It also introduces the commercial split air conditioner to the market. VRF (variable refrigerant flow) system is kind of major commercial split air conditioners. Basically, the performance and efficiency of VRF would be influenced by outside air temperature. This study is to analysis the effect of the misting system on reducing the supply air temperature and energy saving consequence. We are attempted to spend the lowest cost but meet the achievement of best energy saving performance.
The result shows that the misting system can reduce supply air temperature by 1.5℃ maximum. As per VRF type 250, it also reduces the supply air temperature of condenser by 3.8℃ maximum and averaged by 1.23℃. When evaluating to type 800, it may reduce 4.5℃ maximum with the average of 1.21℃. Compared type 250 to type 800 in the aspect of energy saving, maximum saving ratios are 5.29% and 12.33% respectively; total averaged saving ratios are 1.15% and 3.97% respectively.
