personal air-conditioning

This paper discuss about characteristics and energy performance of personal air-conditioning system for a general multi-bed patient’s room. Two types of personal air-conditioning systems are evaluated by the laboratory experiment. Energy performance of a peri-counter FCU (a conventional) air-conditioning system is simulated by CFD to compare with that of personal systems. Compared with the conventional system, personal air-conditioning system has an advantage from the viewpoint of amenity improvement, but may consume more energy for cooling in the system.

There are various demands for air-conditioning in each office space resulting from the variability of thermal distribution caused by a bias of heat sources. Furthermore, individual demands on the thermal environment are diverse. Therefore, it is difficult to satisfy all demands using conventional air-conditioning systems since these assume perfect mixing. Instead, demand may vary with the result that some spaces could be excessively or unnecessarily cooled. This paper examines an airflow and temperature control for personal air-conditioning.
