MECHANICAL HEAT RECOVERY SYSTEM
Used in the 'big buildings' around campus including Portland Square, Davy and the Charles Seale-Hayne Library.
- A heat exchanger is used to extract energy from circulated air. This energy is used to heat incoming fresh air which is then circulated around the building.
- Before a room becomes stuffy, the BMS will tell the heat recovery system not to re-circulate air, but bring in clean fresh air which can be heated to the desired temperature.
Used in the 'big buildings' around campus including Davy, Fitzroy, Babbage and Smeaton.
- Electric motors are used to run heating, ventilation and air conditioning systems and tend to be sized for peak demand meaning for most of the time they operate ineffectively.
- Retro fitting inverter controls to fans, means the output can match demand accurately. This is done by reducing the speed of the motor. If you reduce the motor by 20% it will reduce 50% of the operating cost and carbon emissions.
