Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
When the air conditioner dehumidifies and refrigerates, because of the lower evaporation temperature of the inner disc of the indoor unit, condensed water condenses and drops in the water receiving tank, and the condensed water needs to be discharged out of the water receiving tank through the water pump. The air conditioner has different water pump start-stop control modes, and when the air conditioner is in a water pump normally open mode, the water pump can be always in an open state, so that drainage operation of condensed water is performed in real time. If the air conditioner is always in the control mode of normally opening the water pump, the normally opening of the water pump is probably no longer suitable for the current environment due to the change of the environment temperature and humidity of the air conditioner, and unnecessary resource waste is caused.
In order to solve the above problems, the present invention provides a method for controlling a water pump of an air conditioner.

after the air conditioner is started, whether the air conditioner operates in a refrigeration mode or a dehumidification mode is detected, if so, the air conditioner water pump enters a normally open mode, and the air conditioner water pump is controlled to be normally open. If the air conditioner is detected not to run in the refrigeration mode and not to run in the dehumidification mode, the normally open water pump is not used according to the embodiment of the invention, and the closing state of the water pump can be kept unchanged.
Along with time lapse, the air conditioner that is in refrigeration mode or dehumidification mode adjusts ambient environment, reduces ambient humidity and ambient temperature, so, air conditioner comdenstion water condensation rate slows down, and its condensation water yield also is more slow than the rate of need discharging, and at this moment, the water pump can not keep normally open state, and changeable to intelligent control mode carries out the intelligent control water pump and opens and stop the operation.
The method comprises the steps that the determination of the opportunity when the air conditioner water pump is switched from the normally open mode to the intelligent control mode is carried out through obtaining relevant parameters for judgment, and the relevant parameters are relevant to the mode of specifically judging the opportunity for switching the mode.
Mode switching opportunity (namely opportunity for switching the air conditioner water pump from the normally open mode to the intelligent control mode) can be judged in various ways, optionally, the preset mode switching condition is as follows:
the air conditioner water pump control method includes at least one of a first condition, a second condition and a third condition, wherein the first condition is that the amount of water discharged from the air conditioner water pump is greater than or equal to a preset amount of water, the second condition is that the current actual ambient temperature and ambient humidity respectively reach a target temperature and a target humidity, and the third condition is that the normally open time of the air conditioner water pump is greater than or equal to a first preset time.
The air conditioner can detect relevant parameters in real time or at regular time, and judge whether the preset mode switching condition is met.
For the first condition: after the air conditioner is started and runs in a refrigeration mode or a dehumidification mode, the water quantity in the air to be removed from the initial working condition to the target working condition can be obtained through table lookup and calculation, and the water quantity is used as the preset water quantity in each embodiment of the invention. Detecting the actual water discharge quantity of the water pump of the air conditioner in real time or at regular time, comparing the actual water discharge quantity with the preset water quantity, judging whether the current mode switching time is proper or not by comparing the actual water discharge quantity of the water pump of the air conditioner with the preset water quantity, and when the actual water discharge quantity of the water pump of the air conditioner is more than or equal to the preset water quantity, removing much water in the ambient air of the air conditioner, greatly reducing the humidity, and switching the modes; when the actual water discharge amount of the water pump of the air conditioner is smaller than the preset water amount, the humidity of the ambient air where the air conditioner is located may not be small, and the water pump can be continuously kept normally open. The flow meter can be arranged at the outlet of the air conditioner water pump to detect the actual water discharge quantity of the air conditioner water pump.
For the second condition: the environmental working condition is detected in real time or at regular time, the actual environmental working condition is compared with the target working condition, the target working condition can be set by a user, can be preset by a manufacturer, and can be determined together according to the user setting and the manufacturer presetting. When the environmental condition reaches the target condition, it usually means that the actual environmental temperature is equal to the target environmental temperature and the environmental humidity is equal to the target humidity, or the absolute value of the difference between the actual environmental temperature and the target environmental temperature, the actual environmental humidity and the target humidity is small. The current actual environment working condition reaches the target working condition, and shows that under the current environment, the air temperature and humidity is lower, and the condensate water condensation speed is lower, and at the moment, mode switching can be carried out. Optionally, when the second condition determination is made, the following steps are performed: acquiring the current actual environment temperature and environment humidity, and the set target environment temperature and environment humidity; judging whether the current actual environmental temperature and the current actual environmental humidity reach the target environmental temperature and the target environmental humidity; and if so, judging that the air conditioner water pump meets a preset mode switching condition.
For the third condition: the normally open time of the water pump of the air conditioner refers to the time when the water pump is normally open after the air conditioner is started to operate in a refrigeration mode or a dehumidification mode, the longer the water pump is started, the more moisture is removed from the air, and after the water pump is started for a certain time, the mode switching can be carried out. The first preset time in each embodiment of the invention can be determined according to an initial working condition, wherein the initial working condition refers to the ambient temperature and the ambient humidity when the air conditioner starts to operate in a refrigeration mode or a dehumidification mode, the higher the ambient temperature and the ambient humidity are, the longer the first preset time is, the calculation mode among the ambient temperature, the ambient humidity and the first preset time can be preset in the air conditioner, and after the air conditioner is started, the ambient temperature and the ambient humidity are detected to calculate the first preset time.
Optionally, when the air conditioner water pump meets the first condition, it is determined that the air conditioner water pump meets the preset mode switching condition. Optionally, when the air conditioner water pump meets the second condition, it is determined that the air conditioner water pump meets the preset mode switching condition. Optionally, when the air conditioner water pump meets the third condition, it is determined that the air conditioner water pump meets the preset mode switching condition. Optionally, when the air conditioner water pump meets any one of the first condition, the second condition and the third condition, the air conditioner water pump is determined to meet the preset mode switching condition.
Through setting up suitable mode switching condition of predetermineeing for the air conditioner carries out the switching of water pump control mode at suitable opportunity, and then when guaranteeing the timely drainage of air conditioner water pump, practices thrift the energy consumption.
If the air conditioner water pump does not meet all the conditions, the air conditioner water pump is judged to not meet the preset mode switching conditions, the air conditioner water pump is continuously controlled in a normally open mode, relevant parameters can be obtained immediately or after a certain time, and the mode switching time is judged.
And step S30, if the air conditioner water pump meets the preset mode switching condition, controlling the air conditioner water pump to be switched from a normally open mode to an intelligent control mode.
After the air conditioner water pump is switched to the intelligent control mode from the normally open mode, the air conditioner water pump is not normally open any more, but the intelligent control water pump is started and stopped.
Through setting up the normal open mode and the intelligent control mode of controlling air conditioner water pump work, can avoid the water pump frequently to open and stop and lead to the fact harmful effects to its life under the circumstances that guarantees that the air conditioner comdenstion water can in time be discharged, still can energy saving, noise abatement promotes the user and uses the travelling comfort. Particularly, when the air conditioner operates in a refrigeration or dehumidification mode, the temperature and the humidity of the environment where the air conditioner is located are high, the condensation speed of condensed water is high, the water pump of the air conditioner is controlled in a normally open mode, the water pump is kept normally open, the condensed water can be timely and thoroughly discharged, the frequent starting and stopping of the water pump are avoided, and other complex control steps are not needed in the normally open mode, so that the energy consumption can be saved; when the temperature and humidity of the environment are low and the condensation speed of the condensed water is low, if the water pump is normally open, the accumulation speed of the condensed water amount is possibly far lower than the discharge speed of the water pump, so that unnecessary energy consumption is caused, and by setting an intelligent control mode of the water pump of the air conditioner, the water pump can be controlled to be closed when the accumulated condensed water amount does not reach the discharge amount, so that the energy consumption is saved; in addition, because the water pump operation can produce the noise, through mode switch, can make the water pump be in the off-state at some time to reduce the noise. Therefore, by setting the normally open mode and the intelligent control mode and determining the appropriate mode switching opportunity, the effects of timely discharging the condensed water, avoiding frequent starting and stopping of the water pump, saving energy consumption and the like can be realized.
