condensate heat is emitted to the environment fig2 illustrates a cooling and heating rod which operates in accordance with the same principle as the cooling and heating plate of fig1 for cooling the water 21 is immersed into a liquid for heating the zeolite container 23 and the magnetic valve 22 is opened for reactivating purposes the zeolite filler 24 in the zeolite container 23 is heated to about 250 u00b0 c and the escaping steam is condensed on the water container wall 21 the absorbable material 26 distributes the condensate uniformly fig3 illustrates a further embodiment of the invention in the form of a combined cooling and heating pouch the sectional fig illustrates an insulation box 37 and a cooling and heating device in accordance with the invention in lid 38 the lid 38 is designed as a reverse lid so that the cooling water container 31 or the heating zeolite container 33 point into the inner chamber of the insulation box 37 depending on the intended purpose the cooling or heating operation is also activated by actuating the shut off device 32 or is interrupted by the shut off device a thermostatically controlled heating device 39 is mounted on the outer face of the zeolite container for reactivating the zeolite filler 34 to make sure that the reactivation of the zeolite filler 34 does not occur when the pouch is closed for safety reasons the current supply cable and the associated operating switch are so disposed that a regeneration cannot occur when the pouch is.
