Product Description-GREE Top Discharge Condensing Unit Inverter Series

GREE Top Discharge Condensing Unit Inverter Series is the most flexible solution in central air conditioning systems for different types of buildings. Compact design of outdoor units makes installation easier and multiple modular combination possibilities up to 180 Kw. Maximum number of indoor units that can be connected to a VRF system is up to 110 units. Maximum piping length reaches 1000m, maximum distance beetwen indoor and outdoor unit is up to 150m, maximal height beetwen indoor units is up to 15m, maximum height beetwen indoor and outdoor unit is 50m. The new GMV5 Mini generation adoptes high-performance compressor wich greately improoves energy efficiency, maintainig quite levels of noise during operation. Compressors are designed to operate normally in a wide temperature range thus reducing power loss and maintaining a high performance level.

Main Features-GREE Top Discharge Condensing Unit Inverter Series

High-efficiency inverter compressor; 

high-efficiency PMSM; 

high-efficiency heat exchanger; 

180°vector control technology

High-frequency operation and rapid cooling/heating

Name: GREE Top Discharge Condensing Unit Inverter Series

The DC inverter compressor of gree top discharge condensing unit inverter series will run cooling at the largest power input and largest airflow each time it is started until the set temperature is approached. Then, it runs at a low speed and low power input, which thus can not only keep the temperature from fluctuating but also avoid frequently starting and stopping the compressor so as to prolong its service life.

High-efficiency PMSM

As for the DC inverter compressor of gree top discharge condensing unit inverter series  with the permanent magnetic synchronous motor(PMSM), there is no current through the motor rotor, no eddy current loss and little heat produced, which means less ineffective power loss so that the motor's efficiency can be improved and the power input can be reduced greatly.

Micro channel heat exchanger

Micro channel heat exchanger (MCHX) transfers heat through multiple flat fluid-filled tubes containing small channels, which can enhance gree top discharge condensing unit inverter series' heat transfer coefficient so that heat exchange efficiency is increased by 30% compared to the normal fined tube heat exchanger. (Note: For cooling only condensing unit)

Wide operation voltage range

Wide operation voltage range

Gree top discharge condensing unit inverter series can safely operate within 187~254V.

Application: GREE top discharge condensing unit inverter series

Heating, ventilation, and air conditioning (HVAC[1]) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC&R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).

HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
