摘要:
为减少辐射供冷系统热湿处理机组的能耗,提出采用两级热泵与除湿单元联用的系统形式.低温热泵子系统提供辐射供冷所需的冷负荷,高温热泵子系统则根据设计的系统形式大小不同,可长期运行,也可与蓄热水箱或者太阳能联用3种方式.并对3种方式下的液体除湿、固体除湿与传统的冷却除湿,液体除湿+冷水机组和固体除湿+冷水机组的形式进行能耗分析对比,结果表明3种方式下的液体除湿和固体除湿系统都较节能,且以3种改进方式与液体除湿联用的系统最为节能,与冷却除湿相比,能源消耗可以减少48%.
Abstract:
In order to save ene rgy o f heating and dehum idify ing unit in radiant cooling sy stem, it is proposed tha t the comb ined use of two-stage hea t pum p and dehum idify ing unit. Low- temperature- stage hea t pum p is used to supply coo-l ing load of rad iant cooling system, and h igh-temperature-stage hea t pum p is designed in three shapes. One is low load system that is only to dehum id ify w hen the room is need to, the o ther tw o are not on ly dehum idify ing but also are comb ined w ith heat sto rage water tank or so lar energy. And the energy consumption ana lys is is done on the new system style o f liquid dehum idify ing, so lid dehunidify ing, and coo ling de fum id ify ing, in contrast to liqu id dehum id ify ing+ w ater ch i-l ler, and so lid de fum id ify ing+ w ater chiller. The results show that liqu id and so lid dehum id ify ing arem o re energy- saving, and the th ree new system + liqu id dehum id ify ing is the m ost energy-sav ing and the energy consum ption is reduced by 48% w hen com pared w ith coo ling dehum idify ing.
