Energy consumption of LT-MED seawater desalination system equipped with heat pump
摘要
由于低温多效海水淡化系统有大量的低温余热被浪费
造成系统的能耗增大
而热泵可以将低温热能提升为高温热能
所以热泵与低温多效系统联合运行可以使热量得到最大化的利用。对此
通过对有、无热泵应用于低温多效的循环系统进行计算研究
得出有热泵参与时
整个系统的单位能耗为23.27(k W·h)/t
是无热泵低温多效系统单位能耗的1/7倍。因此
热泵应用于低温多效系统可使海水淡化系统的能耗显著降低
并达到节能环保的目的。
Abstract
Due to waste of large amount of low temperature waste heat
the low temperature multi effect distillation( LT-MED) seawater desalination system's energy consumption is increased. Since the low temperature heat can be transferred into high temperature heat by heat pumps
the combined operation of heat pump and LT- MED seawater desalination system can make full use of the heat. Thus
investigation on the LT-MED system equipped with and without heat pumps was conducted. The results show that
when the heat pump was applied
the unit energy consumption of the whole system was 23. 27( k W·h) / t
which is about 1 /7 times of that of the LT-MED system without heat pump. Therefore
application of heat pump in the LT-MED system can reduce the energy consumption effectively.
