In this paper, performance analysis has been conducted to evaluate the regenerator with heat recovery in Liquid Desiccant Dehumidification System (LDDS) under different air mass flow rate. The waste heat of the exhausted regenerating air is recovered by a fixed-plate heat exchanger (FPHE). A hybrid model has been proposed for the heat recovery process and combined with the regenerating heat and mass...
To evaluate and compare the regenerator of liquid desiccant dehumidification system (LDDS) without and with heat pipe heat exchanger (HPHE), this paper conducts performance analysis by hybrid heat transfer, mass transfer and heat recovery models, and the simulation results are then validated by the experimental results. 4 and 8 rows HPHE are compared to investigate the relationship between heat recovery...
In this paper, a hybrid model for heat pipe heat exchanger used for heat recovery in regenerator of Liquid Desiccant Dehumidification System (LDDS) is developed. The proposed hybrid model starts from the physical governing equations and lumps the complex geometric parameters and fluids’ thermodynamic coefficients as constants since they have very small changes during the process operation. The resulting...
