ENGINEERING PROJECT RECORD / OUTCOME OPEN

Airflow modification at St. Regis

A 200 mm opening modification has recorded grille-velocity readings at high and low fan modes. Those measurements establish a local change; they do not confirm the occupant complaint or whole-room performance was resolved.

Selected photographs document St. Regis site work and equipment. They are not presented as a verified before-and-after performance comparison.

Equipment and detail

Air handling equipment in hotel project. From the St. Regis record; appearance alone does not establish a system outcome.

Project context

Hotel Or Residence HVAC work in St. Regis. The public record omits private unit numbers and identifies the documented system scope.

Request and scope

The selected St. Regis record does not establish the original customer request. The work sequence below is limited to the documented intervention.

Observed finding

The St. Regis grille measurement recorded high air velocity before the opening modification.

Engineering decision

The St. Regis work increased the opening and checked air velocity at different fan modes.

Documented work sequence

A 200 mm opening was cut during the St. Regis airflow work.

Systems in this scope

FCU, grille, ductwork and extract.

Site constraint

Concealed routes and checks at multiple operating modes shaped the St. Regis inspection.

Confirmed boundary and open outcome

The local measurement record states the opening dimension and grille velocity at defined fan modes. These findings do not establish whole-room air volume or complaint resolution.

8.5 → 6 m/s

High fan mode / grille velocity before → after

4.5 m/s

Low fan mode / recorded after the opening change

200 mm

Opening cut / dimension recorded for the work

No final occupant, noise or whole-room outcome is established by the selected measurements.

What this record helps you decide

Keep opening dimension, fan mode and measured velocity together. A local velocity reading is not a measurement of whole-room airflow, noise or comfort, and the source does not close those outcomes.
