This equipment is used for measuring cooling capacity, flow rate, driving torque of compressor, etc. The features of this equipment are that the compressor is connected to a speed change moter with a torque meter as an axis and that the wind velocity at the inlet of a condenser can be changed according to the number of revolutions of the compressor. The equipment developed recently excels in performance and durability, collecting occasionally such transient data as 10-mode running, rise characteristics, and so on.
