All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the outer side of the air conditioner begins to frost, the outer side heat exchange effect is poor, the condensing (actually evaporating) pressure of the outer side refrigerant is reduced, and the condensing (actually evaporating) temperature is lowered; according to the pressure-enthalpy diagram, the evaporation (actually condensation) pressure of the refrigerant at the inner side is reduced, and the evaporation (actually condensation) temperature is lowered, so that whether frosting is formed or not can be judged according to the temperature change of the inner disc of the indoor heat exchanger, and the defrosting cycle is started. Based on this, the present embodiment provides a method for controlling an air conditioner to enter a defrosting mode based on an inner disk temperature of the air conditioner. As described in detail below.
Example one
Fig. 1 schematically shows a flowchart of a control method provided by a first embodiment of the present invention, and as shown in fig. 1, the method may include operations S101 to S106, for example.
And S101, judging whether the air conditioner stably operates.
In a feasible manner of this embodiment, whether the air conditioner is operating stably can be determined according to the air outlet temperature and the air inlet temperature of the air conditioner, and the stable operation of the air conditioner may refer to that the air conditioner is operating at the same wind shield or the same set temperature, or operating for a set time, for example. Specifically, the temperature sensor is adopted to obtain the temperature of the air outlet and the temperature of the air inlet, the absolute value of the difference value between the temperature of the air inlet and the temperature of the air outlet is calculated, and if the absolute value is larger than or equal to a preset temperature difference threshold value, the running state of the air conditioner is judged to be normal. The present invention is not limited to the specific determination method. If yes, operation S102 is performed.
S102, after the air conditioner stably operates for a preset time period, collecting the inner disc temperature X of the air conditioner at the current moment, and collecting the inner disc temperature Y of the air conditioner at intervals of a preset period.
In a feasible mode of the embodiment, after the air conditioner stably operates for a period of time, the temperature T of the inner disc of the air conditioner is acquirednAnd recording the acquired initial value as X, and acquiring the temperature of the inner disc at intervals of a preset period in real time in the subsequent operation process as Y. The specific temperature acquisition mode can adopt airThe temperature sensor is installed, and the invention is not limited.
In a feasible manner of this embodiment, the preset period may be set to 1min to 2min, for example, 1min, and the preset time period for stable operation of the air conditioner may be, for example, 10min, and the specific value is not limited in the present invention.
S103, judging whether the value of Y/X is larger than or equal to a preset value.
In the embodiment, the change of the inner panel temperature is judged by calculating Y/X, and when Y/X is greater than a preset value a, it indicates that the inner panel temperature is rising or within a normal fluctuation range, and at this time, the air conditioner is not frosted, and operation S102 is continuously performed to collect inner panel temperature data. When Y/X is less than the preset value A, it indicates that the inner disc temperature is decreasing, and operation S104 is performed.
The preset value A is a settable parameter, and the larger the value is, the easier the frosting judgment condition is entered, and the defrosting frequency is high. In a feasible manner of this embodiment, the value of the preset value a ranges from 0.95 to 0.97, for example, the value of a is set to 0.96, and the specific value of a is not limited in the present invention.
And S104, calculating the difference value between the inner plate temperature of the air conditioner in the next period and the inner plate temperature of the air conditioner in the current period.
Obtaining an inner disc temperature difference Z according to the inner disc temperature of the air conditioner collected in operation S102i＝Tni+1-TniWherein, Tni+1Indicating the temperature of the inner panel of the air conditioner, T, in the next cycleniIndicating the air conditioner inner panel temperature of the current cycle.
And S105, judging whether the difference value is less than zero.
If the difference is less than zero, operation S106 is performed.
If the difference is greater than or equal to zero, the following two operations may be performed.
As shown in fig. 2, if the difference is greater than or equal to zero, the number of cycles with a difference smaller than zero is reset to zero, and the operation returns to operation S104, and the number of cycles with a difference smaller than zero is recalculated.
As shown in fig. 3, if the difference is greater than or equal to zero, the operation may return to operation S103 to re-execute the process for determination.
The two different operation modes can be more suitable for various sudden conditions in the air conditioner operation process, and the judgment precision is more accurate.
And S106, calculating the number of the periods with the difference value less than zero.
In operation S106, the inner tray temperature of the air conditioner collected in real time at preset intervals is calculated, the difference between the next collected inner tray temperature and the current inner tray temperature is repeatedly and continuously calculated, and if the difference is smaller than zero, the number of cycles with the difference smaller than zero is increased by 1.
And S107, controlling the air conditioner to enter a defrosting mode under the condition that the difference values of the continuous N periods are all less than zero.
If N consecutive periods ZiIf the temperature of the inner disc is less than 0, the temperature of the inner disc is continuously reduced, the temperature of the inner disc reaches a trigger condition at more than a certain moment, so that the frosting of the system can be judged, and the air conditioner is controlled to enter a defrosting mode. In a feasible manner of this embodiment, the value of N is not less than 5, for example, 10 consecutive cycles may be selected in the determination process, and the specific number of cycles is not limited in the present invention.
In addition, in the above control method, different dampers have a large influence on the change of the inner disc temperature, so that different dampers need to be distinguished in the determination process of the inner disc temperature. And in the running process of the air conditioner, if the wind level of the air conditioner is changed, the control method is executed again for judgment. That is, the control logic is under the same wind gear, and if the wind gear changes, the flow is restarted.
The above control method is further illustrated below by way of a specific example.
When the air conditioner is in operation, the air gear of the internal machine is high, when the air conditioner is in stable operation for 10min, the temperature of the inner disc is collected to be 50 ℃, and the temperature is marked as X; and acquiring a group of inner disc temperatures (such as 49.6 ℃) every 1min of a period, marking as Y, setting the value of A as 0.96, wherein Y/X is 0.99 to 0.96, and judging that the air conditioner is not frosted when the inner disc temperatures are in a normal fluctuation range.
And continuously collecting the temperature data of the inner disc, wherein when the temperature of the inner disc is 47.4 ℃, the Y/X is not less than 0.95 and not more than 0.96. At this time, the temperature of the inner disc is reduced more, and the next judgment is carried out, namely the temperature difference of the inner disc is calculated. And continuously acquiring data, wherein the temperature of the disc in the next period is 47.0 ℃, Z is-0.4 ℃, and if Z is less than 0 for m continuous periods (such as 10 periods), the frosting of the outer side of the air conditioner is judged, and the defrosting mode is entered.
