GB 50189-2015 第2.0.9条
| | **Energy Efficiency Ratio (EER)**: The ratio of the cooling capacity (or heating capacity) provided by air-conditioning equipment to its input power under rated operating conditions. In hotel buildings, the energy efficiency ratios of unitary air conditioners, VRF systems and other equipment must meet the limit values specified in the standards (e.g., when the nominal cooling capacity is ≤14 kW, EER ≥3.0). |
