The compressor swept volume cfm required is calculated: 1000 x 2.53 x 1⁄ 0.78 = 3244 cfm Compressor Power A refrigeration compressor’s power requirement expressed in terms of brake horsepower divina majestadWebThe power consumption of refrigerators is 400-1,000 kWh per year (this applies to models in the 21-25 cubic-foot range). The average energy usage of modern refrigerators is 400-600 kWh per year. This translates to 33 kWh-50 kWh per month, or an average wattage of 46 to 69 Watts (this equates to an average hourly power consumption of 46 to 69 Wh). bebelus sinonimWebYou can calculate kilowatts by multiplying amps and volts and dividing by 1000. From there, you can calculate kilowatts by multiplying amps and volts and dividing by 1000. Kilowatts = (Amps x Volts) / 1000 Refrigerators cycle on and off depending on their inside temperature, so their electricity usage varies day to day. bebelus se zbate la san
