    internal temperature conditions

    hi everyone, just to let everyone know who commented on this forum that we have won the case, the approach we took was to highlight the fact that the developer did not comply with the specification and therefore not fulfilling their contract. the court agreed with this and now is required to...

    internal temperature conditions

    thank you everyone for the comments but i think this is getting a little side tracked. i am a very experienced designer and have many years experience in the application of a/c systems to various building types. the building in question is an apartment building and the client in question owns...

    internal temperature conditions

    If an air conditioning design brief nominates the design internal temperature as 24 deg.C DB +/- 2 deg.C, what is the internal temperature used for the cooling load calc. 24 deg.C ?? 26 deg.C ??? Are there any ASHRAE, CIBSE guides that reference the above.

    internal temperature conditions

    the wording of the spec is 24degC +-2degC, and as IRstuf says this could also be 26 +0-4, the external design condition is 35degC, the problems are that we are getting an internal condition above the design condition on days that are under 35degC, this is mainly due to direct solar gain as on...

    internal temperature conditions

    the situation is that the developer claims the design temp of 24+-2 means the a/c is sized to 26degC, we say this is incorect and that it should be designed to meet 24degC with a 2 degC control band width.

    internal temperature conditions

    what i am after exactly is a document from ashrae, cibse etc that states that if my design control temperature is 24+-2degC the load calculation is based on 24 and the thermostatic control is +-2, i am in a legal situation where a client is suing a developer because the a/c is unable to maintain...

    internal temperature conditions

    we all know what internal temperature control conditions are, i.e 24degC +-2 etc, but where is it stated that 24 deg.C is the design temperature and that +-2 deg.C is the control range.

    Turbocor Compressors in Operation

    hello there, i take it from you message you left on my thread that you are from melbourne as well, funny enough i am currently doing a project where the client has requested these chillers. we are installing 1 220kW and 2 350kW machines, i am a bit sceptical about how good this really is but...

    turbocor compressors

    cheers absrbrtek, i'm after some comments from people who have installed them, i'm in melbourne (Aust), there have been a few installed here but the owners are saying little. i've worked out a payback of about 6 years against a York so in concept they are great but i think they aren't telling us...

    turbocor compressors

    does anyone have experience with the turbocor compressors? i'm currently looking for a project to use them but am a little cautious about useing it as it is a new product without a proven track record. any comments please.

    convert imperial formula to SI

    yeah, that is great, thankyou very much.

    convert imperial formula to SI

    i need some help on understanding a formaula i found in the ASHRAE book, Ground Source Heat Pumps. it relates to the cooling capacity of a ground water system. it is, gpm = ((qc x 12000)/(500 x (t_gwo-t_gwi))x((EER+3.41)/EER). the first part of this formula is obviously; m=q/(Cp(t2-t1). and...

    ground water heat pump

    can anyone help me with the approx cost of a ground water heat pump system? i am doing a payback analysis for a system to be installed in a typical office. ignoring the building side of the system, what would be the cost of a system capable of say 200kW. this would include the borehole, pumping...
