Moving airconditioner compressers

[carlyai]

SWMBO's extensions, mean I have to move the 3 compressers outside, they were outside, now when the extensions are finished they will be inside.

So I have to move the compressors power feed and water drain about 3m.

1.

Now the aircon guy said we can jack up a channel in the cement and feed the power and water pipes in this channel. So the pipes would come down the wall as before, go through the channel in the cement (which is being tiled over) to the compressor and condensation water outlet.

2.

The aircon guy also says that sometimes critters get in the water pipe and block it up (even though they haven't so far). So what he suggests is we take the power and water pipe up the top, through the ceiling and install a sump and small pump ...then run it all through the ceiling outside to the compressor.

I've never heard of this, and I feel a sump and pump is probably going to cause more problems than a gravity feed water line buried under the cement and tile.

Which way do u think, or is there another way?

SWMBO doesn't want the compressors left where they were.

Got some pics

Two of the aircon feeds to the removed compressors.

How the compressors were connected.

Install a sump and pump and go through the ceiling?

You can see in the painted area where the compressors used to be and moving to the outside new area (not concreted ot tiled yet).

Sorry for the pics upside down. Still havent sorted out that prob. As look fine when i send them. [emoji21]

I have only seen condensate pumps fitted to large industrial ammonia evaporator trays, however they work ok.

[Anythingleft?]

Put the lines under the concrete and whenever the units are serviced just have the condensate lines blown through with compressed air to keep them clear (they will have a compressor for cleaning the screens and filters anyway) seems like an over complication to have extra pumps and additional electrics installed for this

Thanks again.

Yeah that's what I thought, and I (long time ago), used to look after some real-time water cooled computers, and the main problem was the sump drain for the evaporation kept on clogging up and the sump water overflowing.

I could just imagine that again but with 3 sumps and 3 pumps.....just look in for trouble.

Thanks again.[emoji1]

'the best made plans.....' so I've redecided to go with 3 sumps and 3 pumps. Maybe not too bad after all.

No one wanted the aircon ducting going down the walls, except me, I didn't care, so putting them in the ceiling would hide them, so may as well be convinced to run the drains thru sump pumps in the ceilings as well.

I only have one vote, SWMBO has 10 votes and the Thai tradies the other 10 votes ....so I lost.

Googled it and there are some neat little pumps and sumps around, so shouldn't be too bad. [emoji1]

Update: Nearly finished moving the aircons outside.

Installed the little pumps for the drain water and put the pipes in the ceiling.

Should end up with a reasonable installation.



The pump.



Relocating the power etc to the veranda ceiling.



Relocated aircons outside.

Have included the pump and specs.





B 1250 or round about.

all ceiling units have a tiny pump to get rid of the condensate. i shared Carlyai's concerns but have never heard of failures. but i would feel uncomfortable having them in rooms with gypsum board ceilings and it tool me quite some time to decide "ceiling or wall". finally i opted for a ceiling unit in the pool area (our alternate living room) which has a cement board ceiling.

That looks nice Naam.

The prob as I saw it the condensation water had to go up from the aircon drain, and I didn't want it dripping in the rooms if there was a problem.

In hindsight, ceiling units would have been better, but (as I wrongly thought), due to my super house design, I wouldn't need aircon....now we've got 3. Might end up with 4.[emoji53]

Start of blowing a gale here, so when I get the pool in, will need to put it inside as well....eventually.

Finally found where I can get the 8" cement blocks and found an interesting site in Banggers for Nano blocks and their hightech pool building system. Good vids but bit hitech for me.

stick to conventional pool construction mate, it's not rocket science. and don't forget i promised to assist you.

Yep, thanks again....
