Image recognition method for frost sensing applications

Frost formation in the heat exchangers of refrigeration systems is a well-documented phenomenon. This frost accumulation creates thermally insulating barrier that can restrict, or even block, airflow between fins, resulting decreased efficiency and degradation food products. Several methods detection defrosting have been developed, although there not an efficient mainstream method to measure control formation. In previous works, results small low-cost resistive sensor for were shown be promising. paper extends research using computer vision compare this with formed on exchanger, allowing better study sensor. allowed trace plot curve detected values.
