In the modern trend of refrigeration technology, Hitachi air conditioners consistently maintain their leading position thanks to their pioneering innovation in refrigerants. The shift from R410A to R32 marks a significant step forward in both operational efficiency and environmental protection standards. If you are looking for an optimal, energy-efficient cooling solution for your living and working spaces, this article from U.P TECH will help you analyze in detail the outstanding advantages of the new generation R32 refrigerant.
Overview of the new generation of Hitachi air conditioners using R32 refrigerant
Refrigerant (air conditioning gas) plays a core role in the heat absorption and dissipation cycle of an air conditioning system. For many years, R410A was the standard replacement for R22 gas. However, along with stringent environmental protection requirements, Hitachi has comprehensively upgraded its product lines such as airCore 600 and Commercial Inverter to use R32 refrigerant.
This upgrade helps the device achieve superior energy efficiency while significantly reducing its negative impact on climate change. The new generation of Hitachi air conditioners is now officially distributed by U.P TECH, with a full range of models: from cassette ceiling-mounted, ducted concealed ceiling, to surface-mounted ceiling air conditioners.

What are the advantages of Hitachi air conditioners using R32 refrigerant compared to R410A?
When comparing R32 and R410A refrigerants directly on the same Hitachi inverter compressor system, R32 demonstrates overall superiority across many technical criteria:
1. Environmentally friendly and reduces the risk of global warming
- GWP (Global Warming Potential): Refrigerant R32 has a GWP of only 675, which is 67.7% lower than the 2,090 rating of R410A.
- ODP (Ozone Depletion Potential): Both R32 and R410A have an ODP of zero, meaning they do not contribute to ozone layer depletion.
- Low carbon emissions help minimize the greenhouse effect during operation.
2. High cooling performance and outstanding energy efficiency
- High heat transfer capability: R32 refrigerant has impressive heat transfer properties, allowing the compressor to reach the set temperature faster and minimizing runtime.
- Exceptionally high SEER: Hitachi’s R32 Inverter air conditioner series achieves a Seasonal Energy Efficiency Ratio (SEER) of up to 21.94 (specifically the airCore 600 Cassette model RCI-B18TFT5NA), significantly exceeding the 14.0–17.0 average of older R410A models.
- Optimized refrigerant charge: The R32 system requires approximately 70% less refrigerant by weight compared to R410A for the same cooling capacity, resulting in cost savings and enhanced safety.
3. Operates reliably in extreme temperature conditions
Hitachi's R32 compressor system delivers stable cooling performance even when outdoor temperatures reach an extreme 48°C.
Combined with Cascade Vector DC Inverter technology, the unit operates quietly, minimizes vibration, and extends its service life.
| Comparison criteria | R32 refrigerant (New generation) | Refrigerant R410A (Older generation) |
| GWP (Greenhouse Gas Impact) Index | 675 (Short) | 2090 (High) |
| ODP (Ozone Depletion) Index | 0 (Safe) | 0 (Safe) |
| Energy Efficiency Ratio (SEER) | Extremely high (Up to 21.94) | Average (14.0 - 17.1) |
| Required refrigerant charging rate | 70% (Save) | 100% |
| Maximum operating ambient temperature | Come 48°C | Up to 46°C |

Breakthrough technologies integrated into Hitachi air conditioners using R32 refrigerant
In addition to the advantages offered by the R32 refrigerant, Hitachi air conditioners distributed by U.P TECH feature a range of proprietary technologies designed to enhance user comfort and safeguard health:
- FrostWash™ self-cleaning technology: Freezing dirt and debris on the heat exchanger coils, then thawing the ice to wash away bacteria, helps maintain a clean airflow.
- Wasabi & Stainless Pre-Filter: A stainless steel filter infused with Wasabi extract that eliminates up to 99% of bacteria, mold, and allergens, while also removing PM2.5 fine dust.
- Smart control with airCloud Home & Smart-Fence: Monitor energy consumption and automatically turn on/off based on your smartphone's geofencing when you leave or return home.
- Corrosion-resistant heat exchanger (Blue Fin / Green Fin): The premium anti-corrosion coating protects the outdoor unit from sea salt spray, moisture, and microorganisms.
- Fireproof and insect-proof electrical box: The circuit board is protected in a sealed 0.5mm thick metal box, preventing the risk of short circuits and the intrusion of insects and geckos.
