A technical designer working at a computer workstation, developing an engineering drawing for a commercial refrigeration system. Set in a modern, well-appointed office environment with an open, minimalist aesthetic and large windows overlooking an urban skyscape. The designer should be shown intently focused on the computer screen, manipulating CAD software or other digital design tools to create a detailed schematic of the refrigeration equipment and system layout. Surrounding the designer should be technical reference materials, drafting tools, and other indicators of their specialized expertise. The overall scene should convey a sense of professionalism, innovation, and the importance of precise engineering in commercial HVAC and refrigeration projects.
