GRAD Residential Dedicated Inverter Air Source Heat Pump: Infusing Green Energy into Comfortable Living
Under the guidance of the "Dual Carbon" goals and clean heating policies, how does one select a heating and cooling solution for homes or projects that is both highly efficient and environmentally safe? Shandong GRAD Group offers the ideal answer: the Residential Dedicated Inverter Air Source Heat Pump. This system integrates winter heating and summer cooling, using smart technology to create a spring-like indoor environment year-round.
An Integrated Solution, Free from Heating and Cooling Worries
This heat pump utilizes advanced DC inverter and enhanced vapor injection (EVI) technologies, with a core powered by a twin-rotary compressor. It intelligently adjusts its operation based on outdoor temperatures and indoor demands. Even in extreme cold as low as -30°C, it maintains strong and stable heating performance. Paired with a high-efficiency DC inverter motor, it ensures quiet operation with low noise and a long lifespan. One unit serves two purposes with flexible adaptation: it connects to underfloor heating or radiators for warmth in winter, and delivers cool air through fan coil units in summer, truly achieving "combined heating and cooling." The system supports various end-unit types, easily matching different house layouts and decoration requirements.
Wide Applicability, Facilitating Green Transformation
Policy-Driven Scenarios: Perfectly aligns with clean heating initiatives like the Northern "Coal-to-Electricity" and "Gas-to-Electricity" conversion projects, serving as a preferred equipment for implementing national policies.
Comfort Upgrade Choice: An ideal choice for both new residential constructions and the replacement/upgrade of traditional heating systems, enhancing quality of life.
Areas without Central Heating: Particularly suitable for towns, villages, and rural areas lacking central heating infrastructure, providing cost-effective heating solutions for community consolidation and individual homes.
Core Advantages, Demonstrating Exceptional Quality
Eco-Friendly & Energy Efficient: Uses environmentally friendly R410A refrigerant (non-ozone depleting, lower GWP); full DC inverter technology significantly improves energy efficiency compared to traditional fixed-speed units, saving electricity and costs.
Stable & Reliable: Features wide voltage design (160V-270V), adapting to grid fluctuations; intelligent defrosting and temperature compensation functions minimize heat loss for efficient operation.
Safe & Quiet: Patented anti-freeze structure and automatic freeze protection operation eliminate the risk of freezing and cracking; multiple noise reduction technologies create a tranquil and comfortable home environment.
