can someone tell me where i can find information of exactly what is inside and split a/c unit (mainly the outdoor unit) in terms of refrigeration components; pipes, valves etc. (not really electrical components).

im particularly interested in daikin. do they have a technical website or something?

thanks,

paul :)

COMPRESSOR
CONDENSER
EXPANSION DEVICE
ACCUMULATOR (possibly)
ELECTRONIC CONTROL BOARD


All A/C condensing units contain these components, Heat pumps Also have a reversing valve, :)

hi paul,

it would also cotain, leaves from the closest tree, dead lizards, pieces of stikcs that kids push into the fan. :D

the expention device - cap tube will be betwen the bottom of the condenser and the liquid line valve.

cap tube used to be in the indoor unit but it makes high noise when when the refrigerant starts flowing or when there is refrigarnt shortage.

from that reason, it was moved into the outdoor unit.

Try this link - it's to a page on the Spaceair members site and it shows the technical liturature (sp?) for a Skyair system. If you scroll down you will find the schematic for the outdoor unit. Hope the link works as I'm a member but I can't give out my password - if I did I'd have to SHOOT you (as Chemi say's) :D http://www.spaceair.co.uk/cgi-bin/pages/skyair/RYP/RYP-L-B%20121%20tech.pdf

Be patient it takes a while to load and is in pdf format

10 out of ten boys - it is a distributor. :p

Paul - this is the small device on the end of the liquid line where it splits in to many small pipes to distribute the refrigerant equally into the evaporator. Give me the model number of the split and I'll see if I can post a link for you.

Fire Sprinkler mounted upside down?
Distributor? Only one injection soldered of the distributor?
Rest is open? Wouldn't the gas not blow out the others?
:p :D

symbol for venturi, indicates a multifed coil is used.

Hi Frank,

on the outdoor unit it says its a Daikin RXD71JVEA

remember I live in australia so i dont know if that means different model numbers,

if you could direct me th where i could get a piping diagram; that would be great

:-)
