<p>Method and equipment for the utilization of the freezing heat contained in water as a source of heat of a heat pump. The water flow to be utilized as the source of heat is evaporated in one or several stages (4) at such a low pressure that, when the vapour that is formed binds its evaporation heat out of the water, part of the water freezes. The vapour formed is condensed in one or several heat exchangers functioning as the evaporator of the heat pump, whereat the vapour, on being condensed, delivers its heat to the heat transfer medium used in the heat pump.</p> |
