Experimental Investigations on the Performance of a Packed Bed Dehumidifier for Various Climatic Conditions

ABSTRACT

To simulate space cooling or drying systems for various geographical regions (low, moderate, and high humidity regions) a liquid desiccant system consisting of a humidifier and dehumidifier has been designed and constructed. This system consists of two coupled humidifying and dehumidifying packed columns filled with plastic Intalox Snowflake packing material. Experimental measurements of the dehumidifier performance utilizing a new effective liquid desiccant mixture (CELD) total desiccant salt content 40%wt.to 45%wt (salt comprised of equal portions by weight of lithium chloride and calcium chloride ), have. been carried out, The effect of different independent variables such as packing height, air inlet temperature and humidity ratio, and liquid desiccant inlet temperature, flow rate and concentration on the performance of the dehumidifier has been investigated. Experimental results demonstrate that the CELD is a promising desiccant for cooling and drying operations.

Performance analysis of an innovative small-scale trigeneration plant with liquid desiccant cooling system

The paper deals with an innovative natural gas combined heat, cooling and power (CHCP) system with electrical, heating and cooling capacities of 126/220/210 kW, respectively. The trigeneration plant is composed of a cogenerator which uses an automotive derived gas fired internal combustion engine (ICE), coupled to a liquid LiCl-water desiccant cooling system which recovers heat from the flue gases and from the ICE cooling water. The paper describes the energetic and economic analyses of the plant and it makes some evaluations of the effects of fuel and electric prices and of the subsides and plant costs on the economic indices of the system.
