he wants to pull 6000 BTUs through something similar to that:

https://www.amazon.in/CentIoT%C2%AE-40x40x12mm-Waterblock-Radiator-heatsink/dp/B07RF6G3NT?th=1

you can't pull 2 x 3000 BTUs through a processor cooler. You want to freeze it or what? Use liquid nitrogen

something must be wrong with your dimensions. 54mm x 34mm = 2" x 1.5", what kind of evaporator is that? that will for sure not take two Secop SC15CLX.2-1, would be 6000BTUs = 2000W cooling power...

it took me more than one week on my Ender, however finally today morning it finished the job. I just brazed it in and it works!!!
:cheers:

it is used in refrigeration, hardly in AC.

I did.... and it was a hell. but the mechanism of action is different than refrigerants. It forms immediately H2SO3 acid in your lungs...

in my country when we run out of vacuum oil, we substitute it with coconut oil.

not if you run it in dry mode (takes a bit longer to cool down but once it is cool it keeps the humidity pretty consistently low). I have my complete office (600 sqft) run on a single SEER 38 unit...

there are mini splits that modulate down to 2000 btus.what's the problem? YOu want the fan off? Fan going on and off is actually far more annoying than a fan running at low speed, believe me.

in any case get an inverter unit. It will regulate itself between mix and max. Get the heat load to be in the middle of the unit's range (e.g. 4000-14000 btus unit if your load requires 9000 btus)

approved by me

ps is there a way to build a HFC disposal machine? sort of plasma flame or so?

HF made by HFC flames isn't fun either.

check whether indoor & outdoor unit are not mismatched. Sometimes they mess it up selling them

maybe you have slept the last 20 yers, but R22 was replaced by R410A, which is now being replaced by R32. And yeah the accident in my town was likely due to R22. However, since many places have been...

because they want to sell you something.

But better ask this question: why is a GWP 2050 gas replaced with one with GWP 670, while there are alternatives with GWP = 1 ... 4 ?

it accumulates on the floor. heavier than air

it was a 5 ton system - from the press. How it exactly happened I have no idea, I suppose it leaked into their bedroom. They did not wake up.

it is not end of world.... I will worry only if they are out of KFC in Kentucky

still you are not dying from taxes.

you see when the pressure goes down to nearly 0 on the suction line, that the refrigerant has been "sucked in"

just rated VA multiplied with 208/240 factor.

I bet on it: you can take a regular dual voltage 240V/208V transformer (with 3 primary terminals), for whatever secondary voltage and use the primary only as autotransformer. Both hots go to the...

just look here:

https://en.wikipedia.org/wiki/List_of_refrigerants

IDLH for R32 77g/m3, IDLH for R410A 420 g/m3. quite a difference. there may be enough charge in a split unit to contaminate
a...

so you just mean conventional transformer, not a buck converter (these also exist)

for me: buck and boost = device that rectifies the AC to DC, then boosts it via high frequency (small) transformer to higher (or lower) voltage, then rectifies it again and feeds an inverter that...

last year 3 people died sleeping from refrigerant leak in my town

reason: reliability. electronic stuff doesn't last today. See it like this: you can get a buck transformer maybe for $100, a conventional transformer for the same power maybe $300. But the first one...

if no charge was added due to extra long line set, then it should hold it all

same thing. It is a transformer with just one winding and a lower tap

you can probably get a 240/208 to 24V or so transformer and use the primary side as autotransformer

it will be issue with system leaks

apparently the difference is an order of magnitude between the two. New systems will be equipped with R32....

I would be more worried if he found dead in the prison hanging on his shoelace

weigh it before install and make your notices. weigh it when refrigerant is missing (clean the coils etc to not weigh any bugs). And then you know how much is missing.

the price will be proportional to the damage it is doing to the environment. Extensive damage happens due to ODP>0

no. I weigh the complete outdoor unit

who buys at Wallmart...

well, caps loose the capacity when going bad, not gain it. They put it there in place, who knows why? maybe it must be 50uF so they just put what did read right?

you don't charge by psi...

better just install a down transformer. There are 240 to 230 transformers. Just reducing it a little bit will put you on the safe side.

earlier in the last century products were made to last to satisfy the customer. Now products are made to fail just after the warranty period, so the customer can buy a more modern product and be even...

yeah I should have inspected a "good one" LOL. I just wanted to get this mower going though. I promise next time it fails I will clean up all connections and make pictures.

unlikely. it was a fine stranded wire coming from the clamp block and somehow tied to 5 Al winding wires. I do not see how you would spot weld that. Found no remnants of a ferrule either

what worries me more: there was apparently no crimp connection between the original copper tinned cable and the winding wires. I have no clue what they did, it just came out in pieces. Might have...

so, it is running again :o sort of weekend repair, I had no proper material to do it well, so I took an bare ferrule, crimped the Al wires on one side and soldered copper wire on the other side. Lets...

what is even worse: seems to be AL wire, damn. How do I crimp it to the Cu wire? and I stupid was thinking I will just solder it

how do I best clear that winding wire coating? sandpaper?

found the cause, damn...

the burned jacket was not visible from outside, it was on the inside between two jackets

nah. it is not a stepper
