As the only international journal in the field of air-conditioning and refrigeration in Asia, IJACR is dedicated to providing a platform for sharing and disseminating latest research results and information to societies related with air-conditioning and refrigeration. We invite original research papers or comprehensive review articles addressing various aspects of air-conditioning and refrigeration, which includes broad range of applications and underlying theories including fluid dynamics, thermodynamics, heat transfer, and nano/bio-related technologies. Future energy technologies, such as fuel cell, wind turbine, solar cell/heat, geothermal energy are also considered in the journal.
