Problems solved by technology

[0003] In order to overcome at least to a certain extent that when the power generated by the photovoltaic power generation side is less than the electric energy required by the photovoltaic air conditioner, the photovoltaic air conditioner needs to obtain electric energy from the grid side, and the electric energy obtained from the grid side needs to be converted multiple times by rectifiers and inverters. Supplying power to the centrifugal compressor will cause energy efficiency and low conversion efficiency during the conversion process, resulting in energy waste. This application provides a photovoltaic air conditioner power supply circuit, power supply control system and photovoltaic air conditioner

Abstract

The invention relates to a photovoltaic air conditioner power supply circuit, a power supply control system and a photovoltaic air conditioner. The photovoltaic air conditioner power supply circuit comprises a bypass and a control switch arranged on the bypass, one end of the bypass is connected with a power grid side, and the other end is connected with a centrifugal compressor. The control switch is used for controlling the connection or disconnection of the bypass so as to control the connection or disconnection of the power grid side and the centrifugal compressor. According to the presentinvention, the centrifugal compressor of a photovoltaic air conditioner can directly take electricity from the power grid side without twice conversion of a rectifier and an inverter, the electric energy utilization efficiency is improved, and energy waste is avoided.

Description

technical field [0001] The application belongs to the technical field of photovoltaic air conditioners, and in particular relates to a photovoltaic air conditioner power supply circuit, a power supply control system and a photovoltaic air conditioner. Background technique [0002] The schematic diagram of the centrifugal compressor control system of photovoltaic air conditioner is as follows figure 1 As shown, it mainly includes the photovoltaic power generation side, the grid side, the onboard converter and the centrifugal compressor, and the onboard converter includes a rectifier and an inverter. When the power generated by the photovoltaic power generation side is less than the electric energy required by the photovoltaic air conditioner, the photovoltaic air conditioner needs to obtain electric energy from the grid side, and the electric energy obtained from the grid side needs to be converted multiple times by rectifiers and inverters before it can supply power to the c...
