Cold water host control method, device and equipment and storage medium

The invention relates to a cold water host control method, device and equipment and a storage medium, and relates to the technical field of air conditioners. The method comprises the steps that the load of a tail end air conditioner is obtained; when the load of the tail end air conditioner is smaller than the preset load, the cold water host is controlled to operate at the first load in the preset load interval, and the temperature of the target position is obtained; the target position is the position between the cold water host and the tail end air conditioner or the position between the cold water host and the cold storage tank; the minimum load of the preset load interval is greater than the preset load; when the temperature is lower than the first preset temperature, controlling the water chiller, the cooling water pump and the cooling tower to stop working; when the temperature is higher than the second preset temperature, controlling the water chiller, the cooling water pump and the cooling tower to s
