    • LOW INDOOR AIR FLOW = Low superheat & suction pressure. Low to normal head pressure. High indoor TD. High to normal subcooling. Not much effect on current draw.
    • MILD LOW OUTDOOR AIR FLOW = Low superheat & subcooling. High suction

  2. Refrigerant will NOT get you high, it will KILL you!

    Why are people huffing refrigerant? I am a refrigeration technician who works around refrigerants and I have found myself in situations were I have been exposed to higher than recommended limits. I can tell you that the feeling you experience is nothing like the high you get from marijuana. I am seriously concerned for my health at these times! The refrigerants are colourless with a faint sweet odour. Overexposure leads to dizziness and loss of concentration because the vapour displaces
  3. Heat reclaim condenser

    Dear Colleagues,

    I've "designed" something and it looks like Idea in heat reclaim/heat pump solution.
    Here is my diagram.
    The reason is to use water condenser simulteneously with air condenser. Water condenser has liquid volume capacity so there is no receiver. If there is need to recover condensing capacity water enters water cond. and refrigerant starts to condense. % of water condensing could be any.
    I doubt if hot gas could heat up liquid refrigerant ...
