Rated capacity and Ordering
1
) Rated capacities are based on
Condensing temperature t
c
= 32°C
Liquid temperature t
l
= 28°C
Evaporating temperature t
e
= 5°C
To obtain an expansion valve that will function correctly under
dierent load conditions it is necessary to consider the following
points when the valve has to be dimensioned:
These points must be dealt with in the following sequence:
1) Evaporator capacity
2) Pressure drop across the valve
3) Correction for subcooling
4) Correction for evaporating temperature
5) Determination of valve size
6) Correctly dimensioned liquid line
