Desiccant cooling/dehumidification should be considered for the following circumstances:Where the cost of electricity is expensive or likely to increase substantially.Where possible the use of solar collectors could be utilised as a heat source to dry and re-generate desiccant materialWhen the latent load is high (i.e., when the latentto-sensible heat ratio is high), as they remove moisture more economically than they remove sensible heat.Where dehumidification is required at levels below freezing dew-point temperatures
