A regeneration unit characterised by: a housing (11); a compartment (21) in the housing divided into two working volumes (22, 23) separated by a partition (24) whose position within the compartment (21) can be varied so as to vary the relative sizes of the two working volumes (22, 23); and a control means whereby a flow of air can be directed into each working compartment independently so that the temperature level and time of heating or cooling of material contained in one working volume (22, 23) is independent of temperature level and time of heating or cooling of material contained in the other working volume (23, 22). Typically the unit is further characterised in that each working volume (22, 23) is incorporated in a closed flow path which incorporates: means (26, 27) for displacing air around the flow path; and heat transfer means for heating or cooling air displaced around the flow path. |
