fridge cycle logger
Hello all,
I'd like to know how efficient my fridge is. To do this, I need to have a record of the on/off cycling that the fridge does: I need to know how frequently it cycles and how long it stays on for. Does anyone know if this gizmo exists? (in the UK) If not, how would I go about making one?
Thanks, mm
Do you need to know the raw data in engineering terms for an experiment or do you just want to gauge if it is time to purchase a new fridge? This might give you an idea http://www.energystar.gov/index.cfm?fuseaction=refrig.calculator if you convert from metric as here across the pond, new major appliances must be sold with an efficiency rating. Setting up thermal probes or monitoring the motor starts may be cumbersome. I do have a "kill-a-watt" meter that does plug inline with the power cord to record the energy usage but then you would need to factor in ambient temps and number of times the fridge is opened, closed, etc.........
