ENERGY EFFICIENT SOLUTION IN THE BREWING PROCESS USING A DUAL-SOURCE HEAT PUMP.

In this paper, the investigation of an experimental heat pump equipment is presented. This equipment is capable of serving two different temperature cooling needs and a given temperature heating demand within a given industrial process, adapting to its time and performance requirements. The use of a heat pump is energetically advantageous, if a nearly continuous operation can be realized in the course of an industrial process to serve simultaneous cooling and heating needs. In the field of brewing, it was demonstrated by model experiments that CO2 emissions can be reduced by 60% with a 10% reduction in energy costs if the energy requirements are satisfied using a dual-source heat pump.
