Patent number: 11346255Abstract: A method for preventing formation of droplets in a heat exchanger, in which a second medium transfers heat to a first. The method is performed by a controller which receives different temperature values (T1, T2, T3) and a pressure (P) value to be used for calculating a boiling point temperature value (TB) and determining a first temperature difference (?T1) and a second temperature difference (?T2). Generating a flow control signal, for controlling the flow of the first medium into the heat exchanger, based on the first temperature difference (?T1), the second temperature difference (?T2) and the first temperature value T1 and sending the flow control signal to a regulator device for controlling the flow of the first medium in the heat exchanger.Type: GrantFiled: December 10, 2019Date of Patent: May 31, 2022Assignee: CLIMEON ABInventors: Esko Ahlbom, Rikard Pettersson

Publication number: 20200200483Abstract: A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising CO2, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of CO2 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two-component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.Type: ApplicationFiled: October 7, 2019Publication date: June 25, 2020Applicant: ClimeOn ABInventor: Esko AHLBOM

Patent number: 10082030Abstract: Expansion machines in thermodynamic cycles operate at low pressures, i.e. below 10 bar. The interplay among components including gas generator, expansion machine, heat exchangers and pressure reduction device (absorber or condenser) is optimized, resulting in configurations operating at the lowest achievable cost level. A single stage radial turbine characterized by a pressure ratio of 5-10, a dimensionless speed of about 0.7 and a loading coefficient of 0.7 is a preferred expansion machine for certain thermodynamic cycles involving CO2 gas to permit such radial turbines to operate close to their optimum design specification and highest efficiency level. Methods to handle liquids which may condense within or inside the turbine are also disclosed, as well as methods to handle axial pressure on bearings and methods to protect lubricant in bearings.Type: GrantFiled: January 20, 2015Date of Patent: September 25, 2018Assignee: Climeon ABInventors: Magnus Genrup, Olle Bergström, Joachim Karthauser, Kari Munukka, Esko Ahlbom, Per Askebjer
