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 COPth of the system during the cooling season is 1.5,and the average power performance coefficient COPe 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%.
