Abstract

The invention relates to an air source heat pump and water pump linkage control method and system and electronic equipment. The method comprises the steps: detecting the temperature difference of supply water and return water of all air source heat pumps which are started to operate, and for any air source heat pump, if the temperature difference of the supply water and the return water is within a preset temperature change range, keeping the current running states of the air source heat pump and the matched water pump; otherwise, adjusting the operation frequency of the water pump matched with the air source heat pump according to a preset rule till the temperature difference between the supply water and the return water is within the preset temperature change range, and therefore linkage control over the air source heat pump and the water pump is achieved. According to the technical scheme, due to the fact that the operation frequency of the matched water pump is intelligently adjusted according to the temperature difference of the supply water and the return water of the air source heat pump, system energy consumption can be effectively reduced, system operation cost is reduced, and the heating energy efficiency ratio of the system is increased.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an air source heat pump and water pump linkage control method, system and electronic equipment. Background technique [0002] At present, air source heat pumps are widely used in breeding places. Due to extensive management, the linkage control of air source heat pumps and water pumps is currently controlled by simple switches, that is, the host of air source heat pumps is turned on, and all water pumps are turned on. [0003] In the control method of the air source heat pump and the water pump in the prior art, as the load increases or decreases during operation, the load is only adjusted by the air source heat pump main unit. The air source heat pump is in a state of large flow and small temperature difference for a long time, and the water pump can High consumption is not conducive to energy saving and environmental protection.
