The result shows that the cooling capacity increases with increasing generator heat transfer. The coefficient of performance of the system increases when the quantity of the generator heat transfer is increased from 6 kW to 7 kW, however it decreases in the range of 7 kW-9 kW. When the fan frequency increases, the temperature of liquid ammonia leaving condenser decreases, while the cooling capacity and the COP of the system increases. When the flow rate and inlet temperature of water/glycol increases, the evaporator takes more heat away and the cooling capacity and COP of the system increases.

其结果可发现当发生器加热量增加，系统温度增加系统冷冻能力增加，但其COP於6 kW-7 kW 系统COP会有先增加，於7 kW-9 kW，系统COP会有下掉的趋势；在冷凝器方面，当风扇频率增加，冷凝器温度降低时，冷凝器出口冷媒随之降低，系统冷冻能力会有所提高，COP亦增加；在蒸发器方面，蒸发器卤水出口温度及卤水流量增加，可以使蒸发器带走更多的热量其系统冷冻能力及COP也就会相对增加。

It can be concluded from the above experiment results that for the auxiliaryheated arc plasma generator, an area which has uniform temperature distribution andhigher temperature.
