Embodiment 1

[0018] Embodiment 1: A control method for limiting power of an inverter air conditioner.

[0019] Such as figure 1 As shown, a power limiting control method of an inverter air conditioner, the specific steps are as follows:

[0020] Step 1: Read the outdoor ambient temperature T outer ring, and the air conditioner operating mode.

[0021] Step 2: According to the outdoor ambient temperature and the operating mode of the air conditioner, the ambient temperature is divided into areas. The divided areas can be adjusted according to specific experiments, and the rated power values ​​are relatively close to the same interval, so as to avoid the rated power measured in the same interval. The value difference is large. details as follows:

[0022] When T outer ring <-6°C, the air conditioner operating mode is heating mode, the rated current threshold is 13.4A, the air conditioner operating mode is non-heating mode, and the rated current threshold is 4.5A;

[0023] When -6°C ≤ T o...

Embodiment 2

[0040] Embodiment 2: a storage medium.

[0041] A storage medium is used for storing a computer program, and when the computer program is invoked by a processor, the method for controlling the limited power of an inverter air conditioner described in Embodiment 1 is implemented.

Embodiment 3

[0042] Embodiment 3: a kind of air conditioner.

[0043] An air conditioner includes a processor and a memory, the memory is used to store a computer program, and when the computer program is invoked by the processor, the method for controlling power limitation of an inverter air conditioner described in Embodiment 1 is implemented.

Abstract

The invention provides a variable frequency air conditioner power limiting control method, a storage medium and an air conditioner. After an air conditioning unit is started for operation, a current of a complete machine is detected in real time, and a current value is obtained; whether the an air conditioning unit needs to conduct frequency lowering operation or not is judged by analyzing the current value of the complete machine, under the condition that the frequency of a compressor of the air conditioning unit is lowered to the minimum frequency and still cannot meet the power reduction requirement, by recording the current value at the minimum operation frequency after frequency lowering, the stop time capable of meeting the requirement for the stop power is calculated, and the compressor is controlled to stop according to the top time. Frequency lowering is controlled by detecting the current, when the requirement still cannot be met after operation is conducted at the lowest frequency through frequency lowering, within the required time, the total energy consumption of the compressor operating at the lowest frequency is equal to the total energy consumption required by a power reduction mode, the total stop time of the compressor only stopping once is calculated, multiple times of starting and stopping are avoided, and the comfort of a user and the reliability of the compressor are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to a method for controlling power limitation of an inverter air conditioner, a storage medium and an air conditioner. Background technique [0002] At present, the market has mandatory restrictions on the operating power of air conditioners, and it is a necessary condition for the access of air conditioners in the form of regulations or standards. For example, through a specific device to input control signals to the air conditioner, the total energy consumption of the air conditioner during the period of responding to this signal should not exceed K% of the normal operation under the same working conditions. The current common practice is to take the nominal rated power of the air conditioner as the benchmark, and control the power of the air conditioner by a percentage reduction on this benchmark. This approach has the following problems: 1) The normal operating p...
