R134a / Water Heat Exchanger Sizing
Hello everybody
This is my first post at these forums and I hope all goes well.
I'm in the design phase of a water chiller for my PC watercooling loop, which cools the CPU and chipset of my DFI motherboard, as well as the GPU's TEC waterblock (Swiftech MCW60-T).
I already have a condensing unit by danfoss (114G1705) with a TL3GXT2 compressor. The refrigerant is R134a. I have the PDF for this unit but I cannot upload it since it's 1.24Mb. I can PM it to anyone willing to help... I also have photos of the condensing unit if needed.
I need to design and manufacture a shell and tube HE to cool down the watercooling fluid (water) to 20° C. The pipes carrying the R134a will be copper and the shell of the HE will be stainless stell insulated with 13mm Armaflex. I estimate the total heat load from the various PC components to be around 500 Watts and the total volume of water to be 2 lt.
Any help will be mostly appreciated and thanks for your time.
