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。相对来说 ,离心式冷水机组的一次能源利用效率较高 ,燃气直燃型溴化锂吸收式机组的污染物排放量较小。选择冷源时如能将一次能源利用率及对环境的影响情况考虑进去 ,从而选择合适的冷源则更佳
Air conditioning has been widely used in various fields, and the use of air conditioning technology not only makes efficient use of energy but also has a huge impact on the environment. Air conditioning cold source types and diverse, different energy efficiency of different cold source, run-time emissions of pollutants are different. This paper compares the primary energy efficiency of different cold sources and compares their environmental impact. Relatively speaking, the centrifugal chiller unit is more efficient in primary energy use, and the gas-fired liquefied lithium bromide absorption unit has less pollutant emissions. When choosing a cold source, such as the primary energy efficiency and environmental impact can be taken into account, so the choice of a suitable cold source is even better
