Ventilation & Controlled Environments
Goals:
- Maintain 17–25°C with natural ventilation.
- Waste heat from controlled environments is re-used in the building.
- Maximise energy-efficiency
ECO-AIR technology
Air heated by machinery running fume cupboards and refrigeration
/ freezing equipment, and air-conditioning and dehumidifying systems
is ventilated to the outside through the ECO-AIR units on the roof.
The units contain innovative heat exchange technology for energy-efficient
heating /cooling of the replacement air that is drawn in through
the ECO-AIR units.
Air-conditioning
Some specialist areas require cool conditions (e.g., 18°C,
45% relative humidity for the collections). Reverse heat-cycle
pumps with variable refrigerant volume (VRV) allow flexible, energy-efficient
air conditioning.
Chilled-water systems provide backup.
Freezer/chiller rooms
A centralised environmentally friendly R 404A refrigerant system
with individual control at each evaporator maximises the energy-efficiency.
