Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0043] Considering that in the cold source system, the energy efficiency of the system is equal to the cooling capacity of the chiller divided by the sum of the input power of the chiller, the input power of the chilled water pump, the input power of the cooling water pump, and the input power of the cooling fan. Under normal circumstances, the size of the terminal load determines the cooling output of the unit, which is less affected by human influence, but the number and frequency of fans and water pumps can generally be manually intervened. Under the premise of the normal operation of the un...

Abstract

The invention provides an energy efficiency control method and device. The energy efficiency control method comprises the steps: the objective function of energy consumption parts is built; the constraint conditions of the energy consumption parts in the operating process are obtained; through the constraint conditions, the optimal solution of the objective function is obtained, wherein the optimal solution represents the parameter combination of the energy consumption parts when the minimum value of the objective function is taken; and according to the optimal solution, the energy consumptionparts are controlled. Through the energy efficiency control method and device, the technical problems that energy consumption is too large, and resources are wasted are solved, and the technical effects that the energy efficiency is improved, and resource waste is reduced are achieved.

Description

technical field [0001] The present invention relates to the technical field of equipment control, in particular to an energy efficiency control method and device. Background technique [0002] At present, frequency conversion technology is widely used because of its advantages of smooth start-up without impact, convenient and accurate adjustment, and energy-saving operation. In some cold source or cold station systems, frequency converters can also be used to control the speed of water pumps and fans to adjust the water and air volume. [0003] Although frequency converters are used in some cold source systems to adjust the water volume and air volume, in the actual control process, it is often automatically adjusted based on the temperature change of the incoming and outgoing water. Although frequency converters are used in some occasions, they are generally controlled manually, and fans or water pumps generally operate at a certain constant frequency / speed. That is, in t...
