The controller continues to check whether there is a new water demand, i.e. it is equivalent to confirm whether the current water demand is met, and if there is no water demand, then a new round of water level check is entered.
If the water level of the first water tank is lower than that of the first water level detection piece, the controller supplies power to the power jack, and meanwhile, the controller detects whether the power supply of the water pump is normally connected. For example, after the controller supplies power to the water pump, the controller detects whether a direct current power supply loop connected with the water pump has current, so as to determine whether a power supply plug of the water pump is correctly connected and plugged into a power supply jack arranged at the bottom or the side part of the air conditioner, or detect whether feedback information exists in the water pump, or connect a resistor in series on the power supply loop connected with the water pump, and measure voltage values at two ends of the resistor to judge whether the power supply of the water pump is correctly connected with the air conditioner body, and the like. If no current signal exists in the power supply loop of the water pump, or no feedback signal of the water pump exists, or no voltage value exists at two ends of a resistor connected in series with the power supply loop of the water pump, or the voltage value is too low, the water pump power supply is judged to be abnormally connected, a controller gives prompt information to prompt a user to connect the water pump power supply, and a power plug of the water pump is inserted into the power jack.
If the controller detects that the power supply of the water pump is normally connected, the water pump is started to add water into the first water tank, meanwhile, the timer T starts to time from 0, after the water pump adds water into the first water tank, when the water level reaches the water level of the second water level detection piece, namely, when the water level is higher than or equal to the water level of the second water level detection piece (upper water level), the water pump is stopped, and the controller continuously checks whether the air conditioning system has a water demand. After the water pump is started to add water into the first water tank, if the water level is lower than the water level of the second water level detection piece (upper water level), the water pump continues to operate to add water into the first water tank, the timer T accumulates the total operation time of the water pump from the start to the current time, then, whether the value of the timer T is larger than a first preset time value T1 is judged, a first preset time value T1 is set, the accumulated operation time value of the water pump is compared with the first preset time value T1, the water pump is prevented from having no water in the second water tank, or a user is not connected with an external water inlet pipe, the water pump does not stop or prompt information is provided for the user after long-time no-load operation, so that the first preset time value T1 is set as the maximum time value of one-time operation of the water pump, the size of the time value, and the time required when the water in the first water tank is filled from an empty water tank is comprehensively set according to the flow rate and the lift of the water pump and the volume of the first water tank, the first preset time value T1 may be set to be generally 1.21 to 1.2 times the length of time required for the current water pump to fill the first water tank from the empty water tank to the second water level detecting member.
When the first water tank is not provided with the water overflow outlet, the water level in the first water tank can reach the water level of the second water level detection piece after the accumulated running time of the water pump reaches the time value of T1, and the water level cannot overflow out of the first water tank. Of course, when the first water tank is provided with a drain hole or a structure for overflowing the water, the value of T1 may be set a little larger as appropriate. If the current timer T is still less than the first preset time T1, it is continuously checked whether the current water level of the first water tank is higher than or equal to the water level (upper water level) of the second water level detecting element, that is, it is determined whether the first water tank is filled with water. If the water level is lower than the water level of the water level detection piece, the water pump continues to add water, and the timer T continues to accumulate the water adding time length. If the value of the timer T is larger than the value of T1 and the water level of the first water tank is lower than the water level of the second water level detection piece, the user is prompted to connect the external water inlet pipe and to add water to the second water tank, for example, light is given to flash or an indicator light is turned on, or voice prompt is given. It is external inlet tube that specifically need to connect, still need add water for the second water tank, look over the back by the user and confirm. When the external water inlet pipe is connected by a user, or water is added into the second water tank, the user eliminates the water shortage prompt given by the controller at present through the reset key, and the timer T is reset. And detecting the water consumption of the air conditioning system entering the next circulation.

When the diaphragm water pump is started to add water into the first water tank, if the water level is lower than the water level of the second water level detection piece (upper water level), the diaphragm water pump continues to operate to add water into the first water tank, the timer T accumulates the total operation time of the diaphragm water pump from the start to the current, then, whether the value of the timer T is larger than a first preset time value T1 is judged, a first preset time value T1 is set, the time value of the accumulated operation of the diaphragm water pump is compared with the first preset time value T1, in order to prevent the second water tank from being empty or prevent a user from being connected with an external water inlet pipe, the diaphragm water pump does not stop or give a prompt message to the user all the time in no-load operation, therefore, the first preset time value T1 is set as the maximum time value of one-time operation of the water pump, the size of the time value is comprehensively set according to the flow rate and lift of the diaphragm water pump and the volume of the first water tank when the water of the first water tank is filled from the empty tank, the first preset time value T1 may be set to be generally 1.2 to 2 times the time length of the total time required for the current diaphragm water pump to fill the first tank from an empty tank. If the current timer T is still less than the first preset time T1, it is continuously checked whether the current water level of the first water tank is higher than or equal to the water level (upper water level) of the second water level detecting element, that is, it is determined whether the first water tank is filled with water. If the water level is lower than the water level of the water level detection piece, the diaphragm water pump continues to add water, and the timer T continues to accumulate the water adding time length. If the value of the timer T is larger than the value of T1 and the water level of the first water tank is lower than the water level of the second water level detection piece, the user is prompted to connect the external water inlet pipe and to add water to the second water tank, for example, light is given to flash or an indicator light is turned on, or voice prompt is given.
It is external inlet tube that specifically need to connect, still need add water for the second water tank, look over the back by the user and confirm. When the external water inlet pipe is connected by a user, or water is added into the second water tank, the user eliminates the water shortage prompt given by the controller at present through the reset key, and the timer T is reset.
