Gree Heat recovery ventilation systems

Gree heat recovery ventilation systems recover latent and sensible heat simultaneously thus effecting temperature and humidity control at the same time. The result is increased energy saving through the recovery of e.g. heat that would be otherwise wasted in the environment by traditional ventilation systems.

A twin operation system built from rigid material can pre-condition fresh air by recovering the heat from the air driven out. It incorporates two ventilation fan motors, fresh air intake and extraction fan, a filter, and the recovery element, together with a wired controller with operation choices and a direction electric damper.

Energy saving. The built in heat recovery element can perform a recovery rate of more than 70%, recycling heat to be wasted to the air intake.

Fresh air. The intake air filter keeps fresh air dust free. The recovery element material is specially chosen for their anti-bacterial and anti-odor characteristics.

Gree GMV HR 2 series with modular installation capability design of up to 180kW in combination to the wide range of indoor unit choices offers an advanced solution for medium and big commercial applications.

• GMV-Pdhm heat recovery series breaks the limits of classic VRF applications, since indoor units can operate under both cooling and heating operation at the same time. Energy saving takes place from the recovery of energy that would be traditionally released in the environment, that is uniquely recovered and channeled for the alternative operation purpose in spaces that require it and vice versa , under five different operation combinations.
• Wide temperature operation range. The units can operate in a wide ambient temperature range decreasing thus capacity loss due to outdoor temperature.
• The units can reach a high energy efficiency through energy recovery, utilized for cooling or heating of individual spaces in parallel.
• The combined COP (ECOP) can reach 6,8 during recovery mode, the highest available in VRF applications.
• Utilizing new technology DC Inverter compressors with a permanent magnet motor and a high pressure intake chamber, together with All DC Inverter fan motors and bigger area heat exchangers GREE VRF reach an EER of 4,6 under partial load.
