This is partly attributable to R290's excellent thermodynamic properties and partly to the system's unique operating condition of using the MVHR exhaust airstream for heat rejection rather than ambient outdoor air.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary style=\"background:#008377CF; color:#fff; padding:12px 16px; cursor:pointer; font-weight:600; list-style:none;\"\u003eWhat support does Casavent provide for Cool Breeze Plus projects?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:14px 16px; background:#fff; font-size:0.93em;\"\u003eCasavent provides \u003cstrong\u003efull end-to-end design support\u003c\/strong\u003e for Cool Breeze Plus + Maxi Plus BY projects, including overheating assessment guidance, full system specification and design, CAD drawings, airflow and pressure calculations, and complete component breakdowns.
