Combined with the previous optimal control analysis of
the injection pressure, it can be concluded: there will be an
optimal injection pressure for the maximizing cooling
capacity of the injected system with a fixed injection port
location; there will be an optimal injection port location for
the maximizing cooling capacity of the injected system with
a fixed injection pressure; the optimal injection pressure/
injection port location for maximizing COP is either the same
as the optimal injection pressure/injection port location for
maximum cooling capacity or is varied in the direction that
decreases the difference between injection pressure and the
pocket pressure at the start of injection.
