摘　　要：为了充分利用矿井水的低焓地热能,文章构建了太阳能和矿井水互补转轮除湿空调系统,系统用低温矿井水处理显热,用转轮除湿机处理潜热,太阳能和高温矿井水互补驱动转轮除湿机再生。在TRNSYS中进行了建模和模拟。结果表明:当低温矿井水水温≤16℃时,可满足系统显热冷却要求。高温矿井水水温为40℃时,制冷季82.8%的再生热量由矿井水源热泵提供,其余再生热量由太阳能提供。系统制冷季平均热力性能系数COP_(th)为1.5,平均电力性能系数COP_(e)为2.2。与传统蒸汽压缩空调系统相比,太阳能与矿井水互补转轮除湿空调系统节能率可达到55.8%。In order to make full use of the low-enthalpy geothermal energy of mine water,a solar and mine water complementary desiccant wheel air conditioning system is proposed.The system uses low-temperature mine water to treat sensible heat,and the rotary dehumidifier is used to treat latent heat,and solar and high-temperature mine water complementary drive rotary dehumidifier regeneration.Modelling and simulation are carried out in the TRNSYS.The results show that when the temperature of the low-temperature mine water is 16℃and below,it can meet the sensible heat cooling requirements of the system.When the temperature of the high-temperature mine water is 40℃,82.8%of the regenerative heat during the cooling season is provided by the mine water source heat pump,and the rest of the regenerative heat is provided by the solar energy.The average thermal performance coefficient COP_(th)of the system during the cooling season is 1.5,and the average power performance coefficient COP_(e) of the system during the cooling season is 2.2.Compared with the traditional vapor compression air conditioning system,the energy saving rate of the solar and mine water complementary desiccant wheel air conditioning system can reach 55.8%.
