摘要
采用一次能源利用率PER的概念 ,对目前广泛应用的空调冷热源直燃型溴化锂吸收式机组和电动风冷热泵机组作了比较。指出在额定工况下 ,直燃机一次能效率要高于风冷热泵。即使在考虑冷却系统能耗的情况下 。
The characteristics between two commonly used cooling/heating source-Direct Fired Absorption Chiller (DFAC) and electric-driven Air Source Heat Pump Chiller (ASHP) are compared by the concepts of Primary Energy Efficiency Ratio (PER). It is stated that the primary energy efficiency of DFAC is higher than ASHP under the rating condition. Also the primary energy efficiency of DFAC is higher than ASHP even through the energy consumption of condenser cooling systems is considered.
