Context

As part of a drive to improve the school environment, Whitmore High School in Harrow wanted to install effective air conditioning in its sports hall and canteen.

Prihoda were partners in the design of the diffusers and the air patterns in the installation of an industry-leading air conditioning system.

Challenges

Sports hall air conditioning and ventilation present a number of different challenges, most often because of the required high rate of air exchange. In venues with seating, as at Whitmore High School, the needs of spectators must be considered in tandem with those of the participants, teams, and referees. Temperature and humidity levels were also key concerns for the school. The school excels in badminton and, for this sport in particular, very low air velocity is required in the court area.

For the canteen area, the school wanted a steady and draught free delivery of air across a large area for the comfort of students, staff, and visitors.

Project details

A carefully-planned diffuser solution was designed which paid specific attention paid to air patterns in each area.

Sports Hall

One central diffuser entrained and mixed room air and moved this towards the walls. At that point, two diffusers, one for each wall, then delivered supply air to the required lower level. At the same time, it moved significant volumes of ambient air to mix and become part of the overall pattern of air. The sports hall now benefits for high air volume circulation and movements at the same time as providing much lower velocity for the badminton courts.

Canteen

Prihoda's premium polyester material was untilised with a view to create 4 half-round diffusers. Those diffusers were placed between ceiling rows in a lay-in-grid pattern. Colours chosen for the material were carefully matched to the colours used across the canteen for aesthetic consistency. Inductive air patterns were created through a mixture of duct-circumference laser-cut perforations laid out in blocks and tiny micro-perforations. Both velocity and air flows were mapped prior to installation using Prihoda’s predictive software.

For both the sports hall and the canteen, Prihoda’s fabric ducting solution was used. Fabric ducting controls the delivery of air in a more controllable and cost-efficient way than traditional ducting. It’s easy to clean and the way its manufactured means that there is no rapid dust build-up when in use. More and more end clients and specifiers are selecting fabric ducting for their projects because of its energy efficiency, its ability to deliver a uniform distribution of air, and its much quicker installation time.

Comment

"The Sports Hall was very high and required for badminton games, creating a long throw but low velocity design – a difficult situation with multiple air densities at different supply conditions. The canteen ventilation system needed to heat a large space, delivering air over a wide area without draughts" Paul Russon, Prihoda’s project lead
