Problems solved by technology

[0003] After the inverter receives the start-up command, it will start cooling and heating according to the control logic requirements. After the compressor starts, in order to ensure the stable operation of the compressor, set the frequency operation platform of the compressor. After the start-up conditions are met, the compressor will start. The logic requires the gradient to run incrementally. In this control mode, the compressor will run directly to the highest frequency after running the transitional platform, and will run to the frequency reduction condition under the highest frequency condition (up to temperature, limit frequency reduction protection, etc.), This mode is equivalent to the unit continuously operating at high frequency, and the unit outputs at the maximum power. Although the best operating effect can be achieved, the power consumption increases significantly, which does not meet the current energy-saving and environmental protection requirements.
At the same time, it continues to run at the highest frequency for a long time, resulting in low operating comfort and affecting the experience

no. 1 example

[0047] see in conjunction figure 1 and figure 2 , This embodiment provides an air conditioner frequency control method, which is used to control the frequency of the compressor in the air conditioner, so as to realize the functions of energy saving, environmental protection and comfortable air flow. The air conditioner includes an air conditioner body, a compressor arranged in the air conditioner body, and a controller electrically connected to the compressor.

[0048] The air conditioner frequency control method provided in this embodiment includes the following steps:

[0049] S1: Obtain the indoor temperature Tai.

[0050] Specifically, after the compressor is started, the target temperature is set manually or automatically, the indoor temperature Tai is detected by the first temperature detector installed indoors, and the generated temperature signal is transmitted to the controller. After the controller obtains the indoor temperature signal, it compares it with the se...

Abstract

The invention provides an air conditioner frequency control method and an air conditioner, and relates to the technical field of air conditioners. A limiting frequency Fmax is set by using a first difference value delta T1 between an indoor temperature Tai and a set temperature Ts; and a compressor is controlled to operate at the limiting frequency Fmax to prevent operation of the air conditionerat the highest frequency under any conditions. Compared with the prior art, the operation frequency upper limit of the compressor can be determined according to the difference value between the indoortemperature and the set temperature, namely actual refrigeration / heating load, so that the cold / heat demands can be met, and meanwhile, the energy consumption can be saved as much as possible.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner frequency control method and an air conditioner. Background technique [0002] The frequency conversion air conditioner can adjust the operating frequency of the compressor according to the change of the cooling and heating load, thereby controlling the cooling (heating) capacity output of the air conditioner. Compared with fixed-frequency air conditioners, it has the advantages of energy saving and good cooling and heating effects, and is more and more favored by the market. [0003] After receiving the start-up command, the inverter will start cooling and heating according to the control logic requirements. After the compressor is started, in order to ensure the stable operation of the compressor, set the frequency operation platform of the compressor. After the start-up conditions are met, the compressor will start. The logic requires the gradient ...
