Design, testing and optimization of a new energy exchanger

More than 30% of the energy used in Canada is directed to control the indoor comfort

conditions and to provide an adequate supply of conditioned ventilation air for buildings. For

commercial buildings, 20 to 50% of the energy used may be used to condition outdoor

ventilation supply air to maintain comfort conditions. Using commercially available energy

wheels, heat and moisture exchange between the supply ventilation air and the exhaust air

can reclaim 80% of the waste energy in the exhaust air; however, it may be not cost effective

for retrofitting existing buildings because the supply and exhaust air ducts are not side-byside.

The purpose of this project is to design, test and optimize a new run-around,

membrane energy exchanger (RAMEE) system for buildings that will transfer heat and

moisture between remote supply and exhaust ducts. This novel RAMEE system is expected

to be cost effective in both new and retrofit applications.
