Sažetak

This paper deals with the possibilities for the reduction of thermal environmental pollution and increases in the efficiency of the condensate system of a turbine by installing an inverter heat pump system. The inverter heat pump system will use the heat energy of the turbine exhaust steam that would otherwise be rejected. The operation of a condenser cooling system in a heating plant will be presented, and the possibilities of an inverter heat pump system installation will be analysed. The envisaged waste heat recovery system will be presented and analysed. The analysis will involve an evaluation of exergy and anergy efficiency of the system to minimize the generation of entropy, thus reducing the irreversibility of the system. Some guidelines regarding the utilization of heat energy generated by the inverter heat pump system and the impact of the utilization of heat on turbine efficiency will be indicated.
