TEV Pressure Difference
Hi guys, let me start by wishing everyone a happy new year! (better late than never )
I was thinking about a system which was over condensing, causing minimal temp lift and what effects it has on the system, I was wondering at what pressure difference over a TEV would refrigerant stop flowing?
also, if this where to happen how would the system behave? would it trip on LP as refrigerant gets pumped into the high side? (suppose it probably depends on system size) or would the high side raise in pressure and then refrigerant would flow over TEV for a short while then keep repeating this over and over with little refrigeration effect?
also what pressure difference over other types of expansion device, capillary and EEV mainly before refrigerant will stop flowing?
thanks for any help in advanced! love the learning
