Gree Energy Recovery Ventilation Systems

Energy recovery ventilation ERV is a type of ventilation system that can recover the total heat of indoor air to save energy. This system is widely used in residential or commercial building. Filters and heat exchanger can be easily taken out from the access for cleaning.


Internal air filter keeps the fresh air introduced into room pure and dustless. With antibacterial and anti-mildew materials, the heat exchange core guarantees healthy air. The unique by-pass mode can reduce power consumption of fan motor to prolong lifetime of heat exchanger core.

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 with low pressure chamber, the compression efficiency is improved. High-efficient permasyn motor is adopted to provide better performance than traditional DC inverter compressor.

Technology of Maximum Torque Control with Minimum Current

It can reduce energy loss caused by device winding so as to realize higher efficiency.

Wide Range of Condition Range

The unit adopted DC motor with more accurate high-pressure control, which effectively solves the high-pressure control problem in low ambient temperature cooling. So, the operation range in cooling is wider.

Top advanced light and compact size

GMV5 slim adopts small and compact size design. The dimension of the unit is 1430(H)x940(W)x320(D). Compared with the normal product with the same capacity with the same capacity, size and weight are reduced a lot.

Easy installation with lower construction cost

The outdoor unit of GMV5 slim is with small size and light weight. No need fork lifter and crane for movement and installation.

180° Sine Wave DC Speed Varying Technology

It can satisfy various places’ demands for different temperature and is able to save a great deal of electricity and provide users with utmost comfort at the same time.

Sensor less DC Inverter Fan Motor

Step less speed regulation ranges from 5Hz to 44Hz. Compared with traditional inverter motors, the operation is more energy-saving. Sensor less control technology guarantees lower noise, less vibration and steadier operation.
