Project Description:
The purpose of this project is to research the feasibility of developing a low cost air-to-air heat exchanger for use in residential and small commercial buildings capable of 50% or greater efficiency. Prototypes will be fabricated and tested.
Proposed Outcomes:
· Two or more full scale prototype air-to-air-heat exchanges.
· Hardware connection designs for conventional HVAC equipment.
· Feasibility assessment based on prototype performance testing.
Anticipated Benefits:
· Potential energy savings of 825 GWh/yr in California assuming only 10% and 1% market penetration in the residential and commercial building sector respectively.
· Reduce the installed cost of air-to-air heat exchangers by up to 90%.
· Improve the indoor air quality in modern airtight residential housing by providing a cost effective device for conditioning outside ventilation air.
