Airports are a perfect environment to utilise displacement ventilation due to their high ceilings and large quantities of people.
High level lighting loads which can cause a major increase to the room heat gains can be dramatically reduced and in certain instances the fresh air load requirements can be that of the supply air volume. Most airport projects require bespoke terminals to suit the requirements.
A design programme is then set up usually resulting in prototype terminals been manufactured and tested to ensure that the client is comfortable with not only the visual appearance but its technical capabilities.
Once all approved, the units are manufactured and supplied to the client, resulting in a successful displacement system, beneficial to everyone.
Comfort have over many years worked in conjunction with numerous architects and consulting engineers to provide bespoke displacement terminals for a number of high street retail customers.
As with most displacement terminal applications, most things can be achieved with a little thought as long as the surface areas required can be met.
The air in a displacement system is introduced at low level and at very low velocities, displacing pollutants to high level resulting in an enhancement in air quality producing a fresh comfortable living environment for everyone to enjoy.
Supply air temperatures of 18C to 19C also ensure greater free cooling periods for a displacement type system, resulting in energy savings of up to 50% over a more conventional design.
Numerous terminal designs have been devised, tested and manufactured to incorporate rails, mirrors, lighting, small power etc which are also essential for a client to market their products.
Benefits to everyone from the client to the customer, makes it an easy decision when designing a retail project to incorporate displacement ventilation.
Displacement type systems are well suited to many leisure facilities due to the high occupancy loads and heavy internal gains sometimes generated.
Usually contacted at the concept stages of projects, Comfort, design and manufacture bespoke displacement terminals to suit the specific project requirements needed, often to overcome the difficult task of conditioning the space without seeing the mechanical services.
Units are often concealed within walls, seating areas, bars etc to be non obtrusive to the public, while still performing to the projects requirements. Units can be manufactured to suit any finish, texture or colour with numerous over clad materials available to choose from.
With the low carbon emissions, energy savings and the enhancement in air quality being just a few of the key factors it comes with no surprise that many high profile projects in the leisure industry have been keen to use displacement ventilation.
Many Industrial projects are now utilising high level displacement ventilation. This is a great system in this sort of environment as it keeps the terminals off the floor to allow access to all parts of the floor areas, which in many cases is essential.
Not only does it give companies a great saving in their energy bills, but it also produces a much better air quality in the working environment, which is a major feature to have in an industrial work place.
The volumes required to condition these types of spaces compared to conventional systems operating in similar buildings can be dramatically reduced due to reductions in high level lighting loads and air being supplied at much higher temperatures.
The falling air flows are controlled by means of an internal nozzle system. This system ensures that the required large spread of air is achieved over the floor area.
New schools and academies across the country are another large sector benefiting from displacement ventilation.
Comfort has over the last few years seen a significant increase in these types of projects, resulting in many different types of terminals being manufactured and supplied to many UK projects.
From class rooms needing standard displacement terminals incorporated into walls to sports halls and auditoriums utilising high level nozzle ducts giving a great alternative to traditional supply air diffusers, especially when a visible installation is desired as a functional décor.
Due to the low noise generations from a displacement system, offices, TV studios and many more general projects are benefiting from utilising displacement ventilation.
