As shown in fig. 3, based on the air conditioner of fig. 1 or 2, an embodiment of the first aspect of the present invention provides a control method of an air conditioner, including, but not limited to, steps S110 to S130:
step S110: and under the condition that the water pumping motor and the water adding device are started, acquiring the operation parameters of the condenser.
After the air conditioner is started, a user selects the operation mode of the air conditioner to be a refrigeration mode or a dehumidification mode, the refrigeration system starts to start, the compressor of the air conditioner operates at a target frequency, the normal working state is guaranteed, when the water pumping motor and the water adding device are in the starting state, the water adding device keeps supplying water to the water receiving disc, the water pumping motor continuously consumes water in the water receiving disc, and therefore the cooling effect of the auxiliary condenser is achieved, and the refrigerating capacity of the air conditioner is improved. The operational parameters of the condenser may be temperature parameters, humidity parameters, wind speed parameters, wind direction parameters, run time parameters, or other suitable operational parameters.
Step S120: and acquiring the water consumption state of the air conditioner.
The step S120 of obtaining the water consumption state of the air conditioner includes:
and calculating to obtain the first water consumption of the condenser side according to the operation parameters.
The first water consumption is the actual water consumption of the condenser side, the water pumping effect of the water pumping motor can be reflected, the actual cooling effect of the condenser can be determined by acquiring the operation parameters of the condenser and calculating the first water consumption according to the operation parameters.
Step S130: and controlling the working state of the water adding device according to the water consumption state of the air conditioner.
The water consumption state of the air conditioner can control the working state of the water adding device, for example, the water supplementing speed of the water adding device can be adjusted, the water pumping motor is ensured to work under proper water quantity, the water pumping motor can achieve better water pumping effect, the good cooling effect of the condenser is ensured, and the refrigerating effect of the air conditioner is improved, so that the energy efficiency of the air conditioner is improved.
According to the control method of the air conditioner, the water consumption state of the air conditioner is obtained, the working state of the water adding device is controlled according to the water consumption state of the air conditioner, so that the water pumping machine can reach a better running state, the first water consumption of the condenser side is calculated according to the running parameters, the water consumption state of the air conditioner can be reflected, the working state of the water adding device is adjusted in time according to the water consumption state of the air conditioner, the water pumping effect of the water pumping motor is improved, the heat exchange efficiency of the condenser is improved, the air conditioner can always run in an optimal state, and the refrigerating capacity of the air conditioner is improved.
As shown in fig. 4, in the control method of the air conditioner, the method further includes, but is not limited to, step S210 and step S220:
step S210: acquiring the current water level of water in a water receiving disc;
step S220: and controlling the working state of the water adding device according to the current water level height.
Because the air conditioner consumes the speed of water under different running conditions and is different, the current water level of water in the water collector also can change, through detecting the current water level of water in the water collector to control the working condition of the water adding device, can guarantee that current water level is kept in suitable water level interval all the time, make the water pumping machine can keep the better effect of fetching water, be favorable to improving the heat exchange efficiency of condenser.
As shown in fig. 1 or 2, a water level switch 210 may be installed on the water pan 200, and the water level switch 210 is used to detect the current water level of water in the water pan 200.
In the above method for controlling an air conditioner, in step S220, controlling the working state of the water adding device according to the current water level height includes:
when the current water level is greater than or equal to the preset water level, the water adding device is controlled to be closed.
It should be noted that, the preset water level is the limited water level of the water pan, along with the continuous water supply of the water adding device to the water pan, the situation that water overflows is easy to occur, by comparing the current water level with the preset water level, if the current water level is greater than or equal to the preset water level, the water level in the water pan reaches the limited water level, the risk of water overflow is indicated, the water adding device is controlled to be closed, the water pumping motor keeps in a normal working state, the water in the water pan is continuously consumed, the current water level of the water in the water pan is reduced, the situation that water overflows is avoided, and the working stability of the air conditioner is ensured.
It can be understood that when the current water level of the water in the water receiving tray reaches the preset water level, the water adding device is controlled to be closed by keeping the opening state of the water pumping motor, namely, water is only consumed when the water level is limited, and the water full protection control logic without water supplement is adopted, so that the water consumption in the water receiving tray can be accelerated, and the current water level of the water in the water receiving tray is reduced to a proper water level interval.
As shown in fig. 1 or 2, in particular, the water adding device 300 may include the solenoid valve 210 or the water pump 220, and in case that the water adding device 300 includes the solenoid valve 210, the current water level of the water in the water receiving tray 200 can be reduced by closing the solenoid valve 210 and maintaining the opened state of the water pumping motor 400, and in the same way, when the water adding device 300 includes the water pump 220, the water pump 220 is controlled to be turned off and the water pumping motor 400 is maintained to be opened, the possibility of water overflow can be effectively avoided.
As shown in fig. 5, in the above-mentioned control method of the air conditioner, the operation parameters include a wind speed passing through the condenser, a first temperature and a first relative humidity on an air intake side of the condenser, a second temperature and a second relative humidity on an air outlet side of the condenser, and the first water consumption on the condenser side is calculated according to the operation parameters in step S120, including but not limited to steps S310 to S330:
Step S310: obtaining a first moisture content of an air inlet side of the condenser according to the first temperature and the first relative humidity;
step S320: obtaining a second moisture content of the air outlet side of the condenser according to the second temperature and the second relative humidity;
the relative humidity refers to the ratio of the partial pressure of water vapor in the humid air to the partial pressure of water vapor in the saturated humid air at the same temperature. The moisture content, also called specific humidity, refers to the mass of water vapor carried in 1kg of dry air.
It will be appreciated that the first temperature and the first relative humidity are the inlet air temperature and the inlet air relative humidity of the condenser, respectively, the first moisture content being indicative of the inlet air moisture content of the condenser, and the second temperature and the second relative humidity being indicative of the outlet air moisture content of the condenser, respectively.
