Study of open-cycle sorption heat pumps. Doctoral dissertation.

Etude des pompes à chaleur à sorption à cycle ouvert. Thèse de doctorat.

Type of monograph: Doctoral thesis

Summary

The objective of this study is to recover heat from a drier. The author designed a process that notably increases the output of a drier, through coupling to an open-cycle sorption heat pump. This system makes it possible to use the calories recovered at the drier outlet through water-vapour sorption in a hygroscopic material which is either a concentrated solution of lithium bromide or calcium chloride, or a silica-gel fixed bed. The author made modellings. Extract from the table of contents: general considerations on open-circuit heat pumps; air dehumidification with a hygroscopic material with a view to using it for drying foodstuffs; study of the drying process using a hygroscopic solution; study of the drying process using an adsorbing solid; possibilities of producing water with atmospheric air ("humi-sorb" process).
