High-efficient energy-storage central air-conditioning system

Abstract

The invention discloses a high-efficient energy-storage central air-conditioning system, in particular to a high-efficient energy-storage central air-conditioning system which adopts a plurality of water-temperature naturally-layered small and medium flat-bottom cylindrical impounding tanks, wherein the plurality of water-temperature naturally-layered small and medium flat-bottom cylindrical impounding tanks are connected in series and in parallel, and water distributors are arranged in the impounding tanks, so that the water layering effect is good; and the impounding tanks are adopted to store cold water or hot water at large temperature difference at night, constant temperature cooling or heating can be carried out in the day time. The central air-conditioning system is easy, flexible and reliable to use, high in efficiency, small in investment, maximally realizes the peak load shifting of a power grid, optimizes a power utilization structure, saves operating cost, saves primary investment and the like; and thermal insulating layers are arranged around energy storage tank groups, so as to insulate the impounding tanks, so that the energy storage of the impounding tanks is more high efficient.

Description

technical field [0001] The invention relates to a high-efficiency energy storage central air-conditioning system. Background technique [0002] With the continuous development of the national economy, the demand for energy is increasing, and the contradiction between economic development and energy is getting worse day by day. As one of the basic industries of the national economy, the power energy industry has made great progress with the development of the economy, but the contradiction between power supply and demand is still increasing day by day. The air-conditioning power load accounts for a large proportion of the peak load of the urban power grid. In some big cities, the air-conditioning power load even accounts for 40% of the city's total power load, which directly increases the power grid's peak power shortage. However, due to power consumption in the second half of the night, it cannot reach The minimum load of the power grid has caused a huge waste of low-peak e...

Problems solved by technology

[0004] At present, there are water storage air conditioning systems on the market that use the fire water pool as the cold storage equipment, but due to the limitations of the fire water pool itself, the cold storage system must be built on the fire water pool, otherwise a cold storage pool needs to be built, the construction period is long, and the site construction has a great impact, etc. , and, when the system needs to store heat at the same time, it cannot use the fire water pool to store heat, etc.
