This paper discusses 2 examples of using waste heat from a brewery cooling process with heat pumps. The first example is the transfer of condensation heat to the heat usable for bottling, mashing or in the return flow of a district heating system to increase the water temperature. The second is the use of superheating heat to increase the return water temperature of a district heating network or mashing, lautering or bottling. Both possible solutions for the use of heat pumps offer real possibilities of introducing part or all of the waste heat of the cooling system to the level of useful temperatures. The 1st concept (usage of heat of condensation and discharge gas heat) is much more interesting because it gives real savings for the plant and possibilities of selling heat to an external recipient. The temperature level is also sufficient to cover all own technological purposes at temperatures up to 70°C.References
