Hybrid power generation system for room air conditioner

Abstract

The invention provides a hybrid power generation system for a room air conditioner, comprising a photovoltaic solar power generation system connected with an air-conditioning system, wherein the solar power generation system is connected with an internal alternating current power system of the air-conditioning system in parallel through a grid-connected inverter of the solar power generation system, an air conditioner power socket of the air-conditioning system is plugged into a household power system, the household power system is connected with a power utilization load, the household power system is externally connected with the national utility grid through a power meter, the photovoltaic solar power generation system and the national utility grid provide hybrid power for the air-conditioning system in a preferred manner, and residual power generated by the photovoltaic solar power generation system is reversely supplied to the national utility grid. After the hybrid power generation system for the room air conditioner adopts the scheme, the photovoltaic solar power generation system and the internal alternating current power system of the air-conditioning system realize grid connection and supply power to the room air conditioner in a hybrid manner, and the residual power is directly fed to the household power system, so that the purposes of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a hybrid power generation system used by room air conditioners. Background technique [0002] Almost all existing room air conditioners are driven solely by conventional electricity provided by the public grid. With the exhaustion of energy sources, energy conservation and emission reduction are becoming more and more urgent. Currently, new and clean energy sources are used to replace conventional energy sources. It has been valued by all walks of life, and solar energy, as a clean energy source, is being used more and more widely, which meets the needs of the country's energy conservation and emission reduction policies. However, at present, photovoltaic solar power generation is relatively expensive, the power generation efficiency is not very high, and the use of room air conditioners is relatively large, so the use of photovoltaic solar energy in room air condi...
