Development of a Humidification-Dehumidification System in a Quonset Greenhouse for Sustainable Crop Production in Arid Regions

Preliminary testing of the performance of the greenhouse showed an increase in water vapour close to saturation after the second wall of cooling pads. The temperature of the water flowing in the dehumidifiers was always lower than the dew-point temperature of the air passing through them. Hence, condensation could occur and was observed on the dehumidifier. However, condensation was insufficient to result in a measurable quantity. Recommendations for design improvements of condenser are suggested.
