I have a few questions regarding heat exchanger design ? ? ? In a hurry? In a hurry?

1. Is an evaporative condenser something that functions both as an evaporator and a condenser? For evaporators with a heat transfer capacity of 2,700KW to 1200KW, is it better to use a dry-type evaporator or a full-liquid-type evaporator? 3. When the refrigerant water medium in the evaporator is a calcium chloride solution, can TP2 heat exchange tubes be used, with a carbon steel shell? Thank you so much for your answer, god! Thank you! Urgent!
I ask the experts to answer, thank you! !
I’m not very familiar with tube-type systems; I know a bit about plate-type systems. When analyzing plate-type systems, first, it’s used for a specific purpose – it can’t serve two functions at the same time. Of course, there are differences among the patterns on the plates. Second, I don’t understand what’s meant by a dry type system; I only know that a full-liquid system can improve heat exchange efficiency. Third, for calcium chloride, 316L steel seems to be sufficient, but when it comes to calcium, scale formation needs to be taken into consideration. Please forgive any mistakes I may have; I hope experts can give me some guidance

Is NB/T 47012 applicable to pressure vessels for refrigeration equipment? ?
