What is the difference between Droplet Separator and Drum in TESPY ? I am modelling a Heatpump cycle where the refrigerant is exapnded and then flash tank separates into saturated liquid and saturated vapour. The saturated vapour gets injected into the second stage of compressor and the saturated liquid proceeds to the next expansion valve and then evaporator. I am not sure which component can be useful for my flash tank is it Droplet Separator or Drum ? If any one has any advice/comments that would be helpful for me. |

Hi @ronitd07, the drum has two inlets and two outlets. The first outlet is saturated liquid, the second one saturated vapor. This is the same as the in the droplet separator. What is different is, that the drum recirculates with another heat exchanger so there is a net energy input. The first inlet is supposed to be connected to an economizer, the second inlet to an evaporator, which is connected to the saturated liquid outlet of the drum. In your case, I would connect the refrigerant to the valve for expansion and then attach the droplet seperator. Best |
