pressure release duration in refrigerator
Dear All,
I would like to put my own control logic on top of the existing one to control the domestic refrigerator.
Q1:
Does anyone know how long it will approximately take for a standard domestic refrigerator to release the pressure of the compressor, after the refrigerator is switched off?
i.e. it is safe to switch on the refrigerator again.
Q2:
the similar question, how long does it normally take to build up the pressure difference in compressor to make the refrigerator start cooling?
Thank you very much.

Q1, hard to say exactly but relate your restarting time to that specified by the manufacturer. There is a limit to the number of times a compressor should be started within a set time period.
Q2, about 10 seconds.Brian - Newton Abbot, Devon, UK

Re: pressure release duration in refrigerator
usualy for a cap tube system I'd wager absalute minimum time delay befor restart would be 15 minutes with a good safety factor.
but thats a educated guestimate based on personal experiance with small domestic fridges.
