A High Capacity Thermal Energy Storage for Separate Sensible and Latent Cooling
Published Wednesday, September 16, 2015Background:Conventional air conditioning systems utilize low temperature evaporators to cool and remove moisture from hot and humid air. In order to remove the moisture, the air temperature has to be below the dew point of the indoor air. However, the dew point temperature is usually lower than the temperature required for the conditioned...
