The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
First embodiment
Referring to fig. 1, an embodiment of the invention provides a method for controlling condensation prevention of an air conditioner. The air conditioner condensation prevention control method is applied to the air conditioner 1. It should be noted that the air conditioner 1 includes a module heat sink, which is a refrigerant heat sink and is disposed adjacent to the main control circuit system of the air conditioner 1. Optionally, the air conditioner condensation prevention control method may include the following steps:
step S101, collecting an ambient temperature corresponding to the air conditioner 1 and a temperature of the module radiator according to a preset time period.
In an embodiment of the present invention, the air conditioner 1 further includes a collection unit, which may include a plurality of temperature sensors. Optionally, a temperature sensor is included, disposed outside the air conditioner 1, for collecting the ambient temperature. The temperature sensor can be arranged on the outer side of the main control circuit system and used for acquiring the temperature of the radiator of the module 2. Optionally, in other embodiments, the temperature of the Module heat sink may be collected by an (Intelligent Power Module, IPM) Intelligent Power Module. The collected ambient temperature and the temperature of the module radiator are fed back to the controller of the air conditioner 1 for processing during each collected time period.
Step S102, acquiring a preset temperature threshold corresponding to the environment temperature according to a preset temperature interval to which the environment temperature belongs.
In the embodiment of the present invention, a plurality of temperature intervals are preset in the air conditioner 1, that is, the preset temperature interval may include a first interval, a second interval, and a third interval. Optionally, the first interval is a temperature interval smaller than a first temperature value, the second interval is a temperature interval not smaller than the first temperature value and smaller than a second temperature value, and the third interval is a temperature interval not smaller than the second temperature value. Preferably, the temperature value 0 ℃ belongs to the second interval, which may be, for example, -5 ℃ to 5 ℃. The second zone is set to an ambient temperature zone in which condensation is most likely to occur, and the ambient temperature zone is usually around 0 ℃.
Furthermore, each preset temperature interval corresponds to a preset temperature threshold. Specifically, the preset temperature threshold includes a first temperature threshold, a second temperature threshold and a third temperature threshold. The preset temperature threshold corresponding to the first interval is a first temperature threshold; the preset temperature threshold corresponding to the second interval is a second temperature threshold; the preset temperature threshold corresponding to the third interval is a third temperature threshold. Preferably, the first temperature threshold and the third temperature threshold are both greater than the second temperature threshold.
In this embodiment of the present invention, step S102 may be implemented by the following processes: and judging the preset temperature interval to which the acquired environment temperature belongs. If the environment temperature belongs to the first interval, taking the first temperature threshold as the acquired preset temperature threshold; if the environment temperature belongs to the second interval, taking the second temperature threshold as the acquired preset temperature threshold; and if the environment temperature belongs to the third interval, taking the third temperature threshold as the acquired preset temperature threshold.
Step S103, judging whether the module 4 radiator has the condensation phenomenon or not according to the environment temperature, the temperature of the module radiator and the corresponding preset temperature threshold value.
In the embodiment of the invention, whether condensation occurs at the ambient temperature and the temperature of the module radiator can be judged through the corresponding preset temperature threshold. Optionally, the temperature of the module radiator may be compared with the sum of the ambient temperature and the corresponding preset temperature threshold, and whether the condensation phenomenon occurs may be determined by combining the operation parameters of the air conditioner 1.
Specifically, the step S103 may be implemented as follows: the compressor operation time period of the air conditioner 1 is acquired. Specifically, the time length of the compressor start operation of the air conditioner 1 is recorded after the air conditioner 1 is started, and is taken as the compressor operation time length. And when the ambient temperature belongs to a first interval, the running time of the compressor reaches a first time and the temperature of the module radiator continuously collected in a second time is less than the sum of the ambient temperature and the first temperature threshold, judging that the condensation phenomenon occurs. And when the ambient temperature belongs to the second interval, the running time of the compressor reaches a third time and the temperature of the module radiator continuously collected in a fourth time is less than the sum of the ambient temperature and the second temperature threshold, judging that a condensation phenomenon occurs. And when the ambient temperature belongs to the third interval, the compressor operation time reaches a fifth time and the temperature of the module radiator continuously collected in a sixth time is less than the sum of the ambient temperature and the third temperature threshold, judging that a condensation phenomenon occurs.
It should be noted that, when the environmental temperatures belong to different preset temperature intervals, the difficulty level of generating condensation is different, and therefore, the determination parameters for determining whether the condensation phenomenon occurs are different. It should be noted that the above determination parameters include the compressor running time length, the preset temperature threshold, and the duration of time for acquiring the ambient temperature and the temperature of the module radiator that meet the requirements (e.g., the second time length mentioned in sub-step S1032, the fourth time length mentioned in sub-step S1033, and the sixth time length mentioned in sub-step S1034), and the like.
And step S104, if the condensation phenomenon is judged to occur, executing an anti-condensation strategy.
In an embodiment of the present invention, the above anti-condensation strategy includes enabling a shutdown protection mode of the air conditioner 1.
Further, the preset temperature threshold further includes a fourth temperature threshold, where the fourth temperature threshold is greater than the second temperature threshold, and when the ambient temperature belongs to the second interval and the temperature of the module radiator is less than the sum of the ambient temperature and the fourth temperature threshold, as shown in fig. 2, the air conditioner anti-condensation control method may further include the following steps:
step S201, acquiring a current operation mode of the air conditioner 1.
In the embodiment of the present invention, the operation modes of the air conditioner 1 are a heating mode and a non-heating mode. And when the ambient temperature belongs to the second interval and the temperature of the module radiator is less than the sum of the ambient temperature and a fourth temperature threshold, acquiring the current operation mode of the air conditioner 1.
Step S202, if the operation mode of the air conditioner 1 is a heating mode, the collected temperature of the module radiator is not less than the sum of the ambient temperature and the second temperature threshold value, and the operation wind level of the outer fan of the air conditioner 1 does not reach the highest wind level of the outer fan, the operation wind level of the outer fan is raised until the collected temperature of the module radiator is not less than the sum of the ambient temperature and the fourth temperature threshold value or the operation wind level of the outer fan reaches the highest wind level.
In the embodiment of the present invention, in the heating mode of the air conditioner 1, if the collected temperature of the module radiator is not less than the sum of the ambient temperature and the second temperature threshold, but is less than the sum of the ambient temperature and the fourth temperature threshold, the current operating wind level of the external fan is obtained. If the current operating wind level of the outer fan does not reach the highest wind level of the outer fan, the outer fan can be lifted by one level on the basis of the current operating wind level of the outer fan, and the outer fan can operate. And if the temperature of the module radiator collected again is still not less than the sum of the ambient temperature and the second temperature threshold but less than the sum of the ambient temperature and the fourth temperature threshold, repeatedly lifting the operating wind level of the first-level outer fan until the collected temperature of the module radiator is not less than the sum of the ambient temperature and the fourth temperature threshold or the operating wind level of the outer fan is lifted to reach the highest wind level of the outer fan.
Step S203, if the operation mode of the air conditioner 1 is a heating mode, the collected temperature of the module radiator is not less than the sum of the ambient temperature and the second temperature threshold, and the operation wind level of the outer fan of the air conditioner 1 reaches the highest wind level, the operation wind level of the inner fan of the air conditioner 1 is adjusted downward until the temperature of the module radiator is not less than the sum of the ambient temperature and the fourth temperature threshold or the operation wind level of the inner fan reaches the lowest wind level of the inner fan.
In the embodiment of the present invention, if the operating wind level of the outer fan has reached the maximum wind level of the outer fan, but the acquired temperature of the module radiator is still not less than the sum of the ambient temperature and the second temperature threshold, but is less than the sum of the ambient temperature and the fourth temperature threshold, the inner fan is controlled to lower the operating wind level by one level on the basis of the current operating wind level until the temperature of the module radiator is not less than the sum of the ambient temperature and the fourth temperature threshold or the operating wind level of the inner fan reaches the lowest wind level of the inner fan.
It should be noted that, when the temperature of the module radiator is not less than the sum of the ambient temperature and the second temperature threshold but less than the sum of the ambient temperature and the fourth temperature threshold, the condensation phenomenon does not occur in the air conditioner 1, but the edge where condensation occurs is already close to the temperature of the module radiator. Therefore, by adjusting the system operation load of the air conditioner 1, the occurrence of condensation is avoided. In the embodiment of the present invention, the adjustment of the system operation load of the air conditioner 1 may be performed by raising the wind level of the outer fan, or by lowering the wind level of the inner fan. Preferably, promote the windshield of outer fan earlier, reduce the windshield of interior fan again to ensure that the user is good to use and experiences.
Step S204, if the operation mode of the air conditioner 1 is not the heating mode and the collected temperature of the module radiator is less than the sum of the ambient temperature and the second temperature threshold for the fourth duration, starting the shutdown protection mode of the air conditioner 1.
Further, in order to timely find out a condensation alarm caused by a fault of the air conditioner 1, as shown in fig. 3, the air conditioner condensation prevention control method provided by the present invention may further include the following steps:
step S301, recording the number of times of the shutdown protection mode that the air conditioner 1 is activated.
In the embodiment of the present invention, the number of times of enabling the shutdown protection mode includes both the shutdown protection mode triggered by executing the anti-condensation policy and the shutdown protection mode triggered by executing step S204.
And step S302, when the number of times of the started shutdown protection mode within the seventh time length exceeds a preset number value, carrying out maintenance early warning. To remind professional maintenance personnel to overhaul.
Further, when the air conditioner 1 is just started to operate, that is, when the air conditioner 1 receives an operation instruction triggered by a user, the air conditioner condensation prevention control method further includes: the ambient temperature of the air conditioner 1 and the temperature of the module radiator are collected. And if the temperature of the module radiator is less than the ambient temperature and a preset fifth temperature threshold value and the duration time reaches eighth duration, forbidding starting and carrying out maintenance early warning. The damage to the air conditioner 1 caused by forced start-up of the air conditioner 1 when the air conditioner 1 has a condensation phenomenon due to self faults is avoided.
