Restaurant areas at the Eden Project in Cornwall required an air-conditioning system that would allow conditioned air to flow over hardworking staff in serving areas whilst not over-cooling spaces where people were eating. The client also wanted LED lights to be incorporated into the design.
Prihoda was chosen to supply and design a high-quality fabric ducting system.
Prihoda's approach was to create one installation of fabric ducting manufactured in such a way that it would distribute the two desired air patterns for the client.
For the seated/occupied area, large-diameter laser-cut perforations were located at the front of each duct so that the desired volume air at the correct velocity would be jetted into the occupied seating areas.
For serving staff, blocks of micro-perforations – essentially rows of laser-cut holes four tenths of a millimetre in diameter - were used. This provided high air volume but at a very low velocity delivering fresh and cool air directly into the service environment.
The client wanted LED lighting to be mounted inside the fabric ducting. The team had already supplied several material test swatches and Light Grey premium fabric ducting was selected because it allowed for the desired level of lighting. During production, an LED lighting strip attached to a strip of velcro was sewn into the ducting. The velcro strip was to be placed right along the entire length of the half round fabric ducts.
The rigid, flat, oval duct was converted to a client-specific half-round shape. This speeded up production time and also helped the installation contractor as this particular design was easier to install.
The polyester material used in Premium fabric is also anti-microbial, non-hygroscopic, and non-shrink. Given the placement of the fabric ducting within a food environment, it was important to provide cleanroom quality material (certified to ISO4 – Class 10 standards) with a specific quality guarantee that no fibrous materials from the ducting would enter the supply air system.
