Abstract

To achieve the energy consumption index of near zero energy buildings, a desiccant cooling system with heat pipe is proposed in hot and humid area. The desiccant cooling system with heat pipe can be driven by three different solar systems, respectively. The system is modeled by TRNSYS and verified by the experimental platform. The annual operation of the solar driven desiccant cooling system is simulated dynamically. The simulation results show that after outdoor fresh air is processed by the solar driven desiccant cooling system, indoor temperature and humidity can meet the requirements of human thermal comfort. Among them, the heat pipe solar driven desiccant cooling system with photovoltaic photothermal system has the lowest power consumption and the highest refrigeration coefficient (COP) is 2.1. Compared with the traditional air conditioning system, the COP is increased by 2 times and the annual average energy consumption is reduced by 64.7%.
