Phase change material based on air-triggered cross-seasonal heat storage and application method thereof

The invention provides a phase change material based on air-triggered cross-seasonal heat storage and an application method thereof, and relates to the field of new energy storage materials. The phase change material based on air-triggered cross-seasonal heat storage comprises the following raw materials in parts by weight: 30-40 parts of deionized water, 15-20 parts of a coordination agent, 5-10 parts of a moisture medium substance, 3-8 parts of an additive and 3-5 parts of a chelating agent. The supercooling degree of the phase-change material is reduced through the added coordination agent, so that the phase-change material is closer to the equilibrium phase-change temperature, and the stability and the reliability of the phase-change material are improved; the change of the phase change temperature along with time or environmental conditions can be reduced due to the over-low degree of supercooling, so that the phase change temperature drift of the phase change material is reduced, and the phase change ma
