Case Study - Air Conditioning
Wyder Construction
When Wyder Construction approached JJ Ventilation to provide air conditioning, ventilation and an air flow management system for a new building designed for use as a private cosmetic surgery, we were eager to take up the challenge.
Problem
In order for the building to gain the appropriate medical accreditation, specific design criteria had to be met. Each of the treatment rooms and the sluice room required a negative air pressurisation as well as comfort cooling and heating. The negative pressure was required to prevent bacteria cross-over between the rooms and also to control possible odours which are produced with laser treatments. In addition, we also had to handle all the extraction and ventilation requirements for the water closets and personnel areas and needed to comply with building regulations.
Solution
To meet the initial design requirement of comfort cooling to all treatment rooms, recovery rooms, reception and administration areas, we installed a total of fifteen cassette type and wall mounted Fujitsu heat pump air conditioning units.
These units cater for all summer cooling and winter heating requirements. To achieve an acceptable balance between overall cost and external aesthetics, multi-split type systems were used to limit the external condensing units to a total of six.
For the air flow management and building regulation ventilation requirements, JJ Ventilation supplied a further seventeen Vent-Axia fans and control systems, most of which were installed to provide room-specific extraction to create the necessary negative air pressures.
We also installed two ventilation systems utilising Vent-Axia equipment and air-to-air heat recovery to achieve a constant year-round fresh air supply within the high traffic areas.
Key Requirements
- Room specific comfort cooling and heating.
- Air-to-air heat recovery to meet stringent building regulations.
- Negative pressurisation and air flow management.
- Water closet extraction systems.
- Cost effective solution without compromising external aesthetics.
