This article reviews the papers published in the Korean Journal of Air-Conditioning
and Refrigeration Engineering in 2020. The purpose of this article is to understand
the status of current research issues in the areas of heating, cooling, ventilation,
sanitation, and indoor environments of buildings and plant facilities. Summary of
this paper is follows.
(1) The topics of the paper in the field of building mechanical system were the energy
consumption, indoor environment analysis, building energy saving, ventilation system,
data center, renewable energy system and law of mechanical facilities.
(2) The topics of the research in the field of indoor environment were the IAQ, ventilation,
air cleaning, particulate matter, machine learning, UV, COVID-19, building energy
performance etc.
(3) In the field of the refrigeration system, the topics were refrigeration, dehumidification,
heat pump cycle, refrigerant, electric scroll compressor and absorption refrigerator
etc.
(4) The topics of the papers published in the field of heat and mass transfer were
the heat exchanger, heat storage and heat dissipation characteristics, heat exchanger,
the heat transfer of the liquid evaporator, the thermal conductivity of the vapor
chamber, hot air dryer and the thermoelectric element etc.
(5) Ventilation was the most cited keyword in the papers published in 2020, and the
next was the data center, energy recovery ventilator, geothermal system, absorbtion
chiller, building energy, heat transfer, PV, heat pump, heat exchange, dehumidification,
simulation, mass transfer, negative pressure isolation room etc. Also, COVID-19, UV
were suggested.
