Refrigeration power calculation
WebIf the wattage is not listed on the appliance, you can still estimate it by finding the electrical current draw (in amperes) and multiplying that by the voltage used by the appliance. Most appliances in the United States use 120 volts. Larger appliances, such as clothes dryers and electric cooktops, use 240 volts. WebMay 12, 2024 · To to calculate the real hp, we need to multiply the kW by the motor efficiency and then convert to hp. As an example, a 100hp motor and 95% efficiency would need input kW of 78.5kW. The motor efficiency rating is line 7 in the CAGI data sheets. All of those compressors are “100 hp” compressors.
