Introduction to R290 Air Source Heat Pump

I. Core Applications

This product focuses on building space heating and is compatible with various radiators such as fan coil units, underfloor heating, and radiators. It also supports domestic hot water (DHW) supply and air conditioning functions, covering needs from residential buildings to large-scale structures, and is particularly suitable for cold regions.

II. Key Functions

Heating Foundation: Operable at -25℃ with a maximum outlet water temperature of 75℃; the 4kW model maintains 100% rated output at -10℃; intelligent on-demand defrosting; anti-freeze logic activates when water temperature < 5℃ (maintaining 15℃); anti-freeze valve automatically opens at < 3℃ ±1℃.

Safety Protection: Independent ventilation channel prevents refrigerant accumulation and cools electrical components; explosion-proof PCBs (including sealed relays and ceramic fuses) with dustproof, moisture-proof, and high-temperature resistance.

Intelligent Control: Color controller for daily/monthly/annual energy consumption checking and scenario visualization; supports APP remote temperature adjustment and fault checking, as well as remote platform monitoring of multiple units; compatible with Modbus BMS and third-party thermostats.

Expansion Adaptability: Up to 8 units can be cascaded (maximum 128kW), and it can be mixed with boilers; the series integrates hydraulic components to simplify installation.

III. Core Advantages

Strong Low-Temperature Performance: Stable operation at -25℃;

High Energy Efficiency & Environmental Friendliness: 4/7/12kW models achieve A+++ energy efficiency at 35/55℃ water temperature; R290 refrigerant is environmentally friendly;

Low Noise: Equipped with Quiet technology, the 7kW model produces only 35dB(A) at 2 meters, meeting European standards;

Safe & Reliable: Multi-layer protection reduces failure risks;

Flexible & Easy to Install: Cascaded/mixed applications adapt to different scenarios, saving space and costs;
