Well most of the parts are here, but I'm waiting for a few fittings. Turns out
the most difficult part of this system is sizing the freon lines. I'm trying to
keep it all hose for ease of installation. It gets pretty complicated when you're
dealing with a low volume compressor with a high volume evaporator. The
tube sizes are critical since there all these factors that need to balance out,
like head pressures, low side pressures, superheat, orifice sizes, expansion
valves, gas velocity, compressor cooling and lubrication, etc.
Needless to say, I'm learning more about thermal dynamics, and gas law than I really
want to know at the moment. Once I get some new fittings of the proper size,
and then fabricate some special fittings, I will be ready to charge up the
system and start playing with R-134 volume and pressures. It will probably take
several experiments with different expansion valves and high and low side
tubing size changes before I have it all balanced right, but I hope to be generating
cold air this weekend or early next week at the latest.
Will keep everyone posted.
