    Sir we always use danfoss Expansion Valve but at some place we want to reduce the cost of the machinery so we want to use capillary tube but there was a big problem arises we don't know what is the formula to calculate the size of capillary tube according to the temperature that we want ? Please sir make a video on this.

    I design a system with MTZ-40 compressor, using thermo expansion valve R404a -40 / 10. The ice would cover all the compressor after a few minutes running. What could I do abount that?
