摘要：

This communication presents an evaluation of various liquid dessicant cycles for air conditioning in hot and humid climates. Psychrometric evaluation of seven potential cycles for achieving standard comfort conditions (25-degrees-C/10 g/kg) in rooms has been carried out for 16 typical Indian cities. A computer simulation model is based on the constant effectiveness of heat exchangers (HX)/evaporative coolers (EC) and wet surface heat exchangers (WSHE). The absorber-cum-dehumidifier is assumed to provide air at the specified humidity. level, while the outlet air temperature is taken to be equal to the cooling water temperature. The effect of various outdoor conditions and the effectiveness of HXs/ECs on cooling COP and volumetric air flow rate per unit cooling capacity have been investigated. It was found that a combination of dehumidifier and WSHE is better, in terms of COP, for a wide range of outdoor conditions. The results should be useful in the design of liquid dessicant based air conditioning systems suitable for the monsoon season in tropical countries like India.
