were installed with a complete BMS system. These systems combine to provide around 300kW of heating and cooling and an ideal system for Christchurch conditions. The Aquanex MWH900 heat pump water heater, including a programmable control system, pre-heats the mixed return air/fresh air to achieve 10°C on temperature to the three 70kW rooftop package units. The MWH900 was applied to the system design for its reliability to maintain a supply water temperature of 40°C-55°C utilising an inverter compressor range of 13.3kW-91.9kW.
