Hi Everybody.
I wanted to know if it is advisable to spray water directly on the fins of a large V shaped air cooled condenser or shall i use a celdek evaporative pad before the condenser coils and spray water on the celdek pads.
What could be the advantages and disadvantages of using either...
Hi Friends,
I have come accross a few calorimeter test results for condensers and evaporatos, but the readings do not make sense to me, as i am not exactly aware at what points the readings are made.
can you provide me with some details regarding the schematic diagram of a calorimeter test...
dear all,
i have been using and designing the shell & tube heat exchangers using the book of d q kern. process heat transfer
can anyone suggest a book for designing tube & fin type of heat exchangers used in the air conditioning and refrigeration industry.
thanks in advance

Hi all.
I ve been designing some mini air cooled condeners using shaded pole motors.(5W through 16W)The motors are with ball bearing.
But in USA people usually use the unit bearing motors.
What is the differences between these two type of motos.
I would like to buy the unit bearing motors, any...
what are the general procedures for getting a UL listing for condensers and evaporators.
we also wanted to test condensing unit performances using two/three condensers of different make.
Is ther any perticular agency/test lab in india who can do these type of teting.
thanks and appreciate your...
you can use the below formula to calculate acutal sm3/hr (Nm3/hr) from am3/hr
Actual M3/Hr =
(Nm3/Hr x (273 + measured temp. deg. C)) / 273
considering that there is not much pressure difference.
The pressure difference is basiclayy due to the altitude.
Or the standrad formula is...
thanks speco,
i did try to increase the air flow by chenging the motor pulley dia and increaing the fan rpm.
but even with 20% increase in air flow there was hardly any appreciable chenge in the oil outlet temp.
I thing the coil does have turbospirals inserted into the tubes.
Are the heat...
Hi all.
We are using tube and fin type fin fan cooler to cool the lubrication oil of our 10 MW gas turbine.
During high abient temp. the oil temp. rises very high.
Please inform if there are flow retarders or heat transfer promotors available which can be inserted into the tubes, to increase the...
Hi all,
We intend to buy a helium testing machine to test our coils.
can anyone provide with the names of suitable manufactures of these machines.
I understand that there will be escape of helium gas due to the leakages, is it dangerous for the operators

hi !
could you guys help me source connectors / terminal blocks for two core wire 2.5mm2 (10 amps) for single phase motors having two clip type lug connections and from the power source the wire will be having two pin type lug connection.
The connector will be mounted on a sheet metal frame with...
i tried with a vendor with a cnc machine.
but maintaining the dimensions after machining & brazing and very critical & diffficult. Sorry a garage or even a very good mechine shop are not able to do the job.
