| 摘要: |
| 房间空调器目前同时用两种完全不同的能效指标EER、COP指标以及APF指标来标称空调器能效。为了便于比较不同能效指标标称的空调器性能，需要将传统的EER和COP能效指标转化成APF能效指标。本文给出了一种利用GB7725—1996中EER和COP等性能参数直接计算APF的方法。该方法首先将APF转化为关于“额定制冷量”、“额定制冷功率”、“额定制热量”和“额定制热功率”的函数，然后联立EER、COP和APF的计算式消除中间变量。根据本文开发的公式，房间空调器的APF可以通过制冷和制热的额定能力和能效进行简单四则运算便可得到。 |

| Abstract: |
| Two different energy efficiency indices EER, COP and APF are both used to evaluate the energy efficiency of room air conditioners, nowadays. In order to compare which air conditioners are more energy-saving, the traditional energy efficiency index EER and COP need to be transformed to APF. This paper presents a method to evaluate APF for room air conditioner by using EER and COP. In the method, APF is transformed to equations referenced to the same intermediate variables including cooling capacity and power consumption under standard condition at first, and then combing the equations of EER and APF to eliminate the intermediate variables. The equation has the capability to calculate APF of room air conditioners with on/off compressor by the energy efficiencies of cooling and heating modes. |
