new 12000btu 3.2 kw chiller unit as a school project

hey folks im new here so hello

on this project im going to make this as a serius thing not like all the other fails ive done in the past. so i aquierd a r410a aircon that i will rebuild to a powerfull chiller yes yes i know about the high discharge pressures of r 410a an so on but i like tat its so effective of its task so thats why i went wit r410a this time also that its kinda cheap here in norway so heres som pics of the aircon itself also here a littlie clip of it running es love clips http://www.youtube.com/watch?v=qHpVXycFm-s

this unit is REALLY expensive like 1100 dollars new its crazy but i got this almost unused for 70 bucks . so now i just need a vacum pump and gauge set for the recovery and modding of everything i also need a txv and a plate hx im gonna order that soon :shrug: the txv is a Danfoss tuae expansion valve with a 03 orfice rated for 2.9 kw and i have not yet desided on what hx to get :up: but heres some more pics of stuff i use and parts for the system

well heres the recovery compressor its :banana::banana::banana::banana:ING huge copeland dwm 2 cylinder simihermetic compressor ]

and the recovery tank wich i made today from an old reciver i had

and the filterdrier, sightglass, contoller for the temps, some relays and compressor cooling fans




and i dont have dry nitrogen but i have a dry argon co2 mix here so that wil be my shield gas and purge gas


so thats all for today thanks for watcing this and remember this is a little project for me i dont do this for a living im only 16 so i do this for fun xD

ok progress sofar ive recoverd the rifigirant r410 a to a reciver and that is in my frezzer wich holds -48 C its REALLLY COLD almost like a cryostatic frezzer but it sits there happily at 1.5 bar witch is much less than what i thougt but when i turn the tank i can hear the liqid in there but ive found a cabinet to put this in and so here are some more pictures

NEW TOYS







heres my work space its bigger but went out of battery



i also got a 19mm shet of armaflex for insulaition of the heat exchanger its really expensive


and the box ill have everything in perfect fit




and heres the 1.5hp compressor




this is all for now and thanks for waching

high pressure swich its a bit too expensive for my liking as im almost getting bankrup by all of this but if i can find a cheap used or unused one HELLYEA ill use it but i only have stuff thats rated for 28 bar and stuff and the liqidline recidver is under planning its gonna be made out of some +30mm copper pipe with ends but the problem is getting a mall lenght og that tubing size i can only get it in 5 meter bundles grrrrrr but ill keep looking. but ill try to find a solinoyd that works i can sweep down to my local hvac place and ask if they have any used ones i can have and fush it with alcahol or r11
i want to go for a 50 plate cus its sooo cheap but im worried that that will become a ******* huge oiltrap and kill the comp and this is going to be for multi use also for lazers and triac cooling and much more but i anm really worried that the heat exchanger will become a oiltrap or else everything is going as far as planned also an aditional question is how high shold the pressure cutout be
