Abstract

The embodiment of the invention discloses an energy-saving control method and system for a chilled water pump group. The energy-saving control method for the chilled water pump group comprises the steps that the most unfavorable tail-end pressure difference between a manifold and a water collector of a chilled water circulating system is calculated; the pressure difference between the two sides of a water supply and return pipeline communicated with the chilled water pump group is adjusted to the most unfavorable tail-end pressure difference by adjusting the work rotation speed of the chilled water pump group; and the pressure difference between the two sides of the water supply and return pipeline is kept equal to the most unfavorable tail-end pressure difference, and the work rotation speed of the chilled water pump group and the number of working chilled water pumps are adjusted according to energy-saving parameter control strategy of the chilled water pump group, so that the energy conservation of the chilled water pump group is reduced to the minimum, wherein energy-saving parameters comprise the working rotation speed, the number of working chilled water pumps, the power and the efficiency of the chilled water pump group. Through the adoption of the technical scheme, the work rotation speed of the chilled water pump group and the number of working chilled water pumps can be controlled comprehensively, the output efficiency of the chilled water pump group is improved, the output power of the chilled water pump group is lowered, and therefore the output power consumption of the chilled water pump group is lowered.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, in particular to an energy-saving control method and system for a chilled water pump set. Background technique [0002] HVAC refers to the related equipment responsible for heating, ventilation and air conditioning in the room or in the car. Its water circulation system is mainly composed of chilled water circulation system and cooling water circulation system. It is composed of air conditioner, terminal equipment of air conditioner, water collector and circulation pipeline connecting the above devices. [0003] The energy consumption of HVAC is mainly generated by the above-mentioned chilled water circulation system and cooling water circulation system. Among them, the energy consumption consumed by chillers and chilled water pumps in the chilled water circulation system accounts for a considerable proportion. The method is generally to install an electric valv...
