HVAC-Integrated VHP for Multi-Room Cleanroom Suites<\/h1>\n

When a whole suite \u2014 and the ductwork serving it \u2014 must be decontaminated, carrying VHP through the existing air handling system reaches every room from one fixed unit, instead of moving mobile generators room by room.<\/p>\n

The challenge<\/span>

Why this needs a VHP step<\/h2><\/div>\n

Mobile generators treat one room at a time and never reach the inside of the ducts. In a multi-room aseptic suite that means long shutdowns, repeated set-ups and an untreated air path feeding the rooms.<\/p>

An HVAC-integrated system injects vapour into the air handling loop. The AHU distributes it through supply ducts, rooms and returns, then helps aerate the suite when the cycle ends.<\/p><\/div>\n<\/div><\/section>\n\n

\n Engineering & validation<\/span>

What to plan for<\/h2>\n
01<\/span>

Survey the AHU first<\/h3>

Fresh-air intake and exhaust must be closed with tight dampers so the suite runs on full recirculation during the cycle. Check damper leakage before anything else.<\/p><\/div>

02<\/span>

Materials in the air path<\/h3>

Coils, filters, duct sealants and humidifier sections all see the vapour. Confirm materials, and decide whether humidifiers and cooling coils are bypassed or controlled during the cycle.<\/p><\/div>

03<\/span>

Balance between rooms<\/h3>

Rooms with very different volumes or air-change rates reach target concentration at different times. Sensor positions and the qualification BIs should cover the slowest room, not the average.<\/p><\/div>

04<\/span>

Integrate with the BMS<\/h3>

Decide which system controls AHU mode, dampers and alarms during the cycle, and how the suite is locked against entry until residuals are confirmed.<\/p><\/div>

05<\/span>

Aeration through the HVAC<\/h3>

After exposure, the AHU and catalytic breakdown bring the suite down to the release limit. Fresh-air purge can shorten aeration if the exhaust route is acceptable.<\/p><\/div><\/div>\n<\/div><\/section>\n\n
