Hi everybody
I have some questions, I hope to find answers from yor experiences
I am working on R134 chiller with water cooled condenser and flooded evaporator (water in pipes and ref outside), also on other chillers with R22 with air cooled condenser and DX evaporator(ref in pipes and water outside)
I can not determine how much to be the condenser and evaporator approach, what difference between R134 and R22 and how it is relating to the type of evaporator and condenser.
Also how I determine the cond press and temp regarding to atmosphare or water temperature, the same for the evaporator
Discharge temp how relates to condenser temp

please help
