When connected to power, the indoor and outdoor units start to work. When working under cooling mode,
the low-temperature and low-pressure refrigerant gas from the heat exchanger of each indoor unit will
collect and be suctioned by compressor, where it will be compressed into high-temperature high-pressure
gas. After that, the gas will enter into the outdoor heat exchanger, where it will exchange heats with the
outdoor air and become refrigerant liquid. Via Y-type Branching pipe or Branching collection pipe, the liquid
will flow into each indoor unit. The liquid will be decreased of the pressure and temperature by throttling
element. After that, the liquid will enter into the indoor heat exchanger, where it will exchange heats with the
air to be regulated in the room and thus become low-temperature low pressure refrigerant gas. The
process is cycled repeatedly to achieve the purpose of cooling.
