Abstract
This paper presents a theoretical feasibility study of three dehumidification systems to achieve air with dew points down to (−) 40 °C. The systems consist of compressors, heat exchangers, expanders and heaters. A thermodynamic model has been developed of the systems to study the effect of the compressor, expander, and heat recovery heat exchanger efficiency as a function of pressure ratio, net required work, quantity of condensed moisture, and system outlet dew point temperature. The analysis has revealed that the selection of a heat recovery heat exchanger is critical for an efficient dehumidification system, where compressor efficiency has the dominant effect on power consumption.
