<p>In order to be able to make use in a simple way for the purpose of vapourizing the refrigerant of a heat pump of the heat released when water freezes, a heat exchanger is proposed which has a heat transfer wall 5 between the refrigerant and water. Said wall is assigned a spraying device 8, connected to a water source, for the surface facing the refrigerant, which forms a runway for at least one roller body 12 for removing the incipiently freezing water. <IMAGE></p> |
