Low-temp. waste heat utilisation system - has heat pumps extracting heat from closed condenser cooling circuit

摘要

The system utilises low-temp. waste heat for heating purposes, derived from low-temp. water emerging from a power-station condenser. The waste heat from the condenser is conducted away either by the normal cooling water circuit or a separate low-temp. one. The water of the latter is brought in the condenser to a temp. allowing reasonable use of the waste heat, and fed by an adjustable circulating pump into a closed circuit with output and return sections. A number of heat pumps are connected to the outlet section, extracting the heat and returning the cooled water to the circuit. Pipe coils connected between the outlet and return sections of the circuit allow direct heat dissipation, e.g. for gardening and road-surface heating.
