Air conditioner and its power supply system and power supply method

Abstract

The invention discloses an air conditioner, and a power supply system and a power supply method thereof, and relates to the field of air conditioners. The power supply system of the air conditioner comprises a storage battery and a power control unit, wherein the power control unit is used for charging the storage battery through a power grid in the electric energy trough time period of the power grid and controlling the storage battery to supply power to the air conditioner in the electric energy crest time period of the power grid and also controlling the storage battery to supply power to the power grid. By the additional arrangement of energy storage equipment in the power supply system of the air conditioner, energy storage can be executed in the electric energy trough time period, and the stored energy can be supplied to the air conditioner in the electric energy crest time period and also supplied to the power grid reversely, so that the aims of reducing peak and filling trough are fulfilled, and other loads can be considered by taking the air conditioner as a center; due to a self-sufficient small-size power energy center, the air conditioner is not single electric equipment any more and can be used as an energy support to form a power generation, electricity utilization and power storage all-in-one air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an intelligent air conditioner with energy storage, a power supply system and a power supply method for the air conditioner. Background technique [0002] Power plants continuously generate electricity around the clock, and the power generation capacity of a power plant is usually fixed and not easily changed. This may cause insufficient power generation during peak periods of power consumption, and surplus power generation during low power consumption periods. If the generated electric energy is not used, it will cause a waste of power generation energy. During the peak period of electricity consumption, the electricity load is often reduced by means of power rationing measures. The disadvantage of power rationing measures is that it may affect the normal production and living needs of restricted users. [0003] Air conditioning is one of the electrical loads with the highest en...

[0002] Power plants continuously generate electricity around the clock, and the power generation capacity of a power plant is usually fixed and not easily changed, which may cause insufficient power generation during peak periods of power consumption, and surplus power generation during low power consumption periods

If the generated electric energy is not used, it will cause a waste of power generation energy

During the peak period of electricity consumption, the electricity load is often reduced through power restriction measures. The disadvantage of power restriction measures is that it may affect the normal production and living needs of restricted users.
