| 1. | Examination and analysis of seasonal energy efficiency ratio of room air conditioner with two compressors
双压缩机房间空调器季节性能试验及分析评价 |
| 2. | When buying an air - conditioner , check its energy efficiency ratio , with lower numbers denoting better efficiency
购买冷气机时，应留意其能量效率比, ，数值愈低代表效能愈佳。 |
| 3. | Not only including the heat transfer of envelop , it is also considered air infiltration inner heat gain lighting energy efficiency ratio for energy consume calculation
建筑能耗计算不仅考虑围护结构的传热，而且要包括空气渗透传热、内部得热、室内照明、空调采暖设备的能效比等因素。 |
| 4. | This paper also shows the energy efficiency ratio of the whole gchp and gives some suggestions for modifying and optimizing the method of design and construction . in the end , the author establishes a heat transfer model for ground heat exchanger of u - shaped gchp
最后，我们在综合利用最新的实验和理论成果的基础上，建立了u型垂直土壤源热泵系统地下换热器的传热模型，并使用有限差分法给出了数值解法。 |
| 5. | Base ehtv solved the problem that in the case of different layout demand building landform indoor condition all buildings has the same building design control value for one region . it is also cleared that the key for building energy design is improving the building envelops insulation of and the energy efficiency ratio of equipments
基准ehtv指标则创新地解决了受规划要求、地形、使用条件等限制的各种体形建筑节能控制指标为相同带来的矛盾，明确建筑节能设计的关键是提高围护结构的保温隔热水平及设备能效比。 |
| 6. | First ehtv extended the region of ottv , it is the same with all weather condition , but ottv is used in hot zoon for air - condition . ehtv could calculate energy consume , but ottv is just a heat transfer value for not including air infiltration inner heat gain lighting energy efficiency ratio of equipments
首先是扩大了指标的适用范围， ottv主要是针对炎热地区的空调节能指标， ehtv指标能适用于各种气象条件，此外ehtv的能耗计算方法，解决了ottv指标不包括空气渗透、采光、空调采暖设备等因素，不能直观反映建筑能耗的不足。 |
