2 BASIC OPERATING PRINCIPLE
Outdoor units of Photovoltaic Direct-driven Inverter Multi 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.
