FAQS
A 12,000 BTU mini split can cool an area of approximately 450 to 550 square feet. This estimate is based on the general rule of 20 BTUs per square foot. For standard-sized living rooms, larger bedrooms, or as an air conditioner for small room like studio apartments, this unit is typically a good fit.
For Della's Opitma (TP) series mini split, the breaker size depends on the voltage: the 115V version requires a 25-amp breaker, while the 230V version requires a 15-amp breaker.
For the Versa (TL) series mini split, the 115V version also requires a 25-amp breaker, and the 230V version requires a 15-amp breaker, similar to the Opitma (TP) series.
For the Motto (JA) series mini split, the breaker size is slightly smaller: the 115V version needs a 20-amp breaker, and the 230V version requires a 10-amp breaker.
Della's 12K BTU mini split in the Opitma (TP) series uses 920 watts for cooling, making it more efficient than some small window ac units or older mini split systems.
To estimate the electricity cost, if the mini split runs for 8 hours a day, the daily energy consumption would be:
- 920 watts × 8 hours = 7,360 watt-hours = 7.36 kWh.
If the electricity rate is $0.15 per kWh, the daily cost would be:
- 7.36 kWh × 0.15 USD = 1.10 USD/day.
For a month (30 days), the estimated cost would be:
- 1.10 USD/day × 30 = 33 USD/month.
For Della's 12,000 BTU mini split AC in the Opitma (TP) series:
- The 115V model draws 8.2 amps.
- The 230V model draws 4.1 amps.
For Della's 12,000 BTU mini split AC in the Versa (TL) series:
- The 115V model draws 10.2 amps.
- The 230V model draws 5.1 amps.
For Della's 12,000 BTU mini split AC in the Motto (JA) series:
- The 115V model draws 9.2 amps.
- The 208V model draws 4.9 amps.
On average, 12,000 BTU mini splits typically draw 10–15 amps, depending on the voltage and energy efficiency. Lower amperage indicates better energy efficiency, reduced strain on your electrical system, and potentially lower operating costs, making it an excellent choice for long-term savings.
The electrical requirements for Della's Opitma (TP) series 12,000 BTU mini split are similar to a single room ac system, with specifications as follows:
Power Supply:
- 115V version: Requires a 115V / 60 Hz / 1P power supply.
- 230V version: Requires a 208-230V / 60 Hz / 1P power supply.
Power Consumption:
- Both versions consume 920 watts for cooling and 910 watts for heating.
Amperage:
- 115V version: Rated current is 8.2 amps.
- 230V version: Rated current is 4.1 amps.
Breaker Size:
- 115V version: Requires a 25-amp breaker.
- 230V version: Requires a 15-amp breaker.
Minimum Circuit Ampacity (MCA):
- 115V version: 17 amps.
- 230V version: 11 amps.
Wire Gauge:
- Both versions require a minimum wire size of 16 AWG.
For other Della series, such as the TL or JA models, always refer to the specific product manual for accurate electrical requirements.
Yes, a 12,000 BTU air conditioner can handle extreme temperatures effectively, much like a standing ac unit designed for harsh climates. It typically cools effectively in temperatures up to 115°F (46°C) and heats in temperatures as low as 5°F (-15°C),
Yes, a 1-ton mini split is quiet enough for use in bedrooms or home offices, outperforming many mini split ac and heat models in noise reduction. For example, Della's 12,000 BTU air conditioner operates at an indoor noise level of 26-45 dBA, which is comparable to a quiet library or soft whisper. This ensures minimal disruption, making it ideal for restful or focused environments.
The Della 12K BTU mini split system is equipped with an air filter, a feature also common in dual-zone mini split and multi-zone mini split system designs. While its primary focus is efficient cooling and heating, the air filtration ensures a comfortable and healthier environment for your home.
The Opitma (TP) series 1-ton mini split is the better choice overall, though larger spaces might consider an 18,000 BTU mini split or 24,000 BTU mini split for enhanced coverage.
Here’s why:Energy Efficiency:
- TP: 920W cooling, 910W heating, 8.2A/4.1A current draw.
- TL: 1130W cooling, 1090W heating, 10.2A/5.1A current draw.
Noise Levels:
- TP: 27-45 dBA.
- TL: 27-42 dBA.
Size & Weight:
- TP: Slightly larger and heavier.
- TL: More compact and lighter.
