The hy I system consists of a conventional vapor compression type air conditioner and auesiccant dehumidification subsystem. The thermodynamic processes in the air conditioner obey a reversed Rankine cycle in which the compressor efficiency determinesthe compression process. The refrigerant in the air conditioner is assumed to be R-12.The desiccant dehumidification subsystem is composed of a rotary dehumidifier. a rotary heat exchanger and a regenerator. The regeneration temperation is 85 ℃ and theeffectiveness of the rotary heat exchanger is 0.95. The heat and mass transfer processin the dehumidifier is prescribed by four coupled nonlinear partial differential equations. A finite-difference scheme is used to solve the equations and the results areprovided to the system simulation analysis. The effects of the operation conditions of dehumidifier and the air conditioner on the system's (COP)m . (COP)q latent load ratio and specific cooling capacity are investigated.
