    Dear Zafar bhai,
    I am a novice, not a technical person.
    I am from the garment industry.
    It's a labour intensive industry.
    Factories may be located in coastal region like Bangladesh, Sri Lanka, Chennai, Mumbai, Kenya.
    High humidity and high temperature are a big problem.
    Also need frequent air change to reduce carbon dioxide.
    The industry cannot afford air conditioning.
    We just need to reduce temperature by say 5 degrees and also reduce humidity.
    The industry needs cost effective solution.
    Pushing "dry" air and pulling out stale air, can create a current, which will make the atmosphere within the factory bearable and pleasant for workers.
    Factories are large - about 100,000 sq ft and height of about 7 mtrs to 12 mtrs.
    Would love to hear from you - a solution that you can offer.
    Piyush Vyas

    I think you should mention the curve line is the dew point. In case the ADP does not reach the curve, there would be no dehumidification and only cooling of air.

    since the specific enthalpy units is in (KJ/kg dry air) should we convert massflowrate to volumetric flowrate first and then divide by specific volume at entrance conditions? after which multiple to delta enthalpy to cancel out the units?

    • @AlecVista
      @AlecVista 4 ปีที่แล้ว

      converting mass flowrate to volumetric flowrate using the ideal gas equation assuming initial conditions are ideal

    Sir I want to ask you two questions. Kindly reply me. Thanks...
    1. What about humidification and cooling at same time if we consider Relative humidity 100% for inlet and outlet cases for suppose???
    2. How to plot that in psychrometric chart??

    hello sir, very nicely explained. I have few queries pls do clarify if you can.
    Does this dehumidification go exclusively with cooling?
    for example, I want to remove only the amount of moisture (humidity ratio or absolute humidity) without reducing the temperature of air and water vapour mixture? can it be possible?
    I want to reduce relative humidity while dehumidifying? will it be possible?
