Hello people. I was wondering if anyone could help me out. I'm new to this area of refrigeration and i need help with a question. It's about the " net refrigerating effect" of refrigerants. The question is should a refrigerant have a high or low net refrigerating effect. I know that the net refrigerating effect is the amount of heat absorbed by each kg of refrigerant in the refrigerating coils as it evaporates from a liquid to a vapor. What should i be looking at to decide what my answer will be.I need to be steered in the right direction. Thks.
