Window Air Conditioner Test Rig
The window AC is fixed in a rigid angle frame, with its cover cut half open to reveal the internal parts of the AC. The required pressure and temperature tapings are drawn for measurement of pressures and temperatures at salient points. With the help of manometer, velocity of air and consequently the flow rate of air can be determined. A sling psychrometer is provided for measurement of inlet and outlet Dry-bulb & wet bulb temperature. The Window AC test rig is designed and manufactured such that the students can understand construction and working of a window type air conditioner and conduct the trial on it to evaluate performance of the same. Energy meter is provided for recording compressor energy consumption.
