By using multi compressors on each chiller, unloading characteristics and part load

performance are outstanding. Integrated part load value (IPLV) is a part load

performance indicator as outlined in ARI Standard 550/590-1998. The IPLV rating

compares the performance of different chillers under identical conditions. When the

IPLV is listed in EER (Energy Efficiency Ratio), a higher EER will indicate that the chiller's

overall performance is better.

The chillers have a reputation for a compact design and small footprint. A small

footprint can save installation costs by minimizing the size of the concrete mounting

pad or reduces the amount of structural steel if the unit is mounted on the rooftop.

The chillers are designed with quiet scroll compressors. Fans are selected for good

performance and lower sound levels. The attention to detail with sound is critical in the

design. Small issues such as refrigerant piping, supports for piping, securing

components to the structure are all important to making a quiet product. We proudly

publish our sound performance.

Quiet Operation

Excellent Part Load Performance

Compact Design with Small Footprint

GREE Central Air Conditioners

Utilizing new scroll compressor technology, the chillers meet or exceed the

performance requirements of ASHRAE 90.1. All system components are selected for

optimum performance, including the condenser coil areas and evaporator sizes.

High Efficiency Full Load Operation

3.2 Standard Specifications

GREE has provided the latest technology in controlling the chillers. The new controller

provides a“user friendly”environment for the operator. The control logic is designed

to provide maximum efficiency, to help provide continuing operation in unusual

operating conditions through proactive controls, and to provide a history of conditions

to aid in problem resolutions. Perhaps the greatest benefit is the Protocol for

integrating with your building automation system (BAS).

Superior Controls

Compressors

These rugged hermetic compressors are constructed with an integral cast iron frame,

cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for

each compressor. One to thity-two compressors can run, depending on the load of

the system, resulting in excellent Part-load efficiency. Each refrigerant circuit has

specially designed oil and gas equalization lines to control oil migration.

The design also offers radial and axial compliance, a large internal volume for liquid

handling, a removable suction screen, and a rotary dirt trap and oil screen. In

addition, the compressor is self-compensating for wear, handles moderate liquid

slugging, and inherently yields high efficiency.
