Abstract: The fresh water and space conditioning are the human needs for comfort living. Humidification dehumidification - vapour compression refrigeration (HDH-VCR) cycle for combined portable water and air conditioning (A/C) has been studied with exergy approach. HDH-VCR cycle has been studied with thermodynamic exergy approach for efficient operation of the cycle. The focused options in this work are dehumidification with normal water (HDH), dehumidification with chilled water (HDH-VCR 1) and dehumidification with VCR (HDH-VCR 2). The exergy losses of the components are compared for these three units. As per the exergy analysis, HDH-VCR 2 has been highlighted with higher exergy efficiency compared to the others.

Keywords: air conditioning; humidification dehumidification - vapour compression refrigeration; HDH-VCR; exergy; psychrometry; second law of thermodynamics.
