摘要
随着变频空调季节能效在全球大范围地区的实施,对变频空调的能效要求越来越高,其中蒸发器的设计对空调性能影响很大,蒸发器的流路研究成为了提高性能的关键因素。通过对日本APF评价方法及能效计算公式研究,中间点能效在日本APF计算中占比高达80%;通过HXSim Copper Alliance换热仿真软件模拟仿真两种蒸发器流路的制冷能力以及在出口日本2.8 kW热泵分体空调上进行试验验证,对比分析发现蒸发器少进多出流路对中间点能效提升很大,从而在很大程度上可以提升APF。
With the implementation of seasonal energy efficiency of variable frequency air conditioning in a large area of the world, the energy efficiency requirements of variable frequency air conditioning are becoming higher and higher, among which the design of evaporator has a great infiuence on the performance of air conditioning, and the fiow path research of evaporator has become a key factor to improve the performance. By studying the evaluation method and energy efficiency calculation formula of APF in Japan, the energy efficiency of intermediate point accounts for 80% of the calculation of APF in Japan. HXSim Copper Alliance heat exchange simulation software was used to simulate the refrigeration capacity of the two evaporator fiow paths, and the experimental verification was carried out on the split air conditioner of 2.8 kW heat pump exported from Japan. The comparative analysis found that the energy efficiency of the intermediate point was greatly improved by the fewer inlet and more outlet fiow paths of the evaporator, thus the APF could be improved to a large extent.
