Impact of the selection of electrical equipment on medical location facilities on safety and economics in Thailand

Hospitals represent remarkable structures that contribute to healing, support families and communities and enhance both quality of life and longevity. This investigation has two objectives: The initial objective is to gather data, assess the choice of electrical equipment and examine the energy consumption of hospitals. The second objective is to investigate methods for enhancing the safety of electrical equipment while also creating economic advantages from the 434 electrical transformers that provide energy to hospitals. The investigation utilizes data request form, statistical analysis methods (mean, standard deviation, percentage, T-test) and conducts three professional interviews. The results are presented below: 1) An in-depth assessment of energy consumption in healthcare facilities, focusing on the real operational percentages of electrical transformers, alternating current in circuit breakers and capacitor ratios. 2) Approaches for managing electricity consumption through the on-demand activation of transformers. 3) Suggestions for reducing costs and creating energy management systems focused on reaching carbon neutrality. The report further emphasizes concerns associated with overdesign in electrical systems. For example, decreasing the capacity of a transformer from 1600 kVA to 1000 kVA leads to a reduction in carbon emissions by 38.2%. Large systems contribute to heightened carbon emissions and significantly elevate operating and maintenance expenses. Furthermore, the dependence on human labor or machinery leads to increased carbon footprints. The results highlight the importance of improving hospital electrical system designs to strike a balance between efficiency, sustainability and economic value.
