| 1. | Ahu coil design shall be based on 6 . 7 degrees centigrade chilled water supply temperature 空气调节装置卷设计应该在6 . 7摄氏度冷却水供应温度的基础上。 |
| 2. | For this reason , we propose a control of the supply temperature by the average temperature of the last 24 hours 因此,我们建议,用头一天24小时的平均温度作为控制温度。 |
| 3. | Hot water supply temperatures , hot water storage , hot water supply systems , hot water equipment , water heaters , pipes , etc 热水供应温度、热水储存、热水供应系统、热水设施、热水器、热水管等 |
| 4. | We can figure out the initial value of the watcr supplied tcmperature in the second - net according to the water supplied temperature in the first - net 根据一次热网供水温度计算出二次供水温度的设定值。 |
| 5. | Since the supply temperatures for heating and for cooling are kept moderate due to the low power densities needed , it makes sense to use a heat pump for heating as well as for cooling 因为所需要的功率低,输送的采暖和制冷温度保持适度,才有可能使用热泵采暖和制冷。 |
| 6. | Control principle : for the high inertia for changing of the supply temperature and for the auto - controlled behaviour within certain limits , a usual control strategy does not make sense 控制原理:对输送温度的较大惯性和一定范围内的自我调控特性,通常的控制方法满足不了这种要求。 |
| 7. | Water supply temperature , indoor design temperature , distance of embedded pipe , diameter of embedded pipe and material of ground floor are important factors influencing cooling and heating radiation floor system 摘要影响冷暖辐射地板系统的几个重要因素有供水温度、室内设计温度、埋管管距、埋管管径和地面层材料。 |
| 8. | In this paper , it emphasized on the influence of the supply temperature of the ground - water , the temperature difference between supply and return ground - water , the flow - rate of the well on the system , the difference area of heat exchangers 为了解决上述问题,我们建立了地下水源热泵系统实验台,采用实验和模拟相结合的方法,对系统的性能特性进行研究分析。 |
| 9. | Energy consumption of the building is monitored by the annual effective energy audit , and saving has been achieved with the introduction of various energy saving measures such as trimming fresh air supply for the air - conditioning system and raising chilled water supply temperature to 8 or 9 degree c during cooler seasons , etc 港大每年为大楼进行能源效益评核,所采取的节能措施效益显著,包括减少鲜风的供应量及在寒冷季节提高冷水供应的温度至摄氏8度或9度等。 |
| 10. | The experimental results showed that : in the summer operating mode , the refrigerating capacity and coefficient of performance of the system decreased with the increase of the temperature difference between supply and return ground - water and the water supply temperature ; in the winter operating mode , the refrigerating capacity and coefficient of performance of the system increased with the decrease of the temperature difference between supply and return ground - water and the increase of the water supply temperature . it also showed that , change the are of heat exchanger has great influence of refrigeration system 本课题通过实验测试井水进口温度、进出口温差以及在不同温差下换热器面积匹配对系统性能的影响。实验结果表明,夏季工况下,随着井水进口温度的升高,进出口温差的增大,系统制冷量减小,机组cop降低,系统运行性能恶化。冬季工况下,随着井水进口温度的升高,进出口温差的减小,系统的制热量增加,机组cop提高,系统运行性能优化。 |
