| Popis: | 106 Global warming causes the decrease of nature energy and resource. Environmental protection becomes the global trend. This study evaluates the before and after implementing of the improvement process of the air-conditioning and lighting system in C General Hospital, by comparing its annual power consumption, and also investigates the energy saving performance of the variable primary flow system of cooling water. In this study, regarding the current B4F air-conditioning equipment in the M Branch of C General Hospital, there are two 500 RT centrifugal chillers, one 300 RT screw chiller, three 1500 kg/hr gas steam boilers and four heats. The total annual power consumption counts: 4,431,889 KWH for electricity, 155,989 m³ for gas. For the lighting system, M Branch uses the traditional lamps, the total annual power consumption counts 214,109 KWH, the G park of C General Hospital uses the traditional lighting, the total annual power consumption counts 124,280 KWH, the P Campus of C General Hospital uses the traditional lighting, the total annual power consumption counts 65,153 KWH, the Hall C of C General Hospital uses the traditional lighting, the total annual power consumption counts 12,305 KWH, the C Comprehensive Rehabilitation Hospital also uses the traditional lighting, the total annual power consumption counts 28,606 KWH. The improvement process for M Branch air-conditioning system is to add the central monitoring system, to replace one 500 RT centrifugal chillers, and to add one 100 RT spiral heat pump. The system will be changed to one variable primary flow system, and be added a converter in the ice water pump and the cooling water pump. The reason to do so is to reduce operators' working load, to improve the equipment operating efficiency, and to decrease the energy use. As for the lighting system, the traditional light will be changed into LED light in the M Branch, G Park, P Campus, Hall C, and the C comprehensive rehabilitation Hospital of the C General Hospital, in order to enhance the wire line stability and to reduce its load. By means of the above methods, the air-conditioning and lighting energy consumption can be reduced, the cost can be saved as well, and the goal of power saving can be achieved. |
