About Us
Ningbo Junde Environmental Technology Co., Ltd. specializes in the design, manufacture, and sale of solar HVAC and refrigeration equipment. Our product line includes photovoltaic direct-drive refrigeration systems and solar air conditioners. Our equipment is designed to provide low-carbon, efficient, and stable temperature control for residential, commercial, industrial, and off-grid environments; it is based on our proprietary photovoltaic intelligent control technology. Our product line comprises two series: solar air conditioners and solar direct-drive freezer and refrigerator condensing units.
Core Business
Solar wall-mounted air conditioners.
AC/DC hybrid split units with capacities of 12,000 and 18,000 BTU operate in four modes: full-PV, micro-grid, AC/DC hybrid, and energy storage. They are appropriate for a variety of contexts, including residences, mobile homes, workplaces, stores, farms, off-grid buildings, telecom base stations, and more.
Solar-powered freezer and cooler units.
Photovoltaic DC drives the inverter compressor directly, with power ratings ranging from 3 to 12 HP. Fruit and vegetable preservation rooms, food cold storage, quick-freeze rooms, agricultural product storage, and cold-chain logistics hubs are all possible applications.
Core Technological Advantages
Self-developed intelligent control.
Our equipment is based on our proprietary photovoltaic intelligent control technology, which serves as the foundation for the four-mode power management system, allowing solar, mains, and storage to hand off automatically for continuous operation.
Four-mode intelligent power supply.
Full-PV, micro-grid, AC/DC hybrid, and energy-storage modes transition automatically, ensuring that solar, mains, and batteries operate together flawlessly and equipment runs consistently at all times.
Wide-voltage design for international markets.
PV input ranges from 80 to 320 volts, and the systems are compatible with 110 and 220 volt mains, allowing them to adapt to the standard home voltages used in many nations.
Application Scenarios
-
Residential
Villas, self-built houses, and guesthouses that prioritise comfort and energy efficiency.
-
Commercial and institutional
Hotels, apartments, retail stores, office buildings, schools, and hospitals use a lot of energy.
-
Cold chain and storage
Cold chain and storage include small cold rooms, fresh produce storage, agricultural product storage, food processing, and cold-chain logistics initiatives.
-
Off-grid and weak-grid areas
Islands, farms, isolated regions, and projects with no grid coverage, which replace traditional diesel generation while lowering operating costs.
