Balanced Ambient Calorimeters
Climatic Testing Systems, Inc. (CTS) Balanced Ambient Calorimeters are designed in accordance with ASHRAE Standard 16 and are used by air conditioner manufacturers to determine the rated capacity of window and split units. These systems can be supplied as calibrated room type or full balanced ambient with a conditioned annular space around the test room. Room temperature and humidity conditions are precisely and accurately controlled. All power inputs to the inner rooms and the test unit are measured and balanced. The calorimeters are provided with a fully automatic, computerized data acquisition and control system.
