Residential Case Study
Worcester House Case Study, Residential
Summary
- Renovating an existing residential property or adding an extension offers the opportunity to assess how the home is heated and cooled.
- More homeowners are considering the possibility of installing air conditioning.
- An Invisible.AC system provides a complete solution which can be cleverly designed and included at a later stage of the build project.
The Challenge
- How to incorporate an Invisible.AC Small Duct Induction Heating and Cooling system when the superstructure of the building was already complete.
- The homeowner added a 110 square metre extension to the existing building featuring an open plan living area and separate office.
- It had become clear that the building’s air tight construction and the solar gain from the roof lights and glazing would make the indoor environment uncomfortable.
- There was no way of accommodating main ducting between constructed ceiling joists or an air handler within the building envelope. An alternative approach was required.
- The solution needed to fully complement the extension’s stunning interior design and operate with minimal noise levels.
On-Site
- The most significant was where to position the main ducting, linking the air handler to the space saving flexible mini-ducts, without internal intrusion.
- The solution positions the main ductwork and air handler out of sight on the outside wall of the extension.
- Invisible.AC’s slimline refrigerant coil air handler are vertically mounted adjacent to the Air Source Heat Pump renewable energy source.
- The 10kW air handler is just 225 mm deep x 900 mm x 900 mm, supplying conditioned air through customised prefabricated 150 mm deep x 500mm high mineral wool fibreboard ducting sections.
- These are highly insulated for energy efficiency and with a special acoustic, noise reducing inner fabric.
- The joined sections reach up the outside wall. A T-joint extends the ductwork across the full width of the building, connecting to 28 branches of Invisible.AC flexible supply tubing. The ductwork incorporates two dampers to give individual room control.
- The electrical supply panel and controls have been encased within an easy access external weather resistant, fully insulated cedar wood finish cupboard.
The Benefits
- The contemporary, minimalist white interior design of the extension has been complemented by an ‘invisible’ system that adds to the ambience of the open plan extension.
- Discreet, white finish flush round room outlets have been positioned around the edges of the ceiling to provide optimum performance and even distribution of conditioned air.
- Pairs of outlets have been installed side by side in the skylight recesses to tackle solar heat gain at source and keep the interior temperature remains at the required level.
- Fast response times, extremely quiet operation and a temperature variation is no more than +-1º C floor to ceiling throughout the extension.
- With the zoning capability, two separate cooling zones have been created for the living and office areas and controlled with wall mounted Heatmiser Smart Thermostats..
Conclusions
- The overall design concept of the complete system required out of the box thinking from the Invisible.AC team.
Customer Says
"I am very pleased with Invisible.AC in terms of the performance of the system and the thought given to its design. It has enabled us to include air conditioning at a late stage of our building plans."
