Unexplained efficiency
My refrigerator seems to get more efficient the longer I run it. Am I missing something?
- I'm a newbie to refrigeration.
- The system is installed on a boat.
- The system is 22 years old.
- The condenser is cooled by circulating sea water.
- The system has a eutectic tank.
- 5 seconds after startup, watt meter indicates 1540 W.
- Over the next 60 minutes, the power consumption decreases by about 15 watts every minute.
- After an hour the consumption stabilizes at about 640 watts.
- The thermostat is set at maximum and I do not hear the compressor cycling on an off.
Can anyone offer an explanation as to why this system seems to run with less power the longer it runs?
