| 摘 要： | 在国家建筑节能设计标准中的耗电输热比EHR的基础上引申得到了热水循环泵输送能耗与系统供热量的一次能耗比EHR'指标,并根据对海水源热泵区域供热系统EHR'指标的不同控制要求,得到了系统的最大供热半径.经计算,当热水供回水温差为10℃,海水源热泵区域供热系统的EHR'指标分别控制在5%,10%,15%,20%时,系统的最大供热半径应分别为0.875,2.75,4.625,6.5 km.

| Abstract: | On the basis of the ratio of electricity consumption to transferred heat quantity(EHR)propagated in the national building energy efficiency design standard,obtains the index of primary energy consumption ratio of hot water transportation to the heat supplied(EHR').Calculates the maximum heating radiuses of seawater-source heat pump district heating systems(SSHPDHS)under different indexes of EHR'.The calculation results show that if the indexes of EHR' are set at 5%,10%,15% and 20%,the maximum district heati... |
