| 中文摘要: |
| 介绍了一种新型的高效节能中央空调冷暖系统－自备发电、余热利用及热泵冷暖系统。该系统充分发挥了大型建筑必备设备－自备电源应急柴油发电机的作用，使一次能源在使用中更加符合热力学的原理；该系统不追求某一种机组的高COP，而是利用各种设备的优点，有机匹配,以求一年中最高效的节能。通过与三种常规冷暖系统的一次能源利用率比较，得出该新型冷暖系统的一次能源利用率比三种常规冷暖系统的一次能源利用率高27．88％－104．6％以上。并通过实例计算了采用该系统的某大型广场的全年经济效益。 |
| 英文摘要: |
| In large and medium-sized cities, where there are no heat supply networks of steam or hot-water available and coal-fired systems are not allowed to be used in consideration of air quality control, three basic types of the central air-conditioning system can be used in large buildings: (1) the system consisting of a water chiller and an electric heating boiler or an oil-fired boiler; (2) the air-cooled heat pump; (3) the direct-fired LiBr absorption chiller. Based on an analysis of primary energy efficiency of the three types of central air-conditioning systems, a new type of high-performance, energy-saving central air-conditioning system was presented. This system brings the function of the emergency Diesel-electric generator necessary to large buildings into full play and takes advantage of other installations in the system to attain a higher energy utilization efficiency. Compared with the conventional systems, the primary energy efficiency COP of the new type central air-conditioning system is increased by over 28%. By a case study, the annual profit of a large building using this type of system was calculated. |
