Solar Heating, Cooling & Refrigeration Applications

Solar HVAC and refrigeration for locations where power is expensive, unreliable, or off-grid

Two issues persist throughout residences, public buildings, cold storage facilities, and off-grid locations: the cost of electricity and the reliability of supply. Villas, self-built dwellings, and guesthouses have continual cooling and heating expenditures. Hotels, malls, schools, and hospitals are all high-energy users with consistent operational costs. Small cool rooms and fresh product storage require continuous 24-hour power at high, sustained loads. And islands, farms, and isolated sites are frequently located beyond reliable grid coverage, with some still running diesel generators with relatively high fuel and operating costs.

JUNDE's solar mini-split air conditioners solve this by intelligently combining solar, mains, and storage to meet high cooling and heating loads while cutting operating costs, offering cooling and heating in one unit for year-round use in all climate zones. The solar direct-drive condensing units reduce cold-storage electricity costs by prioritising photovoltaic power, and because cold rooms have a huge, unshaded roof area and a consistent round-the-clock load, they are well suited to a rooftop PV array, which also shields the roof from the sun and rain.

    Residential

    Solar air conditioning is frequently implemented in residential structures. A solar mini-split system enhances daily comfort while simultaneously decreasing household electricity expenses. The inverter-driven split unit operates silently, satisfying the comfort and low-noise requirements of villas, self-built houses, and guesthouses.

    Commercial & Institutional

    Solar air conditioning is a critical application in public and commercial structures. Solar air conditioning is a cost-effective solution for hotels, apartments, shops, office buildings, schools, and hospitals with high energy demand. Additionally, it contributes to the establishment of a visible green image and an environmental profile.

    Cold Chain & Cold Storage

    Food preservation entails keeping it cool during transportation, processing, storage, and distribution. Many cold stores use massive amounts of electricity each year; therefore, reducing energy consumption has become a critical, practical issue for the industry.

    Off-Grid & Remote Areas

    Remote places often have limited grid coverage, unstable supply, and expensive electricity costs. Some locations rely on diesel generators to meet their daily requirements, which incur significant operating costs.
