#LASERDRW 3 TUTORIAL CUT IN TWO PASS PLUS#

… Maybe try again this weekend ( supposed to be 107 degreees plus outside woo hoo) Since I still am using the laserdrw software, not very friendly. Still not comfortable “wasting” acrylic yet. Tried cutting foam (had nice fire), paper, leather and wood. I expect that an air conditioner pointed toward the laser air intake would increase the duty cycle for those in hot climates.įinally got braver over the holiday weekend. That air conditioner was working alright, it was doing it’s best to cool the engine bay. A simple length of tubing that halfway across became a freezer element. I saw heavy frost on the line, right in the middle of a 2 foot span… there was a dent in the line that reduced the capacity by about half - That dent became the expansion valve!

Everything was as it should be, so I’m leaning on the grill scratching my head when I notice a small 1/8' tubing line that ran along the engine bay. To give an idea of how simple the system is, I once had an auto air conditioner that wouldn’t blow cool air, and couldn’t figure it out.

Then the fluid returns to the compressor. The coils have a fan blowing across them to cool the air in your fridge or air conditioner, and the fluid condenses (in that little extra radiator you might have seen on your car). The compressor pressurizes the fluid that has to pass trough an expansion valve, which is just a restriction that has the effect of causing evaporation immediately down stream of it (low pressure side). There is a high pressure side and a low pressure side. Refrigerant has a very low boiling point for efficiency. A fluid absorbs heat as it evaporates, and releases it as it condenses.

Remember the old trick of licking your finger and holding it up to detect which way the breeze is blowing? Basic principal of refrigeration.
