Unit energy efficiency planning system

Abstract

The invention relates to a unit energy efficiency planning system. The system comprises a data acquisition module, a model selection scheme generation module, a control strategy determination module,a performance prediction module and a model selection scheme determination module. The data acquisition module acquires the unit operation related parameters, the model selection scheme generation module generates each model selection scheme according to the relevant parameters of unit operation, and the control strategy determination module predicts the energy consumption of each type selection scheme based on each control strategy, and determines a control strategy corresponding to each type selection scheme; the performance prediction module obtains the performance of each type selection scheme according to the control strategy corresponding to each type selection scheme, and the model selection scheme determination module determines a final model selection scheme and a corresponding control strategy of the unit system from all the model selection schemes according to the performance of all the model selection schemes. The unit energy efficiency planning system can predict the system operation energy consumption and the system performance, the model selection scheme and the control strategy are determined based on the prediction result, so that the final unit system and the corresponding control strategy are designed, and the problem of resource waste is effectively avoided.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a unit energy efficiency planning system. Background technique [0002] In the HVAC industry, the energy consumption of the air-conditioning machine room is an important concern. The industry has been discussing it in depth. The design institute's early system design / renovation has no basis for equipment selection and energy conservation. Due to the variety of system schemes, which not only involve the selection of primary pumps, secondary pumps, fixed-frequency conversion systems, and large and small machine systems, it is unrealistic to manually calculate the energy consumption in the cooling season. [0003] At present, designers often design based on past experience. After manual debugging at the project site according to the terminal load conditions, and after the system has been running stably for a long time, they can judge whether the energy-saving stra...

Problems solved by technology

[0004] If it is not enough to ensure that the energy consumption of the system is up to expectations, whether the equipment is at the optimal operating level, whether the energy-saving control strategy used by the system is optimal, and whether there is still room for optimization, resulting in waste of resources.
