Control system used for achieving operation energy conservation of central air conditioner refrigeration station and control method

Abstract

The invention discloses a control system used for achieving operation energy conservation of a central air conditioner refrigeration station and a control method. The control system comprises a data collection unit, a strategy optimization interface unit, a cloud data storage unit, a cloud optimization analysis unit and a result feedback unit. The control method comprises the steps that a refrigeration station system is divided into a plurality of independent subunits; the energy efficiency index and the influence independent variable of each independent subunit are determined; the index and the independent variable of each independent subunit are obtained and recorded; and the relation between the index and the independent variable of each independent subunit is analyzed. Through the control system used for achieving operation energy conservation of the central air conditioner refrigeration station and the control method, the reliability and the usefulness of the automatic control system in actual projects are improved, and thus the risk of being wasted is lowered; and long-time energy conservation optimization of the refrigeration station is achieved, and the debugging process is simplified.

Description

technical field [0001] The invention relates to the field of central air-conditioning, in particular to an energy-saving control system and control method for realizing the operation of a central air-conditioning refrigeration station. Background technique [0002] Central air-conditioning accounts for a very large proportion of energy consumption in public buildings, and refrigeration stations account for nearly 70% of the energy consumption of central air-conditioning. Realizing energy-saving operation of refrigeration stations is of great significance to the energy saving and consumption reduction of public buildings. At present, the control system of the central air-conditioning refrigeration station has the following problems: First, the control system of the refrigeration station is often debugged once in the early stage of operation, and the preset is completed, and the automatic control operation is carried out according to this setting throughout the life, which cann...

Problems solved by technology

At present, the control system of the central air-conditioning refrigeration station has the following problems: First, the control system of the refrigeration station is often debugged once in the early stage of operation, and the preset is completed, and the automatic control operation is carried out according to this setting throughout the life, which cannot adapt to the actual situation of the project. Changes in demand caused many projects to abandon automatic control and use manual instead after running for a period of time; second, the existing refrigeration station control system debugging method (that is, to use short-term system operation data feedback and adjust the preset "parameters" to To achieve the purpose of debugging), on the one hand, the experience and level of the debugging personnel are high, on the other hand, the short-term data feedback is often relatively one-sided, which not only makes debugging difficult, but also fails to achieve the purpose of energy-saving operation.
