Air source heat pump defrosting regulation and control method and system based on 5G Internet of Things technology

Abstract

The invention provides an air source heat pump defrosting regulation and control method and system based on the 5G Internet of Things technology. The method is applied to a background management end of an air source heat pump cluster, wherein the air source heat pump cluster comprises at least two air source heat pumps, and each air source heat pump is in communication connection with the background management end. The method comprises the following steps that S1, the state information of each air source heat pump in the air source heat pump cluster is acquired, wherein the state information of the air source heat pumps comprises state acquisition information or working state information; the working state comprises a standby state, a heating state, a natural defrosting state and a reverse circulation defrosting state; and S2, working state conversion of the air source heat pumps is controlled according to the total inlet and outlet water temperature information of the current air source heat pump cluster and the state information of the air source heat pumps. Defrosting and working states of the air source heat pumps are intelligently controlled on the basis of the background management end, and the energy-saving level of defrosting control of the air source heat pumps can be improved.

Description

technical field [0001] The invention relates to the technical field of new energy and energy saving, in particular to an air source heat pump defrosting control method and system based on 5G Internet of Things technology. Background technique [0002] An air source heat pump is a device that is driven by a motor and uses a vapor compression refrigeration cycle to transfer the heat in the low-grade heat source air to a high-grade heat source such as water or air. When the ambient temperature is low and the humidity is high, frosting will occur during the heating process of the air source heat pump, which will affect the heating efficiency. At this point, the air source heat pump needs to be defrosted. The existing air source heat pump judges the frosting situation and controls the defrosting by itself. For the judgment of frosting conditions, the existing air source heat pumps mostly judge the frosting conditions according to the ambient temperature and fin temperature, or ...
