Installation of a Central Monitoring System to Improve Climate Efficiency

The diploma thesis addresses the possibilities of improving the efficiency of a central air conditioning system through the use of a central monitoring system (CMS). The introduction presents the field of air conditioning in larger buildings and the challenges of energy efficiency, reliability and operational flexibility. The basic premise of the work is that a properly configured CMS enables measurable savings and better operational results. The research approach combines quantitative methods, such as measuring energy consumption and system responsiveness, and qualitative methods, such as case studies and analysis of challenges in CMS implementation.

Problem

The diploma thesis addresses the possibilities of improving the efficiency of a central air conditioning system through the use of a central monitoring system (CMS). The introduction presents the field of air conditioning in larger buildings and the challenges of energy efficiency, reliability and operational flexibility. The problem of inefficient operation of existing systems is defined, which often fail to exploit the potential of modern automation and data analytics.

The purpose of the work is to develop solutions for optimising the operation of central air conditioning through the integration of CMS, with the objectives of reducing energy consumption, improving comfort and increasing reliability.

Results

The basic premise of the work is that a properly configured CMS enables measurable savings and better operational results. The research approach combines quantitative methods, such as measuring energy consumption and system responsiveness, and qualitative methods, such as case studies and analysis of challenges in CMS implementation. The technical part of the diploma thesis describes in detail the operation of central air conditioning, thermodynamic processes, hydraulic distribution and regulation of terminal units.

Key components are presented, such as cooling devices, circulation pumps, fan-coil units, sensors and CMS, and their role in efficient energy transfer and regulation. Special attention is paid to the challenges of existing solutions, such as poor integration of devices, inadequate sensors, hydraulic imbalance and underutilisation of data. The work also addresses energy efficiency and classes, and highlights the limitations of standardised indicators and the need for a comprehensive system assessment.

The functionalities of CMS and its advantages in automation, personalisation of comfort, data analytics and benchmarking are presented. In the practical part, the impacts of CMS on the reliability of air conditioning equipment are analysed, using statistical and machine learning models and comparative analysis before and after CMS installation. The concluding chapter addresses the economics and sustainability aspects of CMS implementation, including cost analysis, environmental impact assessment of optimised air conditioning and equipment life cycle analysis.

The regulatory framework that influences the design and implementation of such systems is also presented. The conclusion confirms the hypotheses, highlights the practical implications of the results and provides suggestions for further research.
