fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A control method of an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings
First, an air conditioner according to an embodiment of the present invention is described by way of example.
The air conditioner according to the embodiment of the invention can be a mobile air conditioner, the mobile air conditioner comprises an outdoor heat exchanger, a compressor, an indoor heat exchanger, a throttling assembly and other components, the outdoor heat exchanger, the compressor, the indoor heat exchanger and the throttling assembly are connected into a refrigerant loop and are arranged in the same box body, wherein the compressor and the outdoor heat exchanger can be positioned at the lower part, and the indoor heat exchanger can be positioned at the upper part.
The air conditioner is provided with an outdoor air duct and an outdoor fan which correspond to the outdoor heat exchanger, and the air guide quantity of the outdoor heat exchanger is controlled through the outdoor fan, so that air is blown to the outdoor heat exchanger in a circulating mode.
The air conditioner is also provided with an indoor air duct and an indoor fan which correspond to the indoor side heat exchanger, and the air guide quantity of the indoor side heat exchanger is controlled through the indoor fan, so that air is supplied to adjust the temperature of a closed or local space, and the refrigerating and heating requirements of a user are met.
Among them, the air conditioner is provided with a drainage device, such as a water pump, for discharging condensed water.
As shown in fig. 1, a control method of an air conditioner according to an embodiment of the present invention includes:
detecting a condensed water level, and judging whether the condensed water level H1 reaches a rated maximum water level H2 for a first preset time T1;
if yes, detecting an environment temperature W1, and judging whether the environment temperature W1 is smaller than a preset temperature W2;
if not, controlling to discharge the condensed water, for example, turning on a water pump to realize water drainage;
if so, adjusting the air guide amount of the outdoor heat exchanger to be the lowest (for example, adjusting the rotating speed of the outdoor fan to be the lowest) for a second preset time T2, detecting a condensed water level H1, and judging whether the condensed water level H1 reaches a rated highest water level H2 and continues for a third preset time T3;
if yes, the condensed water is controlled to be discharged, for example, the water pump is turned on to discharge the condensed water.
According to the control method of the air conditioner, when the condensate water level H1 reaches the rated maximum water level H2 and lasts for the first preset time T1, the fact that the current production speed of condensate water is larger than the evaporation speed of the condensate water and a certain volume of condensate water is stored indicates that the risk of overflow of the condensate water exists when the air conditioner continues to operate, the ambient temperature W1 of the air conditioner is detected, and when the ambient temperature W1 is larger than or equal to the preset temperature W2, the water pump is started to start water drainage; when the ambient temperature W1 is less than the preset temperature W2, the air guiding amount of the outdoor side heat exchanger is adjusted to be the lowest and lasts for a second preset time T2.
It can be understood that when the ambient temperature W1 is greater than or equal to the preset temperature W2, the cooling capacity of the air conditioner is more important, and thus the air conditioner is maintained in an optimal cooling state by direct drainage; when the ambient temperature W1 is lower than the preset temperature W2, the refrigeration demand of the user on the air conditioner is not very high, that is, the refrigeration capacity of the air conditioner may not be in an optimal state, so that the air deflection of the outdoor side heat exchanger is reduced, the shaking of the air conditioner is reduced, the shaking amplitude of the condensed water is further reduced, the detected condensed water level H1 is ensured to be more accurate, the condition that the condensed water level H1 is misdetected is prevented, the air deflection of the outdoor side heat exchanger is reduced, the heat value of heat exchange between the outdoor air deflection and the outdoor side heat exchanger is reduced, so that more heat of the outdoor side heat exchanger is transferred to the condensed water, the evaporation of the condensed water is accelerated, after the lowest outdoor air deflection second preset time T2 is maintained, the current condensed water level H1 is detected, and if the condensed water level H1 does not reach the rated highest water level H2, it is indicated that the evaporation speed of the condensed water is higher than the generation speed of the condensed water within the second preset time T2, the level of the condensed water is lowered, so that the normal operation of the air conditioner can be ensured.
In addition, if the condensed water level H1 reaches the rated maximum water level H2, it is detected whether the condensed water level H1 is at the rated maximum water level H2 for a third preset time T3, and if so, the air conditioner turns on the water pump. If not, the condensed water level H1 reaches the rated highest water level H2, but the condensed water level H1 is lower than the rated highest water level H2 within the third preset time T3, at this time, the air guide quantity of the outdoor heat exchanger of the third preset time T3 is always the lowest, the evaporation speed of the condensed water is higher than the generation speed of the condensed water, but the difference between the evaporation speed and the condensation speed is smaller, so the condensed water level is reduced slowly, and at this time, the water pump does not need to be started.
Therefore, the control method of the air conditioner can realize automatic discharge of the condensed water, reduce the frequency of discharging the condensed water and give consideration to environmental comfort.
According to some embodiments of the invention, the first predetermined time T1 is 2s to 5s, for example 3s, and the third predetermined time T3 is 2s to 5s, for example 3 s. Therefore, when the condensed water level H1 reaches the rated highest water level H2, the condensed water level H1 can be indicated more accurately by continuously detecting for 2 s-5 s, and the situation that the water pump is directly started because the condensed water level H1 shakes to cause the condensed water level H1 to reach the rated highest water level H2 is prevented. And the continuous first preset time T1 and the third preset time T3 are 2 s-5 s, so that a large amount of condensed water cannot be generated in 2 s-5 s, the condensed water can be prevented from overflowing the air conditioner, and the safety of the air conditioner is ensured, so that the setting of 2 s-5 s is realized, and the accuracy of the detection of the water level of the condensed water and the use safety of the air conditioner are both considered.
According to some embodiments of the invention, the predetermined temperature W2 is 31 ℃ to 33 ℃, for example 32 ℃. Since most users have high requirements for the refrigerating capacity of the air conditioner at the temperature of 31-33 ℃, the air conditioner uses the temperature of 31-33 ℃ as a preset temperature as a reference factor for judging whether the air conditioner reduces the air guiding quantity of the outdoor heat exchanger.
According to some embodiments of the invention, the second predetermined time T2 is 30s to 60 s. Therefore, the outdoor heat exchanger can fully evaporate the condensed water, the evaporating speed of the condensed water and the speed of the condensed water generation speed can be more accurately shown by lasting 30-60 s, and if the evaporating speed of the condensed water is less than the condensed water generation speed, the storage amount of the condensed water is small because the evaporating speed of the outdoor heat exchanger is the maximum and the time length is 30-60 s, the probability of overflowing the condensed water is reduced, and the safety of the air conditioner is ensured. Thus, the second preset time is set to be 30-60 s, and the evaporation effect of the outdoor heat exchanger and the use safety of the air conditioner can be considered at the same time.
According to some embodiments of the present invention, after controlling the draining of the condensed water, the method further comprises:
judging whether the condensed water level H1 is lower than the rated highest water level H2 for a fourth preset time T4;
if so, adjusting the air guide amount of the outdoor heat exchanger to be the highest (for example, adjusting the rotating speed of the outdoor fan to be the highest) and continuing for a fifth preset time T5;
detecting a condensed water level H1, and judging whether the condensed water level H1 is lower than the rated highest water level H2 for a sixth preset time T6;
if yes, controlling to stop discharging the condensed water.
This continues for a fourth predetermined time T4, at which the condensate level H1 is still below the nominal maximum level H2, indicating that condensate from the condensate reservoir has been significantly drained. The air guide amount of the outdoor heat exchanger is adjusted to be the highest and lasts for a fifth preset time T5, so that air circulation inside the air conditioner is accelerated, most of condensed water outside each part inside the air conditioner or on the inner wall of the air conditioner flows into the condensed water collecting device, the current situation of the condensed water level H1 is detected and judged again, the condensed water can be conveniently discharged by a large margin when the drainage device is started every time, and the drainage device is prevented from being started repeatedly.
According to some embodiments of the invention, the fourth predetermined time T4 is 2s to 5s, for example 3s, and the sixth predetermined time T6 is 2s to 5s, for example 3 s. Therefore, when the condensed water level H1 reaches the rated highest water level H2, the condensed water level H1 can be indicated more accurately by continuously detecting for 2 s-5 s, and the situation that the water pump is directly started because the condensed water level H1 shakes to cause the condensed water level H1 to reach the rated highest water level H2 is prevented. And the continuous first preset time T1 and the third preset time T3 are 2 s-5 s, so that a large amount of condensed water cannot be generated in 2 s-5 s, the condensed water can be prevented from overflowing the air conditioner, and the safety of the air conditioner is ensured, so that the setting of 2 s-5 s is realized, and the accuracy of the detection of the water level of the condensed water and the use safety of the air conditioner are both considered.
According to some embodiments of the present invention, the fifth predetermined time T5 is 30s to 60s, which ensures that air inside the air conditioner is fully circulated, that is, most of the condensed water outside the components inside the air conditioner or inside the wall of the air conditioner flows into the condensed water collecting device, so that the drainage device is turned on once to fully drain the condensed water of the air conditioner, and the condensed water level H1 is prevented from reaching the rated maximum water level H2 after a short time interval.
According to some embodiments of the present invention, the discharging of the condensed water is controlled to determine whether a duration of the discharging of the condensed water reaches a seventh preset time T7;
if so, control stops draining the condensed water, for example by turning off the water pump.
In other words, when the water pump is continuously turned on for the seventh preset time T7 and the condensed water level H1 is still at the rated maximum level H2, it indicates that the drain device (e.g., the water pump) or the water level detection device (e.g., the water level switch) has failed, and thus the control stops discharging the condensed water, i.e., turns off the water pump, which prevents the water pump from being damaged due to the continuous operation of the water pump.
According to some embodiments of the invention, the seventh preset time T7 is 100 s. This not only allows sufficient time for draining the condensed water, but also prevents the drain (e.g., water pump) from being damaged due to long-term operation.
According to some embodiments of the invention, if the duration of the condensed water drainage is determined to reach the seventh preset time T7, a fault is sent out.
In other words, if the water pump is continuously turned on for the seventh preset time T7(100S) and the condensed water level H1 is still at the rated maximum water level H2, it indicates that the drainage device (e.g., water pump) or the water level detection device (e.g., water level switch) has failed, so that a failure prompt is issued, which can prompt the user to check the water pump of the air conditioner and the device for detecting the condensed water level, and also prompt the user to turn off the air conditioner to prevent the condensed water from overflowing.
Other configurations and operations of the air conditioner according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
For example, the air conditioner in the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The indoor side heat exchanger and the outdoor side heat exchanger function as a condenser or an evaporator. When the indoor side heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor side heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
