hi all is any one knows a site to get hourly record weather data i mean DB, WB , RH temp. i really need it

hi every one well i have a project contains 3- water cooled chiller and 3-cooling towers at and i ve been asked to make a schematic dwg for these equipments ,to control the cooling water flow rate i will use three way valve my question is where is the best location to put is it before the...

gpm for the condenser u means evaporation load x 1.17 = condenser load say cooling load =600 TR then the condenser load = 702 TR then the cooling tower flow rate = 2106 gpm right? but if i had a chiller the water temprature difference = 16F then the how much the condenser cooling water...

the cooling water thermodynamic analysis used for cooling water chillers is 1TR=3.5KW= m CPw (twi-two) m= 3.5 /(4.18 x (32-37)) = 0.167 kg/s volume flow rate = 2.65 gpm is that right? cause i know that as a rule of thumb that 1 TR needs 3 gpm cooling water

THANKS ALOT ZESTI :)

dear all in an industrial project the chilled water pump is described as 15mAq as head by the designer i cannt figure out what is that unit mAq .i need help

HI i am using a 100% FA A.H.U. with a cap. of 2000 L/S with heat recovery this AHU IS DX PACKAGE UNIT HAP output data was that the total coil load = the sensible load and it cannot be right ! there is for sure a latent load cause when i changed the type of the AHU to tempering it calculates...

why is the outdoor cooling only type is limited capacity comparing to heat pump? the project is at tropical climate i dont need heating applications

dear marcoh R.H. couldnt be controlled at fan coil unit as it doesnt contain demumdifier or reheater so i ve reached that any place needs a certain R.H. i must use a n A.H.U. even if the capacity is small because i ve tried to increase the by pass factor to manipulate r.h i even tried to...

hi,, i am using daikin vrv software to design a redential system but i cannt determine what is the difference between cooling only system and heat pum??

yes about carrier software hap-4.3

the hospital areas needs to be served by define air circumistances (r.h.%, temp.,ach...etc) how can i make control R.H. value or make it as an input data at hourly analysis prgramme?

HOURLY ANALYSIS PROGRAMME HAP

hi guys,, the designing of specified areas at hospitals needs a define value of R.H. like 70% the hap define the resultant r.h. on waht bases and if i want to change the relative hunmidity what shall i do? thanks in advance

thanks HevïGuy but it doesnt include the valuse of steam flow rate for the equipments iam trying to find refrence for steam applications at laundaries hospitals ect... any help?
