Case Study: From Survey to First Air — A Shanghai Restaurant Installation
The project
This system was installed in a restaurant in Shanghai that kept trading throughout. What follows is the actual sequence of work, in the order the crew performed it.
1. Site survey
Before anything is ordered, the engineer confirms three things on site: where the unit can be mounted, which route the ducting will take, and exactly where each nozzle needs to point. The route has to clear the exhaust hood and any existing services — water, gas and electrical — which is why this step is done on foot rather than from a drawing.
2. Brackets and unit
The unit goes onto vibration-damping brackets, levelled and checked for rigidity. A kitchen air conditioner runs for long shifts at high load; a bracket that is merely "tight enough" will transmit vibration into the ceiling within a season.
3. Duct installation
Stainless-steel insulated ducting is run tight to the ceiling, with additional fixings at every bend. The run stays out of the working envelope, so no counter or aisle space is lost.
4. Nozzles and commissioning
Adjustable jet nozzles are fitted and the system is started. Each nozzle is then aimed at a specific station on site — the angle is set with the cook standing at the range, not estimated on paper.
What the details are for
- Bracket spacing follows the load rating of the duct, so the run does not sag or deform over years of use.
- Nozzle angle is set on site — the air has to reach the person and must not disturb the burner flame.
- Work area cleared the same day, so the restaurant opens as normal the next morning.
Why we publish the process
Installation quality decides whether a kitchen air conditioner still performs in year five. Showing the sequence — survey, brackets, duct, commissioning — lets a customer compare what they are being offered rather than just comparing unit prices.
In Shanghai and the surrounding region we offer an on-site survey at no charge; for overseas projects we can survey by video and quote remotely. Get in touch to arrange one.
