Aiming at the problem that the energy saving performance and the user comfort are difficult to meet simultaneously when the power is reduced due to the fact that the outdoor environment temperature factor is not considered when the conventional air conditioner is in power reduction operation, the embodiment provides a control method of the air conditioner, as shown in a control flow chart shown in fig. 1, the control method of the embodiment comprises steps S1-S4, wherein:
s1, obtaining the indoor environment temperature TInner partOutdoor ambient temperature TOuter coverUser-set temperature TIs provided with；
S2, calculating the indoor environment temperature TInner partWith a user-set temperature TIs provided withAnd the difference Δ T1, and the indoor ambient temperature TInner partWith outdoor ambient temperature TOuter coverΔ T2, Δ T1 ═ TInner part-TIs provided with|，ΔT2＝|TOuter cover-TInner part|；
S3, determining whether to perform power down control according to the difference value delta T1 and the difference value delta T2;
and S4, when power reduction control is needed, determining the frequency of the compressor and the rotating speed of the external fan after the power reduction operation of the air conditioner according to the difference value delta T1 and the difference value delta T2.
In this embodiment, since the difference between the outdoor ambient temperature and the indoor ambient temperature is different, and the energy consumption is different when the same set temperature condition is achieved, the reduction degree of the compressor operating frequency and the external fan rotating speed is different when the air conditioner reduces the power. The embodiment combines the outdoor environment temperature, the indoor environment temperature and the set temperature to determine the frequency of the compressor and the rotating speed of the outer fan after the power reduction operation when the air conditioner is controlled to reduce the power, so that the energy consumption is effectively saved on the premise of ensuring the comfort experience of a user. This implementationIn the example, in the cooling mode, Δ T1 ═ TInner part-TIs provided with，ΔT2＝TOuter cover-TInner part(ii) a In the heating mode, Δ T1 ═ TIs provided with-TInner part，ΔT2＝TInner partTOuter cover。
Further optionally, in step S3, when one of the following two determination conditions is satisfied, it is determined that the power down control is required, a1, Δ T1 ≦ the first set temperature; b1,. DELTA.T 2 > a second set temperature.
In this embodiment, when Δ T1 is less than or equal to the first set temperature, it indicates that the indoor ambient temperature is close to the set temperature, and the air conditioner needs little further cooling or heating, and only needs to maintain the current indoor temperature, and at this time, the air conditioner can be controlled to operate with reduced power. When the delta T2 is greater than the second set temperature, the difference between the outdoor ambient temperature and the indoor ambient temperature is larger, and the amount of cooling or heating required for reaching the set temperature is less, and the air conditioner can be controlled to operate at reduced power.
When the air conditioner operates with reduced power, there are three situations:
in the first case: when the following two judgment conditions are satisfied simultaneously, namely: a1 and delta T1 are less than or equal to a first set temperature; b2 and delta T2 are less than or equal to a second set temperature, the compressor is controlled to reduce the frequency to the first frequency, and the rotating speed of the outer fan is reduced to the first rotating speed.
In the second case: when the following two judgment conditions are satisfied simultaneously, namely: a1 and delta T1 are less than or equal to a first set temperature; b1 and delta T2 are higher than a second set temperature, power reduction control is judged to be needed, the compressor is controlled to reduce the frequency to a second frequency, and the rotating speed of the outer fan is reduced to a second rotating speed; the second frequency is less than the first frequency, and the second rotating speed is less than the first rotating speed.
In the third case: when the following two judgment conditions are simultaneously met, namely A2, delta T1 > a first set temperature, and B1, delta T2 > a second set temperature; judging that power reduction control is needed, controlling the compressor to reduce the frequency to a third frequency, and reducing the rotating speed of the external fan to a third rotating speed; the first frequency is less than the third frequency, and the first rotating speed is less than the third rotating speed.
In this embodiment, as shown in the flowcharts of fig. 2 and fig. 3, when Δ T1 is less than or equal to the first set temperature, it indicates that the indoor environment temperature is close to the set temperature, the air conditioner needs little further cooling or heating, and only needs to maintain the current indoor temperature, and at this time, the air conditioner can be controlled to operate with reduced power. Because the energy consumption is different when the same set temperature is reached when the temperature difference between the outdoor environment temperature and the indoor environment temperature is different, the frequency of the compressor and the rotating speed of the external fan are determined according to the temperature difference delta T2 between the outdoor environment temperature and the indoor environment temperature,
when the delta T2 is less than or equal to the second set temperature, the temperature difference between the indoor environment temperature and the outdoor environment temperature is smaller, and the energy consumption of the air conditioner to further reduce the indoor temperature under the smaller temperature difference is higher than that under the condition of larger temperature difference, therefore, on the premise that the delta T1 is less than or equal to the first set temperature, in order to ensure the comfort of a user, the frequency of the compressor when the delta T2 is less than or equal to the second set temperature is higher than that when the delta T2 is greater than the second set temperature, and the regulation of the rotating speed of the external fan is far away from the same principle as the regulation of the frequency of the compressor.
When the delta T2 is greater than the second set temperature, the difference between the indoor ambient temperature and the outdoor ambient temperature is larger, the energy consumption required for reaching the set temperature of a user is less, and the power-down operation of the air conditioner can be controlled. Because the energy consumption is different when the indoor environment temperature is different and the same set temperature is reached, the frequency of the compressor and the rotating speed of the outer fan are determined according to the temperature difference delta T1 between the indoor environment temperature and the set temperature. Under the premise that the delta T2 is greater than the second set temperature, in order to ensure the comfort of a user, when the delta T1 is greater than the first set temperature, the difference between the indoor environment temperature and the set temperature is large, and the operation frequency of the compressor needs to be higher than that when the delta T1 is less than the first set temperature, so that the indoor environment temperature can be quickly adjusted. When the delta T1 is larger than the first set temperature, the inner fan is controlled to increase the running speed in order to further rapidly reduce the indoor temperature.
Further optionally, the first set temperature is less than or equal to 2 ℃, and the second set temperature is less than or equal to 3 ℃.
The present embodiment also proposes a control device of an air conditioner, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions, when the one or more processors execute the program instructions, the one or more processors are configured to implement the method according to any one of the above.
The present embodiments also propose a non-transitory computer-readable storage medium having stored thereon program instructions for implementing the method according to any one of the above when the program instructions are executed by one or more processors.
The present embodiment also proposes an air conditioner employing the non-transitory computer-readable storage medium according to any one of the above.
Further optionally, the air conditioner of this embodiment includes an energy storage device, and the energy storage device supplies power to the air conditioner during a preset peak period of power consumption or during a power outage, and charges the air conditioner during a preset peak period of power consumption.
Fig. 4 is a schematic diagram of the air conditioner providing electric energy to the air conditioner at different operation periods, in the diagram, two modules for supplying energy to the air conditioner during normal operation are provided, one is an energy storage device, and the other is an air conditioner electrical box, and the difference between the two modules is that the air conditioner electrical box directly consumes the mains supply for the air conditioner to operate during the operation, and the energy storage device can be used for the air conditioner to operate during the peak period of the use of the mains supply or under the condition that the mains supply is powered off. And in the low peak period of power utilization, the air conditioner consumes the commercial power to operate, and in this period, the commercial power synchronously charges and stores energy for the energy storage device.
Fig. 5 is a schematic diagram illustrating that the commercial power charges the energy storage device during the low-peak power consumption period, that is, when the air conditioner picks up the low-peak power consumption period set by the system, the energy storage device uses the commercial power to store energy for itself. However, in the period of low peak of electricity consumption, the starting operation system of the air conditioner can automatically select to preferentially use the mains supply for energy supply, so that the purpose of controlling is to ensure the service life of the energy storage device and avoid the influence on the service life of the energy storage device when the energy storage device is continuously used for a long time. And in the low-peak electricity utilization period, the mains supply synchronously charges the energy storage device for energy storage. During peak power utilization or power limitation, the air conditioning system can select to use the energy storage device to supply energy to the air conditioner for operation according to the received operation time. In addition, when the commercial power cannot be used, namely under the condition of power failure, the energy storage device can be used for ensuring the normal use of the air conditioner.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
