Energy-saving air conditioner capable of storing electricity

Abstract

The invention discloses an energy-saving air conditioner capable of storing electricity. The energy-saving air conditioner comprises an air conditioner body, wherein the air conditioner body is connected with a circuit module; the circuit module comprises a mains supply circuit, an alternating current power supply circuit and an electricity storage circuit; the mains supply circuit is used for connecting a mains supply power grid with the air conditioner body; the two ends of the alternating current power supply circuit are connected with the mains supply power grid and the air conditioner body respectively; the electricity storage circuit is connected in parallel with the mains supply circuit, is connected with the air conditioner body, is used for storing electric energy, and comprises acharging circuit, a second switching circuit, a storage battery and a first switching circuit which are arranged in sequence along the direction from the mains supply circuit to the air conditioner body. The electricity storage circuit is connected in parallel with the mains supply circuit, and is controlled by the first switching circuit and the second switching circuit to realize electricity storage or discharge, and the storage battery is charged at valley time, so that the storage battery discharges the air conditioner body under the condition of power failure or at peak time, and off-peak electricity utilization is realized; the storage battery is used at peak time, so that load peaks are effectively avoided, the electricity price is lowered, and the cost is saved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an energy-saving air conditioner capable of storing electricity. Background technique [0002] In recent years, due to the increase in national income, the air-conditioning load has increased significantly, resulting in a sharp increase in the peak load of the power system. Therefore, how to promote energy storage air-conditioning systems to general large-scale commercial office buildings and industrial circles is the most direct and effective load management method at this stage. Although there are a few buildings in China that use ice storage systems or ice water storage systems, the heat preservation of ice storage systems is difficult, which will inevitably cause certain losses. Long-term use will waste some energy and cannot achieve energy-saving effects. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems ex...
