L&K Group led the construction of a new 1,000m² two-storey facility, and DD Cooling Ltd was selected to design and install a high-performance commercial air conditioning solution that could provide reliable climate control across this busy, multi-use building.
The Solution
After a detailed site assessment, DD Cooling delivered a tailored Mitsubishi Electric air conditioning system, known for its energy-efficient performance and suitability for large commercial environments. The system design prioritised indoor air quality, zoning flexibility, and minimal visual impact, with ceiling-mounted and wall-mounted units placed strategically throughout the premises.
Installed system components included:
- 3 × 25kW triple split ceiling-mounted systems
- 1 × 5kW single split ceiling cassette
- 1 × 2.5kW single split wall-mounted unit
These sustainable HVAC systems provide zoned, reliable climate control, helping create an ideal working environment for staff and a comfortable space for auction attendees.
The Outcome
The completed installation delivers consistent and efficient heating and cooling across both floors. DD Cooling’s commercial air conditioning solution enhances employee productivity and customer satisfaction, while aligning with the site’s sustainability objectives.
Benefits include:
- Zoned temperature control tailored to different operational areas
- Improved indoor air quality for staff and visitors
- Low-energy consumption supporting green building goals
This project reflects how Mitsubishi Electric air conditioning, when expertly specified and installed, delivers exceptional performance for large buildings.
