What is air source heat pump defrosting control method and system based on 5G Internet of things technology?

An air source heat pump defrosting control method and system based on 5G Internet of things technology is applied to the background management terminal of the air source heat pump cluster, in which the air source heat pump cluster includes at least two air source heat pumps, the method comprises the following steps: (1) obtaining the status information of each air source heat pump in the air source heat pump cluster, wherein the status information of the air source heat pump includes the status collection information or the Working Status Information; The working state includes standby state, heating state, natural defrosting state and reverse circulation defrosting state S2 controls the working state transition of each air source heat pump according to the total inlet and outlet water temperature information of current air source heat pump cluster and the state information of air source heat pump. The intelligent control of the defrosting and the working state of the air source heat pump based on the background management terminal is helpful to improve the energy saving level of the defrosting control of the air source heat pump.
