Example 1
Fig. 1 is a flowchart of an anti-condensation control method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S101, acquiring temperature data of three continuous time periods before the current time; wherein, three continuous time quantum divide into according to time front and back: a third time period, a second time period and a first time period, wherein the first time period is continuous with the current time;
step S102, determining dew point temperature and floor temperature according to temperature data of three continuous time periods;
step S103, judging whether a condensation condition is met according to the dew point temperature and the floor temperature;
and step S104, if so, determining a target high pressure according to the dew point temperature and the floor temperature, and controlling the operation of the compressor according to the target high pressure.
When the dew point temperature of the air is higher than the floor temperature, condensation can occur on the floor, so that the data of the dew point temperature and the floor temperature are accurate, the current time is pushed forward, three time periods are set, and the dew point temperature and the floor temperature which are more accurate are calculated according to temperature parameters in the three time periods. The temperature participation of the three time periods specifically comprises: acquiring a dew point temperature of a first time period; acquiring the temperature variation of a second time period; and acquiring the average ambient temperature of the third time period.
When more accurate dew point temperature and floor temperature are calculated according to temperature parameters in three time periods, the embodiment provides a preferred embodiment, that is, an average value of the dew point temperatures in the first time period is calculated and determined as the dew point temperature at the current moment; calculating to obtain a correction value according to the temperature variation of the second time period; and calculating the floor temperature according to the average ambient temperature of the third time period and the correction value. Based on this, can guarantee when the monitoring floor condensation appears, the data that consults are more accurate to can accurately monitor whether the condensation appears in the floor in real time, improve user experience.
Then, judging whether a condensation condition is met or not according to the dew point temperature and the floor temperature, and specifically calculating a temperature difference between the dew point temperature and the floor temperature; and if the temperature difference is larger than 0, judging that the condensation condition is met. When the floor condensation condition is judged to be met, the floor condensation condition can be confirmed to possibly occur, and corresponding condensation prevention measures need to be taken. For example, floor heating is turned on.
When the floor heating is started, the target high pressure of the compressor needs to be controlled, and the floor heating is guaranteed to achieve a better condensation removing effect.

The temperature difference can be used as a characterization parameter of a condensation severity program, when the temperature difference is larger, the condensation problem is more serious, and when the temperature difference is smaller, the condensation problem is less serious. Therefore, in general, the larger the temperature difference, the larger the corresponding high-pressure correction value.
After the condensation condition is met, calculating to obtain a preferable target high pressure, triggering to start a floor heating mode, and controlling the operation of a compressor according to the target high pressure to execute condensation prevention operation; and after the operation is carried out for a preset time, ending the condensation preventing operation.

When the dew point temperature of the air is higher than the temperature of the floor, the floor begins to be condensed, and based on the theoretical basis, the dew point temperature of the point A is equal to the average dew point temperature T of the stage I Ⅰ-L To determine the floor temperature according to the average ambient temperature (T) of stage III Ⅲ-av ) And calculating a corrected value by using the temperature variation of the stage II, and recording the corrected value as X. The floor temperature is noted: t is d-A 。

Wherein the correction value X = (T) Ⅰ-av －T Ⅲ-av ) Lambda, where lambda is preferably 2. Wherein, T Ⅰ-av Is the average ambient temperature of stage i.
And step S203, calculating the difference delta T between the dew point temperature and the floor temperature, and correcting the target high pressure of the unit according to the difference.
Delta T is the difference value between the dew point and the temperature of the floor, when delta T is detected to be larger than 0, a floor heating mode is started, the temperature of the floor is increased, the unit operation target high voltage is controlled to be Tc mesh, the unit target high voltage Tc mesh = Tc base + Tc correction, wherein the Tc base is determined by the environmental temperature and the starting load and is a preset value of a manufacturer, and the Tc correction is performed by the following steps:
meter Δ T = T Ⅰ-L －T d-A (the calculated value of Δ T may beAs a characteristic parameter of the procedure for the condensation severity, when the difference is larger, the more serious the condensation problem is, and the smaller the difference, the less serious the condensation problem is). Examples are as follows:
when the delta T is larger than or equal to a, the high-voltage correction value is a1;
when b is less than or equal to delta T and less than a, the high-pressure correction value is b1;
when delta T is more than or equal to 0 and less than b, the high-pressure correction value is c1;
preferably, a =7, b =3, a1=3, b1=1, c1=0.
And step S204, the unit performs corresponding output control on the compressor according to the target high pressure.
And S205, raising the temperature of the floor, and finishing the anti-condensation control after the unit runs for time t 4. The operating time t4 can be a factory preset value, preferably t4=2h.
