Example Embodiment

[0016] Example 1:

[0017] Before describing the control method of the present invention, the system principle diagram of the air conditioner is described in order to better understand the present invention. With the help of figure 1 The system principle diagram of the air conditioner of the present invention is schematically illustrated. The air conditioner in the embodiment of the present invention has a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, an expansion valve 6, a stop valve 52, and an indoor heat exchange in order through pipelines. The device 4, the shut-off valve 51, passes through the shut-off valve 51 and communicates with one of the ports of the four-way valve. The indoor unit side is provided with an indoor temperature sensor 42 for detecting indoor ambient temperature, and the indoor unit heat exchanger 4 is provided with an inner panel temperature sensor 43 for detecting the temperature of the indoor heat exchanger 4, that is, the inner panel...

Abstract

The invention provides a control method for high-frequency start of an inverter air conditioner. The method includes steps that when an external ambient temperature meets a first pre-set temperature,a target frequency of a compressor is compared with a set first limit frequency; when the target frequency of the compressor is bigger than or equal to the first limit frequency, the compressor is controlled to work at the first limit frequency for a second pre-set time and then work at a normal frequency; when the target frequency of the compressor is smaller than the first limit frequency, the compressor is controlled to upconvert to the target frequency at a set upconversion rate and maintain working at the target frequency for the second pre-set time, and then work at a normal frequency; and when the target frequency of the compressor is smaller than a set second limit frequency, the compressor is controlled to work at a normal frequency. According to the method, the customer needs forrapid cooling and heating can be met under a bad working condition, so that the customer satisfaction is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a control method for high-frequency start-up of an inverter air conditioner and the air conditioner. Background technique [0002] Air conditioners are equipment for air quality adjustment. With the development of air conditioner technology, people have higher and higher requirements for air conditioners, especially in harsh working conditions. High-frequency operation can quickly meet the customer's indoor temperature requirements. Most of the related technologies use the difference between the ambient temperature and the target temperature as a basis to control the air conditioner to quickly reach the target temperature. Although this technology can achieve high-frequency operation, but in the control process The air conditioner will stay on a certain frequency platform for a long time, which will prolong the time to reach the target temperature, which cannot meet the user's pur...
