Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the present invention provides a control method of an air conditioner, specifically a control method of a photovoltaic air conditioner, including the steps of:
the method comprises the steps that a photovoltaic air conditioning unit receives reservation information of a user;
and acquiring the return time of the user from the reservation information, and selecting a power supply control program corresponding to different return times to set the advanced starting time of the air conditioner. When a user arrives at home, the air conditioner is started for precooling in advance, and the user experience and the utilization efficiency of the air conditioner are improved.
Selecting the power supply control program corresponding to different return times to set the advanced starting time of the air conditioner specifically comprises the following steps:
the return time of the user is a preset daytime period; the preset daytime period may be a period of hours after the day comes, and a period of energy charging is reserved, for example, 10 o 'clock to 6 o' clock afternoon, and the specific time may be set according to actual conditions.
Judging whether the power supply power P1 of the photovoltaic power supply unit is greater than or equal to the rated operation power P2 of the air conditioner, if so, starting the air conditioner in advance for a preset time T1; if not, the power of the photovoltaic power supply unit is insufficient, the time for starting the air conditioner in advance is calculated through a preset power interpolation calculation formula, so that the starting time is delayed, and the air conditioner is prevented from being shut down due to the insufficient power of the photovoltaic power supply unit.
The preset power interpolation formula is T1 ' = ƞ T1(P2-P1)/P1, T1 ' is the time of starting up in advance, ƞ is a correction coefficient, and in a specific embodiment, the maximum value of T1 ' is 60 min. The correction factor ƞ increases with decreasing P1/P2 as follows:
| power ratio Ψ (P1/P2) | d≤Ψ＜1 | c≤Ψ＜d | b≤Ψ＜c | …… | 0＜Ψ＜a |
| Correction factor ƞ | X1 | X2 | X3 | …… | Xn |
Since the required cooling time is greatly increased along with the decrease of the power ratio Ψ, the increase ratio thereof is non-linear, and therefore, the correction coefficient ƞ needs to be increased, and the correction coefficient ƞ has a range of: ƞ is greater than or equal to 1.
The specific selection steps of the correction factor ƞ are as follows: dividing a plurality of power ratio ranges in advance, presetting a correction coefficient corresponding to each power ratio range, judging the power ratio range in which the current power ratio P1/P2 is positioned, and selecting the correction coefficient corresponding to the power ratio range as the correction coefficient of a preset power interpolation calculation formula.
The step of selecting the power supply control program corresponding to different return time to set the advanced start-up time of the air conditioner further comprises the following steps:
the return time of the user is a preset night time period;
judging whether the electric energy N of the energy storage unit is greater than or equal to the rated operation electric energy P of the air conditioner when the return time is reached, if so, starting the air conditioner for a preset time T2 in advance; if not, the time for starting the air conditioner in advance is calculated through a preset energy storage interpolation calculation formula, so that the starting time is delayed, and the air conditioner is prevented from being shut down before a user arrives at home due to insufficient power of the energy storage unit.
The preset energy storage interpolation calculation formula is as follows: t2 '= T2N/M, T2' is the time of starting up in advance, and M is the electric energy when the energy storage unit is full. The minimum value of T2' is 10 min. The time for starting the air conditioner in advance is shortened according to the electric energy ratio, and the air conditioner is ensured to be in a starting state when a user arrives at home.
In both methods, an advanced starting time is obtained according to the interpolation calculation method when the electric quantity is insufficient, and the remaining electric quantity can be supported to the home time of the user, namely the return time.
It should be noted that the specific numerical calculation principle of P1 is as follows: the weather linkage feeds back the illumination intensity of the return time preset by the user, and the specific numerical value of P1 can be judged by referring to a comparison table of the illumination intensity and the photovoltaic panel generated power obtained by factory test. T1 and T2 are the time when the air conditioner reaches the preset cooling or heating state when the electric quantity is sufficient (the photovoltaic electric energy is sufficient to meet the electric quantity required by the operation power of the air conditioning unit), and the time can be determined in advance according to the specific cooling or heating target value.
In order to further improve the utilization efficiency of the photovoltaic power supply unit, the invention also comprises the following steps:
when the corresponding control program of the daytime period is operated, the away-from-home time of the user is calculated according to the return time of the user (the air conditioner is closed when the user goes out, namely the out-of-home time of the user is defined when the air conditioner is closed, the away-from-home time of the user is determined to be the away-from-home time of the user), whether the away-from-home time is greater than the preset time T3 corresponding to the daytime period is judged, if yes, the photovoltaic power supply unit supplies power to the energy storage unit, and when the electric quantity of the energy storage unit reaches the preset storage quantity, the power supply unit supplies power to a power grid (a power supply network), and if not, the power supply mode is selected according to the power supply power of the photovoltaic power supply unit. The electric energy utilization of the photovoltaic power supply unit is ensured to be maximized.
The method for selecting the power supply mode according to the power supply power of the photovoltaic power supply unit comprises the following steps:
judging whether the power supply power of the photovoltaic power supply unit is greater than the rated operation power of the air conditioner, if so, the photovoltaic power supply unit simultaneously supplies power to the air conditioner and the energy storage unit, and the electric quantity of the energy storage unit supplies power to the power grid (network feeding) when reaching the preset storage quantity; if not, the photovoltaic power supply unit only supplies power to the air conditioner.
When a corresponding control program in the night time period is operated, calculating the leaving time of the user according to the return time of the user (the air conditioner is closed when the user goes out, namely the leaving time of the user is defined when the air conditioner is closed, and the leaving time to the return time is defined as the leaving time of the user), judging whether the leaving time is greater than the preset time T4 corresponding to the night time period, if so, supplying power to the energy storage unit by the photovoltaic power supply unit, and supplying power to the power grid when the electric quantity of the energy storage unit reaches the preset reserve; and if not, the energy storage unit is used for supplying power to the unit. The electric energy utilization of the photovoltaic power supply unit is ensured to be maximized.
The invention also provides an air conditioner, and the control method is used for controlling the early starting time of the air conditioner.
Specifically be photovoltaic air conditioner includes: the photovoltaic power supply unit is connected with the inverter to supply power. The specific connection mode is the conventional common mode, and the specific connection mode can be seen in fig. 2.
