Description

Condenser evaporator for periodic absorption chillers The The invention relates to a condenser evaporator for a primarily composed of cooker absorber, Water separator and condenser evaporator. the cold development of which is triggered by turning it around about go ° after cooking and its condenser-evaporator is provided with a central cavity. The E: finding is that the size of the liquid surface in the condenser evaporator: with continuing evaporation, i.e. from top to bottom, increases, whereby the The intensity of the evaporation is increased to the degree to which the absorption activity decreases in the cooker absorber as a result of the increase in saturation. This causes an ongoing uniform cold development and extends its duration.

This increase in the surface area of the liquid can e.g. B. achieved thereby be that the middle cavity of the condenser evaporator down or the Sheath of the same is conically shaped decreasing towards the top.

Conical cavities that narrow downwards are found in evaporators has been used, but only for the purpose of that which has formed in the cavity To be able to remove ice block more easily, whereby the cavity was very weakly conical, so that the present invention object could not be achieved. Also are more conical evaporators known, but their evaporation space in contrast to the invention decreases downwards.

This is intended to increase the length of the wetted inner surface of the cavity The beginning of the cold development should be kept upright to a greater extent. This creates but unevenness of cold development and shortens its duration in such a way that Such machines for the permanent cooling of storage rooms are unusable and only suitable for making ice cream.

In the drawing are several exemplary embodiments of FIG Shown condenser evaporators according to the invention and shows Fig. I and 2 a Refrigeration: go into view in cooking and cooling position, in the latter the evaporator in section along the line A-A of Fig. i, Fig, 3 to 5 embodiments of the condenser evaporator on average.

It denotes = the cooker absorber, 2 the water separator, 3 the connecting pipe both, q. the condenser evaporator and 5 its middle cavity. The latter narrows conically downwards according to Fig. 2 and q., the outer jacket being cylindrical is. According to Fig.3, the cavity is cylindrical and the outer jacket is conical at the top decreasing. According to Fig. 5, the cavity decreases to a conical shape and the outer jacket upwards to be conical. By these designs it is achieved that the liquid surface increases in the condenser evaporator as evaporation continues, since the evaporation space steadily increasing conically from top to bottom.

The cavity 5 can be closed at the bottom (Fig. 2) or by a Lid 6 (Fig. Q.) Or an insertable sundae 7 (Fig. 5) are closed, in order to accumulate the cold in the cavity when ice is produced.
