RESEARCH ON THE ADVANCED USE OF MULTI-SPLIT TYPE AIR-CONDITIONING SYSTEM


An energy performance of a multi-split type air-conditioning system was evaluated
based on BEMS data and an investigation under actual operation. A simulation model
developed in other research was verified. In accuracy evaluation of model based on BEMS
data, it was confirmed that output values of the model are highly similar to BEMS data. In
addition, it was confirmed that outdoor DB temperature is connected to a compression work
because a heat exchange increases due to decrease in outdoor DB temperature. The indoor
thermal environment in summertime of Building A under the multi-split type air-conditioning
system that uses developed models was investigated. By a continuous measurement and
punctual measurement, it was confirmed that the air temperature in task zone didn’t fluctuate
rapidly, and an air draft didn’t influence comfort in task zone.
