    High hydraulic separator inlet velocities

    I am calling it a buffer tank because it is a volumizer in the system. Based on the inlet/outlet locations (one across each other), there will be a certain level of stratification in the system. Why would you have diagonally located inlet/outlet? https://www.fiorini-industries.com/en/vkd/...

    High hydraulic separator inlet velocities

    It does not have a plate. It has perforated pipes on top and bottom. Snip attached. As you mentioned, this buffer would behave as a big pipe.https://files.engineering.com/getfile.aspx?folder=65a88190-68d2-466c-b4a1-07c9bba1ebc7&file=Buffer.png

    High hydraulic separator inlet velocities

    Hi, I agree on product data. I am sure this is not a separator as it is, but my idea is to use it as one. I believe the manufacturer didn't state in its product data such an application. However, dont see a reason why 4 pipe buffer tank needs baffles, maybe if it has 2 connections then it would...

    High hydraulic separator inlet velocities

    Dont have a design manual but will try to get it. The manufacturer of the equipment is not listed. The thing is...this is not a typical design situation...we are installing this chilled water ramp only for a 3-day test and then we disassemble it...so we must work with rental equipment only...

    High hydraulic separator inlet velocities

    Hi all, would need some advice on the low-loss header application. Currently, I am designing a chilled water test ramp with rented equipment. The chilled water system will be with the primary-secondary pumping arrangement. When the load comes online, I have sufficient liters of water as per the...

    Rate of absolute humidity increase in space

    Yes, there is ventilation provided which is planned to supply fresh unconditioned air from the outside, which the units should dehumidify, but, with it on, humidity increases even faster. The exhaust from the server room would transfer to another one, however, with the fan on, there is...

    Rate of absolute humidity increase in space

    Hi all, I could use some advice regarding the issue of increased humidity in the building. I am currently on a project that is being built with a dew point of the outside air of 23.2°C (x=18g/kg). The space is cooled by the perimeter CRAC units which also have to cool and dehumidify outside air...

    Draining of heat exhanger

    I can totally agree with this one, however, such decisions are outside of my reach as my job is only to integrate this unit into the system. I see your intention here, will check out this possibility. Would the even better option be to have some sort of preheater on the exit of the bottle, and...

    Draining of heat exhanger

    The current orientation is right, since the HE is an integral part of the cooling unit, and the unit is basically a cabinet, there is no possibility of the wrong installation, it is just how it is. There is no piping on the other side, and there is no drain for sure...also the lower part of the...

    Draining of heat exhanger

    What vacuum technology/pump could be the best fit for such an operation? Should I be worried about freezing of water inside since it looses energy(temperature is going down)? There is no possibility to heat HE, maybe just have some hot air blower around and have temperature around HE at...

    Draining of heat exhanger

    Could you point out what kind of technology I would look for? Compressed hot dry air? High-temperature nitrogen purge? Is it possible to remove such quantities of water by vacuum? I believe oil sealed vacuum pump wouldn't be any good since the oil would mix with water, and frequent changes of...

    Draining of heat exhanger

    The unit is rated for 16 bar (tested with water). Unfortunately, I am not aware of the air pressure in the factory...I think compressed air is available, but not sure if could be used as such since the distances for compression stationary lines are far away from the assembly grounds. Could a...

    Draining of heat exhanger

    Unfortunately no, the unit is fastened to subtrack or floor, and it is usually packed between the other equipment(standing cabinets)

    Draining of heat exhanger

    Here is the real illustration Unfortunately, I don't have the schematic for flow path inside heat exchanger, just for connection points. We are hydro testing the unit, and after that, it is shipped to the site, however, during transport and storage the remaining water could be frozen (we...

    Draining of heat exhanger

    Is there a way to know how much static pressure would I require in order to push the air through the water? Do you usually heat up nitrogen before being introduced into the system? Another idea would be to vacuum and boil out the remaining water, however, I am not sure what kind of vacuum pump...

    Draining of heat exhanger

    In one of the CHW projects, I had to deal with a cooling unit heat exchanger whose IN/OUT connections were located in the middle of its overall height. After the hydro test, the heat exchanger could not be drained properly, as shown in the picture, as the lower part of it would be flooded since...

    Galvanizing piping after welding

    Hi all, firstly thanks for all comments and opinions. Some of you have proposed other solutions, which if you ask me, are valid and could be used to install chilled water piping. However, we are designing the additional capacity for the already built plant based on the already agreed on...

    Galvanizing piping after welding

    We have a requirement from the customer to install a chilled water system with galvanized steel, and such that we first have to weld and connect steel piping and after the hot works have been done, dismantle the piping and take it for galvanization, after which the installation should be...

    Lithium Ion Batteries Exhaust Ventilation

    Yes, but before burning and exploding, the batteries go to thermal runaway and produce explosive gasses (hydrogen, carbon monoxide, etc.) which could be vented to ensure the LFL is below so there is no explosion. I have read that during thermally runaway both hydrogen (LFL 4%) and carbon...
