The Refrigeration Test Chamber's primary purpose is to evaluate the performance of commercial and residential refrigerators, freezers, wine chillers, ice makers, and other refrigeration products. It is a temperature- and humidity-controlled environmental room that provides controlled environmental conditions.
The Test Chamber is designed to maintain a single point operating condition and is able to maintain dry bulb temperatures in the range of 40°F to 120°F and humidity conditions in the range of 30% to 95%. It has the capability of testing four refrigeration units simultaneously at a single operating condition.
