As a step towards finding new sustainable building materials and structures, the division of Building Physics at the Department of Building and Environmental Technology at LTH performs experiments to evaluate heat- air- and moisture transport through the building envelope.<\/p>\n

One of the experimental setups is a hotbox where sections of exterior walls, including windows, doors etc. can be tested. Heat transfer properties and temperatures are measured to find insulation properties. Due to an outdated control system the hotbox had been out of order for over ten years. It was now time to get it up and running again. LTH saw possibilities for their own research as well as using it as an experimental laboratory for companies in the building sector.<\/p>\n

This required some reverse engineering to find out how to control the existing heater and cooler. The measurement hardware was replaced with new CompactDAQs from NI, and all sensors were replaced.\u00a0<\/span><\/p>\n The hotbox has two sides, one cold and one warm. These are separated when a test wall is placed in the hotbox. Therefore the control system hardware is split in two cabinets enabling a robust solution.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.9.3″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,1_4,1_2″ _builder_version=”4.9.3″ _module_preset=”default” width=”100%” custom_padding=”21px||0px|||” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.9.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”Text” _builder_version=”4.10.4″ _module_preset=”default” width=”100%” module_alignment=”left” custom_margin=”-5px||||false|false” custom_padding=”5px||0px|||” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.9.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”Text” _builder_version=”4.10.4″ _module_preset=”default” width=”100%” module_alignment=”left” custom_margin=”-5px||||false|false” custom_padding=”5px||1px|||” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.9.3″ _module_preset=”default” global_colors_info=”{}”][et_pb_testimonial author=”Lars-Erik Harderup” job_title=”Senior lecturer at Division of Building Physics” company_name=”LTH” disabled_on=”off|off|off” _builder_version=”4.9.3″ _module_preset=”default” author_font=”Open Sans|700|||||||” custom_margin=”-200px|||||” custom_margin_tablet=”0px||||false|false” custom_margin_phone=”” custom_margin_last_edited=”on|phone” custom_padding=”30px|||||” locked=”off” global_colors_info=”{}”]<\/p>\n \u201cDVel was easy to communicate with from the start. They listened and gave straightforward answers, enabling us to understand the solution already in the initial phase. During the project, DVel had answers to any questions we had, and they delivered what was promised. We also like their close relation to research, being able to relate to our operation.
