Research on Carbon Footprint Evaluation of Heat Recovery Ventilators for Outdoor Air Handling based on Life Cycle Assessment
A life cycle assessment methodology and SimaPro software are used to evaluate the carbon footprint of a typical heat recovery ventilators for outdoor air handling at the production stage.The results of the evaluation show that:For producing one group of heat recovery fresh air unit,the production of raw and auxiliary materials is the main process unit of greenhouse gas(GHG)emissions,accounting for 96.23%of the carbon footprint,while the carbon footprint from the production process is nearly 0.46%of the total,among which the cold-rolled plate used in the unit box in the production of raw and auxiliary materials has the highest contribution to the carbon footprint,reaching 52.46%.It can be seen that,under the premise of meeting the product performance,reducing the use of cold-rolled plates and other raw materials with high carbon footprints,and finding alternative products are the feasible way to promote carbon emission reduction in the heat recovery outdoor air unit products.
