WORK HISTORY
Mechanical Engineer @Dehumidified Air Solutions
Montreal, QC, CA
Mechanical Engineer in the R&D team, responsible for designing and optimising commercial and industrial HVAC equipment (5-120+ Tons) across the full product lifecycle- Designed Compressor Wall Technology - a modular, scalable system of independent refrigeration modules interconnected via a hydronic loop, improving reliability, energy efficiency, and reducing refrigerant charge for indoor pool and agronomic HVAC applications- Designed a modular fan array supply air system enabling component-level redundancy, improved airflow control, and enhanced system reliability- Led feasibility and design of two Energy Recovery Systems: a Glycol Run Around Loop with integrated Heat Pump (117% active energy lift vs. passive) and an Exhaust Air to Pool Water Heat Pump- Authored technical white papers and presented ROI analysis to senior management- Redesigned product lines for A2L refrigerant compliance (R454B)- IP54 enclosures, gas leak detection and purge systems- Increased system SCCR rating from 5kA to 65kA across product lines per CSA electrical standards- Recalculated refrigerant charge volumes after HX design change using 3D CAD volumetric analysis and FLIR thermal imaging validation- Diagnosed and resolved water ingress and condensation issues in electrical panels caused by negative air pressure and thermal bridging- Resolved critical COVID supply chain disruptions, sourcing and approving alternative components- Assisted the development of the Engineering Support Request Ticketing System (ESRT) to improve cross-team workflow
