A heat recovery system arranged to be used together with a first closed loop system (S) configured as a first closed-loop thermodynamic Rankine cycle system, to convert heat from a heat generating unit () into electrical energy (E). Said heat recovery system comprising a second closed loop system (S) comprising a second system working medium (W) configured as a second closed-loop thermodynamic Rankine cycle system arranged to convert the heat in at least one heat stream (HS) generated by the heat generating unit () into a first batch (E) of electrical energy (E) and a third closed loop system (S) comprising a circulating third system working medium (W). In the second closed-loop thermodynamic Rankine cycle system the condensation heat enthalpy of a vaporised second working medium (W) is transferred to said third system working medium (W) and the heat from the third system working medium (W) is used as an initial thermal input to the second closed loop system (S), thus converting heat from the third system working medium (W) into a second batch (E) of electrical energy (E). The invention also relates to a method to use a heat recovery system together with a first closed loop system configured as a first closed-loop thermodynamic Rankine cycle system, to convert heat from a heat generating unit into electrical energy.

Heat recovery system and a method using a heat recovery system to convert heat into electrical energy

A method for producing electrical energy is disclosed which uses a heat source, such as solar heat, geothermal heat, industrial waste heat or heat from power production processes, providing heat of 150&#xb0; C. or below, further comprising an absorber system in which a working gas, primarily carbon dioxide CO, is absorbed into an absorbent, typically an amine, further comprising a reactor which receives heat from said heat source and in which the absorbent-COmixture is split into COand absorbent, further comprising an expansion machine, an electricity generator and auxiliary equipment such as pumps, pipes and heat exchangers. The system according to the method allows the cost-efficient production of electrical energy and cooling using low value heat source.

Method for conversion of low temperature heat to electricity and cooling, and system therefore

A method of patterning a plurality of layers of a work piece in a series of write machines, wherein errors due to different transformation capabilities of different machines are compensated by distributing the errors over the plurality of layers.
