Abstract

A method for starting operation of a thermodynamic system (100), the thermodynamic system comprising an evaporator (1) in the form of a plate heat exchanger (15), a condenser (2), a turbine (3), a generator (4) and a fluid pump (5), wherein the fluid pump (5) is arranged to circulate a working fluid in the thermodynamic system (100) to alternate between a liquid phase and a gaseous phase, wherein the plate heat exchanger (15) comprises a lower port (22a) in fluid communication with the fluid pump for ingress of liquid working fluid and an upper port (21a) in fluid communication with the turbine for egress of gaseous working fluid, wherein the method comprises introducing liquid working fluid into the upper port of the plate heat exchanger whilst preventing introduction of liquid working fluid into the lower port. Evaporated working fluid is directed from the evaporator to the turbine.
