Abstract:
In this paper,the condensation heat of vapor compression refrigeration system and solar energy are used as auxiliary heat source in the solution regeneration process.A novel hybrid liquid desiccant air conditioning system is established with efficiently sectional utilization of condensation heat.The ε-NTU model is used to conduct the theoretical analysis of the system.The paper studies the effects of indoor sensible heat load ratio,outdoor air condition as well as fresh air ratio on the performance of the system,and compared the results with the conventional liquid desiccant air conditioning system which does not utilize condensation heat as auxiliary heat source.It is concluded that even if electrical energy is used to assist regenerating solution,the system’s performance is better than that of the conventional system without utilization of condensation heat.The promotion will be more especially when ta and RH are relatively little.
