Great news in Tower Suite this week.
As you know, Evaporative condensers differ from evaporative coolers because while in the former we have a refrigerant condensing inside the tubes, in the latter we have a mono-phase fluid (which can be a pure liquid or a liquid mixture) cooling down as it flows through the tubes.
We have introduced two interesting innovations in each of the two modules, Evaporative Condenser and Evaporative Cooling, available separately, which constitute our TOWER SUITE! Let’s see them together in this brief update. We would also like to remind you that Unilab will be exhibiting at CHILLVENTA 2018, pavilion 7, stand 121! In Nuremberg, 16-18 October 2018!
EVAPORATIVE CONDENSER: WE INTRODUCED THE SPLIT SECTION!
The air coming out of the evaporative condenser might be very hot but is also very humid. Being very humid, the air coming out creates white plumes of water vapor (fog) that falls onto the ground, freezes & get very slippery, with the risk of people falling and getting injured. How to solve this? A finned pack heat exchanger, put over the spray systems: in Italy we use to call it “anti-plume”. This is most widely known as SPLIT SECTION. The hot refrigerant flows into this coil h.e. and gets cooled down, then enters the condensing coil and condenses. This prevents the creation of plumes & the risk of freezing. We are proud to announce Unilab introduced on its innovative EVAPORATIVE CONDENSER software the calculation of the SPLIT SECTION!
A change in this case aimed at making the program user-friendly; We introduced a graphic where In the x-axis there is the water flow, in the y-axis there is the power. There are 2 curves, one is given by the first principle of thermodynamics, i.e. the power is equal to the flow rate for the specific heat for the thermal difference, the other instead represents the capacity of the exchanger; they cross at one point. This helps the user understand precisely if the calculation made converges and where it balances! In case the calculation does not balance, the two curves will be shown as non-converging, thus helping the user in the calculation. Here a screenshot:
