Introducing
GREE is the only HVAC company on the market that has units to deliver direct Solar PV to VRF outdoor units. Τhe solar VRF system is a hybrid solar-electric air conditioner which can work on zero power.
Photovoltaic direct driven, multi-inverter technology.
Zero Electricity Charge.
Zero Waste with power transfer back to the grid.
Neon Energy brings this new technology to the California marketplace. We stock a substantial amount of the GREE VRF line in our warehouse, so we can fulfill orders quite quickly!
” GREE Solar VRF systems produce a 60 – 70%
savings in energy! “
All DC Inverter Technology to Improve Compression Efficiency
All DC inverter compressor and high-performance high pressure chamber are adopted to reduce loss of overheat and improve compression efficiency from direct intake. Compared to lower pressure chambers, the compression efficiency is improved. A high-efficiency Permasyn motor was adopted to provide better performance than traditional DC inverter compressors.
Sensorless DC Inverter Fan Motor
Stepless speed regulation ranges from 5Hz to 44Hz. Compared to traditional inverter motors, the operation is more energy efficient. Sensorless control technology guarantees lower noise, less vibration and steadier operation.
Maximum Torque Control with Minimum Current
It can reduce energy loss caused by device winding which results in higher efficiency.
Low-frequency Torque Control
It can directly control motor torque, through which fan motor can run at a low speed. Users will feel more comfortable while requirements of the system are also met.
180° Sine Wave DC Speed Varying Technology
It can satisfy demands for different temperatures and is able to save a great deal of energy and provide users with utmost comfort at the same time.
High-efficiency Digital PFC Control
High-efficiency PFC control technology is adopted with efficiency improved by about 1% compared to conventional PFC. For units with rated power of 5kW, approximately 50W of electricity can be saved every hour and 1.2kWh of electricity can be saved every day.
Ultra-long Connection Pipe
Under the subcooling control technology gained by adding subcooler, the indoor unit and outdoor unit of the Heat Pump (Mini) can operate reliably with longer connection pipe.
Wide Range of Operating Conditions
The new DC motor allows more accurate high pressure control, which prevents common high pressure control issues during low ambient temperature cooling. The operation range during cooling and heating is wider.
