HONWO-T3 R32 Residential Chiller Features
HONWO T3 R32 DC Inverter Residential Small Chiller delivers 6–16 kW of efficient cooling and heating in high-ambient environments up to 56 °C. Utilizing eco-friendly R32 refrigerant (GWP > 66 % lower than R410A) and twin-rotary DC inverter compressors, it achieves market-leading seasonal efficiencies of up to EER 5.91 and COP 5.10 at full load for both cooling and heating modes. Designed for residential or light-commercial use—villas, small hotels, apartments—it features plate-type water heat exchangers, electronic expansion valves, integrated hydronic controls, and ultra-quiet axial fans (60–67 dB(A)). Its compact footprint, “water-pipe only” installation, and wide operating envelope (–25 °C to +56 °C cooling; –25 °C to +35 °C heating) deliver turnkey comfort in tropical climates without the need for supplemental chillers.

What is an R32 small/mini chiller?
A compact air-cooled chiller using R32 refrigerant for residential or light-commercial HVAC of up to 16 kW capacity.
Centralized chilling with integrated hydronic circuits simplifies installation and maintenance, and offers quieter operation in living spaces.
DC inverters modulate compressor and fan speeds to precisely match load, reducing on/off cycling losses by up to 30 %.
R32 boasts a GWP > 66 % lower than R410A and superior thermodynamic performance for higher COP/EER.
While primarily a chiller, models can be configured for heat-pump operation to produce hot water up to 60 °C.
Rated to operate from –25 °C to +56 °C in cooling mode and from –25 °C to +35 °C in heating mode.
No refrigerant piping on site—the monoblock requires only water-pipe connections and electrical power.
Periodic coil cleaning, filter checks, and annual inspection of electronic expansion valves and sensors.
Sound power levels range 60–67 dB(A), similar to a home dishwasher, ensuring minimal disturbance.
Yes—offer BMS integration via Modbus or BACnet options for remote monitoring and control.
