So i was hoping some one of preferably many here will have some input on this as i cant seem to find any good info on it.
Its alot of questions and i can only hope some one are willing to help:)
When it comes to Hydraulics, mechanics, welding and electrics i have no problems but this chiller thing is totally new to me so it will be a learning curve.

I want to build a water chiller to be fitted inside a computer desk. This desk isnt made yet, only drawed up in sketchup. But before building it i want to see what space is needed for this chiller.

There are pre made chillers out there like!
Koolance - https://koolance.com/450W-chiller-subassembly-vlx-450
Aspen Chillers - https://photonicsolutioncenter.com/sites/default/files/LCM-600-1200LowRes.pdf
Hailea Chillers - http://www.hailea.com/e-hailea/product1/HC-500A.htm

I want to build a chiller similar to Koolance/aspen but how big condenser and evaporator can i have to a certain compressor?
When reading Hailea info they say The evaporator is cooled by a Huayi AE1370YZ compressor that's filled with R134a refrigerant. This compressor is rated at 350W, but due to the huge evaporator, the HC-500A itself is rated by Hailea at 790W (enough to cool 1,000 litres of water to 23°C or 500 litres to 18°C).

So in my understanding they have added a bigger evaporator in the system to get better capacity cooling from a smaller compressor?
That must also mean the condenser must be in line with the evaporator then?
How do we see the cooling capacity on the evaporator and condenser in w or BTU/hr?

If we look at the Koolance vlx 450 as a starting point. what is needed to minimum double the effect on that in terms of cooling capacity?
Can we look at 3 examples below!

Aspen 3,8cc Twin series - This allready reach 1200w - 4094Btu/hr cooling capacity but how big are the evaporator and condenser
Danfoss BD50F Compressor - Can we build with this compressor to reach 900w - 3070 Btu/hr or more cooling capacity. If so what sixe of evaporator and condenser is needed
Danfoss BD250GH Compressor - Can we build with this compressor to reach 900w - 3070 Btu/hr or more cooling capacity. If so what sixe of evaporator and condenser is needed

Info on Danfoss - http://files.danfoss.com/TechnicalInfo/Dila/06/bd_compressors_04-2007_pk100c802.pdf

Does any one know where to buy the Aspen 3,8cc cpmpressor?

Well lets start there:)
 
No one in here have any idea?

If any one have some links to similar projects or info i would highly appreciate that to:)
 
Not sure we have many chiller users especially home made chillers. I use water mix from a deep freezer for benching to test before LN2 and there may be a couple with purchased chillers. Afraid it's just not that popular.
Do you have any friends in the HVAC business? They might have better answers.
