| Popis: | 102 The purpose of the study is to achieve the effects of energy saving and carbon conservation for chiller through the use of far infrared material. By the way of external coating, heat exchanger of chiller can be cladded by far infrared material. Such a non-destructive installation way is feasible to achieve energy saving effect and apply to engineering. Experiments were made to explore heat exchange efficiency ratios of tube exchangers under the same influent temperature, flow speed and heat exchange area. Finally, far infrared material was applied to chiller system so as to understand the effects of actual application of mid- and far-infrared materials on the COP and refrigerating capacity of system, and analyze the feasibility of such application. Experimental results show that when Reynolds number is 1500 during application of commercial-use far infrared material to tub exchanger, heat exchange efficiency rises by 4.4~8.8%; and when Reynolds number is 3500, heat exchange efficiency even rises by 7.8~13.4%. As known from the actually measured results of chiller, the system has its COP grown by 11.9% and its refrigerating capacity risen by 14.4% maximum. The far infrared material employed in the experiments of the paper can really enhance the effectiveness of heat exchange device during operation. Meanwhile, external coating is an ideal installation way since it can greatly raise the feasibility of its actual application in future. |
