各种冷源的一次能耗及对环境影响的比较

空调已广泛运用于各个领域，空调技术的使用不仅对能源有效利用而且对环境产生巨大影响。空调冷源型式多样，不同的冷源能源效率不同，运行时污染物的排放情况不同。本文对不同冷源的一次能源利用效率进行了比较，并且比较了它们对环境影响的情况。

Primary Energy Consumption Impact on Environment of Different Cold Sources

Air conditioning has been widely used in all fields.The technology concerning how to use it will not only affect the effective utilization of energy,but also have great impact on environment.There are many different kinds of cold sources and each has different energy efficiency and contamination discharge when running.Primary energy efficiency and impact on environment of different cold sources have been compared in this article.In conclusion,primary energy utilization efficiency of centrifugal chiller is relatively high and contamination discharge of gas direct-fired lithium bromide absorption chiller is relatively low.It will be better considered primary energy utilization efficiency and impact on environment when choosing cold source.
