Problems solved by technology

For the huge temperature difference in four seasons, the traditional centralized control cannot change the power of the water pump, resulting in the use of a water pump with a higher power than the first power when the cooling load is low, resulting in waste of electric energy
If frequency converter is used, it will add high cost

Abstract

The invention relates to the technical field of heat pump air conditioners, and particularly discloses a water pump switching control method and device, computer equipment and a storage medium. The water pump switching control method comprises the steps that a water pump unit is started, water pumps comprise a first-power water pump and a second-power water pump, and the power of the first-power water pump is larger than that of the second-power water pump; the heat pump operation number of the heat pump unit in current operation is obtained; when the operation number of the heat pumps is larger than or equal to a first preset threshold value, only the first-power water pump is started; and when the operation number of the heat pumps is smaller than or equal to a second preset threshold value, only the second-power water pump is started. The water pumps are switched by comparing the operation number of the heat pumps of the heat pump unit with the first preset threshold value and the second preset threshold value, pipeline damage caused by too large water pressure and water output by the water pumps can be avoided, energy conservation and emission reduction can be achieved, a frequency converter is not used, the water pumps with the power needed by the heat pump unit at different temperature differences can be automatically adapted, and the energy conservation and emission reduction are achieved. Electric energy is saved.

Description

technical field [0001] The present application relates to the technical field of heat pump air conditioners, and in particular to a water pump switching control method, device, computer equipment and storage medium. Background technique [0002] The heat pump central air-conditioning system is generally realized through the air-fluorine-water-air heat exchange method, in which the waterway is an important cold and heat transfer medium. As the control core of the central air-conditioning system, the heat pump centralized control system (hereinafter referred to as centralized control) not only needs to be able to control the heat pump air-conditioning unit, but also needs to be able to control the main water pump of the project to drive the water circulation to create conditions for the transfer of cold and heat. The traditional centralized control is generally linked with the machine. By obtaining whether the machine needs to turn on the water pump, when it detects that any m...
