A heat pump model with a transparent side panel at the Carel stand reveals its compressor, controller and valves, with the refrigerant circuit traced in neon lines. The plinth is labelled "Heat Pump Solutions", and a "Residential HVAC" display stands to the left as visitors gather under the red Carel fascia.
