In an embodiment of the present application, based on the difference, the control performs at least one of: whether control boiler is above-mentioned room heating, whether control fluorine pump air conditioner enters the refrigeration mode, include: controlling only the boiler to heat the room when the difference is less than zero; and after the boiler heats the room for a first preset time period and when the difference value is greater than or equal to zero, controlling the boiler to heat the room and controlling the fluorine pump air conditioner to enter a cooling mode. That is, when the current temperature in the room is lower than the predetermined temperature, the room needs to be heated, so that the temperature in the room reaches the predetermined temperature, for example, the predetermined temperature is 25 ℃, the current temperature in the room is 20 ℃, and the boiler is turned on to heat the room, so that the temperature in the room is raised to the predetermined temperature; after the boiler heats a room for a first preset time period, and the real-time temperature is greater than or equal to the preset temperature, the fluorine pump air conditioner is controlled to enter a refrigeration mode to start refrigeration, for example, after the boiler heats the room for 3min, the temperature in the room is greater than 25 ℃, that is, the temperature in the room is higher, the fluorine pump air conditioner needs to be started to refrigerate the room, and the temperature in the room is kept at a comfortable temperature under the combined control of the boiler and the fluorine pump air conditioner.
After controlling the fluorine pump air conditioner to enter the cooling mode, in order to control the temperature in the room to be kept at a comfortable temperature, the fluorine pump air conditioner needs to be controlled more specifically, in an embodiment of the present application, after controlling the fluorine pump air conditioner to enter the cooling mode, the method further includes: under the condition that the difference value is larger than or equal to a first threshold value and smaller than or equal to a second threshold value, at least controlling an internal unit of the fluorine pump air conditioner to enter an up-conversion mode; and after the internal machine of the fluorine pump air conditioner operates in the frequency increasing mode for a second preset time period, and under the condition that the difference value is greater than the second threshold value and less than or equal to a third threshold value, controlling the rotating speed of the internal machine of the fluorine pump air conditioner to be unchanged, wherein the first threshold value is less than the second threshold value, and the second threshold value is less than the third threshold value. When the fluorine pump air conditioner is controlled to enter a refrigeration mode, the indoor temperature is proved to be too high and needs to be cooled, so that the frequency-increasing fan is needed to ensure that the refrigeration effect is better to achieve the purpose of cooling, and under the action of frequency-increasing of the fan and heating of the boiler, the temperature in the room meets the condition that the difference value is larger than the second threshold value and is smaller than or equal to the third threshold value, namely the temperature in the room reaches a comfortable state.
In a more specific embodiment of the present application, after controlling the fluorine pump air conditioner to enter the cooling mode, the method further includes: and controlling the frequency of the inner unit of the fluorine pump air conditioner to change according to a function when the difference value is greater than or equal to a first threshold value and less than or equal to a second threshold value:
wherein, as shown in FIG. 4, T1Representing a real-time temperature, T representing a predetermined temperature, X representing a first threshold, Z representing a second threshold, Y representing a third threshold, N0Is the minimum value of the rotating speed of the inner fan when T1-T < X, N1The maximum rotating speed of the inner fan is adopted, namely, the frequency of the inner fan is controlled by adopting a pure frequency reduction or frequency increase mode, and the frequency of the inner fan changes along with the change of the difference value, so that the temperature in a room is adaptively adjusted, and the temperature in the room meets the requirement of comfort.
In an embodiment of the application, after controlling the fluorine pump air conditioner to enter the cooling mode, the method further includes: controlling the fluorine pump air conditioner to exit the refrigeration mode under the condition that the difference value is smaller than a first threshold value; after the fluorine pump air conditioner exits the refrigeration mode for a third preset time period, and under the condition that the difference value is greater than or equal to the first threshold value and less than or equal to a second threshold value, controlling the fluorine pump air conditioner to reenter the refrigeration mode, and controlling an internal machine of the fluorine pump air conditioner to enter an up-conversion mode; and after the internal machine of the fluorine pump air conditioner operates in the frequency increasing mode for a fourth preset time period, and under the condition that the difference value is greater than the second threshold value and less than or equal to a third threshold value, controlling the rotating speed of the internal machine of the fluorine pump air conditioner to be unchanged, wherein the first threshold value is less than the second threshold value, and the second threshold value is less than the third threshold value. For example, when the difference is less than-5, it indicates that the temperature in the room is too low at this time, and refrigeration is not needed, i.e. the fluorine pump air conditioner is controlled to exit the refrigeration mode; after the operation is carried out for 3min, under the condition that the difference value is greater than or equal to-5 and less than or equal to-2, the fluorine pump air conditioner is controlled to reenter the refrigeration mode, and the inner machine of the fluorine pump air conditioner is controlled to enter the frequency increasing mode, so that the situation that the temperature in a room is too high under the heating action of a boiler, namely, the temperature in the room is required to be adjusted from an uncomfortable state to a comfortable state, is not instantaneous; when the temperature in the room returns to the comfortable state again, the rotating speed of the inner machine of the fluorine pump air conditioner is controlled to be unchanged, so that the temperature in the room is maintained in the comfortable state.
In an embodiment of the application, after controlling the fluorine pump air conditioner to enter the cooling mode, the method further includes: under the condition that the difference value is larger than a third threshold value, increasing the opening degree of an electronic expansion valve of an internal unit of the fluorine pump air conditioner; stopping increasing the opening degree of the internal machine electronic expansion valve under the condition that the difference value is less than or equal to the third threshold value after the fluorine pump air conditioner operates for a fifth preset time period; and after the fluorine pump air conditioner operates for a sixth preset time period, and under the condition that the difference is greater than a second threshold value and less than or equal to a third threshold value, controlling the rotating speed of an internal machine of the fluorine pump air conditioner to be unchanged, wherein the second threshold value is less than the third threshold value. For example, when the difference is greater than 2, for example, when the difference is 5, it indicates that the temperature in the room is too high at this time, and the temperature needs to be reduced to return to a comfortable state, however, at this time, the requirement cannot be met only by controlling the frequency of the inner unit of the fluorine pump air conditioner, that is, the requirement cannot be met only by increasing the frequency of the inner unit of the fluorine pump air conditioner, and at this time, the opening degree of the electronic expansion valve of the inner unit needs to be increased, that is, the refrigerant quantity needs to be increased to reduce the temperature; stopping increasing the opening degree of the internal machine electronic expansion valve when the temperature decreases to a difference value smaller than or equal to the third threshold value; and after the operation is carried out for 3min again, under the condition that the difference value is greater than the second threshold value and less than or equal to the third threshold value, the rotating speed of the inner machine of the fluorine pump air conditioner is controlled to be unchanged, so that the temperature in the room is maintained in a comfortable state.
In an embodiment of the application, after controlling the fluorine pump air conditioner to enter the cooling mode, the method further includes: and controlling the rotation speed of the internal unit of the fluorine pump air conditioner to be unchanged when the difference is larger than a second threshold value and smaller than or equal to a third threshold value, wherein the second threshold value is smaller than the third threshold value. Namely, after the fluorine pump air conditioner enters the cooling mode, the temperature in the room is originally kept in a comfortable state, and the temperature in the room is kept in the comfortable state without adjusting the rotating speed of an inner machine of the fluorine pump air conditioner. If the temperature of the subsequent room changes, corresponding adjustment is carried out.
From the analysis of the above embodiments, after the fluorine pump air conditioner enters the cooling mode, there are several situations of the current temperature in the room: the difference is less than a first threshold; the difference is greater than or equal to a first threshold and less than or equal to a second threshold; when the difference is larger than a second threshold value and smaller than or equal to a third threshold value; the difference is greater than a third threshold; no matter what the current temperature in the room is, it is required to realize that the current temperature in the room satisfies the condition that the difference value is greater than the second threshold value and less than or equal to the third threshold value, that is, the temperature in the room is maintained in a comfortable state through the dual control of the boiler and the fluorine pump air conditioner, and the above embodiment of the present application realizes the closed-loop control of the temperature in the room.
The embodiment of the present application further provides a temperature control device, and it should be noted that the temperature control device of the embodiment of the present application may be used to execute the method for temperature control provided by the embodiment of the present application. The following describes a device for temperature control provided in an embodiment of the present application.
