1.11 4-way Valve Control
Purpose The purpose of the 4-way valve control is to control how the superheated refrigerant passes through
the 4-way valve. The 4-way valve control carries out the changeover switching of the 4-way valve. This
changeover switching is only carried out during operation, because a certain pressure difference is
required to move the internal cylinder.
