Function Description
High Efficiency
Full Load Operation
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.
Excellent Part
Load Performance
By using two 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
compress 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.
Compact Design With
Small Footprint
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.
Quiet Operation
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.
Superior Controls
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)
