Unparalleled efficiency from SunTrac and 30 Ton chiller install

In December 2019, NIDON Clean Energy completed a breakthrough installation involving a 30 Ton Carrier chiller and four 8-foot SunTrac panels. This unit, located in the Honolulu Harbor in Hawaii, became the first active chiller in the world that runs with the SunTrac Solar Thermal SmartPanel™ and now reflects record-breaking amperage readings as a result.

This chiller is rated to typically draw about 63 amps but with supplementary power from the SunTrac panels, the load across three days in 28°C experienced a 75% decrease with a near steady state amp draw of 16 amps:

Timestamps reflected on the above data captures follow local Philippine time (PHT) and is to be adjusted back 18 hours to depict actual amp draw with respect to time of day in Honolulu, Hawaii (HST).

Along with the massive drop in amp draw, there is a corresponding decrease in the work being conducted by the unit’s digital scroll compressor leading to a significant reduction in the machine’s wear and tear on top of substantial electrical cost savings.

Data is being tracked and recorded by an eGauge metering device in a three-phase configuration and placed inside an outdoor-rated enclosure:

Update: Efficiency data across two weeks

Below is a screen capture of meter readings for the first two weeks of recording with the eGauge. The compressor amp draw still averages at 15-16 amps, with significant dips between midnight and dawn due to the cooler ambient temperature.

Update: One month’s worth of meter readings

A month of meter readings shows amp draw still at an average of 15-16 amps.

NIDON Clean Energy unlocks commercial cooling market with breakthrough install

NIDON Clean Energy has just completed the first SunTrac installation on a commercial chiller system.

Located in Honolulu, Hawaii, this 30 Ton Carrier chiller is the first active chiller in the world that runs with the SunTrac Solar Thermal SmartPanel™.

The recorded amp draw by compressors post-installation is reduced by 60%. Energy savings will correspond with amperage drop to the compressors, along with reduced wear.

For the Hawaii market, this is foundational to achieving the Hawaii Clean Energy Initiative which aims to achieve 100% renewable energy reliance by 2045. SunTrac has been successfully deployed across Hawaii on all major brands of air conditioning, to now include commercial systems. The technology reduces demand charges and electrical usage, leading to less land for solar, wind, and battery, protecting the people and the beauty of the islands in the process.
