摘要： The method and apparatus for increasing the efficiency of a low-temperature or high temperature heating system, comprising a primary heat releasing unit (i.e. cogeneration unit with fuel cell (FC) or internal combustion engine (ICE)) for co-generation of the heat and power, and at least one secondary heat releasing unit (i.e. heat pump (HP)) for utilization of at least one of the available waste/renewable energy heat sources (HS) from the ambient (A), where the heat generated by said heat pump is preferably used for preheating the heat transfer medium in the return line of the closed loop heating system, wherein a primary heat releasing unit is used to heat the heat transfer medium to the required temperature level of the heat distribution network. The apparatus according to the invention may comprise one or more heat pumps (HP) of the same or different types, and one or more primary heat releasing units in serial, parallel or cascade connection circuits.

摘要： 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).
