Application of stand-alone photovoltaic liquid desiccant air conditioning system in extreme hot-humid islands

Proposes a kind of stand-alone photovoltaic driven liquid desiccant air conditioning system which is suitable for the special environmental characteristics of extremely hot-humid islands, and analyses its principle and system process. Sets up a mathematical-physical model of each part of the system with the cooling load of 1 000 kW as example. Calculates the parameters of liquid desiccant units, air conditioning terminals and stand-alone photovoltaic system in the conditions of different values of angle scale, respectively, and obtains their optimal combination. The results show that when the total load is constant, the lower the angle scale, the larger the size of the desiccant unit, the smaller the size of the indoor terminal and the stand-alone photovoltaic system and the lower the total energy consumption of the system. Therefore, the stand-alone photovoltaic driven liquid desiccant air conditioning system is more suitable for the buildings with low angle scale.
