Abstract
An evaporative chiller utilizes an evaporative-cooled gypsum-ceramic casting to chill air passing through a passageway formed within the casting. Placed within an outer housing, the gypsum-ceramic casting has an outer wicking layer that maintains water saturation of the casting. Nano-evaporation from the casting surface into the air passageway cools the casting. Water is provided to the wicking layer from a supply connected to the outer housing. The chiller may be placed in-line within air ductwork, and blowers may be used to enhance the flow of air to be chilled through the evaporative chiller passageway.
Claims20
An evaporative chiller comprising:
- an outer housing, said outer housing having an inner surface that defines an air through-passage within said outer housing;
- a wicking layer attached to said inner surface of said outer housing;
- and
- a gypsum-ceramic casting layer extending over and attached to said wicking layer.
An evaporative chilling unit comprising:
- a cast matrix having an outer surface and an inner surface, said inner surface configured in a manner defining an air through-passage;
- a wicking layer formed over a substantial extent of said outer surface of said cast matrix;
- and
- an outer housing having an outer surface and an inner surface, said inner surface attached to said wicking layer.
