通过对定速与转速可控房间空调器能效标准的分析,发现两类房间空调器的能效划分标准、划分等级以及制冷运行室外温度发生时间均有不同的规定。因此对国内市场上的定速房间空调器制冷量和制冷循环的能效比(EER)、转速可控房间空调器制冷量和制冷季节能效比(SEER)、以及定速房间空调器与转速可控房间空调器的能效等级现状等方面进行了调研统计。利用热力学完善度对两类房间空调器能效等级进行计算,发现2008版转速可控房间空气调节器的能效等级的热力学完善度偏低,根据热力学完善度相一致的原则,提出转速可控房间空调器新的能效标准等级的建议。
Through the analysis of energy efficiency standards for air conditioners with constant speed and speed control, it is found that there are different requirements for energy efficiency division, classification level and outdoor temperature of cooling operation in two types of room air conditioners. Therefore, the domestic market, fixed-speed room air conditioner cooling capacity and refrigeration cycle energy efficiency (EER), the speed controllable room air conditioner cooling capacity and cooling season energy efficiency (SEER), as well as fixed-speed room air conditioners and speed controllable Room air conditioner energy efficiency status and other aspects of the survey statistics. Based on the calculation of the energy efficiency levels of two types of room air conditioners using the thermodynamic improvement degree, it is found that the degree of thermodynamic improvement of the energy efficiency rating of the room air conditioners with 2008 speed control is low. Based on the principle that the degree of thermodynamic improvement is consistent, a speed controllable room air conditioner New recommendations for energy efficiency standards.
