Sub-Zero transforms utilitarian cold storage into top-of-the-line energy-efficient performance and elegant aesthetics. The Sub-Zero team uses simulation in designing compartment microclimates within the refrigerator so that every item in the fridge can be stored under optimal conditions. With Simcenter Amesim Sub-Zero was able to explore designs and test out various scenarios faster, and the extensively customized closed refrigerant loop library Maya HTT developed for Sub-Zero helped maximize efficiency.
