Hello.

Not too long ago, I saw the inside of a split unit which was around 12,000-20,000 BTU I think, and it was so thick compared to that of a window unit.

Is it me or are split unit...

Oh. I hope the compressors themselves haven't been affected as yet. The datasheet for the most expensive compressor which I am starting with says that it needs this oil:

SUNISO 4GSD 或同等品 ·480 ml
...

I'm glad to hear that the compressors should be fine. How does the ruined oil affect the compressors, though?

I guess I need to find an oil change tutorial somewhere.

They have been this way for months.

All of them still work.

I currently have a PVC gas hose attached to one of them with clamps, that should be fine.

I keep worrying that I have to try and get nitrogen but forget that I can suck out the air instead. :D

Ok. Is it a corrosion issue?

Hello.

If a compressor is not being used at the moment (one is R22 and the other R134a), can I simply just cover the ports with tape and put them away? Or is there more I should do?

Do I have...

If all the compressor needs is an oil replacement then I would do it because I really want to use this compressor to attain temperatures below freezing.

Any other opinions or details that might...

Hello.

My Embraco FGS 80HAW fridge compressor and LG LX67LAQG fridge compressor are both R-134a and they are each 1/4 HP. They both have two oil cooling tubes at the bottom.

Would I have to...

Hello.

Does anyone know if a new R22 rotary air conditioner compressor can be installed in an R-134a system? I have been seeing opposing views about this on the internet. Some say "probably",...

Oh. :( That is why I asked, I wasn't sure about that.

I wonder if it is 20 uF like the Embraco compressor which appears to be the same size.

Never mind, this argument isn't going anywhere and is only causing trouble.

"If you have 2 refrigerator compressors .... you might as well hang them on the wall and frame them , because its rare a...

I meant safely. I know that typical R22 air conditioner compressors cannot safely operate below freezing, and R22 compressors are usually designed to operate with R22 only, aren't they? Refrigerator...

Telling you that the two are different technologies is not trying to explain the difference to you, that is telling you that there is a difference.

Don't say "Not to be a jerk" if you are going...

10% +/- what?

The fact that it is piston powered is what makes it different from most air conditioner compressors, and yes, a pistons are very different from a rotary unit. The two are not the...

My Embraco is the F series: http://www.embraco.com/?tabid=190&idcat=9&idfam=19

No one knows of any guides that will explain the basics of refrigerator compressor installation?

t527ed: I won't...

Also, I need a guide that teaches me about household refrigerator compressors, anything that contains such a section. I am new to them. What I have learnt so far is about the air conditioning type,...

Hello.

Today I got two free refrigerator compressors from a store that said they were not working because they were damaged during installation. When I got home, I tested the motor coils and all...

I just attached my 5/16 inch tube to the compressor outlet to do a quick pressure buildup test and it built up and was hissing at the joint, plus the compressor started making a noise. When I...

It is not to replace a customer's parts. I would never do that. It is for myself. I don't have $12,000 to buy a new one anyway, that is far from feasible.

Hello.

I just called a local air conditioning and refrigeration store and asked them if they had any discarded refrigerator compressors, and they said that they have a damaged 1/6 HP and 1/3 HP...

Hello.

Can I use a refrigerant other than R22 to achieve lower temperatures? Maybe R134a?

I have an old compressor for evacuation, but I haven't gotten a cylinder for recovery yet. It is for multiple projects, but the aquarium is for the future, and i'm not sure about salt yet. I will...

Thank you. I appreciate it. :)

Hello.

I would like one of the 1/8 HP fridge compressors that is used for mini-fridges and water coolers, but they cost even more than the mini-fridges themselves, which are also too expensive....

Why would someone want to share sensitive information to anyone else at all over the internet? I would not bother with that, and I would not restrict all chiller discussions to the point where new...

Could you point me to an article which explains how to make these calculations?

I already bought 25 feet of stainless steel tubing which will be the plain tubing evaporator, and will get the 20...

Hello.

Can I safely construct a 12,000 BTU R22 water chiller using 25 feet of tubing for the evaporator and 20 feet for the condenser (45 feet combined)? (It is 5/16" tubing).

I am using a...

Oh, my apologies. Maybe I wasn't wearing my glasses.

The hose is to attach the refrigerant line to my 12,000 BTU compressor and enable flexibility.

The reason why I asked is because Chris said the thread was moved to AOP, even though I started it and I cannot access that section.

I don't quite understand what is happening here. Could someone...

I am not an AOP member so I can't go there.

Sorry, It was too long for me, so I only read some of it (not most). Plus i'm feeling ill at the moment.

I have mixed feelings about it.

In my opinion, I believe that it is appropriate for the...

lol. :D

Hello.

When I was in a local hardware store, I found a hose labeled LP Gas/Propane hose and it is to attach gas stoves to the gas line coming from outside and with flexibility. Since propane's...

Thank you. :)

Why is 45% silver necessary, though?

Thank you for the PDF. :)

Especially design.

Yes, the power supply frequency is 50 hz here in Jamaica.

Yes, the translation of that datasheet was awful. Reading it was difficult. :(

72 million BTU? That is must be industrial. You can't...

Hello.

I need a book that explains chillers. Does anyone know of any?

0 C (32 F).

Small compared to industrial units, but big for any house room.

I will add you on Youtube. :)

Ok, so it is inefficient to try to cool it to such a low temperature you mean?

12,000 BTU is not little.

Can at least 0 work then? I just want to know that I can safely at least freeze water then, but the lower that is possible, the better.

I guess we're not on the same page. Why would the compressor overheat if it was designed specifically for R22, and for reverse cycle air conditioners? If it is designed for reverse cycle air...

It is attached to this message.

I don't understand how the compressor could be R22, designed for reverse cycle operation if it can't handle winter cold temperatures...

I am trying to freeze water.

I'm sorry, I forgot to mention that the refrigerant is R22.

When you say SST, do you mean Suction Saturation Temperature?

Hello.

In the datasheet of my Toshiba 12,000 BTU PH215X2C-4FT1 rotary air conditioner compressor I don't see a minimum temperature that the evaporator can operate at without harming the...

Ok, I haven't been able to find 45% silver yet, but, until then, i'll have to use the ordinary alloy. :(

Thank you. You've been helpful. :)

Thank you. :)

I actually ordered the stainless steel tubing already, and it will be used to chill water.

I like the corrosion resistance of stainless steel tubing, and it was much cheaper than the copper on...
