Abstract

The invention discloses an energy storage multi-connected air conditioning unit. The energy storage multi-connected air conditioning unit comprises an outdoor unit, an indoor unit and a plurality of refrigerant pipelines for communicating the outdoor unit with the indoor unit, wherein the outdoor unit comprises a gas-liquid separator, a compressor, a first control valve, an outdoor heat exchanger, a second control valve, an energy storage device, a gas pipe stop valve and a liquid pipe stop valve; the input end of the compressor is respectively connected with the output end of the gas-liquid separator, the gas pipe stop valve, the indoor unit and the liquid pipe stop valve through the refrigerant pipelines. According to the energy storage multi-connected air conditioning unit provided by the invention, the refrigerating capacity can be stored in an electricity valley period or in a low inner machine load period and can be released in an electricity peak period or in a high inner machine load period, so that the purpose of quick refrigeration is reached, and the economical efficiency of refrigeration operation is realized; moreover, heat can also be stored in the electricity valley period or in the low inner machine load period, and the energy storage multi-connected air conditioning unit is used for providing heat for defrosting the outdoor unit, so that the defrosting operation time is shortened, and the whole heating capacity of the system is improved.

Description

technical field

[0001] The invention relates to an air-conditioning heat pump system, in particular to an energy-storage multi-connected air-conditioning unit capable of heat storage and cold storage and a control method thereof. Background technique

[0002] Multi-split refers to a system consisting of one or more outdoor units and multiple indoor units installed in different application spaces. The multi-line system is widely used in commercial and office places due to its advantages of saving installation space, energy saving and environmental protection, and easy control and management.

[0003] In recent years, with the development of the economy, the contradiction between supply and demand of domestic energy has become increasingly tense, especially during the peak period of electric energy use, the phenomenon of insufficient electric energy supply often occurs in various places. In order to cope with this phenomenon, many places have implemented different electricity...
