    Dust collector to filter Outside Air

    Hi! To Quark: Can you be more specific? Let us know some description of what you mean? Some sites, some material, some data related? Is that possible? I'm in a middle of a similar problem, which I will share with the Forum. zzzo

    Sequencing VSD and constant speed chillers

    Hi IMOK2 ! I tried to acess to the site http://www.automatedbuildings.com/, and I was no able to reach it. Can you confirm that reference you gave? Thank you! zzzo

    Pressurisation of Corridor in Pharma Plant

    As an additional: Arquitechure can solve the problem, once for all: - two doors, - a space in between, to enter into a production space, from the corridor, - you open the first door, - you close it afterwards, - then you open the second, you are in and clean! - Now, a small "secret", you...

    Pressurisation of Corridor in Pharma Plant

    - First, I don't think corridor associated with any dirty functions at all! - 2nd, the corridor is communication/circulation space to others production spaces, so it must be the cleanest space in the facility! - Third, the architecture of the building must consider all those implications and...

    Fouling Factors - Effect of Regular Cleaning

    Hi Fellows! I'm sorry, if I could suggest to skip to main initial question, nevertheless, these matters are correlated, so we can discuss them transverse way, may I say. Speco: Once more, thank you for your great feedback and your will to help, as well. I will prepare next week some updated...

    Pressurisation of Corridor in Pharma Plant

    Hi! Consider some additional points: -Following the last Quark's post, you can get almost standard solutions to face the door openings problem. - When there is any static pressure change, that is recognized by a (or several, in this case it is used the mean driven value) pressure...

    Basic Thermal Analysis References

    Hi! I whould suggest a strong coffee instead to insist on beer... But, I understand, I still remember those good all days (& nigths!!!) along the time university... By the way, Themaniac which is the overall heat-transfer, when a guy is plenty of beer ?? Is he be able to think, to realise...

    Sequencing VSD and constant speed chillers

    Hi! A few comments: -Those kind of chillers, certainly have several thermodynamic groups working sequentially along the 1º('s?) circuit(s) temperature range. -If we define/combine all the chillers we can put them to work sequentially to respond to all possible simultaneous demands. We have to...

    Fouling Factors - Effect of Regular Cleaning

    Hi Speco! Thank you for you reply! You mean that the surface ratio you refer, can accept "grosso modo", some quantity of dust. As a matter of fact, we have a lots of thin and very dry dust. What you say, suggests me to go deeper and take a look about the parcial internal and external heat...

    Fouling Factors - Effect of Regular Cleaning

    Hi Fellows! And how about fouling resistance on the air-side of a condenser gas coil working in industrial environments with a losts of dust and high temperatures? Has anyboby have some studies about the cleaning processes and frequencies? How much dust do I permit versus minus some...

    Funneling wind

    Hi, Xerxy! What you said makes sense! The windfunnel technology needs flows with significant momentum in order to get good relation between flow momentum and the losses inside of the funnel. Besides that, you should to choose the rigth location and orientation for such ugly funnel...in some...

    Funneling wind

    Hi ACADIEN Please keep on being "crazy", but always doing something you believe on, even in the end, you just goy one more try,... until you get some solution. That´s for that we live in this planet, to do things for fun, as well. Cheers! zzzo

    Compressor chillers or Absorption chillers

    Hi! To Davefitz: From your knowledge/experience what you have to say about absorption chillers, in particular those lithium bromide requiring hot water at lower temperatures at the level of the generator(of course you have to consider a bigger one, as well the absorsor!) around 70~75 ºC (or...

    GEOTHERMAL HEATING

    Hi WILG I'm working with a program, "TESTPoint", suitable as an interface for Data Acquisition & Processing Systems, and facing some problems, because this prog do not accept in an easy way figures or the "grafhical thing" you presented here. Can you provide us some...

    Why do balloons hit a wall of air?

    Hi WILG! I will, in this coming week-end to go deeper on the subject. In meantime, I'm in the middle of much work. Sunny but rather cold, 2 - 3 ºC (or 35 to 39 ºF) during the day. Take care. Cheers. zzzo
