Refrigerator temp

[tjandoverguy]

My refrigerator is 20 years old water cooled the condenser is 174degrees is this too hot

[StuM]

Fahrenheit or Celsius?

[tjandoverguy]

I put the heat gun on it body temp 96.8????

[Sailmonkey]

Is there something wrong with the refrigerator? The doesn’t seem odd to me

Am I the only one having difficulty following this thread???

Little things like punctuation and capitalisation were invented for a reason. They aid comprehension of the written word.



If people can't be bother to use them, they can hardly expect others to put a great deal of effort into responding.

Is the inside of the refrigeration OK?

BTW - as a 410 owner I'm amazed anyone still has one of those water cooled systems working. They are the #1 complaint by owners.

If you are measuring the refrigerant line temperature coming out of condenser after cooled by water 174 degrees it is too hot. Adequate preferred liquid refrigerant line temperature on its way to evaporator is around 115 degrees F or less.

Is 174 degrees too hot for the condenser

To reiterate what Richard is asking. Where on the condenser are you measuring this temperature?

[tjandoverguy]

There is a black round thing 6 to 10 inches in dia that was up to 191 degrees
Seawater cooled this
It's not flowing the water it had
I replaced pump 893 04 &$250 worked for a week
It getting 12v to pump

Could he be talking about the compressor? He is measuring the heat of compression?

Sounds like you're not getting water flow. I suspect after 20 years your water cooled condenser is limed up. Or there's a blockage in the hose somewhere.

Running some diluted phosphoric acid through the water channels into a bucket might help clear it up. You should be able to blow through the condenser on the water side. Take your discharge line put it in a 5 gal. bucket and time how much water goes into the bucket, in one minute. For a typical 500 ish btuh you should be getting roughly 0.5 gpm out the hose.

Sailorchic has it. Sounds like there is a water flow or buildup problem in the cooling water circuit.

[redsky49]

Temperatures that high would surely result in shut down from compressor safeties, wouldn't it?


Condenser water flow (gpm volume) dependant on unit capacity, which has not been stated. Sailorchic - 0.5 gpm??? Are you saying 0.5 gpm per 500 btuh?
One ton of cooling equals 12 gpm??
