Adler Barbour Refrigeration - Evaporator Clearance

I installed a new SCM into an 7 or 8 cu ft fridge. Using the large horizontal evaporator.

The fridge will (someday) be torn apart and rebuilt but till then I have only about 1/2" clearance on the sides of the evaporator.

How much will this limit the cooling capacity? What is the recommended side clearance?

THe bottom is free and clear. I had thought that I could put a fan if needed to draw air past the top and sides.

Regards, Ethan

Re: Adler Barbour Refrigeration - evaporator clearance

I can't recall, but I seem to remember the manual mentioning clearances in it. We installed ours with a cold plate and didn't have the spec'd clearance on the sides, but did on the bottom. It works well for us. I do think that because the unit can cool a 15 cu foot fridge, it would likely work. It might not be as efficient, and your fan could be a good idea, but it will keep your box cold. Try it without and see how it goes.

Re: Adler Barbour Refrigeration - Evaporator Clearance

Because you have the large evaporator and it is not up against box liner 1/2 inch is not going to stop natural air movement needed to transfer heat into refrigerant. What will happen if there is a little less heat transfer is an improvement in delta T temperature between evaporator freezing chamber and refrigeration section by lower freezing chamber temperature without lowering refrigerator section temp. I am assuming evaporator is mounted high in box, if not a 10 cfm fan in box running all the time will force warm air to bottom of box normalizing overall box temperatures.

You can take Richard’s advice to the bank.

See the Instructions ➥ http://www.raycotechnologies.org/adlerbarbour.pdf

“... Locate the evaporator vertically, as high as possible on any sidewall in the icebox. Template, standoffs (1”) and mounting screws (1-3/4”) are supplied ...”
