Design and Manufacturing of High Performance, Reduced Charge Heat Exchangers

1. Overview: 2. Background: Heating, ventilation, air-conditioning, and refrigeration (HVAC&R) systems consume a significant portion of residential and commercial building energy. Reducing refrigerant charge to mitigate greenhouse gas emissions is a crucial objective. Traditional heat exchangers (HXs) using round tubes and fins have limitations in performance improvement and require further miniaturization to meet reduced refrigerant
