer to the aforementioned step S102, which will not be repeated here;

S203. In response to the air conditioner meeting the first anti-condensation condition, control the air conditioner to perform a preset first anti-condensation operation;

In this embodiment, the specific implementation process of step S203 can refer to the aforementioned step S103, which will not be repeated here;

S204. Obtain second operating parameters when the air conditioner performs the first anti-condensation operation, where the second operating parameters include one or more of the following parameters: second indoor temperature, second indoor humidity, and second inner coil temperature;

In this embodiment, the acquisition method of the second operating parameter in step S204 can refer to step S101, which will not be described in detail here;

Here, based on the specific type and quantity of exit conditions in step S205, the type and quantity of the second operating parameters to be acquired in step S204 can be predetermined. If the exit conditions only include the second humidity condition, step S204 only obtains the second humidity condition The single parameter of the second indoor humidity; or, if the exit condition only includes the second inner coil temperature condition, then the three parameters of the second indoor temperature, the second indoor humidity and the second inner coil temperature need to be obtained respectively;

S205. Based on the second operating parameter, determine whether the air conditioner satisfies the exit condition, and the exit condition includes one or more of the following conditions:

The second humidity condition is that the humidity in the second room is not greater than the first humidity threshold; here, when the humidity in the second room is not greater than the first indoor threshold, it means that the humidity in the indoor environment is low at this time, and the water vapor content in the indoor air is relatively low. less, the indoor air flowing through the indoor unit will condense less dew in the indoor unit, and the air conditioner is not prone to condensation problems;

The temperature condition of the second inner coil, the temperature of the second inner coil satisfies the following relationship:

The temperature of the second inner coil ≥ A*second indoor temperature+B*second indoor humidity-C;

Here, when the second inner coil temperature condition is satisfied, it means that the temperature condition of the inner coil at this time is not easy to cause dew condensation on it, and the amount of condensation produced by the air conditioner is less.

S206. In response to the air conditioner meeting the exit condition, control the air conditioner to exit the first anti-condensation operation.

Here, after the air conditioner quits the first anti-condensation operation, it can be switched to the operating state before the first anti-condensation operation to continue running.

Optionally, in step S102, if the air conditioner only satisfies the first speed condition but does not meet the first humidity condition and the first inner coil temperature condition, although the speed of the internal fan of the air conditioner is relatively low at this time, the current indoor Conditions such as the ambient humidity and the temperature of the inner coil are unlikely to cause condensation on the indoor unit, so the first consumption reduction operation is controlled to reduce the energy consumption of the air conditioner through the first consumption reduction operation.

In an optional embodiment, the first consumption reduction operation includes: controlling to reduce the speed of the internal fan of the air conditioner to the second set speed.

Here, the second set speed is the speed value lower than the current actual speed in the low wind speed gear. For example, the speed range corresponding to the low wind speed gear of a type of air conditioner is 0-60rpm/min. When the first speed condition does not meet the first humidity condition and the first inner coil temperature condition, the current actual speed of the air conditioner is 50rpm/min, and the second set speed is a speed value lower than 50rpm/min, such as 40rpm/min. min, 30rpm/min, etc.

Here, the "A*first indoor temperature+B*first indoor humidity-C" used in the second inner coil temperature price adjustment is consistent with that in step S302; when the second inner coil temperature condition is satisfied, it indicates that the current inner The temperature of the coil makes it easier for dew to condense in the indoor unit, and the implementation of the first anti-condensation operation has not effectively improved the condensation problem;

S306. In response to the air conditioner meeting the second anti-condensation condition, control the air conditioner to perform a preset second anti-condensation operation.

Optionally, for a fixed-frequency air conditioner, since the operating frequency of the compressor cannot be adjusted, the second anti-condensation operation performed by the air conditioner in step S306 includes: controlling the compressor of the air conditioner to stop. In this way, the low-temperature refrigerant can no longer continue to be input into the indoor unit. Affected by the room temperature, the temperature of the inner coil gradually rises, which no longer satisfies the low temperature condition where dew is easy to condense, so that the dew condensation is reduced; at the same time, the condensed dew is also reduced. It can gradually evaporate under the influence of indoor temperature, so that the amount of dew water in the indoor unit can be gradually reduced.

Here, the third operating parameter includes one or more of the following parameters: the third indoor temperature, the third indoor humidity, and the third inner coil temperature; in this embodiment, the third operating parameter in step S404 can be acquired by Referring to step S401, details are not repeated here;

Here, based on the specific type and quantity of exit conditions in step S405, the type and quantity of the third operating parameters to be acquired in step S404 can be predetermined. If the exit conditions only include the second humidity condition, step S404 only obtains the second humidity condition. The single parameter of humidity in the third room; or, if the exit condition only includes the temperature condition of the third inner coil, it is necessary to obtain the three parameters of the third room temperature, the third room humidity and the third inner coil temperature respectively;

S405. Based on the third operating parameter, determine whether the air conditioner satisfies the exit condition;

Exit conditions include one or more of the following conditions: the third humidity condition and the third inner coil temperature condition;

Among them, the third humidity condition is that the humidity in the third room is not greater than the first humidity threshold; here, when the humidity in the third room is not greater than the first indoor threshold, it means that the humidity in the indoor environment is low at this time, and the water vapor in the indoor air With less content, the indoor air flowing through the indoor unit will condense less dew in the indoor unit, and the air conditioner will not easily produce condensation problems;

The temperature condition of the third inner coil, the temperature of the third inner coil satisfies the following relationship: the temperature of the third inner coil ≥ A*the third indoor temperature+B*the third indoor humidity-C; here, when the third inner coil is satisfied When the temperature condition of the inner coil is low, it means that the temperature of the inner coil at this time is not easy to cause dew to condense on it, and the amount of condensation produced by the air conditioner is small;

When the first speed condition does not meet the first humidity condition and the first inner coil temperature condition, the current actual speed of the air conditioner is 50rpm/min, and the second set speed is a speed value lower than 50rpm/min, such as 40rpm/min. min, 30rpm/min, etc.

Embodiment (three)

Fig. 5 is a first schematic flow diagram showing the anti-condensation air conditioning control method of the present invention according to the third embodiment.

As shown in Figure 5, the present invention provides another anti-condensation air conditioning control method; specifically, the process steps of the control method mainly include:

S501. Obtain first operating parameters of the air conditioner, where the first operating parameters at least include: internal fan speed, first indoor temperature, first indoor humidity, and first internal coil temperature;

In this embodiment, the first operating parameter can be detected by a plurality of different types of sensors, or obtained directly or indirectly from the operating data of the air conditioner itself;

For example, the internal fan of the air conditioner is driven by the electric energy supplied by the air conditioner. The actual speed of the internal fan is mainly affected by its current operating voltage and/or operating current, that is, the parameter of the internal fan speed is related to the operating voltage and/or The working current has a certain relationship. Therefore, by obtaining the operating data such as the current working voltage and/or working current of the internal fan, the current speed of the internal fan can be obtained by further combining the above-mentioned relationship;

The indoor unit of the air conditioner is equipped with a temperature sensor, and the temperature sensor can be used to detect the current temperature parameter of the indoor environment. In step S501, the current temperature parameter detected by the temperature sensor can be obtained and used as the first indoor temperature;

Similarly, the indoor unit of the air conditioner is equipped with a humidity sensor. The humidity sensor can be used to detect the current humidity parameter of the indoor environment. In step S501, the current humidity parameter detected by the humidity sensor can be obtained and used as the first indoor humidity;

Similarly, the indoor unit of the air conditioner is also equipped with another temperature sensor at the inner coil, which can be used to detect the current temperature parameter of the inner coil, and the current temperature parameter detected by the temperature sensor can be obtained in step S501 , and as the first inner coil temperature;

S502. Based on the first operating parameter, determine whether the air conditioner meets the first anti-condensation condition;

In this embodiment, the first anti-condensation condition is used to determine whether there is or will be condensation under the current operating conditions of the air conditioner; Condensation; and when the air conditioner does not meet the first anti-condensation condition, it is determined that the air conditioner does not exist or does not produce condensation. In this way, based on the first operating parameters and the judgment of the first anti-condensation condition, further determination can be made Subsequent operation of the air conditioner;

In this embodiment, the first anti-condensation condition includes at least the first rotational speed condition, the first humidity condition, the first inner coil temperature condition and the first duration condition, that is, whether the air conditioner in the present invention already exists or will produce condensation The condition judgment of the condensation problem is a comprehensive judgment based on the internal fan speed, temperature, humidity and operating time, etc., which can improve the accuracy of the judgment of the condensation problem of the air conditioner and avoid misjudgment problems caused by abnormal individual parameters;

Specifically, under the first speed condition, the speed of the internal fan is at a low wind speed gear; here, for existing types of air-conditioning products, the speed of the internal fan of the air conditioner is generally divided into multiple different gears, for example, a gear The division method is low wind speed gear, medium wind speed gear and high wind speed gear. Each gear corresponds to a speed value or speed range value. As the gear increases, the specific speed value or speed range value The value also increases accordingly; the first speed condition of the present invention is based on judging whether the current internal fan speed gear is in the low wind speed gear, if yes, then the first speed condition is satisfied; if not, then no meeting the first rotational speed condition;

Here, the advantage of introducing the parameter of the speed of the indoor fan into the judgment of the condensation problem of the air conditioner is that when the air conditioner is running at a lower speed, the speed of the indoor air flowing through the indoor unit is relatively low, and the time it stays inside the indoor unit is relatively low. Longer, so that the moisture in the indoor air can have sufficient time to condense into dew on the indoor heat exchanger. Therefore, when the speed of the internal fan is low, condensation may occur in the air conditioner.

The first humidity condition, the first indoor humidity is greater than the first humidity threshold; the first humidity threshold is used to characterize the indoor humidity, and the first indoor humidity generally takes a relatively large value, such as relative humidity 80%, relative humidity 90% %, etc.; here, when the indoor humidity is greater than the first humidity threshold, it means that the indoor humidity in the current indoor environment is relatively high, and the water vapor content is relatively high; when the indoor humidity is not greater than the first humidity threshold, it means that the current indoor environment The indoor humidity in the environment is low, and the water vapor content is low.

Here, the greater the indoor humidity, the more moisture will be mixed in the indoor air. When the indoor air flows through the indoor unit of the air conditioner, the more water vapor will easily condense into dew; It may cause condensation problems in the air conditioner.

The temperature condition of the first inner coil, the temperature of the first inner coil satisfies the following relationship:

The first inner coil temperature>the first indoor temperature-(D*first indoor temperature+E), where D is the calculation coefficient and E is the calculation constant;

The lower the temperature of the inner coil, the more dew will condense when the water vapor flows through the indoor unit. The above "first indoor temperature - (D* first indoor temperature + E)" is used to indicate that the inner coil is easy to condense dew When the current internal coil temperature is lower than this temperature limit, the low temperature environment of the internal coil will easily condense the water vapor in the indoor air flowing through it into dew; if the current internal coil temperature is not lower than this temperature limit When the temperature limit is lower, the amount of dew condensation caused by the low temperature environment of the inner coil is less;

Optionally, the value of the calculation coefficient D is 0.95, and the calculation coefficient of the calculation constant E is 0.26.

The first duration condition, the cumulative duration of the air conditioner meeting the first speed condition, the first humidity condition and the first inner coil temperature condition is greater than the first duration;

In this embodiment, if the accumulative time for the air conditioner to meet the first rotational speed condition, the first humidity condition, and the first inner coil temperature condition is relatively short, such as only for 1 minute, 2 minutes, etc., the actual condensation amount of the air conditioner is relatively short. less, it can be ignored. In the case of a long duration, the air conditioner is prone to condensation problems. Therefore, the first anti-condensation condition of the present invention also includes a first duration condition to reduce misjudgments caused by temperature and humidity fluctuations in a short period of time. And other issues.

Optionally, the value of the first duration is 1 hour;

S503. In response to the air conditioner meeting the first anti-condensation condition, control the air conditioner to perform a preset first anti-condensation operation.

The anti-condensation air conditioner control method provided by the present invention can accurately judge whether the current operating state and environmental conditions of the air conditioner may have caused the air conditioner to generate condensation by collecting various first operating parameters and making judgments in combination with preset anti-condensation conditions. Condensation problems, and timely implementation of preset anti-condensation operations to reduce the occurrence of air-conditioning condensation problems and improve user experience.

Optionally, for fixed-frequency air-conditioning products, since the operating frequency of the compressor cannot be adjusted, the first anti-condensation operation performed by the air-conditioner in step S503 includes: controlling to increase the speed of the internal fan of the air-conditioner to the first - set speed.

Here, the first set rotational speed is a rotational speed higher than the low wind speed gear, such as the middle wind speed gear or the high wind speed gear.

Alternatively, based on the low wind speed gear, the speed of the internal fan is increased by a set speed value, such as increasing by 30rpm, the adjusted speed of the internal fan is R+30, where R refers to the low wind speed gear.
