2.4 Product Working Principle
2.4.1 Working Principle Introduction
The outdoor unit of GMV6 HR multi VRF unit can be realized by parallel combination of modules,
and the indoor unit can also be composed of multiple units in parallel. The working principle is as
follows: when the indoor unit is running in the cooling mode, the outdoor unit starts the outdoor
module according to the running load demand of the indoor unit. The outdoor heat exchanger is used
as the condenser of the system, and the heat exchangers of indoor units are connected in parallel as
the evaporator of system. It realizes the adjustment of the air temperature and humidity for indoor
space through the return air circulation of the indoor unit; when the indoor unit is in the heating mode,
all the four-way valves of the outdoor unit module are switched to the energizing state, the outdoor
heat exchanger is used as the evaporator of the system and the heat exchanger of indoor unit is used
as the condenser of the system. The air temperature and humidity in the indoor space is realized by
the return air circulation of the indoor unit.
