Problems solved by technology

[0004] (2) There is a risk of thermal runaway in lithium batteries
However, judging from the current public reports of fire and combustion accidents in lithium battery energy storage systems, no matter whether the application scenario of lithium batteries is electric vehicles or energy storage power stations, once a fire occurs, it will generate rapid combustion and a large amount of heat leading to a chain reaction, while gas fire extinguishing is difficult. Cool down the fire battery in a short period of time. Since the battery is still reacting violently and flammable gas is constantly escaping, the possibility of re-ignition is very high.

Abstract

The invention provides an air conditioner fire fighting system. The air conditioner fire fighting system comprises air conditioner equipment and fire fighting equipment. The air conditioning equipment is used for adjusting the environment temperature of a service space. The fire-fighting equipment comprises a fire-fighting water pipeline, wherein the fire-fighting water pipeline is connected to the air conditioning equipment so as to lead out fire-fighting water of the fire-fighting equipment from the air conditioning equipment.

Description

technical field [0001] The invention relates to fire-fighting technology, in particular to an air-conditioning and fire-fighting combined system. Background technique [0002] Lithium-ion batteries have the advantages of high operating voltage, high energy density, high specific capacity, long cycle life, and fast response, so lithium batteries are beginning to be widely used in the field of energy storage. During the storage of lithium batteries, there are the following hidden dangers that affect the performance of lithium batteries and the safety of energy storage power stations: [0003] (1) The output performance of lithium batteries will drop significantly at low temperatures. Especially for lithium batteries using lithium iron phosphate, due to the low conductivity of lithium iron phosphate, poor diffusion of lithium ions, and poor conductivity at low temperatures, the internal resistance of lithium batteries increases and battery charging and discharging are hindered...
