Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your recent works to an upcoming Special Issue, titled “Advanced Heating and Cooling Technologies for Sustainable Buildings”. As the global demand for energy-efficient and environmentally friendly building application systems grows, innovative heating and cooling solutions can play a pivotal role towards the achieving sustainability goals. The enhanced penetration of renewable energy sources in buildings offers a promising pathway for decarbonizing the sector while enhancing energy efficiency. However, despite technological advancements, the widespread adoption of renewable-based heating and cooling systems faces economic and technical barriers, including high upfront costs and system integration challenges. Therefore, rigorous techno-economic assessments are essential to evaluate their feasibility and competitiveness. Simultaneously, with increasing concerns over the environmental footprint of energy systems, life cycle assessment (LCA) emerges as a crucial tool for objectively analyzing the environmental impact of advanced heating and cooling solutions. This Special Issue seeks high-quality research on cutting-edge developments, performance evaluation, economic feasibility, and environmental assessments of emerging technologies, aiming to drive innovation and policy recommendations in the field. Topics of interest for publication include, but are not limited to, the following:

  1. Renewable driven heating and/or cooling systems;
  2. Hybrid cooling and/or heating systems
  3. Techno-economic optimization;
  4. Life cycle analysis;
  5. Environmental evaluation;
  6. Advanced configurations;
  7. Experimental activities on heating/cooling systems for building applications;
  8. Solar cooling/heating.

A new evaporative condensation refrigerant pump heat pipe air-conditioning unit based on a microchannel heat pipe heat exchanger is proposed. Performance experiments were conducted on the unit, and the experimental results show that the cooling capacity of the unit in the dry, wet, and mixed modes can reach 112.1, 105.8, and 115.4 kW, respectively, the optimal airflow ratio of the secondary/primary airflow is 2.2, 1.8, and 1.8, respectively, and the EER decreases with increasing airflow ratio. With increasing dry- and wet-bulb temperatures of the secondary-side inlet air, the cooling capacity and energy efficiency ratio of the unit decrease, and the energy efficiency ratio in the wet mode is higher than that in the dry mode, which can prolong the operating hours of the wet mode within the operating temperature range of the dry mode and improve the energy efficiency of the unit. A new calculation method for the refrigerant charge is proposed, and the optimal refrigerant charge is 32 kg based on the experimental results, which agrees with the theoretical calculation results.
