This laboratory acquires cold capability/heat capability of air conditioners by measuring precise energy measurement of inlet and departed testing separator under the stable environmental temperature and humidity condition.

To achieve the test requirement, outside of the under-test separator added two sets of suit to maintain the same temperature and humidity with separator ambient and obtain heat equation from inside to outside, avoiding heat leakage of the laboratory.

Under above conditions, the cold or heat capability of under-test units in the separator by period is equal to the increased or disappeared heat volume in our wanted stable ambient and to create a dynamic heat equation state with high precision measurement.

This kind of calorimeters commonly used for benchmark laboratory. According to revert veritably at work environment of room air conditioners those without air path, it can reflect more accurately the capability of under-test units and energy wastage. This is the unparallel test method from other methods.
