As shown the indoor refrigerator consumes more electricity
than the window refrigerator. This is despite
the fact that the inside temperatures of the indoor refrigerator is
consistently higher than the window refrigerator. For the purpose of comparison, this gives an enormous unfair
advantage to the indoor refrigerator.
Obviously the window refrigerator would have consumed far less
electricity if it had a thermostat to turn it OFF as soon as its inside
temperature reached 40 °F (the lowest temperature reached
by the indoor refrigerator after 2 hours).
Unlike the Avanti, the Haier's back has a regular external (visible)
heat exchanger.
Description of the Indoor Test (left column): On 3/21/06 from 8:54 AM to 11:54 AM (3
hours), I ran the test for 3 hours indoors and recorded the data
collected by the "Watts Up Pro" power analyzer instrument in the
above spreadsheet. I also recorded the
temperature inside the refrigerator every 2 minutes for the first two
hours. The inside and outside
temperatures of the refrigerator at the beginning of the test were 70 °F. Initially, the motor/compressor was on for
the first 11 minutes and then was OFF for 5 minutes. On average the compressor was alternatively
ON for 3 minutes and was OFF for 9 minutes. For details, see the left side of the above
spreadsheet.
Description of the Window Test (3 right columns):
Outdoor
Temperature: 34 °F
On 3/18/06 from 10:23 PM to 1:20 AM (3 hours), I attached
the refrigerator to the window and recorded the data collected by the
"Watts Up Pro" instrument in the above spreadsheet. I also recorded the temperature inside the
refrigerator every 2 minutes for the first two hours. Initially, the inside temperatures of the refrigerator was 70 °F and the
outdoor temperature was 34 °F.
The motor/compressor was ON for the first 8 minutes and then was
OFF for 6 minutes. On average the compressor
was alternatively ON for 3 minutes and was OFF for 16
minutes.
Outdoor
Temperature: 52 °F
On 3/24/06 from 12:57 PM to 3:57 PM (3 hours), I attached
the refrigerator to the window and recorded the data collected by the
"Watts Up Pro" instrument in the above spreadsheet. I also recorded the temperature inside the
refrigerator every 2 minutes for more than two hours. Initially, the inside temperatures of the refrigerator was 70 °F and the
outdoor temperature was 52 °F.
The motor/compressor was ON for the first 9 minutes and then was
OFF for 5 minutes. On average the compressor
was alternatively ON for 3 minutes and was OFF for 12
minutes.
Outdoor
Temperature: 63°F
On 3/30/06 from 11:58 AM to 2:58 PM (3 hours), I attached
the refrigerator to the window and recorded the data collected by the
"Watts Up Pro" instrument in the above spreadsheet. I also recorded the temperature inside the
refrigerator every 2 minutes for more than two hours. Initially, the inside temperatures of the refrigerator was 70 °F and the
outdoor temperature was 63 °F.
The motor/compressor was ON for the first 9 minutes and then was
OFF for 5 minutes. On average the compressor
was alternatively ON for 3 minutes and was OFF for 9
minutes.
