Problems solved by technology

The power control method of the traditional air conditioner is to control the power of the compressor by detecting the input AC voltage and input AC current of the mains grid (limited frequency control). However, for solar air conditioners, it is controlled by the mains grid and solar panels. Provide electric energy together, so when this method is used in solar air conditioners, it will lead to inaccurate power detection, which will lead to unreasonable control of the compressor, failure to achieve the control target, and even affect the stability of the electric control

Abstract

The invention discloses a solar air conditioning system and a power control method and a device thereof. The power control method comprises the following steps: a variation of direct-current bus voltage of a compressor is obtained; a target frequency of the compressor sent by an indoor unit is received; when the variation of the direct-current bus voltage is lower than a first preset variation, and the target operation frequency of the compressor sent by the indoor unit is higher than a preset target frequency of the compressor, a temperature value of a first inversion module is further obtained; then, a present target frequency of the compressor is adjusted according to the temperature value of the first inversion module; and the compressor is controlled according to the adjusted target frequency. Under the precondition of guaranteeing stable operation of an air conditioner, solar energy can be fully used for realizing the power control.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a power control method for a solar air conditioning system, a power control device for a solar air conditioning system, and a solar air conditioning system with the power control device. Background technique [0002] Generally, an air conditioner is composed of an indoor unit and an outdoor unit, and the main energy for its work comes from the mains power grid. For the outdoor unit, the input of the mains power grid is processed by the filter circuit, the rectifier circuit, and the PFC (Power Factor Correction, power factor correction) circuit, and finally converted into direct current and stored at both ends of the electrolytic capacitor, and the main component of the outdoor unit, the compressor The energy required for the operation of the fan, fan, etc. comes from the electrolytic capacitor. [0003] In order to save energy, a solar air conditioner began to appear, t...
