Three Gree Compressor Technologies Rated at 'International Advanced Level'

Gree announced that three compressor technologies related to cooling and heating cycles in air conditioners have passed independent expert review and achieved international advanced level. The solutions are targeted at residential central air conditioners and heat pumps with both heating and cooling functions, and according to the company, set a new performance benchmark in these segments.

Three Technologies and Their Purpose

The solutions that passed the expert review include:

• Rotary-cylinder compressor for air conditioning — a structural innovation providing lower noise levels and a more stable cooling cycle.
• High-efficiency parallel compressor with vapor injection — improved energy efficiency across the full range of operating modes: from light to full load, in summer heat and winter cold.
• Reverse top-and-bottom airflow technology — in cooling mode, air is directed downward; in heating mode, warm air is directed downward, solving the problem of uneven cooling and «floating» warm air at the ceiling.

Key Parameters

According to test data, the energy efficiency of the parallel compressor with vapor injection has been improved by up to 15.1 %. Gree heat pump models with ultra-low-temperature mode are capable of stable heating at temperatures from minus 30 to minus 40 °C, while retaining cooling capability in high-temperature conditions. The solutions are adapted for the pure-heating market in northern regions and year-round dual-circuit supply in southern regions.

Channel Transformation

Alongside the technological upgrade, Gree continues its distribution network reform: the company is gradually moving away from the model of imposing volume targets on dealers and shifting to evaluation based on actual retail sales. Dealers are encouraged to transform from stocking suppliers into heating and cooling solution providers. In the industry, this is happening against the backdrop of frequent disputes over inventory worth 10 million yuan.
