In the invention, the increase of energy consumption, caused by a power grid pollution source, can be effectively reduced; the efficiency of an air conditioning system can be increased; the service life of air conditioning equipment is prolonged; moreover, the electricity saving device has multiple functions of electricity saving and protection.

Description

technical field [0001] The invention relates to a power-saving technology for logistics warehouse electrical appliances, in particular to a logistics warehouse air-conditioning power-saving device. Background technique [0002] The air-conditioning equipment used in logistics warehouses is mainly based on central air-conditioning. In the central air-conditioning system, the capacity of chilled water pumps and cooling water pumps is selected according to the maximum design heat load, and a margin of about 10% is left. In the long-term During the work, the water pump system works at a fixed maximum water flow rate, and the water pump system works under the condition of low temperature difference and high flow rate for a long time, which increases the energy loss of the pipeline system and wastes the delivery energy of the pump operation.
