The outdoor unit is regulated using dual electronic expansion valves within the regulation range of 960
stages to accurately realize the flow control between the indoor unit module and outdoor unit module, so
the system operates more stably.
Heating can start quickly.
1.4 Humanized engineering operation
The unit is characterized by automatic address allocation and non-polarity communication.
The unit can perform automatic debugging and fault detection.
GMV5 HR has five automatic debugging functions.
Automatically allocating indoor and outdoor unit addresses
Automatically checking the quantities of indoor and outdoor units
Automatically detecting internal faults of units
Automatically starting debugging
Judging pipeline exceptions in real time
The units provide three emergency functions: module, compressor and fan.
The units can recover refrigerants in two modes.
1.5 Intelligent management
The units are designed in the dual-energy saving operation modes.
Along with penetration of energy conservation and emission reduction and increasingly strict
requirements for power utilization in cities raised by the state, a lot of cities will issue corresponding
power rationing measures in the peak of power consumption, especially in summer. Gree GMV5 HR
conditioning units unit provides two energy saving modes for users to select as needed and meets the
requirements for off-peak power consumption and power brownout in cities.
Energy saving mode 1: When the unit is set to the automatic energy saving mode during operation,
the system automatically adjusts and controls the target parameter according to the operating status,
and greatly reduces power consumption of the whole system
.
Energy saving mode 2: When the unit is set to the forced energy saving mode during operation, the
system forcedly limits power output of the system.
The unit is provided with the energy consumption analysis function and corresponding solution.
The unit supports the emergency shutdown function.
Without remote monitoring, the outdoor unit can directly intervene in the fire alarm linkage signal, and
the whole system can stop immediately in case of an emergency to avoid more risk losses.
The unit has the management function by area.
1.6 Ultra-long piping distance design, with the maximum piping length of 1000m(3280-
3/4)
In comparison to the traditional water chilling unit, the VRF unit shows the strength of simple and
convenient engineering piping. Gree GMV5 HR inverter VRF unit more significantly displays the strength
of actual engineering piping, and the air conditioning system can be flexibly applied to various buildings
more simply and freely, reducing the engineering installation cost for users.
1.7 A single refrigerating system, able to connect to a maximum of 61 indoor units
Gree GMV5 HR can implement combination of module units and connect to a maximum of 61
indoor units (the quantity of connected units ranks first in the field). It is more applicable to large-sized
commercial office buildings or aparthotels.
1.8 Wide operation range
Operating temperature range: -5°C to 52°C(23~125.6
℉
) for cooling; -20°C to 24°C (-4~75.2
℉
