Main Requirements of Project
In 2007, the BCIT decided to retrofit a test facility mechanical system to geo-exchange from boiler/packaged air conditioner system. The building is called the AFRESH Home and it is located on their Burnaby Campus. In addition to providing a demonstration system for use by students, the BCIT also trained several students by involving them in the construction of the system. The piping is nearing completion and BCIT personnel will be implementing the DDC package next.
In parallel to the geo-exchange retrofit project (and in the same building), a demonstration fuel cell project was implemented by the BCIT and BC Hydro – the local electrical utility. The geo-exchange system is configured in a way to enable “waste” thermal energy from the fuel cell to be injected into the heating system thermal storage tank or into the ground for seasonal thermal energy storage while the insulated indoor tank is up to temperature and the fuel cell is running.
Altum Engineering, Ltd. (Altum) designed the system for BCIT and it includes several unique features.
The following modes of operation were made possible in a simple, reliable and cost-effective manner using the Innotech Maxim II controller:
