Special Issue Information

Dear Colleagues,

Heating, Ventilation, and Air-Conditioning (HVAC) systems are crucial to achieve building energy efficiency and sustainability, human comfort, and welfare. The boom in the application of emerging technologies, such as machine learning, artificial intelligence, digital twins, etc., and the growing emphasis on natural cooling driven by the demand for concentrated and large-scale energy use, as represented by data centers, have resulted in increased amounts of research being conducted in this field. The exploration of cooling and heating source technology, terminal conditioning technology, etc., that promote the operation and maintenance practices of HVAC systems continues to deepen. All these factors have motivated numerous researchers to devote themselves to it.

This Special Issue aims to provide a platform for reporting the latest research progress in HVAC systems and evaluating the application of relevant theories and advanced technologies from a future perspective. Topics include, but are not limited to, the following:

  • HVAC system analysis;
  • Simulation and optimization of HVAC systems;
  • Advanced forecasting technologies for heating and cooling load and energy consumption;
  • Indoor thermal comfort and thermal adaptation;
  • IAQ (Indoor Air Quality);
  • Heat pump technology;
  • Dehumidification technology;
  • Data center cooling;
  • Evaporative cooling;
  • BIPVs (Building-Integrated Photovoltaics);
  • Low- or zero-carbon building energy systems;
  • Integrated energy systems for buildings;
  • Practices for energy efficiency of HVAC systems.

This research paper investigates a novel triangular honeycomb thermochemical energy storage reactor for low- and medium-temperature applications in buildings, emphasizing its potential to enhance sustainable heating. Using a validated 3D numerical model, the reactor’s performance is analyzed in depth across various configurations, focusing on key parameters such as energy storage density, pressure drop, internal air flow distribution, and round-trip efficiency. Results show that the reactor achieved an energy storage density of 872 kJ/kg and a round-trip thermal efficiency of 41.51% under optimal conditions. Additionally, the triangular honeycomb reactor (30°, 60, and 90°) configuration achieved the highest temperature lift of 48.7 °C. In a feasibility analysis for residential heating in northern China, the reactor with 30°, 60°, and 90° angles required 24.91% less volume to meet daily heating demands compared to other configurations. This study contributes valuable insights for the development of efficient, low-carbon heating solutions for low- and medium-temperature applications in buildings, offering interesting advancements in the field of thermochemical energy storage technology.

Under the background of “dual carbon” development goals, the rapid expansion of internet data centers driven by advancements in 5G technology has led to increased energy consumption and elevated heat densities within the server rooms in these facilities. In this study, the modular data center is taken as the research object for the purpose of figuring out a way to improve the thermal environment of the computer room, reduce power consumption, and ensure the safe and stable running of servers. To this end, this study established an airflow organization model for the modular data center and verified this model through experimental methods. Computational Fluid Dynamics (CFD) simulations were employed to investigate the effects of raised floor height, floor opening rate, and cold/hot air channel closure on airflow organization. Furthermore, the efficiency of airflow organization was evaluated using entransy loss metrics. The results show that optimal airflow conditions are achieved when the height of the raised floor is 600–800 mm, the opening rate is 40%, and the combined opening is 40%. Additionally, the closure of either the cold channel or both the cold and hot channels significantly improves airflow performance. Specifically, cold channel closure is recommended for new data centers with underfloor air supply systems, while combined cold and hot channel closure is suitable for data centers with high power density and extended air supply distances.
