A novel temperature and humidity independent control system (THIC) is proposed in this paper

and then experimental investigation of this system is conducted to evaluate its system performance. The THIC system is constituted of a novel solid desiccant heat pump (DESICA) to deal with the latent load and a variable refrigerant flow air conditioning system (VRV) to handle the sensible load. In order to verify the actual performance of this novel joint DESICA and VRV system (JDVS)

operation performance of this system is experimentally tested and compared with commonly adopted joint heat recovery ventilator (HRV) and VRV system (JHVS). These two hybrid systems are installed in an office room and operated on adjacent days during typical winter (Dec

2012 to January

2013) and summer (July

2013 to August

2013) season in Shanghai. From the experiment results

it is found that the proposed JDVS can provide better indoor thermal comfort while consuming less energy in both winter and summer season

compared with the traditional JHVS.
