Abstract
The invention relates to a method and apparatus for low temperature waste heat utilization. In the scope of the cogeneration unit (CHP) there are few low temperature sources, which cannot be used by heat consumer (HC) directly. Hence, the method and apparatus for cogeneration power plant waste heat recovery comprise at least one, preferably condensing type heat exchanger (HE2), which collects the waste heat for water source high temperature heat pump (HP) employment, wherein its hot water outlet is fed to the internal combustion engine (ICE) cooling system, i.e. cooling jacket type heat exchanger, wherein the maximum allowed coolant inlet temperature is achieved and maintained by automated control system (i.e. control unit with motorized control valves (V1-V3)). It is important to notice, that low temperature sources are herein represented by the exhaust gas in the scope of exhaust system, the charging air in the scope of the intercooler or turbo-supercharger, and lubrication oil cooling system in the scope of internal combustion engine (ICE) or heat pump (HP).
