An open drive condensing unit has the following factory delivered options. Compressor maximum speed 550 rpm Compressor pulley size 600mm • Factory supplied motor pulley size 200mm • Motor speed rating 1400 rpm Pre-commissioning tests suggest that the suction pressure is too high, the system capacity is below requirement, and the compressor speed needs to be increased. Assuming that the motor has an adequate power rating to drive the compressor to its maximum speed, what size motor pulley would be required to increase the compressor speed by an additional 10%? Áll calculations can be rounded to the nearest unit of 10. All calculations are to be shown.arrow_forward
