Hi All, Thanks in advance for any comments.
Ive been having a friendly discussion with a A/C tech who is much my senior regarding a pair of condensors we are replacing on board a large sailing yacht that i work on. The question is regarding the cooling water flow through a water cooled shell and tube condensor, in our case salt water cooled. The condesor is a 2 pass on the water ( throught the tubes) side unit with hot gass entering from the top (through the shell) and cooler liquid out of the bottom. My question is does the water initialy enter at the top to contact the hot gas first or through the bottom to further cool the colder liquid refrigerant in the condensor.
I belive the cold water should flow opisite to the direction of the gas/ liquid ie warm water before it exits contacts hottest gas and coldest water contacts coolest gas.
He has 25 yrs + experience hence the reason im asking you guys and trying not to be a young punk know it all.;)
thanks
