This article provides a comprehensive overview of the latest research findings in heating, cooling, ventilation, sanitation, and indoor environments of buildings and plants. It reviews articles published in the Korean Journal of Air-Conditioning and Refrigeration Engineering throughout 2025. Below is a summarized outline of the reviewed papers.
(1) In the field of building mechanical systems, 17 papers were published in 2025, a slight decrease from 21 papers in 2024. The research topics increasingly focused on high-efficiency energy systems aimed at carbon neutrality and AI-based prediction and control technologies.
(2) In the building environment field, 23 papers were published in 2025, reflecting a slight increase from 21 papers in 2024. Research topics evolved to emphasize intelligent building studies that integrate energy management, indoor air quality, and safety, with a strong focus on AI and data-driven analyses as well as digital transformation.
(3) In the refrigeration field, 10 papers were published in 2025, marking a slight increase compared to the previous three years. While refrigeration systems and heat pumps remained core areas of cycle-based research, there was a noticeable rise in studies related to HVAC, dehumidification, and ventilation, indicating a diversification of research topics that extend beyond traditional cycle-focused studies to include integrated applications like air-conditioning systems.
(4) In the heat transfer and thermofluid field, 10 papers were published in 2025, consistent with the volume in 2024. The classification shifted from “general thermofluids and phase change” to “general thermofluids and heat exchangers.” Key topics included heat exchangers, profitability assessments of hydrogen production systems, combustion characteristics of industrial boilers, baffle optimization in gas reactors, and the development of heat transfer correlations for R1336mzz using deep learning. |

This study introduces a physics-based co-simulation framework designed to evaluate the differential-pressure control performance of HVAC systems in nuclear fuel cycle facilities. These facilities handle radioactive materials under stringent confinement requirements, making it crucial to maintain negative pressure gradients between different zones for safety. Since experimental testing under degraded or abnormal conditions is not feasible, a simulation-based verification approach was adopted. In this framework, the building envelope and ventilation zoning were modeled using EnergyPlus, while major HVAC components?such as fans, dampers, filters, and ducts?were represented with the Modelica Buildings Library, relying on physics-based formulations. The two domains were integrated through a functional mock-up interface (FMI), facilitating comprehensive analysis of thermal loads and dynamic airflow responses. The Modelica fan model demonstrated strong correlation with theoretical affinity laws, achieving an R² value above 0.99 for airflow, static pressure, and power consumption. The coupled Modelica-EnergyPlus simulation successfully reproduced the intended pressure cascade, with calculated pressure differences in the hot-cell zones (-334 to -149 Pa) satisfying the design criteria. These findings indicate that the proposed framework offers a reliable and safe method to assess HVAC performance in safety-critical nuclear facilities and lays the groundwork for future research on fault prediction, degradation assessment, and control optimization. |
