2 BASIC OPERATING PRINCIPLE
Outdoor units of GMV5 VRF air conditioner can be implemented by combining multiple modules in
parallel. Similarly, indoor units (IDUs) consist of multiple units connecting in parallel. The operating
principle is as follows: When an IDU is operating in cooling mode, the outdoor unit (ODU) can
correspondingly enable the outdoor module based on the operating load requirement of the IDU. The
outdoor heat exchanger serves as a system condenser, and the heat exchangers of cooling IDUs are
connected in parallel to serve as a system evaporator. The circulation of air supply and air return of the
IDU is performed to adjust the indoor temperature and humidity. When an IDU is operating in heating
mode, all four-way valves in the ODU module are switched into energized status. The outdoor heat
exchange serves as the system evaporator, and the heat exchanger of the IDU serves as the system
condenser. The circulation of air supply and air return of the IDU is performed to adjust the indoor
temperature and humidity.
