The maternity unit of St Mary’s hospital is the centre for all high-risk maternity care in East Dorset. Its building services have been upgraded with Daikin heat-recovery VRV equipment installed by Cool Tec Services of Wareham while the special-care unit remained fully operational with babies in incubators.
Four wall-mounted fan-coil units with cooling/heating capacities of 7.1/8.0 kW have been installed in the neonatal intensive-care unit on the first floor, with further units in the two operating theatres on the ground floor, high-dependency unit and delivery room. They are served by a 14 hp outdoor unit against an outside wall at ground level.
The control system balances heating and cooling loads and enables compressors to draw 40 to 45% less power than the norm.
