Abstract
A high temperature regenerator for an absorption water cooling and heating machine for extracting steam as coolant by heating and condensing a dilute solution of lithium bromide. An inner casing (2) defines therein a combustion chamber (11B) on the blow out port side of a burner for blowing out combustion gas. The solution is filled in liquid chambers defined in an outer casing (1) above and below the combustion chamber. A coolant vapor outlet passage (8) is defined in the upper part of the outer casing, and gas exhaust passages (13, 14) are defined in the combustion chamber on a side remote from the burner. A plurality of solution tubes 3 communicated with the liquid chambers above and below the combustion chamber are extended through he combustion chamber. The plurality of solution tubes are plane tubes having fins (16) at their side surfaces. The fins are provided only on the upstream side. With these fins, the heat-exchange between the solution filled in the plane tubes and the combustion gas can be promoted so as to promote the flow of the solution.
