Capacity
At the principal ASHRAE rating condition—approximately 45°F evaporating and 130°F condensing:
- Cooling capacity: 8,464 BTU/h
- Power consumption: 1,160W
- Current: 12.2A
- Efficiency: 7.30 BTU/Wh
At a lower 95°F condensing temperature, its capacity varies considerably:
| Evaporating temperature |
Cooling capacity |
| −4°F |
3,919 BTU/h |
| +5°F |
4,962 BTU/h |
| +14°F |
6,204 BTU/h |
| +23°F |
7,642 BTU/h |
| +32°F |
9,273 BTU/h |
Important: NT6220GKV is not a true low-temperature compressor. Its published evaporating limit only goes down to −4°F. Therefore, it is appropriate for reach-in refrigerators, beverage coolers, display cases and similar medium-temperature equipment—but generally not for a −10°F freezer box.
