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.
