Our test apparatus was able to test multi-split system air-conditioners and the packaged type air-conditioners with varying thermal load conditions.
Using our test apparatus, tests of the multi-split system and the packaged type electric air-conditioners (both types of thermal storage and non-storage), gas engine air-conditioners were performed.
It was made clear that the electric air-conditioners were superior to the gas engine air-conditioners in the performance characteristics. As a result, the cooling and heating capacity ratio of the measured values to the specific values was over 95% for the electric air-conditioners and about 80% for the gas engine air-conditioners. The primary energy efficiency was 0.7-1.2 for the electric air-conditioners and 0.6-0.8 for the gas engine air-conditioners.
