Flow characteristics
For optimum performance, it is important to
correct the evaporator capacity. In order to
select the correct size of ETS 6 you will need the
following information:
Refrigerant: HCFC / HFC
Evaporator capacity Q
e
in kW or TR
Evaporating temperature t
e
in °C / °F
Condenser temperature t
c
in °C / °F
Subcooling Δt
sub
in K / °F
Example
When selecting the valve it may be necessary to
apply a correction factor to the actual evaporator
capacity. This correction factor is required when
system conditions are different than table
conditions. Selection also depends on having an
acceptable pressure drop across the valve. In the
selection table, the pressure drop in the liquid
line is assumed to be zero. The following example
illustrates correct selection of the valve.
