Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0026] Please refer to figure 1 As shown, it is a schematic diagram of the connection of the energy storage multi-connected air-conditioning unit of the present invention. The energy-storage multi-connected air-conditioning unit includes: an outdoor unit 20, an indoor unit 10, and several refrigerant pipelines connecting the outdoor unit 20 and the indoor unit 10 . In this embodiment, the indoor unit 10 may include several indoor units connected in parallel, and each indoor unit may also be connected with an electronic expansion valve (not shown) in series so as to control a single indoor unit. Of cou...

The invention discloses an energy-storage multi-connected air-conditioning unit, which comprises: an outdoor unit, an indoor unit, and several refrigerant pipelines connecting the outdoor unit and the indoor unit; the outdoor unit includes a gas-liquid separator, a compressor, a second A control valve, an outdoor heat exchanger, a second control valve, an energy storage device, a gas pipe shut-off valve and a liquid pipe shut-off valve, the input end of the compressor and the output end of the gas-liquid separator, the gas pipe shut-off valve , the indoor unit and the liquid pipe shut-off valve are connected through refrigerant pipes. The present invention proposes an energy-storage multi-connected air conditioner, which can realize the storage of cold energy when the power consumption is low or the load of the internal unit is low, and release the cold energy during the peak power consumption period or when the load is large, so as to achieve the purpose of rapid cooling and realize the cooling operation In addition, the present invention can also realize the accumulation of heat when the power consumption is low or the load of the indoor unit is low, which is used to provide heat for the defrosting of the outdoor unit, reducing the defrosting running time and increasing the overall heating capacity of the system.
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...
