空调好坏的三项指标
1.制冷(热)量
空调器在进行制冷(热)运转单位时间内从密闭空间除去的热量,法定计量单位W(瓦)。 国家标准规定空调实际制冷量不应小于额定制冷量的95%。
2.能效比
又称性能系数,是指空调器制冷运转时,制冷量与制冷功率之比,单位W/W。国家标准规定,2500W空调的能效比标准值为2.65;2500W至4500W空调能效比标准值为2.70。
3.噪声
空调器运转时产生的杂音,主要由内部的蒸发机和外部的冷凝机产生。国家规定制冷量在2000W以下的空调室内机噪声不应大于45分贝,室外机不大于55分贝;2500W至4500W的分体空调室内机噪声不大于48分贝,室外机不大于58分贝。
