High Efficiency and Excellent Performance

Eco-friendly Refrigerant R32

The R32 refrigerant contributes to meeting F-gas regulation targets, offering a perfect solution for achieving new European CO2 emission targets. Key features include Zero Ozone Depletion Potential (ODP), Lower Global Warming Potential (GWP), less charge amount for the same capacity, and being a single component refrigerant that is easy to handle and recycle.

A comparison chart shows R32 has a significantly lower GWP (675) compared to R410A (2088), and requires a lower charge ratio (74%) for equivalent performance, resulting in lower effective CO2 equivalent emissions.

High Efficiency A+++

The Hi-Therma series provides an efficient solution for home heating and hot water. It achieves top-class A+++ energy classification for low-temperature water conditions and A++ for mid-temperature conditions, leading to savings on energy bills and reduced environmental impact.

Example energy labels for models AHW-060HCDS1 and AHM-060HCDSAA show A+++ for 35°C water outlet and A++ for 55°C water outlet.

Advanced Compressor and Operation

High-efficiency DC Inverter Compressor

The system features a high-efficiency DC inverter twin rotary compressor with a unique dual-pressure chamber design and symmetrical location. This design effectively reduces vibration and noise, improving performance, especially at low frequencies. The compressor also includes a small lubricating oil injection volume with stable oil return and a gas-liquid separator for enhanced reliability.

Key compressor features include:

• 1. High-efficiency motor: Optimizes motor design for improved compressor performance.
• 2. Optimized rotor design: Lowers the compressor's center of gravity to reduce noise and vibration.
• 3. Flat mechanism design: Enhances volumetric efficiency and overall performance.
• 4. Screw interactive fastening: Improves fastening effect and reduces core deformation.

Wide Operation Range

The heat pump guarantees stable operation down to -25°C outdoor temperatures, meeting heating demands in cold regions. It can deliver up to 60°C leaving water from the hydro box. The Domestic Hot Water (DHW) operation range extends to 40°C, and the water in the tank can reach a maximum of 75°C for effective sterilization.
