    Industrial Ventilation Rates

    Whar Trashcanman declares sounds logical: - the rate he refers, means 10 to 12 times the volume of related space. Or, the air is replaced every 5 to 6 minutes.

    Industrial Ventilation Rates

    What i mean, unless we dealing with a very contaminated environment, the necessary and higher ventilations rates are usully obtained based on the criterious concerning internal heat sources. Welch

    Industrial Ventilation Rates

    Pumhouse means as well internal heat sources. This can be related with with your question and to impose some ventilation rate, as well !? welch

    STEEL INDUSTRY

    To MintJulep! Q1: All the time. That's an industry 24/24h with some breaks (during electricity high rates periods). To the rest of all other questions: That's a process requirement: I have to cool the steel bilets down to 500 ºC at a certain rate in order the material of those bars (steel)...

    And what shall I do with the hudge quantities of those grown tomatos? Another Pamplona scenery and invite a lots of tourists?.... Can you imagine how much heat is radiating (surface temperature at 900 ºC (1652 ºF) from a 16 yards bilets cooling table, file simutaneous lanes: 16 x 30 x 5 kW =...

    A Heat Pump a good choice?

    To Gunnar Englund: I wonder how the (COP) SEER varies all along the year and all along the day tipically? When you state: "We had less than half the total cost with the heat pumps". That could be understood as a figure of SEER bigger than 2. Is it?. If you payed 4000 USD for your heat pumps...

    A Heat Pump a good choice?

    Hi Gunnar Englund! Can you show us, how do you arrive at a "pay-back time is less than a year". Specifically, how is the SEER profile all the year-around ? welch

    A Heat Pump a good choice?

    If I'allowed, just let me add a few more points for discussion: 1.So I ask to the Forum about the so-called solar heat-pumps I mean those which has the condensing module in form of black metalic surfaces in the role of solar pannels. My main doubts is that this device is trying to pretend to be...

    VENTILATION SYSTEMS IN PHARMACY INDUSTRY

    Hi, Fellows! Drazen, I must say that you got your shoes on the real world. That's right, it's a small company. The approach has to be carefully balanced for a system, which has to fulfill the Interior Air Quality IAQ requirements in the first project phase and leave the conditions, ex.: for...

    VENTILATION SYSTEMS IN PHARMACY INDUSTRY

    Again to DRAZEN Suppose you do nothing in this case, or just the minimal. They will blame you as well. The question is to get here a balanced solution, consider the normative requirements. The 2nd aspect is to consider the design process in two phases, related to the outside QA, (that implies...

    VENTILATION SYSTEMS IN PHARMACY INDUSTRY

    Hi DRAZEN! You just pointed out the main aspect,i have to deal with. I must say that I got already some data you mentioned (in written), an I have to consider those, as enough inputs like the chemo drug list, the layout, to do my study. The task now, is to get some "grey rooms", I mean to...
