The invention discloses a compressor start method for frequency conversion equipment. The method comprises the steps that a set temperature is received, and a target frequency of operating of a compressor is obtained according to the set temperature and the indoor and outdoor ambient temperature; the minimum rated frequency and the maximum rated frequency of the compressor are obtained, the interval between the minimum rated frequency and the target frequency serves as a first interval, and the interval between the target frequency and the maximum rated frequency serves as a second interval; at least one frequency is selected from the first interval and / or the second interval and used as the test frequency, and the frequency of the compressor is adjusted to the test frequency for operating; and after the compressor operates at the test frequency for the preset time length, the compressor frequency is adjusted to the target frequency from the test frequency for operating. In this way, the fast start of the compressor is achieved, it is avoided that the compressor operates at the target frequency after operating on all frequency platforms for the set time length, and the start time of the system is shortened. The invention further discloses a compressor start device for the frequency conversion equipment.
Description
technical field [0001] The present invention mainly relates to the technical field of compressor start-up for frequency conversion equipment, and in particular, relates to a compressor start-up method and device for frequency conversion equipment. Background technique [0002] With the popularization of frequency conversion technology, there are more and more equipment using frequency conversion technology such as air conditioners and refrigerators. Frequency conversion technology can significantly improve the comprehensive capacity and energy efficiency of frequency conversion equipment. The frequency conversion equipment divides the frequency into different levels according to its variable frequency range. When the compressor used for the frequency conversion equipment is started, it needs to run for a set period of time on each specified frequency platform from low to high for use in Ensure the reliability of system operation. This prolongs the start-up time of the syste...
