3.19.1 Operating logic

This option allows the unit to have two functions:
a) Cooling mode: inject liquid into the suction line to reduce the temperature of the compressor
exhaust gas.
b) Heating mode: it pushes most refrigerant from the condenser and the liquid receiver to the
evaporator. This establishes a higher pressure and temperature during heating mode, increasing
performance and efficiency.
