Fan coil units
Centralised factory control
The Ability Projects facility plant room and air source heat pump (inset) W
hen Ability Projects, a manufacturer of fan coil products, built a new purpose-built facility in 2016, it provided the perfect opportunity not only to showcase its own fan coil units (FCUs), but to demonstrate
the product’s potential for seamless integration with renewable heating technologies too. Ability Projects incorporated a suite of offices in its new factory facility that
would require zoned control of heating and cooling for complete control and comfort. Working closely with Dimplex’s in-house heating design team, the manufacturer developed a centralised control solution, incorporating a Dimplex air source heat pump and solar PV technology. Offering heating and cooling without any refrigerant pipes passing around the building, the system also includes heat recovery via the use of reversible air source heat pumps, which enables Ability Projects to use waste heat from cooling for hot water production. Peter Lowther, managing director of Ability Projects, said: “This was an opportunity to create a large scale heating and cooling system, which leverages the latest technology to ensure it is easy to control, highly efficient and cost effective – despite its complexity. “We were able to work closely with Dimplex’s own engineers which
recommended the air source heat pumps. They looked at the zoned control we needed, specified and then delivered a robust response that consisted of our FCUs, the PV system we had selected and their heat pumps. The system has worked extremely well, ensuring a comfortable working environment and, together with a performance review which has helped to refine the system, it has really delivered beyond initial expectations.”
Design excellence
Dimplex’s in-house heating design service was critical to the specification, calculating the total heating and cooling loads and zoning the system based on the office floor plan layout. Tasked with ensuring temperature control in individual zones, Dimplex specified a four pipe heating and cooling system, with two Dimplex LAS12TUR+ reversible air source heat pumps and two Dimplex 500 litre cold and hot buffer tanks. Ability Projects’ NR35 FCUs were selected to provide low noise, with low velocity grilles to maximise system performance and comfort for occupants. The FCU controls ensure the air temperature which is discharged above the occupants is maintained within strict temperature bands. Dimplex’s technical experts commissioned the system, before completing a handover that included user training for staff at the new Ability Projects facility.
