Makatec Spiral Heat Exchanger for Heating and Cooling
Outline Introduction of the Makatec GmbH and Makatec Apparate GmbH Technologies Heat Exchanger (HEX) Applications of the HEX Role in the Project WP 3 - Heat Exchangers made of Plastic Materials WP 5 - Putting into Practice Summary 2
Makatec GmbH + Makatec Apparate GmbH are two companies with their registered office in Bondorf. Bondorf is a village in Baden-Württemberg, about 45 kilometres south-west of Stuttgart Makatec GmbH was founded in the year 2005 in the year 2008 Makatec Apparate GmbH was founded as subsidiary for the commercialisation of the Makatec HEX technology Makatec Apparate GmbH received exclusive licenses for the production of the protected Makatec HEX foreign distributors for Italy, Spain, Ireland are working with Makatec Apparate GmbH, negotiations with further partners in Turkey and France will be finished soon 3
Makatec Technologies Makatec develops new technologies and produces apparatus to improve heat and mass transfer: Heat exchanger based on polymer material (HEX) no corrosion Membrane contactor with integrated heat exchanger (MECO) " improved heat and mass transfer Absorption technology for heating and cooling compact design using Makatec HEX and MECO especially for small units below 10 kw heat input International patents have been granted for these technologies. 4
Makatec Heat Exchanger The first Makatec product is the Makatec heat exchanger low cost (polymers) no corrosion compact and low weight Main applications are aggressive anorganic liquids sea water well and hot spring water Makatec heat exchanger 5
Spiral HEX Basic Design pressure resistant design counter current flow outlet film for fluid separation spacer guarantee turbulent flow only polymer materials easy adaptable to specific boundary conditions inlet housing 6
HEX Application Today The combination of a Makatec polymer HEX and a standard heat pump enables the so far unexplored energetic use of sea water as a source of heat. 7
HEX Possible Future Applications cooling of acids and caustic solutions oil cooler in cars sea water desalination industrial waste water treatment 8
Role in the Project main partner of the UPB supply know-how on plastic wound heat exchanger to partner UPB validate the theoretical results of UPB 9
WP 3 - Heat Exchangers made of Plastic Material Proposing new materials of improved economic and environmental performance as heat transfer media to analyse configurations for plastic heat exchanger units to develop and validate accurate CFD models for the detailed description of the flow field and heat transfer in complex-geometry heat exchangers to improve the heat exchanger performance by adjusting both operating conditions and equipment geometry 10
WP 3 - Heat Exchangers made of Plastic Material 3.1 Basic design parameters for a spiral wound plastic heat exchanger basic data are prepared by Makatec and delivered to the UPB 3.2 Modelling of complex flows within a spiral wound heat exchanger Makatec will provide experimental data from the plastic heat exchanger units for validation against the advanced 3D CFD models developed by UPB 11
WP 3 - Heat Exchangers made of Plastic Material 3.3 Optimisation of the heat exchanger geometry and operating conditions improvement of the heat exchanger performance by adjusting both equipment geometry and operating conditions examination of the effect of the apparatus geometry on the pressure drop and heat recovery. Improvements will be suggested optimal operating conditions in terms of higher flow throughput, lower need on cooling/heating medium and higher heat transfer rates will be investigated by UPB and Makatec 3.4 Experimental validation of the improved geometry based on the theoretical results of UPB, Makatec will develop a optimised prototyp and compare it experimentally with today s Makatec standard type 12
WP 5 - Putting into Practice Demonstration of applicability and economic-environmental benefit of novel heat-transfer enhancement techniques and the new design methods proposed implementation of the technologies and design tools developed in the WPs 1-4 at industrial-scale production site in the process industries enabling the real-life validation and demonstration of the findings, know-how and inventions realistic quantification of techno-enviro-economic benefits, compared to conventional heat exchangers gaining valuable feedback for enhancing practicality of technologies developed from the projects 13
WP 5 - Putting into Practice 5.1 Demonstration and application of spiral plastic heat exchanger polymer materials have to be identified for an application of the new heat exchanger design for cooling of strong acids like sulphuric or hydrochloric acid if possible, a demonstration in the temperatur range above 100 C will be erected, leading to the requirement of advanced polymer materials with higher temperature resistance compared to Polyolefins 14
Summary main partner of the UPB know-how in constructing of HEX delivering basic data for a spiral wound plastic heat exchanger to the UPB developing a optimised HEX based on theoretical results of the UPB validating against the advanced 3D CFD models of the UPB with experimental data new polymer materials have to be identified for an application in strong acids 15
