How many kW is a refrigerator?

Answer 1

This is a difficult question to answer its kind of like asking how much petrol a car uses- any car.

The factors that will make a difference include how full is it, how often it is opened, how hot the place is where it is and how efficient the fridge is and how low the temperature is set.

I can give you a ball park figure for a modern fridge freezer operated in the UK.

First of all most of the time it uses 0 watts of power.

Only when the pump is running or the door is opened (the light) does it use power. I ran a plugin meter on mine which showed

motor/pump running 100 watts door open 12 watts both motor and light on 112watts

The pump on mine was running for no more than 5 minutes an hour and with this being such a rough calculation we can ignore the light.

so 100 watts for 5minutes an hour

means it runs for 24 x5 minutes a day 120minutes or 2 hours

100 watts for 1 hour is 0.1kwh so per day 0.2kwh or 1kwh every 5 days.

365 days in a year divide by 5= 73 kwh per year approximately. It could be less than that.

now lets suppose it uses a 200 watt motor and runs for 10 minutes

that would be 292 Kwh a year 4x as much roughly £14 - £58 that's a reasonably worth while saving.

Your best saving is to adjust the thermostat to a setting which keeps your fridge as cold as needed and no more and leave some space at the back of the fridge so the air can circulate.

If your fridge pump is running more often than not its time to get a new fridge.

Answer 2

take amps x volts=watts
