Americold compressor from dehumidifier?

[Derek]

I've got an Americold compressor I've salvaged from my father's old dehumidifier he gave to me. The information about the compressor is in the pictures below for identification, etc. I can't find anything concerning Americold compressors online -- looks to me like the company went belly-up and didn't leave a history behind them.

The dehumidifier has a sticker on it that says it runs 6.25 ounces of R22, and the system is 7.3 amps. It also states 40 pints/24 hours for "dehumidification." It is designed for 400 psi high and 150 low. Anyways here are the pics!

I also need help identifying this oil. I'm going to be charging this new phase system with propane but I'd like to keep the original type of oil unless it's too expensive. Here's a pic of the color/amt of oil ... ruler to show scale (amount).

Thanks for your help!

R22 is R12 replacement right? R12 uses mineral oil only, so I'd guess that the oil is mineral oil. Propane carries both mineral and polyester though, so it wouldn't matter if you choose to replace it with the cheaper one. You should still change the oil though, you want to reduce contaminants as they lower performance and life span of the compressor.

mineral is cheaper

[Derek]

That sounds great (and cheap!). What do you guys think of the compressor? How many hp would you estimate it at? Will it be good enough?

Sorry for the newbness, but is the mineral oil used the same mineral oil you can buy @ a drugstore?

I'm gonna "Guess" 1/5hp :)

im suprised it uses r22. it looks like a matsh?? compressor

[wdrzal]

amps X volts = watts
6.90 fla(full load amps) X115 volts = 793.5 watts

1 hp = 746 watts

793.5 divided by 746 = 1.06 hp

info is on the tag

Sorry, this is off topic but I have this compressor:

1424 90B16 CAJ4452A R12 220V 50Hz 3.5A ld 20A
227 09311
L'Unite Hermetique S.A Tecumseh

So if: amps X volts = watts

then: 3.5a x 220v = 770watt

1hp = 746w
770/746 = 1.032hp

wdrzal is that correct? What does "ld 20A" stand for?

[wdrzal]

your math is correct...... here a LRA (locked rotor amps) is given , that is the maxium amps the motor can draw under any circumstance(locked rotor).

not sure about the Ld 20A. check manufacture's nomenclature to see if Ld 20a is similiar to LRA 20 amps.

Id is the current through the windings when the compressor starts.

That compressor is NOT a 1Hp compressor at the very most its a 1/3hp. 1hp compressors have much higher run and start amps than that at least double. I have a dehumidifier thats about the same size as his and its max amps is 6.9, i looked up the model # and its a 1/3hp 4100Btu compressor.

I don't think that method works for finding out the hp rating of a compressor wdrzal the reason being is i tried it myself on one of my compressors ,heres what i did my cascade system uses 2 1hp rotarys which can draw 10.5 amps EACH so if i took 10.5 x 115 i get 1207.5watts divide by 746 and i get 1.61Hp which is wrong.

[wdrzal]

Keep in mind the actual hp a motor puts out is the input wattage less effeicency losses of the motor. So in reality a motor with 746 watt input will not produce a output of 1 hp, it will be less.Also the hp of a motor in not static it is dependent on the load applied. motors are rated at their FLA (full load amps) which may be higher than the RLA (running load amps) usually the 2 are close togeather or even the same.

overcharging a compressor can give you a higher amp draw, thus a higher hp, but a motor in this state is overloaded and its life will be shortened.

i have an old compressor in an old a/c, idk if its any good. its huge tho.

115v 12amps
